RMAN - Schema level backup ??
We have a production system in which one schema is getting bigger day by day(40GB).
We want this schema in our development instnaces once in a week atleast.As export for this is taking time we want to go for rman setup for faster process.
1)Will rman backup speed up the process ?
2)Is there any way we can take the rman backup for a schema and not for the whole database.
3)If yes what are the steps for this setup and steps to use this in the develpment database?
Production is on hp-ux and dev on windows.
1)Will rman backup speed up the process ?It depends. If they will be backuped only 40Gb, will be relatively fast.
2)Is there any way we can take the rman backup for a schema and not for the whole database.Schema No, but if the schema objects is in a single tablespace one, can be make the tablespace backup
3)If yes what are the steps for this setup and steps to use this in the develpment database?Follow the steps to backup the tablespace.

RMAN 0 level backup failed while releasing channels at end.
In RMAN 0 level backup, when it's about to finish, reports an error as releasing channels. It backed up about 98% datafiles.
Is this backup is usable. As we can not affort to take backup again as it's a big terabyte databse.
Please suggest.
Thanks in advance.
Aj.Do you have release stmts in the script
From 9i onwards oracle Release the channels automatically upon backing up, so you can remove the release channel lines if you have and try it -

Thanks.rman is only concerned with backup of physical blocks of the data files. That is a few layers of abstraction below the concept of 'schema'. rman doesn't give a flying fig about what is on a given block. It only cares if the block has been/needs to be backed up, and where within the file it came from (backup) and goes to (restore). -
Backup RMAN Incremental Level 1 without Level 0 - 10gR2
Hi,
I'm a bit confused after some tests.
The Question: It's mandatory to perform backup incremental level 0 before the level 1 using Oracle 10gR2 ?
On Oracle 11.2 it's mandatory but on Oracle 10.2.0.5 I don't know.
Test on 11.2. If doesn't exists level 0 rman take care about it and perform automaticaly level 0 before level1

...Docs said:
Incremental backups capture only those blocks that change between backups in each datafile.
In a typical incremental backup strategy, a level 0 incremental backup is used as a starting point. A level 0 backup captures all blocks in the datafile.
So, on Oracle 10.2.0.5 this not happen like on 11.2:

Levi PereiraHi Gokhan,
Thank you for point this.
After spending a time studying about this I find out this:
Your expanation apply only in Oracle 10gR1/R2.
Because there is differences between RMAN Version 10gR1/R2 and 11gR1/R2 about Incremental Level 1 and this confuse me.
Oracle 10gR1/R2 run only one backup incremental level 1 even if level 0 not exists .
Oracle 11gR1/R2 run two backups incremental if level 0 not exists. i.e level 0 first and after that level 1.
Oracle 10gR2
If no level 0 backup is available, then the behavior depends upon the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks changed since the file was created, and stores the results as a level 1 backup. In other words, the SCN at the time the incremental backup is taken is the file creation SCN.
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup004.htm
Thats means wich RMAN run level 0 with name level 1. (i.e: Only one Backup) This is confuse.
Oracle 11gR1
If no level 0 backup is available in either the current or parent incarnation, then the behavior varies with the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks that have been changed since the file was created. Otherwise, RMAN behaves as it did in previous releases, by generating a level 0 backup.
http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmcncpt.htm#BRADV89500
Oracle 11gR2
If no level 0 backup is available in either the current or parent incarnation, then the behavior varies with the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks that have been changed since the file was created. Otherwise, RMAN generates a level 0 backup.
http://download.oracle.com/docs/cd/E11882_01/backup.112/e10642/rcmcncpt.htm#BRADV89500
Thats means wich RMAN run (automatically) level 0 first after finish level 0 backup RMAN run level 1 backup (i.e Two Backups). This seems right.

If RMAN incremental level-1 backup fails...
Hi there,
I have a question. If the RMAN incremental level-1 backup fails, will the next level-1 backup attempt take backup of all changes since last successful level-0 OR level-1 backup?
Best regardsHi,
I have a question. If the RMAN incremental level-1 backup fails, will the next level-1 backup attempt take backup of all changes since last successful level-0 OR level-1 backup?
Check the V$BACKUP_SET dictionary to confirm whether the last backup has been touched by data dictionary. If the failed incremental backup is picked up then the previous incremental backup will be required in case of the next DIFFERENTIAL INCREMENTAL LEVEL 1 backup.
But to be on safe side , it is recommended you take a LEVEL 01 CUMILATIVE INCREMENTAL backup from Level 0 till date. So that the recovery process can go through even if the previous backup is not valid.
Thanks &

If I need a full rman restore which backups will it use?
Hello,
I have a database 11.1.0.7 with 8TB. Block change tracking is enabled.
At the weekend I take level 0 backup and during the week level 1 cumulative.
For some weeks the level 0 backup is failing, so I only have level 1 cumulative backups taken every week day with a 4 weeks old level 0 backup.
If I need a full rman restore which backups will it use? Will it be the last level 0 backup with the last level 1 cumulative?
I ask this because grid crontrol tells me that the recent level 1 backups input size is smaller than last week level 1 backups and in between I dont have any level 0 sucessfull backups. Shouldn't the input size of level 1 cumulative increase until the next level 0 backup ?
The grid reports:

Validating Backups Before Restoring Them
You can run RESTORE ... VALIDATE to test whether RMAN can restore a specific file or set of files from a backup. RMAN chooses which backups to use.
The database must be mounted or open for this command. You do not have to take datafiles offline when validating the restore of datafiles, because validation of backups of the datafiles only reads the backups and does not affect the production datafiles.
When validating files on disk or tape, RMAN reads all blocks in the backup piece or image copy. RMAN also validates offsite backups. The validation is identical to a real restore operation except that RMAN does not write output files.
You can monitor what RESTORE VALIDATE does.
Make precautions, so you do not damage the production DB!!!

We have an incremental level-1 backup Mon-Sat and cold full backup on Sundays with retention policy of 7 days. While troubleshooting some backup issues (space issue, expired backups) I ran the following commands and trying to understand the output.
RMAN> report need backup database;
RMAN retention policy will be applied to the command
RMAN retention policy is set to recovery window of 7 days
Report of files whose recovery needs more than 7 days of archived logs
File Days Name
100 146 /orahprdidx/hprd/psindex05.dbf
RMAN> report unrecoverable;
Report of files that need backup due to unrecoverable operations
File Type of Backup Required Name
RMAN> report need backup days = 7 database;
Report of files whose recovery needs more than 7 days of archived logs
File Days Name
100 146 /orahprdidx/hprd/psindex05.dbf
RMAN> report obsolete recovery window of 7 days;
no obsolete backups found
RMAN>
I looks like I need 146 days worth of archive log files to recover the psindex05.dbf. If so, what I could do to bring that into the 7 days policy?
The database is fine, I am not trying to recover the database.
This was setup by someone and now I am taking over with minimum RMAN experience.
I appreciate any help in this subject.The datafile was offline. I guess it was created my mistake and hanging in there. Once I do the cleanup it should go away.

What to do if there is abrupt termination of RMAN during a backup session
Hi All,
I am trying to automate the Level 0 and Level 1 backups which we ought to take. Following the is the RMAN related part of it for L1 backup:
CONFIGURE CONTROLFILE AUTOBACKUP ON;"
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '${BKP_LOCATION}/${LType}_%F';"
run {"
allocate channel c1 type disk;"
backup"
incremental level 1 cumulative tag = $BTAG"
format '${BKP_LOCATION}/${LType}_%d_set%s_piece%p_%T_%U.bkp'"
(database include current controlfile tag $CTAG) ;"
sql 'alter system archive log current';"
sql 'alter system archive log current';"
backup archivelog from sequence ${CSEQ} tag $ATAG"
format '${BKP_LOCATION}/${LType}_Arch_%d_set%s_piece%p_%T_%U.bkp';"
release channel c1;"
exit;"
In the above snippet, the variables are substituted for within a shell script and then put into a command file for RMAN. I am a novice in the backup and recovery. I got above piece of code from someone working on RMAN and built my automation logic around it.
The script works fine and I am trying to build to script level recovery feature around it. My question is:
-- What happens if I invoke the script, the backup session starts and then there is abrupt termination of the RMAN session either because of losing the db connection or receiving an interrupt signal or a kill signal or some other weird reason.
-- What if I re-invoke my script? Will it start from the point where it was stopped earlier or would it start from the point where we had last successful Level 1 backup completed?
Thanks in Advance.Hi user781131,
What happens if I invoke the script, the backup session starts and then there is abrupt termination of the RMAN session either because of losing the db
connection or receiving an interrupt signal or a kill signal or some other weird reason?The backup set which rman was creating is not commited due to the abnormal termination but all succesfull backup sets can be used.
What if I re-invoke my script? Will it start from the point where it was stopped earlier or would it start from the point where we had last successful Level 1 backup
completed?In your backup script you do not use the < NOT BACKED UP SINCE TIME > clause so it will again do a level 1 backup off all datafiles.
See:
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta009.htm#i1017236
This option is a convenient way to back up files that were not backed up during a previous failed backup. For example, you back up the database, but the instance fails halfway through. You can restart the backup with the NOT BACKED UP SINCE TIME clause and avoid backing up those files that you already backed up. If AS BACKUPSET is set, then this feature is only useful if RMAN generates multiple backup sets during the backup.

Tycho

RMAN CUMULATIVE LEVEL 0 to tape WORKS BUT NOT LEVEL 1 RMAN
Hi All:
I have this saturation My rman cumulative level 0 to tape works everytime but when I try to do level-1 rman backup it failed and it never works. From the rman log, I posted below, it looks like the MML is having a problem. My question:
1. IF this is only MML problem. Isn't that both level-0 and level-1 will failed? Why only level-1 is having the MML problem not level-0?
2. What is RMAN doing different between level-0 and level-1?
ORA-19502: write error on file "cum1_TNLTST8_9qf8fef5_1_1", blockno 1 (blocksize=51
2)

Any suggestion or comment are welcome!Hi Guys
I have a customer where I am supporting a Veritas Netbackup environment and found similar errors on 3 of their oracle databases during backups. The problem is intermittent and if you keep on trying you will get a successful backup. I am not skilled in Oracle and would like some pointers.
Thanx -
NOLOGGING with CTAS and RMAN's Incremental backup
DB Version: 10.2.0.4
OS : AIX
We use RMAN for our backup scheduled via cron.
Retention Policy : REDUNDANCY 1
Type : Incremental On 31st of every month, in most of our schemas, we recreate lots of tables using CTAS.
Because of the size , CREATE TABLE statements take a long time. Since we run on Standard edition, we can't use PARALLELISM.
NOLOGGING is the only option to improve the performance. But we are worried about the redo not being generated for these tables and the potential loss of data in case of a crash.
Currently we take a LEVEL0 backup every wednesday and Sunday nights and LEVEL1 backup on the rest of the days.
I know that everything will be backed up on LEVEL0. But, what if 31st falls on a day where only LEVEL1 backup occurs. We'll only be safe until the next LEVEL0 comes along.
Any workarounds for this?When you write "we need" you make an assumption not supported by the facts.
The fact is that you need to refresh the data ... you do not need to recreate the table.
This is just one better solution:
http://www.morganslibrary.org/reference/materialized_views.html
there are others too. But not knowing your version number, and you still have not really stated the business case, I can not advise which would be the best. But it is safe to say there is no way on earth I would do what you are doing based on what you've posted. For example why at the end of each day can't you copy that day's rows to a predefined table spreading the load out over all 30 days and then, at month's end truncate the current table and rename it then rename the already loaded staging table. The swap could be done in a few seconds with essentially no overhead. -
Will RMAN remove invalid backup pieces from Backup tests?
DB Version: 10.2.0.4.0
Thinking that Level1 backups don't take much time, In production, I was testing a Level 1 bkp (I took a level 0 bkp of our 700gb only yesterday).
But, the end users were complaining that system has become very slow. So, i've cancelled the LEVEL 1 backup.
Now i can see 5 backup pieces wasting some space.
I know that RMAN removes expired backup like
delete expired backup;But, how do i script RMAN to remove files mentioned above ie.files from a backup that was aborted halfway through ?Hi Insignificant
But, how do i script RMAN to remove files mentioned above ie.files from a backup that was aborted halfway through ?If you can locate them on the OS level you could remove them with OS commands.
For backup pieces containg datafiles use <crosscheck backup;> followed by <delete expired backup;> with rman client.

Very first step in configuring RMAN for a Backup
DB version:10gR2
I am a DBA supporting applications development and i am not familiar with RMAN. This weekend we are going to Patch 10.2.0.1.0 to 10.2.0.3.0. Before that i am going to take a backup of the entire Database containing around 57 schemas(total of around 600gb).
We don't have Tape drives. I am going to backup this up on three filesystems in the same machine. This instance is not running on ASM. What is the first step i should be doing in configuring RMAN for a backup?
Edited by: user10583227 on Jan 27, 2009 4:50 AMBe careful, three filesystems doesn't necessarily mean the use of three channels. Could be more...could be less.
Are you in a position to shutdown the database? If not, you'll also want to backup the archivelogs with BACKUP DATABASE PLUS ARCHIVELOG. You may also consider creating a Guaranteed Restore Point which would allow you to rollback your database in minutes if the upgrade fails. -

EXPORT at schema level, but exclude some tables within the export
I have been searching, but had no luck in finding the correct syntax for my situation.
I'm simply trying to export at the schema level, but I want to omit certain tables from the export.
exp cltest/cltest01@clprod file=exp_CLPROD092508.dmp log=exp_CLPROD092508.log statistics=none compress=N
Thanks!Hi,
Think in simple first.. you use the TABLES Clause..
Example.
exp scott/tiger file=empdept.expdat tables=(EMP,DEPT) log=empdept.log
In case if you scehma contains less number of tables.. !!
Logically if you have large number of tables, I say this solutuion might work ...all around... alternative solutions to solve the problems.. If you have hundered of tables... in your schema....
Try to Create a New Schema and using CTAS create a tables which are skippable in the Current Scehma.
Do an Export and once the Job Done.. you recreate the backup fom New schema
and Import to DB (Destinaiton)

include current controlfile;
2) Restore / Duplicate
Have database orcl2 which is on the same server as ORCL1. Performing a no catalog recovery.
