Error description

  • The following abend occurred on page set close.
    DSN ,ABND=0C4-00000004,U=uuuuuuu ,M=N  ,C=101.BMC
     -DSNB1ABO,M=DSNTFRCV,LOC=DSNIDM  .DSNB1ABO+02E4
                                                                   .
    The abend occurred as the bbry and bbtr were already freed.
    It looks like dsnidalc may have freed the blocks too soon.
                                                                   .

    * PROBLEM DESCRIPTION: ABND=0C4-00000004 at DSNB1ABO+2E4       *
    *                      during agent de-allocation process.     *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When de-allocating an agent, DB2 freed an internal control
    block that's needed for its page set logical close process.
    This caused the ABND=0C4-00000004 at DSNB1ABO+2E4.
    

Problem conclusion

  • Fixes made in DB2 to close the page set first before freeing
    its internal control block that's still needed in its page
    set close process.
