Error description

  • Tibco EMS connectivity might be lost and not reconnected when
    retry logic fails.  Backup might not reconnect and additional
    fault tolerance groups are not considered in retry logic.
    

Local fix

  • The Tibco EMS Server object admin-state can be disabled, then
    enabled and allow the connection to take place.
    

Problem summary

  • For DataPower user who uses TIBCO EMS Service and set more than
    one Fault-Tolerance Pairs, when TIBCO EMS connectivity is lost,
    the reconnect logic doesn't work well, and sometimes it doesn't
    try all provided backup FT-Pairs. Some TIBCO EMS servers in the
    backup list are skipped even if they are up and available.
    Finally the reconnection fails.
    

Problem conclusion

Temporary fix

  • Restart TIBCO EMS Service (disable and enable it).
