The following tutorial will briefly discuss the different commands we can use to monitor the GoldenGate environment and get statistics and reports on various extract and replicat operations which are in progress.

More details can be obtained from Chapter 19 of the Oracle GoldenGate Windows and Unix Administration guide – Monitoring GoldenGate processing.

Viewing the GoldenGate error log as well as history of commands executed and other events

We can use the editor depending on operating system – vi on Unix for example to view the ggserr.log file which is located at the top level GoldenGate software installation directory.

We can also use the GGSCI command VIEW GGSEVT as well.

View the process report

Every Manager, Extract and Replicat process will generate a report file at the end of each run and this
report can be viewed to diagnose any problems or errors as well as view the parameters used, the environment variables is use, memory consumption etc

For example:

GGSCI (devu007) 2> view report ext1 GGSCI (devu007) 2> view report rep1 GGSCI (devu007) 2> view report mgr Information on Child processes started by the Manager GGSCI (devu007) 8> send manager childstatus Sending CHILDSTATUS request to MANAGER ...
