When using XCF to communicate to the Datacom Multi-User (MUF) environment, the current Datacom version of the CA Datacom PC Call routine (DBPCCPR) must have been loaded with CAS9/CAIRIM on each of those LPARs.
In one case, CA-11 from a remote LPAR would not react to the 'O' response to this prompt:
U11D-0230-2 SUBSYSTEM CAL7 ALREADY ACTIVE; REPLY 'O' TO OVERRIDE OR 'A' TO ABORT DBAS INITIALIZATION
12.51.19 STC06904 IEF403I CAL7 - STARTED - TIME=12.51.19

Release : 15.0
Component : CA Datacom/AD
Release : 11.0
CA Workload Automation Restart Option for z/OS Schedulers - 11.0 CA 11
It was determined that the CA Datacom 15.0 DBPCCPR had not loaded by CAS9 at the IPL because the CAIRIM parms for Datacom Version 15.0 has not been provided.
Once CAIRIM was run to load it (CA Datacom/AD 15.0 INSTJCL job AXRIM01) and CAS9 CAIRIM parms updated to next IPL on this LPAR, the CA-11 reply 'O' was acknowledged and the remote CA-11 connected to the MUF and started successfully.
