CICS VSAM Transparency for z/OS, Version 1.2


Installing the batch subsystem

CICS® VT intercepts VSAM calls in your application batch programs using an MVS™ subsystem interface (SSI). The SSI can be installed dynamically if you are running OS/390® V2.4 or any later level. If you do not have OS/390 V2.4, you have to IPL to complete the SSI installation. Updates to your SYS1.PARMLIB data set are required to install the subsystem permanently.

Installing the subsystem, whether dynamically or permanently, does not mean that all VSAM requests are intercepted and processed by CICS VT. This only occurs when the appropriate JCL changes are made.
