Subject: RE: RE : RMAN RepositoryYou can have a very large site and still do just fine without an RMAN
repository. RE the "non-database solution," Oracle has already done that,
it's called the controlfile. I tend to agree with Robert F. who "wrote the
book" on RMAN where, in another post he wrote, "I actually find the repository
of little use. If I have an enterprise with many databases then I will use it
for reporting but that's about it. It just seems to complicate the overall administrative costs and thus, the burden/benefit ratio is not all that good."Use of the RMAN repository WAS "strongly recommended" by Oracle in the past
but things have changed and that "truism" no longer holds. You can see this
transition if you compare the recommended practices in the current Oracle
documentation against recommended practices in the old docs (8.0 or even the
7.X EBU stuff). I'm not the least bit surprised that Oracle is working on
eliminating this silly dependency on another database. The only dependencies
should be, "Is the Oracle software installed on the machine you want to
recover to and does it have access to the backup media?"
IMHO, :-)

Steve - My theory is that if your site is sufficiently large to be worth
considering an RMAN catalog configuration, then you can easily find a
location for it. For us, that was easily solved. If Oracle had created a
non-database solution, then that would have become a development project all
its own. And people would have pointed out the contradiction of a database
company creating a non-database solution. And we would have whined about
having to learn a non-SQL interface. But where Larry is concerned I would
never count out the profit motive.

To: Multiple recipients of list ORACLE-LYeah but do you have to pay for another Veritas NetBackup license and server
to backup the catalog? If just have one database server and one database
license why should I have to buy another license and install another 1-2GB
of Oracle software on another server? The only answer I can think of is so
Larry can spend more money on yachts, planes, and cars.Contrary to Oracle Corporate aspirations, not all data in the universe
really needs to be stored in Oracle databases, especially backup information
about Oracle databases I want to backup. If I need a database to backup a
database then do I need another database to backup the database that backed
up the original database? ;-) Seems the simple solution to this silliness is
just to remove the requirement of having a database to backup a database.

It isn't any more silly than making a separate backup of the Veritas
Netbackup catalog.It's just a different level of abstraction.

Subject: RE: RE : RMAN Repository
If you aren't using a repository all you have to do is make sure control
file backups are part of the routine. There are 2 ways to backup the
backup metadata: 1) the RMAN repository database; 2) backup controlfiles.
Functionally and operationally they're pretty much the same. The only
things you can't do with controlfile RMAN/database metadata is: 1) use
previous "incarnations" of the database for recovery; 2) use database
stored scripts. No big deal as far as I'm concerned.
When RMAN first came out a separate repository database was a requirement.
Subsequent releases added some functionality for using controlfiles. The
vulnerability of losing the repository or losing the backup controlfile is
about equivalent. The overhead of the repository database is more. With
the initial releases of RMAN (EBU) Oracle was rightly criticized for the
fact that you had to backup the database that holds information about the
database you want to backup. Getting rid of this silliness seems
reasonable to me.Steve Orr-man for RMAN,

Importance: HighAnd how does one go about restoring a database when all control files
are lost, and the only recovery data is stored in the control file?
This doesn't sound very reasonable.

Joe,
That's what I have heard (from 2 Oracle University
Professors/Lecturers/Demonstrators). But no one would tell me when it may
happen. We do not use RMAN (yet) so I did not pursue it further.

Obilgatory oracle statement/question: rumor has it by some instructors
that RMAN repository is going away and only control file recoveries
will be possible, truth or fiction?

Title: RE: RE : RMAN Repository
I
agree Steve, and thanks for the info.
Do you have any procedures to cover backup logic
holes if you
have
to rebuild the controlfile for some reason (Ie.. maximum files reached
etc)
Do you
accept losing the backup history and cross fingers or ... have
procedure
to
account for that?
