Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of zSecure exploiting                  *
    *                 - zSecure Alert (C2POLICE),                  *
    *                 - zSecure Access Monitor (C2PACMON),         *
    *                 - the near real-time SMF feed for SIEM using *
    *                   the zSecure SMF collector (CKQEXSMF).      *
    ****************************************************************
    * PROBLEM DESCRIPTION: The zSecure data analysis tasks might   *
    *                      enter an infinite loop if record data   *
    *                      is incomplete.                          *
    ****************************************************************
    * RECOMMENDATION: Apply the PTF provided.                      *
    ****************************************************************
    When the zSecure data analysis process tries to obtain records
    from the in-storage buffers it might encounter a partial record
    that is still being added to the buffer. Using data from the
    partial record might cause an infinite loop loosing the
    functionality and consuming a lot of CPU time.
    

Problem conclusion

  • zSecure has been modified so that the zSecure data analysis
    process does not use partial record data from the in-storage
    buffers.
