WebSphere Enterprise Service Bus for z/OS, Version 6.2.0 Operating Systems: z/OS


Transaction log file

The transaction (tranlog) log file stores critical transactional data that is written to databases. It is an internal file that WebSphere® Application Server uses to manage in-flight transactions and attempt to recover them should the server crash.

DO NOT delete the transaction log file from a production environment. Deleting this file removes information on in-flight transactions from WebSphere ESB memory. Without the transaction log file, there is no functionality to recover transactional information. In addition, long-running processes remain in an inconsistent state and you cannot complete the process flow except by deleting running instances. Deleting running instances might cause you to lose operational or business-critical data, which makes the database inconsistent with the message destination. Other inconsistencies that may be caused by deleting the transaction log file includes the following:
Note: Deleting the transaction log from a development environment causes the same problems. Because you can recreate business processes, deleting the files from a test environment is not as damaging as deleting them from a production environment.
