Data Guard :: Check If Database Encrypted Or Not On Primary / Standby?
Jul 25, 2013We have a primary and a standby (Physical Dataguard) site.

Data Guard :: FAL Request Rejected Error And Log Shipping Not Working?
Apr 7, 2011I have a 10gR2 standby database.Normally when logs are created in primary they automatically get shipped to standby but sometimes I get FAL request rejected or connection lost contact error and the logs are not automatically shipped .

Data Guard :: Setting Up Physical Standby On Server With Different Structure
Jun 28, 2012I am having a few issues trying to set up a physical standby database.
The primary database has a different naming structure than the standby and they are at different sites.
Physical is /var/hpsrp/ctrorp03/oradata/u0x/<DB_NAME>/<DB_UNIQUE_NAME> and standby is /var/hpsrp/drforp03/oradata/u0x/<DB_NAME>/<DB_UNIQUE_NAME>.
I have set db_file_name_convert to '<PRIMARY PATH>', '<STANDBY PATH>' times the number of paths as pairs. I have created a blank database for standby and having taken a full backup of primary with control file and standby control file.
Now I hit the issues:
The DB incarnation numbers are different. When I try and do a normal restore e.g. set dbid, restore controlfile; mount; it fails as it is trying to find files in the primary structure and not standby structure. When I try renaming via set newname or auxname it can't find files to restore I guess due to the incarnation id's. If I set the incarnation id and try to restore backup it fails as the incarnation id's don't match.
I have tried looking through various forums and the documentation but can't find a solution, probably can't see the wood for the trees though as there is so much.

Data Guard :: Change Server B To Standby Database With A Running As Primary
Oct 4, 2010I new to data guard concept.
I am using oracle 10g with data guard configured , I have primary ( A ) and standby database ( B ) .But because of some unavoidable conditions the primary database ( A ) got shutdown and was not starting , We shifted the standby database ( B ) at new location and changed it to primary with following command ,
startup mount;
alter database recover managed standby database finish;
alter database commit to switchover to physical primary;
shutdown;
startup;
This new primary ( B ) was open for end users for 2 days during which old primary ( A ) was shutdown .
I took the backup of ( B ) and restored it on A AND shutdown the B . Now A is acting as Primary database. Server B is shutdown . I want to change server B to standby database with A running as Primary .Is it possible ?

Data Guard :: Data Change In Metro Cluster
Oct 21, 2012Our organization has recently decided to go for storage metro cluster solution for disaster recovery. In a Data guard environment, we normally calculate how much archive log is generating and based on that value we calculate the required bandwidth.
For storage metro cluster, we need to find how much block is changing in our primary database, and the same rate of change would apply on DR cluster. Now, i need to give the assumption how much changing is happening in my system. How to calculate the change.
SQL & PL/SQL :: Check Every Table For Data?
Oct 30, 2012I'm working on a feature that needs to check every table for data. At the moment I am roundtripping every time and running the query like this:
SELECT 1 FROM dual WHERE EXISTS(SELECT 'x' FROM table_name)
Is there a better way that allows me to get the result for all tables in one trip? I've tried a correlated subquery like this:
SELECT table_name, (SELECT 1 FROM dual WHERE EXISTS(SELECT 'x' FROM table_name) FROM all_tables
but I think that doesn't work because Oracle looks for a table called table_name rather than the value from the outer query.
