CICS VSAM Transparency for z/OS, Version 1.2


The data migration component

CICS® VT is a suite of tools that cover the entire VSAM to DB2® migration process, including the key component of data migration. To migrate data from a VSAM file to a DB2 table, you must run a series of CICS VT batch utility jobs.

Some of these batch jobs use utilities provided with CICS VT and some use standard DB2 utilities such as LOAD, RUNSTATS, and REORG. In addition, you can use the DSNTIAUL DB2 sample program to generate the DB2 LOAD control cards.

When you are migrating the data, CICS VT automatically performs data re-engineering, according to how you have mapped the file. For example, if you have a field containing date information and you map this field to a DB2 DATE column, the data migration process builds the appropriate DB2 column values so that the data presented to the DB2 LOAD utility is correct.

An automated data migration facility generates the JCL and control cards for the each migration step.
