Establishing a Connection

Configure a Connection Profile

From the CData ribbon, click Get Data and select From Oracle OCI connection/s to launch the CData Query window. To setup a new connection, you will have to click the New Oracle OCI Connection button. Here you can set the connection settings, test the connection, and save the connection profile.

Connecting to Oracle OCI

Oracle OCI supports the following connection types:

Oracle Server
OracleTNS
LDAP

Oracle Server

After you have added the appropriate libraries to your PATH (as described in Before You Connect), set these properties:

User: The user Id provided for authentication with the Oracle database.
Password: The password provided for authentication with the Oracle database.
Port: The port used to connect to the server hosting the Oracle database.
ServiceName: The service name of the Oracle database. You can obtain this value by querying global_name (select * from global_name) using the Oracle SQL*PLUS command line.
Server: The host name or IP address of the server hosting the Oracle database.

OracleTNS

To authenticate via OracleTNS, set these properties:

User: The user Id provided for authentication with the Oracle database.
Password: The password provided for authentication with the Oracle database.
DataSource: The Oracle Net Services Name, Connect Descriptor (known also as TNS Connect String), or a connection name that identifies the database to which to connect. You should be able to find these values in your tnsnames.ora file.

For example,

DataSource='(DESCRIPTION=(ADDRESS=(protocol_address_information))(CONNECT_DATA= (SERVICE_NAME=service_name)))'

LDAP

To authenticate via the LDAP server, set these properties:

User: The user Id provided for authentication with the Oracle database.
Password: The password provided for authentication with the Oracle database.
LDAPUri: The LDAP URI used to connect to the LDAP server.
LDAPUser: The User account for LDAP server.
LDAPPassword: The password for the LDAP user.

Your connection string should look similar to this:

LDAPUri=ldap://myldap.com:389/SERVICE_EXMPL,cn=OracleContext,dc=example,dc=com; User=ORACLEUSER; Password=OracleUserPassword;

Note that this connection type requires both your Oracle and LDAP usernames and passwords. If your system administrator allows anonymous LDAP logins, your LDAP username and password are not needed.

Connection Properties

The Connection properties describe the various options that can be used to establish a connection.

Managing Connections

After successfully authenticating to Oracle OCI you will be able to customize the data you are importing. To learn more about this, see Managing Connections.
