Shared Storage allocation for Oracle 10g RAC

Hi,
I am about to implement a Two Node Oracle 10g RAC on Windows 2008 (32-Bit) servers. We are going to use EVA4400 storeage and we have 600 GB for Oracle RAC and database.
I intend to follow the steps given in RACGuides_Rac10gR2OnWindows.pdf mentioned in Note 811271.1 (RAC Assurance Support Team: RAC Starter Kit and Best Practices (Windows)).
I would like to know how should I allocated the storage for OCR,Vote, Database and Flash Recovery Area. Meaning how many LUNs and of what size to be created and presented to both the servers. To start with I need to create a 25 GB database. We will be using Raw Device for OCR and Vote and ASM for Database and Flash Recovery Area.
Please advice.
Thanks,
Thiru

I am about to implement a Two Node Oracle 10g RAC on Windows 2008 (32-Bit) servers. Oracle 10g on Windows 2008 is not supported. Anyway installing a cluster as of today i would use a 64-bit operating system together with a 64-bit database. Everything else is not state-of-the-art anymore.
As of today i would go with 11g Release 1 (11.1.0.7.0) plus latest patches for Clusterware and ASM. Because you are using Windows 2008 you must use 11g Release 1 for the database as well. Bear in mind that Windows 2008 R2 is at this point in time not supported for 11g R1 or 11g R2 either.
I would like to know how should I allocated the storage for OCR,Vote, Database and Flash Recovery Area. Meaning how many LUNs and of what size to be created and presented to both the servers. This is said in the installation documents. Rule of thumb: At least three LUNs of 2 GB for OCR and three LUNs of 2 GB for Voting disk.
To start with I need to create a 25 GB database. We will be using Raw Device for OCR and Vote and ASM for Database and Flash Recovery Area.According to Oracles recommendations: Two disk groups: one for database files, the other for the flashback area.
But your setup may be different (more disk groups,....)

Shared Disk Subsystem for Oracle 10g RAC

I am investigating the feasibility of clustering two 220Rs together in an Oracle 10g RAC configuration. Can I use a D1000 disk array for the shared storage between the two nodes? Can you briefly describe how to do it or point me to documentation on how to do it?

hi dstmark,
can you kindly share some information with me? i am thinking of building up a small lab at home using A1000 to build up an Oracle RAC, as a1000 have 2 scsi port and have a build in controller.
but i am unsure about the detail software requirement, as google return some conflict information.
is SUN cluster would be enough? do i need to get something like Veritas Cluster? which may require a license key....
thanks for sharing information.

DO I need SFRAC for Oracle 10g RAC on Sun Solaris

My platform is SUN Solaris 10 64 bit on v490 server. On the backend side, we are using EMC CX500 storage. We will use Veritas File system and Veritas CFS.
I would like to ask, Do I must need SFRAC to configure Oracle 10g RAC or Can I just use only Oracle CRS. I do not want to use ASM.
Please advise
Thanks,
Sam..

The VCFS usually requires a Veritas Cluster, thus you would have to use the product combination that is bundled as SFRAC as mentioned before. Metalink in addition says:
10 10gR2 64-bit Veritas Storage Foundation for Oracle RAC 5.0 Certified
There is one exception to this rule: Linux.
Veritas and Oracle support a standalone version of the Veritas Cluster Files System (and only this component) on Linux. This does not hold true for Solaris.
Concluding, if you want to use the VCFS you would need to get a VCS, which then basically means using SFRAC.
However, in this case, as mentioned before, you would not need ASM.

Enable autoarchiving for Oracle 10g RAC db

Hello
What are the steps to enable autoarchiving for Oracle 10g cluster database?
It is currentrly in noarchivelog mode.
Thank you,
Yelena

Hi.
I think that this has been improved in 10g, so that we can do an exclusive mount on any database in a RAC without setting cluster_database to false. Also the parameter log_archive_start has been depreciated so the steps is simply (assuming that you by default wants to use db_recovery_file_dest to store archived redo logs)
1) Shutdown immediate (instance 1)
2) Startup mount
3) Alter database archivelog
4) Alter database open
Repeat this sequence for all nodes in the RAC.
And the best is to leave the log_archive_format by it's default value, to ensure that the incarnation of the database is represented in the archive log name.
(On 10g, backupsets and archivelogs are usable beyond different reincarnation of a database, so there is a good change that S% or s% will repeat itself after an open resetlogs).
Hopes this might help you.
Good Luck

Support for Oracle 10g RAC?

Will Oracle 10g RAC be supported in 8.1SP4? If so, when is it scheduled for release?
In the mean time, has anyone used 10g RAC and can share their experience?
Thanks,
Guy

First, tell us your current skill set - especially as it relates to Oracle database. Then we can give you the right advice.

Any idea about the pricing of the hardwares for Oracle 10g RAC?

Hi,
If I go for 2 nodes RAC using Dell servers and Disk array, any ideas about the prices? (just for the hardwares.)
Thanks.
Regards,
Jason

It's all about the shared disk(s).
If you are only ever going to use two (2) nodes a SCSI JBOD solution is cheap. (practical too with ASM as the cluster filesystem / volume manager)
More than 2 nodes, you step up to certified NFS, iSCSI or FC/AL connected storage. More expensive, faster, more flexible.
The computers are the cheapest portion of the cost especially with multiple core multiple cpu 64bit linux based servers being so inexpensive.

I have two questions for oracle 10g rac install for turbolinux11

this kernel 2.6.18-53
the first questions about asm
does asm`s disk only install a node (not install two or more nodes?)
the second questions:
does shall install oracle_clustware_10.2.1 or install oracle_10.2.1_datebase
when i install the oracle_clustware now i must be install datebase?????

Hi user10203064
the first questions about asm
does asm`s disk only install a node (not install two or more nodes?)
ASM instance shall be installed on both nodes
the second questions:
does shall install oracle_clustware_10.2.1 or install oracle_10.2.1_datebase
when i install the oracle_clustware now i must be install datebase?????´
You have to install first CRS, after that ASM and the database at the end

RH Linux VIP configuration not working for Oracle 10g RAC installation

Hi all,
I am trying to setup my test cluster on Oracle 10gR2 and Red Hat Linux 4. I have the public and private networks working fine and setup. However, after I setup the two VIP addresses, I cannot even ping these two virtual IPs from Linux. CRS install fails during initial run because it cannot communicate with the two VIP IP addresses. Can anyone help me out as to how to go about fixing the two VIPs so that Linux can ping them and CRS will install?
Thanks

It sounds like you configured your VIP on Linux in advance, before installing Oracle.
You are not supposed to do that.
Decide on an IP that the VIP will use with your network manager, but don't configure it in Linux. So before you start the clusterware install, ifconfig should not show your VIP.
CRS does not need VIP when you install the clusterware, only the interconnect address.
VIP is configured using a utility called VIPCA. If Clusterware installation fails and you think it was caused by VIP issues, try running VIPCA manually and let us know what were the results.

The best option to create a shared storage for Oracle 11gR2 RAC in OEL 5?

Hello,
Could you please tell me the best option to create a shared storage for Oracle 11gR2 RAC in Oracel Enterprise Linux 5? in production environment? And could you help to create shared storage? Because there is no additional step in Oracle installation guide. There are steps for only asm disk creation.
Thank you.

Here are names of partitions and permissions. Partitions which have 146 GB, 438 GB, 438 GB of capacity are my storage. Two of three disks which are 438 GB were configured as RAID 5 and remaining disk was configured as RAID 0. My storage is Dell MD 3000i and connected to nodes through ethernet.

Oracle 10g RAC using ASM - Storage Issue

I’ve an issue related to Oracle 10g RAC.
I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
I’ve EMC CX300 SAN storage with following partitions
/orasoft     10 Gb          OCFS2 File system
/oracrs          2 Gb          OCFS2 File system
/orabackup      100 Gb          OCFS2 File system
The datafiles are on ASM which is not directly visible in OS.
I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
I’ve faced an issue recently related to EMC storage.
The /orasoft partition displays 1.4 Gb space available using df command.
With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
Is this setup correct ??
Can anyone help me with this storage issue ??

Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
Here is what you can do:
- Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
- Create a ASM disk group which would mirror Disk_1 to Disk_2.
Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.

Thanks

Hi,
If you create a new diskgroup you may be to add the same diskgroup to parameter file or spfile and which will be needing down time.
sugestion: Instead of creating new diskgroup you should to add disk to existing group.if you add asm disk to existing group your all problem will be solved and Oracle itself will be managing all.And than i am sure no need to add entry in the parameter or spfile like +db_create_file_dest=.....

Oracle 10g RAC installation on HP-UX 11.31 for SAP ERP 6.04

Dear experts,
We are trying to install SAP ERP 6.0 EHP4 with Oracle 10g RAC on HP-UX 11.31. Please note that, We are using VERITAS cluster filesystem (CFS) for this purpose and not HP-UX ServiceGuard ClusterFileSystem.
*As per SAP procedure, we have installaed plain plain SAP system with single instance Oracle (ref: Configuration of SAP NetWeaver for Oracle Database 10gRAC guide). Now we are first trying to install Oracle Clusterware (CRS) and then we will install Oracle RAC software. Is this procedure right?*
Which file (and its path) we have to use for CRS installation and its patch? Is it runInstaller under /oracle/stage/102_64/clusterware? With this file we can install CRS 10.2.0.1. Similarly for Oracle RAC, which files we are supposed to use, i.e for installation and patch upgrade?
Also can we use clusterware package available from Oracle directly in the SAP environment?
We tried to install CRS with runInstaller while running Configuration Assistant after root.sh script.
The following commands are failing in Configuration Assistant:
/oracle/CRS/102_64/bin/racgons add_config erpprdd1:4948 erpprdd2:4948
/oracle/CRS/102_64/bin/oifcfg setif -global lan1/20.20.20.0:cluster_interconnect lan0/192.168.3.0:public
/oracle/CRS/102_64/bin/cluvfy stage -post crsinst -n erpprdd1,erpprdd2
1st command does not give any output if run manually.
2nd commands o/p: PRIF-12: failed to initialize cluster support services
3rd commands fails in every check
Please suggest the solution and expecting answers to the above mentioned questions.
Thanks & Regards,
Tejas

You can go for combined os migration and db release upgrade also at a stretch with the same downtime.

Installation of oracle 10g rac on open solaris for X86 Machine

Hi
Can you please let me know the advantages of installation of oracle 10g rac on open solaris on x86 machine.And also let me know the detail steps involved in instatllation of oracle 10g rac on open solaris on x86. please suggest the recommdendation for the installation
Thanks
Saiprasath

If by "advantages of installation of oracle 10g rac on open solaris on x86 machine" you mean advantages over RAC on Linux or AIX or HP/UX there aren't any.
If you want to know the advantages of RAC over stand-alone they generally relate to:
1. Eliminating the server as a single point of failure
2. Transparent fail-over
2. Incremental horizontal scalability
