Checking the execution results of the dbmigration tool

The activity of the dbmigration tool can be logged using the log4j feature.

If needed, you can change the log4j configuration information in the file <$INSTALLDIR>/tools/dbmigration/ For more information on the log4j logging levels, see the Apache documentation at

An example of the file is shown below:

log4j.appender.CONSOLE.layout.ConversionPattern=%p [%c] - %m%n

log4j.appender.FILE.layout.ConversionPattern=%d %p [%c] - %m%n

By default, the log information is stored in the file <$INSTALLDIR>/tools/dbmigration/dbmigration.log.

When you migrate MDM instances using the dbmigration tool, you can check the log information in the file dbmigration.log to troubleshoot migration issues.

The following is an example of an error message in the file dbmigration.log:
2015-12-16 18:25:36,486 ERROR [] - Unable to commit on 'Product' (total 2 records, some of them rollbacked)

Additionally, you can check the file <$INSTALLDIR>/logs/mdm.log on the source MDM server and target MDM server respectively to learn more information about the execution results of the dbmigration tool.
