Sun Cluster 3.2, Zones, HA-Oracle, & FSS

I have a customer who wants to deploy a cluster utilizing Solaris 10 Zones. With creating the resource groups with the following: nodeA:zoneA, nodeB:zoneA, the Oracle resource group will be contained in the respective zone.
First create the Zone after the Sun Cluster software has been installed?
When installing Oracle, the binaries and such should reside in the Zone or in the global zone?
When configuring FSS, should this be done after the resources have been configured?
Thanks in advance,
Ryan

The Oracle biaries are not big at all, ther is not much IO happening at this fs, you can easily create a ufs file system for each zone, mount that via lofs mounts into the zone. Or you can create a zpool for the binaries. My personal take would be to include them in the root path of the zones an you are set.
You must install the binaries in all zones where your Oracle database can fail over to. To reduce the maintenance work in the case of upgrades I would limit the binary installation to the zones in the nodelist of your oracle resource group. If you install the binaries on all nodes/zones of the cluster you have more work when it comes to an upgrade.

Sun Cluster 3.2 running 2 oracle instance

I have the following situation:
Server A: contain DB_A, SID: oraclea, same oracle home path but different alert file
Server B: contain DB_B, SID: oracleb, same oracle home path but different alert file
Server C: standby, same oracle home path and Server A & B alert files.
I success register Oracle server resource and listener resource.
Failover DB_A to Server C, it's success.
After this failover DB_B to Server C. Cluster log shown fail and DB_B failback to Server B.
However, if Server C haven't own DB_A resource group. Failover DB_B to Server C success.
It seems cannot own 2 oracle server in the same time.
May I know what happen and what setting I am missing?
Another question is I create one resource group contain 2 oracle server services. Create 1st one is success and failover also success but creating the 2nd instance, whole resource group will go offline.
May I know what happen and what setting I am missing?
Hedgehog

Case fixed by enter kernel parameter for oracle in /etc/system; wonderful thing is /etc/system without kernel parameter also can startup another DB but failover.
Summary:
1. DB_A failover to Node C success
2. DB_B failover to Node C success (with kernel parameter)
else
1. DB_A failover to Node C success
2. DB_B failover to Node C fail (without kernel parameter, even increase system swap)
-> DB_B can startup manually (not control by cluster, without kernel parameter)

Deploy HA Zones with Sun Cluster

Hi
I have 2 physical Sol 10 Servers with a storedge array for the shared storage.
I have installed Sun Cluster 3.3 on both nodes and sorted the quorum and shared drive using a zfs file system for a mount point
Next i have installed a non global zone on 1 node using the zone path on the shared filesystem
When i switch the shared file system the zone is not instaalled on the 2nd node.
So when i try to install the zone on the 2nd node
i get a Rootpath is already mounted on this filesystem
Does anyone know how to setup a Sun Cluster with HA Zones please.

The option to forcibly attach a zone got added to zoneadm with a Solarus 10 Update release. With that option the procedure to configure and install a zone for HA Container use can be:
The assumption is there is already a RG configured with a HASP resource managing the zpool for the zone rootpath:
a) Swithch the RG online on node A
b) Configure (zonecfg) and install (zoneadm) the zone on node A on shared storage
c) boot the zone and go through interactive sysidcfg within "zlogic -C zonename"
d) Switch the RG hosting the HASP resource for the pool to node B
e) Configure (zonecfg) the zone on node B.
f) "Install" the zone by forcibly attaching it: zoneadm -z <zonename> attach -F
The user can then test if the zone boots on node B, halt it and proceed with the sczbt resource registration as described within http://download.oracle.com/docs/cd/E18728_01/html/821-2677/index.html.

Heading 1: Sun Cluster with Zones using IP type=exclusive

Dear Forums Members,
I am trying to install a Sun Cluster with Clustered Zones that the IP type=exclusive.
This does not seem possible as the IPMP does not work.
Any ideas?
Thanks
Wayne

Hi,
The network interface should NOT be a legacy one.
To Check run the following
dladm show-link the interface should not be legacy type
Also when zonecfg add net just set the physical attribute, set the address inside the zone when it is up.

Without speculating on the release date of Sun Cluster 3.x or even its feature list, I would like to understand what risk Sun would take when Sun Cluster would support ZFS as a failover filesystem? Once ZFS is part of Solaris 10, I am sure customers will want to use it in clustered environments.
BTW: this means that even Veritas will have to do something about ZFS!!!
If VCS is a much better option, it would be interesting to understand what features are missing from Sun Cluster to make it really competitive.
Thanks
Hartmut

Availability of Sun Cluster 3.2

Has anyone some news about the release date and the new features of Sun Cluster 3.2. It was once announced by end of 2006.
Fritz

Hi Tim
I more or less expected this answer from you ;-)
We are planing to use the Sun Cluster to switch Zones / Containers as GDS between nodes. We have currently some installations with Sun Cluster 3.1, but we are now in the process of evaluating a framework to deploy Solaris Zones in a large scale. This would also include containers in a clustered environment. There Sun Cluster 3.2 seems to have some interesting new features.
Unfortunately I had not the resources to paritipizate in the beta program.

Failover Zones / Containers with Sun Cluster Geographic Edition and AVS

Hi everyone,
Is the following solution supported/certified by Oracle/Sun? I did find some docs saying it is but cannot find concrete technical information yet...
* Two sites with a 2-node cluster in each site
* 2x Failover containers/zones that are part of the two protection groups (1x group for SAP, other group for 3rd party application)
* Sun Cluster 3.2 and Geographic Edition 3.2 with Availability Suite for SYNC/ASYNC replication over TCP/IP between the two sites
The Zones and their application need to be able to failover between the two sites.
Thanks!
Wim Olivier

Fritz,
Obviously, my colleagues and I, in the Geo Cluster group build and test Geo clusters all the time :-)
We have certainly built and tested Oracle (non-RAC) configurations on AVS. One issue you do have, unfortunately, is that of zones plus AVS (see my Blueprint for more details http://wikis.sun.com/display/BluePrints/Using+Solaris+Cluster+and+Sun+Cluster+Geographic+Edition). Consequently, you can't built the configuration you described. The alternative is to sacrifice zones for now and wait for the fixes to RG affinities (no idea on the schedule for this feature) or find another way to do this - probably hand crafted.
If you follow the OHAC pages (http://www.opensolaris.org/os/community/ha-clusters/) and look at the endorsed projects you'll see that there is a Script Based Plug-in on the way (for OHACGE) that I'm writing. So, if you are interested in playing with OHACGE source or the SCXGE binaries, you might see that appear at some point. Of course, these aren't supported solutions though.
Regards,
Tim

Does sun Cluster 3.0/3.1 HA Oracle agent support to use Oracle spfile?

When defining the resource, the 'parameter_file' properties is usually sets to the Oracle pfile. Is it possible to use Oracle spfile?
It is said if leaving 'parameter_file' NULL, it will be default to Oracle default. Suppose leaving it NULL and with Oracle spfile created in default location, will it use the spfile?

You did not specify which Sun Cluster version and Oracle version you are running.
Within SC 3.1 my understanding is that beginning with Oracle 9i it is possible to use the spfile.
If you leave the "parameter_file" property empty (NULL) then the default behaviour for 9i should work:
search under $ORACLE_HOME/dbs in the order:
1. spfile$(ORACLE_SID}.ora
2. spfile.ora
3. init${ORACLE_SID}.ora

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:,

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

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.

DS6 in a zone on a Sun Cluster

I have a sun cluster that I am trying to configure and I don't know if I am trying to do something wrong, so I thought I would ask.
I am using Sun Cluster 3.2 on a pair of Sun T2000s with a Fiber Channel disk array attached to both nodes. I have configured the disk array to have two file systems. One for each server. I have configured two resource groups in the global zone and setup a HAStoragePlus resource for each file system. I am successfully able to fail the file systems between the two nodes. On each of the file systems I have installed a zone. The zone is managed with the resource type provided by the SUNWsczone package to start and stop the zone. The resource is in the same resource group has the HAStoragePlus resource.
At this point I have created resource group for the zone to manage the directory server. After creating the resource group I am trying to create a resource for the directory service HA service. When I use the clresource command it complains that the resource group does not contain a logical hostname. When using the services provided by the SUNWsczone package I created a logical hostname that is being assigned to the zone in question. Is there a way to install the Directory Server HA resource into the resource group for the zone?

Philippe,
DS 6 Sun Cluster Agent was not tested with SC 3.2 in Zones.
Zone support came with SC 3.2, and DS 6 Cluster Agent was built with SC 3.1, tested with SC 3.1 and 3.2 in the Global zone.

SUN CLUSTER RESOURCE FOR LEGATO CLIENT (LGTO.CLNT) in Oracle database

hi everyone
I am tryinig to create a LGTO.clnt resource in oracle-rg resource group in SUN CLUSTER 3.2 with the following commands
clresource create -g resource_group_name -t LGTO.clnt \
-x clientname=virtual_hostname -x owned_paths=pathname_1,
pathname_2[,...] resource_name
I just need to know what is value of Owned_Paths variable in the above commnad?
or what PATH it is reffering to ( $ORACLE_HOME or Global devices path ...etc) ?

Hello,
The Owned_Paths parameter are the paths (or mountpoints) the legato client will be able to backup from.
To configure a legato client in the Networker console (and to be managed as a cluster client) you need to declare the in the Owned_Paths the paths you want to save.
The savesets paths can be a directory under the Owned_Paths.

Pablo Villanueva.

Multiple Oracle databases in Sun cluster 3.2 (without RAC setup)

There are 2 Sun SPARC (Sun Fire T2000) servers with Solaris 10 (05/09) OS and Sun Cluster 3.2 software. We need two different Oracle databases & instances (Oracle 10g R2 without RAC) for an application. The first database is for Production and need to be configured in the first node & Shared storage disk and need high availability. This database should run from the second node if the first node fails. The second database is for Quality/Test and it is prefered to be running in the Second node for better load distribution. This DB doesnt require any failover.
The shared storage is Sun SE 3510 FC and multiple LUNs can be created for different databases..
Is it possible to configure two different resource groups (one for Quality and other for Production) and make the first node primary for Production RG, and the second node primary for Quality RG and thus distributing the load on 2 servers ? If possible, what special configuration required in Sun OS and Cluster side ?
Appreciate if you can give some configuration procedures/documents for this multi-master cluster setup..

You can configure two resource groups, such as:
# clrg create -n node-a,node-b prod-rg
# clrg create -n node-b qa-rgand you configure the required resources (disk groups / file systems, logical host, oracle listener, oracle server) as described within
[http://docs.sun.com/app/docs/doc/819-2980?l=en&a=expand|http://docs.sun.com/app/docs/doc/819-2980?l=en&a=expand]
Note that this is not really called a "multi-master" configuration - that has a specific meaning for a resource group (see [http://docs.sun.com/app/docs/doc/820-4682/babefcja?l=en&a=view|http://docs.sun.com/app/docs/doc/820-4682/babefcja?l=en&a=view] ) for details.
With Solaris Cluster all nodes part of a cluster are considered active and can host resource groups. You can have any number of resource groups running, where a subset runs one one node, another subset on other nodes. The nodelist property of the resource group defines where it can run, the first node in the list is the preferred primary.
You can even define resource group dependencies or affinities between the resource groups. Like you could define a negative affinity between qa-rg and prod-rg, such as if prod-rg needs to failover to node-b (since e.g. node-a died), it would offline qa-rg. Details for that kind of possibilities are described at [http://docs.sun.com/app/docs/doc/820-4682/ch14_resources_admin-35?l=en&a=view|http://docs.sun.com/app/docs/doc/820-4682/ch14_resources_admin-35?l=en&a=view].

How to install a SUN cluster in a non-global zone?

How do I install a SUN cluster in a non-global zone? If it is the same as installing SUN Cluster in the global zone, then how do I access the cdrom from a non-global zone to the global zone?
Please point me to some docs or urls if there are any. Thanks in advance!

You don't really install the cluster software on zones. You have to set up a zone cluster once you have configured the Global Zone cluster (or in other words, clustered the physical systems + OS).

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
