Error description

  • ABEND0C4-011 in module DFSDBAU0 + x'2D46' in CSECT OLICCALL.
    We fail on instruction: x'5877000C' "THE BIG DB DDIR" because
    of a bad Reg7. Reg7 has been loaded a few instructions before
    from Reg8+X'68'. At that time, R8=00000000 and normally should
    contain the address of the DDIR (from PSTWRK1).
    This problem is a consequence of a DFSUICP0 BMP started for a
    never accessed and stopped HALDB database (DDIRNOSC on).

Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of IMS V11 Online Image Copy utility   *
    *                 (DFSUICP0) and HALDB databases are affected. *
    ****************************************************************
    * PROBLEM DESCRIPTION: User received an AbendS0C4 in the       *
    *                      control region when trying to run       *
    *                      Online Image copy (OLIC) on a HALDB     *
    *                      database that was stopped.              *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    Online Image Copy utility should be run on databases that are
    started.  If a HALDB is stopped or /DBR'd, running Online
    Image Copy utility resulted in an AbendS0C4 in the control
    region.  The abend is caused by the DDIR control block of the
    partition database containing a zero DMB address (DDIRADDR)
    at offset x10.  When this field is then used to set up the
    DSG control block at label OKDCBNO in module DFSUICC0,
    garbage data are filled into the DSG block.
    Later at label KPOLICCD, the bad DSG block is passed to the
    authorization module DFSDBAU0 and results in an AbendS0C4 in
    the control region.
    
    The Online Image Copy utility should not cause an abend in the
    control region if the HALDB database is not started.
    Module DFSUICC0 should check the validity of the DDIR control
    block, make sure the database is started, before authorizing
    and copying the database.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    Module DFSUICC0 has been updated to resolve the abend.
    Code has been added to verify the master database does not
    have the DDIRNOSC bit on (DB not scheduled), and the partition
    database does not have a zero DMB address, before calling the
    authorization module.
    
    If either condition is met, the Online Image Copy utility will
    terminate with a return code of 8 and the message:
    DFS3339A   DATA BASE AUTHORIZATION FAILURE  CODE - 4
