The effect of application server shutdown on active transactions and later recovery
When an application server shuts down, any active transactions are rolled back. If all transactions are successfully completed in this way, message WTRN0105I is logged, and on the next server restart no recovery activity is needed. If message WTRN0105I is not logged for an application server shutdown, this does not indicate that there has been a failure, only that recovery activity is required when the server restarts.
A clean shutdown of all application servers should be achieved before the product is uninstalled, to avoid data integrity problems.
