When using AXA 17.3, you may encounter issues with disk space, certain logs can grow very large.

In particular, the $CA_EMM_HOME/logs/mdoaggregatorscript.out file and $CA_EMM_HOME/java/axa-transformer/lib/nohup.out file can take up many GB, even hundreds of GB of space.
AXA 17.3
The logs are created from redirected stdout from the processes. There is no log4j configuration for the logs so they can grow uncontrolled.

The scripts that start these processes can be reconfigured to send the stdout to /dev/null. The additions to the default configuration are highlighted in bold:

  • $CA_EMM_HOME/java/mdo-aggregator/bin/


nohup ./Aggregator >> $CA_EMM_HOME/logs/mdoaggregatorscript.out > /dev/null 2>&1 &


  • $CA_EMM_HOME/java/axa-transformer/bin/


nohup "$javaExe" -XX:+HeapDumpOnOutOfMemoryError -Xms1024m -Xmx2048m -XX:NewRatio=2 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -Djava.awt.headless=true  -Dservice=CA_AXA_TRANSFORMER -Djava.library.path=../lib -jar $jar_name -classpath "$CLASSPATH"  > /dev/null 2>&1 &

These configuration changes will be added to the product in a future release
