Sun cluster and WS7
Where I can find documentation about ws7 and sun cluster?
Anyone has done this with version 7.?
sun cluster shipped with sun java enterprise system 5 does support web server 7. you can get JES5 bits from

and more information about JES from

my client is insisting on putting oracle RAC on top of sun cluster, the thing is i don't know what is the benifit of creating such an architecture, i tries to search on the internet but couldn't understand the benifits nor the advantage, Kindly if some one has implemented such an architecture to let us know the use and the benifits
Hi,
Here on my environment, there is SUNCluster only for single instances. The Clusterware Oracle is complete providing high availability and load balance for your database, you don't need sun cluster with this case, no advantages gained. The only thing controlled by SUNCluster on my RAC environment is QFS (Cluster file system from SUN).
If search on this forum, there are many discussion by this topic (suncluster X RAC) like this post Re: Sun Cluster.. Why?

Sun Cluster and EMC AX150 does not work
Hi All,
I tried to setup a Sun Cluster 3.2 (2x T2000) with an EMC AX 150 Storage. the device paths are highly instable and breaking down time and again. Tried to install Powerpath software of EMC but this time the did-devices are not recognized by Sun Cluster.
Any help will be appriciated.
P.S: does anybody know whether a MSA 1000 will work with Sun Cluster 3.2.
RegardsLooking at the EMC link on http://www.sun.com/software/cluster/osp/ it doesn't look like these storage systems have been tested by EMC and so may or may not work.
You could try using Sun's MPxIO rather than PowerPath. MPxIO is included in Solaris for free. Again, it may or may not work. You are unlikely to get support on either configuration until EMC has done the prerequisite engineering testing to resolve the sort of issues you are currently seeing.

Folks,
Did you come across any products, who SMFied their product and how it impacts their cluster installations ?. Please provide details if you have any
Thanks mUch
_DSince I am currently not aware of third party products shipping an SMF service for their application (which does not mean much, ie. they could well exist) I just make two generic statements:
1) If for that application a standard Sun Cluster agent exists, then the instructions for installing this data service would include to disable the SMF on the cluster nodes (like on pre Solaris 10 systems the legacy runlevel script would need to get deactivated).
2) If for that application no standard Sun Cluster agent exists, then one would have the ability to leverage the new proxy SMF resource types coming with Sun Cluster 3.2. They would use the SMF manifest to start and stop the application. Note that by using this resource type you would not have any application fault monitoring.
Details to 2) can be found at

Sun Cluster and DS6 within zones
It is possible to configure the sun cluster agent for cluster 3.1/ 3.2 in a DS6.0 zone?
It's supported?
thank you.Sun Cluster 3.1 u4 does support Zones for failover but as a blackbox ie failover of the complete zone.
I am not sure this will interact well with DS 6 Cluster Agent.
DS 6.0 has it's own Agent (SUNW.ds6ldap delivered in the SUNWldap-directory-ha package).
This package is available with JavaES 5 as part of the Cluster Agents bundle.
Now with regards to the documentation of the DS cluster agent and its use, unfortunately the only documentation is what I posted on my blog early March : <http://blogs.sun.com/Ludo/entry/directory_server_6_ha_with>

Hi all!
I'm about to set up an asymetric two-nodes cluster. Every node is powered with Smart-UPS. I want cluster to be shut down after some time of power-loss. How can I configure it? Should I use PowerChute plus additionally or Sun Cluster provides its own solution? And, if first, is there a solution for graceful shutting down a cluster using PowerChute plus? Where can I read about this task?Hi all!

Sun Cluster and Interconnect IP ranges
Can someone explain why Sun Cluster requires such large subnets for its interconnects ?
Yes, they use non-routable IPs but there are some cases where even these collide with corporate admin networks. I had one cluster I had to use that Microsoft automatic IP nework range to avoid IP conflict with corporate networks.You dont have to stick to default IP's or subnet . You can change to whatever IP's you need. Whatever subnet mask you need. Even change the private names.
You can do all this during install or even after install.

Is oracle 9.2.0.8 compatible with Sun Cluster 3.3 5/11 and 3.3 3/13?
Where can I check compatibility matrix?matthew_morris wrote:
This forum is about Oracle professional certifications (i.e. "Oracle Database 12c Administrator Certified Professional"), not about certifying product compatibility.
I concur with Matthew. The release notes for sun cluster and oracle for solaris might tell you. oracle 9.2.0.8 is out of support on solaris and I recall needing a number of patches to get it to a fit state ... and that is without considering sun cluster. Extended support for 9.2.0.8 ended about 4 years ago ... this is not a combination I would currently be touching with a bargepole! You are best to seek on MOS. -
IDS 5.0 and Sun-Cluster
I want to make IDS 5.0 highly available using SunCluster. I have few questions about it.
1. Can I install IDS on local disk and make it highly availbale. Sun-Cluster doc says it should be on shared disk.
2. I have an already installed IDS I want to make it highly available using Sun-Cluster, what steps I should follow to achive this.I suppose that the answer is that it is not a simple task and it depends on the kind of cluster you want to deploy.
I suggest that you carefully read the documentation of Sun Cluster and specifically the Directory Server specific parts.
The way to do it is different with Sun Cluster 2 and Sun Cluster 3.0....
Or you can request help from Sun Professional Services...

Sun Cluster 3.0 and VxVM 3.2 problems at boot
i 've a little problem with a two node cluster (2 x 480r + 2 x 3310 with a single raid ctl.)
Every 3310 has 3 (raid5) luns .
I've mirrored these 3 luns with VxVM, and i've mirror also the 2 internal (o.s.) disks.
One of the disk of the first 3310 is the quorum disk.
Every time i boot the nodes , i read an error at "block 0" of the quorum disk and then starts a fastidious synchronization of the mirrors. (sometimes also of the os mirror..)
Why does it happen?
Thanks.
Regards,
Mauro.We did another test today and again the resource group went into a STOP_FAILED state. On this occasion, the export for the corresponding ZFS pool timed-out. We were able to successfully bring the resource group online on the desired cluster node. Subsequent failovers worked fine. There's something strange happening when the zpool is being exported (eg error correction?). Once the zpool is exported, further imports of it seem to work fine.
When we first had the problem, we were able to manually export and import the zpools, though they did take quite some time to export/import.
"zpool list" shows we have a total of 7 zpools.
"zfs list" shows we have a total of 27 zfs file systems.
Is there any specific Sun or otherwise links to any problems with Sun Cluster and ZFS? -
Sun Cluster failed to switchover
Hi,
I have configured two node sun cluster and was working fine all these days.
Since yesterday, i am unable to failover the cluster to second node.
instead, resources are stopped and started again on the first node.
when i use the command "scswitch -z -g oracle_failover_rg -h MFIN-SOL02" in first node I am getting these messages on the console
Sep 28 17:53:16 MFIN-SOL01 ip: [ID 678092 kern.notice] TCP_IOC_ABORT_CONN: local = 010.010.007.120:0, remote = 000.000.000.00
0:0, start = -2, end = 6
Sep 28 17:53:16 MFIN-SOL01 ip: [ID 302654 kern.notice] TCP_IOC_ABORT_CONN: aborted 0 connection
Pl. suggest me to solve this problem.Those messages aren't important here. I think that might be related to the fault monitor being stopped.
As I said in the previous post, you need to diagnose this bit by bit. Try the procedure manually, i.e. stop Oracle on node 1, manually switch-over the disks and storage to node 2, mount the file system, bring up the logical address, start the database.
I expect there is something wrong with your configuration, e.g. incorrect listener configuration.
There is also a way of increasing the debug level for the Oracle agent. This is documented in the manuals IIRC.

RAW disks for Oracle 10R2 RAC NO SUN CLUSTER
Yes you read it correctly....no Sun cluster. Then why am I on the Forum right? Well we have one Sun Cluster and another that is RAC only for testing. Between Oracle and Sun, neither accept any fault for problems with their perfectly honed products. Currently, I have multipathed fiber hba's to a Storedge 3510, and I've tried to get Oracle to use a raw lun for the ocr and voting disks. It doesn't see the disk. I've made sure they are stamped for oracle:dba, and tried oracle:oinstall. When presenting /dev/rdsk/C7t<long number>d0s6 for the ocr, I get a "can not find disk path." Does Oracle raw mean SVM raw? Should I create metadisks?
"Between Oracle and Sun, neither accept any fault for problems with their perfectly honed products"...more specific:
Not that the word "fault" is characterization of any liability, but a technical characterization of acting like a responsible stakeholder when you sell your product to a corporation. I've been working on the same project for a year, as an engineer. Not withstanding a huge expanse of management issues over the project, when technical gray areas have been reached, whereas our team has tried to get information to solve the issue. The area has become a big bouncing hot potato. Specifically, when Oracle has a problem reading a storage device, according to Oracle, that is a Sun issue. According to Sun, they didn't certify the software on that piece of equipment, so go talk to Oracle. In the sun cluster arena, if starting the database creates a node eviction from the cluster, good luck getting any specific team to say, that's our problem. Sun will say that Oracle writes crappy cluster verify scripts, and Oracle will say that Sun has not properly certified the device for use with their product. Man, I've seen it. The first time I said O.K. how do we avoid this in the future, the second time I said how did I let this happen again, and after more issues, money spent, hours lost, and customers, pissed --do the math. I've even went as far as say, find me a plug and play production model for this specific environment, but good luck getting two companies to sign the specs for it...neither wants to stamp their name on the product due to the liability. Yes your right, I should beat the account team, but as an engineer, man that's not my area, and I have other problems that I was hired to deal with. I could go on. What really is a slap in face is no one wants to work on these projects, if given the choice with doing a Windows deployment, because they can pop out mind bending amounts of builds why we plop along figuring out why clusterware doesn't like slice 6 of a /device/scsi_vhci/ . Try finding good documentation on that. ~You can deploy faster, but you can't pay more! -
Hi Experts,
I am new to Sun Cluster and trying to build a Sun Cluster on Solaris 10 x86 boxes. Is there a document that will walk me through step by step on configuring the Sun Cluster.
Thanks in Advance.
Sunil.Sunil,
You can download the software and the documentation for free from the Sun web-site. Try reading the manuals. They are very detailed and contains many examples how to install the software.
Cheers

In the Installation of RAC the routine will ask me which Interface I will use for RAC Interconnect and I do not know if it does not matter which Interface I choose, because I nevertheless in any case I have an SPOF.
Can anybody help??
Thank you very muchSorry for the late reply, but the interface to pick is the clprivnet0. This load-balances over the available private interconnects under the covers and so does not represent a single point of failure.

Sun Cluster with Netapps - iSCSI quorum and network port
I am proposing Sun cluster with Netapps 3020C.
May I know
1) OS is Solaris 9. The SUN OSP says that we need to obtain an iSCSI license from Netapps. Is this the iSCSI initiator software for Solaris 9 to talk to the NAS quorum? Or do I need to purchased a 3rd party iSCSI initiator ?
2) We provide 2 network ports for the Netapps private NAS LAN. Is it a must to cater another dedicated network port for the iSCSI communication with the quorum?
3) If we need purchase a 3rd party iSCSI initiator, where can we get this? I have checked Qlogic and Cisco, they are both not suitable for my solution.
Appreciate your helpHi,
1) OS is Solaris 9. The SUN OSP says that we need to
obtain an iSCSI license from Netapps. Is this the
iSCSI initiator software for Solaris 9 to talk to the
NAS quorum? Or do I need to purchased a 3rd party
iSCSI initiator ?Have a look at http://docs.sun.com/app/docs/doc/817-7957/6mn8834r2?a=view
I read the "Requirements When Configuring NAS Devices as Quorum Devices"
section as this is the license for the iSCSI inititator software.
So you need to enable iSCSI on the netapps box and need to install a package from netapps (NTAPclnas) on the cluster nodes.
2) We provide 2 network ports for the Netapps
private NAS LAN. Is it a must to cater another
dedicated network port for the iSCSI communication
with the quorum?Have a look at http://docs.sun.com/app/docs/doc/819-0580/6n30eahcc?a=view#ch4_quorum-9
I don't read such a requirement there.
3) If we need purchase a 3rd party iSCSI initiator,
where can we get this? I have checked Qlogic and
Cisco, they are both not suitable for my solution.
Appreciate your helpI don't thibk you need such a 3rd party iSCSI initiator, unless this is stated in the above docs.
