Control File to a catalog Database

Hi guys,
I'm kind of new here. So sorry if this has already been answered. (did some searching and nothing showed up)
Environment - Oracle 9i
Ok. Currently we are using RMAN with a control file. And there's a requirement to set up a catalog database. I would like to know if there's a way to migrate the current set up to a catalog database. Final goal is to make sure that the past backups will be available after moving to a catalog database.
thanks!
regds,
Dam

Controlfile backup taken during a backup means you will have past information relevant to current state as of the time of the backup. Going forward with a catalog means you will have a longer (as in closer to forever) record of backups whereas a CF only keeps what it can up to the record keep time. You can always catalog prior backups if you want.

Check the value for the parameter "COMPATIBLE" in the source and standby database instance parameter files.
"COMPATIBLE" should be the same.
See http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i70517
"... ensure the COMPATIBLE initialization parameter is set to the same value on both the primary and standby databases"

Problems creating control file in RMAN duplicate database

There is so much detail involved in this operation that I don't know what might be useful, so I'll start simple. I'm attempting to clone a database on the same host using RMAN "duplicate database". I finally got all the setup done, the OS authentication hurdles hurdled, etc. and entered the command:
duplicate target database to COPYCH2M until time "to_date('March 15 2012 12:00:00', 'Mon DD YYYY HH24:MI:SS')";
The first time I got:
ORA-19504: failed to create file "/u01/app/oracle/oradata/COPYCH2M/control01.ctl"
ORA-27040: file create error, unable to create file
Linux-x86_64 Error: 2: No such file or directory
There was nothing in the Oracle instructions about manually creating the directory, but I did so, thinking that might be the problem. And it created the control files! But then I got the following:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

Sounds straightforward, if frustrating, right? Apparently you can't duplicate a database that's not in the exact same version. But:
1) The backuppiece we got the control file from was from last November.
2) The version of Oracle has not been updated since that time.
How can a file created by this version be incompatible with this version? Where is it even getting 11.1?
Thanks, I'm hoping this is easy but I can post more info if needed.

The database is limited as to what it can create. Since you defined where you wanted the controlfiles to go (pfile/spfile), it's up to you to make sure the directory is valid and exists. :)

As for your controlfiles, make sure the compatible parameter is set the same on both the source and the target unless you are using the default (11.1.0.1 for you, and you aren't)
Keep going, you'll get there. RMAN duplicate is a great feature.
Good luck.

NEED TO RECOVER A DATABASE USING RMAN with CONTROL FILE AND NO RMAN CATALOG, DISK FAILURE..

Hello All,
The disk failure caused our production data on the disk to be resotred with the backup data available and recovered through RMAN with cotrolfile , and no catalog DB is configured.
I had the restored the spfile and control file then recovered the database,
startup nomount;
RESTORE SPFILE FROM ' path ' ;
Shutdown immediate;
startup nomount
Restore controfile from autobackup;
restore database;
[AT POINT , A MESSAGE PROMPTED LIKE " failur of restored command - some targets not found" (thinking may be few archives are not found, i proceeded to incomeplete recovery of DB) ]
recover database;
Finished reocvery .
Now in the Grid control i see that 60 blocks of a particular datafile are corrupted and needs recovery. Do i need to get the data file resotred again and recover it or any simple way to recover this data file
When i perform the block recovery , it says recovery failed and when i run the data file recovery it succeeds. Please provide you inputs to recover the database as it is production BI database and pretty critical to our client.
Thanks for your valuable time in advance.
Regards,
Ran G.

These is a common problem if the object are created due to NOLOGGIN option. If you check most of the object which are facing block corruption is indexes .
Use the below query to check the objects :
It will map each block from v$database_block_corruption to either a segment or if the block is free.

Output is no longer available in the database control file

Hi All
in Oracle 10g (10.2.0.1.0) - on suse Linux 9, OEM (10.2.0.1.0); I'm getting when I try to look at RMAN reports that databases reports are "Job output is no longer available in the database control file." - one one database.
I've searched forum and only found one thread
(25/9/2007 - Re: rman backups )
that doesn't have any conclusion to the problem. Has anyone seen this problem before, and do you know if it means there is a problem with the control file?
Thanks, DW

Looks like Bug 4659734
I totally agree with what you say grylew "If you use rman catalogue you shouldn't get this error"; for me, on a Suse 9 Linux server (10.2.0.1.0 db), the error eventually found was ORA-19921 ;
RMAN-06900: WARNING: unable to generate V$RMAN_STATUS or V$RMAN_OUTPUT row
RMAN-06901: WARNING: disabling update of the V$RMAN_STATUS and V$RMAN_OUTPUT rows
ORACLE error from target database:
ORA-19921: maximum number of 64 rows exceeded
Which turns out to say it is a bug fixable by only 10.2.0.4.0 patch or 11g. So awaiting 10.2.0.4.0 I guess.
It all seems to be error assocaited with control file space; and I'f rather keep my control files healthy thanks.
Besides all this; for me the problem is pretty innocuous; it means OEM mis-reports success of archivelog backups; I can see they're successful in 'job's but not in 'backup reports'.
Thanks all for help, DW

Database restore without temp, undo and control files.

Hi All,
You might found this question silly but I don't know so asking this question here.
I have cold back up of the database. Now, I want create clone of that database, but I have some different paths for the DBFs so I will create new control file after restoring the database.
Now, I know that I don't need control files and tempfiles to be restored. I have 10 undo files in backup but on the new clone database I don't need all 10. I want only 5. So can I do the restoration without undo , temp and control file and later on add undo and temp?? and if yes then tell me that can I add them at mount level??
This is my first restore, Please guide me its very urgent

Therefore, we do a RECOVER with a CANCEL to simulate an Incomplete Recovery.Completely agree with you Hemant. And the links you've provided,i've gone through many times. Excellent description.
I just wanted to know in above(OP's) scenario if he has complete cold backup(includes online redo logs), does he really need open reset logs or any recovery?
Regards!no , if you have cold backup with online redo log files then i don't think so you need to open database in resetlogs.Resetlog is always after incomplete recovery or recovery using backup controlfile or you dont have redo logs.
I am completely agree with you that with given scenario for the cold backup undo tablespace would not be part of recovery and you can
-offline drop undo tablespace file
-create another one undo tablespace and its undo datafile
-point spfile to that newly undo tablespace
I think Aman is saying in the context of restore and recover online database where undo tablespace create a vital role in database recovery, the undo blocks roll back the effects of uncommitted transactions previously applied by the rolling forward phase.

Lost all Control files (Want to Recover)

Hi
I have a database in archive log mode and we take a rman hot backup everyday. We are not using the recovery catalog. I lost all the control files
few days ago. I have a control file to trace and that was generated 20 days ago. This is our test database. I want to recover it. I don't know if we have
done any physical changes or not after the creation of this text file to create a control file. Database is still up and running.
Any help will be appreciated?
Thanks in Advance

If the control is restored from the rman backup lets say it is 3 days old, then how to update the same control file with the current database statistics.

Backing up the RMAN catalog database

Version: 10.2.0.1.0
We have created a database to host our RMAN catalog. This catalog holds backup info plus RMAN stored scripts for 5 production databases . Now, we need to backup this RMAN catalog database.
I am going to use the control file as the catalog (ie. NOCATALOG) for our RMAN catalog database. This should be fine. Right? Any best practices i should follow regarding this?

Sometime back I had the same question.
What I decided was cold backuo and RMAN using the control file. (A Belt-and-suspenders approach)
I also do an export daily after all the other backups are done.
In addition I keep an information on it, location and size of all files, a current PFILE (it does not change much), what patches etc.
Given its tiny footprint it would be easy to rebuild given all this.

RMAN & Control file ...

Hi,
Is any reason to use the control file of a production database as repository for RMAN ? If the disks where the control files are located will be broken RMAN can't be used for a restore & recovery.
Thanks for your answers,
Paul

Are you basically asking whether it is better to use a control file to store RMAN backup information than an RMAN catalog?
The reasons you should use an RMAN catalog are -
o take advantage of the full features of RMAN (database clone for example).
o recover to another server even if there is a total server loss of the original server and database
o not have to potentially restore the control file copies from a filesystem backup to perform a restore
As someone else pointed out the DBID is stored in the catalog and you will need this to restore from complete database loss.
If you're using a third party product (allocating channels to sbt) then I would use an RMAN catalog to store all the backup information and on which tape they are.
You need to consider if you're a case where the RMAN catalog is not required. What type of disaster are you planning for?
Also, if you use the control file be aware of the control_file_record_keep_time

Hi,
Sorry, my mistake, I did not pay attention to the cloning part.
For this error, looks like the database was not cleanly shutdown before copying the files or that preclone was not run successfully. You will have to run preclone again, and shutdown the database normally, then copy the file again.

How to use old archieve logs with a new control file

Environment:
ORACLE_BASE="/export/home/oracle"
ORACLE_HOME="/export/home/oracle/product/8.1.6"
NLS_LANG=".UTF8"
2 partitions:
i) /data1 -- contains important datafiles (OS striping on 3 hard
disks)
ii) /export/home -- contains the oracle program, and SYS/SYSTEM
datafiles
Problem:
-/data1 cannot be read/mount (damaged)
-oracle failed
Action Performed:
-reinstalled OS
-mount /export/home successfully (all oracle system files,
instance init files exist)
-/data1 is an empty partition
-created the oracle user, and its groups
-chown recusively for the $ORACLE_BASE directory
-set all the oracle environment variables
-attempted to start the instance, but failed due to a control
file was
missing
-since control files were set to be mirrored, i copied a control
file somewhere
from /export/home/oracle/oradata/<SID>/control1.ctl to
/data1/oracle/oradata/<SID>/control2.ctl (i.e. have them back to
their original locations)
-the instance failed to start as well, since the datafile set in
the control files couldn't be found
-this forced me to re-create the control file... b4 i re-create
a new control file, i backed up the old one
-once the control file was created, the database can be started,
but, to oracle, all achieve log information are lost (although
the achieve log's physical files r still there)
-i imported the important data from a dump file that was
exported a week ago b4 the system failure
-since we r using the new control file, the redo logs switch
contains no achieve log information that the old control file
has, so running "recover database" doesn't do anything
Purpose:
since the dump file is a week old, i'd like to get the data
after my last export and b4 the system failure. the database was
run in arhieve log mode, how can i recover those data with the
new control file
Question:
-how can we create a new control file that can drive the old
achieve logs?
-can we convert the achieve log data (.dbf format) into text
format?
-can we still use the old control files to start the database?
-what's a suggested solution if we'd like to re-construct the
database up to the moment b4 the system failure in another
server?
thx

We are running Oracle 9i on Windows XP. We are upgrading soon to Oracle 11g on a newer platform, but need to get our development environment working first.
We lost a system that was running our development database without having a database export. The C drive was placed into a new system as the D drive.
I have loaded Oracle 9i on the C drive, but I have been unable to determine how to point it to the existing data files on the D drive. My search skills may be the limiting factor here...
We cannot simply load the drive as C, since the hardware is different.
What are the steps to point the new database software at the data files on the D drive? Or, how do I copy the old data files into the new Oracle Home and have them recognized properly?
Are you stating that you don't know how to use COPY command?
Can you recreate same directory structure on new C drive as exist on old C drive?
Can you then drag & drop copies of the files?

Whwn to create a standby control file?

Hi All ,
I want to setup a standby database for my Production DB.
I have a doubt, can we create a Standby by control file when the Primary database is up and running(read-write) mode. or else it is must to be in mount state only ?
Please advise.
Thanks.

Hello;
I do it like this: (And then copy the STANDBY.ctl to the Standby system and rename)
SQL>startup mount;
SQL>alter database create standby controlfile as 'STANDBY.ctl';
This command will fail is STANDBY.ctl exists.
See step 8 of my cliff notes here:
http://www.visi.com/~mseberg/data_guard_on_oracle_10_step_by_step.html
Or Step 7 if Oracle 11 here:
