Creation of ASM instance.

hi all,
can any one help me out in this regard??
i have a DB in 10gR1 in normal file system. i want to convert this to ASM instance.
Is that first i need to create disk groups followed by adding the asm parameters in init.ora file and then bringing it up or what else the sequence????
can any one give the clear link for creating the disk groups and creation of an asm instance along the asm related init.ora parameters????
I am glad to have your help in this regard...

Please look into Oracle Metalink Document I.D. Note:270065.1 (Use Automatic SGA Management).

ASM Instance Creation

Hi,
I need to just create a new ASM instance on solaris without RAC,can anyone share docs of what are the pre-reuquiite and the details of creation of ASM Instance.
Regards,
Hussain

The ASM OS prereqs are the same as the DB prereqs - e.g kernel parameters, OS packages.
Really difficult to give advice if you won't say what version of the OS, what version of the database, what storage etc.
Some basic docs here :-

Error at ASM instance creation - PRKS-1009

Hello all,
I am in the process of creating a 2 Node RAC database, on VMWare.
OS - RHEL 4 Oracle 10g
I have successfully installed the cluster. After this i was in the process of installing Oracle 10g Binaries.. which installed almost fine, until the time when i had to setup ASM storage options in the DBCA.
Unfortunately, my bad luck the computer rebooted after an automatic (windows update) *Remember i am using RHEL on VMWare server).
I had to unintall the binaries using the Oracle GUI... after that i removed all the files from db_1 folder.
I re-initiated the process of installing the db binaries, until the time i came to the asm option, there i got a prompt asking me to re-create the asm instance, which for which i clicked ok... here.. i got an error.
PRKS-1009 Failed to start ASM Instance "+ASM2" on node "rac2".
[CRS-1028: Dependency analysis failed because of.
[CRS-0233: Resource 'ora.rac2.ASM2.asm' has placement error.
There is one more issue i have, i am unable to use crs_stat command, each time it throws an error saying crs_stat command not found!!
Please guide...

Hello all,
I have managed to solve this problem.
The asm instances were running in the background even after uninstalling the binaries.
I removed the asm instances.
before that i stopped the asm instances.
/crs_stat -t
Stop instance name
crs_stop <output from crs_stat> asm 1
crs_stop <output from crs_stat> asm 2
srvctl remove asm -n rac1 -i +ASM1 -f
srvctl remove asm -n rac2 -i +ASM1 -f
then re-create the asm instance
Thanks!!

RAC ASM instance creation

Can we configure ASM instance on all nodes in RAC at the same time?

790066 wrote:
Thanks for your reply.
Do we have centralized ASM instance for all nodes?
If yes does it should be created on shared device or something else???Normally database will reside in SHARED STORAGE and ASM & RBDMS instances willbe in stand alone systems..
ASM diskgorup will be sharable to all the instances... not the instance can be sharable
Hope you understood.
Thanks

Database creation with ASM using dbca

hi all,
i found the steps to create the database using ASM diskgroup.
but i received errors when configuring the FRA(flash recovery area), DBF(normal), +ARCH(archival dest),
i tried atleast 2 to 3 times from scratch but found the same error....................
ORA: 19624
ORA: 19870
here are the steps can somebody correct these steps..................
Create Virtual Disks from VM Ware software when server is down.
Choose Edit Virtual Machine Settings.
Click on Add button
Press Next and Highlight Hard Disk, then click Next
Check ‘Create a New Virtual Disk’
Choose SCSI as type
Select Size as 2 GB
Name the virtual disk as ‘ASMDBF1.vmdk’
Create additional disks as:
ASMDBF1.vmdk for DBF files
ASMDBF2.vmdk Failover group
ASMFRA.vmdk Flash Back Recovery Area
ASMREDO.vmdk Redo Log Area
ASMARCH.vmdk Archived Logs
•     Start up the server OraWorld1
•     Go to Disk Management and you will be prompted with a screen which should display all five disks with a check mark. Accept defaults and Click next.
•     On second script all five will be unchecked, click Next
•     Press Finish to complete and you should see all 5 disks as Type Basic Unallocated. For each of the disk perform:
1.     Right click, New Partition, Extended Partition and Finish
2.     Right click, New Logical drive, Do not assign drive letter nor partition it.
3.     From command prompt type Diskpart and enter Automount enable.
4.     From command prompt, configure basic CRS services as
5.     C:\oracle\product\10.2.0\db_1>localconfig add
6.     C:\oracle\product\10.2.0\db_1>localconfig add
7.     Step 1: creating new OCR repository

•     Launch DBCA and choose Configure Storage Management.
•     Select Create New group, choose stamp disks which will show you all of your five disks. Configure ASM links to all these disks as:
1.     ORCLDISKASMDBF1 \Device\Harddisk1\Partition1
2.     ORCLDISKASMDBF2 \Device\Harddisk2\Partition1
3.     ORCLDISKASMFRA \Device\Harddisk3\Partition1
4.     ORCLDISKASMREDO \Device\Harddisk4\Partition1
5.     ORCLDISKASMARCH \Device\Harddisk5\Partition1
Now make Change Disk Discovery Path as Null and you should see all disks.
Now create Disk groups as :
ARCH \\.\ORCLDISKASMARCH External 1GB
REDO \\.\ORCLDISKASMREDO External 1GB
FRA \\.\ORCLDISKASMFRA External 2GB
DBF (MAIN GROUP WITH 2 SUB-GROUPS) Must create as Normal Redundancy
DBFP \\.\ORCLDISKASMDBF1 External 2GB
DBFS \\.\ORCLDISKASMDBF2 External 2GB
You now have a running ASM instance on the server.
•     Checking ASM instance
You can always use DBCA to check settings of ASM.
Alternatively, go to command prompt:
Set ORACLE_SID=+ASM
Sqlplus /nolog
Connect sys/password as sysdba
Show sga (80MB)
Total System Global Area 83886080 bytes
Fixed Size 1247420 bytes
Variable Size 57472836 bytes
ASM Cache 25165824 bytes
SQL>desc You can then check C:\oracle\product\10.2.0\db_1\database for these files. You can also view v$parameter for all possible values for ASM instance.
+asm.asm_diskgroups='DATA1','ARCH','REDO','FRA','DBF'#Manual Mount
*.asm_diskgroups='DATA1','ARCH','REDO','FRA','DBF'
*.asm_diskstring=''
*.background_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\bdump'
*.core_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\cdump'
*.instance_type='asm'
*.large_pool_size=12M
*.remote_login_passwordfile='SHARED'
*.user_dump_dest='C:\oracle\product\10.2.0\admin\+ASM\udump'
You can change some of the values like large pool and even db cache size. You can also manually create the disk group as:
Create diskgroup DBF NORMAL redundancy
Failgroup flgrp1 disk ‘\\.\ORCLDISKDATA0’, ‘\\.\ORCLDISKDATA1’
Failgroup flgrp2 disk ‘\\.\ORCLDISKDATA2’, ‘\\.\ORCLDISKDATA3’;
Check Candidate disks:
select group_number, disk_number, mount_status, header_status, state, path from v$asm_disk;
Other useful queries:
Select group_number, name, total_mb, free_mb, state, type
From v$asm_diskgroup;
Select group_number, disk_number, mount_status, header_status, state, path, failgroup
From v$asm_disk;
You can use sql commands to perform most of the ASM tasks, however EM console can also be used here

*•     Enable archiving at +ARCH*
*•     Choose Auto SGA as 55% of memory*
*•     Leave else default and complete DB creation.*
*•     Launch NetConfig and define Listener with default settings.* here i received the errors,.................
Database ORCL2 is created with the following attributes:
NAME: ORCL2
SPFILE: +ARCH/ORCL2/spfileORCL2.ora
URL: http://oraworld1:1158/em

Strange, those messages are RMAN backup errors -- are you trying to backup the database?
Or...if you selected "create starter database" it may be that dbca is not finding the backup files from the "demo" database.

Hi,
I believe your OCR is corrupted....so restore the OCR from most recent backup (before error ).
Using crs_* commands on resources with the prefix ora.* (resources provided by Oracle) remains unsupported.
After restore OCR... remove ASM with "srvctl" command:

ASM instance's block size

Hello.
I have an Oracle 10.2 database running on Linux. Its block size is 8KB. I created ASM instance using DBCA. I see its block size is 4KB, but I didn't specify it anywhere while creation.
Why is that?
Thx.
A.

As for databases 'later' is not possible. I'm not sure what happens when you choose another blocksize at creation time. ASM blocksize is only for metadata,it's not related to the actual database data (having the database blocksize) stored in ASM diskgroups.

Trying to create ASM instance, thinks one already exists?

I've got a problem with creating the ASM instance. Basically, I've reinstalled (v11.1.0.6) clusterware, and two database software installs (one for asm, one for db) due to a san swap. Now, I believe that there is still a hangover to the original installation. When creating the ASM instance through DBCA on Windows, I get the following:
DBCA could not startup the ASM instance configured on this node. To proceed with ASM diskgroup management you need the ASM instance to be up and running. Do you want to recreate the ASM instance on this node?
Yes
Enter password
DBCA will now create and start the ASM instance. After the ASM instance is started, you can create disk groups to be used as storage for your database.
OK
ASM Instance Creation...
Encountered file error when copying listeners from home=D:\oracle\product\11.1.0\asm_2
OK
The operation will be stopped. Re-run DBCA after successfully running NetCA.
I have a listener running (listener_rac), I have a similar problem with netca as it says I already have a listener called listener, which I do not, however, I have created listener_rac instead.
I feel trhat the problem is that ASM1 (for node 1) or ASM2 (for node 2) already exists. However, I can not find either of these. I can create an ASM instance in single node mode, however, this creates an instance +ASM, which does not conflict.
How do I find the non-existent instance, and remove it? (not in registry or services)
Alternatively, any other ideas as to what is happening?
Thank you for your time.

I have a listener running (listener_rac), I have a similar problem with netca as it says I already have a listener called listener, which I do not, however, I have created listener_rac insteadDBCA created your listener... you can check on listener status
srvctl status nodeapps -n node01
Listener is running on node: node01
srvctl status nodeapps -n node02
Listener is running on node: node02
if not start, start it by
Usage: srvctl start listener -n <node_name> [-l <lsnr_name_list>]
srvctl start listener -n node01
by the way, you cam use "netca" delete/recreate (listener_rac)
After that, point to ASM:
I feel trhat the problem is that ASM1 (for node 1) or ASM2 (for node 2) already exists. However, I can not find either of these. What did you see?
crs_stat
srvctl status asm -n node01
srvctl status asm -n node02
if you see asm on node01/node2... you can start them if thet offline
srvctl start asm -n node01
srvctl start asm -n node02
and then.. use "DBCA" to help create ASM diskgroups.
I can create an ASM instance in single node mode, however, this creates an instance +ASM, which does not conflict.that can conflict.. don't start it (+ASM)
How do I find the non-existent instance, and remove it? (not in registry or services)
Alternatively, any other ideas as to what is happening?use "crs_stat" command
http://download.oracle.com/docs/cd/B28359_01/rac.111/b28255/crsref.htm#CWADD6025

Can there be multiple ASM instances on single node?

Hi,
Can there be multiple ASM instances on single node?
This one says No : http://www.freelists.org/archives/oracle-l/02-2008/msg00317.html
And This one says Yes : http://www.databasejournal.com/features/oracle/article.php/3571371
Thanks in advance.
Thanks,
Harsha

...that document doesnt say you cannot have multiple ASM instances on a node. It says "...ASM, +you only need one ASM+ instance for that computer, to manage the two database instances that use ASM."
The fact that you only need one - and I cannot think of a good reason to have more than one - does not preclude the fact that you do seem to be able to have multiple ASM instances on a single node, each looking after its own set of disks and diskgroups.
Again - I cannot think of a good reason to do so though!

Upgrade ASM instance database 10g to 11g

Hi,
In my environment, I have ASM instance database 10.2.0.3 running on solaris 10 (64-bit), I need to upgrade to ASM instance 11.1.0.6 database. please guide me an overview of steps...
thanks in advance

Thanks for the response,
Sorry, In my environment I know database (10.2.0.3) is mounted in ASM diskgroups, now i have a concern
1) If database is mounted in ASM diskgroups, could it be a database instance or it has to be only ASM instance connected to the database?
2) As in my upgrade from ASM instance (10.2.0.3) to ASM instance (11.1.0.6), do we need to upgrade asm instance as well as database? i mean to invoke DBUA twice for upgrading ASM instance then for upgrading database as well?
Sorry for some silly questions...please make me clear...

Multiple ASM instances using single cluster install - Is it possible??

Hi,
I have 2 node RAC cluster installed on Linux. All the storage is on EMC. I need to setup another environment using HP storage on the same hosts. Is it possible to created second ASM instance using the same cluster install?? I wanted to have clear separation b/w EMC and HP environments and that's wondering if it's feasible to do that.
Haven't tried it yet to see if it complains.
Thx
Anitha

Anitha,
The data migration won't happen (at least not aggressively) until you do step 2 in your list where you remove the EMC disks. That removal operation will take a long time as Oracle will have to move the data before it can complete the operation. If you want to be sure, I'd recommend creating a new disk group with one of your new disks, put a small tablespace in it, create some data in it, then add a disk to that new group and remove the original disk. Then you'll have some confidence in the procedure and verify that it works without risking your production data. After you test, you can drop the disk group and use the disks for their intended purposes.
To answer your question, yes, that's the process exactly as I suggested it above. Should work fine--but will probably take a while to do the remove, so be prepared to leave that running for quite a while (i.e. don't expect to close the terminal and go home right after running the remove).

ASM instances on 2 node Oracle RAC 10g r2 on Red Hat 4 u1

Hi all
I'm experiencing a problem in configuring diskgroups under +ASM instances on a two node Oracle RAC.
I followed the official guide and also official documents from metalink site, but i'm stuck with the visibility of asm disks.
I created fake disks on nfs with Netapp certified storage binding them to block device with the usual trick "losetup /dev/loopX /nfs/disk1 " ,
run "oracleasm createdisk DISKX /dev/loopX" on one node and
"oracleasm scandisks" on the other one.
With "oracleasm listdisks" i can see the disks at OS level in both nodes , but , when i try to create and mount diskgroup in the ASM instances , on the instance on which i create the diskgroup all is well, but the other one doesn't see the disks at all, and diskgroup mount fails with :
ERROR: no PST quorum in group 1: required 2, found 0
Tue Sep 20 16:22:32 2005
NOTE: cache dismounting group 1/0x6F88595E (DG1)
NOTE: dbwr not being msg'd to dismount
ERROR: diskgroup DG1 was not mounted
any help would be appreciated
thanks a lot.
Antonello

I'm having this same problem. Did you ever find a solution?
