Can I use Sun VTS to test on a Sun Cluster 3.1 node?

Hi,
I have seen some online documentation which suggests Sun VTS is not supported for use on a cluster node -
http://docs.sun.com/app/docs/doc/819-2993/intro-7?l=en&a=view&q=VTS
However there is not much detail here and I was wondering if anyone out there has used Sun VTS on a running cluster node before - or if there is an alternative we could use for SC3.1?
The node is an E2900, sol 10 with SC3.1...
would be interested in testing CPU and Memory only - no shared disks.
Thanks :)

My guess is that by running VTS, you could impose serious load on the system that will affect the node behavior, leading to e.g failover. Further, some tests with regard to storage might interfere in a problematic way.
Since VTS is a debugging tool, I would recommend to boot a suspect node outside the cluster in non-cluster mode. Then carefully only enable the CPU and memory tests. Don't do any storage tests.
Note that I did not do this myself - and as it is not supported, you do it at your own risk.

File System Sharing using Sun Cluster 3.1

Hi,
I need help on how to setup and configure the system to share a remote file system that is created on a SAN disk (SAN LUN ) between two Sun Solaris 10 servers.
The files in the remote system should be read/writabe from both the solaris servers concurrently.
As a security policy NFS mount is not allowed. Some one suggested it can be done by using Sun Cluster 3.1 agents on both servers. Any details on how I can do this using Sun Cluster 3.1 is really appreciated.
thanks
Suresh

You could do this by installing Sun Cluster on both systems and then creating a global file system on the shared LUN. However, if there was significant write activity on both nodes, then the performance will not necessarily what you need.
What is wrong with the security of NFS? If it is set up properly I don't think this should be a problem.
The other option would be to use shared QFS, but without Sun Cluster.

Can I install Sun Cluster on LDOM guest domain. Is Oracle RAC a supported c

Hello,
Can I install Sun Cluster on LDOM guest domains. Is Oracle RAC on LDOM guest domains of 2 physical servers a supported configuration from oracle?
Many thanks in advance
Ushas Symon

Hello,
The motive behind using LDOm Guest domains as RAC node is to have a better control of the resource allocation, since i will be having more than one guest domains which should perform different functions. The customer wants to have ORACLE RAC alone (without sun cluster).
I will have two T5120's and one 2540 shared storage.
My plan of configuration is to have
Control&IO Domain with 8VCPU, 6GB mem
one LDOM guest domain on each physical machine with 8 VCPU's, 8GB of memory, shared n/w and disks participating as RAC node's. (Don't know yet if i will use solaris cluster or not)
one guest domain on each physical machine with 12 VCPU's, 14GB of memory, shared n/w and disks participating as BEA weblogic cluster nodes (not on solaris cluster)
One guest domain on each physical machine with 4 VCPU's, 4GB of memory,shared n/w and disks participating as apache web cluster (on solaris cluster)
Now, My question is, is it a supported configuration to have guest domains as Oracle RAC participants for 11gR2 (either with or without solaris cluster).
If I need to configure RAC nodes on solaris cluster, is it possible to have two independent clusters on LDOM , one 2 node cluster for RAC and another 2 node cluster for apache web?
Kindly advise
Many thanks in advance

RAC: using Sun cluster or Oracle clusterware?

Going to build RAC on SUN machine (Solaris 10) and Sun SAN storage, couldn't decide how to build the foundation-----use Sun cluster 3.1 or Oracle clusterware?
Any idea? Thanks.

Starting with 10g Release 2, Oracle provides its own and indipendient cluster management, i.e., Clusterware which can be used as replacement for the OS specific cluster software.
You can still use the OS level cluster, in this case, Oracle Clusterware depends on OS cluster for the node information.
If you are on 10g, you can safely, go with Oracle Clusterware.

SUn Cluster with multiple nodes

Hi,
I am planning to setup Sun Cluster with 3+ nodes.
is it possible to configure sun cluster with just two network interfaces on each box. (One for Public access and second for cluster interconnection via dedicated switch)?
Thanks in advance for the help.

Yes, but only if the adapters support VLAN tagging.
That way you would be able to create two tagged VLANs on each adapter, one for public and one for private traffic. You'd also need a switch that supported VLAN tagging, but I think these are fairly common now.
If your NICs do not support tagging then you'd need to get another adapter to allow Sun Cluster to install.

Can I use OCI driver to test database connection in JDeveloper9.0.3

When using JDeveloper 3.2.3, I can use oci8 driver to test the databse connection.
Then I want oci8 driver work in JDeveloper9.0.2 or JDeveloper 9.0.3. However, it cannot work.
(Note: but thin driver works fine)
First, I read the help file and setup ORACLE_HOME environment variable and install
OCI client driver ocijdbc9.dll on my compuetr. Then some exception is happening when I test again.
So I want to know, does anyone succeed in testing the connection via oci driver
and how to fix this problem.
Thanks a lot.

Hi !
You MUST use jdbc library supplied with Oracle client ( so classes12.zip from $ORACLE_HOME/jdbc/lib ), not with JDeveloper - this one might be incopatible with oci native libraries.
I hope , this helps.

Can I use NI TestStand for testing ZigBee and Bluetooth transceivers and processors

Hi , I should create , maintain snd excute software test plans for testing low power wireless networks such as ZigBee, Bluetooth using Python scripts and QA Methodology .The test design includes testing
RF transceivers, RF transmitters, RF receivers, System-on-Chips, Front Ends, ZigBee Processors, Bluetooth LE Processors, and RFID reader
I am a LabVIEW Developer and familiar with testing RF Components using NI Hardware such as PXIe system but I am new to TestStand and Python. Can I use Teststand to develop and deploy the tests for this purpose and also LabVIEW instead of Python
If it is possible could you please let me know that are the advantage and disadvantage of using LabVIEW and NI Test Stand for these kind of test design and implementation.
I greatly appercaite your help and advice on this matter .Many thanks.

Hi en99,
I am unsure what you mean by usign LabVIEW instead of Python - what part of the system would LabVIEW replace? Usually if you were using Python in automated test, it would be to handle the test processing, which in this case is done by TestStand.
As for advantages of TestStand over LabVIEW, the main one which SunRS mentioned is that TestStand has a test management engine, which covers result logging and passing test parameters to the various test modules, which can be written in many languages. As I mentioned above, it is Python which is commonly used to write alternative test managament engines. It is possible to write one in LabVIEW, but for good results it must be carefully architected and is typically a very time-consuming task if you want to keep it modular and use it for other applications. TestStand also has a number of built in tools which help to monitor various aspects of the test sequences, as well as provide multithreading optimisations.
I hope this helps

Can I Use my eMac Hardware Test CD to test my G3 900mHz iBook?

Hi All!
Can I use my 1.25 mhz eMac's Hardware Test CD to test my G3 900mHz iBook? I'm getting different answers from people who haunt the forums on MacLife and MacNN and MacWorld, saying that it might or might not work or that the test programs aren't any different, and some say the Hardware test on TechTools covers all Macs so same's true of Apple test CDs. Since this is the Apple site I'm taking it to the horse's mouth here. What's the story?
Thanks!
Trudi

Rhonda,
To me, the way you rub shoulders with regular Apple users here is the way Apple people ought connect with their public. I'm not asking or expecting Apple PR/Tech/Admin to chat or even talk at all on these (their own...) forums, but it's dismaying to me that only one Apple guy/gal ever drops by on a blue moon to eavesdrop (much less comment) on any non-PR department filtered real-world qualms or feedback their own customers have. That you care enough for Apple's own customers manyfold over what Apple ought be doing CSR-wise sans pay makes me tip my hat to you and I hope some Mac magazine picks you up as a stringer consultant if not outright employee.

Can we monitor Sun Cluster events

Hi,
Whenever there are some events, issues in cluster, we see logs on the node consoles regarding the same. Is there any way to capture these
events through some other application? Better, is there any way by which we can send these events, in some standard format (protocol way) to some application that can send emails etc to administrators so that one need not keep eye continuously on the console for issus in cluster?

Well, I did not get a chance to experiment with CRNP, however, came up with a strategy that can be used.
First of all, we can do this with Solaris 9 and above as we do not have a resource type SUNW.Event available with Solaris 8. This resource type needs to be registered with only one resource group on the cluster, the resource group can be related to your data service.
So, one should first get the file SUNW.Event from the cluster source, copy it at /usr/cluster/lib/rgm/rtreg, also, copy corresponding RT_BASEDIR contents mentioned in this file at appropriate location. This directory contains start, stop, check and monitor scripts.
One can set the required properties SUNW.Event.
All this needs to be done on all the nodes.
The properties of this resource type cover the port and logical address (which is usually the cluster address) where the events would be sent. One can then write a client to listen to this port and process the events.
Hope this clarifies the point, please confirm if you see any issues with this.

Sun Cluster with three nodes

I need a manual or advices for introducing a third node in a RAC with Sun Cluster. I don't know if qourum votes readjust automatic or I have add new quorum votes manualy, if I have to add a thirn mediator in svm ... etc
A lot of thanks and sorry for my english

After you have added your nodes to the cluster you will need to expand the RGs node list to include the new nodes if you need the RG to run on them. This is not automatic. Something like:
# clrg set -n <nodelist> <rg_name>
Is what you need.
I'm not sure I understand what you said about the quorum count. Only nodes and quorum devices (QD) or quorum servers (QS) get a vote, cabinets do not. So each node gets a vote and a QD/QS gets a vote count equal to the number of nodes it connects to minus 1. Thus with a two node cluster, you have 3 votes with one QD. With a 4 node cluster with one fully connected QD/QS, you have 7 votes (after re-adding it).
Hope that helps,
Tim
P.S. <shameless plug> I can recommend a good book on the product: "Oracle Solaris Cluster Essentials" ;-)

Dependency between Sun Cluster 2.2 and Sun hardware ?

I am evaluating Sun Cluster 2.2 for the usage as clustering software within our project.
Can anybody say me, if there is a dependency between Sun Cluster 2.2 and Sun hardware ?
Can I use Sun Cluster 2.2 with other hardware platforms running Sun Solaris 7 and Veritas Volume Manager ?

I have had this discussion with fellow cluster admins, and we think a port of cluster 2.2 could be done to Intel running Solaris. And here is the BUT, BUT SUN does not support anything except a SPARC based cluster. So currently there is definately a depedancy bewteen the 2.2 software and the hardware.
Hope this helps

Can't use iPad for testing app

When I tried to run an app under development on my iPad 1, I get a message "a valid provisioning profile for this exectable was not found."
Under General > Profiles > the Develop App Games and Developer Provisioning are both green ticked as Verified.
So I can't use my iPad for testing the app, which was no problem when I was running OS Lion with XCode 4.2.
I'm now using Xcode 4.6 on Mountain Lion 10.8.2.
What could be the problem? Thank you.

Using Sun Traffic manager in SC

Dear Gurus
Is there any specfic requirement using Sun traffic Manager in Sun cluster
i am using Sun cluster 3.1 on Solaris 9
Regard

I'm not sure which meaning of 'specific' you're implying here. You could interpret the question as:
A. Do I have to run Sun traffic manager with Sun Cluster?
Answer: yes, if you have multiple paths to the same storage, otherwise it is superfluous.
B. Does Sun traffic manager depend on other s/w to run with Sun Cluster?
Answer: no, just Solaris and relevant patches.
C. Can I use something other that Sun traffic manager with Sun Cluster?
Answer: yes, with EMC you can use PowerPath and with HDS you can use HDLM (?), but you can't use VxDMP.
Hope that helps,
Tim
