Oracle RAC on Sun server.

Hello Oracle RAC gurus,
I have below questions, I would highly appreciate if anyone can answer these.
1) Is it must to have identical server model and configuartion for Oracle RAC?
2) I have Sun Fire 280R machine with Sun solaris 10. Can I install Oracle RAC on this
using Oracle VMWare?
3) Please let me know below scenario is possible or not,
If I have Oracle Databases(single instances) are running on my Sun server box, can I
use this machine as primary node for Oracle RAC? If this is not possible then
can I use as secondary node?
Thanks gurus.

For 1: NO, the hardware does not need to be exactly the same. The nodes can be different models, with different CPU speed and different RAM sizes. The only consideration is that they must be the same O/S. This is a hardware vendor issue. They determine which configurations they are willing to support.
For 2: RAC is currently not supported in Oracle VM.
For 3: YES, at first glance you can do this. Note that the RAC database requires a cluster database home. Thus, you would need to install a cluster database home in addition to the Single Instance database home(s). However, this answer does not consider whether or not your node would be capable of hosting another database instance in regards to performance.
Thanks.

Is it possible to install Oracle RAC (11gR2)on server having just one NIC ?

Hi all,
Please let me know if it is possible to install Oracle RAC (11gR2) on server having just one NIC card on linux (RHEL5.8).
by creating a virtual NIC like the real ethernet is etho and we are creating eht0:1 as virtual NIC, and i want to use this as eth1, so please suggest me if this is the workaround for my issue or not.... if not please suggest me the best way to install RAC on physical linux box running with one NIC card.
Thanks

ORACLE_HOME in Oracle RAC 11g (Windows Server 2008)

Hello,
I've got two (2) nodes in an Oracle RAC 11g in Windows Server 2008. Oracle software is installed in C:\app.
I realized that it's not been set ORACLE_HOME path. In System Properties-> Advanced -> Environment Variables, I see that ORACLE_HOME is empty.
- Which path would be the ORACLE_HOME: C:\app\bd\product\11.2.0\dbhome_1
- Do you have to setup the same in both nodes?
Thanks

I realized that it's not been set ORACLE_HOME path. In System Properties-> Advanced -> Environment Variables, I see that ORACLE_HOME is empty.its normal behaviour
- Which path would be the ORACLE_HOME: C:\app\bd\product\11.2.0\dbhome_1if you installed that location, yes
- Do you have to setup the same in both nodes?actually, you dont HAVE TO, its not needed at all

Does oracle clusterware and oracle RAC require sun cluster

Hi,
I have to setup oracle RAC on solaris 10 SPARC. so is it necessary to install sun cluster 3.2, QFS file system on solaris
I have 2 sun sparc servers with solaris 10 installed on it and shared LUN setup(SAN disk RAID 5 partitions)
Have to have 2 node setup for RAC load balancing.
Regards
Prakash

Hi Prakash,
very interesting point:
As per oracle clusterware documents the cluster manager support is only for windows and linux.
In case of solaris SPARC will the cluster manager get configured ???
The term "Cluster Manager" refers to a "cluster manager" that Oracle used in 9i times and this one was indeed only available on Linux / Windows.
Therefore, let me, please, ask you something: Which version of Oracle RAC do you plan to use?
Because for 9i RAC, you would need Sun or Veritas Cluster on Solaris. The answers given here that Sun Cluster would not be required assume 10g RAC or higher.
Now, you might see other dependencies which can be resolved by Sun Cluster. I cannot comment on those.
For the RAW setup: having RAW disks (not raw logical volumes) will be fine without Veritas and ASM on top.
Hope that helps. Thanks,
Markus

Veritas required for Oracle RAC on Sun Cluster v3?

Hi,
We are planning a 2 node Oracle 9i RAC cluster on Sun Cluster 3.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with LUNs etc, then why do we need to have Veritas Volume Manager (VxVM) if all the LUNS are configured at a hardware level?
2)
Do we need to have VxFS? All our Oracle database files will be on raw partitions.
Thanks,
Steve

> We are planning a 2 node Oracle 9i RAC cluster on Sun
Cluster 3.Good. This is a popular configuration.
Can you please explain these 2 questions?
1)
If we have a hardware disk array RAID controller with
LUNs etc, then why do we need to have Veritas Volume
Manager (VxVM) if all the LUNS are configured at a
hardware level?VxVM is not required to run RAC. VxVM has an option (separately
licensable) which is specifically designed for OPS/RAC. But if
you have a highly reliable, multi-pathed, hardware RAID platform,
you are not required to have VxVM.
2)
Do we need to have VxFS? All our Oracle database
files will be on raw partitions.No.
IMHO, simplify is a good philosophy. Adding more software
and layers into a highly available design will tend to reduce
the availability. So, if you are going for maximum availabiliity,
you will want to avoid over-complicating the design. KISS.
In the case of RAC, or Oracle in general, many people do use
raw and Oracle has the ability to manage data in raw devices
pretty well. Oracle 10g further improves along these lines.
A tenet in the design of highly available systems is to keep
the data management as close to the application as possible.
Oracle, and especially 10g, are following this tenet. The only
danger here is that they could try to get too clever, and end up
following policies which are suboptimal as the underlying
technologies change. But even in this case, the policy is
coming from the application rather than the supporting platform.

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.

Oracle RAC binaries on vxfs shared file system

Hi,
Is it possible to install oracle binaries on vxfs cluster file system for oracle RAC under sun cluster? Because as I know we can not use vxfs cluster file system for our oracle datafiles.
TIA

The above post is incorrect. You can have a cluster (global) file system using VxVM and VxFS. You do not need to have VxVM/CVM for this. A cluster file system using VxVM+VxFS can be used for Oracle binaries but cannot be used for Oracle RAC data files where they are updated from both nodes simultaneously.
If further clarification is needed, please post.

Oracle RAC performance

Hello all,
I have a 3 node oracle RAC. Each server has 2 intel quad core processors. I was asked to extend the RAC to 5 nodes to increase the processing power. I was told that Intel 6 core processors are in the market. So I was looking at the following options and need your input/expertise or suggestions on the following options.
Option 1: Add 2 more nodes with 2 quad core processors to the existing 3 node RAC. so total cores available to process the load will be 40 cores.
Option 2: completely replace all the above 5 nodes(in option 1) with 4 nodes - each with 2 * 6 core processors. total cores available are 48 core.
option 2 will give have 1 less server to maintain.
will the performance on option 2 be better than option 1? Any there any white papers or documentation to help me take a decision as to which option i should go?
Thanks in advance.

hi
I would also first try to tune the database. However it demands some professional skills. There are many areas of tuning.
For example, if your storage subsystem runs slowly (often a bottleneck), then you will not benefit from and node's scaling!
Upgrading hardware is the last thing to do, as it is costly.
If you have a budget, then run for it, buy new "toys", why not, but make sure you hit the performance issue lest you spent money with no improvement...brr
So start with storage, if disks are old e.g. 10k RPM replace them with new 15k RPM, or SSD even.
Run AWR, see "Top 5 events", find the slowest subsystem, if this is I/O then invest in disks, if CPU then CPU, etc.
Replacing old hardware (scale-up) have this benefit, that you don't have to buy all components and install all software from the scratch (OS, add nodes).
Also, however it is not forbidden, but it's been said by Oracle, nodes should have similar performance.
Next thing is that adding more than 3 nodes to the RAC cluster , probably will not improve the overall performance in a linear way, and is more expensive.
My suggestion is to scale-up after inspecting and finding the bottleneck of the cluster performance.
Hope this helps,

How to configure sun application server 8.2 for Oracle RAC 10g

Hello,
We have numerous boxes running the sun platform application server 8.2 and 2 boxes running enterprise version 8.2 all connecting to a 4 node Oracle RAC 10 G release 2 database. We have the system up and working. The application servers are connecting just fine to the database and the apps don't have any problems querying, inserting, etc. However, when we try to do failover testing of situations when a node or nodes of the Oracle RAC database goes down the application server does not gain new valid connections. Our configuration is this, OracleDataSource for the data source, table validation turned on with a valid table, ONS configuration set in properties, connectionCache enabled, and fastconnectionfailover enabled as well in the properties. We have that long oracle rac url with load balancing turned on set fot the database URL. We have the checkbox checked to fail all connections on any failure. ONS is configured properly within the database because we have a java application that runs outside of the application server that uses all the same settings described above (only set manually in our code for the OracleDataSource). This application works seemlessly when DB nodes are shutdown. We can shutdown all but one node and it's still humming along without skipping a beat. Start up one of the others, kill the last node, it still hums along nicely without skipping a beat. We'd really like to get the applications running in the application server to work the same way. Any help would be greatly appreciated. We've tried all the combinations that we can think of with configuration settings in the application server and it never works. Am tempted to rip out the database connection pool from inside the application server and configure it manually in the code but we are using entity beans and this is the much easier approach, if it will work. It's down to the point of does sun application server actually work with oracle RAC for connection failovers.

Hi,
We are also facing similar execption. Here is the error, we are getting, when a node is failed on RAC.

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.

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:,

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

DO I need SFRAC for Oracle 10g RAC on Sun Solaris

My platform is SUN Solaris 10 64 bit on v490 server. On the backend side, we are using EMC CX500 storage. We will use Veritas File system and Veritas CFS.
I would like to ask, Do I must need SFRAC to configure Oracle 10g RAC or Can I just use only Oracle CRS. I do not want to use ASM.
Please advise
Thanks,
Sam..

The VCFS usually requires a Veritas Cluster, thus you would have to use the product combination that is bundled as SFRAC as mentioned before. Metalink in addition says:
10 10gR2 64-bit Veritas Storage Foundation for Oracle RAC 5.0 Certified
There is one exception to this rule: Linux.
Veritas and Oracle support a standalone version of the Veritas Cluster Files System (and only this component) on Linux. This does not hold true for Solaris.
Concluding, if you want to use the VCFS you would need to get a VCS, which then basically means using SFRAC.
However, in this case, as mentioned before, you would not need ASM.

Oracle 9i RAC on Sun Solaris 5.10/64 bit version.Is that supported ?

I want to install Oracle 9i RAC on Sun Solaris 10 64 bit. Is that officially supported ?
I dont this combination on metalink certify matrix

I know we dont get support from oracle.But, you initially mentioned that you couldn't find the required information on metalink, therefore I provided that information, which I thought you were looking for.
Is anybody still using this combination ? Does it work ? yes, we are using it and it has been working fine for over 4 years...of course we patched it to the latest - 9.2.0.8 to be on the supported release/patch.

Sun Fire V490 x 2 servers with Oracle RAC facing Split brain problem

Hi all,
I have Sun Fire V490 x 2 servers with Oracle RAC and they faced a Split brain problem. One of the node's database instance has gone down, The DBA claims it is due to network problem, but as such the networks are OK. We use the on board CE1 interface for Cluster interconnect and CE0 as the public interface.
Did anybody face this kind of a problem? Could this be a hardware/OS patch problem?
I had kept a continuous ping for 24 hours after this happened last time and the output shows no packet loss
Many thanks in advance.
Ushas Symon

In order to diagnose this properly, you'll need to provide too much detail and far too many log files for a generic discussion forum to handle.
Use your service contract and open a support case.
Because a cluster environment is involved you'll likely end up talking to the cluster support staff.
They can analyze hardware and software errors as well as review whether you configured the systems in a supportable fashion.
Be prepared to make a direct connection to each system and gather data using such as by using the Explorer tool. The technical support staff will tell you what they will actually need.
