As part of the duplicating operation, RMAN automates the following steps:
Creates a control file for the duplicate database
Restores the target datafiles to the duplicate database and performs incomplete recovery by using all available incremental backups and archived redo logs
Shuts down and starts the auxiliary instance (refer to "Task 4: Start the Auxiliary Instance" for issues relating to client-side versus server-side initialization parameter files)
Opens the duplicate database with the RESETLOGS option after incomplete recovery to create the online redo logs (except when running DUPLICATE ... FOR STANDBY, in which case RMAN does not open the database) when duplicating for standby database it does not create online redo logs. Duplicating a standby database does not creates online redo logs.
how should I add the online and standby redo logs. If I transfer the redo logs from primary to standby, it always encountered the the following error

If flashback is enable in physical standby database 1. If we failover at 11AM can I flash back NEW primary database to 6 AM ? 2. if I convert physically standby database to snapshot standby database at 11AM , Can I flashback snapshot standby database to 6 AM and do some works on it (DML operations) then converting the snapshot standby database into physical standby database ?

Here we have a data guard environment with db1(db_unique_name) as primary and db2(db_unique_name) as physical standby database. Also we configured one schema on a third machine as catalog database using following steps. The steps executed in catalog database(appsdb):

recovery catalog created
Added tns entries of catalog database in primary and standby. Then from primary database we tried to register to catalog database. It is showing that it is registering. But every query afterwards in rman is throwing the error. Below are the steps and error:

I was using physical standby but my primary database had had some HW issue.So I had activated standby database to handle production.During 3 months, standby database was our live database and our old primary was unavailable.Now HW issue on primary has been fixed.And I want to set again my old configuration : means set primary and standby db.
I'm trying this :
1) check the SCN on old primary
2) Rman incremantal backup from scn
3) on primary db : catalog
4) on primary db : recover database noredo
If my standby database is read only mode,does it can app the archive logs which come from primary database?

View 1 Replies View RelatedI have configured data Guard on oracle 11gR2. It is working fine. The only issue i am facing is that when i am stopping the database on the primary server, it is taking a long long time to down the database.
Is it normal?
Furthermore, regarding backup i used veritas Netbackup to perform hotbackup. Can i still used the same principle.
I am going to change some parameters on primary database (db cache, java pool etc.). I am not sure, if the changes are automaticallly propagated to standby or if I have to make the changes manually on stanby site too? I couldn't find clear answer in documentation. how parameter changes work in dg physical configuration?

1) How to find archive log gap from Primary Database site?
2) Do I need the DB_UNIQUE_NAME when setting the LOG_ARCHIVE_DEST_2 ? What is the purpose of DB_UNIQUE_NAME in LOG_ARCHIVE_DEST parameter?
3) If archivelog gap happens standby db goes out of sync with the primary database. What does out of sync actually mean?
4) Primary DB knows where to transport redo data based on the location mentioned in LOG_ARCHIVE_DEST_n of Primary DB. Am I correct in my understanding?
(Oracle 11gR1 OEL 5)Is there any possibility to convert snapshot database (standby) directly to Primary. Instead of manual switchover I want to do this
I have checked that snapshot creates a guaranteed restoration point which reverts back changes in Standby.
I have a Sap Primry Database and also a standby db that was working perfectly.. We migrated the primary db from windows 2003 to windows 2008 and brought the primary db up.. I had to create a controlfile and do a system copy and had to reset the logs on the Primary.. All came up and when i checked the standby it was receiving the logs but after a month. i see that it was not applying the logs as I think because of the sequence number .. it stopped.
I did the ffg as per the attachement...My logs have been shipped across but not applied, But What worrries me is the log sequence number on my Primary

I want to know if there is any reflection on the standby database states when it's primary is down or not reachable? I want to use this information from standby node to determine if I can programmatically execute (dgmgrl) failover operation or not? This is considering that the broker configuration has no fast-start failover and no observer enabled/configured.
View 4 Replies View RelatedI have a requirement to change the instance parameter of the primary database and standby in the data guard. Any procedure to do the same. I have to do it directly on production and there is no test set up so I cannot experiment . The procedure I am thinking of is as below.
1. Stop the standby
2. backup the primary
3. Change the parameter and restart to make it effective
4. Start the primary
5. Go to stand by
6. Change the parameter and mount the database.
7. Check if both are in sync and apply logs if not.
I new to data guard concept.
I am using oracle 10g with data guard configured , I have primary ( A ) and standby database ( B ) .But because of some unavoidable conditions the primary database ( A ) got shutdown and was not starting , We shifted the standby database ( B ) at new location and changed it to primary with following command ,
startup mount;
alter database recover managed standby database finish;
alter database commit to switchover to physical primary;
shutdown;
startup;
This new primary ( B ) was open for end users for 2 days during which old primary ( A ) was shutdown .
I took the backup of ( B ) and restored it on A AND shutdown the B . Now A is acting as Primary database. Server B is shutdown . I want to change server B to standby database with A running as Primary .Is it possible ?
I am using Oracle RAC 11.2.0.3 as primary database, we are going to start using Oracle data guard. So I am designing my infrastructure and planing to use Oracle 11.2.0.3 Single instance as my physical stand by database.
My question is it feasible to have my standby database as single instance while the primary is RAC? is it feasible to build my Oracle single instance standby database from the RMAN backup of the RAC primary database? Is there any restrictions (or any points to be taken into consideration) since my primary database is RAC while the physical standby is Oracle single instance?
in the below link
[URL].......
it was mentioned that primary can be RAC or single and same for standby, but my question is it feasible to have primary as RAC while standby as single instance? or it should be like each others?
The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters (RAC) database. Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle RAC database.
i have Oracle 10g data guard set up on windows environment.....i need to know the what are the right steps to perform failover in case the primary database gets fail.
View 4 Replies View RelatedWhat is difference when you issue a create controlfile with "standby" keyword on the primary database
ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/path/db_stby.ctl';
vs. creating a control using
ALTER DATABASE BACKUP CONTROLFILE to '/path/db_control.ctl';
what does ORACLE put into the standby control that is "extra"? ie. what is the difference between a standby control file and a normal control file?
How can find the number of standby databases configured for primary database from os level
View 9 Replies View RelatedI have dataguard configuration operating in maximum availability mode with a local standby db (A - lgwr sync not using real time apply) and a remote standby db (B - lgwr async). I then simualted a crash of my primary database with batch jobs running. Since the stby db A is in lgwr sync option ,all the commited data in the current online redo log has been transmitted to stby A and is present in its stby redo log (Group 2).How do I apply this stby redo log to the remote stby db.
Tried the following methods.
1.ftp the stby redo log to the remote db and tried to regiter it, got an error that it is not completely archived.
2.issued the recover standby database command and supplied the stby redo log when it asked for the sequence in the stby redo, got an error saying there is corruption in a block(tried this option multiple times ended up with the same result.)
We have 2 node (n1 nad n2 ) RAC and 3rd node (n3) with Dataguard logical database for reporting ..
1. logical database (n3) not syn with primary (n1,n2)
2. During repair above mentioned problem by mistake my logical(n3) also become primary
3. now how I will again change my n3 to logical
4. I got following error
RE: ORA-16009: remote archive log destination must be a STANDBY database
DB Version- 11.2.0.3
For the maximum protection and maximum availability as well as to enable Real Time Apply we need to setup the standby redo log group. My question is what would be the standby redo log group configuration in case if we setup single instance standby database for 2-Node RAC primary database. Do we require a separate standby redo thread for each primary online redo thread or RFS use the Multiple Standby redo group from the same thread to receive the redo changes from both the node ?
