CICS VSAM Transparency for z/OS, Version 1.2


Managing the CICS VT control tables

The CICS® VT control tables are used during mapping and for generating the CICS VT driver modules. When all of your VSAM data sets have been migrated to DB2® , the CICS VT control tables are no longer used unless you want to update mapping information.

Ensure that you have a policy in place to manage backup and recovery of these critical CICS VT components. You need to pay particular attention to the VID_SRC table. The data in this table is transient and is created and used when you generate CICS VT driver modules. After the drivers are generated, the data is no longer required.
