is it appropriate to take RMAN BACKUP in DG?
I have following query in Dataguard ..
If I want to take Rman archive log backup with delete input command , how the archive logs will be copied to standby database
For eg
I am taking archive backup as
RMAN>backup archivelog all delete input;
here consider few archives are not copied to standby database (due to nw issue) then how standby will receives these missing archives as those are deleted by rman backup at primary side.
I am not getting any document related to above query.
I have One Production and one logical standby database . Due to tape problem we are unable to take backups of primary . And due to business , we cannot take back up on disk in hot period(Bank database ) .
If i take logical standby database backup(level 0 ) using RMAN , then will i be able to restore it on production dtbs (In case Production down) ? . Logical standby is in sync with primary .
I use windows 2003 server, oracle 10.2.0.4.0.My question is related to maintaing a standby database
1. Do we need to take RMAN full backup of standby database on a regular basis? At the moment I dont take backups of standby database.
2. I have FRA on standby database. The archivelogs from primary go to FRA on standby. I delete my archivelogs as follows:
DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-3';
Though the archivelogs are delete there are still empty folders of archivelogs that are not deleted. How to get rid of them automatically.
I am trying to create the Standby database using RMAN.
I have first created an auxiliary instance followed by the password file for the instance and the registering it it listener.
Below are the parameters of the pfile of the standby database and followed by the command issued at the RMAN prompt.
PFILE parameters [STANDBY]
orcl.__db_cache_size=293601280

How to create a standby database without rman and with the rman..?
View 1 Replies View RelatedCan i setup physical standby without RMAN? I want to create a fresh single physical standby without RMAN .. If i copy all files in another system and take the controlfile from primary as alter database create controlfile for standby ... and fill all the gaps with archives.. Should it work ? i am on 10G Rhel 4 linux.. and both machines would have same config
View 12 Replies View RelatedWe have two Windows 2008 VMs with Oracle 11G configured as primary and standby.This configuration has been defined by a partner who is no longer working for us.We have broken the correct application of the redo log on the standby when we have not correctly restored some snapshots on those two VMs.I would like to create a new Oracle server that will become the new standby. For that, I need too :
- Display the full dataguard configuration to reproduce it on the new server
- Stop (delete ?) the configuration on the primary server.
We also have the current problem that RMAN refuses to delete old archivelog since they have not been applied to the standby.
Here we have a dataguard environment with db1 as primary and db2 as physical standby database. We configured dataguard in 10g environments and we are not using grid control. What are the steps for configuring rman for incremental backups in this environment?
We want to schedule the backups to be taken in standby db, (that is applicable in case of switchover too). In the case of switchover to db2 what all do we need to do in rman manually to resume backups in db1?
why RMAN is unable to create physical standby database ?

Dataguard and RMAN.
Got Active DataGuard on a primary database, quite nicely sending its archive logs to its secondary. I can quite happily use the Broker and switchover between them.
Now if I take RMAN backups of the primary database, if I have to failover to the secondary, I'm gonna loose all those backups.
Well, I can restore the whole database to the backup, cos I can restore the control file, from the backuip and therefore I can restore the whole db.
But if I want to restore to a tablespace, I wont be able to , cos the db_unique_names names are different, and the DB ID's will be different.
Same goes if I use a recovery catalog....
so how do I failover/switchover without loosing my previous rman backups ??

I have Oracle database on Oracle 10g R2 with physical as well as logical standby database.
1) Is is necessary to take Physical standby database backup?
2) If 1) yes then Which RMAN backup is preferred?with catalog or default?How to take backup as different location?
3)how to Restore that backup?How to ensure backup is valid?
I got missed the archivelog from primary DB.now its got deleted. But now it is stored in Tape_backup. i don't know about tape backup. how to access and restore the archive_log from tape backup. My tape setup is Legato..ultrium.

We are planning to move BLOB images in our DB to BFILE to reduce the time and size of backup.
So when we have a physical dataguard setup, can we configure data guard to copy the OS level BFILE's to the DR site?

recovery catalog: 10g
I am trying to find if there is a way to know how much data has been written on tape on a 'in progress' rman backup. rman session is also connected with recovery catalog.
is there a way to find-out how much data is transferred per rman channel onto tape? what is backup speed we are getting?

provide any work arounds to proceed further in creating the standby database.
understanding rman scn based Backup Algorithm .. In SCN based backup do rman generate backup from archivelogs ???
View 1 Replies View RelatedI have 2 seperate rman backup one backup is of only datafile ,spfile and controlfile which i am able to restore and recover without any problem say bkp1 taken at 10 am
other set of backup is of only archive log files of same day but later time than datafile backup say bkp2 taken at 8pm...if i restore and recover bkp1 and try to restore bkp2 it gives error datafile exist (possibly due to fact both backup have control file)
if i just restore bkp1 and try to restore bkp2 so that i can do one recover at time
it gives error datafile permission issue (possibly due to fact both backup have control file)
I want to restore database upto 8pm time how can i use both bkp1 and bkp2 to do it(restore datafiles and apply all archive logs on it)
We have physical data guard configured version (10.2.0.4). We are in need to upgrade primary & standby database to 11G R2. Can we perform rolling upgrade.

We are doing RMAN Duplicate set until time to refresh daily our test database for our developers and it taking long time to finish. We noticed on the restore log that RMAN was using a day old old backup pieces to refresh the test database and don't immediately use the latest backup pieces instead.
For additional details here's the rman duplicate command we are using which we run daily(mon-sat) at 4am once daily full backup on production completed.
RMAN Duplicate commands:
run
{
set until time "to_date(to_char(sysdate,'Mon DD YYYY') || ' 04:00:00', 'Mon DD YYYY HH24:MI:SS')";
allocate auxiliary channel ch1 type disk;
duplicate target database to testdb;
}
exit
Is there a way on how to let RMAN use the latest backup pieces instead?
