Consideration
Take care when changing the values of the security level or owner of a volume catalog.
Assuming the values were correct when the volume catalog was created, use ALTER
VOLCAT only if the purpose or users of the catalog have changed.
Examples

This example changes the security level of the volume catalog
MASTER_TAPE_CATALOG on \SKY. The catalog’s present security is GG-O, so
only local users in the owner’s group of \SKY have read and write access to it, and
only the local owner can manually delete entries from it.
After the command executes, the catalog’s new security of NG-G lets all users
from any node retrieve information from the catalog, but they cannot add new
entries, nor can super-group users on those nodes manually delete entries.
MC> ALTER VOLCAT MASTER_TAPE_CATALOG, SECURE "NG-G"
A security of NG-G is often a good choice for a volume catalog. However, changing
to this level with ALTER VOLCAT results in a warning message from NonStop
SQL/MP. You do not have to be concerned with this expected message.

To change the owner of the volume catalog:
MC> ALTER VOLCAT MASTER_TAPE_CATALOG, OWNER 5,149
