Error description

  • Multiple ABDUMP commands are entered for a BMP within the same
    second.  This results in the scheduling of 2 SRB to request
    termination of the BMP.  The first ABDUMP request is in progress
    and releasing storage areas when the second request begins.  The
    second request can encounter an ABEND0C4 if a required storage
    area has been previously released.  In the reported case, the
    released storage was the DFSECP pointed to by the TCB's first
    SAVEAREA in R1.
    .
    BMP/IFP regions do not check the SAPSABPR flag.  If SAPSABPR
    would have been checked, a MSGDFS0559I would have resulted:
    .
    DFS0559I ABEND ALREADY SCHEDULED FOR REGION
    

Local fix

  • Do not issue multiple ABDUMP commands for a BMP region.

    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    /STOP REG x ABDUMP is entered and in the process of terminating
    a dependent region when a second /STOP REGION x ABDUMP command
    is entered against the same region, most likely from an AOI due
    to the rapid succession of the commands.
    
    The first command processes far enough to free IMS storage
    when the second command attempts to use the same storage.
    ABEND0C4 results.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    Code was added to module DFSSTOP0 (/STO REG command processor)
    to detect that a /STO REGION x ABDUMP command is already in
    progress. DFS559 ABEND ALREADY SCHEDULED FOR REGION x is now
    issued when a prior /STOP REGION ABDUMP command is in progress.
