# Installing your Talend JobServer

Information noteImportant: You may need to change the java.library path in order to load the correct native library for your system. In this case, adapt the variable MY\_JSYSMON\_LIB\_DIR in the script start\_rs.sh.

Talend JobServer is an application that allows a system installed on the same network as the Web application to declare itself as an execution server. These systems must obviously have a working JVM. For more information about the prerequisites of Talend JobServer, see [Compatible Operating Systems](https://help.qlik.com/talend/en-US/installation-guide-linux/8.0/compatible-operating-systems "This page details the recommended and supported Operating Systems for Talend products.").

## Information about Talend JobServer resources and load balancing

Once you have declared these execution servers in the Servers page of the Talend Administration Center Web application, their resources (CPU, RAM, etc.) are displayed. For more information on how to do this, see [Configuring execution servers](https://help.qlik.com/talend/en-US/administration-center-user-guide/8.0/prerequisites-to-configuring-execution-servers).

For users working in cluster mode, note that the ranking of servers to be used for load balancing is based on indicators, whose bounds (such as free disk space limits) and weight are defined in the monitoring\_client.properties file which is located in <ApplicationPath>/WEB-INF/lib/org.talend.monitoring.client-A.B.C.jar. These values can be edited according to your needs. For more information, see [Configuring the indicators which determine which server to be used for load balancing](https://help.qlik.com/talend/en-US/installation-guide-linux/8.0/config-server-load-balancing "You can edit and overwrite the default configuration used to determine which server to be used for load balancing in cluster mode.").
