Veritas Cluster failover for oracle

Hi,
I'm performing veritas cluster failover for 2 oracle servers which is not working in one way. I've 2 solaris boxes where veritas cluster is configured for failover. In Box1 I'm running 10g and Box2 9.2 when I failover from Box1 to Box2 is working but the other way is not working I'm using 10g listerner for both the services.
Any help would be appreicated.
Thanks,

Veritas Cluster (SFRAC) and oracle CRS

We have oracle 9i RAC running on Solaris 9 with over veritas cluster.
We want to run 10g RAC on the same same servers which will use the
veritas cluster file system
While trying to install 10g CRS the node selection list doesnt show node
information.Entered information using response file .After the installation
root.sh fails to start CRS.
Is it ok to run 9i and 10g RAC on same servers.

We have a libskgxn2.so in /opt/ORCLcluster/lib directory. But the size of the file is
different from /opt/VRTSvcs/rac/lib/libskgxn2_64.so.1 file
Since we already have 9i rac running, I am not sure if copying the file from
/opt/VRTSvcs/rac/lib directory if it will affect 9i rac.
I went ahead with installation of CRS. I am getting following error while running root.sh
Checking to see if Oracle CRS stack is already configured
Checking to see if any 9i GSD is up

With CRS and veritas running on the same server , will CRS always communicate
across nodes using VCS since we will be using veritas cluster file system
for database.

SC 3.0 file system failover for Oracle 8i/9i

I'm a Oracle DBA for our company. And we have been using shared NFS mounts successfully for the archivelog space on our production 8i 2-node OPS Oracle databases. From each node, both archivelog areas are always available. This is the setup recommended by Oracle for OPS and RAC.
Our SA team is now wanting to change this to a file system failover configuration instead. And I do not find any information from Oracle about it.
The SA request states:
"The current global filesystem configuration on (the OPS production databases) provides poor performance, especially when writing files over 100MB. To prevent an impact to performance on the production servers, we would like to change the configuration ... to use failover filesystems as opposed to the globally available filesystems we are currently using. ... The failover filesystems would be available on only one node at a time, arca on the "A" node and arcb on the "B" node. in the event of a node failure, the remaining node would host both filesystems."
My question is, does anyone have experience with this kind of configuration with 8iOPS or 9iRAC? Are there any issues with the auto-moving of the archivelog space from the failed node over to the remaining node, in particular when the failure occurs during a transaction?
Thanks for your help ...

The problem with your setup of NFS cross mounting a filesystem (which could have been a recommended solution in SC 2.x for instance versus in SC 3.x where you'd want to choose a global filesystem) is the inherent "instability" of using NFS for a portion of your database (whether it's redo or archivelog files).
Before this goes up in flames, let me speak from real world experience.
Having run HA-OPS clusters in the SC 2.x days, we used either private archive log space, or HA archive log space. If you use NFS to cross mount it (either hard, soft or auto), you can run into issues if the machine hosting the NFS share goes out to lunch (either from RPC errors or if the machine goes down unexpectedly due to a panic, etc). At that point, we had only two options : bring the original machine hosting the share back up if possible, or force a reboot of the remaining cluster node to clear the stale NFS mounts so it could resume DB activities. In either case any attempt at failover will fail because you're trying to mount an actual physical filesystem on a stale NFS mount on the surviving node.
We tried to work this out using many different NFS options, we tried to use automount, we tried to use local_mountpoints then automount to the correct home (e.g. /filesystem_local would be the phys, /filesystem would be the NFS mount where the activity occurred) and anytime the node hosting the NFS share went down unexpectedly, you'd have a temporary hang due to the conditions listed above.
If you're implementing SC 3.x, use hasp and global filesystems to accomplish this if you must use a single common archive log area. Isn't it possible to use local/private storage for archive logs or is there a sequence numbering issue if you run private archive logs on both sides - or is sequencing just an issue with redo logs? In either case, if you're using rman, you'd have to back up the redologs and archive log files on both nodes, if memory serves me correctly...

Scripting cluster failover for patching (2008 server not R2)

We have a number of Windows 2008 (not R2) servers running sql. We currectly patch using a third party tool (Shavlik) and would like to automate the process. eg. failover, patch, failback, check status. I started looking at Powershell
but it appears the cluster modules are for 2008R2 and not plain 2008. Anyone have a solution? Thanks.

As noted above, your best option is to upgrade to the latest OS - lots of good reasons to do that anyway. Otherwise, with 2008 you will need to script things with the cluster.exe and wmi commands executed via winrm (if you want to perform them remotely).
You would most likely put as much time, effort, and money into creating something that works in 2008 as it would take to upgrade to the latest Windows Server 2012 R2. And then, by having 2012 R2 in place it prepares you for v.Next which will enable a
rolling upgrade capability within a cluster.

How to manually create a standby db with SAN for hardware cluster failover

Hi all,
The primary db(oracle 9i r2, Sun Solaris) puts its datafile, redo logs, control files in SAN while the pfile, listener and tnsnames files are in its local hardisk. I need to create a standby db(not for dataguard) for hardware cluster failover, where if the primary db fails the hardware cluster will failover to standby db(mounting the datafile, redologs, control files in
SAN to a mount point automatically and start the db services). But I don't know how to create the standby db, I would install the db software first then should I copy the pfile(created from primary db), listener and tnsnames files to standby db? What are the correct steps to do it? Any advice is greatly appreciated.

Thanks ackermsb for the reponse. I think I have confused of setting standby db and creating a HA. What I trying to achieve is creating a HA with vendor clusterware and oracle e.g. Sun Cluster HA for Oracle.
The steps involved in preparing the primary and standby oracle are:
Oracle application files – These files include Oracle binaries, configuration files, and parameter files. Need to installed separately in two servers locally.
The Database-related files – These files include the control file, redo logs, and data files are placed in a Cluster File System.
What I don't how to do it is, after installing the oracle binary in standby server, should I create the listener, tnsnames and pfile or copy them from the primary db?
Thanks in advance.

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 .........

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.

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.

Can anyone point direction to Upgrade Guides with Veritas Cluster solution?

Hello,
I would like to know if there's specific information about upgrading an R/3 system to ERP 6 which uses veritas cluster solution for high availability on Solaris 10
Are there any guides or considerations I should take into account before starting the upgrade process?
Thank you!

> 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.

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*

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

Good Day All, and thanks in advance…
During the installation of grid infrastructure(cluster) for Oracle 11.2 RAC One Node on AIX6.1 ( PROD) , ASM used. I am getting below errors when executing ./root.sh
Upon investigation ,I managed to get note: 1068212.1 from the support oracle site ( see below for details) . I might be hitting Unpublished bug 8670579. I also logged Severity 2 SR with Oracle support to get the bug/patch fix and no one has attended the call.
This might be configuration issue or otherwise , if you have experienced the same issue please assist ? ( if you need more logfiles please feel free to request)….
I ran the Cluster Verify Check – all passed.
Many Thanks

Hi,
We are also trying to install 11.2.0.2 Grid infrastructure for Oracle RAC One Node on AIX 6.1. We did a POC in our lab environment and after much struggle got that working. Now we are building 4 clusters in the production environment and the first cluster installation failed while running root.sh on node2. We already have a Sev1 ticket open with Oracle Support but have not heard anything.
Here is root.sh output from node2. The two node names are p01dou416 and p01dou417.
CRS-4402: The CSS daemon was started in exclusive mode but found an active CSS daemon on node p01dou416, number 1, and is terminating
An active cluster was found during exclusive startup, restarting to join the cluster

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.
Cheers,
Brian

Failover on zone cluster configured for apache on zfs filesystem takes 30 M

Hi all
I have configured zone cluster for apache service, i have used ZFS file-system as high available storage.
The failover takes around 30mts which is not acceptable. my configuration steps are outlined as below
1) configured a 2 node physical cluster.
2) configured a quorum server.
3) configured a zone cluster.
4) created a resource group in the zone cluster.
5) created a resource for logical hostname and added to the above resource group
6) created a resource for Highavailable storage ( ZFS here) and added to the above resource group
7) created a resource for apache and added to the above resource group
the failover is taking 30mts of time and shows "pending offline/online" most of the time
I reduced the number of retry's to 1 , but of no use
Any help will be appreciated
Thanks in advance
Sid

Sorry guys for the late reply,
I tried to switch the owners of RG to both the nodes simultaniously,which is taking reasonable time.But the failover for a dry run is taking 30mts
The same setup with SVM is working fine, but i want to have ZFS in my zone cluster
Thanks in advance
Sid
