Data Guard :: Apply Standby Redo Log To Physical Standby Database
May 26, 2013I 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 :: Possible To Convert Logical Standby To Physical Standby
Aug 30, 2013My steps for testing as below:
1.create a primary database
2.duplicate a physical standby database;
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)
6.flashback to logical standby to xxx
7.convert logical standby to physical standby
8.using real time apply I got errors: Fast Parallel Media Recovery enabledManaged Standby Recovery starting Real Time ApplyMRP0:

Restoring Standby Database
Sep 27, 2012My standby got corrupted and I need to restore from Primary database. As it is already setup , no need to configure listener and tnsnames.
At Primary site
==========
1. After shutting down the primary database.
2. copying all .dbf and log files. (need to query v$datafile and v$logfile)
3. Copying archive logs. (not sure about this step)
4. Again restart, create control file for standby database.
5. Restart primary database.
Standby
=====
1. After changing the location of control file on standby parameter file (initSTANDBYDB.ora)
2. Startup nomount pfile='/pfile/location'
3. Mount the standby database.
4. Putting database in MRM mode.
Standby Auto Startup On OEL 5
Sep 14, 2012I have to make this script . It should be something like this :

and a second script is to shut down everything correctly during Linux shutdown..I think it would be better to make a new Linux service . make a whole script? Oracle 11.2, Oracle Linux 5
Creating Standby Database In OEM 10g?
Dec 7, 2012DB = Oracle 10.2.0.4
OS = Solaris 10 Sparc
I am trying to create a physical standby database using the add standby database option within OEM 10g. This is something we have done numerous times before on 10g and 11g db's without a single issue, but for some reason, this time after selecting my RMAN backup location and staging area location , I am getting the following error when I click Next:
RMAN Backup Location - The specified RMAN backup is invalid. Could not identify controlfile from the backup
It is the latest backup (using RMAN catalog) from the previous evening and includes datafiles and control file.
Here is the output for List backup:
BS Key Size Device Type Elapsed Time Completion Time

Piece Name: /carebackup/oradata/CARELIVE/carelive/backup/df_CARELIVE_4811_1.bus
[code].....
The only difference between creating a standby for this db and others we have created is that the file system the backups are stored on is on a non-global zone shared via nfs mount.
I know that when I try and share that filesystem with other servers I get the message: share_nfs: Cannot share filesystems in non-global zones If the /backup filesystem is not shared with any other servers would OEM be able to read from that NGZ? The filesystem is available to connect to using ssh from other locations, but not sure how OEM handles this part of the process.

View 4 Replies View RelatedCreating MV Logs In Logical Standby DB?
Dec 10, 2010I am trying to create materialized views based on a few tables in a logical standby database.
The target database (11g R2) where the MVs will be created is a stand-alone database.
The DB where the base tables reside is a logical standby database (11g R2).
The requirement is to do a "FAST REFRESH" of the Materialized Views.
My questions are :
1. Can I create MV logs in the logical standby DB?
2. If the answer to question no. 1 is "Yes", do I need to do anything different or configure the logical standby DB in a specific manner in order to create MV logs. From what I understand, the objects in the logical standby database are in a locked state.

Dataguard Setup Primary And Standby
Dec 2, 2011I have a dataguard setup, a primary and a standby.my instance is testdb.i have set all necessary dataguard parameters and everything seemed to work well initially with logs being moved from primary to secondary and being applied there.but all of a sudden i see that the primary pushes logs to the standby and at the standby end these logs are available but not applied.
when i try to execute the: alter database recover managed standby database cancel; it hangs for a long time and never returns to sql prompt.
i bascially want to stop and restart the MRP process to apply the logs but cannot cancel the managed recover mode.Is it advisable to kill the mrp process at os level using "kill -9 "?

Recovering Standby DB From Incremental Backup
Nov 11, 2010I've got a physical standby (10g) which is missing some archive logs, and thus the managed recovery is stuck. I followed the procedure for taking an incremental backup of the primary from the last SCN in the standby, and then recovering the standby from that backup using rman.
It seemed that everything went according to the instructions, except that the "recover database" of the standby from the backup went much faster than I expected. Afterwards I checked the SCN of the standby (select current_scn from v$database) and it had indeed updated to a number beyond where it was stuck originally. The standby controlfile was restored from a backup of the primary's current controlfile, and the standby restarted. The problem is that when I started up standby recovery again, the standby is still looking for the logs which were missing. I can't figure out why! I've been googling around and digging through the docs, and the only clues I can find suggest that this would happen if the standby controlfile wasn't updated. But I did that.

Rename Database With Physical Standby?
Jul 23, 2010I need to rename an Oracle9i database on windows which has a physical standby database running on a different machine.
I have the steps to rename the primary database but am unsure of it's impact on the physical standby database. It seems like I will have to re-create the physical standby database, since renaming the primary database involves opening the db with "resetlogs". It's a production environment hence can't play with it without knowing the results.
Physical Standby TEMP Tablespaces
Aug 7, 2013I have a Physical Standby database on server#2 which has its UNDO and TEMP tablespaces in a mount point that is a bit small. I discovered yesterday that this mount point was completely filled. This is not an immediate problem, because even though the TEMP and UNDO tablespaces are large, there is almost no usage of them.
I logged into my Primary, and created a new temp tablespace (TEMP2), made it the database default, dropped the TEMP tablespace, and then re-created the TEMP tablespace in a different mount point (with a much higher capacity!). I then made the new TEMP as the database default temp tablespace again. I expected that these changes would be propagated over to the Physical Standby via log application, but they didn't come over.
I have standby_file_management set to AUTO, and there are no unapplied logs. Everything OTHER than the temp tablespaces seems to be in synch.
