Error description

  • DFHSM0002 A severe error (code X'030F') has occurred in module
DFHSMGF.
This is due to a double freemain of the RMOFRMLK during a
BACKOUT processing. The CICS RM Resource Manager calls DFHCR2U
PERFORM_COMMIT for the APPC session to IMS which fails because
the conversation with the remote region has been lost.
This the same problem reported in the apar PM68598 and PI48952

* PROBLEM DESCRIPTION: Message DFHSM0002 with code X'030F' is  *
*                      issued after message DFHRM0107 reports  *
*                      an intersystem communication failure.   *

* RECOMMENDATION:                                              *
****************************************************************
IMS used an LU6.2 connection to start a task in a CICS TOR that
was then transaction routed to a CICS AOR. The TOR getmained a
RMOFRMLK control block for the LU6.2 connection.
The task in the AOR issued a SYNCPOINT ROLLBACK.
Backout processing failed in the TOR because the IMS connection
was lost. The connection was re-established and a new RMOFRMLK
getmained.
As part of Recovery Manager TERMINATE_RECOVERY processing, the
original RMOFRMLK was freemained.
At task termination on the TOR, an attempt was made to freemain
the original RMOFRMLK rather than the replacement.

Problem conclusion

  • The Recovery Manager TERMINATE_RECOVERY code has been changed
to reflect the freemain of the original RMOFRMLK.
When task termination occurs the replacement RMOFRMLK is
freemained.
