Configuring JVM values for Silk Central 17.0

0 Likes

In Silk Central 17.0 the java configuration for HEAP space is no longer specified in the registry. The settings are specified in separate, so-called process configuration files:

- sc_AppServer.processconfig
- sc_ChartServer.processconfig
- sc_FrontEndServer.processconfig


These configuration files are stored for each instance in the "conf" sub-folder of the instance's installation directory (e.g. C:\Program Files (x86)\Silk\Silk Central 17.0\instance_1_silk\Conf)

Inside such a file, you can specify the Java heap space for 32-bit and 64-bit mode:


- As an example, these are the default Java heap space settings in the default process configuration file for the application server

<JvmOptions> //64-bit mode
<JvmOption name="-Xmx" value="2048m" />
</JvmOptions>
<JvmOptions32bit> //32-bit mode
<JvmOption32bit name="-Xmx" value="512m" />
</JvmOptions32bit>

Note: To make changes active you have to restart the corresponding server process in the instance administration


The default Java heap space settings for the application, front-end and chart services are:

- Running in 32-bit mode:
application server: 768m
front-end server: 512m
chart server: 512m

- Running in 64-bit mode:
application server: 1280m
front-end server: 2048m
chart server: 1024m

Generally, we recommend to use the default values as specified in the process configuration files.
