Incompatible control file

I attempted to upgrade 10.2.0.1 to 11.2 but things went wrong. So, I am trying to start the source database but I get the following error: ORA-00201 control file version 11.2.0.0.0 incompatible with ORACLE version 10.2.0.1.0. Is there any way I can make this control file compatible with my source DB? I am no DB admin but I think I may have a backupset but I have no idea what's in it and how to restore controlfile from it.

Is it possible to recreate controlfile without restoring database? I was reading [managing control files|http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006293] from 10.2 database administrator's guide and it looks like to me it is possible. As I mentioned, I am no dba admin so please bear with me.
Yes, it is possible to recreate the control file. If you still have 11.2 software installed on target system and you have the init.ora file created as part of your failed upgrade attempt, the easiest way to do it is this:
1. load the 11.2 environment (set ORACLE_HOME, ORACLE_SID, etc.) and mount the database in 11.2 (that is, version that is compatible with control file version)
STARTUP MOUNT PFILE='/path/to/init.ora.for.11.2'2. backup the control file to trace:
ALTER DATABASE BACKUP CONTROLFILE TO TRACE AS '/path/to/ctlfile_recreate.sql' NORESETLOGS;3. shutdown 11.2 instance
SHUTDOWN IMMEDIATE4. open the generated file and review it. If you see any statements you think are not needed, comment them out (like those related to standby log files.)
5. change your environment to 10.2 and run the script in SQL*Plus - it contains all commands necessary to start the instance, recreate the control file and other files, recover the database and open it.
Make sure you backup the whole database before doing this (you actually should've done that before upgrade attempt - if you did, you could simply restore from backup and be done with it already...)

Control file version 10.2.0.1.0 incompatible with ORACLE version 10.2.0.0.

hi;
I'm totally new to the oracle databases field...am trying to startup the database using the parameter file init.ora by using the command
startup pfile='/u01/app/oracle/product/10.2.0/db_1/dbs/init.ora'
But its giving me the following error:
ORA-00201: control file version 10.2.0.1.0 incompatible with ORACLE version
10.2.0.0.0
ORA-00202: control file:
'/u01/app/oracle/product/10.2.0/db_1/dbs/control01.ctl'
Can anyone help me with this error?
Thanks!

startup pfile='/u01/app/oracle/product/10.2.0/db_1/dbs/init.ora'You are most likely using the wrong init.ora file. Get a list of files at /u01/app/oracle/product/10.2.0/db_1/dbs/
For the database ORACLE_SID that you are attempting to startup, there would be an initSID.ora or spfileSID.ora
e.g. if the ORACLE_SID is PROD, the file would be initPROD.ora or spfilePROD.ora
The spfileSID.ora is a binary file and should not be accessed by a text-editor.

Hi,
I have upgraded the database from 9.2.0.4 to 10.2.0.4 and for some time compatible parameter remained 9.2.0.0.
Recently i have changed compatible parameter to 10.2.0.4.Now I could open the database with pfile but when I am trying to open database with spfile then I am getting following error:--

Yes,everything is set to 10g only with spfile I am getting this error.
When i am starting it with pfile it is opening and running good the onle thing I can not enable alter system set db_file_recovery_dest_size=5G scope=both bcoz spfile is not being used .I started using pfile and created spfile from pfile and then bounce the database startup then I am getting above error.

Getting a ORA-00201: control file version 10.2.0.1.0 incompatible with 10.0

I have just shut down and restarted a production database. It will not open.. It wasn't recovered, upgraded or anything, it was shutdown and an attempt was made to restart it.
ORA-00201: control file version 10.2.0.1.0 incompatible with ORACLE version
10.2.0.0.0
There does not seem to be an spfile.
what could be going wrong here?

It sounds like someone made a change to the COMPATIBLE parameter and saved it to SPFILE (or even updated the init.ora file) only to cause a problem on restart but you say there was no SPFILE. Have you tried changing the COMPATIBLE parameter back to what it was on the previous start? Check the alert log for the history of changes and previous values.

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"

Oracle binary and control files

Hi All,
I want know whether the oracle binary and control files are they related in anyway.
I have my physical files on a SAN storage and my oracle binary files on a local disk.
In case if I delete my oracle binaries and restore it from a backup, will I be able to start my database without any issues.
Since all my oracle datafiles,controlfiles and redofiles are located in SAN storage.

Oracle binaries and control files are related in some way because Oracle version is recorded in control files:
oerr ora 201
00201, 00000, "control file version %s incompatible with ORACLE version %s"
// *Cause: The control file was created by incompatible software.
// *Action: Either restart with a compatible software release or use
// CREATE CONTROLFILE to create a new control file that is
// compatible with this release.When restoring Oracle binaries on UNIX you should take care about setuid bits on oracle executable to avoid local connection issues by non oracle Unix accounts.

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: ===========================================================
RMAN-03002: failure of Duplicate Db command at 05/21/2012 15:59:25

ORA-00202: control file: '/u01/app/oracle/oradata/COPYCH2M/control01.ctl'
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.

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.

Problems creating control file (duplicated database)

Hello,
We're duplicated database but some datafiles weren't added on controlfile creation script, so I need to recreate controlfiles again with missed data files.
I launched controlfile creation script but I get the following error:

In case of Control File Failure, Create Control File cmd how get scn?

The following lines i picked from the
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:5033895918209
======================================================
1. We can use the 'alter database rename ' at mount stage to rename any datafile. Or is it not possible to rename the system datafile like this? Why?
2. What happens to the SCN information in the controlfile when a controlfile is recreated? How will the database sync the SCN with that of the datafiles?
If I issue a 'backup controlfile to <file>' at 8 am and then restore that controlfile binary backup at 10 am and try to open the database, it will give me a control file old error. I understand that it is because the SCN is not in sync. But if I issue a 'backup controlfile to trace' at 8 am and use that script to recreate a new controlfile at 10 am, why doesn't I get the error? Where does it get the SCN information then?
So what is the use of taking a binary copy of the controlfile. Looks like having a 'backup controlfile to trace' script is better than a binary backup. Do you agree? Why/whynot?
Followup August 16, 2002 - 2pm US/Eastern:
1) you could but I just always did it with the create controlfile statement.
When moving system -- I do it that way
When moving ANY OTHER tablespace -- i just offline it, move the files, rename the files online it.
2) it just happens.
The control file you create will read the files to figure out what is up.
I agree, I've never used a binary controlfile backup myself.
=========================================================
My Question- In the Point2 above "Where does it get the SCN information and how control file do SCN Sync with data files?
"

1. The CREATE CONTROLFILE reads SCNs from the DataFiles. If the
database was last shutdown, all the datafiles are "non-fuzzy" and have the same
SCN (as of the shutdown checkpoint), If the database or some of the files are from
are hot backup, you cannot open the database because the SCN of some files is
older (lower) than others -- that is why a RECOVER (DATABASE or DATAFILE) is
required.
See http://web.singnet.com.sg/~hkchital/Incomplete_Recovery_with_BackupControlfile.doc
2. I'm not sure I agree with Tom Kyte's response
"I agree, I've never used a binary controlfile backup myself. "
to the question
"So what is the use of taking a binary copy of the controlfile. Looks like having a 'backup controlfile to trace' script is better than a binary backup. Do you agree? Why/whynot?"
If you have lost your database (storage/filesystem failure) and all your datafiles are lost,
you cannot simply do a CREATE CONTROLFILE from a Trace -- because the
CREATE CONTROLFILE has to read and verify all the datafiles specified in the
CREATE statement. If you have an RMAN Repository, you can use that to restore
your database files but otherwise, the RMAN information about backups and backupsets
are in the binary controlfile.
That is why it is important to take binary controlfile backups either manually or
using RMAN or using CONFIGURE CONTROLFILE AUTOBACKUP ON.

Creation of control file

Hi friends,
I want to do homogeneous system copy.
I want to know the steps in homogeneous copy, and how to create control file from source system for target system.
And after that what activity is required .
thanks
Regards
Manoj

hi
while doing homogeneous copy sap will do some functinalaties through one sql file I think it will take control file backup and recreate it.
if u want to do manually
issue command
sql>alter database backup controlfile to trace;
look for trace file in udump dir from that file u can recreate controlfile or rename database.
before doing take complete cold backup of source.
start process with sap inst
it will do certain tasks ref in manual
let me know if u knoe some more inputs

Creation of control file in Oracle 10g

Hi,
I had taken the backup of control file(backup control file to trace) and edited it to change the new location of the datafile.But when i try to create the Control file(Startup nomount,@cntrl.sql) it fails with the following error
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-01276: Cannot add file
/oracle/DBS/redolog/DBS/controlfile/o1_mf_2s4ho2n8_.ctl. File has an Oracle
Managed Files file name.
how can i recreate it?

HI,
what are you actually trying to do...
relocation of datafile or control file.
if you want to relocation of data file then go through below link

How can i validate the data in the control file?

Consider that the SQLLoader reads the Input data File from the path and it loads the data into the tables based up on the descrition specified in the control File.
First, the table to be filled is created:
create table sql_loader_1 ( load_time date, field_1 Numeric, field_2 varchar2(10)
Sample Control File :
load_1.ctl
load data
infile 'load_1.dat' "str '\r\n'"
insert into table sql_loader_1
load_time sysdate,
field_2 position( 1:10),
field_1 position(11:20)
Note that the positions 11 through 20 are loaded into field_1 and positions 1 through 10 into field_2. The field load_time is filled with the current time (sysdate) of the load.
Here's the data. The name of the file (load_1.dat) had been specified with the infile statement in the control file.
load_1.dat
0123456789abcdefghij
foo bar
here comes a very long line
and the next is
short
Here i want to validate the field_1 (Numeric Datatype) since the data file contains the character value (i.e)abcdefghij
