All nodes that host applications that are configured in WPARs must run the same version of the operating system.
Mounts must meet one of the following two conditions:
Use a loop-back file system. All mounts that the application uses must be part of the WPAR configuration and must be configured in the service group. For example, you can create a WPAR, z-ora, and define the file system containing the application's data to have the mount point as /oradata. When you create the WPAR, you can define a path in the global environment, for example /export/home/oradata, which the mount directory in the WPAR maps to. The MountPoint attribute of the Mount resource for the application is set to /export/home/oradata.
Use a direct mount file system. All file system mount points that the application uses that run in a WPAR must be set relative to the WPAR's root. For example, if the Oracle application uses /oradata, and you create the WPAR with the WPAR path as /z_ora, then the mount must be /z_ora/root/oradata. The MountPoint attribute of the Mount resource must be set to this path.
