By default, when you install the CA Intertest r 10 PAX installation file you will be installing four products CA Intertest CICS, CA Intertest batch, CA Symdump CICS and CA Symdump batch v 10 based on the FMID you choose to install. With the r 10 install you now have one load library(CAVHLOAD) that contains most of the load modules and a library that contains the APF authorization load modules(CAVHAUTH). The new v 10 multiple product install feature of v10 eliminates the duplicate FMIDS that are shipped with all four products and make the install -maintenance process quicker for many of our clients that use all four products.
There is no requirement that if you Install CA Intertest CICS r 10 applying just the CA Intertest CICS r 10 FMIDS that you cannot run CA Intertest batch r 9.1 on the same system. But with this configuration you would have to add the r 10 CAVHLOAD to the LINKLIST first followed by the CA Intertest batch r 9.1 CAVHLOAD and CAMRLOAD. This is because both of the CAVHLOAD load libraries contain the CA Intertest post processing programs for example IN25COB2 used to post processing you compile output. The latest post processor programs from the latest release should always be used.
