To identify and resolve transaction-related problems, you can use the standard WAS RAS facilities. If you encounter a problem that you think might be related to transactions, complete the following steps...
- Check for transaction messages in the administrative console. The Transaction service produces diagnostic messages prefixed by WTRN.
- Check for Transaction messages in the activity log.
- Check for more messages in the appserver's SystemOut.log.
- Check for messages related to the appserver's transaction log directory when the problem occurred.
If you changed the transaction log directory and a problem caused the appserver to fail (with in-flight transactions) before the server was cycled properly, the server will next start with the new log directory and be unable to automatically resolve in-flight transactions that were recorded in the old log directory. To resolve this, you can copy the transaction logs to the new directory then stop and restart the application server.
