Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

Distributing log files

OpenEdge creates the following log files:

Event log, which contains a history of significant database events, such as OpenEdge startup and shutdown and system errors. This file always has a .lg extension. Place the event log file in the same directory as the database file.
Transaction log, if you are using the two-phase commit feature. The log records two-phase commit transactions, and uses a .tl extension. The transaction log file belongs on the same disk as the database.
OpenEdge AppServer log, if you are using the OpenEdge AppServer option. The log records OpenEdge AppServer broker and server startup and shutdown information, and it contains other system messages that are not directed elsewhere with the OUTPUT TO KEEP-MESSAGES statement. The default location of the AppServer log is the directory where the application broker starts. For information about moving the AppServer log file, see OpenEdge Application Server: Developing AppServer Applications .
