Hi,

Reference tables for an application is stored in VSAM as CDT tables in CICS. There is a plan to move this data into DB2 tables.Any inputs on the performance implications due to this? I just wanted to get a highlevel PROS and CONS of doing this.I appreciate your inputs on this.Thanks.

manu,

CDT tables are nothing but VSAM files. So you are converting a VSAM file to a DB2 Table.

So you need to take a 2 step process and first migrate the data to DB2 table and then rewrite the application to read/write the data from DB2 table.

IBM has a product named "CICS VSAM Transparency for z/OS Version" which you can give it a try.
