Adding a Connection to SAP HANA XSA

To add a connection to SAP HANA XSA:

1. In the application console, navigate to the Connections page.
2. At the Add Connections panel, select the icon for the connection you want to add.
3. If the SAP HANA XSA icon is not available, click the Add More icon to download and install the SAP HANA XSA connector from the CData site.

For required properties, see the Settings tab.

For connection properties that are not typically required, see the Advanced tab.

SAP HANA XSA uses the OAuth authentication standard. Before connecting, it is necessary to establish an SAP HANA XSA OData Service. See Creating a Custom OAuth App for a guide.

To connect to SAP Hana XSA using password-based OAuth:

• OAuthClientId: Set this to the Client Id specified in the UAA service JSON file.
• OAuthClientSecret: Set this to the Client Secret specified in the UAA service JSON file.
• URL: Set this to the OData service endpoint.
• XSUAAURL: Set this to the UAA service url.
• User: Set your accounts username.
• Password: Set your accounts password

Once you've configured the OData Service, you can establish a connection using Custom Credentials.

This section details a selection of advanced features of the SAP HANA XSA Sync App.

User Defined Views

The Sync App supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views .

SSL Configuration

Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats;. For further information, see the SSLServerCert property under "Connection String Options" .

Firewall and Proxy

Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.

Query Processing

The Sync App offloads as much of the SELECT statement processing as possible to SAP HANA XSA and then processes the rest of the query in memory (client-side).

For further information, see Query Processing.

Logging

For an overview of configuration settings that can be used to refine CData logging, see Logging. Only two connection properties are required for basic logging, but there are numerous features that support more refined logging, which enables you to use the LogModules connection property to specify subsets of information to be logged.

Customizing the SSL Configuration

To enable TLS, set the following:

• URL: Prefix the connection string with https://

With this configuration, the Sync App attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.

To specify another certificate, see the SSLServerCert connection property.

Connecting Through a Firewall or Proxy

HTTP Proxies

To authenticate to an HTTP proxy, set the following:

• ProxyServer: the hostname or IP address of the proxy server that you want to route HTTP traffic through.
• ProxyPort: the TCP port that the proxy server is running on.
• ProxyAuthScheme: the authentication method the Sync App uses when authenticating to the proxy server.
• ProxyUser: the username of a user account registered with the proxy server.
• ProxyPassword: the password associated with the ProxyUser.

Other Proxies

Set the following properties:

• To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
• To tunnel the connection, set FirewallType to TUNNEL.
• To authenticate, specify FirewallUser and FirewallPassword.
• To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

Overview

This section shows the available API objects and provides more information on executing SQL to SAP HANA XSA APIs.

Key Features

• The Sync App models the SAP HANA XSA OData Service as relational tables and views, allowing you to write SQL to query SAP HANA XSA data.
• Stored procedures allow you to execute operations to SAP HANA XSA.
• Live connectivity to these objects means any changes to your SAP HANA XSA account are immediately reflected when using the Sync App.

Tables

The Sync App dynamically obtains table metadata from the SAP HANA XSA OData service. See Metadata Discovery for more information.

Views

The Sync App dynamically obtains read-only view metadata from the SAP HANA XSA OData service. See Metadata Discovery for more information.

Stored Procedures

Stored Procedures are function-like interfaces to SAP HANA XSA. Stored procedures allow you to execute operations to SAP HANA XSA, including downloading documents and moving envelopes.

Stored procedures are function-like interfaces that extend the functionality of the Sync App beyond simple SELECT/INSERT/UPDATE/DELETE operations with SAP HANA XSA.

Stored procedures accept a list of parameters, perform their intended function, and then return any relevant response data from SAP HANA XSA, along with an indication of whether the procedure succeeded or failed.

This section provides a complete list of the OAuth properties you can configure in the connection string for this provider.

---

Property	Description
OAuthClientId	Specifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.
OAuthClientSecret	Specifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).
Scope	Specifies the scope of the authenticating user's access to the application, to ensure they get appropriate access to data. If a custom OAuth application is needed, this is generally specified at the time the application is created.

Specifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.

Remarks

This property is required in two cases:

• When using a custom OAuth application, such as in web-based authentication flows, service-based authentication, or certificate-based flows that require application registration.
• If the driver does not provide embedded OAuth credentials.

(When the driver provides embedded OAuth credentials, this value may already be provided by the Sync App and thus not require manual entry.)

OAuthClientId is generally used alongside other OAuth-related properties such as OAuthClientSecret and OAuthSettingsLocation when configuring an authenticated connection.

OAuthClientId is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can usually find this value in your identity provider’s application registration settings. Look for a field labeled Client ID, Application ID, or Consumer Key.

While the client ID is not considered a confidential value like a client secret, it is still part of your application's identity and should be handled carefully. Avoid exposing it in public repositories or shared configuration files.

For more information on how this property is used when configuring a connection, see Establishing a Connection.

Specifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).

Remarks

This property (sometimes called the application secret or consumer secret) is required when using a custom OAuth application in any flow that requires secure client authentication, such as web-based OAuth, service-based connections, or certificate-based authorization flows. It is not required when using an embedded OAuth application.

The client secret is used during the token exchange step of the OAuth flow, when the driver requests an access token from the authorization server. If this value is missing or incorrect, authentication fails with either an invalid_client or an unauthorized_client error.

OAuthClientSecret is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can obtain this value from your identity provider when registering the OAuth application.

Notes:

• This value should be stored securely and never exposed in public repositories, scripts, or unsecured environments.
• Client secrets may also expire after a set period. Be sure to monitor expiration dates and rotate secrets as needed to maintain uninterrupted access.

For more information on how this property is used when configuring a connection, see Establishing a Connection

Specifies the scope of the authenticating user's access to the application, to ensure they get appropriate access to data. If a custom OAuth application is needed, this is generally specified at the time the application is created.

Remarks

Scopes are set to define what kind of access the authenticating user will have; for example, read, read and write, restricted access to sensitive information. System administrators can use scopes to selectively enable access by functionality or security clearance.

When InitiateOAuth is set to GETANDREFRESH, you must use this property if you want to change which scopes are requested.

When InitiateOAuth is set to either REFRESH or OFF, you can change which scopes are requested using either this property or the Scope input.

This section provides a complete list of the SSL properties you can configure in the connection string for this provider.

---

Property	Description
SSLServerCert	Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Remarks

If you are using a TLS/SSL connection, use this property to specify the TLS/SSL certificate to be accepted from the server. If you specify a value for this property, all other certificates that are not trusted by the machine are rejected.

This property can take the following forms:

Description	Example
A full PEM Certificate (example shortened for brevity)	-----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE-----
A path to a local file containing the certificate	C:\cert.cer
The public key (example shortened for brevity)	-----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY-----
The MD5 Thumbprint (hex values can also be either space- or colon-separated)	ecadbdda5a1529c58a1e9e09828d70e4
The SHA1 Thumbprint (hex values can also be either space- or colon-separated)	34a929226ae0819f2ec14b4a3d904f801cbb150d

Note: It is possible to use '*' to signify that all certificates should be accepted, but due to security concerns this is not recommended.

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.

---

Property	Description
FirewallType	Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
FirewallServer	Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.
FirewallPort	Specifies the TCP port to be used for a proxy-based firewall.
FirewallUser	Identifies the user ID of the account authenticating to a proxy-based firewall.
FirewallPassword	Specifies the password of the user account authenticating to a proxy-based firewall.

Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.

Remarks

A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.

Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.

Note: By default, the Sync App connects to the system proxy. To disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.

The following table provides port number information for each of the supported protocols.

Protocol	Default Port	Description
TUNNEL	80	The port where the Sync App opens a connection to SAP HANA XSA. Traffic flows back and forth via the proxy at this location.
SOCKS4	1080	The port where the Sync App opens a connection to SAP HANA XSA. SOCKS 4 then passes theFirewallUser value to the proxy, which determines whether the connection request should be granted.
SOCKS5	1080	The port where the Sync App sends data to SAP HANA XSA. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes.

To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.

Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.

Specifies the SSL type to use when connecting to the proxy server specified in the ProxyServer connection property.

Remarks

This property determines when to use SSL for the connection to the HTTP proxy specified by ProxyServer. You can set this connection property to the following values :

AUTO	Default setting. If ProxyServer is set to an HTTPS URL, the Sync App uses the TUNNEL option. If ProxyServer is set to an HTTP URL, the component uses the NEVER option.
ALWAYS	The connection is always SSL enabled.
NEVER	The connection is not SSL enabled.
TUNNEL	The connection is made through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy.

Specifies a semicolon-separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property.

Remarks

The ProxyServer is used for all addresses, except for addresses defined in this property. Use semicolons to separate entries.

Note: The Sync App uses the system proxy settings by default, without further configuration needed. If you want to explicitly configure proxy exceptions for this connection, set ProxyAutoDetect to False.

This section provides a complete list of the Logging properties you can configure in the connection string for this provider.

---

Property	Description
LogModules	Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.

Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.

Remarks

The Sync App writes details about each operation it performs into the logfile specified by the Logfile connection property.

Each of these logged operations are assigned to a themed category called a module, and each module has a corresponding short code used to labels individual Sync App operations as belonging to that module.

When this connection property is set to a semicolon-separated list of module codes, only operations belonging to the specified modules are written to the logfile. Note that this only affects which operations are logged moving forward and doesn't retroactively alter the existing contents of the logfile. For example: INFO;EXEC;SSL;META;

By default, logged operations from all modules are included.

You can explicitly exclude a module by prefixing it with a "-". For example: -HTTP

To apply filters to submodules, identify them with the syntax <module name>.<submodule name>. For example, the following value causes the Sync App to only log actions belonging to the HTTP module, and further refines it to exclude actions belonging to the Res submodule of the HTTP module: HTTP;-HTTP.Res

Note that the logfile filtering triggered by the Verbosity connection property takes precedence over the filtering imposed by this connection property. This means that operations of a higher verbosity level than the level specified in the Verbosity connection property are not printed in the logfile, even if they belong to one of the modules specified in this connection property.

The available modules and submodules are:

This section provides a complete list of the Schema properties you can configure in the connection string for this provider.

---

Property	Description
Location	Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
BrowsableSchemas	Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
Tables	Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
Views	Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .

Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.

Remarks

The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is %APPDATA%\\CData\\SAPHanaXSA Data Provider\\Schema, where %APPDATA% is set to the user's configuration directory:

Platform	%APPDATA%
Windows	The value of the APPDATA environment variable
Linux	~/.config

Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .

Remarks

Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.

Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .

Remarks

Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.

If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.

Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .

Remarks

Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.

If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views. To do this, specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.

This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.

---

Property	Description
MaxRows	Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
ODataVersion	The version of OData to use. By default the provider will attempt to autodetect the version.
Other	Specifies advanced connection properties for specialized scenarios. Use this property only under the guidance of our Support team to address specific issues.
Pagesize	Specifies the maximum number of records per page the provider returns when requesting data from SAP HANA XSA.
ParametersEntitySets	The comma separated list of the renamed parameter entity sets for the exposed parameterized calculated views.
PseudoColumns	Specifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'.
SupportsExpand	Whether you need to specify the base entity's key to query navigation property views.
SupportsFormulas	A boolean indicating whether the OData service supports server side formulas.
Timeout	Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
UseClientSidePaging	Whether or not the CData ADO.NET Provider for SAP HANA XSA should use client side paging.
UseEtags	Whether or not the OData source uses Etags.
UserDefinedViews	Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file.
UseSimpleNames	Specifies whether or not simple names should be used for tables and columns.

Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.

Remarks

The default value for this property, -1, means that no row limit is enforced unless the query explicitly includes a LIMIT clause. (When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting.)

Setting MaxRows to a whole number greater than 0 ensures that queries do not return excessively large result sets by default.

This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.

The version of OData to use. By default the provider will attempt to autodetect the version.

Remarks

The version of OData to use. By default the Sync App will automatically attempt to determine the version the service is using. If a version cannot be resolved, 3.0 will be used. This can optionally be manually set.

Specifies advanced connection properties for specialized scenarios. Use this property only under the guidance of our Support team to address specific issues.

Remarks

This property allows advanced users to configure hidden properties for specialized situations, with the advice of our Support team. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. To define multiple properties, use a semicolon-separated list.

Note: It is strongly recommended to set these properties only when advised by the Support team to address specific scenarios or issues.

Integration and Formatting

Property	Description
DefaultColumnSize	Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000.
ConvertDateTimeToGMT=True	Converts date-time values to GMT, instead of the local time of the machine. The default value is False (use local time).
RecordToFile=filename	Records the underlying socket data transfer to the specified file.

Specifies the maximum number of records per page the provider returns when requesting data from SAP HANA XSA.

Remarks

When processing a query, instead of requesting all of the queried data at once from SAP HANA XSA, the Sync App can request the queried data in pieces called pages.

This connection property determines the maximum number of results that the Sync App requests per page.

Note: Setting large page sizes may improve overall query execution time, but doing so causes the Sync App to use more memory when executing queries and risks triggering a timeout.

The comma separated list of the renamed parameter entity sets for the exposed parameterized calculated views.

Remarks

You can provide the parameters entity set names as a comma separated list for the exposed calculated views that you are either using a renamed parameters entity set or a renamed Results navigation property.

Specifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'.

Remarks

This property allows you to define which pseudocolumns the Sync App exposes as table columns.

To specify individual pseudocolumns, use the following format:

Table1=Column1;Table1=Column2;Table2=Column3

To include all pseudocolumns for all tables use:

*=*

Whether you need to specify the base entity's key to query navigation property views.

Remarks

This connection property is primarily used with limited OData APIs; it determines whether navigation properties can be retrieved from the base entity set. In OData, navigation properties link a base entity to a related entity or a collection of related entities.

For more on navigation properties, see Data Model.

Working with Limited APIs

In OData, the $expand parameter is used to expand specified navigation properties when requesting data from a given entity set. In SQL, this makes it possible to execute a SELECT * to a navigation property view.

If $expand is not supported, a different request must be made to retrieve a navigation property, one that specifies the primary key of the base entity set. This API restriction is reflected in SQL: You will need to specify the base entity's primary key in the WHERE clause.

For example, consider two entities with a one-to-many relationship in the Northwind sample service, Categories and Products. In OData, the Products associated with a given Category could be represented as a navigation property on the base Category entity set. The Sync App models the Products navigation property as a Categories_Products view.

If $expand is not supported, use a query like the following to this view:

SELECT       * 
FROM         Categories_Products
WHERE        (Categories_CategoryID = 1)

A boolean indicating whether the OData service supports server side formulas.

Remarks

OData has many server-side formulas that are built into the specifications. However, many services do not natively support them and will return errors when these formulas are appended to the $filter parameter. When supported, server-side formulas can be used to execute certain queries much faster. If your OData service supports formulas, set this connection property to true. Otherwise, leave it as false.

Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.

Remarks

The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.

Timeout is set to 60 seconds by default. To disable timeouts, set this property to 0.

Disabling the timeout allows operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server.

Note: Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.

Whether or not the CData ADO.NET Provider for SAP HANA XSA should use client side paging.

Remarks

Some sources do not support server side paging. In these cases, set UseClientSidePaging to true. Otherwise, leave it as false. Setting UseClientSidePaging to true on a source that already supports paging can cause incomplete results.

Whether or not the OData source uses Etags.

Remarks

Some OData sources do not use Etags. In these instances, set UseEtags to False.

Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file.

Remarks

UserDefinedViews allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the Sync App and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view.

For example:

{
	"MyView": {
		"query": "SELECT * FROM SampleTable WHERE MyColumn = 'value'"
	},
	"MyView2": {
		"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
	}
}

You can use this property to define multiple views in a single file and specify the filepath. For example:

UserDefinedViews=C:\Path\To\UserDefinedViews.json

When you specify a view in UserDefinedViews, the Sync App only sees that view.

For further information, see User Defined Views.

Specifies whether or not simple names should be used for tables and columns.

Remarks

SAP HANA XSA tables can include special characters in their names that are typically not allowed in standard databases. This property makes the Sync App easier to use with traditional database tools.

Setting UseSimpleNames to True simplifies the names of the columns that are returned. It enforces a naming scheme where only alphanumeric characters and underscores are valid for displayed column names.

Notes:

• Any non-alphanumeric characters are converted to underscores.
• If the column or table names exceed 128 characters in length they are truncated to 128 characters to comply with SQL Server standards.

NSIS 3.10

Copyright (C) 1999-2025 Contributors THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.

1. DEFINITIONS

"Contribution" means:

a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and b) in the case of each subsequent Contributor:

i) changes to the Program, and

ii) additions to the Program;

where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.

"Contributor" means any person or entity that distributes the Program.

"Licensed Patents " mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.

"Program" means the Contributions distributed in accordance with this Agreement.

"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.

2. GRANT OF RIGHTS

a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.

b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.

c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.

d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.

3. REQUIREMENTS

A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:

a) it complies with the terms and conditions of this Agreement; and

b) its license agreement:

i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;

ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;

iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and

iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.

When the Program is made available in source code form:

a) it must be made available under this Agreement; and

b) a copy of this Agreement must be included with each copy of the Program.

Contributors may not remove or alter any copyright notices contained within the Program.

Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.

4. COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.

For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.

5. NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement, including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.

6. DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7. GENERAL

If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.

If Recipient institutes patent litigation against a Contributor with respect to a patent applicable to software (including a cross-claim or counterclaim in a lawsuit), then any patent licenses granted by that Contributor to such Recipient under this Agreement shall terminate as of the date such litigation is filed. In addition, if Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.

All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.

Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. IBM is the initial Agreement Steward. IBM may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.

This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.
