16 Migration From Previous Releases

This chapter describes how to migrate to new instances of Oracle Database Gateway for DRDA from an existing installation. Perform the following steps to migrate to a new release of Oracle Database Gateway for DRDA from an existing release:

  1. Install the New Release

  2. Gateway Initialization Parameter File

  3. Bind Gateway Package

  4. Install/Upgrade Data Dictionary Views

16.1 Install the New Release

Install the new release of the gateway in a separate directory, as discussed Chapter 12, "Installing Oracle Database Gateway for DRDA".

Caution:

Do not install the gateway over a previously existing gateway installation. This corrupts the existing installation.

16.2 Gateway Initialization Parameter File

This release of Database Gateway for DRDA has a completely new architecture. Most of the prior parameters are obsolete. You should not use the old initialization file as a base and try to modify it. Instead, you should use the new initialization generated as part of installation as a base. Refer to Appendix C, "Initialization Parameters" for the syntax of the parameters.

Existing TG4DB2 customer migrating to this release of Database Gateway for DRDA would need to provide the recovery user's password HS_FDS_RECOVERY_PWD, with this release of gateway.

16.3 Bind Gateway Package

The binding of the package is automatic. Refer to Chapter 13, "Configuring the DRDA Server".

16.4 Install/Upgrade Data Dictionary Views

You must install or upgrade the data dictionary views when upgrading the Oracle Database Gateway for DRDA. Refer to Chapter 14, "Configuring Oracle Database Gateway for DRDA" for more information on creating data dictionary views.
