Applications Manager may need an increase to Java memory if the below error is seen.
Error Message Details:
ErrorMsg: AwE-9999 Internal error (1/7/11 7:19 PM)
Details: null
java.lang.OutOfMemoryError: Java heap space
ErrorMsg: AwE-9999 Internal error (9/13/20 2:42 AM)
Details: GC overhead limit exceeded
Release: Version 9.x.x
The error above may occur due to Applications Manager's increased reliance on Java and there not being enough Java resources to handle the work. By default we allocate 1024 MB of Java memory, which may not be enough in some AM environments.
The error may occur whenever you run out of Java memory. This can occur at different times but we have seen this error occur most often when:
The java memory available to Applications Manager can be increased by adding a line in the sosite file, stopping the RmiServer/AgentService process, executing the sosite file to incorporate the change, and restarting the RmiServer/AgentService process.
If remote Agent, only the AgentService process needs to be restarted. Below are the instructions for Unix/Linux and Windows environments to increase the Java memory allocated to AM to 2048 MB.
UNIX / Linux
Edit the $AW_HOME/site/sosite file and add the appropriate AX_JAVA_OPTIONS line to the end of the file, then save the changes and exit.
For most UNIX operating systems add:
AX_JAVA_OPTIONS=2048m;export AX_JAVA_OPTIONS
Exception for SUN and TRU64 operating systems the syntax is slightly different:
AX_JAVA_OPTIONS=-Xmx2048m;export AX_JAVA_OPTIONS
Then execute the following commands for the change to take effect:
stopso all
cd $AW_HOME
. site/sosite
startso all
Verify that the change took effect:
ps –aef | grep java
You should see something similar to this, which indicates that the java process is utilizing 2048 MB of memory:
java -DAGENT=UNIXAGENT1 -Xmx2048m -DAW_HOME=/home/FOLDER1/unixagent1 -DOsType=UNIX com.appworx.server.data.AxRmiServer
Windows
Edit the %AW_HOME%\site\sosite.bat file and add the AX_JAVA_OPTIONS line to the end of the file, then save the changes and exit.
set AX_JAVA_OPTIONS=2048m
Then execute the following commands for the change to take effect:
stopso all
cd %AW_HOME%\site
sosite.bat
startso all
NOTE:
A dynamic Java memory range can also be set by modifying the AX_JAVA_OPTIONS variable similar to this:
AX_JAVA_OPTIONS="-Xms512m -Xmx2024m"
For Windows
AX_JAVA_OPTIONS=2024m -Xms512m
In the example above this entry would allow AM to allocate up to twice the normal amount of memory to be used by the RmiServer process as needed.
