APAR status

  • Closed as program error.

Error description

  • tpc agent registration errors resulting from a guid mismatch
    cause thousands of log entries in the tpc data server
    server_0000xx.log files, and also lead to db2 deadlocks because
    of the continuous registration/connection attempts and errors.
    this eventually causes the tpc server to be unresponsive, and
    can also prevent the user from logging in to the gui.
    data server and/or data agent code must be changed to prevent
    this behavior. log the message once, and then do not allow any
    further messages or database connection attempts from this
    agent until the problem has been corrected.
    

Local fix

  • implement tpc data server option 'dupcompinfo=override' or
    'dupcompinfo=decommission' in <tpc>/data/config/server.config
    &#65517;controller&#65529; section, then restart the tpc data server service
    or reboot the server.
