Duplicating controlfile in ASM

Hello all,
I've just created a 10g stand alone database with just one controlfile. I have just one DG but I want to multiplex it using RMAN copy.
Can someone tell me what are the steps to duplicate the controlfile in ASM?
On controlfile will reside in +DG/<DID>/controlfile and other will be in +DG/<DID>/datafile directories in the same DG.
rman copy from to
alter system set control_files='+DG/<DID>/controlfile/ct1.f','+DG/<DID>/datafile/ct2.f' scope=spfile
Thanks

see the oracle docs :
Performing RMAN Recovery: Advanced Scenarios
"RMAN uses the autobackup format and DBID to determine where to hunt for the control file autobackup. If one is found, RMAN restores the control file to all control file locations listed in the CONTROL_FILES initialization parameter.""

Hi,
How we can do multiplexing of control files in ASM.
and How we can find free space on disk groups.

How do I copy a controlfile to ASM

I have a database in which the datafiles are in and ASM instance but two controlfiles are multiplexed to normal ext3 linux filesystems.
How do I copy the controlfile to ASM to multiplex the controlfile there too ? Can I use rman convert to do this ?

if your disk group is data1, then set control_file='data/control01.ctl' in init.ora file
startup nomount your database using init.ora file
RMAN>connect target;
RMAN>restore controlfile from '<your_location>';
RMAN>alter database mount;

How can I add a new controlfile in ASM?

In the ASM,I can't copy any file.How Can I create a new online controlfile? Thanks!

You can use "alter database backup controlfile to trace" command to get the control file contents.
Now you can use create controlfile:
1) If you use resetlogs, use file creation context form for specification of log files.
2) If you use resetlogs, use file reference context.
Why do you want to create a new control file. Is it for multiplexing purpose?

Hope this will help you.

Controlfile on ASM performance question

Seeing Controlfile Enqueue performance spikes, consideration are to move control file to separater diskgroup(need outage) ? or add some disk(from different luns,( i prefer this approach) in the same disk group , seems like slow disk is casing this issue...
2nd question :can snapshot controlfile be placed on ASM storage?

Following points may help:
- Separating the control file to another diskgroup may make things even worse in case that the total number of disks are insufficient in the new disk group.
- Those control file contention issues are usually nothing to do with the storage throughput you have but the number of operations requiring different levels of exclusion on the control files.
- Since multiple copies of controlfiles are updated concurrently a possible, sometimes, problem is that the secondary copy of controlfile is slower than the other. Please check that this is not the issue (different tiers of storage may cause such problems)

Multiplex Controlfiles in ASM

I have been trying to figure out how to multiplex a controlfile that is in an ASM instance. Normally I would simply shutdown the DB, copy an existing controlfile to my desired location, update the pfile or spfile to the desired location and startup the DB. Since my existing controlfile is in ASM though, I can't do the copy part.
I have tried using RMAN to restore a controlfile, but I can't seem to get the syntax right.
I have seen thread Re: How to multiplexing control files in ASM instance??? however I really don't want to issue a RESETLOGS just to be able to multiplex my existing controlfile. In this thread there is another suggestion without having to issue a RESETLOGS, but this does not seem to get this to work for me. Any suggestions? Thanks.

I found the answer I was looking for. If anyone else had this question, the answer is in metalink document id 345180.1

Mutliplexing controlfile on asm - asmcmd cp not working

Attempting to multiplex a controlfile on new database I have setup in 11.1.0.6 on ASM.
Existing control file in +DATA diskgroup in asm
Steps as follows:
alter system set control_files
= '+DATA/abc11g/controlfile/current.260.660240667'
, '+FLASH/abc11g/controlfile/current_controlfile_backup'
scope=spfile;
shutdown database,
copy one of controlfile to new locations in +FLASH using cp command in asmcmd
startup database.
Error message as follows:
ORA-00205: error in identifying control file
I alert file I found:
ORA-00227: corrupt block detected in control file: (block 1, # blocks 1)
ORA-00202: control file: '+FLASH/abc11g/controlfile/current_controlfile_backup'
ORA-205 signalled during: ALTER DATABASE MOUNT...
It appears the cp command in asmcmd does not work correctly, even though the file is physically there - or am I doing something else wrong?

Just out of curiosity, what's the exact reason you want to multiplex control files? You already have redundancy at ASM and/or disk subsystem level, and you can have RMAN to keep an up-to-date autobackup of controlfile for you in +FLASH diskgroup.

Duplicating controlfile autobackup

hello
i can use following command in RMAN for duplicating backup set

thanks

Autobackup of controlfiles are never multiplexed.

Duplicate standby asm controlfile parameter

Hi
I want to create a standby database by using duplicate standby command.
Both primary and standby databases are on asm.
How should I set controlfile parameter in standby database spfile before initiating duplicate for standby clause ?
Primary:
SQL> show parameter control
NAME TYPE VALUE
control_files string +DATA/orcl/controlfile/current.260.769439087Should I set the same controlfile parameter for standby spfile or should I just set "+DATA" ?
I tried setting just "+DATA", however during duplicate, the instance couldnt create a controlfile in ASM.

http://docs.oracle.com/cd/E11882_01/server.112/e25608/scenarios.htm#SBYDB4897 says:
>
If the primary database is configured to use OMF, then Oracle recommends that the standby database be configured to use OMF, too. To do this, set the DB_CREATE_FILE_DEST and DB_CREATE_ONLINE_LOG_DEST_n initialization parameters to appropriate values. Maintenance and future role transitions are simplified if the same disk group names are used for both the primary and standby databases.
>
So try to not set CONTROL_FILES parameter and set only DB_CREATE_FILE_DEST parameter:
DB_CREATE_FILE_DEST='+DATA';

Creating two controlfiles in an auxiliary init.ora file

How can two controlfiles be created in an auxiliary init.ora file ?

for asm you can connect as asmcmd (change ORACLE_SID/HOME first) and copy controlfile (don'r forget, shutdown, modified init.ora, and startup with init.ora):
ASMCMD> cp <controlfile at disk> <controlfile at asm>
i.e.:
ASMCMD> cp '/tmp/control01.ctl' '+DATA/controlfile/control01.ctl';

How many control file should be created in ASM for ORACLE 4 nodes RAC

We have a oracle 10G(10.2.0.4) database with 4 nodes locates ASM in redhat linux5.
The vendor created this RAC system with database.
I saw below infornation as
SQL> select name from GV_$CONTROLFILE;
NAME
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
+FLSDISK1/sale/controlfile/current.256.690290159
It seems that each node with one control file.
I got a feedback that vender claimed SAN is very reliable.
I am new person for database at ASM for RAC.
Could you make a explain for this condition? Do I need to add ( mirror) another 2 control file into ASM?
The Oracle recommands that at least 2 contril files( best 3 files) in different place. This is true for signle instance.
How about RAC that database locates in ASM?
Please help me!!
Jim

You are fine using the standard three controlfiles in ASM, four is fine too, but it does not need to be tied to the number of instances as all the instances in a RAC database use the same controlfile (and its copies). ASM knows the controlfile type and will stripe each one in 128k pieces across as many volumes as it can. I much prefer to have my controlfiles in ASM, it prevents accidental deletion and generally makes DBA life easier.
Cheers!

Multiplexing controlfiles

Hi All,
I have recently completed migration of Database from OCFS to ASM. I have started the database with one controlfile. Now i want to create another 2 copied of controlfiles. As far as i know in normal filesystem's case the steps to accomplish this will be
1. Bringdown database
2. Create copied of controlfiles using cp command.
3. Change control_files parameter in initfile.
4. bringup the database using initfile.
But incase of ASM i am not sure how i can copy control files, i tries using RMAN but i am getting errors that the second controlfile is not in sync with the first/original one. I do really appreciate any help you can provide regarding this.
Thanks,
Aditya.

1. Shutdown the database and start the instance:
SQL> shutdown normal
SQL> startup nomount
2. Use RMAN to duplicate the controlfile:
$ rman nocatalog
RMAN>connect target
RMAN>restore controlfile to '<DISKGROUP_NAME>' from '<OLD_PATH>';
3. On the ASM instance, identify the name of the controlfile:
Using ASMCMD:
$ asmcmd
ASMCMD> cd <DISKGROUP_NAME>
ASMCMD> find -t controlfile . *
alter system set control_files='newone', old one' scope=spfile;
shutdown immediate
startup.

What are the steps applying incremental backups to standby database 11g

Hi All,
I have built 11g none ASM standby database from ASM RAC Database. Now I want to apply incremental backup to the standby database from primary but not sure how to do it. I tried following and I had an error “ORA-01103: database name 'ins-prim' in control file is not 'ins-sec'”
1- I have configured standby database with RMAN backup.
2- After finishing installation, I took a incremental backup from primary server(ins-prim) and moved incremental backup and control file to the standby (ins-sec) database
3- I stared standby database nomount mode
4- restore controlfile from “incremental backup location in standby database”
5- alter database mount; and got this error
“ORA-01103: database name 'ins-prim' in control file is not 'ins-sec'”
What are the steps applying incremental backups to standby database with 11g?
Thank you

I build the database from backup and changed from ASM to none ASM and changed location of data files and logfiles. I think this changes makes the standby database as logical one.
You can a have a physical standby with different locations for everything (redo/controlfiles/datafiles), ASM and no ASM etc. I have a such a configuration in production (10gR2)
I build the database from backup
Are you sure you have a standby ? Ins-sec receives the archivelog files from the primary ? How did you proceed to build this database ? I suspect you don't have a standby at all ! If you have duplicated the database ins-sec and ins-pri are independent databases and you won't be able to apply an incremental backup (your script was not correct but it is another story)

Need suggestion regarding drop RAC database of 11g

Hi All,
I have 11gR2 RAC environment setup. Database required recovery and I have no backup, based on support engineer guidance I restore the database using some hidden parameters though its a corrupted db so I need to rebuild. For rebuild purpose I took expdp of entire database and then drop it. I had drop through "dbca" , db was open and I run "dbca" and select drop database option, at one time it showing me warning/error ORA-01586:database must be mounted EXCLUSIVE and not open for this operation but after that drop was run perfectly.
but when I check the ASM disk status , it still show as it is , I mean no change in their free_space column, I also verified through asmcmd command and all the Datafiles are still there.
I want to cleanup asm disk which are still fillup with dbfs and I thought that would be cleared by dropping database but no my assumption was wrong.
can any one suggest me what to do if I want to make free space in asm disk which was allocated for dbf files?
Thanks in advance.

RMAN clone; Avoid backup image

Oracle 10.2.0.5
When cloning databases with RMAN on ASM, it creates a backup image before restoring the backup to a clone. Whenever I clone a database, I need double amount of storage to do it.
Is there way to clone a database in ASM and avoid the additional backup image?
I appreciate the help.
Thank you

Hi Philippe,
I really appreciate your post, doing things that seem impossible to be possible. (such as to duplicate (online) a database in 10g without restore). :)
I decided to complement your post doing duplicate using ASM.
I did not make step by step, but for any Senior DBA can understand.
P.S: For All:
Be very careful to do this using ASM because you can damage or remove your target database if the parameters(init<instance_name>.ora) are not configured correctly.
I created/used a different diskgroup from that used by the target database, for precaution and safety.
