By default Tomcat (the bundled web server) is configured to use a maximum of 768 MB 2 GB of memory which is quite sufficient in majority of cases. In case this proves insufficient for you, you can increase it as follows:
- First determine the amount of memory you want to allocate. Typically, it should not exceed half of your installed RAM. For example, if you have 4 GB of RAM, then you can safely allocate 2 GB to Tomcat. Let's assume you want to set it to 1 4 GB i.e. 1024 4000 MB.
- Stop Celoxis
- Set the system environment variable CATALINA_OPTS to -Xms512M -Xmx1024M Xmx4000M (Note the dash in front of the X.)
On Microsoft Windows:
- Right click My Computer.
- Click Properties.
- Click the Advanced tab (or click Advanced system settings in Windows Vista).
- Click the Environment Variables button
- Under System variables, click New.
- Set variable name to CATALINA_OPTS and variable value to -Xms512M -Xmx1024MXmx4000M
- Click OK.
- Click OK on the Advanced tab to close the window.
...
- Open a terminal and login as the user that starts Celoxis.
- In the appropriate profile file (e.g. .bash_profile or .profile), type: export CATALINA_OPTS=-Xms512M -Xmx1024MXmx4000M
- Save the file.
- Logout and Login again.
- Start Celoxis.

Celoxis needs to start with a minimum of 512 MB and hence, we set the -Xms value to 512M. For 32-bit operating system, you need to set both the -Xms and -Xmx parameters as seen in the above screenshot. However, the Xmx parameter should only be set to 1GB i.e 1024M. |
