Information Server EngMonApp fails with java.lang.OutOfMemoryError

-

Resolving The Problem

To resolve the issue, you need to increase the maximum heap size for EngMonApp by following these steps:
1. Log into server as dsadm or root.

2. cd InformationServerRoot/Server/DSODB/bin/utils_private/

3. Back up the DSEngMonApp.sh file
cp -p DSEngMonApp.sh DSEngMonApp.sh.bak

4. Edit DSEngMonApp.sh file to increase -Xmx384m, for example to -Xmx896m (896 megabytes).

#$APW_NOHUP_CMD "$JAVA" -DPSMARKER=$PSMARKER -Xmx384m -classpath "$CLASSPATH" com.ibm.datastage.runtime.engmonapp.EngMonApp 1>&2 &
$APW_NOHUP_CMD "$JAVA" -DPSMARKER=$PSMARKER -Xmx896m -classpath "$CLASSPATH" com.ibm.datastage.runtime.engmonapp.EngMonApp 1>&2 &

You may need to try different -Xmx values until you find an adequate heap size.

5. Restart EngMonApp by starting the DataStage AppWatcher service:
InformationServerRoot/Server/DSODB/bin/DSAppWatcher.sh -start
on unix as the DataStage administration user (e.g. dsadm).

BLAFS is a bloat-aware filesystem for container debloating. The design principles of BLAFS are effective, efficient, and easy to use. It detects the files used by the container, and then debloats the container by removing the unused files. The debloated containers are still functional and can run the same workload as the original containers, but with a much smaller size and faster deployment. https://github.com/negativa-ai/BLAFS?tab=readme-ov-file
