Unable to Recover Corrupt Oracle Datafile Block In SysAux

javadeveloper picture javadeveloper · Sep 25, 2009 · Viewed 7.9k times · Source

Oracle 10g on Suse 9.1

I'm looking after an Oracle DB. I have good SQL skills but I'm no DBA, (a diffence in job roles I have difficulty explaining to my non-IT savvy bosses!) I know enough to get Oracle up and running and put in place it's 'automatic' options for backup and optimisation then I leave it well alone. Everything else I know from the university of Google!

I recently discovered that our production DB has not been running it's daily backups. It had started one that then hung and didn't report any problems so it was not noticed right away. (The backup job hung, not the oracle instance.)

I have killed the backup, (it got stuck in stop pending so I had to force it out in the end), and I want to get a new backup schedule running, but at the moment I am getting a corrupt block warning. I've tried using blockrecover to fix it but I get RMAN-06023: no backup or copy of datafile found to restore. Running a crosscheck says files are available.

The corrupt block is in the SYSAUX tablespace datafile. If I take the DB offline can I drop and recreate this datafile or will that corrupt the DB? (I'm way to nervous to take the DB offline at the moment as I don't know if it'll come back up!)

Thanks for your help. Below is the output from my recover attempt...

Check the completion times. You have a file for every day from 13-JAN-09 until the 24-MAR-09. Since then, nada. So what RMAN is telling is that it cannot find any backups of datafile 3 for the last six months.

Don't panic.

How big is your database? Is it feasible to do an export? There may be a simpler solution, but if you can get your data out you have the option to recreate the database.

edit

According to the documentation it is possible to drop the SYSAUX tablespace. Details to follow.

edit 2

Dropping and re-creating SYSAUX tablespace is not for the faint-hearted. I confess that this is the first time I have attempted it. Right now I am stymied by this:

SQL> drop tablespace sysaux including contents and datafiles
  2  /
drop tablespace sysaux including contents and datafiles
*
ERROR at line 1:
ORA-29857: domain indexes and/or secondary objects exist in the tablespace


SQL> drop index xdb.xdb$acl_xidx force;
drop index xdb.xdb$acl_xidx force
*
ERROR at line 1:
ORA-29868: cannot issue DDL on a domain index marked as LOADING


SQL> 

This is a road block. DROP INDEX FORCE is supposed to be the workaround for ORA-29868, so I'm non-plussed to see that message. Anyway, once I get beyond this hill I expect there will be others. It don't think it's a tidy process. But then, to be fair, it's not something we're meant to be doing at all.

So, it's good news that you can do an export, because I very much fear that recreating the database is your best bet. Good luck.

Oh, and once you've sorted this situation out, impress upon your bosses the urgency of hiring a DBA (or getting you properly trained, if that is what you would like).

Finally, this is a very good teaching for you. The first time I had to do a restore I discovered the previous DBA had not enabled ARCHIVELOG mode, and I hadn't checked. My punishment was to visit all the users and inform them they had lost a day's work. The moral is, a backup which has not been tested does not exist.
