Atypical ASM/RAC 11.2 configuration.

Hi every one,
We are evaluating several scenarios to implement Oracle RAC, and we want to know if the following configuration is certified by Oracle.
1 asm disk group (SAN)
1 linux node that has the following users and instances:
linux user: grid1 running asm instance-1
linux user: ora1 running db instance-1
linux user: grid2 running asm instance-2
linux user: ora2 running db instance-2
this node configuration is RAC with another linux node.
All asm instances share the same asm disk group
This configuration is because we have 2 core applications, each one with its own database, we only have 2 RAC Nodes and for security reason we want to separate database application and database administration.
Do you have any note o white paper that support this configuration?
Thanks.

Hi,
I would suggest to look at the installation guide for your platform. For 11.2 there could be either
1. only one oracle user for all installation
2. a role separation between a (storage,ASM,GI) and RAC RDBMS.
Regards,

Nodes in RAC One Node configuration

Dear all,
11.2 on Windows 2008
What is the maximum number of nodes we can have in RAC one node configuration ?
Yoosuf

Thanks Rafi and Sorry for not making it clear.
The whole configuration will be rac one node (With 4 nodes) with out dataguard implementation.
If the primary site goes down(s1,2 and storage) , can the secondary site wil be up automatically (s3,4 and storage). Please note storage is with ASM (normal redundancy ) primary storage at Head office and Secondary ASM storage at DR
Thanks

Oracle 10g R2 installation with ASM+RAC

Gurus,
Need some suggestuon on Oracle 10g R2 installation with ASM and RAC option.
We have found many documents on the Oracle, HP, HP-Oracle CTC and third party web sites, but nothing that is specific to this particular combination of separate
ORACLE_HOMEs, ASM and 10g RAC CRS. It is unclear for me from the documentation how this combination of ASM and 10.2g RAC may best be installed.
The high level steps i got after reading lot of docs as follows - but i am not sure whether these are correct or not. if they are correct, can any one share their experience/notes please?
1) Install CRS
2) Install RDBMS for ASM HOME - create separater oracle home for ASM instance using OUI
3) Install RDBMS for RAC Database Home - create separater oracle home for RAC database using OUI
4) Create ASM database using DBCA -
5) Use dbca to create database.

Oracle provides 'paint by numbers' tutorials called 'Oracle By Example'. (Go to OTN, check under the Training tab)
They have one for a Windows based ASM/RAC that you might want to review. Not your specific environment, but the steps will be dag-nabbed close.
I recommend walking the path (http://otn.oracle.com >> training:OBE >> Database 10g Release 1:VMWare:Installation

How to clone a 2-node ASM RAC db to a 3-node ASM RAC db by RMAN?

We need to clone a 2-node ASM RAC db to a 3-node ASM RAC db by RMAN. I would think this will be about the same as a regular single db procedure by RMAN mostly. However, in 3 node RAC, there will be additional instance thread in redo (thread 1,2, and 3). Questions will be
1. Should I use CRSCTL to add new instance (3rd)? -- I guess yes
2. Should I create additional online redo group for thread 3? -- I guess yes
3. Should I create addition undo tablespace? -- I guess yes
Can any body provide a procedure of cloning the DB?
Thanks!

Not just easy as next, next, next

ASM, RAC instance cloning

Hi,
Can you advice for cloning ASM, RAC EBS R12 instance , For lesser cloning time, is Snapshot mirroring or BCV copy of ASM, RAC instance of 20 TB in size is recommended?
Can we have BCV copy of it's replication used for faster RAPID cloning..Is there any white paper available for same.

Restoring RMAN Backup from ASM RAC env to Non ASM standalone environment

Hi,
Can anyone please tell me how to restore database using RMAN in a Non ASM environment as my backup file with ASM RAC environment.
i was also looking for some documentation which provides clear explanation about RMAN backup and Restore in ASM and Non ASM environment.
Thanks

You can set the parameter db_file_name_convert in init.ora in you new database with [ID 47325.1]
or
you can set parameter "set newname" in your script rman. [ID 549972.1]
if you have one or two destinations of dbfiles in ASM I seggest to you set parameter db_file_name_convert in init.
example:
db_file_name_convert=('+DGDATA','/u01/oradata/');
remenber you need set log_file_name_convert to.
log_file_name_convert=('+DGREDO','/u01/redo/');
if you use "set newname" commands you need set this lines in your script rman.
set newname for datafile 1 to '/u01/oradata/system01.dbf';
set newname for datafile 2 to '/u01/oradata/undotbs01.dbf';
set newname for datafile 3 to '/u01/oradata/sysaux01.dbf';
set newname for datafile 4 to '/u01/oradata/users01.dbf';
and every datafiles you need set!

Need RAC/ASM multinode flash cache configuration advice

We have a working two-node RAC database. We are installing a new 640gb fusion flash card in each node. The card is a double-card, so that it shows up as two devices: /dev/fioa and /dev/fiob on each node.
We have created two private disk groups, one on each node. The disk group on node 1 is "+FLASHCACHE" and the disk group on node 2 is "+FLASHCACHE2".
We haven't found any specific examples of how to configure the init parameters for flashcache on RAC/ASM. We are guessing that we should do the following. If someone would critique and confirm or suggest something different, we would appreciate it very much!
prod1.db_flash_cache_file='+FLASHCACHE/flash1'
prod2.dg_flash_cache_file='+FLASHCACHE2/flash2'
*.db_flash_cache_size=600G
Thanks for any advice.
Jim

Hi Jim,
prod1.db_flash_cache_file='+FLASHCACHE/flash1'
prod2.dg_flash_cache_file='+FLASHCACHE2/flash2'
*.db_flash_cache_size=600GYour configuration is correct.
Database Smart Flash Cache is not shared across RAC nodes; it is private to each RAC instance. For that reason, each RAC instance must define its own local flash cache file path. When the flash cache is managed by ASM, a separate diskgroup is needed for the flash cache of each instance.
You can use ALTER SYSTEM to set db_flash_cache_size to zero to disable the flash cache. You can also use ALTER SYSTEM to set the flash cache back to its original size to reenable it.
Read this white paper Oracle Database Smart Flash Cache

How to configure Oracle Enterprise Manager for ASM RAC Database ?

Dears,,
We have two databases (Primary & Standby), each database has two instances
Database version: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
How to configure Oracle Enterprise Manager for this environment ?
I need documentation for this please.
Many thanks & Regards,,

Assuming an agent is running on the servers you want to monitor,
navigate to the Agent home page (Via setup --> Agent)
When in the agent home page select 'Add Database'and press [Go]
Assuming yopur database now gets recognized, select the Configure icon and enter the password for dbsnmp.
When done, press [Ok] to return to the agent home page.

Oracle RAC on Solarais Configuration Issue

Hi,
We are trying to install Oracle RAC 10g R2 on Solaris 10.
Following are the products
1=> Soalris 10 OS
2=> Sun Cluster 3.1
3=> Veritas Volume Manager
4=> Veritas Cluster File System
Can i deploy Oracle RAC using the above listed Software.
Here we have not purchase any of the Cluster Volume Manager.
Is the CVM required to install Oracle RAC.
Is there any alternative wherein we can install Oracle RAC without using CVM like for example using the RAW device where the VM will manage storage from a single node rather than buying the CVM that will allow to manage the storage from multiple nodes.
Also i would like to highlight is suggestion for using ASM is rule out hence ASM would not be used.
Can anyone suggest me some solution to the above problem.

Well, my impression is that you don't really know what your requirements are and you are trying to fit the technologies somehow. Worse yet, there is no clear understanding how those technologies fit together and as long as you explain what your vendor is saying you (which vendor?) they don't have clear idea either.
I would also suggest to review your decision to use Sun Network Data Replicator for DR site. Consider Oracle Physical Standby database instead - it's more flexible solution and doesn't limit your choice of storage stack.
1) Do Oracle RAC 10gR2 requires any Veritas Cluster Volume Manager
Words "any" and "Veritas" contradict in your question. But the answer is no. RAC require shared storage which can generally be one of those:
- raw devices with or without some kind of cluster volume manager
- cluster file system
- NAS storage (NFS mounted)
- ASM with raw devices for CRS files (OCR and voting disks)
2) Does Oracle RAC 10g R2 require any Vertias Cluster File System or it can sit on normal Vertias File System
Again, Oracle database files MUST reside on shared storage and non-clustered file system is not an option.
3) Is there any solution where we can use the Sun Cluster with Veritas Componets to configure RAC.
If I recall correctly, Sun Cluster includes in it's license some of component of Veritas storage stack. So you might be all set. You should turn to documentation on that stage and see exactly what you have licensed and if your stack allows shared storage. You might want to have a look at http://www.sun.com/software/whitepapers/solaris10/solaris_cluster.pdf
and Oracle Certification Matrix on Metalink.

Installing ASM+RAC on two Sun Netra440

Hi, folks, My company develops a telecom system and considering to install RAC and ASM on two Sun Netra 440, each Netra 440 has 4 physic disks. We would like to use 2 physic disks on each Netra440 as a failure group, so a disk group comprise of 2 disks from first Netra440 and another 2 disks from second Netra440. then if one NEtra440 totally dies, then the other Netra440 can take care of application, because 2 local physic disks have the same data.
but how to configure ASM to access to second Netra440 disks from first Netra440? any suggestion is appreciated!

Hi,
I didn't hear anything about a shared device like a storage. If your company is able to afford 8 processor licenses for RAC then investing in a storage should not be a problem. That's the way I used to see and build Oracle RAC databases.
Good luck!
Cheers,
David

Patching method for ASM RAC environment

We are planning to apply new PSU, RAC bundle and CRS PSU for our pre-production environment. In oreder to reduce risk as well as downtime, we need a better approach for patching. Could you please clarify bellow concerns ?
1) Do we sync the ASM Oracle Home as per the RDBMS Oracle Home? - as per best practice we could see we supposed to sync up both oracle homes, but there are some one-off patches which meaned only for ASM home, thats why at present our ASM and RDBMS homes are not in sync. Could you please put some light on advantages and disadvantages of doing this.
2) We are planning to apply 11.1.0.7.1 PSU for RDBMS and 11.1.0.7.2 PSU for CRS. In this case do you suggest to apply RDBMS component of CRS PSU ?
3) For reducing downtime, we are planning to patch one oracle rdbms / ASM home and making a gold copy to clone all other nodes ? Is it a recommended method ? What is the risk involved in this ?
Thanks
Rupesh

1. The advantage patching both ASM and RDBMS homes is if ASM home is corrupted or some issues then you can start the ASM instance from RDBMS home will out any issues(bugs).
2.Yes, always it is recommended
3.Why you want a gold copy? Please note that if you have EM setup then configuration files are different between nodes. The best approach is applying patch local, so that you can reduce the downtime.
$ opatch apply -local
Hope this helps,

ASM/RAC dependencies

Dear DBAs,
while browsing the net to get documents related to the RAC, i found a document concerning the RAC/ASM dependencies and how to configure RAC services (CRS/ASM/DB instances) to run consecutively (or maybe you want to stop running a service at server startup).
The problem is that i lost this document and currently i need this information.
could you please provide me with a link concerning this subject ?
by the way my database is 10R2 path4
Thx in advance

Restoration of ASM/RAC database to another clustered set of servers for DataGuard implementation

Hi all,
I've been working with single instance Oracle DBs for several years and we're now looking into RAC. I'm trying to gather as much info as possible in areas I think may be challenging if/when we implement RAC.
Can someone please help me with some info with regards to the scenarion below:
Assuming I already have a 2 node RAC database running and I want to set-up a failover RAC database, would the following steps be correct(assuming 11g):
Configure hardware, networking and O/S for 2 node RAC cluster (I know there's a lot in this single line, but let's just assume that's all done)
Configure disks for ASM
Clusterware installation
Oracle ASM software installation
Oracle11g software installation with RAC option
Database creation
***I'm not sure of the steps after database creation:
Export primary database up to a specific SCN (data pump gives the ability to specify scn)
Import into failover database
Switch on dataguard and sync failover starting from scn specified at export.
Please, help correct these steps and any useful link where this process is treated thoroughly would be highly appreciated.

This is a very high level overview of the steps, but here are some additions/amendments I can make:
Clusterware installation
Oracle ASM software installation
-- The above 2 steps are done at the same time. In 11g, the Oracle 11g Grid Infrastructure includes both the Clusterware and ASM installation and configuration.
Oracle11g software installation with RAC option
Database creation
***I'm not sure of the steps after database creation:
Export primary database up to a specific SCN (data pump gives the ability to specify scn)
Import into failover database
Switch on dataguard and sync failover starting from scn specified at export.
Will you be using Data Guard for a physical standby? If so, using RMAN would be the correct method in creating the standby database. The general steps would be:
- Oracle 11g software installation
- Backup Primary Database
- Configure Data Guard Parameters on Primary
- Duplicate Primary to Standby RAC using RMAN (can be done manually or through the RMAN DUPLICATE command)
- Enable log transport from primary, enable managed recovery on standby, and verify log transport and apply is working as intended.
Again this is a very general overview on the entire process, there are other factors that you'll have to take into consideration when planning such a project:
- Which protection mode will you be using? Maximum Performance, Availability, or Protection? The business' recovery goals and SLAs will be able to determine which mode you will choose.
- Will the standby be used for reporting purposes?
- Recommended to have your standby site have the same hardware configuration as the primary.
- Do you have an EM site already set-up? Data Guard Broker should be considered in the configuration of the Data Guard environment.
This is just a few things quickly off the top of my head. What OS do you have/plan on using? I don't have the link handy on me at the moment, but the official Oracle documentation should provide detailed guidance.
EDIT:
At a bare minimum, read the 2 Day RAC Guide. There is more detailed information in the RAC Admin and Deployment Guide, as well as the Data Guard Concepts and Admin Guide. Also here's a step-by-step guide provided by Oracle. You can also find several blogs that provide a more concise step-by-step guide, such as here, here, and here. RACSIG also has a number of very useful whitepapers, but something seems to be wrong with their search function and I can't link anything at the moment. However, I would highly recommend reading through the official documentation as this has more comprehensive information, especially if you are deploying on a production system.

Oscar
