APAR status

  • Closed as program error.

Error description

  • Following a restart, performance becomes increasingly worse and
    system reprots many rollback attempts related to calculations.
    

Local fix

  • Changed the default value of the calculation engine to make it
    use one thread instead of multiple so the locking will not
    happen anymore.

Problem conclusion

  • The main issue here is that a Calc Job  is accessing a DB
    connection even after the connection is released back to the
    connection pool. It happens when the system is crafting the
    error message to write to the aurora log. The fix is to craft
    the error message BEFORE the persistenceManager releases the DB
    connection back to the pool.
    
    NOTE:  This is fixed in 8.2.0.1 and also in 8.2.0.0.3
    
    Customers should download OpenPages with Watson 8.2 Fix Pack 1
    (8.2.0.1). See the following document for details on obtaining
    OpenPages 8.2.0.1:
