Before you begin upgrading your DB2® configuration, ensure that you have read
and followed the instructions in, "Prepare your CICS® IA configuration environment". Also,
review "DB2(r) considerations".
There are two methods to upgrade the DB2 tables:
Copy the previous CICS IA DB2 tables
to a new database
If you choose to use this method, you
must first create a new CICS IA DB2 database and then use DB2 utilities to UNLOAD from the
previous database and LOAD into the new database.
Upgrade the previous CICS IA DB2 database to the new structure
If
you choose this method, you update only the tables that have a different
structure from the tables in your previous CICS IA version. This method is a single database
migration method.
Note: CICS IA
V5.2 does not provide jobs to port your existing collector VSAM files.
You must load all your VSAM data in to your existing DB2 tables before you proceed with the DB2 upgrade. CICS IA V5.2 does not provide upgrade jobs for
the Command Flow data.
