Data Guard :: Archivelog Source Directory In Standby Database

Jul 15, 2013

I created a standby database yesterday and everything is working correctly.  I need to make some tweaks, however, and one of those is the directory that the standby database expects the archivelogs to be.

I found that the archivelogs were being shipped to $ORACLE_HOME/dbs and named arch*.arc.  Interestingly a log switch ships the archivelog minus the "arch" at the front and all archivelogs now do not have that format. I moved the archivelogs to the correct location and renamed them.  I have been able to set the correct location using standby_archive_dest and can see that the archivelogs are shipped to there.

Also, v$archived_log shows the correct path and filename. The problem I have is that when I come to apply the archivelogs it still seems to think that they should be in $ORACLE_HOME/dbs and named with "arch" at the front.  what parameter I need to change to tell oracle the correct path and filename to use when applying the archivelogs?

Data Guard :: How To Delete Archivelog In Standby Database When Applied Successfully

Aug 20, 2008

How to make the automatic deletion of all the archivelogs when it is applied successfully on the standby database? We have 1 primary database and 1 standby database using oracle physical dataguard.

In the primary database, we have daily backup job so that the applied archivelogs are deleted automatically, no problem

But in the standby database ( physical standby) I have to go there and delete manually because I don't issue backup on this database. Is there any solution for this problem.

Data Guard :: Configure Archivelog Deletion Policy To Applied On Standby

Nov 16, 2012

I have a DR setup with the following configuration

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY

I dont want to backup the STDBY DB but I want the ARC files to be removed when applied so my flash area does not fill up. Is there some command(rman or not) that can fire off this policy?

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.)

Streams :: Apply Archivelog / Generated Before Reset-log Of Source Database In Destination Database

Feb 9, 2013

Database Version - 10.2.0.4.0
OS - Red Hat Linux

We have configured oracle one way stream between two databases. Source database is capturing the changes (No downstream configured). Configuration was working fine but destination database was lagging behind very much i.e about 15 days behind the source database. We are ok with this but the problem is now that , as per client request we have restored previous backup and open the database with resetlog option in source database. After resetlog , archivelog sequence has been changed and stream is not working.

Can I apply the previous archivelog (before resetlog archivelogs ) in destination database anyway.Source database is a production database.

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 :: Backups On Physical Standby Database (RAC)?

Nov 23, 2011

I have set up a single instance standbys for rac databases. Now, I need to offload the backups from the primary on to the standbys.

1. cancel managed recovery

2. connect to target(standby) and catalog and backup the standby

3. put standby in managed recovery mode.

I think following these steps, I can restore primary(?). Now, My question is, how can I use these standby backups to clone/refresh databases? I tried it by connecting to target(primary), catalog and auxiliary but rman is using the primary backups instead of standby's to refresh the auxiliary database.
