Best OS for Oracle RAC 10 G

I'm about to set up an Oracle 10 g RAC, which OS should I choose? Red Hat Linux? Win 2003 Ent? Any known problems with any OS that I should avoid?

I think the other thing to consider is the level of support for the platform. My thoughts are:
- Linux: Lots of support from a lot of big players, including IBM and Oracle. Should be a player for at least a few more years.
- Windows: It's hard not to hate it, but it does the job quite well these days.
- Solaris: Nice OS, but do you buy Sparc, x86-32 or x86-64. Also, where do SUN really see Solaris going in the next few years. All of a sudden Solaris x86 is hot, but it wasn't so long ago they ditched it as a bad job. They would rather sell Sparc if the market would let them, so how commited are they to x86 really?
- HP-UX: Nice OS, but HP-UX on PA-RISK is on its way out, like TRU64. HP talk about HP-UX on Itanium, but if they had their way we would all be using Linux so they could get out of the game. I don't believe they are really commited to an OS anymore.
- AIX: Seems to be having an upturn of late, but IBM are pushing Linux heavily, so what's their real plan?
If I were starting a new RAC installation, my money would be on Red Hat Enterprise Linux, but there is a lot to consider. If you're a Windows shop, then the learning curve for Linux will be quite big...

Any Oracle best practice/standards for inter-DataCente links for Oracle RAC

Hello Oracle Experts,
Am working for a customer to set up Oracle RAC architecture hosting SAP/Non-SAP applications per SLA levels(MC/BC/Standard) specs. Currently my network team needs calculation to arrive at whether we will go for a (1), (2) or (3) 10Gig links for inter DC (Data-Center) for Oracle RAC.. below is additional background:
•     Porting all client SAP/Non-SAP Oracle databases to new 2 data-centers.
•     There will be 10 blades (4x BL680s and 6x BL460s) in each DC (can scale-up/out later on).
•     Clusters architecture to support Extended/Stretched RAC cluster feature
•     Clusters 2-node each(1-datacenter1, 1-datacenter2) and nodes distributed across 2 x c7000 such that no cluster has more than one node in an enclosure.
•     Each node will have - 4 NIC ports ( 2 x public and 2 x private) , 2 dual-port HBA
•     Oracle ASM/ACFS (ASM Cluster File System), Voting Disk, OCR and Database files
•     the versions are Oracle 11g RAC, Oracle 10g RAC and Oracle 9i (for DataGuard/Standby) on RHEL 6 on Proliant Blades (x86) + BladeMatrix
My network colleagues considering using DWDM across the 2 DCs(given the lesser cost?). Am still looking around if there are any Oracle/industry-best practices around this and having a calculation to support that..
Many Thanks in advance..

Abhijit

Hi ,
There are no specific set of steps / practices for batch loading contents to ucm . It would be very much dependent on how many contents does the user have to load to UCM and how well the server is configured in terms of performance .
You can get more details from the following documentation link : http://docs.oracle.com/cd/E21043_01/doc.1111/e10792/c02_settings009.htm

Adding Box for Oracle RAC(Clustering) to BIW 3.5 Oracle/Linus

Hai Gurus,
Suppose if we have 1 box with Bw3.5 Linux/Oracle and add another box to do Oracle RAC(clustring). Do we need to re-instal the Box 1 also or we can do that with small configuration changes.
Guide me.
Regards,
Mano

Hi Mano
As in most cases there is a short answer and a longer one. Short:
If your system is RAC ready, switching from single instance to cluster database and adding a new node is quite simple. From pure application side there will not be major changes necessary.
Long:
What do i need for oracle RAC, what do i have to do to make my system RAC ready?
Hardware / OS
You will need shared disks, cluster fs, on linux mostly OCFS2. If you don't have it yet, you need to get it and move your database on to it. You would probably need an additional lan interface for the interconnect.
Oracle / Database
You would have to install CRS, that is the oracle cluster software. Your oracle instance, listener will run as services controlled by CRS when RAC is enabled. You will need to configure separate redo threads and undo tablespaces for each node you add. Not least you would probably need an additional costly RAC extension license from your favorite oracle sales rep.
SAP
You should think about separate enqueue server and enqueue replication, although this is not mandatory. This is dependent on your reasons for using RAC. If it is high availability you should go for it.
This is not a complete list, i just wanted to give you an initial idea, please ask if you need further details. If you start into RAC just now, you will have a long way to go, otherwise the short answer will apply.
Best regards
Michael

OIM 9.1.0.2 - Weblogic JDBC Multi Data Sources for Oracle RAC

Does OIM OIM 9.1.0.2 BP07 support Weblogic JDBC Multi Data Sources (Services>JDBC>Multi Data Sources) for Oracle RAC instead of inserting the "Oracle RAC JDBC URL" on JDBC Data Sources for xlDS and xlXADS (Services>JDBC>Data Sources> xlDS|xlXADS > Connection Poll> URL) ?
If yes, is there are any other modifications that need to be made on OIM, or just changing the data sources?

Yes, it's supported. You install against one instance directly of the Rac Server. Then you update the config.xml file and the jdbc resource in your weblogic server with the full rac address. It is documented for installation against RAC. http://docs.oracle.com/cd/E14049_01/doc.9101/e14047/database.htm#insertedID2

Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

Hi all,
Need some help from all out there
In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
ora-29701 *Unable to connect to Cluster Manager*
during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesnt work anymore when the server is rebooted.
Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.

Fixed in Product Version No Data
Problem statement:
ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
*** 03/25/05 07:32 am ***
TAR:
PROBLEM:
Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
While creating the database, customer receives following error:
ORA-29701: unable to connect to Cluster Manager
However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
DIAGNOSTIC ANALYSIS:
It seems that the problem is with libskgxn9.so shared library.
For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
installActions2005-03-22_03-44-42PM.log:,

For 9.2.0.4 -> 9.2.0.6, install log shows:
installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
WORKAROUND:
Customer is using the following workaround:
cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

Gig Ethernet V/S SCI as Cluster Private Interconnect for Oracle RAC

Hello Gurus
Can any one pls confirm if it's possible to configure 2 or more Gigabit Ethernet interconnects ( Sun Cluster 3.1 Private Interconnects) on a E6900 cluster ?
It's for a High Availability requirement of Oracle 9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster interconnect for Deploying Oracle RAC on E6900 ?
2) What is the recommended Private Cluster Interconnect for Oracle RAC ? GiG ethernet or SCI with RSM ?
3) How about the scenarios where one can have say 3 X Gig Ethernet V/S 2 X SCI , as their cluster's Private Interconnects ?
4) How the Interconnect traffic gets distributed amongest the multiple GigaBit ethernet Interconnects ( For oracle RAC) , & is anything required to be done at oracle Rac Level to enable Oracle to recognise that there are multiple interconnect cards it needs to start utilizing all of the GigaBit ethernet Interfaces for transfering packets ?
5) what would happen to Oracle RAC if one of the Gigabit ethernet private interconnects fails
Have tried searching for this info but could not locate any doc that can precisely clarify these doubts that i have .........
thanks for the patience

Can any one pls confirm if it's possible to configure
2 or more Gigabit Ethernet interconnects ( Sun
Cluster 3.1 Private Interconnects) on a E6900
cluster ?Yes, absolutely. You can configure up to 6 NICs for the private networks. Traffic is automatically striped across them if you specify clprivnet0 to Oracle RAC (9i or 10g). That is TCP connections and UDP messages.
It's for a High Availability requirement of Oracle
9i RAC. i need to know ,
1) can i use gigabit ethernet as Private cluster
interconnect for Deploying Oracle RAC on E6900 ? Yes, definitely.
2) What is the recommended Private Cluster
Interconnect for Oracle RAC ? GiG ethernet or SCI
with RSM ? SCI is or is in the process of being EOL'ed. Gigabit is usually sufficient. Longer term you may want to consider Infiniband or 10 Gigabit ethernet with RDS.
3) How about the scenarios where one can have say 3 X
Gig Ethernet V/S 2 X SCI , as their cluster's
Private Interconnects ? I would still go for 3 x GbE because it is usually cheaper and will probably work just as well. The latency and bandwidth differences are often masked by the performance of the software higher up the stack. In short, unless you tuned the heck out of your application and just about everything else, don't worry too much about the difference between GbE and SCI.
4) How the Interconnect traffic gets distributed
amongest the multiple GigaBit ethernet Interconnects
( For oracle RAC) , & is anything required to be done
at oracle Rac Level to enable Oracle to recognise
that there are multiple interconnect cards it needs
to start utilizing all of the GigaBit ethernet
Interfaces for transfering packets ?You don't need to do anything at the Oracle level. That's the beauty of using Oracle RAC with Sun Cluster as opposed to RAC on its own. The striping takes place automatically and transparently behind the scenes.
5) what would happen to Oracle RAC if one of the
Gigabit ethernet private interconnects fails It's completely transparent. Oracle will never see the failure.
Have tried searching for this info but could not
locate any doc that can precisely clarify these
doubts that i have .........This is all covered in a paper that I have just completed and should be published after Christmas. Unfortunately, I cannot give out the paper yet.

Copper cable / GigE Copper Interface as Private Interconnect for Oracle RAC

Hello Gurus
Can some one confirm if the copper Cables ( Cat5/RJ45) can be used for Gig Ethernet i.e. Private interconnects for deploying Oracle RAC 9.x or 10gR2 on Solaris 9/10 .
i am planning to use 2 X GigE Interfaces (one port each from X4445 Quad Port Ethernet Adapters) & Planning to connect it using copper cables ( all the documents that i came across is been refering to the fiber cables for Private Interconnects , connecting GigE Interfaces , so i am getting bit confused )
would appretiate if some one can throw some lights on the same.
regards,
Nilesh Naik
thanks

Cat5/RJ45 can be used for Gig Ethernet Private interconnects for Oracle RAC. I would recommend trunking the two or more interconnects for redundancy. The X4445 adapters are compatible with the Sun Trunking 1.3 software (http://www.sun.com/products/networking/ethernet/suntrunking/). If you have servers that support the Nemo framework (bge, e1000g, xge, nge, rge, ixgb), you can use the Solaris 10 trunking software, dladmin.
We have a couple of SUN T2000 servers and are using the onboard GigE ports for the Oracle 10gR2 RAC interconnects. We upgraded the onboard NIC drivers to the e1000g and used the Solaris 10 trunking software. The next update of Solaris will have the e1000g drivers as the default for the SUN T2000 servers.

What is the best platform for Oracle Server?

What is the best platform for Oracle Server?
What is your criterion?
Thanks,
Somsak B.

I believe that Oracle is developed and coded on a Solaris
platform and then ported to other operating systems. If that is
the case, you can assume that Solaris is the best platform or at
least the safest in terms of performance and risk.
If anyone knows anything to the contrary, pls correct me.

Best tool for Oracle Fusion.

I have not explored this, but, does Selenium recognize Oracle Fusion related Objects (Fields in the web pages).
Or, OATS (with ADF Accelerator) is the best option.

Hi,
I feel OATS is the best fit for Oracle Fusion Applications, it comes with in built ADF Accelerators.

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.

Considering shared storage for Oracle RAC 10g

Hi, guys!
My Oracle RAC will be run on VMware ESXI 5.5. So, both 2 nodes and shared storage are on VM. Don't blame for this, I dont have another choice.
I am choosing shared storage for Oracle RAC. I am choosing between NFS and ISCSI server, both can be done in RedHat linux or FreeNAS.
Can u, guys, help me to do the choise?
RedHat or FreeNAS
ISCSI or NFS
Any help will be appreciated.

JohnWatson написал(а):
NFS is really easy. Create your zero-filled files, set the ownership and access modes, and point your asm_diskstring at them. Much simpler than configuring an iSCSI target and initiators, and then messing about with ASMlib or udev.
I recorded a public lecture that (if I remember correctly) describes it here, Oracle ASM Free Tutorial
I will be using OCFS2 as cluster FS. Does it make any difference for NFS vs ISCSI?

Need clarification for firmware & MPIO version for Oracle RAC

Dear All,
We have two-node Oracle RAC configuration 10gR2, Windos 2033 R2, 64-Bit OS using ASM and Oracle 11gR1 clusterware on HP Blades. The SAN storage is from IBM. We want to upgrade the firmware and MPIO version as per vendor recommendation.
Is there any requirement for Oracle RAC to have specific version of firmware and MPIO? Is there any matrix available for this? Or is it like both nodes should be able to see same SAN storage (LUN) irrespective of version used?
Thanks

Please note that Oracle RAC doesnt have requirement any sepcific firm ware. If you upgrade the firmware, it should not break any existing config, so pls check with IBM.
Also if you are doing any specific firmware upgrade then IBM should provide the supported version list.
Hope this help,

Linux set up for Oracle RAC (real application cluster)

Hi Guys,
I m wrkig as Oracle DBA.
Very curious to know the initials for RAC set up at OS level.
Can anyone provide his/her usefull guidelines for the same.
Although I know all steps at OS level also, but didn't did the set up of before Oracle RAC installation.
Want to increase knowlegde on like:
--how we sahre storage.
--how we set up network (private & virtual IP) and how can check working of NIC's.
--and other required things.
Will appreciate ur help and if someone want to share his/her personal experience.
Thx in advance.

Want to increase knowlegde on like:Here are very basic answers to very complex questions - from a pure Linux perspective running an Open Source stack and untainted kernel.
--how we sahre storage.Using multipath - this should ship with most 2.6 kernels. The kernel sees the shared storage LUNs as scsi devices - multipath does the rest. (and ASM can directly use a multipath device).
On a physical layer. Typical setup (on a RAC node) is using a HBA PCI card that runs fibre connections into a SAN switch. You can also use Infiniband (IB) as the I/O layer (as Oracle's Exadata database machine does). In this case the servers will use HCA PCI cards, run IB cables into the switch, and so will the storage array run an IB cable into the switch.
--how we set up network (private & virtual IP) and how can check working of NIC's.Depends on the achitecture choses as Interconnect. Typical choices are GigE or Infiniband (IB). Oracle's Exadata database machine (RAC) uses IB as already mentioned. (and is also our preferred Interconnect technology)
With IB you would use the OFED driver stack and have a range of ib.. commands available. These can be used to configure IP over IB (IPoIB) for use as an IP-based Interconnect, bonding of NICs, check a port's status, and so on.
--and other required things.As both Daniel and Hans indicated.. you are asking quite complex questions that require a manual (if not several) to be written in response. So best to refer to the manuals and OTN material available.
Also, if you and your company are serious about using RAC, then you should make use of Oracle's RAC Assurance group to assist you. They will provide you with starter kit information for the o/s selected. They will check every single configuration parameter afterwards and deliver a comprehensive report on what's wrong, what works and what doesn't. With recommended changes that need to be done.
