To upgrade from Datacom/AD 15.0 to 15.1 , first install the Datacom/AD 15.1 software , install all published Datacom maintenance and then perform an Active MUF Upgrade from 15.0 to 15.1.
The process of upgrading the Datacom Datadictionary Version to 15.0 must have been completed before performing a 15.0 to 15.1 active MUF upgrade.
The 15.0 Datacom/AD Multi-User Facility (MUF) should show these messages during startup:
DB00915I - CXX DBID 2 DATA-DICT DEFINITION VERSION 15.0 CHANGE LEVEL 0
DB00915I - CXX DBID 15 DDD-DATABASE DEFINITION VERSION 15.0 CHANGE LEVEL 0
In some Datacom/AD MUFs , above messages are not displayed . To check if Datadictionary is version 15.0 , run a DBUTLTY CXX report with SYSIN card REPORT AREA=CXX,DBID=002.
Look at the report and make sure TABLE NAME - DOC ( OCCURRENCE - DOCUMENT) is found.
z/OS
Datacom/AD 15.1
After the upgrade to version 15.1 the MUF startup still shows version 15.0 in the DB00915I messages since there is no base upgrade for DATA-DICT or DDD-DATABASE when upgrading from version 15.0 to 15.1.
Note that the DB00915I message for CASYSTEMTABLES can show 14.0 or 15.0 ( not 15.1).
