A job (MYDBJOB1), executing a Datacom utility or a user application, runs on the same LPAR (SYS1) where the Datacom MUF is currently active but, based on the DB00133I message:
DB00133I - JOB OPEN MYDBJOB1 15688 USER01 JOB12345 XCF-SYS1
the connection between the two address spaces occurs via XCF
Why does the connection between MYDBJOB1 and the Datacom Multiuser region occur in XCF mode and not locally?
DBSYSID macro has been assembled with: CONNECT_ALLOW_PRIORITY=(XCF,LOCAL) so XCF is the preferred connection method, even if the MUF and the job are running on the same LPAR.
DBSYSID must be changed to read:
and then DBSIDPR must be reassembled and relinked .
XCF is an added overhead and less efficient than LOCAL connection when both the job and the MUF are running on the same LPAR.
