Hi all,

Code: [Select all] [Show/ hide]

SQL> select banner from v$version;

BANNER
----------------------------------------------------------------
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE    10.2.0.3.0      Production
TNS for Solaris: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production

SQL>

Oracle runs on Sun-OS.

The software tree serves 3 instances.
All are backup up by rman.

Strange thing is: 2 of the databases will backup fine, no problems what so ever. The 3th one has some strange behavior.

The actual backups go fine. But when I type "exit" It will take some 3 quarters of an hour to exit the rman cli.

I noticed that this also happens when the control-file autobackup has finished :

Session example:

Code: [Select all] [Show/ hide]

bash-2.05$ rman target / nocatalog

Recovery Manager: Release 10.2.0.3.0 - Production on Fri May 1 10:55:08 2009

using target database control file instead of recovery catalog

now wait 3 quarters of an hour

After 3 quarters I'm able to type along within the cli:

Code: [Select all] [Show/ hide]

RMAN> exit

now wait 3 quarters of an hour more

Code: [Select all] [Show/ hide]

Recovery Manager complete.
bash-2.05$

I really don't have a clue where to have a look actually.

btw:....tdp is used. The tdp_optfiles are the same for all three instances.

Does anyone have an idea how to go and solve this problem.
Anyone an idea wher to look?

Bets Regards,

Martijn

Hi all,

Just some feedback on this one:
I didn't find a cause, but did find a solution:
I added the following to the backup script sql "alter session set optimizer_mode=RULE";

I do not quite understand why this is an improvement, but ...it is.

If you have any suggestions or pointers why not using the CBO helps in this case, I'm more then happy to learn.

Best Regards

Martijn
