APAR status

  • Closed as program error.

Error description

  • Customer reported that any kind of DB slowdown would result in
    the IBM Traveler servers maxing out the DB connections, which
    would overload the DB server.
    
    We are reviewing the algorithm for spawning new connections to
    see if can make it more aware of the current DB server state.
    

Local fix

  • NA
    

Problem summary

  • Some customers have complained that during a db outage or
    performance slow down that the IBM Traveler server would
    immediately open 200-300 database transactions per Traveler
    server which would make matters worse for the database server.
    

Problem conclusion

  • The IBM Traveler server has been updated to limit the amount and
    speed which it will generate database connections.  This should
    greatly reduce impact to the database server especially during
    times of outage or performance slow downs.
    

Temporary fix
