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.

Oracle10g RAC with Oracle clusterware

Hi,
We are installing Oracle10g RAC with Oracle clusterware with ASM on Solaris 10. Does anybody have a installation/configuration manual for this combination.
Thanks,
Murtuja

Oracle10g RAC with ASM for stretch cluster

Assuming suitable network between sites is in place for RAC interconnect (e.g. dark fibre / DWDM), does it make sense (or is it possible) to stretch a RAC cluster across 2 sites, using ASM to mirror database files between SAN storage devices located at each site? The idea being to combine local high availability with a disaster recovery capability, using hardware that is all active during normal operation (rather than say a single RAC cluster on one site with Data Guard to transport data to the other site for DR).
Or, for a stretch cluster, would SAN / OS implemented remote mirroring be a better idea? (I'd have thought this is likely to incur even more overhead on the network than ASM, but that might be dependant on individual vendors' implementations).
Any thoughts welcome!
Rob

Please refer the thread Re: 11GR2 ASM in non-rac node not starting... failing with error ORA-29701

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)

RAC with ASM

Hi,
We will be implementing oracle 10g RAC with ASM.
Just wondering how many production systems are running on ASM.
Are there any known issues with ASM for performance and maintaince.
Please advice.
Thanks in advance.

Check more information about the difference between OCFS and ASM in metalink doc
Automatic Storage Management (ASM) and Oracle Cluster File System (OCFS) in Oracle10g
Doc ID: Note:255359.1
ASM provides many advantages over pure raw device, I believe it's fairly standard to use ASM together with RAC in 10g. And perhaps some files on OCFS2 that ASM doesn't handle.

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

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.

Best practice for oracle 10.2 RAC with ASM

Did any one tried/installed Oracle 10.2 RAC with ASM and CRS ?
What is the best practice?
1. separate home for CRS, ASM and Oracle Database?
2. separate home for CRS and same home for ASM and Oracle Darabase?
we set up the test environment with separate CRS, ASM and Oracle database homes, but we have tons of issues with the listener, spfile and tnsnames.ora files. So, seeking advise from the gurus who implimeted/tested the same ?

I am getting ready to install the 10gR2 database software (10gR2 Clusterware was just installed ) and I want to have a home for ASM and another for database as you suggest. I have been told that 10gR2 was to have a smaller set of binaries that can be used for the ASM home ... but I am not sure how I go about installing it. The first look at the installer does not seem to make it obvious...Is it a custom build option?

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:

Doc ID: NOTE:220970.1
At least crossover interconnect is completely unsupported.

Install CRS and RAC with different users

I' m tring to install CRS and RAC with different users.
It is supported but I don't find documentation.
Have someone experience with this configuration ?
My question are related to permission/own of voting and ocr file.
in this configuration is CRS owner or DB owner that run srvctl commands ?
Thanks !

Yes it is ... check out the RAC FAQ on metalink, and just as Chris metioned the users will need to have the oinstall group as their primary..
"Is it supported to install CRS and RAC as different users.
Yes, CRS and RAC can be installed as different users. The CRS user and the RAC user must both have "oinstall" as their primary group, and the RAC user should be a member of the OSDBA group.

SQLLoader issues of Oracle RAC with ASM

One of our client wants to use Oracle RAC with ASM for our application, i just want to know if there would be any two-phased commit transactions and SQL*Loader issues in ASM.
Database is Oracle 10g

ASM works only at storage layer and has nothing to do with:
- distributed transactions
- client executable that connects to database instance: SQL*Loader, SQL*Plus, etc.
RAC has also nothing to do with distributed transactions: a RAC database is a single database with multiple instances but still a single database; there is no need to use distributed transactions because you have a RAC database.

Installing oracle 11.2 rac with IBM Storwize V7000 san with aix 6.1

Has and one deployed 11g rac with IBM Storwize V7000 san with aix 6.1
Is this possible using Oracle CRS without going for OS cluster like GPFS

Hi lbn76,
Has and one deployed 11g rac with IBM Storwize V7000 san with aix 6.1
Is this possible using Oracle CRS without going for OS cluster like GPFS
I hope same thing will work with AIX 6.1 alsoNo problem, the procedure of installation of clusterware is the same in any AIX Platform.
If you are using Clusterware 11.2 you can (should) use ASM Diskgroup to place your clusterware files and database files. If you want use Cluster Filesystem to any other purpose you can use ACFS feature of ASM.
The Storage will be transparent to the ASM, the Luns will be mapped to AIX and ASM (Oracle) will manage the read and write.
The Storage Storwize have several great features, but are transparent to the ASM. The ASM will only see the LUNs provided by AIX.

How to convert single instance10g db to 11gR2 RAC with ASM

Hi,
I need your help to decide the plan about how to convert single instance 10g database to 11gr2 rac with asm.
I can have about 6 to 8 hours of downtime to upgrade and move to rac with asm.
db size is about 1.5tb and on AIX.
here is my plan....
1) install 11gr2 rac with asm on two nodes
2) verify rac installation and clustered asm
3)install 10g oracle binaries( yes 10g )
4) shutdown production db ( machine prod )
5) make copy of production and restore on 1st node ( using shadow image , so it's quick and its file system )
6) upgrade db to 11g ( still of file system )
7) after successful upgrade, move to asm ( rman backup )
8) add another node
does it look okay ? OR is there a better approach to save time?
can someone help me ?
Thanks...

Thanks ...
So here is what I thought... suggest if something is not right...
1) install 11gr2 grid infra on node A and B with ASM
2) stop CLUSTER ON BOTH NODES.
3) shutdown prod db on 10g ( downtime starts )
4) take rman cold backup
5) restore rman backup on node A on ASM ( as if single instance 11g , no rac parameters )
6) mount and run upgrade script for 11g, then open db with 11
7) after successful upgrade, shutdown db node A
8) change all rac related parameters, spfile,undo,redo for rac environment on both nodes
9) open db in rac environment
can I do this way ?
My only question is, even though I installed rac on node A and B, in step 5 and 6 I'm using only node A as if it is single instance. Is it possible ?
if it is then I'm good to go...
Thanks for all suggestions.

TNS-12520 when connecting via TCPS on 11gR2 RAC with SCAN Listener

I am struck trying to implement TCPS on our Oracle RAC SCAN Listener. I have added to our Oracle 12c systems, but not on a RAC with SCAN.
I created a wallet and certificate on one of the nodes, and copied it to the node and created auto login on each node. I exported the trust.jks and identity.jks, and loaded them in my test java program as the trust store and key stores. I have added the wallet location to the listener tns and sql ora files.
When attempting a TCPS connection, the ssl handshake succeed, but the client reports error:
ORA-12520, TNS:listener could not find available handler for requested type of server
The nodes scan listener log reports the TNS error, listener_scan1/alert/log.xml, when the connection is using TCPS on port 2484:

Hi hitgon,
Thanks first.
The commands output are as the following:
Command: srvctl status listener
Output:
# Listener LISTENER is enabled
# Listener LISTENER is running on node(s): rac1,rac2
Command: srvctl status scan_listener
Output:
# SCAN Listener LISTENER_SCAN1 is enabled

Output:
# ERROR:
# ORA-12520: TNS:listener could not find available handler for requested type of server
# Enter user-name:
By the way, rac-scan is the host where the SCAN listener is running and rac.localdomain is the service name. I've also tried the following commands
with the same error output:
sqlplus username/passwd@RAC
At last, i think the output of "lsnrctl status LISTENER_SCAN1" might help:

Is it possible make a RAC WITH WINDOWS XP?

is it possible make a RAC WITH WINDOWS XP?
i saw this link..
http://download-uk.oracle.com/docs/html/B10766_08/prewin.htm
and watch this information:
Operating System
RAC for Windows 32-bit is supported on the following operating systems:
- Windows 2000 with service pack 1 or higher. All editions, including Terminal Services and Windows 2000 MultiLanguage Edition (MLE), are supported.
- Windows Server 2003

If you have metalink access you can check the CERTIFY matrix....I just checked and looks like Oracle10gR2 RAC on Windows XP with both 32bit is not supported, but 64bit is.
