Oracle Rac with Recovery

Hello, i´m configuring oracle Rac, but this time with a recovery Database

Ex :

server1

server2

recovery catalog database (its in the same oracle rac)

 

Here´s what im doing :

install Ralus

Copy Beotab, edit it in rac1 :

put noderac1

pút recovery catalog database1

 

in rac 2 :

put noderac2

put recovery catalog database2

 

configure the Agent with ./AgentConfig and configure it to use the Ts Name, username, password of the Recovery Catalog database.

I can see the RAC in the Bkp exec console and Bkp it, but, when i put the recovery database in the 2 agent configuration, it´s taking TOO long to start the backup. Is it normal ? Never done one installation with recovery database.

 

Thank you !

Hi

 

Q

Well, i saw the logs and it´s say its working. The job logs in Rman say it´s working.

 

But in my Example, the database is about 550 GB, and the backup is doing only 1.6 GB.

 

Ans:

To verify this why it is only backing up 1.6 GB what happen if you do DBA intiated job using Rman from any one of the nodes and check if it backup 550 gb or 1.6gb

 RUN {
 ALLOCATE CHANNEL ch0 TYPE 'SBT_TAPE';
 BACKUP DATABASE PLUS ARCHIVELOG;
 RELEASE CHANNEL ch0;
 }

 

Please use the above script to run DBA intiated job

 

Moreover ,Please let me know the results of Isolation when you have done that

3 Finally to Isolate the issue please try following

From the second node, using the sqlplus connect to the recovery database and check how much time it takes to connect & see how much time it takes ,if it is taking long time ,it is not a backupexec issue then

 

And finally to answer this question of yours

Q The questions is : with a big database, Backup Exec take a long time to check ? For example, in SQL, it does a physical_check by default.

Ans :

No as like SQL it would not be doing any check so there is something which we need to check.

 

Hope that helps

Thanks

Hi As you are doing or configuring oracle rac with backup exec for first time please check below link just to be sure everything you have setup is correct http://www.symantec.com/docs/HOWTO12569 http://www.symantec.com/docs/HOWTO12577 it´s taking TOO long to start the backup. Is it normal ? Until your backup is running successfully it should not be an issue. Also if you are keen to know why if it is taking long time only one one node and other node it is working fine you can use below link to debug the backup on both the node and compare the debug log too see were is the issue. http://www.symantec.com/docs/TECH67247 Thanks

Thx, i will take a look at the debug note.

About the config, it´s not the first time with Oracle Rac, only with using recovery catalog.

Hi

 

Few thing need to be cleared here

 

1 Is recovery catalog really required in your enviorment

2 If yes then as per best practisces it will be good to have it on both the nodes instead of keeping it on one node

3 Finally to Isolate the issue please try following

From the second node, using the sqlplus connect to the recovery database and check how much time it takes to connect & see how much time it takes ,if it is taking long time ,it is not a backupexec issue then

Hi,

Just to understand better, is your recovery catalog database a rac or normal single node database?

In BEOratab you should only add the oracle rac node that you want to backup, try removing the recovery catalog database entry from the BEoratab file, unless recovery catalog database is also a rac configuration and you plan to backup recovery catalog database like your primary oracle rac database.

Is AgentConfig on all oracle rac nodes configured by providing the recovery catalog database?

Thanks,

Hi

 

Backup_Exec :

Yes, it´s required because the DBA team wants it, so it´s not my call.

Will try to isolate it

Sameer Kapadia :

Yes , my Recovery Catalog database is a Rac, that´s why its added in the beoratab, because without it, the Backup Fail.

Yes, both nodes are configured with the same settings.

It´s just taking longer to start, maybe because of some verification ? I´m not an "oracle guy".

The questions is : with a big database, Backup Exec take a long time to check ? For example, in SQL, it does a physical_check by default.

Hi Thanks and once you isolate and see the vxbsa logs you will come to know difference between working and not working. Regards.
