Load of Datacom PC call routines via CAIRIM (like in Datacom/AD 14.0 AXRIM01 or Datacom/DB 14.0 BDRIM01 installation jobs) fails and CAIRIM returns the following error messages:
DB90155E - ERROR DEFINE RETCODE -040 RSNCODE 632
DB90152E - DATACOM PARM SYNTAX ERROR (D)
DB90153E - DATACOM INITIALIZATION FAILED
Starting with Datacom 14.0, MUF no longer uses SVC to communicate, replaced by PC calls. Like the SVC, the PC routines need to be loaded by CAIRIM but their installation requires to activate the CA Master component of CA Common Service before running AXRIM01 or BDRIM01.
CA Master component is available starting from release 12.0 of CA Common Service (see informational APAR RI18890 for 12.0).
Additional details about CA Master component can be found on Chapter 13 of CA Common Services for z/OS Reference Guide manual (page 687 of 14.0 PDF manual, page 719 of 14.1 PDF manual)
