CICS VSAM Transparency for z/OS, Version 1.2


Establishing when exits are required

CICS® VT does not provide any facility to help you identify where exits are required. It is a manual process that needs detailed knowledge of the file, coupled with CICS VT experience. In some cases, application knowledge is essential, especially if data cleansing is required.

Because CICS VT experience is a factor of your own usage of the product, where possible you should start by migrating simple files. Initially, avoid files that need FBEs and IRDs to migrate to multiple tables. You should also try to avoid files that require SQL in an exit.
