Testing Oracle10g RAC

Hi,
I want to test Oracle rac availability and load balancing.
Does anyone know some useful document, link or have an idea how to simulate failover?
Thanks

how about the obvious: pull a cable

Recover Oracle10g RAC Database

Hi,
Anyone know whether the below backup and restoration works for oracle10g RAC database. I can;t test it out as i don;t have an development environment. Please correct me if i am wrong.
1.) stop all oracle services running on the server
2.) use dd command to backup the raw partition to tape + backup oracle homes on all nodes
3.) Encountered Media failure, change the hardisks
4.) create the raw partitions
5.) restore the raw partitions backup from tape + restore oracle binaries from tape
6.) startup all oracle services
7.) Done.
Thank You, anyone advice and comments are greatly appreciated..

Many thanks for your responses . I finally got it working . It does not require additionalconfigurational change apart from updating the ocr with oifcfg commands(metalink-Note 283684.1 ) i.e. deleting the old entry and setting he new one .
Where I got it wrong was I did not shutdown the nodeapps (which was not included in the metalink note ) before updating the ocr with oifcfg commands
Thanks ..

Oracle10g RAC Cluster Interconnect issues

Hello Everybody,
Just a brief overview as to what i am currently doing. I have installed Oracle10g RAC database on a cluster of two Windows 2000 AS nodes.These two nodes are accessing an external SCSI hard disk.I have used Oracle cluster file system.
Currently i am facing some performance issues when it comes to balancing workload on both the nodes.(Single instance database load is faster than a parallel load using two database instances).
I feel the performance issues could be due to IPC using public Ethernet IP instead of private interconnect.
(During a parallel load large amount of packets of data are sent over the Public IP and not Private interconnect).
How can i be sure that the Private interconnect is used for transferring cluster traffic and not the Public IP? (Oracle mentions that for a Oracle10g RAC database, private IP should be used for heart beat as well as transferring cluster traffic).
Thanks in advance,
Regards,
Salil

You find the answers here:
RAC: Frequently Asked Questions
Doc ID: NOTE:220970.1
At least crossover interconnect is completely unsupported.

Why we need CRS in Oracle10g RAC

When i am having third party cluster solution like Veritas(SFRAC for Oracle), why its not possible to configure Oracle10g RAC with Veritas without CRS ?????
Its possible in Oracle9i but why not in Oracle10g ????

because ASM is there !!!
in 10g you do not have to use raw devices to store data files : you just use the ASM instance which comes free and provides the performance of the raw devices with the management capabilities of any filesystem
you only need to configure raw devices for the OCR and Voting Disk (but this is really simple !!! compared to the management problem of storing datafiles on raw (no autoextend , mapping and so on)

Solaris cluster, Oracle10g RAC

I just want to understand, which one is more favorable, most popular combination used by sun customers for Oracle10g RAC.
1) Solaris cluster + VERITAS Storage Foundation
2) Solaris cluster + QFS

Please refer to http://docs.sun.com/app/docs/doc/820-2574/fmnyo?a=view for the supported options for Oracle RAC data storage. This is important because if you stray outside these you will not be on a jointly Sun/Oracle supported configuration.
Therefore, if you want to put Oracle RAC (tablespace) data files on a cluster file system, you must use shared QFS as that is the only supported option open to you. Furthermore, you can only run sQFS on top of SVM/Oban or h/w RAID - we do not support running it on VxVM/CVM.

Oracle10g RAC vs Oracle9i RAC with WebLogic

Hello, I am planning on installing Oracle RAC on Redhat's Linux AS 3.0, while BEA's WebLogic will the application server.
What would you choose as the back end, Oracle9i RAC or Oracle10g RAC and why ?
Also, what release/patch-level (sp ??) of Linux A.S should be used ?
EMC's storage disk arrays sould be used. Is anyone aware of any I/O issues between Linux AS and EMC disks ?
Thank you for your thoughts.
Regards,
Tom

Sun would not recommend using Oracle 10g RAC without Sun Cluster. Setup for that configuration would be found in the Sun Cluster Data Service for Oracle 10g RAC and the Oracle installation manuals.
The installation of Oracle Clusterware alone would be documented in Oracle's manuals. If you have any problems with that, you are better off asking Oracle.

Benchmark of Oracle10g RAC

Hi,
Does anyone know where I can find the benchmark of Oracle10g RAC (2 nodes or more ) on Sun Solaris?
Thanks

You may find this posting helpful for using free benchmark tool for oracle.
http://www.oraclepoint.com/topic.php?filename=166&extra=page%3D1 (register and then log in because it's only available for members.)
There are step-by-step installation guide and sample report of TPC-C.
Hope it helps.

Oracle10g RAC

Hi,
Can anyone help me,
Is there any problem for Oracle10g RAC running on Sun Solaris 10 using the latest SUN Containers feature?
regards,
Dilip.

Have a look at the Certify & Availability in Metalink for your Platform. Also the RAC Readme and documentation for Sun Solaris 10 will indicate if there are any known problems.
If in doubt and you are having any specific problems, I would suggest you open a TAR with Oracle Support.

Oracle10g RAC with Oracle clusterware

Genclntst fail in oracle10g RAC environment

After installation of oracle 10gR2 RAC on two-node solaris10 environment ,we need to run $ORACLE_HOME/bin/genclntst to generate the Client Static Library(libclntst10.a) but it failed .We copy another successfully generated libclntst10.a file from a non-RAC oracle10g environment running on solaris10.
and it seems to work correctly. is it really OK ?,is there any difference between the libclntst10.a file in a RAC environment and in a non-RAC environment ?
thanks a lot.

Hi,
In 11g you can use the instance_id job attribute to do this.
In 10g you can do this using services.
- create a service for each instance
- create a job class pointing to each service
- grant execute on the job classes to all job owners that need to use them
- when creating a job point to the job class for the service for the instance it should run on
Oracle recommends using services instead of instances since services are more flexible and can provide high-availability and fail-over in case one instance goes down.
Hope this helps,
Ravi.

Create password file Oracle10g RAC

Hi all,
we have Oracle10g R1 (64 bit) running on RAC Unix. these servers (2 servers and 2 instance) are using RMAN and the logs are transfered to DR server ( only 1 server). i dun have any idea on how to create password file with this structure, originally we want to change SYS password. and how to create password file at both RAC server and DR server, make sure the logs be transmitted without problem to DR server.
would like to the exact procedure ...any idea?
many thanks in advance.
Regards,
Nonie

to change SYS password. and how to create password
file at both RAC server and DR server, make sure the
logs be transmitted without problem to DR server.
Have not you created password file on Database and DG ? use orapwd command to create password file. Well changing password on Database side, is same simple procedure, but on DR you can change password in password file , but problem is how to change password on DR database. So only option remain is refresh DR Database !!!!

Oracle10g RAC 구성에서 CRS 오류로 Oracle이 재시작 되는 원인

oracle10g Release 10.2.0.1.0, SunOS(sparc, Sun-Fire-V890) 2대로 RAC 구성,
Oracle CRS를 사용하고 있습니다.
시스템이 정상적으로 운영되고 있어, alert 로그 점검을 소홀히 하고 있었는데,
오늘 아래와 같이 alert 로그를 점검 결과 최근 3개월 동안 약 3회정도 오라클이 CRS에 의하여 Shutdown 되었다가 Startup 되었습니다.
CRS 에러가 왜 발생되었는지, 어찌 하면 해결할 수 있는지 알고 싶습니다.
고수님의 조언 부탁드립니다.

Oracle10G RAC install on Solaris 10

Please suggest some good and simple install document for Oracle 10G RAC on Solaris 10 Sparc?

In my opinion I would not use physical shared storage at all.
Get VMWare Server, a suitable OS and a big hard disk and one PC with lots of RAM.
Use this to create your RAC environment. It works perfectly and is much easier than using multiple devices which require multiple network cards and suitable storage.
I have a Dual Core PC running XP with 2GB RAM. You can get RAC working with 2 VM's each allocated 512MB which will do for learning purposes. This also has an advantage I can take it with me when I am away from home.
