CAS9 execution fails and issues the following message with no other explanation:
CAS9173E - ERRORS DETECTED DURING CAIRIM INITIALIZATION
As a result, no defined product initialization statements are processed as expected.
.
Release: Common Services-for z/OS r15.0
Component: CAIRIM
This is caused by the CAS9 procedure picking up an older module either from the linklist or steplib concatenation.
Ensure that CAW0LINK has been added to your Linklist ahead of any older Common Services load library; there are no older Common Services libraries, or libraries containing older Common Services modules concatenated ahead of the current Common Services loadlib in the Steplib of your CAS9 procedure.
