Cluster Virtual IP addresses - cluvfy utility error

Hi,
I've just about to install Oracle 10.2.01 Clusterware on a 2 node RAC running RHEL4 AS. I'm basically following Jeffery Hunters Guide - http://www.oracle.com/technology/pub/articles/hunter_rac10gr2.html
Each node has 2 ethernet cards - eth0 as public and eth1 as private. The hosts files contain entries for these, and a 2nd set of public IPs for use as VIPs
I've run the cluvfy utility for pre cluster installation checks and I'm getting a VIP error. The utility finds suitable interfaces for interconnects, but fails to find suitable interfaces for VIPs.
Has anyone any ideas what checks cluvfy is running and what might make them fail?
Thanks,
Thom

Changing Hyper-V host and cluster virtual IP addresses to new subnet/VLAN

I have a 2 node Hyper-V 2012 R2 failover cluster, managed by System Center Virtual Machine Manager 2012 R2, and I would like to change the IP addresses of the hosts and the cluster, in order to move them to a new subnet and VLAN. The existing and new subnets
are able to route to each other so all hosts will still be able to communicate throughout the parts of the process where they may be on separate subnets. There is also a dedicated cluster heartbeat network on its own subnet and VLAN that I am not altering
in any way.
The 2 hosts are configured with 4 nics in a team, with dedicated virtual interfaces for each of the following:
-Live Migration
-Cluster Heartbeating
-Host management/general traffic (the cluster virtual IP address is also on the same subnet as these interfaces).
It is the host management/general traffic addresses that I want to change. The interfaces were created and configured with the Add-VMNetworkAdapter, New-NetIPAddres and Set-VMNetworkAdapterVlan commands.
Please advise if the following process is correct:
1) Evacuate all the VMs from the first host to be changed and put it in maintenance mode.
2) Use Set-VMNetworkAdapter to change the name of the interface (the current name refers to the VLAN it's on)
3) Use Set-NetIPAddress to change the IP address and gateway of the interface as appropriate
4) Use Set-VMNetworkAdapterVlan to set the VLAN ID
5) Take the host out of maintenance mode and move all VMs off the other host
6) Repeat above steps on the other host
I know that I will then need to change the cluster virtual IP address, but I have no idea how to do this or where to look for that setting. Please advise!
Cheers.

Sun cluster: virtual IP address

Hi,
What is the virtual IP address and how to configure it?
For example, should it be defined in /etc/hosts? dns?
Thank you,

[[[s this correct to have apache HA?]]]
Apache can be set up as a failover resource (so it is active only on one node at a time) or a scalable resource (where it would be active on multiple nodes at the same time).
[[[Just an aside question: HAStoragePlus is NFS sharing? What is difference between NFS resource and mount resource (I saw Veritas differentiate between them)? In case I set up a shared disk, is it NFS or mount resource?]]]
HAStoragePlus is not NFS sharing. HAStoragePlus let's you create HA storage (it's called HAStoragePlus because there was an earlier generation data service (aka Clustering Agent a-la VCS) called HAStorage). This will let you wrap a shared storage device and fail it back and forth between multiple nodes of the cluster.
NFS sharing has to be handled using the SUNW.nfs Data service (or in other words, the NFS clustering agent) (ie only if you want to set up NFS as a HA service). Otherwise, you can use standard NFS.
Mount resource is (i'm guessing here) any resource that can be mounted. In other words, a Filesystem.
NFS resource is a resource that is shared out via NFS.
[[[Also, a basic question: The shared disk should not be mounted in /etc/vfstab. Correct? It should be only present when doing format on each node. Right? It is SCS that manages the mounting of the file system? This should be up before testing apache HAno?]]]
That is correct. Sun Cluster will handle mounting/unmounting the filesystem and importing/deporting the disk set (in Veritas world it is called a Disk group).
When you build your cluster resource group (aka VCS Service group), you will have to build the dependency tree (just how you would in VCS).
1) Create empty RG
2) Create HAStoragePlus Resource
3) Create Logical Hostname resource
4) Create Apache resource
5) define dependency of Logical hostname (Virtual IP) and HAStoragePlus (filesystem) so that apache can start.
At each stage, you can test whether the RG is working as it should before proceeding to the next level.

Virtual IP address in Failover Cluster Manager

Dear All,
I want assign virtual IP address to cluster server windows 2012 but this Ip address is not given to physically.
i am creating host entry with ip address and hostname but i am not able to ping.
is there any way to ping this ipaddress?
i am only creating entry in host file.

Information on the Virtual IP Address of cluster resource group

Hi,
I would like to know how we can find a Virtual IP address of resource group. i.e. The IP address associated to the SUNW.LogicalHostname resource of the resource group.
Is it always present in the output of the command 'ifconfig -a'?
What is difference between IPMP and the Virtual IP Address of the resource groups? Can these IP Addresses be common / same?
Thanks,
Chaitanya

Chaitanya,
There seems to be a little confusion in your question so let me try and explain.
Resource groups do not necessarily have to have a logical (virtual) IP address. They will only have a logical IP address if you configure on by adding a SUNW.LogicalHostname resource to the resource group. When you create that resource, you give it the hostname of the IP address you want it to control. This host name should be in the name service, i.e. /etc/hosts, NIS, DNS, LDAP.
When you have added such a resource to a resource group (RG), bringing the RG online will result in the logical IP address being plumbed up on one of the NICs that form the IPMP group that host the relevant subnet. So, if you have two NICs (ce0, ce1) in an IPMP group that support the 129.156.10.x/24 subnet and you added a logical IP address 129.156.10.42 to RG foo-rg, then bringing foo-rg online will result in 129.156.10.42 being plumbed in on either ce0 or ce1. ifconfig -a will then show this in the output, usually as ce0:1 or ce0:2 or ce1:3, etc.
An IPMP group is a Solaris feature that supports IP multi-pathing. It uses either ICMP probes or link detection to determine the health of a network interface. In the event that a NIC fails, the IP addresses that are hosted on that NIC are transferred to the remaining NIC. So, if your host has an IP of 129.156.10.41 plumbed on ce0 and it fails, it will be migrated to ce1.
That's a very short description of a much more detailed topic. Please have a look at the relevant sections in the Solaris and Solaris Cluster documentation on docs.sun.com.
Hope that helps,
Tim

Microsoft Failover Cluster Virtual Adapter

I have read the following blog about Microsoft Failover Cluster Virtual Adapter and have few questions.
http://blogs.technet.com/b/askcore/archive/2009/02/13/what-is-a-microsoft-failover-cluster-virtual-adapter-anyway.asp
How does this adapter choose the IP address? It seems that it is using 169.254 subnet address.
Can the IP address changed? If yes, how to change it in Windows 2008 R2?
What tool is used to show the kernel drivers? The blog shows a screenshot below the sentence The Cluster network driver (netft.sys) is a kernel mode driver and is started and stopped by the Cluster
Service.
If the physical NIC which has the same MAC address of the adapter is disabled, will that cause problem?
Thanks.

Hi PCSQL66,
Firstly, NetFT self-configures an APIPA adres and no manuel user config requireds. Then MAC adress is self-generated based on a hash of MAC address of the first enumerated (by NDIS) physical NIC in the clsuter node. You know Netft is a virtual network adapter.
And you cannot change it and you dont need to change.
You are right about MAC address conflict but mac address conflict detection and rersolution in Win2012.
I think what you want to see about kernel mode drivers or user mode etc you can use the sysinternal utility.
I want to say NDIS 6.2 is miniport virtual adaptor.

Setup Multiple WLE and groups on virtual IP addresses

I need to setup multiple instances of WLE in our Solaris development environment so each developer can have their own servers running without interferance from other developers. Concept is each developer manages their own ubb file and tmload's their version. I have multiple virtual IP addresses setup on the Sun box so each WLE will run 'on' different IP addresses.Comments? Will I have license issues?

hello,
you can implement this using the following oracle command line utilities.. crs_profile, crs_register, crs_setperm. i have done it several times myself .. here is an example..
as root user:
1. create the resource:
$CRS_HOME/bin/crs_profile -create rnora1.vip_dg -t application -a /appl/crs/bin/usrvip -o oi=eth5,ov=10.204.51.20,on=255.255.255.192 (mind that oi=<physical nic name>, oi=<new_vip>, on=<vip_subnet>. Of course the new vip should be in the same subnet as the physical nic.)
2. register the resource to the cluster:
$CRS_HOME/crs_register vip_dg
3. give permitions to the oracle user to handle the resource:
$CRS_HOME/bin/crs_setperm vip_dg -u user:oracle:r-x
then, executing crs_stat -t command you should see in the output the created resource "vip_dg"
if you want to have a second listener register to the cluster and listening on that vip you just created (as user anilkjha requested in previous post) the you can just run netca
in order to create for you the second listener resources and add them to the cluster as well..
mind that for some stupid reason netca do not see the second vip and by default he tries to create a second listener in the first vip. just ignore the errors-warnings and create the resource.
then manually edit the listener.ora file so that the new listener entries reflect to the second vip you had just created before..

Windows Network Load Balancing - Virtual MAC Address

Hi All,
I have environment that running 2 Exchange 2010 server with CASHT and join windows network load balancing as a node.
My question is,
If NLB service is restart, is it virtual MAC Address for NLB will change to new virtual MAC Address?
Thanks for response,
Best Regards,
Henry Stefanus

Hi Henry Stefanus,
The NLB work mechanism will not change whether what higher application we used and I am not very familiar with Exchange NLB architecture, may the following KB and article
may help you.
When you use the unicast method, all cluster hosts share an identical unicast MAC address. Network Load Balancing overwrites the original MAC address of the cluster adapter
with the unicast MAC address that is assigned to all the cluster hosts.
When you use the multicast method, each cluster host retains the original MAC address of the adapter. In addition to the original MAC address of the adapter, the adapter is
assigned a multicast MAC address, which is shared by all cluster hosts. The incoming client requests are sent to all cluster hosts by using the multicast MAC address.

Programs that require a network connection won't work because there is no virtual IP address available for this session.

Programs that require a network connection won't work because there is no virtual IP address available for this session. Per application IP virtualization is enabled.
There are in fact available IP address's within the dhcp scope. Before I dig to deep into root cause.. Could the problem be RDS CAL licensing running out, or isn't that not a symptom of my error message?

Hi,
Thank you for posting in Windows Server Forum.
As per my research, there is no any issue related to RDS CAL licensing. Prior to the issue which you are facing, there are some basic setting which need to configure.
Application Compatibility – Turn on Remote Desktop IP virtualization
Some applications require a unique IP address, which is by default logically not the case if the application is running on RD Session Host. To solve this issue, Remote Desktop IP Virtualization is introduced. With this setting you enable the IP virtualization
feature. When enabling this setting you need to specify if the virtual IP is provided per session or per program. When using per program you need to define the executable to which an IP address should be configured. Desktop IP virtualization also needs the
configuration of the next setting.
Application Compatibility – Select the network adapter to be used for Remote Desktop IP Virtualization
When you need to use Remote Desktop IP virtualization configuring this setting is mandatory. You need to specify the IP address of the Network Interface Card which should be used for this feature. Besides the IP address you need also to specify the network
mask using the slash notation, for example 192.168.77.201/24.
Application Compatibility – Do not use Remote Desktop Session Host server IP address when virtual IP address is not available

Virtual Column not allowed here Error

Hi All,
I am facing "Virtual Column not allowed here" Error when running a simple select statement. I have identified that if I am removing a primary key constraint and an index on top of month table which is used in the SQL solving this issue. But want to know the exact reason of this error. FYI I am having two indexes on Month_end_date_key (which is also a primary key) and Month_end_date. Could you please let me know the reason for this.
FYI I am not doing any insert,update deletion operations. I am using only the tables in the SQL not using any views.

I am trying to send an email from Lookout V6.6 using the Mailer object. I have an email address setup through GMAIL and have verified it works. Also, Lookout Mailer object is able to verify GMAIL server. I get the following error message when trying to send the email: "SMTP: invalid from address.

Another method is to use a SMTP relayer, we have deployed them in the past.

Virtual IP Addresses

Hi Everyone !
My weblogic server listens on a virtual IP address. When the HttpProxyServlet proxies to another weblogic server, it doesn't make the outgoing proxy using the virtual IP address. It uses the the actual IP address assigned to the unix box and not the virtual IP address my weblogic server listens to. This has been confirmed from the firewall logs.
This is important because the firewall requires source IP and destination IP in its rules.
Is there a way to force weblogic server to use the virtual IP address for outgoing calls/requests.
Thanks,
Eddie

Thanks for your response.
I can now see the different ip addresses assigned per session id. Is there a way I can get the thin client to display the ip address as per what I'm seeing in Application
and Services Logs/Microsoft/Windows/TerminalServices-TSAppSrv-TSVIP\Admin?
We have a plugin which looks for an rds session id's unique ip address. but due to the multiple ip addresses displaying. The plugin wont work.
is there a way I can get the ipconfig to show only the newly assigned ip address.
Thank you for your response, much appreciated.

Hi,
this may be a false/positive log record.
First check the services and applications on the effecting machine (NETSTAT -ANO) to see which connections the machine has established or tries to establish.
Check the machine against viruses and spyware.
if you don't find any viruses / spyware or "mysterious" connections, create a connection exception limit in the flood mitigation settings on your TMG Server:
