Error description

  • Customer issued a /STO REG JOBNAME xxxxxx ABDUMP command against
    an MPP region which was in the middle of scheduling process.
    DFSASK00->DBFCPY00->DFSCBTS DDIR,OPTION=NOSER->DFSSCBT0->
    DFSSBLK0. DFSSBLK0 obtains the BLKM latch unconditionally,
    and this latch is not recoverable. To prevent U0780, ABDUMP
    command must be defered if this latch is held. IMS needs to
    set issue a DFSXMWIN ABDUMP_SYNC around this process to defer
    U0474 abend until latch has been released.
    

Local fix

  • Don't issue ABDUMP command against a region in process of
    scheduling.
