Working with Messaging Gateway QUEUE_NAME FAILURES LAST_ERROR_MSG ----------------------------------------- MGWUSER.SRCQ 0 You can use the MGW_SCHEDULES view to check which schedules are configured and which are enabled. Checking for Configured and Enabled Schedules: Example SQL> select schedule_id, schedule_disabled from MGW_SCHEDULES; SCHEDULE_ID SCH ------------------ SCH_AQ2MQ N (N = not disabled; that is, enabled) Monitoring the Messaging Gateway Log File Messaging Gateway agent status, history, and errors are recorded in the Messaging Gateway log file. By default, it is located in the $ORACLE_HOME/mgw/log directory. You should monitor the log file because it is where both updates and errors are reported. A different log file is created each time the Messaging Gateway agent is started. Sample Log File The following sample log file shows the Messaging Gateway agent starting. Tracing information and errors are logged to this file.

When configuration information is read at startup time or when dynamic configuration occurs, the information is written to the log. In the sample log file you can see that a link, a registered foreign queue, a subscriber, and a schedule have been created. The log shows that the subscriber has been activated. Any errors also appear in the log. The last line indicates that the Messaging Gateway agent is up and running. Messaging Gateway converts the native message format of the source messaging system to the native message format of the destination messaging system during propagation. Messaging Gateway uses canonical types and an AQ-centric model for the conversion. Messaging Gateway 18-27
