1.11 Changing the JVM Configuration Settings

Depending on the amount of memory allocated to your appliance (see Memory Requirements in the Novell Filr 1.2 Installation and Configuration Guide), you might need to adjust your Java heap settings as described in this section.

  1. Follow the steps in Section 1.1, Changing Configuration Options for the Filr Appliance.

    You can modify the following configuration options:

    JVM Min Heap Size: The default JVM minimum heap size is 5 GB. You can increase or decrease this value as needed.

    JVM Max Heap Size: The default JVM minimum heap size is 5 GB. You can increase or decrease this value as needed.

    The values for the JVM heap size must end with g or m, and cannot contain fractional values. For example, if you want your JVM minimum heap size to be 1.5 GB, you must specify 1536m.

    It is recommended that the JVM Min Heap Size and JVM Max Heap Size values be the same. If the values differ, Java begins with the minimum, and if it requires more resources, proceeds up to the maximum. This process can be resource intensive and degrade system performance.

    Allow generation of a system dump on a user signal: Select this option to configure Filr to generate a system dump in addition to a heap dump and java core dump at the time a dump is triggered on a user signal.

    This can be useful when troubleshooting issues with your Filr system. However, a system dump takes more time and the files consume more disk space than a heap dump or java core dump.

    Java Home: Displays the path to the JavaHome variable. This cannot be changed.

  2. Click OK, then click Reconfigure Filr Server for your changes to take effect.

    This stops and restarts your Filr server. Because this results in server downtime, you should restart the server at off-peak hours.
