Need Document/Steps for Cloning RAC 11g.

Hi,
I am looking for a document to clone an existing RAC 11g database.
I believe in the cloning process this will create a new RAC database...
Also the source database data has to be applied to the cloned rac db.
Environment 11g, AIX.
Advice needed.
Thanks in advance.

Hello Indigo,
The steps are necessary,
1) Create the password file
2) Create the spfile for the DESTINATION database (auxiliary database)
3) Create the necessary mount points or the folders for the database files
4) Execuute this command from the primary database.
DUPLICATE TARGET DATABASE TO <standby_name>
FOR STANDBY
FROM ACTIVE DATABASE
SPFILE
PARAMETER_VALUE_CONVERT '<string>', '<string>'
SET DB_FILE_NAME_CONVERT '<string>', '<string>'
SET LOG_FILE_NAME_CONVERT '<string>', '<string>'
SET SGA_MAX_SIZE 1000M
SET SGA_TARGET 850M;
Please see the *11g : Active Database Duplication ID 568034.1*

Needed: Manual Steps for Uninstalling QT 7 on XP SP2

I've searched through a lot of posts with no luck.
I need a simple list of instructions to Manually uninstall QT7 because it does not appear in the add/remove programs list.
thanks for the help - Josh

Nothing on the search. i had the same icon in the folder (start, all programs, quicktime, uninstall), but it did nothing. it was looking for some file that isn't on my machine. i can't remember what it was called now, but i did a search on it and came up with nothing. Do you think reinstalling qt might add the missing files back in?

while there other Linux versions are also vertified, best is to use Oracle Linux http://www.oracle.com/us/technologies/linux/index.html

Raw Storage device for 10g RAC

Hi
What would be economical & of good quality RAW storage device for 10g RAC setup
Thanks
JIL

Sorry, but what do you mean shared networK?
Yes you need to ensure 2+ server hosts can access the storage array, but if you array can handle multiple direct connections then this is perfectly acceptable for RAC - this is Direct Attached Storage DAS.
Your original post made me think of NAS which may not be what you were meaning, but is how I read network device - NAS, NFS kinda thing - which is NOT a requirement for RAC.

Steps for data guard RAC primary RAC standby

Hi,
I have some doubt in configuring data guard for rac DR to rac primary.
1) In RAC DR, physical standby will be in RAC before starting data guard for RAC Primary , right?.
2) While configuring RAC DR , should one node be down in standby?.
3) After creating the auxiliary database in standby, i mean restoring the rman backup from staging directory in DR,
Shall we have to register the services(database,instance,asm,etc..) to CRS(OCR)?. If yes ,Why?.
4) After DR configure over , Shall i shut/down one node?. Should all the nodes in DR be in up , while applying logs to
standby ?.
If anybody have made the setup and have the prepared document , requesting you to share with me.
Thank you very much,
Sunand

Hi Sunand,
Please follow the following My Oracle Support (MOS) Document ID:
MAA - Creating a RAC Physical Standby for a RAC Primary [ID 380449.1]
For further details, see the referred documents in previous post. Try practicing on VMWare because it will give you the flexibility for creating snapshots to save your work. Please see the answers for your question below:
Q1. In RAC DR, physical standby will be in RAC before starting data guard for RAC Primary , right?.
Answer: Yes, this is recommend but not mandatory. You can add a second node later on.
Q2. While configuring RAC DR , should one node be down in standby?
Answer: Yes, there are some database configuration commands that should be run in exclusive mode. You can start the remaining instance(s) after DB creation. Do not forget to set CLUSTER_DATABASE parameter to TRUE. Also, all instances except one should be close while performing switchover/failover.
Q3. After creating the auxiliary database in standby, i mean restoring the rman backup from staging directory in DR, Shall we have to register the services(database,instance,asm,etc..) to CRS(OCR)?. If yes ,Why?
Answer: Yes, this is recommended for RAC configuration to take advantage of high availability services.
Q4. After DR configure over , Shall i shut/down one node?. Should all the nodes in DR be in up , while applying logs to
standby ?
Answer: You can start up all the instances after DR creation. In this case if your one node goes down log apply services will continue to apply changes in DR.
Hope, this helps to clear your questions.

Shahid

Why do we use reverse proxy for Oracle RAC Cluster setup

Hello All,
I got this question lately.. "why do we use reverse proxy for Oracle RAC Cluster setup". I know we use the reverse proxy at Middleware level for multiple security reasons.
Thanks..

"why do we use reverse proxy for Oracle RAC Cluster setup".
I wouldn't. I wouldn't use a proxy of any sort for the Cluster Interconnect for sure.
Cheers,

RAC setup for R12

Hi,
I read docs about EBS R12.1 RAC setup that said:
The traditional and still widely-used configuration where the Concurrent (Parallel) Processing servers
are located on the database tier. Unless there is a network constraint, the recommendation now is
to place them on the application tier for greater flexibility and scalability.Right now we have a multi node setup (not yet on RAC) , the AppsTier is on node1 (including the Concurrent Managers which is the default setup), while the Db-Tier is on node2. Does this mean I do not need to transfer anymore the Concurrent Manager to the Db-Tier on node2?
Are Concurrent Managers also referred to as the Concurrent Processing servers?
If my Concurrent Managers are located on the AppsTier, How can I convert it to Concurrent Paralllel Processing servers? Can you please give me notes on how to setup this type of configuration?
Thanks a lot,
Msk

Hi,

Does this mean I do not need to transfer anymore the Concurrent Manager to the Db-Tier on node2?You have the option of moving the CM to the database node, but it is not required here (recommended to keep it on the application tier node where you have it running now).
Are Concurrent Managers also referred to as the Concurrent Processing servers?Yes.
If my Concurrent Managers are located on the AppsTier, How can I convert it to Concurrent Paralllel Processing servers? Can you please give me notes on how to setup this type of configuration?See the docs referenced in this thread.

Hardware required for RAC setup at home

Hi All,
Could you please suggest the Hardware required for practicing RAC at home.
Regards,
VN

Hi, "user7202581",
For practicing purposes, you could consider a VBox / OVM based setup at home. We have used those for Hands On Labs in the course of Oracle Open World more than once. I recommend you use a machine with at least 8GB memory and dual core (HT enabled) processors. Some configuration examples: Lenovo Laptop, ThinkPad, 8GB, 320GB HDD, i5 dual core, 2.5 GHz, Win 7 or a Mac Mini, latest version, i5 dual core, 2.3GHz and 8GB memory would do the trick for a two node cluster. Note that I mention the hosting OS in case you use VBox. For OVM based setups you either have to use a dual boot system or use a dedicated machine. You will be somewhat restricted with respect to the hardware failures you can impose on this system obviously (due to the VM setup), but for practicing purposes, you should find those environments sufficient, I think. Also see: RAC on OVM templates: http://www.oracle.com/technetwork/server-storage/vm/rac-template-11grel2-166623.html
Hope that helps. Thanks,
Markus

ISCSI Recommendations for RAC Setup

Hi all,
My company is interested in setting up Oracle RAC for back-of-house processing (all traffic would be internal...no client facing apps or anything) and are looking to do so by using an iSCSI shared storage device. We are currently using the Dell MSD3000i in an Oracle fail-safe solution, but I'm not 100% confident that it will be able to handle a RAC setup. Has anyone out there had any experience using this device with RAC? Any recommendations out there from someone who has had good experiences with a similar device?
The vision for the current setup is having a two-node RAC with two quad-core servers running Windows 2008 64-bit with 32 GB of RAM each. We would be running Oracle Standard Edition.
Any feedback given would be much appreciated.
Thanks,
Joe

Hi
1) Oracle does not certified hardware, but Oracle RAC certifies storage technologies as Fiber channel, SCSI and iSCSI. Please take a look to: http://www.oracle.com/technology/products/database/clustering/certify/tech_generic_window_new.html
2) With your storage device i think this link could help you:
http://www.dell.com/downloads/global/solutions/FINAL_10gR2_SE_RAC_on_MD3000i_RefConf_v1%203.pdf?c=ae&l=en&s=bsd
But it is on linux, maybe you can switch to Red Hat or Oracle Enterprise Linux.

Miguel.
