Yep... and we've seen this problem before.  The Oracle file systems may need
to be "owned" by the Oracle dba-id;  then, the file/directory permissions
can be set with user or group permissions that allow the same Ora dba-id to
read-write-execute.  When this is the case, "root" cannot do backup/restore
since it lacks file system and file access permissions... so, AutoSys or
Cron are used by the Ora dba's to schedule their backups.  And, always, the
Oracle dba must handle restores.

In case "root" owns the Ora file systems, and has permissions to run the
backups, I've used a separate daemon, with pre-schedulecmd to (a) suid to
the Ora dba-id, then (b) run the Ora admin script for shutdown of the db's;
then the backup runs, and a post-schedule cmd runs the Ora admin script to
start up the db's.  If Ora dba-id has file permissions, they can always do
the restores at their convenience.

Hello Geoff,
        Since you're memo did not provide any history, I'm making some
assumption here forgive for starting at the top:
        Though we're running UDB EEE, this should still apply.  If the
Oracle person can backup to *SM then he/she should be able to restore
modifying their operating system privileges.
        They should be able to backup their database to the filesystem and
restore from that backup (the is totally independent of *SM).   If not it's
an access privilege issue (ex. user doesn't have the right user group
privileges; user trying to write out to a filesystem they don't have access
to) and or setup issue
(ex. flags are not set...sorry don't know Oracle well enough to provide
examples, or USERID does not have backup/restore privileges within Oracle
the Senior Oracle DBA must set this up).
        Do you and/or the UNIX Admin know for certain whether or not this
"pseudo" individual" has backup their data to the local filesystem? If they
can perform a successful backup and restore to/from the filesystem but they
have not backup to *SM I would suggest checking the  *SM API configuration
you setup.
