"An error occurred analyzing the ARM log file" might display when using the Aggregation Tuning wizard


When using the Analyze option in the Aggregation Tuning wizard, you might see the following error if there are blank lines in the specified ARM log.

An error occurred analyzing the ARM log file. Verify that a valid ARM log file has been specified.

Invalid ARM file, cannot continue: Unrecognized format (could be an encoding problem).

To resolve this issue, open the ARM log in a text editor, remove all of the blank lines, and then save the file.

To prevent blank lines from being inserted into ARM log files, you can add the following lines to the logconfig.xml. The default location for the logconfig.xml file is <sas-config-dir>\Lev1\SASApp\OLAPServer\logconfig.xml.

In the Server Administration Message Logger section, add  additivity=”false” to the  logger name attribute, as shown below:

<!-- Server Administration Message Logger --> <logger name="Perf.ARM.IOM.Server.ServerAdministration" additivity="false"> <level value="Debug"/> <appender-ref ref="Events"/> </logger>

This entry prevents Perf.ARM.IOM.Server.ServerAdministration messages from being sent to the Perf.ARM logger.

After modifying the logconfig.xml file, restart the SAS OLAP server.
