10gR2 RAC on Dell/EMC AX150

I have a Fibre Channel Array say Dell/EMC AX150.
I need to understand the following
a. The Dell/EMC AX150 comes with QLOGIC QLE220 FC4 Single Channel HBA
will I need "QLOGIC QLE220 FC4 Single Channel Two HBAs" for a 2-node RAC
Will I need HBA for host servers too?
b. Can i do a 2-node RAC without the Fibre Channel Switch
Since
http://www.oracle.com/technology/products/database/clustering/certify/tech_generic_linux_new.html
says for the storage section
"Switch required for greater than two nodes"
c. Can i connect the HBA on the storage array to NIC1 of node1
and HBA on the storage array to NIC2 of node2
using the Fibre Channel Cables provided with the storage box
Thanks
Cyril

Please let me know if you have managed to put in the production what you describe below. We are pretty much in the same situation right now, looking for a cost-efficient disk array solution for Oracle RAC. Based on the information I found on the Internet so far:
"a" - you need those HBAs for the servers, which will be running Oracle RAC and accessing the disk array - so if you plan to have twp nodes in RAC, you do need two cards
"b" - the answer seems to be "yes", but it looks like you may need "cross-over" fiber channels in this case (the Re: can fiber channel be used for connect server to a storage in two nodes RAC post - but looks like you've already seen that one and even replied :-) )
"c" - I think you put HBAs into your servers, and then connect them with cables to your disk array (normally via switch - but see above).

Oracle 10gR2 RAC / Dataguard on Linux Redhat 4.2 X86_64 and ASM / OCFS2

Hi All,
Well don't know if this is bleeding edge or not, but wanted to know if anybody has a system running the following setup and if there are any issues like some components are not certified on 64 bit (e.g is OCFS2)
We are in process of building a system with
Oracle RAC on 10gR2 on a 64 bit Linux OS 4.2 (2.6.9-22.ELsmp)
The system has a EMC CX500 and we are going to use ASM for the datafiles and OCFS2 for the Voting Disk and OCR.
We are also going to have a single (no RAC) Physical Dataguard instance at another site also using ASM.
We have seen that the OEM Grid Controller and agents are not supplied on x86_64
so we can't use it in a 64bit environment. (are we correct)
Anybody with suggested alternatives with the kit we have or a strong suggestion that 32 bit for RAC and Dataguard are best
Thanks in advance
John

I have a similar configuration, 3 nodes of SunFire X4100 (dual opteron), on RedHat 4 ES Update 2 using Dell/EMC CX300.
I am using OCFS2 for data and voting disks.
We had a couple of freeze-up (total node lockup) and I could not figure out what was wrong (this happens randomly).
Anybody have any idea where should I look for possible reasons?

10gR2 RAC on Solaris 10

Hi,
I am looking for "step by step install & configure" guide to setup 10gr2 RAC on Solaris 10.
I got the following Doc "ID: Note:317257.1" from metalink. Looks like I need to configure Solaris 10 containers and Solaris Zones for 10g RAC.
Is there another way to setup 10gr2 RAC on Solaris 10 without using the Solaris 10 containers just like (Solaris 9 or plain OS)?
Any help would be appreciated.
R-

Thanks for all your inputs. I finally got 10g RAC installed and running.
I learned that there is no way to install Oracle software and configure ASM during installation. I had to install “Software Only” then configure ASM at the later time, then that will work.
Good luck to you all.

Solaris 10 + Oracle 10gR2 RAC question

Hello everyone
Has anyone come across the case where the CRS services of Oracle cause
the public interface to get turned off and then restored at random
time intervals? To elaborate, we have a 2 node cluster database.
Solaris 10, Oracle 10gR2 RAC with patch 10.2.0.3 applied. No SUN
clustering is involved. When the cluster software is down (nodeapps,
asm, database instances all down) /var/adm/messages show nothing. When
we start nodeapps on the 2 nodes(thus initiating some form of
communication between the nodes), at random time intervals we get
"interface ce0 turned off and interface ce0 restored" in /var/adm/
messages. When we check the status of the RAC, we see that one node's
vip has been assigned to the other. This on/off behaviour of the NIC
can be eliminated only if we continuously PING it from a another
client in the network.
As a matter of fact, the RAC and the RDBMS work perfectly when we keep
pinging the 2 nodes from an other client on the network. We even
managed to run a long batch job, distributed on cluster managed
services on the 2 instances, and it completed after 9 hours without
any problems.
Does anyone have a hint on this behaviour? Is there some sort of
timeout for the network cards? Some power saving features? Googling
around I came across the new Containers feature available on Solaris
10. Is there a way that I can verify that either RAC or the RDBMS is
running in "container" mode ( since the solaris and Oracle
installation was not performed by me)? Any other ideas?
Thank you for reading

Im an Oracle guy - not the SA type -
But on ours - the SA configured this cluster incorrectly. We use veritas. instead of making ipmp groups for the interfaces - he built the cluster according to veritas docs. That is - he has two publics - on difference interfaces and different privates on different interfaces. oracle can only two interfaces - no matter if its a ipmp group or a device name. one is used for private- the other is used for public - So sure the veritas cluster filesystems will survive - but the Oracle Cluster will not - nodes will reboot -
Is your system set up incorrectly as i described above? if it is - a quick test would be - turn down the other interfaces - and only leave the two interfaces you mention above up that you configured for Oracle CRS
This other sharp sa was able to go through the arp table and see duplicate IPs - and the routing was attempted via an interface that oracle doesnt see. You can not define two different interfaces public - and two different interfaces for private -

Can we have separate 10gR2 RAC CRS and 11gR2 RAC CRS homes on same Unix s

We'd like to test the upgrade of our 10gR2 RAC databases to 11gR2 RAC.
We have six databases on the same server and want to install a separate 11g RAC stack (11g CRS, 11g ASM, 11g RDBMS) and upgrade each 10g database from 10g RAC stack on same server (10g CRS, 10g ASM, 10g RDBMS) . Is it ok to have 10g CRS home and 11g CRS home same server? If not, how best to upgrade without buying more hardware?
Thanks in advance,
Lou

In more detail, the main issue/question is whether there can be 2 Oracle CRS homes on the same server i.e. separate 10gR2 and 11gR2 CRS homes residing on the same server for the purposes of (gradually) upgrading all Oracle RDBMS homes from 10g RAC to 11g RAC.
Can there be? What would be the implications for the OCR and voting disk? In our case 10g CRS has OCR and Voting Disk on raw devices. In 11gR2, these would need to be migrated/upgraded/stored in ASM, right?
We have 6 10g rdbms homes in addition to the one 10g CRS home and one 10g ASM home. To upgrade can we
- Install 11gR2 CRS in a separate home (this would now include ASM as well)
- Install 11gR2 RDBMS home
- Upgrade one of the 6 10g databases while leaving the others untouched as 10g databases in the separate 10g CRS, 10g ASM stack?
Any ideas, pointers greatly appreciated.
Thanks,
Lou

10gR2 RAC installation: OUI forgets to create directory 'crs/auth' (BUG)

Hi,
We've got a new installed 10gR2 RAC cluster (2 nodes) on AIX. But there were several errors during startup of CRS (Cluster Ready Services).
The error log shows, that it couldn't write a special file (I guess a lock file).
So I just created the missing directory 'crs/auth' and anything works fine now.
This post is just for those who are looking for a solution for their non-working crs daemon. No need to answer.
But I suppose Oracle should log it as an installation bug, because the Universal Installer does not create this directory and so the CRS can not work.
Best regards
Sven

it looks like i hit a bug in crs 11.1.0.6 -> bug 6782573

Guidelines for SGA and PGA tuning for 10gR2 RAC and ASM ?

I am looking for tuning information on SGA and PGA tuning for Oracle 10g (10.2) RAC and ASM for a 4TB OLTP and DSS mixed environment on Solaris 10 platform.

We are running Solaris 10 SPARC 64 bit with Oracle 10gR2 RAC Enterprise Edition and ASM on Sun servers with 32GB of RAM for memory for a 4TB OLTP database.
It is in design phase so I do not have an existing AWR or Statspack report yet. Is there a best practices guideline on how to size parameters for the SGA (ie: shared_pool_size, etc) and PGA for this environment from Oracle?

Oracle 10gR2 RAC - ASM question

Hi
I have a question regarding the ASM storage. Let says I have a system here running Oracle 10gR2 RAC and would like to add a new/extend the current DATA disk group with more disk space. How do I do that? will it affect the existing data stored inside there?

So to add a little more to the discussion. Let's say your storage administrator presents you a LUN and is nice enough to add a partition of say 7G. (/dev/sdo1).
Now you need to take /dev/sdo1 stamp it and alter your storage group.
For illustration purposes I shall use rac1 and rac2 as my dual instance RAC and add to the asm group ARCH.
As root on rac1
/etc/init.d/oracleasm createdisk ARCH2 /dev/sdo1
then run
/etc/init.d/oracleasm listdisks
to make sure ARCH2 shows up.
On rac2 you run
/etc/init.d/oracleasm listdisks
You don't see ARCH2 so then run
/etc/init.d/oracleasm scandisks
then
/etc/init.d/oracleasm listdisks
Now you should see ARCH2
Ok the asm stamps are in sync now.
Back to rac1
su - oracle
set ORACLE_SID to asm instance and use sqlplus
sqlplus / as sysasm
If you query V$ASM_DISK you will see your disk with a header_status of PROVISIONED
that's good ...
NOw while still in sqlplus
Let's bump up the asm_power_limit so rebalancing runs faster
alter system set asm_power_limit=5 scope=both ;
If your asm instance are sharing the same spfile you only need do this on one instance; otherwise run the command both on all asm instances.
Lastly
ALTER DISKGROUP ARCH ADD DISK 'ORCL:ARCH2' ;
Now you can query V$ASM_OPERATION and watch ASM do it's magic of rebalancing.
That's it. All done while the DB is up and running.
How does that work for you?

HI!
In my practise we have hardware to move 10g -> 11g.
We upgrade our DB's -> install Grid 11g on new server, move DB 10g, Upgrade 10g -> 11g.

10gR2 RAC

Hi All,
Iam preparing a document to be presented to the management on below topics. Any help from your end is highly appreciated.
1. 10gR2 RAC on Windows (yes, windows - no unix flavour)
Topics that are being covered
- Best storage filesystem
- Special Considerations for Windows
2. Is there a possibility of logically splitting ERP modules between two instances, like, AR, AP related connections to go to Instance 1 and GL, FA connections to go to Instance 2.
Iam aware that the connection split can be done at the mid-tier level, but is it possible on the instance level.
Much appreciate your time.
cheers,
Ram.

I think both topics are covered right here on OTN - in the documentation library. This is the configuration and installation guide:
http://download-uk.oracle.com/docs/cd/B19306_01/install.102/b14207/toc.htm
Topic 2 can be achieved through the SERVICES concept, that's also covered in the document above.
Difficult is the question, what's the BEST storage filesystem. You will get different answers from different vendors, but you should go on the Oracle side for ASM.

10gR2 Rac deployment.

Hi All;
I have to deploy Oracle 10gR2 Rac on SAN .U all ppl know that for rac deployment oracle use Oracle Cluster file system deploying OCFS to a shared disk device like a SAN allows database files to be shared between multiple instances.Another disk management system new to Oracle 10g is named Automatic Storage Management (ASM).I want to know that can we use ASM on SAN.At this time I dont want to use OCFS on SAN.Plz reply me ASAP...
Thanx in advance.
Asif

Yes, this is exactly what ASM is designed to accomplish.
Read up: http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/storeman.htm#sthref1624
"Automatic Storage Management (ASM) is an integrated file system and volume manager expressly built for Oracle database files. ASM provides the performance of raw I/O with the easy management of a file system. It simplifies database administration by eliminating the need for you to directly manage potentially thousands of Oracle database files. It does this by enabling you to divide all available storage into disk groups. You manage a small set of disk groups and ASM automates the placement of the database files within those disk groups."
"In a clustered environment, each node runs an ASM instance, and the ASM instances communicate with each other on a peer-to-peer basis. This is true for both Real Application Clusters (RAC) environments, and non-RAC clustered environments where multiple single-instance databases across multiple nodes share a clustered pool of storage that is managed by ASM. If a node is part of a Real Application Clusters (RAC) system, the peer-to-peer communications service is already installed on that server. If the node is part of a cluster where RAC is not installed, the Oracle Clusterware, Cluster Ready Services (CRS), must be installed on that node.
An ASM instance on a node in a cluster can manage storage simultaneously for one or more RAC database instances and one or more single instance databases."

Management Agent service not created with 10gR2 RAC DB install on Win2003?

Our 10gR2 RAC installation on Win2003 platform didn't create management agent service. After installing and setting up current release of OEM with Grid Control (10.1) and installing Management Agent from 10.1 OEM distribution (install additional management agents option), agent service is up and running. However, there is one small problem:
All target configuration xml files are created under 10.2 Oracle home, and agent running from 10.1 home does not see them - which means database, listener, etc are not registered in OEM.
Is this a known problem, and is there solution for it?
thanks,
Dejan Bogojevic

10gR2 RAC On Solaris9

is 10gR2 RAC On Solaris9 is certified by oracle? If i install it on Solaris9, what problems i could face? & what would be the advantage of installing this on Solaris10?

You can check the matrix certification without metalink access :
http://www.oracle.com/technology/support/metalink/index.html
A certified config means first that works (tested by Oracle Corp.), then Oracle support team is allowed to answer to your issues, lastly and not at least, Oracle may build out patch/patchset if required.
