Error description

  • Error Description￘
    After upgrading to CICS TS 4.2. during shutdown you get
    message  DFHFC0002 A severe error (code X'0435') has occurred
    in module DFHFCST (base).  What is happening is DFHFCST, File
    Control Statistics Program, is collecting statistics for the
    LSRPOOL's.  It is going through all 255 LSRPOOLs.  When it gets
    to POOL_ID(FF) it is getting an error of
    SHRCTL_BLOCK_NOT_FOUND.
      In the CICS internal trace table you see:
    AP 0430 FCST ENTRY - FUNCTION(COLLECT_POOL_STATISTICS)
    POOL_ID(FF)
    AP 0435 FCST *EXC* - DISASTER DETECTED
    FUNCTION(COLLECT_POOL_STATISTICS)
          REASON(SHRCTL_BLOCK_NOT_FOUND)
    
      Prior to CICS TS 4.2 CICS only used LSRPOOLs 1-9, now at CICS
    TS 4.2 CICS may use all 255 LSRPOOLS.

    ****************************************************************
    A program is run within CICS which accesses a file using an
    LSRPOOL, but it does so without using CICS File Control.  CICS
    is then shutdown, during which DFHFCST is driven to gather
    statistics on all LSRPOOLs.  DFHFCST checks for a VSAM Shared
    Resource Table (VSRT) for each LSRPOOL ID.  The LSRPOOL used by
    the program has been built, so the VSRT pointer is non-zero.
    Procesing continues and DFHFCST attempts to establish
    addressability to the SHRCTL block for this LSRPOOL.  However as
    CICS File Control has not used this LSRPOOL the block doesn't
    exist and a disaster response is returned.  This escalates and
    the error message is issued despite the fact that no erroneous
    events have occurred.

Problem conclusion

  • DFHFCST has been modified so that in the previously described
    scenario a new exception type is returned.  No action is taken
    based on this response and therefore no error message is issued.
