Steps to Increase the Memory Pool for Smart Reporting

Windows
1. Open the Tomcat configuration window:

• Bundled Tomcat: use below command on command prompt:<SmartReportingInstallDir>\appserver\bin>tomcat8w.exe//ES//BMCSmartReporting
• External Tomcat: go to <Tomcat_install>\bin\ and execute Tomcat8w.exe file

Note: file name will depend on the Tomcat version i.e. Tomcat7w.exe, Tomcat8w.exe, Tomcat9w.exe etc.

2. Update the values for Initial and Maximum memory pool as per the requirement.

Refer to the attached document for additional information.

Linux/Unix
1. Shut down Smart Reporting service using the shutdown.sh command
2. Create a backup of file catalina.sh located at following path:

• Bundled Tomcat: <SmartReportingInstallDir>\ appserver\bin\catalina.sh
• External Tomcat: <Tomcat_install>\bin\catalina.sh

3. Edit the original catalina.sh file and find the below section in the file and update the values Xms and Xmx parameters
# Memory limits. 
# Use these options to set the Java memory limits. 
# -Xms64m sets the initial Java heap size to 64 MB
# -Xmx256m sets the maximum Java heap size to 256 MB 
#JAVA_OPTS="$JAVA_OPTS -Xms64m -Xmx256m" 

4. Uncomment the last line and change the Xmx option to the desired max memory setting.
5. Start Smart Reporting service using the startup.sh command
