Java: Out of Memory Error - System Unavailable

This requires being connected to your server.

Problem:

Trying to access the iDashboards application throws following Java error:

Unexpected error: java.lang.OutOfMemoryError: Java heap space java.lang.OutOfMemoryError: Java heap space

Information:

This is an error that is thrown when the Java Virtual Machine has run out of resources that are necessary to continue the operation. Increasing the memory allocated to the application server will resolve the issue.

Resolution:

To increase the Memory Allocated to Tomcat:

1. Open Apache Tomcat Configuration in the system tray
2. Right click on Service
3. Select Configure  
   • You may need to add a desktop shortcut, know that your path might differ from the one listed. 
     • Open Command Prompt as Administrator then type in the following:
       • cd C:\Program Files\iDashboards_SRV\ivizgroup
     • Hit Enter then type in the following:
       • idashboardsw //ES//iDashboardsSRV
     • Your iDashboards Server Properties will now open
     •  
4. Open Java
5. Adjust the Initial Memory Pool Size to 512MB
6. Adjust the Maximum Memory Pool Size to 1024MB
7. Click OK
8. Restart the Tomcat/iDashboards Service
9. Monitor the system

You will need to consult your documentation for other applications servers. Depending on how much memory your server has and what else is running on it, you might be able to give more memory to Tomcat. For example, if it has 4GB with nothing else significant running on it (like a database server) you can use 512 initial and 1024 max.

If the above is unable to resolve the issue, then please contact iDashboards Support for further assistance.
