Cross-WAN Cluster Configuration in JMQ

Hi MQ experts,
Here I have some questions regarding the JMQ cluster configuration
with regard to the cross WAN support. Let say there are two JMQ
brokers located in two different geo locations (e.g. one in NY and the
other in SF) configured to participating in the same JMQ cluster, and
several JMQ clients are configured to talk to their local JMQ broker in
either site.
Given the above configuration, here are my questions:
* Does this configuration work from the functionality point of view?
* What is the protocol/mechanism used for the inter-broker communication?
* Does this configuration (cross WAN) work from the performance's point of view? If so, is there s is any specific configuration that needs to be done (for instance, we heard if HTTP is being used for the data synchronization between these two brokers across the WAN then it's possible, etc.)?
* For the clients on each site, if the home broker fails, then does the failover mechanism work well in this cross-WAN configuration?
* If this is indeed a supported configuration, is there any other documentation/performance benchmark reporting from which we can get more information?
Thanks in advance for any information that you can share with us.
-Alan

hi alan,
1) yes it will work functionally
2) dont know exactly but i think there are several
3) what will you use about openmq? what are the charackteristics for your usage? queues/topics temp queues .... lots of things to ask.
4) it will work
5) i think it is not supported since WAN capabilities are just in development and are planned for the next releases.

Live migration to HA failed leaving VHD on local storage and VM in cluster = Unsupported Cluster Configuration

Hi all
Fun one here, I've been moving non-HA VMs to a HA and everything has been working perfectly until now. All this is being performed on Hyper-V 2012R2, Windows Server 2012R2 and VMM 2012R2.
For some reason on the VMs failed the migration with an error 10608 "Cannot create or update a highly available virtual machine because Virtual Machine Manager could not locate or access Drive:\Folder" The odd thing is the drive\folder is
a local storage one and I selected a CSV in the migration wizard.
The net result is that the VM is half configured into the cluster but the VHD is still on local storage. Hence the "unsupported cluster configuration" error.
The question is how do I roll back? I either need to get the VM out of the cluster and back into a non-HA state or move the VHD onto the CSV. Not sure if the latter is really a option.
I've foolishly clicked "Ignore" on the repair so now I can't use the "undo" option (brain fade moment on my part).
Any help gratefully received as I'm a bit stuck with this.
Thanks
Rob

Hi Simar
Thanks for the advice, I've now got the VM back in a stable state and running HA.
Just to finish off the thread for future I did the following
- Shutdown the VM
- Remove the VM from the Failover Cluster Manager (as you say this did leave the VM configuration intact)
- I was unable to import the VM as per your instructions so I copied the VHD to another folder on the local storage and took a note of the VM configuration.
- Deleted the VM from VMM so this removed all the configuration details/old VHD.
- Built a new VM using the details I saved from the point above
- Copied the VHD into the new VMs folder and attached it to the VM.
- Started it up and reconfigured networking
- Use VMM to make the VM HA.
I believe I have found the reason for the initial error, it appears there was a empty folder in the Snapshot folder, probably from an old Checkpoint that hadn't cleaned up properly when it was deleted.
The system is up and running now so thanks again for the advice.
Rob

Hyper-V Failover Cluster Configuration Confirmation

Dear All,
I have created a Hyper-V Failover Cluster and I want you to confirm if the configuration I have done is okay and I have not missed
out anything that is mandatory for a Hyper-V Failover Cluster to work. My configuration is below:
1. Presented Disks to servers, formatted and taken offline
2. Installed necessary features, such as failover clustering
3. Configured NIC Teaming
4. Created cluster, not adding storage at the time of creation
- Added disks to the cluster
- Added disks as CSV
- Renamed disks to represent respective CSV volumes
- Assigning each node a CSV volume
- Configured quorum automatically which configured the disk witness
- There were two networks so renamed them to Management and Cluster Communication
- Exposed Management Network to Cluster and Clients
- Exposed Cluster Communication Network to Cluster only
5. Installed Hyper-V
- Changed Virtual Disks, Configuration and Snapshots Location
- Assigned one CSV volume to each node
- Configured External switch with allow management option checked
1. For minimum configuration, is this enough?
2. If I create a virtual machine and make it highly available from hyper-v console, would it be highly available and would live
migrate, etc.?
3. Are there any configuration changes required?
4. Please, suggest how it can be made better?
Thanks in advan

Hi ,
Please refer to following steps to build a hyper-v failover cluster :
Step 1: Connect both physical computers to the networks and storage
Step 2: Install Hyper-V and Failover Clustering on both physical computers
Step 3: Create a virtual switch
Step 4: Validate the cluster configuration
Step 5: Create the cluster
Step 6: Add a disk as CSV to store virtual machine data
Step 7: Create a highly available virtual machine
Step 8: Install the guest operating system on the virtual machine
Step 9: Test a planned failover
Step 10: Test an unplanned failover
Step 11: Modify the settings of a virtual machine
Step 12: Remove a virtual machine from a cluster
For details please refer to following link:

Hello Krishna,
Any luck fixing this issue? I am experiencing the same issue. Please advise, thank you.

Unsupported Cluster configuration.

Hi
Im getting below error on refershing the host cluster I get below error . I have 2 hosts in the cluster and VMs report unsupported cluster configuration. SCVMM 2012 SP1 dont seem to see the Logical Switches . Although Upon restarting WMI Services on the
host seem to fix the issue but after couple of weeks time I get the same error again. Upon doing some research I suspect when NIC Team moves the VNICs around and SCVMM agent doesnt get the latest information and therefore shows this error .
Solutions I have applied so for and get no joy are below
1. No snapshots are saved
2. No ISO files are mounted
3. VSS service set to manual
4. Host switches have same name
5. all VHD files are stored on CSV Volumes.
6. Set one NIC in team as standby because MAC Address of the host management network is same as physical address as I have inherited the settings while creating logical networks.
Can Anyone please help

Hi Ed -
thanks for response
Although the other thread is referring to same error . I have already read that thread before starting a new one. This has been a known issue from 2008 R2 era . I have updated my SCVMM 2012 SP1 to rollup 7 but still seem to be an issue somewhere . I
can confirm that DNS server are same on both the hosts .
Does anyone think of anything else . Im happy to post the logs if anyone knows .
Thanks

O2cb_ctl : unable to load cluster configuration file while RAC setup.

OCFS2: unable to load cluster configuration file
Hi,
I installed OCFS2 successfully.
I successfully install 3 RPMs.
I am getting error while running ocfs2console to do cluster configuration.
I tried to run this manully using "o2cb_ctl -C -n NODENAME -t node -a number=NODENUM -a ip_address=IPADDR -a ip_port=IPPORT -a cluster=CLUSTERNAME "
this commnd. but getting error as
"o2cb_ctl: Unable to access cluster service while creating node Could not add node "
Then I edited this file manually and copied to another nodes using SCP. Then tried to use o2cg_ctl utility as
# /etc/init.d/o2cb offline ocfs2
# /etc/init.d/o2cb unload
# /etc/init.d/o2cb configure
Configuring the O2CB driver.
Next, I configure /etc/ocfs2/cluster.conf:
cluster:
node_count = 2
name = oracle
node:
ip_port = 7777
ip_address = 140.187.222.222
number = 1
name = ocvmrh2053
cluster = oracle
node:
ip_port = 7777
ip_address = 140.187.222.222
number = 2
name = ocvmrh2051
cluster = oracle
Next, I try to load ocfs2 modules by command: o2cb load - everything messages is OK
And I try switch ocfs2 cluster to online (by o2cb online oracle), write this error message:
Starting cluster oracle: Failed
o2cb_ctl: Unable to load cluster configuration file "/etc/ocfs2/cluster.conf"
Stopping cluster oracle: Failed
o2cb_ctl: Unable to load cluster configuration file "/etc/ocfs2/cluster.conf"
I think both errors i get are due to same issue. Please kindly reply if anyone having idea.
Thanks.
Please anyone can help me to resolve this.

Windows 2003 Standard Edition (Cluster Configuration Storage page)

I am trying to install RAC R2 on windows Server 2003 (Standard Edition). I am using FireWire 800 SIIG to connect to Maxtor OneTouch III External HDD.
When installing cluster Services, i do not see the Cluster Storage Devices. When i go to Computer Management, i see all the partitions of the raw device.
One "Cluster Configuration Storage" page, the Available Disks show no partitions.
Oracle installtion documentation says "On the Cluster Configuration Storage page, identify the disks that you want to use for the Oracle Clusterware files and, optionally, Oracle Cluster File System (OCFS) storage. Highlight each of these disks one at a time and click Edit to open the Specify Disk Configuration page where you define the details for the selected disk"
In my case, i do not see any disks. What am i missing?
Any Thoughts. Please advise
Thanks

You have a more fundamental problem, Firewire disks will not work for RAC on Windows. The storage needs to be shared, Firewire disks can't be shared on Windows. On Linux, Oracle took the open source firewire driver and modified it to allow more than one host to connect. On Windows the driver is closed source so they can't do that.
I presume you are wanting to try-out RAC on Windows, If so another solution may be to download one of the many iSCSI Servers that are available. Microsoft ship an iSCSI Initiator for Windows, this allows you to share a 'block device' which is what RAC needs - then you can choose your RAC Database storage method of choice, ASM, OCFS, RAW. I prefer ASM

How to install webcenter sites 11.1.1.6 or 11.1.1.8 in cluster configuration and delivery mode?

I am trying to install webcenter sites 11.1.1.6 using cluster configuration and in delivery mode but its not getting installed properly.
Can anyone please share on the steps to follow while installing webcenter sites in delivery environment?

The recommendation from the Oracle WebCenter & ADF Architecture Team is to keep the parts decoupled, installing WebCenter Sites on a separate machine. Otherwise it would be leading towards a 'Type 3' integration. Specifically looking at the proof-of-concept application 'Spark', which requires WebCenter Sites and WebCenter Portal installed on the same machine:
+"Due to this co-deployment requirement, most clients have avoided installing or using Spark. And not without reason: installing two big, complex applications on the same environment is problematic with regards to scalability and tuning."+

License Cisco ESA in Cluster Configuration

Guys,
Do you have any idea about license Cisco ESA in Cluster Configuration
> If i have two appliance in cluster configuration and i have 1000 user, which option for license i must buy ?
1. Just one license for two appliance (which in cluster configuration) with 1000 user capacity
2. Two license with 500 user capacity for each appliance, appliance 1 with 500 user capacity license appliance 2 500 user capacity license
3. Other license.
BR

You only need to buy 1000 user licenses for which ever options or packages you buy. The only option that is not based on the number of users is if you want a Cisco Content Security Management Appliance or SMA for centralized reporting and quarantine.
Another good thing to note, is that if you have a virtual environment the hardware appliances are no longer required, and are not nearly as expensive as they were in the past. So depending on your requirements you may be off the ground pretty quick.
Also make sure to get all your features bundled. I would at least get AMP, Sophos A/V, DLP, and Encryption. This also means you can transfer and copy your license to as many appliances (Physical or Virtual) you need to support your environment.

No shared disks visible in the Cluster Configuration Storage dialog

When installing the Oracle 10g clusterware the "Cluster Configuration Storage" dialog shows no shared disks.
We are using:
Windows 2003 Server
HP Eva 4400

Hello,
all disks in cluster are visible from all nodes (2 of them).
We tested it with unpartioned and partioned disks (primary and extended). No way to make them visible for the OUI.
Automount is enabled in Windows like required from Oracle.
Besides, we are using Standard Edition. Therefore we have to work with ASM.
Any more information needed.
Thanx in advance.

No partitions avalilable on Page Cluster configuration storage

hello all,
I am trying to install RAC R2 on windows Server 2003 (Standard Edition) with 2 nodes.
When installing Clusterware. I can't see all the partitions of the raw device but When i go to Computer Management, i see all of them.
One "Cluster Configuration Storage" page, the Available Disks show no partitions.
I have check the next document:
http://download.oracle.com/docs/cd/B19306_01/install.102/b14207/storage.htm#sthref244 But Unfortunately I can´t solve the problem
Please Advice, Thanks in advance.

I presume you have tried and failed to install a few times and each time the list of partitions available has decreased.
if you have access to metalink you should see note :341214.1 on how to correctly clean up a failed install.

The local node entry in Cluster Configuration information does not match wi

In installing 10.1.0.3 CRS on Solaris 8 x86, I keep getting the error, "The local node entry in Cluster Configuration information does not match with the entry in /etc file." Both addresses are defined in the /etc/inet/hosts and are pingable. There seems to be no way to get past this issue. Earlier I installed 10.2.0.1 CRS on SLES9 SP2 on a system with the same network settings and had no problem. Is there some way to force the installer to accept the addresses given and proceed past this step?

All,
I think there can be two problems
1.
if your host file looks as follows
# Public
192.168.2.x rac1.localdomain rac1
192.168.2.x rac2.localdomain rac2
#Private
192.168.0.x rac1-priv.localdomain rac1-priv
192.168.0.x rac2-priv.localdomain rac2-priv
#Virtual
192.168.2.x rac1-vip.localdomain rac1-vip
192.168.2.x rac2-vip.localdomain rac2-vip
then you should be able to do rsh or ssh sucessfully for each aliases at least one from each nodes
(ex)
on node rac1
ssh rac1 date
ssh rac1.localdomain date
ssh rac2 date
ssh rac2.localdomain date
2. you should create user equivalance on all the nodes as follows
Edit the /etc/hosts.equiv file to include all the RAC nodes:
+rac1 oracle
+rac2 oracle
+rac1-priv oracle
+rac2-priv oracle

Does SOA 10.1.3.1 suite support Cluster configuration

Hi,
Does SOA 10.1.3.1 suite support Cluster configuration, if so, how can it be clustered? Is there any document available?
Thanks in advance!

Yes. SOA 10.1.3 is certified to use Oracle Database 11g Release 2 (11.2) with some guidelines, known issues, and exceptions. You may refer Metalink Note ID 887365.1

Cluster Configuration in WebLogic 10.3.5

I have some doubts about clustering in WebLogic.
1) I have created two MS(Managed Servers) in one machine: MS1(port 7003),MS2(port 7013). The MS2 should be the backup for MS1 when something wrong happens. So MS1 and MS2 have to be agreggated to my cluster configuration or just MS2?
2) I have created the cluster ,with the Admin Console, assuming I have to agregate just MS2. ¿Do I need to do another configuration? I don't know exactly what are the steps to complete the cluster.

Hi,
You are going in the right track.
First make sure that you have a standalone server,in your case (AdminServer) to distribute the requests to the other Managed servers.
1)Create the two managed servers.
2)Add all the servers in the cluster
3)create a machine and add MS1 and MS2.
4)Run the node manager from the directory <oracle_home>/wlserver10.3/server/bin/nodemanager.cmd
5)Now try to start the managed servers.
optionally...add the below argument in the managed servers... Home >Summary of Servers >Summary of Clusters >Cluster_1 >ms1
-Xms512m -Xmx512m -XX:MaxPermSize=512m
Clustering achieved-
But wait, now this is not the end of things... :)
Now you need to achieve Load balancing, to actually see how the clustering behaves.
cheers,
