Increase Java heap space in OBIEE 12C


By on April 09, 2017



1 Use the WebLogic Server Administration Console to shut down the servers gracefully.

2 Open the setDomainEnv.sh file (or setDomainEnv.bat on Windows systems) for editing. You can find this file in the DOMAIN_HOME/bin directory.

3 Locate the IF statement for USER_MEM_ARGS and place the insertion point before that statement.

4 Set the -Xmx argument for USER_MEM_ARGS. The following list shows examples of how to set USER_MEM_ARGS for various operating systems:


Find this code and edit

# Set the -Xmx argument for USER_MEM_ARGS. Increasing the JVM java heap: Date 20160620: Lerato Motaung

if [ "${SERVER_NAME}" = "" ] ; then

SERVER_NAME="AdminServer"

USER_MEM_ARGS="-Xms4096m -Xmx4096m -XX:CompileThreshold=8000 -XX:MaxPermSize=4096m"

export SERVER_NAME  also find this code and edit



# IF USER_MEM_ARGS the environment variable is set, use it to override ALL MEM_ARGS values

# Set the -Xmx argument for USER_MEM_ARGS. Increasing the JVM java heap: Date 20160620: Lerato Motaung

USER_MEM_ARGS="-Xms4096m -Xmx4096m -XX:CompileThreshold=8000 -XX:MaxPermSize=4096m"

if [ "${USER_MEM_ARGS}" != "" ] ; then

MEM_ARGS="${USER_MEM_ARGS}"

export MEM_ARGS



1 After setting the parameter, save and close the file, then restart the Administration Server and Managed Servers for the changes to take effect.

2 In a scaled-out system, repeat these steps for each domain home. Note that if you scale out the system at a future point, then you must perform these steps for the new node (the settings are not copied to the new node's domain home).
