Transparent Gateway for VSAM: Customizing the Initialization Parameter File

The initialization parameter file must be available when the gateway is started. During installation, the following default initialization parameter file is created:

$ORACLE_HOME/tg4VSAM/admin/inittg4VSAM.ora

Where $ORACLE_HOME is the directory under which the gateway is installed.

If you are not using tg4VSAM as the gateway SID, you must rename the initialization parameter file using the SID you chose. This default initialization parameter file is sufficient for starting the gateway, verifying a successful installation, and running the demonstration scripts.

In the initialization parameter file, specify the VSAM connection as follows:

HS_FDS_CONNECT_INFO="address='host' port='port' workspace='workspace'"

Where:

• host: The name of the host compute
• port: The port number to listen to
• workspace: The VSAM data source workspace name (optional)

A number of initialization parameters can be used to modify the gateway behavior. You may want to change the initialization parameter file later to meet system requirements.
