Data Guard :: Setup/ Archive Destination Configuration
Mar 28, 2011We have a request to configure data guard for databases on the production server. Here is my situation:
We have a backup strategy in place where the backups are being taken on a regular basis. Archive logs are deleted as soon as they are backed up.
My question now is , is there a way of configuring the Data guard in such a way that there would be no change to existing backup strategy (RMAN) and still duplicate the archive logs to another destination and not delete the archive logs by RMAN backup process on that destination while the first destination is deleted.
We will be deleting the logs in the second archive destination using a script which checks if the logs were applied.

Data Guard :: Configuration - Incompatible Media Recovery Is Active
Dec 1, 2011I have created dataguard between two instances hosted in two different servers. I have done switchover from primary to standby & then again standby to primary with DGMGRL utility.
1- When I done switchover to primary & trying to open standby database in readonly mode it was giving below error-
ORA-01154: database busy. Open, close, mount, and dismount not allowed now
Why this error was coming ?
2- As I was not able to open standby database in read only mode, I have executed below command-
alter database recover managed standby database disconnect from session;
which return an error as-
ORA-01153: an incompatible media recovery is active
After this I have executed-
alter database recover managed standby database cancel;
which executed successfully.
& then after standby database open in read only mode.
Why above error was coming ?
3- After this I had tried to check the checkpoint_change# & controlfile_change# from primary database and result shows both number were different.
Why they are not matching ?
Active Data Guard Feature Of 11g To Run Live Reports On Standby
Sep 26, 2012We have 10g physical standby set in our environment and we are migrating to 11g now. We want to use the active data guard feature of 11g to run the live reports on standby rather production. Questions I have is:
1) On our current 10g standby environment, we use db_name=cusms which is exactly matching with the production database name. I don't see we are using database_unique name on our standby. But I have read several blogs where everyone talks about using db_unique name on standby and db_name can be exactly matching with production on 11g. I wanted to know, is db_unique name a new requirement to have on 11g? can I go ahead and not use db_unique name and just have db_name exactly matching with production? What are the implications of doing so? The reason we want to stick to this is in-case of failover we want the database name to be the same. But I want to hear your thoughts on this:
2)While building standby, I did noticed few things and want your clarifications:
a.On standby database, should I mount instance using pfile or spfile or it doesn't matter?
b. Lets say if I use either spfile or pfile, can I just have db_unique name in that file and just start the instance in no mount and do the duplicate from rman?
c.As soon as my duplicate target database for standby from active database got finished, I usually exit the rman session and go to sqlplus and shutdown the standby instance. (Is this ok to do)
d.Then I start the standby instance with startup (mount and open the database) this should open the standby database in read only mode. Following I issue alter database recover managed standby database using current logfile disconnect to put the database in recovery mode. (any steps missing here)
e.Then go to primary and do few log switches and come back to standby to see if the primary changes moved to secondary or not.
But what I have observed is:
a. When I do the duplicate it runs successful. But during the course of duplicate, primary system generates few archives which are not shipped or applied on standby. When I go to standby to recover the database, it says media recovery needed and ask for archives files. I need to manually move this files from primary to standby to apply. Isn/t this automatically taken care?
b. I also noticed after I can not open the standby database in read only mode after the duplicate command. While trying to open, it says database media recovery needed. What's the best procedure to open the database in read only mode immediately?
c. On my standby init.ora lets say if I use db_unique name, where would my control file be place? Will oracle create controlfile from primary and put it on my standby database and put an update an entry into my pfile or spfile?
Data Guard :: Parameters With Active Duplicate For Physical Standby
Oct 17, 2012We are planning to create physical standby database for 4-node RAC primary to a 4-node RAC standby using Active database duplicate with ASM and OMF
1. while using active database duplicate, do we need to set cluster_database=FALSE in spfile clause and create standby,next change it back to TRUE at standby. Or we don't need to touch it. And also do we need to include instance_number parameter
2. We are using OMF, can we use log_file_name_convert parameter in spfile clause of duplicate. Documentation says log_file_name_convert cannot be used if standby is going to have OMF. Because we have 5 groups for each thread, which are on 5 different disk groups. When standby is created all the logs are created in only one disk group pointed by db_create_online_file_dest_1.
3. To enable force logging at primary do we need to shutdown the database?

based on the above result set , for a particular group ,only that op will be retained which comes out in the query . say for example , we have got 1,2,3,'D' for group 1,2,3
now since we have got the D Operation from the above query , i don't need the other two rows .i.e.
(1,2,3,'I');
(1,2,3,'U');
what is the best way to delete the data we don't want retaining the rows we want ,using a single sql statement . Also , for the result set row 7,7,7,T I first need to delete the group containing T operation, and insert two new rows .i.e. 7,7,7,D and 7,7,7,I .
