Error description

  • 'DISPLAY ACTIVE TERMINATED WITH MAX LINES' message was not
    issued  at the last line of CSQV402I as a result of the command
    'DISPLAY THREAD(*)' even if the number of lines  should have
    exceeded the max(252 dec.).
    
    The number of lines of output of dis thr(*) should have
    exceeded 251,but it does not indeed even the number of active
    threads is greater than the threshold.
    Therefore,expected message'DISPLAY ACTIVE TERMINATED
     WITH MAXLINES' is never issued as a result of the command
    'DISPLAY THREAD(*)' even though the number of "real" lines
    exceeds the max(252).
    
    For MQ version 8,the output of dis thr(*) displays 2 lines for
    1  active thread and looks like below  :
    
    NAME     S T   REQ THREAD-XREF              USERID   ASID
    
    RTPLCHIN T S     3                          MQMTASK  00CD
    
             URID=0000000000000000
    RTPLCHIN T S 19712                          MQMTASK  00CD
    
             URID=0000000000000000
    
    When the number of acive threads exceeds 125,the issue can be
    recreated successfully.
    The number of lines of output of dis thr(*) should have
    exceeded  251,but it does not indeed.

    * PROBLEM DESCRIPTION:                                         *
    * The output of the command DISPLAY THREAD(*) on the operator  *
    * console does not indicate that the limit of text lines has   *
    * been exceeded. This results in not all active threads are    *
    * displayed. The message DISPLAY ACTIVE REPORT COMPLETE is     *
    * issued instead of DISPLAY ACTIVE TERMINATED WITH MAX LINES.  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    * N/A                                                          *
    ****************************************************************
    The command processor for DISPLAY THREAD(*) does not count the
    number of text lines properly resulting in the wrong message
    issued when the maximum number of text lines is exceeded.
    

Problem conclusion

  • CSQVDTA has been updated to count the number of text lines
    correctly and to issue message DISPLAY ACTIVE TERMINATED WITH
    MAX LINES when the number of text lines exceed the maximum
    allowed for messages to the operator console.
