CICS VSAM Transparency for z/OS, Version 1.2


Step 6 - Create dummy VSAM cluster

Create a dummy VSAM data set for each migrated file. This is described in detail in Additional DD statement for dummy VSAM data set. Depending on the nature of the target system, you might want to gather some performance data from your DB2 system before cutover. After cutover, gather the same data and compare results. This will help you to tune your DB2 system to ensure that performance levels are not degraded. Pay particular attention to EDM and buffer pool statistics.
