RE: rman backup
Sorry to respond to such an old thread (man I'm way behind), but what if the
expected location of the archived logs isn't large enough? For example,
let's say we have a 10G archive directory, and we dump 5-10G of logs per day.
I have to go to a backup made a week ago. That's 35-70G worth of logs if I
need to roll forward. Does RMAN try and cram 'em all in at once, or will it
roll through them? That sure would be a nice feature. ;-)

When you have RMAN back up archived logs, IIRC, in a recovery RMAN first
restores those archived logs to the location that Oracle will expect them to
be, and I believe that is done as part of the RESTORE DATABASE command. In
my situation, I found no advantage from having RMAN store the archive logs,
so I have no experience there, just what I've read in the manual.
Only RMAN can perform the RESTORE DATABASE command, but once you
complete that command, you can complete the recovery using svrmgrl. From
everything I've seen, RMAN just issues the RECOVER DATABASE command to
svrmgrl or SQL*Plus.

My confusion is , does RMAN sees only those archived logs which are backup
using rman or it can use current archived log as well stored in original

We take daily rman backup each nite at 10pm . Which means in worst case we
risk one day of work. Now suppose something wrong goes before 10 pm .
Then
Can I recover my database till time using previous day rman backup and
currently available archived logs.
Or in nutshell is it possible to run { restore databse; recover database }
from rman and then apply remaing archived logs from a separated disk ( not

Re: rman backup
You can restore database and open it to the mount phase using RMAN.
Then you can get into sqlplus and type something like:
alter system set log_archive_dest_1=/directory/where/log/archives/reside
set autorecovery on
recover database auto until cancel

Besides you may refer to Backup Recovery by Rama Velpuri (8/8i). A bit old but nevertheless good. All said and done, create a clone database and keep crashing it in all ways you can think of, and try to recover it.

Ronald,
It looks like just the archivelog was not going into the correct
directory, right? But then you did *not* include a format clause for
the archivelog.
Looking at the docs, it looks like you should change the following:
backup database format
'D:\backup\oracle\Hotbackup\rman_d%d_t%t_U%U.bak' plus archivelog;
to
backup database format
'D:\backup\oracle\Hotbackup\rman_d%d_t%t_U%U.bak' plus archivelog format
'D:\backup\oracle\Hotbackup\arcs_d%d_t%t_U%U.bak'

RE: RMAN Backup piece being placed in wrong directory
Syntax error:
backup database format =
'D:\backup\oracle\Hotbackup\rman_d%d_t%t_U%U.bak' plus archivelog;
add the = after the format and it should run. RMAN is trying to help you
by ignoring this error and proceeding to backup the database to the default
location.

Ronald,
It
looks like just the archivelog was not going into the correct directory,
right? But then you did *not* include a format clause for the
archivelog.
Looking at the docs, it looks like you should change the
following:
backup database
format'D:\backup\oracle\Hotbackup\rman_d%d_t%t_U%U.bak' plus
archivelog;
to
backup database
format'D:\backup\oracle\Hotbackup\rman_d%d_t%t_U%U.bak' plus archivelog
format
'D:\backup\oracle\Hotbackup\arcs_d%d_t%t_U%U.bak'
Good
Luck!

RE: RMAN backup with MULTIPLE CHANNELS ......
Babu - We allocated multiple channels on an RMAN disk backup and the backup time was reduced. I would suggest you try to figure out where your bottleneck is. Are you writing to multiple tapes? Actually, RMAN has several features to keep the tape streaming, you may want to look at these. If your tape isn't streaming, you might get more throughput from a single tape drive than you are now.

RE: RMAN backup with MULTIPLE CHANNELS ......
Dennis, Thanks for your reply. Iam taking tape backup with 3 channels as we have multiple tape drives. I don't know where the bottleneck is. In the RMAN output I see it is using all the three channels simultaneously with 10 datafiles per channel. But Iam not getting the throuput. It is taking the same amount of time as it used to take for single channel. I don't know where to look, and don't know how to fix the problem and take advantage of multiple channels. -- Babu -Original Message- Sent: Thursday, February 20, 2003 9:39 AM To: Multiple recipients of list ORACLE-L Babu - We allocated multiple channels on an RMAN disk backup and the backup time was reduced.

RE: RMAN backup with MULTIPLE CHANNELS ......
One possibility is that the backup job is already maxing out the network connection between the client system and the Veritas NetBackup master server and/or media server. If you have a 10megabit network and LTO drives, the network will never be able to keep the tapes streaming. Adding 3 channels won't help if your network can't keep up. I'm speculating here, as you don't really supply enough info about your environment.

Just be sure and post it to the list. There are folks here with more NBU/RMAN experience than I. Network between database server, master server and media server. 10Megabit, 100 Megabit, Gigabit? Concurrent backup jobs? # of Tape drives dedicated to this backup? Type of drive? LTO, DLT, Super DLT?

Hi, I looking at implementing RMAN backup and recovery to disk (fast disk) on a high avail. system...so recovery time is crucial.. Anybody know how fast I might restore a full backup of a 600gig to a Terabyte database. The machine probably will have 10+ cpus HP machine and EMC disk although the backups will probably sit on a fast SAN. There will be 12Gig of fast memory... 200,000 users...max 10,000 concurrent, 100MB io card. IF anyone has done it...what speeds could you obtain with RMAN from Disk?

RE: RMAN backup
Joe - Which type of RMAN backup are you doing? If you are doing RMAN datafile backups, then the size of your datafiles matter. If you are using the RMAN backup command, you are creating RMAN backup pieces. RMAN backup pieces contain parts of several data files, and you can't control that. You can control the maximum size of each piece. Dennis Williams DBA, 40%OCP Lifetouch, Inc.

Re: RMAN backup to remote dir. - how ?
Use map network drive on your target machine and define the drive as a
directory on your recovery machine.
I mean: map drive K on the target machine as f:\backup on the recovery
machine.
Then backup to drive K.

Re: RMAN backup to remote dir. - how ?
Well since you haven't gotten a reply from anyone else yet, I'll take a
crack at it, but I don't use Oracle on Windows so I may be totally off
base.
I'm assuming that your f drive is a mapped drive to your catalog db
server. I don't recall the details, but I believe that just because you
have mapped a share that you can see, doesn't mean that Oracle can see the
same mapped share. I think Oracle has fewer privileges than necessary to
see the mapped drive. I don't recall the solution, but I'm pretty sure it
was covered on MetaClunk.

Re: RMAN backup and restore Q?
Hi
My problem went away when I did a startup mount of the database.
I have Rman user in TEST2 just for testing purposes (same username password
on target catalog is easier with ctrl C ctrl V)
One more question if I may.
Do you or anybody else have an example of a very complex rman command(most
of the features used) and an example of cloning a database on the same host
with renaming of the log datafiles? Documentation explains a lot but is
very limited in the examples and the syntax errors are easy to make.

What version of the database are you using? My info here is based on
8.1.7.
I connect to my databases as internal to do the backups. I fire up RMAN
with either one of these commands:
rman target / catalog rman/rman@test1 (SID must be set correctly)
rman target internal/pwd@test2 catalog rman/rman@test1
I'm not sure why you have an rman user in test2, unless you set up a second
catalog so that you can backup your first catalog.
To test your restore, shutdown test2 and delete all the .dbf, .log, .arc,
and .ctl files. Then startup nomount the test2 database. Then try this:
rman target internal/pwd@test2 catalog rman/rman@test
run {
allocate channel ch1 type disk;
restore controlfile;
alter database mount;
restore database;
recover database;
alter database open resetlogs;
}
If you did a hot backup, you may need your archivelog backups. This
command backs up the archivelogs:
run
{
allocate channel ch1 type disk format '/bkup1/oracle/%d/arc_s%s_p%p_%t';
set limit channel ch1 kbytes=100; # Limit sets to 1 Gb.
backup archivelog until time 'sysdate-1/24' delete input;
backup archivelog from time 'sysdate-1/24';

I have created the catalogs and registered the database with the catalog.
I than mad a full backup of the database TEST2 (is in Archivelog mode)

which created the database backup OK
When I try the restore however I get ORA 19753 cannot obtain exclusive

RESTORE*
rman EOF
connect target rman/rman@test2
connect catalog rman/rman@test1

Checking the database TEST2 showed a shared MR lock in the v$lock view on

RE: RMAN backup and restore Q?
Jack,
What is the status of your target database?
Try having it in startup mount status rather than startup open.
The other thing you should do is to backup your control file (using Rman)
with every database backup. I do this as my last step with every backup so
that the latest changes within the control file are also saved.
Hope this helps

Re: RMAN backup and restore Q?
What version of the database are you using? My info here is based on 8.1.7.
I connect to my databases as internal to do the backups. I fire up RMAN with either
one of these commands:
rman target / catalog rman/rman@test1 (SID must be set correctly)
rman target internal/pwd@test2 catalog rman/rman@test1
I'm not sure why you have an rman user in test2, unless you set up a second catalog so
that you can backup your first catalog.
To test your restore, shutdown test2 and delete all the .dbf, .log, .arc, and .ctl
files. Then startup nomount the test2 database. Then try this:
rman target internal/pwd@test2 catalog rman/rman@test
run {
allocate channel ch1 type disk;
restore controlfile;
alter database mount;
restore database;
recover database;
alter database open resetlogs;
}
If you did a hot backup, you may need your archivelog backups. This command backs up
the archivelogs:
run
{
allocate channel ch1 type disk format '/bkup1/oracle/%d/arc_s%s_p%p_%t';
set limit channel ch1 kbytes=100; # Limit sets to 1 Gb.
backup archivelog until time 'sysdate-1/24' delete input;
backup archivelog from time 'sysdate-1/24';
}

Re: RMAN Backup Size
I believe that RMAN only backs up blocks that have been allocated to an oracle object - index, segment, table, etc. If the block is in a datafile but not in use by an oracle object (that is, the block is free), then RMAN doesn't backup those blocks.

RE: RMAN Backup and Recovery
Don, You don't state whether or not you're getting the archived redo logs at each Level 0 and 1 backup as well as the 3 archive-logs-only backups. If not, you probably should. Also, if recovery speed will be important, those incremental backups should be cumulative, not differential. However, cumulative takes more storage than differential - always the tradeoffs!

RE: RMAN Backup and Recovery
Hi, In one of our production site, I implemented RMAN backup and recovery scripts. I did the following way. Take a full backup using RMAN, the following things will be backed up datafiles,Archive logs files, controlfile. I didn't use the catalog database. I used the database's controlfile instead. After this for next 6 days take incremental backup ie archivelog files and control files. Once in a week(lets us say Sunday) we are taking a full Database online backup. From Monday to Sunday incremental backup. Let us assume that my db crashes on thursday. I restore the full database backup from Sunday and start applying the incremental backup till wed and the rest of logs that are generated(provided they are there) then my I can bring the database upto the point where it had crashed. This particular method was tested and it is successfully running in the production site. The DBA now in the production site has managed to take the incremental backup twice a day(early morning and late evening) he schedules them copies the files from the disk to tapes and keeps them. Recovery depends what type of failure u face. In this db controlfiles,redolog files are mirrored from OS. The load is easily distributed.It has four HDD controllers with a combination of RAID 0 and RAID 1, with MSCS in WinNT. RMAN saves time and disk space. If we use the traditional Oracle backup utility(ALter tablespace tbl begin backup) we need the exact space that is occupied for Datafile. If we integrate with Media Management software with RMAN, then u can directly write into tapes. -- On Wed, 21 Mar 2001 07:22:01 Jack C.
