discovery.properties Reference¶

The discovery.properties file contains startup and configuration information for the Discovery Search Engine.

NOTE: As of version 2.8.5, most of the discovery.properties settings have been migrated to discovery.settings. The Admin Tool now persistently stores settings applied in the interface to discovery.settings. Customers should not manually edit the settings file.

Basic Configuration Options¶

These options would be useful for all engine configurations. The discovery.properties file is read once at engine startup, so any changes made to this file will not be visible until the server has been restarted.

port¶

The port setting determines the port on which the Discovery Search Engine listens for requests. To choose another port, set the desired port number using this entry.

Default: 8090

Example:
port = 8091

jvm.memory¶

The jvm settings are passed to the JVM by the Discovery Search Engine startup script. The value for jvm.memory specifies the maximum memory in megabytes, the engine will use when running.

Default: 128

Example:

jvm.memory = 512

jvm.args¶

The jvm settings are passed to the JVM by the Discovery Search Engine startup script. The engine’s startup script will pass the value of jvm.args as a command -line parameter to configure the JVM. For example, customers who wish to take advantage of Java 1.6 compressed object references in a 64-bit JVM, may wan to specify the setting here.

Default: not set

Example:

jvm.args = -XX:+UseCompressedOops -XX:+DoEscapeAnalysis

total-partitions¶

This setting represents the total number of data partitions available to the current engine. For Master engines without data, total-partitions would be 0. For Query engines with data, total-partitions would be 1.

Default: 1

Example for Master:
total-partitions = 0
