RMAN merge backup with compression

Hi All,
Os : solaris 10
db: 10.2.0.4
as of now as per our backup strategy we are taking RMAN levle 0 weekly and daily incremental backup as compressed.
we are planning to take RMAN merge backup like below
For full backup on sunday
backup incremental level 0 AS COPY tag 'DEMO_MERGE_DB' database ;rest of the days
BACKUP INCREMENTAL LEVEL 1 FOR RECOVER OF COPY WITH TAG 'DEMO_MERGE_DB' DATABASE;My question is , while taking as merge is there any option to compress the backup.
i have gone through but dint see any info regarding this.
Please help...
Thanks in Advance

merge backup , updated backup and image copy are these things are same or any difference inbetween..Image copy of backup copy of the data file
merge backup means that you take incremental backup of data and merge it with the image backup copy of the datafile so that backup copy is updated all the time and in case of recovery, you don't need to apply all archives since backup copy because his copy is already up to date till the time of last merge backup.
Now your image copy backup is an updated backup because it is keep on updated with the incremental backups using merge backup strategy.

MSSQL 2008 R2 - 32bit, TSQL backup with compression, error: There is insufficient system memory in resource pool 'internal' to run this query

Hello,
I would like to ask you about advice.
We have MSSQL 2008 R2, 32 bit. Memory is 4GB, split into 2GB for Windows and 2GB for applications. Database has recovery model simple because we have replicated data into other servers ( 2 ). Contemporary we work with 2 servers. Max memory for MSSQL is 2048
MB.
We set the backup as follows:
USE MSDB
GO
DECLARE @JMENO_ZALOHY VARCHAR(120)
SELECT @JMENO_ZALOHY = 'E:\backup\BackupSQL\1 Pondeli\DAVOSAM_'+ convert( varchar(2), datepart( hh, getdate() ) ) + '00_DEN_DIFF.bak'
SELECT @JMENO_ZALOHY
BACKUP DATABASE [DAVOSAM]
TO DISK = @JMENO_ZALOHY
WITH INIT, DIFFERENTIAL, CHECKSUM, COMPRESSION
GO
Every second or third day in log there is error message: 'There is insufficient system memory in resource pool 'internal' to run this query' Accurate in time of backup. The error is still repeat, majority in working hours.
Today I have found out, that problem is probably in compression of backup. Because if I removed word: compression, a backup normally runs without error.
Question: Is my hypothesis correct that problem is in backup with compression?
Thank you David

Hello, today evening I have ran backup command bellow. All is OK. Probably MSSQL has cleaned memory. Next attempt I will try in peak next week.
Since time I have removed word compression, in error log is not any error.
I have checked memory as soon as memory gets on top, it is about 1.707 GB the MSSQL writes into log this messgages:

Does RMAN in 10g Enterprise Have Backup with *Compression* ?

hi RMNA experts,
I use the Enterprise edition of 10g. Using RMAN for database backups.
Can you request compression in an RMAN backup - to get a smaller backup file?
Thanks, John

Yes you can. Here is the script.
run {
allocate channel ch1 device type disk;
backup as compressed backupset incremental level 0 format '/u03/rman_backup/RMAN_DBF_TST<%s:%t:%p>.bkp' database;
sql 'alter system archive log current';
backup as compressed backupset format '/u03/rman_backup/RMAN_ARCH_TST<%s:%t:%p>.bkp' archivelog all delete input;
backup as compressed backupset format '/u03/rman_backup/RMAN_CTL_TST<%s:%t:%p>.bkp' current controlfile;
Regards
Asif Kabir

RMAN online backup with dbconsole.

I want to run an online (hot) backup of a 10g enterprise edition database using dbconsole. There is no option for this on the web page that I can see. I thought I could trick the software by selecting 'whole backup' and then edit the RMAN script and enter the command 'backup database plus archivelog'. That command was documented as the way to run an onlne backup in the Oracle Press book 'Oracle Database 10g, RMAN Backup & Recovery'.
But there was a message stating that the database would be brought down during the backup, obviously ignoring the command mentioned above.
1. Can I perform a hot backup with dbconsole?
2. If so, how?

Rman merge backup

I read the Incrementally Updated Backup In 10G [ID 303861.1]
It very good RMAN 10g features .
I have level 0 impage copy and t increamental backup in the disk
another increamental backup will run tonight
Assume that one of my databasefile is corrupt
how to recover in the merge database backup
what is the base I will start
Oracle 10.2.0.5

It's not really a "merge database backup" but an "Incrementally Updated Backup".
If you lose only a single datafile in your database you can use
RESTORE DATAFILE n FROM DATAFILECOPY
RECOVER DATAFILE nso RMAN would copy only that datafile from your Incrementally Updated Backup after which you still need to RECOVER DATAFILE to bring it uptodate (synchronise) with the rest of the database.

That´s all i got on screen. Where is the rman log, so I can check what was going? The same script is running well on my 10gR2 EE at RHEL3. Tried without the "compressed" came out the same hung.

RMAN backup with smallest backup size

Oralce 11g2 on Redhat 5. The diskspace is our tightest resource, and we want to an incremental backup with level0 on Sunday and level 1 every week days and Saturday. I am to use the comamnds to do the job--Sunday
backup incremental level 0 tag 'level_0' database plus archivelog;
--Other days
backup incremental level 1 database plus archivelog delete all input;I do not think this is the best practice nor produce smallest backup files.
What are you comments and opinions. Thanks

Pavan, Thank you for reply. Here are the info requested
what is size of DB ??
~250GB, including UNDO and TEMP. It is a dev database and not very big. But we have total 800GB disk space. After setting some housekeeoing folders, and allow some space for data growth, it leaves 180GB for flash_recovery_area.
what would be max size of archive logs generated per day ??
Variable from less than 1 GB to 12 GB
Are you taking backups to tape or Disk ??
Disk. In the 180GB flash_recovery_area, Current backup size is 152GB. If a backup fails to delete obsolete files, the next backup will fill the flash_recovery_area.
Provide the Rman configuration information ??

Rman backup with corrupted block

Hello,
Firstly - I have problem on non-production database 11.2.0.1.0, so I am not deeply worried about data. But I need to understand what happened with database backups and how to prevent such things in future.
So - I have EM scheduled weekly full backup and daily incremental backups. Later there was problem with hardware and some corrupted blocks in database were found. The weekly backup ran without error and obsolete backups were deleted. Now it is not possible to "recover corruption list" because no backup without corruption exists (RMAN-06023: no backup or copy of datafile 6 found to restore). I am not worried about the lost data, but I need to find out how come the backup contains corrupted block.
I have checked the data file using dbv utility
DBVERIFY - Verification starting : FILE = /opt/oracle/oradata/orcl/users03.dbf
DBV-00200: Block, DBA 27525766, already marked corrupt

Highest block SCN            : 2156227446 (1.2156227446)As you can see the datafile 6 - user03.dbf has errors. Also backups now contain errors.
1) So how is it possible that the EM scheduled backup ran without problems and the backup now contains corrupted blocks. How to prevent this in future ? I know there is setting MAXCORRUPT. How can I check its current value ? How can I configure it using EM scheduled backups ?
2) Secondly, meanwhile I studied the RMAN commands. So I have suspended EM backup jobs, and executed follwing command. And backup ran without error again. How is this possible, if data file users06.dbf has corrupted block ?
Thanks !

RMAN Automatic backup/recovery with oracle fail safe, windows cluster

Hello,
I have question,
1) Whether it is possible to do "RMAN Automatic Backup and recovery" in environment as ?
Environment: -
a. Windows clustering with windows server 2003 Enterprise Edition R2 (Two Node Clustering)
b. Shared disk ( RAID )
c. Oracle 10g standard edition one
d. Oracle fail safe v3.3.3 (for redundancy)
Here we have single oracle instance operating on single database whose files are located on shared disk.
2) If answer to above question is yes please specify if there is some good documentation to it.
Any help regarding this will be greatly appreciated.
Thanks in advance,
Rahul

You just need to make sure that the RMAN scripts are always able to connect to the target database instance whether instance runs on cluster node 1 or cluster node 2
here, If oracle services(resources) will shift from Node1 to Node2 (due to media or any failure) during RMAN Backup then there will be break in connection, will it destroy my backup or will it get started automatically without any harm?
and also I want to know,
Do we need to setup another server which will have RMAN backup script running?

Rman backup with standby database

Hi All,
I am looking for some suggestions for rman backup with standby database with datagaurd but no active DG. I wanted to do a rman tablespace backup. but I am stuck at sql 'alter system archive log current' in rman with standby as target. which gives following errors with or without noswitch clause
RMAN> sql 'alter system archive log current noswitch';
sql statement: alter system archive log current noswitch
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of sql command on default channel at 10/05/2013 18:15:12

Recovery Manager: Release 11.2.0.1.0
Oracle databaes Release 11.2.0.1.0 64 bit

Secondly, do I need to cancel manged recovery while taking rman backups on standby.
I scanned thru MOS but could find solutions for rman with active DG.
Thanks in advance

Howto make a consistent RMAN backup in an Standby database in Active DataGuard mode (Doc ID 1419923.1)

RMAN Backup with ASM and Standby in place

Hi All,
We are planning to upgrade our database from 10.2.0.2 to 10.2.0.3. We have ASM as storage on primary and phisical standby is in place.
I want to make a cut of point for backup, i.e if I restore till that poit on primary standby should continue to work. I need not create standby.
We are using rman for backup and primary db uses asm for data,archive and redolog storage.
I have a online complete db backup at 12:00PM. At say 6:00pm i take primary down and apply all archives on standby and cancel recovery on standby along with taking it down. On primary i mount db and take controlfile backup and all archive log backup using rman.
Now i continue with upgrade and many more changes on primary. I will not touch standby. We decide to revertback at 10pm on primary. If I wan to return back to 6:00pm state on primary and standby.
I believe I will restore controlfile backup taken at 6:00pm with db in mount phase. Restore dbfiles from online backup and recover using archives.
My question is do i need to open with resetlogs? Then I will lose my standby which was up to date at 6:00pm. Can I not backup redofiles at 6:00pm with db in mount phase and i restore them then i need not open with reset logs and my stnadby will continue from that point.
Please guide me..Is there way to backup redologs when db is in mount phase and using asm for storage using rman.

There are quite a bunch of steps involved and you need to do some documentation reading.
Do you plan to create the test database on the same machine or different RAC system?
Which version of Oracle are you using? What OS?
There is plenty of information on the web if you search for "duplicate database RAC ASM". Did you try?

Rman archivelog backup fails with rman-03002,ora-19563

Hi,
D:\ Oracle- -\BIN\RMAN TARGET / NOCATALOG
RMAN> backup archivelog all;
RMAN-03002: Error with backup command on 06-25-2013
ORA-19563: Header-Validation is not successful.
fails with the given errors.
11.2.0.2 PROD DB on Windows Server 2008 R2 Enterpriise.
When I issue BACKUP INCREMENTAL LEVEL 0 DATABASE; it works fine. but with archivelog it is creating problems. Unfortunatly, I have not found exactly the same problem on google and on Oracle support.
The DB is using INIT.ORA and last time when I switched the mode to archive log mode I set the parameter like SCOPE=MEMORY as SPFILE was not in use and ALTER SYSTEM with SCOPE=BOTH FRA destination and size, but after the DB restarting of course that setting is gone and I am having these problems.
Please suggest.
Thanks a lot.
Best Regards,

Hi,
Thanks a lot.
I don't think that archivelogs were relocated, except I changed the location yesterday.
As I wrote at the start that because of INIT.ORA file being in use instead of SPFILE. I set DB_RECOVERY_FILE_DEST, DB_RECOVERY_DEST_SIZE after changing the DB mode to ARCHIVELOG, but DB was restarted by somebody else, and as the parameter changing was NOT PERMANENT, it rollback.
LOG_ARCHIVE_DEST was set to d:\oradata\db with archivelog mode but db_recovery_file_dest and size was set to 0. Now here, I have no idea that whether archivelogs were not being backed up or deleted physically, but I guess that as log_archive_dest parameter is deprecated and mode is set to archivelog with no real ARCHIVELOG DESTINATION. Please correct me if I am wrong or totally wrong :-)
I performed DELETED EXPIRED ARCHIVELOG ALL, and it deleted 49 EXPIRED objects.
Now CROSSCHECK ARCHIVELOG ALL and LIST ARCHIVELOG ALL shows nothing.
LIST BACKUP OF ARCHIVELOG ALL has of course those 49 archivelog gap.
Could you please tell the impacts of those 49 missing archivelogs. Retention policy is set to 14 days. I mean the risk is for 14 days right? As anyhow, the older backups are being DELETED according to retention policy of RMAN.

Restore incremental backup with rman

Dear Friends
can u tell me how to restore an incremental backup with rman? i backup my rman with statement below :
1. backup full database format '/oracle/PRD/sapbackup/%U';
the results was :
-rw-r----- 1 oraprd dba 19006996480 Jun 10 12:08 0ojiit4n_1_1
-rw-r----- 1 oraprd dba 12746752 Jun 10 12:08 0pjiiu6b_1_1
2. after that i do incremental backup :
backup incremental level 1 cumulative database format '/oracle/PRD/sapbackup/%U';
the results was :
-rw-r----- 1 oraprd dba 173400064 Jun 10 13:44 0ujij2k0_1_1
-rw-r----- 1 oraprd dba 12746752 Jun 10 13:44 0vjij3qc_1_1
what statement i need to run for restore the incremental backup?

run{
ALLOCATE CHANNEL c1 DEVICE TYPE DISK;
RESTORE DATABASE;
RECOVER DATABASE;
The above command will restore your database from the last good RMAN backup. Your last backup is incremental level backup as you posted. The above command will fullfill your requirements

Catalog backup not compressed with Lightroom 6

Lightroom 6 is said to compress the catalog backup into a zip file.
When I try this with a small test catalog it works fine.
However when I backup my real catalog (75 000 photos, 7.5 GB) the file is not compressed. LR6 behaves exactly as LR5.
I tried several times but it is always the same.
Did someone meet the same problem ?
Any advice ?
Thanks.
Michel (Paris)

Thank you Ian for your answer.
However I don't think I misunderstood how Lightroom backup works. Maybe I was not very clear in my explanation (English is not my mother tongue !).
I run a test with a small catalog (test_backup.lrcat), which I created just for this purpose. In this case the catalog backup is compressed in a zip archive
However, when I open Lightroom with my actual catalog (lightroom-6.lrcat), then the catalog backup is not compressed (it's just a copy of the catalog).
I don't understand why LR6 does not compress the catalog backup in the last case.

Incremental RMAN backup and compression

Does RMAN compress the data for the incremental Level 0 and Level 1 backups. More specifically - Can I use Advanced compression if olny use incremental backups ?

you would use the comfigure command to use zlib which is does not compress as well as bzip2 which does not require the advanced compression option, but zlib does not consume as much cpu as bzip2.
now for the backup you have 2 options. you can configure backupsets to compress
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET ;
or it using table
CONFIGURE DEVICE TYPE sbt BACKUP TYPE TO COMPRESSED BACKUPSET ;
Then do you backups as backup sets
database
backup as backupset incremental level 1 tag hot_1_${DTE} DATABASE NOT BACKED UP SINCE TIME 'SYSDATE - .6';
archivelogs
backup as compressed backupset format '${INST_LOWER}_Archive_%d_%s_%p_%t' archivelog all not backed up 1 times ;
