Managing software of the shared WPAR

The shared form (shared /usr) of a system WPAR has the /usr file and the /opt file systems mounted from the global system hosting the WPAR.

For shared system WPAR, all changes within the /usr file and the /opt file systems are immediately visible within the WPAR along with the installation files and information required to synchronize the non-shared (root) portion of the WPAR global system within the /usr file system. The syncwpar command will synchronize a shared WPAR with its global environment. You can use shared WPAR unless it is required that the /usr file systems be writable within the WPAR.
