Property PCD.Home
This variable value defines the location of the PCD configuration file. In a clustered environment, this should be a central location (that is, shared between all server nodes of a cluster) in order to provide a common configuration for the whole cluster.
The value of PCD.Home is defined by default by the J2EE Engine. A shared global directory, that is used by all the applications of the J2EE Engine, is used. The global directory for the PCD resides at /usr/sap/<Instance>/sys/global/pcd.
This directory also contains the PCDStartup.Properties configuration file.
The value of PCD.Home can be overridden by a system property.
