Active Dataguard Database
Jul 17, 2013I've got a physical standby database and I'm now licensed for Active DataGuard. I would like to automate the ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION command to be executed right after the STARTUP command so that whenever the database is started by our DBSTART script, it activates READ ONLY W/APPLY immediately after start without manual intervention. This is probably simple, but I figured I'd ask before starting to pore through documentation.....!

Sep 14, 2012I have to make this script . It should be something like this :
starting of lsnrctl.......
startup mount;
alter database open read only;

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

Jul 25, 2012We are using oracle as database in our application. For high availability we have a cluster of multiple nodes and the data is replicated using oracle streams. All the nodes in the cluster are active. We do not have any concept of stand-by.
Now we are planning to use oracle RMAN for backup and recovery. RMAN user's guide doesn't recommend any strategies for such deployments. It mainly focuses on primary/stand-by deployments.

Sep 7, 2012I migrated an AQ solution which sends messages between three instances from a development environment to an UAT environment and my propogation from one instance to another is not working as per development.

All the messages are been stored in the queue table and are propogated through only when the instance is restarted.

Which makes sense to me as my understanding of this is that the log is written, send to the standby, applied, then applied on the primary, yes?
So my questions are:
Why is there a lower entry on the primary (234) marked as opening, when it's closing 235, and writing 236, what does LNS mean?
Why is the second archive on the standby saying "CONNECTED 0" and do RFS, & MPR0 mean?
My init files say this:
Primary:
log_archive_dest_1='LOCATION=/u01/archive/prod/arch'
log_archive_dest_2='SERVICE=prod_stby LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=prod_stby'

View 4 Replies View RelatedSQL Script Validation For Use In Dataguard Environment?
Feb 21, 2013We have a 10g environment with DataGuard running for reporting purposes. Our application team is getting ready to upgrade their application and it requires that several SQL Scripts be run to perform the primary database updates. A couple of them are over 1 MB in length. My concern is that these scripts will break DataGuard. I am not a DBA by any stretch, but I seem to remember there are certain limitations with DataGuard.
I have reached back to the team and asked them to have the Vendor confirm these scripts are validated for a DataGuard environment and I have also reached out to the System DBAs for review. I am wondering if there is an utiility available that can check the SQL to confirm if there are any DDL or DML statements that will not work in DataGuard. Likewise, we are going to run these scripts in a non-production DataGuard enabled environment first, but I want to have some level of confidence, that this will be a success.
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 "?

Process To Refresh Schema In DataGuard Enabled Environment
Feb 21, 2013We have a non-production Oracle 10g Cluster running on Linux, with DataGuard (logical standby). From time to time, we need to refresh the schema on primary, but to do so as always caused problems with the logical standby. Our DBAs can never get it to complete successfully. They have tried a bunch of different methods (even provided from Oracle), but it does not work. e have a bunch of skip statements on the
Everytime, we need to refresh the schema, we have to build the entire database (primary and logical standby) from production RMAN backup. As you can imagine this is a very time consuming ordeal. There has got to be a way this process can be completed in a timely manner.
I was thinking of the following....
1) shut down dataguard, log shipping
2) lock user, kill sessions, drop user from primary
3) lock user, kill sessions, drop user from logical standby
4) run impdb on production export file on primary
5) run impdb on production export file on logical standby
6) re-enable dataguard, log shipping
7) confirm logs being applied, databases in sync
We are only replicating the one schema to the logical standby. I am not clear on how redo logs would be applied to the logical standby. There are hundreds of them @ 100 mb each, so I would think if we do this independently, I could somehow sync primary and logical standby after the imports complete.
DataGuard - Archive Log Apply Gap In Physical Standby Database
Nov 23, 20101) The Primary Database is UP. The Physical Stand By Database is DOWN. The Current Archive Log Sequence is 99 in Primary.
We have to apply Archive Log from 51 to 99 to the Standby Database. But Unfortunately, there is no backup of those Archivelogs and the ArchiveLogs from 51 to 98 have got deleted at Primary end.
Now how will you apply these Archive Logs from Primary Database to Physical Standby Database?
Note : The Physical StandBy Database is DOWN.
