How to configure ASM of 11gR2 RAC on Solaris 10
Hi all,
I have the first time to install the RAC on Solaris 10. I have stuck on the ASM disk group step in the Grid Infrastructure.
Our Configuration
2 Sun Server in Solaris 10 with same configure (which we are not using shared drive)
250GB Local Hard Disk
1100 GB Raw Disk (which at SAN)
3GB x 3 Raw Disk (which at SAN) for voting disk
When I install Grid Infrastructure, I select first option: Install and Confgure Grid in Cluster (I can't remember the exact name) and also select the Typical Installation. The previous steps are successful before the ASM Disk Group. At ASM Disk Group, no disk are display for selection.
So, how to fix the missing disk in this ASM Disk Group creation?
Please help!

I would break the 1100G into 11@100G devices and use EXTERNAL redundancy (RAID on the SAN side). You will get much better performance. (Configured/managed a 250TB 3node cluster on Sun 6900s however my LUNs were 1.5TB in size)

Sunny YipAgain using a single 1.1TB device will not get you better performance and should you need to add additional devices, they too will need to be 1.1TB. Sometimes smaller is better.
Make sure you use a partition that starts at cylinder 1 or 2
Make sure you set the correct permissions (660) and ownership (gridowner:oinstall) on those devices and make sure the oracle user is a member of that group.

Configure ASM Instance in RAC cluster - problem
Linux RH4 with Oracle 11.1.0.6
I previously had ASM working in a RAC environment, but have uninstalled on all 3 nodes following Oracle guidelines.
When I attempt to re-configure ASM it states that an ASM instance is located in nodes 2 and 3. Previous ASM software has been removed, and there are no entries in the /etc/oratab files on any of the nodes.
How do I locate and then remove these instances on nodes 2 and 3
ThanksSteps in Note 311350.1 have been followed, and there are no occurances of ASM appearing in the crs_stat output. Also the fact that the ASM software has also been removed from all of the various, where are these ASM instances being started?
I am unable to proceed past the "Select Configuration Screen" which gives you the option to 1)Create Database, 2)Configure ASM or 3) Install Software only.
When I select option 2 and enter ASM SYS password, I get the error message that ASM instances are present in the other nodes.
Would appreciate any help in how I can progress past this stage.

How to install ASM on 11gR2 on Windows?
hi *
can you suggest me how to install ASM instance with 11g R2 software ?
I don't need grid software as a whole.
My goal is to set standalone DB based on ASM storage.
In database server software (DBCA) I cannot choose "create ASM instance" . It's not there.
So I suppose I need to install some of grid software. But which part of it is sufficient that allows to configure ASM afterwards??
there are options:
- Installing and Configuring the Grid Infrastructure for a Standalone Server
- Installing and Configuring the Grid Infrastructure for a Cluster
- Upgrade Grid Infrastructure
- Install Grid Infrastructure Onlyg777 wrote:

- Upgrade Grid Infrastructure
- Install Grid Infrastructure OnlyFrom 11.2 onwards, ASM installation needs as a mandatory thing Grid Infrastructure. So if you want ASM,there can't be any thing else which you cna do except installing the Grid Infrastructure. The ASM maintenance has been removed from DBCA and is given now inthe ASMCA(ASM Configuration Assistant) which can only be run from Gird Infra home. So in short, the answer for your question is that you must install Grid Infrastructure if you want ASM , be it Windows or whatever o/s.

Want to move datafiles, controlfiles, redolog on new ASM Disks (11gR2 RAC)
Hi Guys,
Setup: Two Node 11gR2 (11.2.0.1) RAC on RHEL 5.4
Existing disks are from Old SAN & New Disks are from New SAN.
Can I move all datafiles (+DATA), controlfiles (+CTRL), redolog (+REDO) on new ASM Disks by adding disks in is same Diskgroup & dropping older disks from existing Diskgroup taking advantage of ASM Re-balancing Feature.
1) add required disks in the DATA Diskgroups,
ALTER DISKGROUP DATA ADD DISK
'/dev/oracleasm/disks/NEWDATA3' NAME NEWDATA_0003,
'/dev/oracleasm/disks/NEWDATA4' NAME NEWDATA_0004,
'/dev/oracleasm/disks/NEWDATA5' NAME NEWDATA_0005
REBALANCE POWER 11;
Check rebalance status from v$ASM_OPERATION.
2) When rebalance completes, drop the old disks.
ALTER DISKGROUP DATA DROP DISK
NEWDATA_0000,
NEWDATA_0001
REBALANCE POWER 11;
Check rebalance status from v$ASM_OPERATION.
3) Do it same for Redo log groups & Controlfile Diskgroups.
I hope, I could do this Activity, even if database is Up. is there possibility of Database block Corruption ??? (or is it necessary to perform above steps when database is down)
Would be appreciated, your quick responses on the same.
It's an urgent requirement. Thanks.

Hi Manish,
Yes you can do that by adding new disk to existing diskgroup and delete old diskgroup. The good thing is this can be done online however you need to make sure the rebalance power is meet your business time, higher rebalance power is faster to rebalance to complete however it also will consume more resources

Configuring networking for 11Gr2 RAC
Hi - I have a couple of questions regarding networking and RAC install.
Please could someone clarify what the Virtual IP requirement is for a RAC node, and how one would actually set this up on OEL5 using a DNS server.
All input appreciated - thxHi,

Please could someone clarify what the Virtual IP requirement is for a RAC node, and how one would actually set this up on OEL5 using a DNS server.You will need the concept before attempting to install because it is not possible to explain the concept of Oracle Clusterware Network (VIP/SCAN) with a few lines.

How to configure a Sun Type 7 Keyboard (Solaris 10 11/06)
Hi.
I bought a Sun Type 7 (UNIX) keyboard. I plugged it in and configured Xorg's kbd driver to use this kind of keyboard. The problem is that some keys, such as the 3 volume keys, the sleep key, the composite key, doesn't appear to work. In the official documentation there's no other installation hint but "to plug it in".
Has anyone any experience configuring this keyboard?
Thanks again,
Enrico.hello.
Just do this:
eeprom kbd-type=Frenchafter reboot.Hello,
"eeprom" is fine on a SPARC box, but how do I do this on a x86 box ?
TIA. -

Oracle 11GR2 rac installation in vmware

Oracle 11gR2 RAC with Sun clsuter 3.3 clsetup not showing ASMDiskGroup RS
Hello,
I am installing Oracle 11gR2 RAC on Solaris cluster 3.3 with hardware RAID and ASM
I was able to register rac-famework-rg and crs-framework-rg.
Oracle RAC is up and running (confirmed from crs_stat -t -v)
However, while creating option 5. Automatic Storage Management (ASM) on clsetup, I was getting ERROR: ASM is either not installed or the installation is invalid!
I have created the asm-inst-rg with resource asm-inst-rs and asm-dg-rg with resources asm-dg-fra, asm-dg-data and asm-dg-crs using CLI. Please find the complete clrg and clrs status output below:

Once I reach clsetup option 6: Resources for Oracle Real Application Clusters Database Instances, I was able to select cluster db name, oracle home, SID for both nodes, and it listed the asm-inst-rg and asm-inst-rs for selection of "Specify Oracle ASM Instance Resource".
The problem is the the next selection which is "Specify Oracle ASM Disk Group Resources" which does NOT list any asm-dg-rg or asm-dg-fra or anything, instead, it throws error "No existing disk-group resources available for selection. Run ASM subwizard create new resource(s) and come back to this panel for the selection."
Kindly guide me to create Resources for Oracle Real Application Clusters Database Instances either in CLI or clsetup
