This page provides a guide to Establishing a Connection to Azure Data Catalog in CData Cloud, as well as information on the available resources, and a reference to the available connection properties.

Connecting to Azure Data Catalog

Establishing a Connection shows how to authenticate to Azure Data Catalog and configure any necessary connection properties to create a database in CData Cloud

Accessing Data from CData Cloud Services

Accessing data from Azure Data Catalog through the available standard services and CData Cloud administration is documented in further details in the CData Cloud Documentation.

Connect to Azure Data Catalog by selecting the corresponding icon in the Database tab. Required properties are listed under Settings. The Advanced tab lists connection properties that are not typically required.

Connecting to Azure Data Catalog

You can optionally set the following to read the different catalog data returned from Azure Data Catalog.

• CatalogName: Set this to the catalog name associated with your Azure Data Catalog. If left blank, the default catalogis is used.

  To get your catalog name, navigate to the Azure Portal home page > Data Catalog > Catalog Name

Authenticating to Azure Data Catalog

Entra ID (Azure AD)

Note: Microsoft has rebranded Azure AD as Entra ID. In topics that require the user to interact with the Entra ID Admin site, we use the same names Microsoft does. However, there are still CData connection properties whose names or values reference "Azure AD".

Microsoft Entra ID is a multi-tenant, cloud-based identity and access management platform. It supports OAuth-based authentication flows that enable the driver to access Azure Data Catalog endpoints securely.

Authentication to Entra ID via a web application always requires that you first create and register a custom OAuth application. This enables your application to define its own redirect URI, manage credential scope, and comply with organization-specific security policies.

For full instructions on how to create and register a custom OAuth application, see Creating an Entra ID (Azure AD) Application.

After setting AuthScheme to AzureAD, the steps to authenticate vary, depending on the environment. For details on how to connect from desktop applications, web-based workflows, or headless systems, see the following sections.

Azure Service Principal

Note: Microsoft has rebranded Azure AD as Entra ID. In topics that require the user to interact with the Entra ID Admin site, we use the same names Microsoft does. However, there are still CData connection properties whose names or values reference "Azure AD".

Azure Service Principal is role-based application-based authentication. This means that authentication is done per application, rather than per user. All tasks taken on by the application are executed without a default user context, but based on the assigned roles. The application access to the resources is controlled through the assigned roles' permissions.

For information about how to set up Azure Service Principal authentication, see Creating a Service Principal App in Entra ID (Azure AD).

Managed Service Identity (MSI)

If you are running Azure Data Catalog on an Azure VM and want to automatically obtain Managed Service Identity (MSI) credentials to connect, set AuthScheme to AzureMSI.

User-Managed Identities

To obtain a token for a managed identity, use the OAuthClientId property to specify the managed identity's client_id.

If your VM has multiple user-assigned managed identities, you must also specify OAuthClientId.

Customizing the SSL Configuration

By default, the Cloud 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 Cloud 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 Azure Data Catalog APIs.

Key Features

• The Cloud models Azure Data Catalog entities like custom data sources, data assets, and data asset annotations as relational views, allowing you to write SQL to query Azure Data Catalog data.
• Live connectivity to these objects means any changes to your Azure Data Catalog account are immediately reflected when using the Cloud.

Views

Views describes the available views. Views are statically defined to model Custom Data Sources, Data Assets, Data Asset Annotations, and more.

Views are similar to tables in the way that data is represented; however, views are read-only.

Queries can be executed against a view as if it were a normal table.

Identifies the Azure Data Catalog tenant being used to access data. Accepts either the tenant's domain name (for example, contoso.onmicrosoft.com ) or its directory (tenant) ID.

Data Type

string

Default Value

""

Remarks

A tenant is a digital container for your organization's users and resources, managed through Microsoft Entra ID (formerly Azure AD). Each tenant is associated with a unique directory ID, and often with a custom domain (for example, microsoft.com or contoso.onmicrosoft.com).

To find the directory (tenant) ID in the Microsoft Entra Admin Center, navigate to Microsoft Entra ID > Properties and copy the value labeled "Directory (tenant) ID".

This property is required in the following cases:

• When AuthScheme is set to AzureServicePrincipal or AzureServicePrincipalCert
• When AuthScheme is AzureAD and the user account belongs to multiple tenants

You can provide the tenant value in one of two formats:

• A domain name (for example, contoso.onmicrosoft.com)
• A directory (tenant) ID in GUID format (for example, c9d7b8e4-1234-4f90-bc1a-2a28e0f9e9e0)

Specifying the tenant explicitly ensures that the authentication request is routed to the correct directory, which is especially important when a user belongs to multiple tenants or when using service principal–based authentication.

If this value is omitted when required, authentication may fail or connect to the wrong tenant. This can result in errors such as unauthorized or resource not found.

Specifies the Azure network environment to which you will connect. Must be the same network to which your Azure account was added.

Possible Values

GLOBAL, CHINA, USGOVT, USGOVTDOD

Data Type

string

Default Value

"GLOBAL"

Remarks

Required if your Azure account is part of a different network than the Global network, such as China, USGOVT, or USGOVTDOD.

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.

Data Type

string

Default Value

""

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 Cloud 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.).

Data Type

string

Default Value

""

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.

Data Type

string

Default Value

""

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 JWT OAuth properties you can configure in the connection string for this provider.

---

Property	Description
OAuthJWTCert	Supplies the name of the client certificate's JWT Certificate store.
OAuthJWTCertType	Identifies the type of key store containing the JWT Certificate.
OAuthJWTCertPassword	Provides the password for the OAuth JWT certificate used to access a password-protected certificate store. If the certificate store does not require a password, leave this property blank.
OAuthJWTCertSubject	Identifies the subject of the OAuth JWT certificate used to locate a matching certificate in the store. Supports partial matches and the wildcard '*' to select the first certificate.

Supplies the name of the client certificate's JWT Certificate store.

Data Type

string

Default Value

""

Remarks

The OAuthJWTCertType field specifies the type of the certificate store specified in OAuthJWTCert. If the store is password-protected, use OAuthJWTCertPassword to supply the password..

OAuthJWTCert is used in conjunction with the OAuthJWTCertSubject field in order to specify client certificates. If OAuthJWTCert has a value, and OAuthJWTCertSubject is set, the CData Cloud initiates a search for a certificate. For further information, see OAuthJWTCertSubject.

Designations of certificate stores are platform-dependent.

Notes

• The most common User and Machine certificate stores in Windows include:
  • MY: A certificate store holding personal certificates with their associated private keys.
  • CA: Certifying authority certificates.
  • ROOT: Root certificates.
  • SPC: Software publisher certificates.
• In Java, the certificate store normally is a file containing certificates and optional private keys.
• When the certificate store type is PFXFile, this property must be set to the name of the file.
• When the type is PFXBlob, the property must be set to the binary contents of a PFX file (i.e. PKCS12 certificate store).

Identifies the type of key store containing the JWT Certificate.

Possible Values

PFXBLOB, JKSBLOB, PEMKEY_BLOB, PUBLIC_KEY_BLOB, SSHPUBLIC_KEY_BLOB, XMLBLOB, BCFKSBLOB

Data Type

string

Default Value

"PEMKEY_BLOB"

Remarks

BCFKSBLOB	A string (base-64-encoded) that contains a Bouncy Castle keystore.

Provides the password for the OAuth JWT certificate used to access a password-protected certificate store. If the certificate store does not require a password, leave this property blank.

Data Type

string

Default Value

""

Remarks

This property specifies the password needed to open a password-protected certificate store. To determine if a password is necessary, refer to the documentation or configuration for your specific certificate store.

Identifies the subject of the OAuth JWT certificate used to locate a matching certificate in the store. Supports partial matches and the wildcard '*' to select the first certificate.

Data Type

string

Default Value

"*"

Remarks

The value of this property is used to locate a matching certificate in the store. The search process works as follows:

• If an exact match for the subject is found, the corresponding certificate is selected.
• If no exact match is found, the store is searched for certificates whose subjects contain the property value.
• If no match is found, no certificate is selected.

You can set the value to '*' to automatically select the first certificate in the store. The certificate subject is a comma-separated list of distinguished name fields and values. For example: CN=www.server.com, OU=test, C=US, [email protected].

Common fields include:

Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

If a field value contains a comma, enclose it in quotes. For example: "O=ACME, Inc.".

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.

Data Type

string

Default Value

""

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 Logging properties you can configure in the connection string for this provider.

---

Property	Description
Verbosity	Specifies the verbosity level of the log file, which controls the amount of detail logged. Supported values range from 1 to 5.

Specifies the verbosity level of the log file, which controls the amount of detail logged. Supported values range from 1 to 5.

Data Type

string

Default Value

"1"

Remarks

This property defines the level of detail the Cloud includes in the log file. Higher verbosity levels increase the detail of the logged information, but may also result in larger log files and slower performance due to the additional data being captured.

The default verbosity level is 1, which is recommended for regular operation. Higher verbosity levels are primarily intended for debugging purposes. For more information on each level, refer to Logging.

When combined with the LogModules property, Verbosity can refine logging to specific categories of information.

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

---

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

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

Data Type

string

Default Value

""

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.

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.
Pagesize	Specifies the maximum number of records per page the provider returns when requesting data from Azure Data Catalog.
PseudoColumns	Specifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'.
ThrowsKeyNotFound	Specifies whether or not throws an exception if there is no rows updated.
Timeout	Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.

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

Data Type

int

Default Value

-1

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.

Specifies the maximum number of records per page the provider returns when requesting data from Azure Data Catalog.

Data Type

int

Default Value

100

Remarks

When processing a query, instead of requesting all of the queried data at once from Azure Data Catalog, the Cloud can request the queried data in pieces called pages.

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

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

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

Data Type

string

Default Value

""

Remarks

This property allows you to define which pseudocolumns the Cloud 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:

*=*

Specifies whether or not throws an exception if there is no rows updated.

Data Type

bool

Default Value

false

Remarks

Specifies whether or not throws an exception if there is no rows updated.

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

Data Type

int

Default Value

60

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.

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.
