Requirement to display the contents of the USS directories with USS commands to verify the USS directories structure is correct.

The following USS commands will give you the mount information for the USS directories, the permissions for the directories, as well as all the files contained in the directories.

MOUNT FILESYSTEM('hlq.CDBAZFS')  MOUNTPOINT('/xxx/xxx/dbmgmt') TYPE(ZFS) MODE(RDWR)
 
Then run the following USS commands to get the information about the USS directories.

ls -la /xxx/xxx | grep dbmgmt
ls -R /xxx/xxx/dbmgmt

The USS commands can be executed through OMVS, or using BPXBATCH program.
