Problem summary

  • ****************************************************************
    * USERS AFFECTED: All IMS V13 users using REXX SPOC API        *
    ****************************************************************
    * PROBLEM DESCRIPTION: IMS REXX SPOC API function CSLULGTP     *
    *                      goes into a 100% CPU loop if the OM     *
    *                      task is missing.                        *
    ****************************************************************
    * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
    ****************************************************************
    The IMS REXX SPOC API function CSLULGTP() - Retrieve command
    responses directly to REXX stem variables - goes into a loop
    if the OM task is missing because of a logic error in module
    CSLULFM1.
    
    CSLULFM1 calls an internal procedure within a loop.  When OM
    is missing the procedure returns with RC=8.
    
    In this situation CSLULFM1 does not set the required controls
    to exit the loop and begins looping forever.
    

Problem conclusion

  • GEN:
    KEYWORDS:
    
    *** END IMS KEYWORDS ***
    The following part was updated:
    
      CSLULFM1
    
    The CSLULFM1 routine was modified to set the proper controls
    when a non-zero RC is received from internal procedure calls
    to prevent the endless loop.
    

Temporary fix

  • The fix for this APAR is BAD.  If you need to apply
    the fix for this APAR to resolve a problem, you must
    also apply the fix for APAR PM79775.
