Do you use RMAN?
Hi, I'm in the process of upgrading my database to 9i and I was trying to decide whether I wanted to change my backup strategy to use RMAN. Do most of you use it?

Do you use RMAN?
Bill ; I am just in the process of implementing RMAN at our shop. We decided to go with RMAN for the following reasons : * Reason1 RMAN manages what backups are required to perform the restore and where the backup are located (will get the files off tape). * Reason 2 The ability to perform HOT backups without the "ALTER TABLESPACE ..BEGIN/END" commands. This will reduce the amount of REDO that is generated during the backup. IE: You get HOT backups with out the adverse impact of the volume of redo. Since a datafile does not have to be placed in backup mode - there is no risk of the database going down during a hot backup and asking for media recovery. * Reason 3 The ability to only backup "used" Oracle blocks. This greatly reduces the amount of data that needs to be backed up. BACKUP SETS - Will only copy database blocks containing data. This saves on IO by not copying empty blocks. * Reason 4 The ability to detect database block corruption. Because RMAN uses Server Processes to perform its backup reads - it will raise the same error a SQL statement will raise upon detection of something amiss inside a database block. * Reason 5 The ability to perform incremental backups and restores. This greatly reduces the amount of data that needs to be backed up (block level backups). LEVEL 0 - Will copy all database blocks containing data (FULL). This saves on IO by not copying empty blocks. LEVEL 1 - Will copy database blocks that have changed since the most recent level0 bkup. This further reduces IO. LEVEL 2 - Will copy database blocks that have changed since the most recent level1 bkup. This further reduces IO. * Reason 6 A Enterprise Centralized Backup and Recovery solution. _ Patrick J.

I use RMAN with veritas Netbackup and it is sweet.

Re: Do you use RMAN?
I use it with 8i. We backup to disk. What I like: - Backups are faster. - Backup files are smaller. - "Duplicating" a test database from production is a breeze. What I don't like: - I find the report and list commands cumbersome. There have been numerous times that I needed to go into the repository and use SQL statements to find the information that I needed. - It is easy to corrupt your catalog when duplicating a database (try resyncing the duplicated database with your production catalog instead of registering). Make sure you have separate catalogs for production and test databases. It has been argued on this list that you should have a catalog for each database. - Can't duplicate a database using a specific cold backup without specifying "SET UNTIL...". This causes RMAN to look for the next redo log after the specified time or scn. Which means that after your cold backup, you need to do a log switch, then backup that redo log. RMAN isn't smart enough to know that it doesn't really need this post-cold-backup redo log. If somebody has a better way of doing this, I'd like to hear it. - I don't completely trust tools that "think" for me. DBAs who grow up on RMAN will have no idea what to do with database files that have been backed up the old fashioned way (alter tablespace x begin backup, cp file01.dbf file01_backup.dbf, alter tablespace x end backup). Understanding what RMAN is doing in the background is helpful. Overall, I give it an 8 out of 10.

RE: Do you use RMAN?
Bill - I'll take the contrarian stand, just so you see the "cons" as well as the "pros". I notice you say "my database" as in singular. If you truly are responsible for a single database, I would argue that RMAN may be more than you want to bite off. Most of us DBAs are paid as professional skeptics, so I'll ask you "what is wrong with your current backup methods?". I have worked with RMAN a little, and keep getting drawn away to production support, but I find it is difficult to work learn and hard to get up and going. On the other hand, everyone says that recovery is really nifty, assuming you have all the files RMAN needs. On the other hand, if you are planning to take the OCP exam for backup and recovery, then you should definitely start using RMAN, because I hear it is most of the exam.

RE: Do you use RMAN?
Pat & others, For your information something that I hope is helpful. To add a point we discovered the hard way - RMAN doesn't so much backup blocks containing data but rather it backs up blocks that have ever contained data. To quote from Metalink note 105208.1: "RMAN will not back up NEVER USED blocks, but will back up blocks that were used once, even if they are not in use now." This can be a problem if you're not using uniform extent sizes and you temporarily get (say) large indexes. In our case we worked around this at the time by rebuilding indexes to a new tablespace, resizing the original tablespace to a smaller value and then moving them back. Our longer term "fix" has been to move to LMTs with uniform extent sizes.

RE: RE: Do you use RMAN?
But if using a backup catalog, doesn't the catalog have to be the same exact version of the database being backed up? That is, RMAN 9i may be used to do the backups as long as it writes to an appropriately versioned catalog. Is my thinking correct?

Hi,
I'm in the process of upgrading my database to 9i and I was trying
to
decide whether I wanted to change my backup strategy to use RMAN. Do
most of
you use it? If you use it, what is your opinion of it? If you don't use
it,
why did you decide not to?

Re: Do you use RMAN? DB clone problem
I use this technique only as a failover routine, if the production machine
were to crash: Cloning I would use standards methods as it is much faster:
But once u restored the database you can rename it.
But the steps that I take are
1.Install executables on other machine as same owner and group id as
original database(this is very important)(RESTORE using Netbackup rather
than re-install)
2.Update bp.conf in oracle home and /usr/openv/netbackup/
3. set nb_ora_client=Original client
4.startup taget database nomount
5.connect rman catalog
6.Run scripts
Sam
p.s. scripts I use are
run {
allocate channel ch1 type 'sbt_tape';
restore controlfile;
alter database mount;
}
--select min(scn) from (select max(next_change#)scn from
v$archived_log
group by thread#); -- get the last scn in svrmgrl
run {
set until scn=100075926; allocate channel ch1 type
'sbt_tape';restore database;recover database;
}
--back in svrmgrl
alter database open resetlogs
