ALTER MEDIADB Command (Super Group Only)
SECURE "code"
defines the new security level for the file catalog. Specify code as a character
string representing operating system security levels for read, write, execute, and
purge access. Enclose the string in quotation marks. For information on security
levels, see the Guardian User’s Guide.
Consideration
Take care when changing the values of the security level or owner of a file catalog.
Assuming the values were correct when the file catalog was created, use ALTER
FILECAT only if the purpose or users of the catalog have changed.
Examples
1. This example changes the security level of the file catalog FILE_CATALOG_SKY
on \SKY. The catalog’s present security is GG-O, so only local users in the owner’s
group on \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 FILECAT PAYROLL_CATALOG, SECURE "NG-G"
Security of NG-G is often a good choice for a file catalog. However, changing to
this level with ALTER FILECAT results in a warning message from NonStop
SQL/MP. You do not have to be concerned with this expected message.
2. To change the owner of the file catalog:
MC> ALTER FILECAT FILE_CATALOG_SKY, OWNER 5,149
ALTER MEDIADB Command
(Super Group Only)
To modify volume catalog tables to contain the information necessary to support
TAPEFORMAT, invoke the ALTER MEDIADB command. It is typically invoked once
during software installation but can be invoked as often as necessary; for example, if a
user accidentally restores an old version of a Volume Catalog.
The command causes the MediaCat component on the local node to upgrade all local
Volume tables in the current MediaCat Map table. Remote Volumes are ignored.
The command returns a list of successfully modified catalogs, skipped (remote)
catalogs, and unsuccessfully modified catalogs.
