Memory settings for RPA processes

The page describes how to configure memory settings for RPA processes (Hub, Node, Platform Monitor).

Configure Hub

To configure the Hub process memory settings:

  1. Specify the -Xms and -Xmx parameters in the following file:

    $RPA-installation-directory/rpa-grid/start-hub.bat

  2. Add the following parameters after the Java call:

    ...\java\bin\java -Xmx256m -Xms256m

  3. Restart the Hub.

Configure Node

To configure the Node processes memory settings:

  1. Specify the -Xms and -Xmx parameters in the following files:

    $RPA-installation-directory/rpa-grid/start-nodeX.bat


// where X is the Node number (starts from 0)

  2. Add the following parameters after the Java call:

    ...\java\bin\java -Xmx256m -Xms256m

  3. Restart the Node.

Configure Platform Monitor

To configure the Platform Monitor process memory settings:

  1. Specify the -Xms and -Xmx parameters in the following file:

    $RPA-installation-directory/wfagent/bin/wfagent.cmd

  2. Add the following parameters to the java_opts variable:

    set java_opts=-Xmx256m -Djava.awt.headless=false -Dtray.type=RPA -Dfile.encoding=UTF-8

  3. Restart the Platform Monitor.

By default, it is recommended to specify -Xmx256m -Xms256m. But it should be configured according to your use case. For example, if your use case invokes a lot of applications on RPA Node, you should increase these parameters.
