APAR status

• Closed as program error.

Error description

• Customer is running a batch CSL job to quiesce DB's is recieving
  a S0C4 caused by an overlay of the consolidated response buffer
  that is passed back to the master IMS.
  Since the buffer is released by the time of the abend it has not
  been determined when the overlay occurs.

  * PROBLEM DESCRIPTION:                                         *
  * Message overlay as passed through XCF. Externally ABEND0C4   *

  ****************************************************************
  When SCI XCF Message Out Services is given data in two buffers
  to send through XCF and the message is too large to send as one
  message, it breaks the message up on the sending side and
  reassembles it on the receiving side.
  
  When SCI breaks up the message and builds the buffer to send
  through XCF, if data from the second buffer is included in the
  buffer, the pointer in the second buffer is not adjusted after
  the data is moved to the buffer.  When SCI sends the rest of the
  data from the second buffer, it resends the first part of the
  buffer.  This data then overlays the buffer on the receiving
  side when it is reassembled.
  
  This overlay will cause unpredictable results, most often
  ABEND0C4.
  

Problem conclusion

•     Modules Changed
  
      ===============
  
  
  
      CSLSXCO0
  
        Added the code to adjust the second buffer's pointer for
  the case that
        a piece of the second buffer's message is sent with the
  message in the
        first buffer.
