Error description

  • DB2DDF DB2TCPIP DB2DRDA defect pm64376 dpm64376
DB2 10 for z/os abend 04E-00E2000C may be seen for various DDF
modules due to the storage pool "ADMF SHARED ATB POOL"
reaching its max size. The pool will contain numerous control
SPME control blocks.

04E-00E2000C LOC=DSNLIRTR.DSNSVSVB+0AC2
04E-00E2000C LOC=DSNLTACC.DSNSVSVB+0AC2
04E-00E2000C LOC=DSNLILNR.DSNSVSVB+0AC2

The system profiling function does not have to be
active to see the accumulating SPME blocks.

****************************************************************
When remote client applications connect to a DB2 10 for z/OS
server via TCP/IP, new System Profile Monitoring (SPM) support
in DB2 10 for z/OS monitors events related to the different
remote client applications that access DB2, even if SPM is not
enabled.  If the behavior or processing of the remote
applications are such that unique (monitored) values are always
encountered, storage (SPME control blocks) utilization
accumulates over time which can eventually lead to 04E-00E2000C
abend conditions.
The entire DB2 subsystem must be stopped and restarted to
relieve the storage condition.
The unique SPM (monitored) values that are typically observed
include:
o End Client UserID.
o End Client Application Name.
o End Client Workstation Name.
o Collection ID.
o Package name.

Problem conclusion

  • DB2 10 for z/OS server processing has been changed to reuse the
available DB2 (SPME) control blocks when they no longer reflect
active usage.
