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.

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?

The best option to create a shared storage for Oracle 11gR2 RAC in OEL 5?

Hello,
Could you please tell me the best option to create a shared storage for Oracle 11gR2 RAC in Oracel Enterprise Linux 5? in production environment? And could you help to create shared storage? Because there is no additional step in Oracle installation guide. There are steps for only asm disk creation.
Thank you.

Here are names of partitions and permissions. Partitions which have 146 GB, 438 GB, 438 GB of capacity are my storage. Two of three disks which are 438 GB were configured as RAID 5 and remaining disk was configured as RAID 0. My storage is Dell MD 3000i and connected to nodes through ethernet.

Installation Guide needed for Oracle RAC 10G R2 Linux x86-64

Hello All,
Can someone point me to the Oracle documentation on installing Oracle RAC 10G R2 (10.2.1.0) for Linux x86-64?
Seem unable to find the required doc.
I greatly appreciate your help!

Problem of using OCFS2 as shared storage to install RAC 10g on VMware

Hi, all
I am installing a RAC 10g cluster with two linux nodes on VMware. I created a shared 5G disk for the two nodes as shared storage partition. By using OCFS2 tools, i formatted this shared storage partition and successfully auto mounted it on both nodes.
Before installing, i use the command "runcluvfy.sh stage -pre crsinst -n node1,node2" to determine the installation prerequisites. Everything is ok except an error "Could not find a suitable set of interfaces for VIPs.". By searching the web, i found this error could be safely ignored.
The OCFS2 works well on both nodes, i formatted the shared partition as ocfs2 file system and configure o2bc to auto start ocfs service. I mounted the shared disk on both nodes at /ocfs directory. By adding an entry into both nodes' /etc/fstab, this partition can be auto mounted at system boots. I could access files in shared partition on both nodes.
My problem is that, when installing clusterware, at the stage "Specify Oracle Cluster Registry", I enter "/ocfs/OCRFILE" for Specify OCR Location and "/ocfs/OCRFILE_Mirror" for Specify OCR Mirror Location. But got an error as following:
----- Error Message ----
The location /ocfs/OCRFILE, entered for the Oracle Cluster Registry(OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system that is visible by the same name on all nodes of the cluster.
------ Error Message ---
I don't know why the OUI can't recognize /ocfs as shared partition. On both nodes, using command "mounted.ocfs2 -f", i can get the result:
Device FS Nodes
/dev/sdb1 ocfs2 node1, node2
What's the possible wrong? Any help is appreciated!
Addition information:
1) uname -r
2.6.9-42.0.0.0.1.EL
2) Permission of shared partition
$ls -ld /ocfs/
drwxrwxr-x 6 oracle dba 4096 Aug 3 18:22 /ocfs/

Hello
I am not sure how far this following solution is relevant to your problem (regardless when it was originally posted - may help someone who is reading this thread), here is what I faced and here is how I fixed it:
I was setting up RAC using VMWare. I prepared rac1 [installed OS, configured disks, users, etc] and the made a copy of it as rac2. So far so good. When, as per the guide I was following for RAC configuration, I started OCFS2 configuration, faced the following error on RAC2 when I tried to mount the /dev/adb1:
===================================================
[Root @ *rac2* ~] # mount - t ocfs2 - o datavolume, nointr / dev / sdb1 / ocfs
ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid
mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted" mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted"
===================================================
After a lot of "googling around", I finally bumped into a page, the kind person who posted the solution said [in my words below and more detailed ]:
o shutdown both rac1 and rac2
o in VMWare, "edit virtual machine settings" for rac1
o remove the disk [make sure you drop the correct one]
o recreate it and select *"allocate all disk space now"* [with same name and in the same directory where it was before]
o start rac1 and login as *"root"* and *"fdisk /dev/sdb"* [or whichever is/was your disk where you r installing ocfs2]
Once done, repeat the steps for configuring OCFS2. I was successfully able to mount the disk on both machines.
All this problem was apparently caused by not choosing "allocate all disk space now" option while creating the disk to be used for OCFS2.
If you still have any questions or problem, email me at [email protected] and I'll try to get back to you at my earliest.
Good luck!

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.

Solaris 10 Installation for Oracle RAC 10g Rel2

Hello,
I have bought Enterprise 4000 and 250 in order to install and explore Oracle 10g Rel2 RAC.
In this regard I need some guide lines for
1. Installinig Solaris 10
2. Should I use ASM or other other volume manager?
If anybody can give me a starting document, it will be great.
Thanks,
Javed

I'm assuming you mean running RAC with or without Sun Cluster? If so, the answer is that there would almost no difference in most cases. The only case I can think of would be if you had a sub-optimal interconnect without Sun Cluster where Sun Cluster's clprivnet would have given you striping and availability for free.
I am currently working on a Blueprint that describes the important differences between the two configurations (with and without SC). They can broadly be summarised as:
Sun Cluster gives you:
* Better data integrity protection
* Faster, more reliable node failure detection
* Makes your name space homogeneous, simplifying installation and device management (DID structure), so no need for messy symbolic links
* Gives you a highly available, striped cluster interconnect for the Cache Fusion traffic. (No need for tricky IPMP or link aggregation configurations.)
* Allows you to use volume managers link Solaris Volume Manager or VxVM
* Provides support for shared QFS as a file system for all Oracle objects, data includes (while still allowing ASM)
* A substantial collection of Sun written and supported agents to manage other applications you might also have on your cluster, e.g. NFS, SAP, Apache, etc, etc.
Hope that helps,
Tim

Shared Storage for RAC

Dear All,
what is the best options for shared storage system for Oracle RAC 10g R2 on windows operating system.
How to share disk in windows so that it can be available in all RAC nodes in Dynamic mode.
Need help from people who have configured RAC on windows operating system and have used shared disk option.
Regards,
Imran

In production, the only realistic options are to turn to certified SAN or NAS vendors.
The issue is simplel - even though many types of shared storage allows you to have multiple machines connected to the same disk, certified shared storage allows these machines to write to the same disk sector and block. Most storage solutions have built-in protection to stop that from happening.
For a small shop, I certainly recommend NetApp NAS.

Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0

Hello,
Maybe you can help me (new on RMAN backup) in doing this.
I have configured a single Oracle 10g database to have backup with RMAN with following steps:
1. $ mkdir $ORACLE_BASE/rman_scripts
2. $ mkdir $ORACLE_BASE/logs
3. $ mkdir $ORACLE_BASE/tracking
4. $ mkdir $ORACLE_BASE/c_backup
5. $ sqlplus sys/<password> as sysdba
6. SQL> alter system set db_recovery_file_dest_size = 50G scope=both;
7. SQL> alter system set db_recovery_file_dest='${ ORACLE_BASE}/flash_recovery_ area' scope=both;
8. SQL> alter system set log_archive_dest_10='location= use_db_recovery_file_dest';
9. SQL> shutdown immediate
10. SQL> startup nomount
11. SQL> alter database archivelog;
12. SQL> alter database open;
13. SQL> alter database enable block change tracking using file '${ORACLE_BASE}/tracking/rman_ change_track.f';
14. $ rman target /
15. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK

16. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
17. RMAN> CONFIGURE BACKUP OPTIMIZATION ON;
18. RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
19. RMAN> exit
I need to configure incremental backup with RMAN on a two node Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0 installation.
We also use ASM to store database files, and have Oracle software installed on separate file systems (two Oracle roots for Node1 and Node2).
I have following questions:
1) where to put Flash Recovery Area (FRA)?
I saw recommendations to put FRA on the ASM, is this the best way to do it?
2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
3) Is it possible/recommended to run RMAN from Node1 only?
Below is the script used to run RMAN on the normal Oracle database (without RAC) which I need to change :
=============================================================================================
2.0 Oracle backup script: /opt/app/oracle/rman_scripts/backup.sh
Use this for daily backups, possiblly as a cron job.
Once a week run this: /opt/app/oracle/rman_scripts/backup.sh FULL
All other days of the week: /opt/app/oracle/rman_scripts/backup.sh INCREMENTAL
Note: You may have to change ORACLE_SID, ORACLE_BASE below to match your database.
=============================================================================================
#!/usr/bin/ksh
ORACLE_SID=orcl
ORACLE_BASE=/opt/app/oracle
ORACLE_HOME=${ORACLE_BASE}/product/10.2.0/db_1
PATH=${ORACLE_HOME}/bin:/usr/bin
LOGDIR=${ORACLE_BASE}/logs
LOGFILE=${LOGDIR}/rman.log
if [[ $# < 1 ]]
then

exit;
fi
BACKUPTYPE=${1}
full='FULL'
incremental='INCREMENTAL'
if [[ $BACKUPTYPE == $full ]]
then
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup database;
SQL 'alter system archive log current';
backup archivelog all;

Hi [email protected],
Q1) where to put Flash Recovery Area (FRA)?
A1) With RAC: on the shared storage
I saw recommendations to put FRA on the ASM, is this the best way to do it?
If you want your backups to be available for both nodes you have to use shared storage or tape using an mml library.
So if you want to use the FRA for rman backups and the database is on ASM just make ASM the standard for the FRA as well.
Q2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
A2) Than you cannot recover in case Node1 is down. Best would be to send your storage admin to a training course so he can manage the clustered raw devices needed for ASM.
Q3) Is it possible/recommended to run RMAN from Node1 only?

Recommendations - Oracle RAC 10g on Solaris 10 Containers Logical/Local..

Dear Oracle Experts et all
I have a couple of questions for Oracle 10g RAC implementation on Solaris and seek your advice. we are attempting to implement oracle 10g RAC on Solaris OS and SPARC Platform.
1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? I was assuming that Oracle will always link it self with OS binaries and Libraries while S/W installation and hence will need an OS image/Root Disk over which it could go. However, in containers, I assume we have a single solaris installation and configuration which will thus be shared to the containers which will be further configured in it. In such situations how does Oracle instalation proceed? Do I need to look at a scenario where, the global Container/Zone will have Oracle install and this image be shared across to zones/containers accordingly? If it is so, what all filesystems from OS will need to be shared across to these zones/containers?
Additionally, even if this approach is supported, is it a recommended approach? I am unsure about the stability and functionality of Oracle in such cases and am not able to completly conceptualize. However, I assume there could be certain items which needs to be approprietly taken care off. It will help if you could share observations from your experiences.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?
Our requirement is to have the above mentioned multiple Oracle installations spread across two (2) seperate H/W platforms,say Node A and Node B, and configure our Cluster Solution to behave as active-passive across Node A and Node B. In other words, I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. I will configure one database each for each of these Oracle S/W installation (with an idea not to have Clusterware between clustering solution VRTS/SunCluster and Oracle installation, if it works). Now I will run 3 databases thus on each of these nodes. If any downtime happens on any one of the nodes, say Node A, I will fail all oracle databases and S/W accordingly to the alternate available node, Node B in this case, using native clustering solution and I will want the database to behave as it was behaving earlier, on Node A. I am not sure though if I will be able to bring the database up on Node B when resources in OS perspective are failed over.
we want to use Oracle 10g RAC Release 2 EE on Solaris 10 OS latest/one before the latest release.
Please share your thoughts.

1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? My understanding is that RAC in a Zone (Container) is not supported by Oracle, and will not work anyway. Regardless of installation, RAC needs to do cluster level stuff about the cluster configuration, changing network addresses dynamically, and sending guaranteed messages over the cluster interconnect. None of this stuff can be done in a Local Zone in Solaris, because Local Zones have fewer permissions that the Global Zone. This is part of the design of Solaris Zones, and nothing to do with how Oracle RAC itself works on them.
This is all down to the security model of Zones, and Local Zones lack the ability to do certain things, to stop them reconfiguring themselves and impacting other Zones. Hence RAC cannot do dynamic cluster reconfiguration in a Local Zone, such as changing virtual network addresses when a node fails.
My understanding is that RAC just cannot work in a Local Zone. This was certainly true 5 years ago (mid 2005), and was a result of the inherent design and implementation of Zones in Solaris. Things may have changed, so check the Solaris documentation, and check if Oracle RAC is supported in Local Zones. However, as I said, this limitation was inherent in the design of Zones, so I do not see how Sun could possibly have changed it so that RAC would work in a Local Zone.
To me, your only option is the Global Zone. Which pretty much destroys the argument for having Zones on a Solaris system, unless you can host other non-Oracle application on the other Zones.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?I am not sure the term 'native' is correct. All 'Cluster' software is low level, and has components that run within the operating system. Whether this is Sun Cluster, Veritas Cluster Server, or Oracle Clusterware. They are all as 'native' to Solaris as each other. They all perform the same function for Oracle RAC around Cluster management - which nodes are members of the cluster, heartbeats between nodes, reliable fast message delivery, etc.
You only need one piece of Cluster software. So pick one and use it. If you use the Sun or Veritas cluster products, then you do not need the Oracle Clusterware software. But I would use it, because it is free (included with RAC), is from Oracle themselves and so guaranteed to work, is fully supported, and is one less third party product to deal with. Having an all Oracle software stack makes things simpler and more reliable, as far as I am concerned. You can be sure that Oracle will have fully tested RAC on their own Clusterware, and be able to replicate any issues in their own support environments.
Officially the Sun and Veritas products will work and are supported. But when you get a problem with your Cluster environment, who are you going to call? You really want to avoid "finger pointing" when you have a problem, with each vendor blaming the cause of the problem on another vendor. Using an all Oracle stack is simpler, and ensures Oracle will "own" all your support problems.
Also future upgrades between versions will be simpler, as Oracle will release all their software together, and have tested it together. When using third party Cluster software, you have to wait for all vendors to release new versions of their own software, and then wait again while it is tested against all the different third party software that runs on it. I have heard of customers stuck on old versions of certain cluster products, who cannot upgrade because there are no compatible combinations in the support matrices between the cluster product and Oracle database versions.
I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. As I said before, these 3 Oracle installations will actually all be on the same Global Zone, because RAC will not go into Local Zones.

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.
thanks for the patience

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

I had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps.

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.

Product Oracle Server - Enterprise Edition Product Version 9.2.0.6.0
Platform Linux x86
Platform Version 2.4.21-9.0.1
Database Version 9.2.0.6.0
Affects Platforms Port-Specific
Severity Severe Loss of Service
Status Not a Bug. To Filer
Base Bug N/A
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
