Environment

Release: All supported Jaspersoft releases

For Windows:

• Stop the Jaspersoft services 
• Navigate to Jaspersoft Installed folder cd <js-install>/apache-tomcat/bin/ and edit setenv.bat
• Look out for JAVA_OPTS and update the default parameters below:
  • SET "JAVA_OPTS=-Xms1024m -Xmx2048m -XX:PermSize=32m

For Non Windows:

• Stop the Jaspersoft services 
• Navigate to Jaspersoft Installed folder  <js-install>/apache-tomcat/bin/ and edit setclasspath.sh
• Look out for JAVA_OPTS and update the default parameters below:
