Troubleshooting Lifecycle Query Engine

Edit online

If errors or exceptions occur while you are using Lifecycle Query Engine (LQE), use the log files and application logging to research and resolve the issues.

Note: For ELM version 7.0.2 SR1 iFix015 and later, the logging property file name and configuration parameters are changed because of the move to Log4j2. For more information on the updates, see IBM Support portal.

The following log files are generated by LQE:

LQE log: JTS_ROOT/server/logs/lqe.log
LQE properties: JTS_ROOT/server/conf/lqe/lqe.properties
Jazz® Team Server log: JTS_ROOT/server/logs/jts.log
WebSphere® Liberty log: JTS_ROOT/Server/logs/lqe.log
WebSphere Application Server log: WebSphere_Install_Dir\AppServer\profiles\server_name\logs\lqe.log

You can download the LQE logs from the Advanced Properties administration page at https:<Host_name>:<port>/lqe/web/admin/advanced. The settings in the Install_dir/server/conf/lqe/log4j.properties file determine what logs you have and where they are.
