Changing the PSM Properties File

 

The /usr/local/ems9001/conf/common.properties file is read on startup and contains parameters that control certain aspects of the PSM server behavior. This file is read-only and should not be modified by the user.

To make changes to the parameters specified in this file, modify the /var/local/ems9001/conf/override-common.properties file instead. As the name suggests, the override-common.properties file overrides the settings in the common.properties file. On startup, the PSM server reads the common.properties first, and then the override-common.properties file.

The override-common.properties file typically contains only parameters that have different values from their equivalents in the common.properties file. If a parameter appears in both files, the parameter value in the override-common.properties file takes effect.

Note

The /var/local/ems9001/conf/override-common.properties file survives PSM server software upgrades. You do not need to manually reinstate the property changes after the upgrade.

The common.properties file and, by correlation, the override-common.properties file may contain both user-settable and system-level parameters that affect the behavior of the PSM server. Only those attributes explicitly described in this guide should be changed. Changing any other attributes may have unintended consequences, and must only be performed under the guidance of Juniper Networks Support.

All changes to the /var/local/ems9001/conf/override-common.properties file should be tracked with Git. See Using Git to Track override-common.properties for information on how to do this.
