Question:

If you create a library (PDSE) for the TSS CAILOAD (TSS r14.0) or TSS CAKOLINK (TSS r15.0), at IPL time, you will receive.

TSS TSS - ABEND=S000 U0012 REASON=00000000.
CAS9023E - CAISSF INITIALIZATION ERROR - ROUTINES MISSING OR ALREADY PRESENT
CAS9140E - INIT ERROR: CAISSF VER S910, INIT ROUTINE RC=0008

Answer:

This problem can happen when you install Top Secret with MSM.

When you choose to install TSS with CSM, ituses LIBRARY by default.

Specify PDS instead so the abend doesn't occur.
