> # Configuring a SequeLink® Service for Oracle

> The default for SequeLink Server for Oracle is to use the Oracle Bequeath protocol to communicate to the Oracle database engine. However, we strongly recommend that during installation, you select the Oracle Net Service instead. If you accept the default driver during installation and later want to use the TCP or IPC protocol through Oracle Net Service, you can change the configuration.

> To use the Oracle Net Service:

> 1. Configure the Oracle listener for Net Service (refer to your Oracle documentation for instructions).
> 2. Configure the SequeLink Oracle service to use the Oracle Net Service. Using the SequeLink Manager, add the SequeLink service attribute ServiceEnvironmentVariable to your SequeLink Oracle service:
> - On Windows, set the value to ServiceEnvironmentVariable=LOCAL=NetServiceName where NetServiceName is the Oracle Net service name you configured in Step 1.
> - On UNIX, set the value to ServiceEnvironmentVariable=TWO_TASK=NetServiceName where NetServiceName is the Oracle Net service name you configured in Step 1.
> 3. If the SequeLink service attribute ServiceEnvironmentVariable=ORACLE_SID=OracleSid exists for this SequeLink service, delete it.
> 4. Restart the SequeLink Oracle service.
