3.turn on flashback on both databases.
4.record SCN xxx on physical standby database.
5.convert physical standby to logical standby (using keep identity statement)

On next month i will have plan to delete history data on my Primary database, but i still want to keep them in logical standby as the data warehouse. So, how can i skip delete statement from primary database apply to logical standby.

Data Guard :: Apply Patches On Oracle Database With Logical Standby Database?

Apr 22, 2011

I got a primary database with a logical standby database running Oracle 11g. I got two client applications, one is the production site pointing to the primary one, another one is just a backup site pointing to the logical one.Things will only be written into the primary database every mid night and client applications can only query the database but not add, update nor delete.And now, I want to apply the latest patch on both of my databases. I am also the DNS administrator, I can make the name server pointing to the backup site instead of the production one.I want to firstly apply the patch on the logical one, and then the physical one.

I found some reference which explains how to apply patches by adopting "Rolling Upgrade Method". however, I want to avoid doing any "switch over" mentioned in the reference because I can make use of name server. Can I just apply patches as the following way?

1)Stop SQL apply
2)Apply patches on logical standby database
3)let the name server point to the backup site
4)Apply patches on the primary database
5)Start SQL apply
6)Let the name server point back to the production site

Data Guard :: Windows To Aix (logical)

Oct 18, 2010

I have a Windows 2003 server with Oracle 10.2.03 database residing in one datacentre, with Dataguard configured to a physical standby in a similar location (proven process that works great).

I now have a requirement to transfer and synchronize the same live database to a database in a different country (AIX box), purely for data purposes not failover etc. I can transfer an export of the Database and have this up and running as a logical database of the live on AIX, but is it then possible to configure dataguard on the Windows server to also send updates to this logical database on the AIX system? Thus keeping them in sync with each other?

Data Guard :: Apply Standby Redo Log To Physical Standby Database

May 26, 2013

I 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.)

Data Guard :: Recreating Physical Standby

Jun 4, 2010

I have an issue whereby our standby instance was down for a couple of days and when it came back online we found an archivelog file was missing, so recovery only happened up to a point. It appears that the archivelog was deleted therefore we are unable to continue with this standby. We are now planning to rebuild the standby database. As far as i know all of the steps originally performed need not be performed to complete this task.

1. Shutdown standby
2. Delete all datafiles & redo logs
3. Copy over datafiles to respective directories
4. Copy online logs and archivelogs to standby.
5. Create a control file for standby database
6. Startup mount standby database
7. start redo apply

Data Guard :: How To Delete Archive Log On Standby

Jun 18, 2011

We are planning to setup a data guard (Maximum performance configuration ) between two Oracle 9i databases on two different servers.

The archive logs on the primary servers are deleted via a RMAN job bases on a policy , just wondering how I should delete the archive logs that are shipped to the standby.

Is putting a cron job on the standby to delete archive logs that are say 2 days old the proper approach or is there a built in data guard option that would some how allow archive logs that are no longer needed or are two days old deleted automatically.
