Error description

  • The PSW points to module DFSCFEZ0+1560. The instruction
    is x'4440 8000' EX R4,LASTMOVE. We are executing the
    following instruction x'D200 2000 7000'.
    We are attempting to move 100 bytes from the storage at R7
    to the storage at R2. DFSYCLH0 called FEZ1-9181 to log a 6701
    logrecord. It sets up a parmlist that is passed to DFSCFEZ0 to
    log the 6701 log record. The parmlist is passed in Reg6.
    We abend due to the length of the user data being more
    then the total data, in this case TMAMAPP is x'199'. There is
    currently no check to determine if the address of
    TMAMAPP+TMAMALEN is greater than AWOCBUFA+Area_length.
    
    The savearea flow leading up to the abend was:
    DFSYTIB0-DFSYSND0-DFSYCLH0-FEZ1-9181-DFSTIME0 (returned)
    

Local fix

  • This can be corrected in the IMS Connect User Message Exit, if
    it is in use, by not sending the bad message at all.
