Trying to recover database after disk failure [message #505631]

Hi,

I am a Oracle newbie.

I have a situation in that our server died , multiple disk failure, the database was open at the time.

We have managed to recover the data from the disk and have put it on another disk.

We have got a new server with oracle 9 running.

A blank database has been created.

I have copied the control files and redo files onto the new server and left the datafiles , (.dbf,.ora) on a seperate external disk F drive (this is because the original database resided on F drive)

I can mount the database , however when I try to open it I get the following

ORACLE instance started.

Total System Global Area 135338868 bytes
Fixed Size 453492 bytes
Variable Size 109051904 bytes
Database Buffers 25165824 bytes
Redo Buffers 667648 bytes
Database mounted.
ORA-01122: database file 1 failed verification check
ORA-01110: data file 1: 'F:\ORACLE\ORADATA\LCMPRO\SYSTEM01.DBF'
ORA-01207: file is more recent than controlfile - old controlfile

Any help would be appreciated

Daryl

What have you from the previous database?
* spfile (if used) or init.ora
* control files
* data files
* log files
* archived log files?

Which backup(s) have you (of each above category)? And which kind (RMAN, cp...)?

Regards
Michel

Hi Michael,

Unfortunately we have no back of any kind

init.ora
all the control files
all the datafiles
all the redo.lof files
no archived log files (there was no folder recovered)

Thanks for your response.

Is this the list of the files you have from before the failure? Or is this the list of the files you lost?
Are you in archivelog or noarchivelog mode?

Michel

Why have you this message "file is more recent than controlfile - old controlfile"?
Did you take an old control file or is this the current one?
What exactly failed?
What was on what has failed?

How did you recover them?
Actually I am unable to understand the picture you have.
Describe step by step what happened and what you did.

We had a company recover the files for us.

The server hard disks failed .

Sent the disks to a company to recover the data, received the recovered data.

Constructed a new server and installed oracle 9 , created a new blank database structure.This a inventory tracking database.

Ensured the new database worked. (new database same structure).

Deleted all files from the oradata folder and copied the control and redo files that were recovered .

All the other database related files reside on another disk labeled F , as they were originally on a F drive.

Tried to mount the database and had a problem with 1 of the control files of blocksize mismatch ,did some googling and found that if i deleted the control file (03) that was causing the problem and copy one of the other ones (02) and rename it . This worked and I was able to mount the database.

I can mount the database , however when I try to open it I get the following

ORACLE instance started.

Total System Global Area 135338868 bytes
Fixed Size 453492 bytes
Variable Size 109051904 bytes
Database Buffers 25165824 bytes

Database mounted.

Remove all what you did, drop the new database and service.

Copy the files you got from the restore (that is from your previous post, control files, data files and redo log files). Have you the old init.ora or spfile? If yes copy it to %ORACLE_HOME%\database, if not recreate the init.ora from either previous alert.log if you have it or from memory.

Recreate the Oracle service using ORADIM.

Startup the database and post what you have.

Copy files to where ? What about the fact the original files where on the F drive ?

Recreate the Oracle service using ORADIM.

Is this a SQl command ?
Sorry about the questions as this is my first adventure in Oracle

1) Yes drop ALL what you did.
2) Copy to their original location (if you can't then tell me but you said you already did it, so redo it)
3)

C:\>oradim
ORADIM: <command> [options].  Refer to manual.
Enter one of the following command:
Create an instance by specifying the following options:
     -NEW -SID sid | -SRVC srvc | -ASMSID sid | -ASMSRVC srvc [-SYSPWD pass]
 [-STARTMODE auto|manual] [-SRVCSTART system|demand] [-PFILE file | -SPFILE]
 [-SHUTMODE normal|immediate|abort] [-TIMEOUT secs] [-RUNAS osusr/ospass]
Edit an instance by specifying the following options:
     -EDIT -SID sid | -ASMSID sid [-SYSPWD pass]
 [-STARTMODE auto|manual] [-SRVCSTART system|demand] [-PFILE file | -SPFILE]
 [-SHUTMODE normal|immediate|abort] [-SHUTTYPE srvc|inst] [-RUNAS osusr/ospass]
Delete instances by specifying the following options:
     -DELETE -SID sid | -ASMSID sid | -SRVC srvc | -ASMSRVC srvc
Startup services and instance by specifying the following options:
     -STARTUP -SID sid | -ASMSID sid [-SYSPWD pass]
 [-STARTTYPE srvc|inst|srvc,inst] [-PFILE filename | -SPFILE]
Shutdown service and instance by specifying the following options:
     -SHUTDOWN -SID sid | -ASMSID sid [-SYSPWD pass]
 [-SHUTTYPE srvc|inst|srvc,inst] [-SHUTMODE normal|immediate|abort]
 Query for help by specifying the following parameters: -? | -h | -help

So "oradim -new <sid> ..."

Regards
Michel

This will give you the parameters you have to put in your init.ora file if you didn't recover it.

Is this is the alert.log you get after executing the steps I mentioned or is this the original one?

ORA-00202: controlfile: 'F:\oracle\oradata\lcmpro\control03.ctl'

the above is the error on the screen after trying to open the database using enterprise manager console in standalone mode and using the original init.ora file

So maybe control file control03.dbf is corrupted, remove it from the init.ora list and retry.

Please copy and paste ALL what you do otherwise I can't know what you really have and so can't help efficiently.

As I said, I can't see what you do and get.
I see you use OEM, you should not, you should use SQL*Plus.
You are too inexperienced for me to be able to help you remotely and seeing nothing of what happens.

You can't be lazy when you do a recovery.
You are unable to tell me what the tool executed so you are unable to know in which status it is.
Drop all again, use CMD box and SQL*Plus and copy and paste all what you do and get.
