How to verify the PTF level of CA Datacom Program Call Module DBPCCPR?
After applying maintenance to module DBPCCPR, CAIRIM must be run for the new version of the code to take effect. Refer to CA Datacom/DB job BDRIM01 or CA Datacom/AD job AXRIM01.
To verify that the execution of CAIRIM has placed the updated DBPCCPR into effect, the CA Datacom DBUTLTY REPORT MEMORY=MVS report function can be run before and after the CAIRIM execution to compare the assembly date of DBPCCPR between the two runs. The post-CAIRIM execution should have a later assembly date.
Example partial MEMORY=MVS report output:
CA DATACOM/DB SUBSYSTEM IS PRESENT
COMMON MEMORY USAGE (NOT SVC OR MUF SPECIFIC)
ADDRESS SIZE TEXT
38567000 7710 DBPCCPR 15.0 20160712 14.21 CROSS MEMORY PC=PROD
In the above example, DBPCCPR 15.0 at 20160712 14.21 is via PTF RO89818.
There is no need to cycle the Datacom Multi-User (MUF). Any executing code in the old DBPCCPR continue executing in the old one but the next call is done in the new.
