java_options

Background

This option allows you to set command-line options to the JVM. For example, to increase stack space, etc. This will be used when launching most of the Java based components in Funnelback. These include the web crawler, the file system gatherer and the text filtering framework.

Setting the key

Set this configuration key in the search package or data source configuration.

Use the configuration key editor to add or edit the java_options key, and set the value. This can be set to any valid String value.

Default value

java_options=

Examples

Specify a JVM heap parameter:

java_options=-XX:+AggressiveHeap

Specify a system property:

java_options=-Djava.net.preferIPv6Address=true

Notes

Invalid options will cause the Java interpreter to fail, or perform badly.
