where the data class and data set name depend upon site standards. Allocation of this file to a mount point can be done in the PARMLIB BPXPRMxx member or through OEIS or through OMVS. The OMVS command would be:
mount -t HFS -f 'OMVS.PROD.ADV' /u/prod/adv
where, again, the /u/prod/adv mount point depends upon the site -- it is a defined directory. If there are any files or directories in /u/prod/adv before the mount command is done, they will not be accessible as long as the mount is active; they become available again once the unmount is issued.
