Error description

  • DB2DDF Defect pm95754 dpm95754
    An ABEND04E with RC00E2000C from DSNSVSVB can happen if High
    Perf DBATs are enabled
    04E-00E2000C,LOC=DSNLIRTR.DSNSVSVB+0AA
    
    The 04E-00E2000C abends may also be seen for various DDF modules
    if one of these conditions are true:
    -The thread is a High Performance DBAT
    -The thread is associated with Keep Dynamic packages
    -The thread has serviced accelerated queries

Local fix

  • no local workaround
    
    A recycle of DB2 is required to free the storage accumulated
    when abend 00E2000C is reached.

    ****************************************************************
    When remote client applications connect to a DB2 for z/OS (V10
    or higher) server via TCP/IP, System Profile Monitoring (SPM)
    support monitors events related to the different remote client
    applications that access DB2, even if SPM is not enabled.  The
    storage acquired on behalf of monitoring these events (SPME
    control blocks) can be reused when the storage no longer
    reflects any active usage.  However, the active usage is not
    properly maintained in the following cases:
     o The thread is a High Performance DBAT.
     o The thread is associated with Keep Dynamic packages.
     o The thread has serviced accelerated queries.
    The erroneous active usage information prevents the storage
    from being reused to monitor other events.  This leads to an
    accumulation of storage in the 'SPM SHARED ATB POOL' storage
    pool.  Over time, this accumulation can eventually lead to
    various short on storage related abend symptoms such as
    04E-00E2000C.
    

Problem conclusion

  • DB2 for z/OS server processing has been changed to correctly
    reflect its SPM related storage usage.
    

Temporary fix

  • *********
    * HIPER *
    *********
    A RECYCLE OF DB2 IS REQUIRED WHEN ABENDS WITH REASON=00E2000C
    HAVE OCCURRED.
