Cloning a database on ASM and rawdevices.

Hi list,
I am in the process to "test" a clone procedure in a database which is using ASM and "rawdevices".
Is there any special Note that I can follow to accomplish this process?
How can I copy a raw device from one server to another one?
Any advice will be really appreciated.
Thanks in advance.
Kind regards,
Francisco Mtz.

Hello Martin,
Yes you can clone ASM database from one server to another server. Here is the brief overview of how i was able to do in the same RH Linux 4 and 10g R2
1) source - take a RMAN backup (ASM databases can be backed up using RMAN only
2) target -
a) create a ASM instance on the target
b) let your unix SA create a raw device disk with the same capacity of the source
c) create a new diskgroup that includes this new raw device disk using $ORACLE_HOME/bin/dbca of the target's ASM instance (it will be automatically mounted)
d) Now use RMAN DUPLICATE database option to create a duplicate database (clone) of the source database.

Cloning Oracle database with ASM --

Hello All,
I am new to ASM.
We have recently migrated our 10g database into 11gASM. Now we want to clone the database to a different server. I am completely aware of the cloning a standalone database. But this is something new to me. Cloning a database which is in ASM is new to me. Please help me with the steps.
thank you

Nothing is there to change in the case of ASM. The normal procedure standalone database cloning applies here.
One thing you got to rememer is the DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT. Set the ASM path in both parameters as source.

E Business suite 11i with Database in ASM - Cloning

Hi All,
We are planning to migrate the E Business suite database to ASM and wanted to know the best cloning method to perform the cloning from Production to non production.
Applciation - 11.5.10.2
Database - 10.2.0.4 in ASM
Since i dont see any specific notes in metalink on this, raised an SR with oracle and they told that oracle does not support this but we can use RMAN as few of the customers use RMAN to perform the clonine.
Can you please advice on the best methode to perform this
Our constraints :
We have a constrain in performing the cloning through RMAN, for performing the duplicate database we need to have the sqlplus connection between prod and non prod. We will not be getting this setup due to security policy.
I had referred the "Best Practices for Cloning ASM-managed Databases" white paper

Create 10g Database with ASM on Windows Server 2003 x64

I am running Windows 2003 Server Enterprise x64 on a Dell server and wish to install Oracle 10g 10.2 with ASM.
First, I performed a software only install. Then, I created several raw partitions on each of two SATA2 disks, and created a disk group - DGROUP1 - using two partitions from each disk. So far so good.
Next, I tried to use DBCA to create a general purpose database using ASM, and that is where the problem arose. I can use sqlplus to stop and start the ASM instance, but when I use DBCA to select ASM for storage I am asked for the SYS password for ASM. I enter it and get a message "Passwords cannot be verified because: Io exception: The network adapter could not establish the connection". If I ignore this I can go on to select my DGROUP1, but the installation ultimately fails due to "insufficient privileges".
Can anyone please help?

Hi Martin
Thanks for the reply. I used ASMTOOLG to stamp the disks and then used DBCA and followed the description hereo create the disk group DGROUP1:
http://www.databasejournal.com/features/oracle/article.php/3571371
At one point, DBCA prompted me to run "localconfig add", which I did.
If it is a missing password file that is the problem, is it possible to create one to put things right?

Database migration from non rac and non asm to RAC database with ASM

HI,
i have requirement to import one database ( db1) which running one node with out ASM and with out RAC , now i want to import that database with rman backup to another database ( db2) which running on different server with 3 node RAC and ASM ( disk group +DATA ) , can you please provide me the steps how i can migrate.? ( i have created db2 with dbca with RAC).
regards,
sri

Sri,
This could be done multiple ways. Simplest for you is to use DBCA:

Cloning a 10g Database using DBCA and templates

I have created a template from a 10G database (structure and data) and want to use this template and data to create a clone of the database on another server using the DBCA on the standby server. Where does DBCA ask for the names of the templates of my clone database? It seems to only have templates for its pre-existing databases (wharehouse, general purpose, custom, etc.).

Thanks. I figured this out on my own and seems work fine. My problem is I am connected over a Window network domain and the transfer speed is very slow. I finally had to kill the job and manually move the critical control, init, redo, and data files that DBCA missed. I also had to use the DBCA again to create the EM DBconsole server as well as copy over the, initPROD.ora file as well as the tnsnames.ora, listener.ora and sqlnet.ora files over to the $ORACLE_HOME/Network/Admin directory. SPFILE was create using create spfile command, I had to perform a recover database once in the initial startup of the database clone.
If I do this operation again I will move datafiles and DBCA template components from the server to a USB SCCI Drive connected locally to the source server then connect this remote disk to the target server rather than transfer files over a domain network.
Any other tips that anyone can over on cloning a database using DBCA in 10G please let me know any things to avoid, traps, bugs, best practices would be greatly appreciated.

Upgrading clusterware and RAC database including ASM

Hi All,
I have a 3 node RAC database with ASM running on RHEL4(32bit). current version is 10.2.0.1. I want to upgrade clusterware, database and ASM to 10.2.0.4.
Please let me know the patch number for this upgradation.
At the time of googling i found that 1st we have to upgrade 10.2.0.1 to 10.2.0.3 then we can upgrade it to 10.2.0.4. Is it true?
Thanks

You are absolutely correct. Database should be upgraded at last. I may be wrong regarding upgrading of ASM. but what my thought is saying it should be upgraded or it may upgrade when we will upgrade our database. So please think little bit on it. ASM has its own instance. we are upgrading clusterware and database. why we are not upgrading our ASM. Then what should be the method to upgrade ASM.
Please correct me in i am wrong.

How to configure automatical startup of both ASM and Database

I created a ASM and a database that uses this ASM for file storage management. I also edit the /etc/oratab file as followings:
+ASM:/u01/app/oracle/product/10.2.0/asm:Y
orcl:/u01/app/oracle/product/10.2.0/db_1:Y
However, when I reboot the system, both ASM and database instances cannot be started up automatically.
How can I configure automatical startup of both ASM and Database at system reboot?
Thanks in advance!

try the following
Create file called startdb.sh in $ORACLE_HOME/bin and put following line into startdb.sh and
change the permission of the file with following command.
$vi $ORACLE_HOME/bin/startdb.sh
su - oracle -c 'sh /oracle/product/10.2.0/db_1/bin/dbstart'
Please replace /oracle/product/10.2.0/db_1/ with your ORACLE_HOME
$chmod 777 $ORACLE_HOME/bin/startdb.sh
Open /etc/inittab file and append following two lines in /etc/inittab.
h2:35:once:/etc/init.d/init.cssd start >/dev/null 2>&1 </dev/null
h3:35:wait:/oracle/product/10.2.0/db_1/bin/startdb.sh >/tmp/stdb.out 2>&1
If you have h2,h3 in the inittab file please feel free to change it to h4,h5 or whatever is unique, but it has to be unique name
Please replace /oracle/product/10.2.0/db_1/ with your ORACLE_HOME.
Reboot machine and check out whether both instances are getting started or not.Please check $ORACLE_HOME/startup.log for more information.

ASM and database instance sharing same home. Can i split them?

Hi I am running on 10.2.0.1.0 in a 2 server RAC cluster on linux. ASM and db instance are sharing the same home.
I now need to upgrade my ASM instance and clusterware to 11g, but just want to keep my db at 10g because of some compatability issues ( i will probably still need to upgrade the db to 10.2.0.5.0).
Is there any way i can split my Oracle Home so that i now can upgrade my ASM home and keep my prod DB instance still at 10g?
Thanks again. John

Hi;
Presently we are following RMAN duplicate database cloning from RAC asm to (non RAC)non asm database of size 1TB.
If suppose if our databse is 3TB or More. then is there method that we can minimize the cloning time. If so please let me know.We have 4 Tb RAC+ASM and we also follow same method. I belive there is no faster method, at least we can not find :)

Can't create database using ASM (SOLVED)

Hi all
I'm trying to use ASM for the first time, on Oracle 10.2.0.1 on Solaris x64.
I have installed the ASM instance into /opt/oracle/asm/10.2.0 and created disk groups. I have cssd running OK. I am able to start and stop the ASM instance without problems, and I can select from v$asm_diskgroup to confirm that disks are mounted OK.
I have then installed Oracle EE separately into /opt/oracle/server/10.2.0. I first did a software only install, and now I am trying to create a DB.
The problems come when I try to use this ASM instance to host a new database. I first tried to use DBCA to create a new database, but on database creation I got the following errors:
ORA-00200: control file could not be created
ORA-00202: control file: '+DBLIVE1'
ORA-17502: ksfdcre:4 Failed to create file +DBLIVE1
ORA-15001: diskgroup "DBLIVE1" does not exist or is not mounted
ORA-15055: Message 15055 not found; No message file for product=RDBMS, facility=ORA
ORA-01031: insufficient privileges
I then told DBCA just to create the DB creation scripts, and I tried manually running these with SQL*Plus.
When doing it with SQL*PLus, I initially got the same error as shown above. But then something changed (sorry, not sure what), and now the error I get is:
CREATE DATABASE "NEONREL1"
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-00349: failure obtaining block size for '+DBLIVE1'
ORA-01031: insufficient privileges
I've put some debug info below, showing me succesfully connecting to the ASM instance and then attempting to create the DB using the db creation scripts, showing the error at the end. You can see that the oracle OS user is able to connect fine to ASM, then I swithc ORACLE_SID and ORACLE_HOME to the EE install and try to create the DB, at which point it apparently can't connect to ASM any more.
I've tried the DB creation many times, and in between attempts I completely empty $ORACLE_HOME/admin/<dbname> and delete the files related to the attempted install from $ORACLE_HOME/dbs/ . I've also stopping/starting ASM, rebooting, and I've done the install of ASM and EE a couple of times over in case I made any mistakes in my earlier attempts.
Any help would be much appreciated!

Update: I've worked out the difference between the two sets of errors I get.
The basic error is this:
ORA-00200: control file could not be created
ORA-00202: control file: '+DBLIVE1'
ORA-17502: ksfdcre:4 Failed to create file +DBLIVE1
ORA-15001: diskgroup "DBLIVE1" does not exist or is not mounted
ORA-15055: Message 15055 not found; No message file for product=RDBMS, facility=ORA
ORA-01031: insufficient privileges
However if my init.ora contains the line:
control_files=/opt/oracle/server/10.2.0/dbs/cntrlNEONREL1.dbf
then I instead get the second error:
CREATE DATABASE "NEONREL1"
ERROR at line 1:
ORA-01501: CREATE DATABASE failed
ORA-00349: failure obtaining block size for '+DBLIVE1'
ORA-01031: insufficient privileges
So basically these must be the same error, just in the second case I'm not trying to put the control file on the ASM so it fails at a different point.
But both errors must be because of the same cause, I suppose.

RAC with ASM and shared disks?

Hi all,
Can someone clarify this little point please. If I use ASM as my storage with a RAC database, I have to configure these nodes to shared disks. At least this is what the UG says ...
When you create a disk group for a cluster or add new disks to an existing clustered disk group, you only need to prepare the underlying physical storage on shared disks. The shared disk requirement is the only substantial difference between using ASM in a RAC database compared to using it in a single-instance Oracle database. ASM automatically re-balances the storage load after you add or delete a disk or disk group.
With my 9i databases, I used HCAMP to allow for concurrent VG access among the nodes. My questions are ...
1) How can I share this storage as stated above without using HACMP? My understanding is with 10g I no longer have to use it.
2) Can Oracle's clusterware be used to share storage? I have not seen any indication that it does.
3) Does this mean I still have to use HCAMP with 10g crs to allow shared storage?
Thank you

"...meaning visible to all the participating nodes, which you don't need HACMP..."
This is one step forward, but still not clear. On unix, storage is presented to ASM as raw volumes. As such, how can these volumes be visible on all nodes without using HCAMP (or whatever 3rd party clusterware you are using). Presenting raw volumes on several nodes is something that is not done at OS level without using some clusterware functionality.
I do understand that storage or LUNs can be shared at the SAN fabric level. But then, these LUNs are carved in bug chunks and I would like to be able to allocate storage at much granular level using raw partitions.
So all in all, here are my questions ...
1) On unix platforms, can ASM disks be LUNs, raw volumes, or may be both?
2) If raw volumes, how are these shared (or made visible) without using 3rd party clusterware? Having managed 9i RAC, it was the function of HACMP to make these volumes visible on all nodes, otherwise, we had to imp/exp VGs on all nodes to make them visible.
Thank you

Creating standby database from ASM production database in standard edition

Hi,
I am using oracle 10g release 2 standard edition. I recently created a database instance and wanted to create a standby database instance. After sorting out how to achieve this without managed standby and data guard I finally got it working and the shipped archive logs are applied and working well on the standby database.
Now I am thinking of re-creating my production database and using ASM for storage managment. By doing this can a standby database still be created from a primary database using ASM? I want to be sure I can before I commit to using ASM for the production instance and manually creating a standby database from that instance.
Note: I am using standard edition not enterprise edition.

Hi
For Oracle SE standby, you can visit www.anbultechnologies.co.uk , they have a brilliant product name DRMC which is Automatic disaster recovery solution with automatic failover in case primary goes down due to any reason.
We are using this product for more than 2 years and it works like a dream using Oracle Standard Edition. We have depolyed more databases and Standby solution within the prices of 2 EE edition licenses.
You can give ma try as well.

How to create second database at ASM in 4 node RAC system

Hi Experts,
we use 4 nodes RAC (11.0.1) with 10.2.0. 4 database in red hat5.0
we want to add second database at ASM in RAC system based on manager decision.
how do I add second database in ASM with exist database?
Do I need to created new ASM insatnce?
how to create two new diskgroup? is it under existing ASM instance or new ASM instance?
how to reset ASM properity to support ( or new) ASM instance and two database?
Do I need to configure AMS again after added more space into ASM?
I could not find ducument that add seconf database into ASM in RAC system.
I want add second database by dbca. any experience for add second database in ASM RAC ?
Thanks for help!
JIm

Hi... I'm in the same situation.
I need to add a new second database on a RAC installation based on already available ASM instance.
I'm using 11gR2.
I read your suggested documentation. Then I typed asmca and analyzed my asm configuration:
As you can see I have a DISK GROUP NAME with several FREE space.
!http://img522.yfrog.com/img522/8405/dbca20100203173248.jpg!
If I select Volumes tab the following is my current configuration:
!http://img682.yfrog.com/img682/562/dbca20100203173343.jpg!
Selecting Create button, I can insert some values as you can see:
!http://img403.yfrog.com/img403/9889/dbca20100203173403.jpg!
First question:
Is this the right way to create space for a new database ? Consider that running dbca.. no DISK GROUP NAME is available.
Second question:
When I created my first database on this DISK GROUP NAME no volumes were created. Why now I have to do it ? Is this necessary to really separate datafiles coming from different databases ?
