Problem:
Ran CAIRIM to install the PC routines for CA Datacom/AD 14.0 on the LPAR where MSMCPROC runs but it still fails with
DB01801E - INTERFACE ERROR - 44

Environment:
z/OS, SCS address space, MSMMUF

Cause:
There are two PC routines for CA Datacom/AD 14.0, DBPCCPR and DBPCSPR.  DBPCSPR is used for Cross-System Coupling Facility (XCF)
which involves communication between an application such as MSMCPROC making database request from one LPAR to MSMMUF on another
LPAR. Without DBPCSPR MSMCPROC will fail with code 44.

Resolution/Workaround:
Run DBUTLTY with REPORT MEMORY=MVS to verify that DBPCSPR was installed by CAIRIM. If it was not installed rerun CAIRIM with:
//RIMPC.PARMLIB DD *
PRODUCT(CA DATACOM) VERSION(BD14) INIT(DBCR4PR)
LOADLIB(hlq.CAAXLOAD)
PARM(PC=PROD,PCC=DBPCCPR)
PRODUCT(CA DATACOM) VERSION(BD14) INIT(DBCR4PR)
LOADLIB(hlq.CAAXLOAD)
PARM(PC=PROD,PCS=DBPCSPR)
