VIP network of RAC are on Node 2 Only

Hello,
This is related to this thread: https://forums.oracle.com/forums/thread.jspa?messageID=10817046#10817046, which is (as of writing) is still unresolved.
Is it normal to have the VIP eth are on the one node only?
Below is the result of ifconfig on Node 2:

192.168.216.45 is the VIP of Node 1, and 192.168.216.46 is the VIP of Node 2.
When the system starts up, both nodes have the eth0: 1 network. But after sometime, it seems to me that the "virtual network cards" (I do not know the right term), are being transferred between two nodes. And when that happens, either the listener of node 1, or the listener of node 2, or both are on "OFFLINE" status..
Our data import and loading activity are greatly affected by this issue, and we are now really far from schedule.
Please help.
Thanks.

Hi,
unfortunately you did not mention which Oracle version this is.
It seems your public network check is failing, hence the VIP gets relocated to the other node (where it still seems to be o.k.).
Depending on the used version, the VIP will not fallback by itself.
Why does the public network check fail?
Again there are different mechanism used per Oracle DB version.
Normally it indicates a problem with a network card, but since this is happening on both nodes, I more likely suggest, that you have a problem with the gateway (that it is temporarily not reachable), resulting in the failure of the VIP.

Thanks. This is actually related to my post here: Listener Suddenly Stops (Oracle DB 10g R2 RAC on VMWare)
Please find time to read that, maybe you can see the details that you need and maybe from there you can suggest.
Thank you very much for the help. :)

How to failover SCAN VIP and SCAN Listener from one node to another?

Environment:
O.S : HP-UX B.11.31 U ia64
RDBMS: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
It is a 2 Node RAC.
Question:
How to failover the SCAN VIP and SCAN LISTENER running on node 1 to node 2?
What is the relation between standard LISTENER and SCAN LISTENER ?
Why do we need LISTENER, when we have SCAN LISTENER ?
When I tried with SRCVTL STOP LISTENER , I thought the SCAN LISTENER adn SCAN IP will failover, but it did not?
Also please clarify if I use SRVCTL RELOCATE SCAN -i 1 -n Node1
Actalluy I am trying that by moving the SCAN listeners so that when I do PSU 7 patching on 1 node, no incoming attempt to connect will spawn
a process and thereby opening files in $ORACLE_HOME (which would prevent the patch from occurring)
Please clarify my queries.
Thanks, Sivaprasad.S

Hi Sivaprasad,
1. The following link will help you for SCAN VIP and SCAN LISTENER failover from 1 node to another.
http://heliosguneserol.wordpress.com/2012/10/19/how-to-relocate-scan_listener-from-one-node-to-another-node-on-rac-system/
http://oracledbabay.blogspot.co.uk/2013/05/steps-to-change-scan-ip-address-in.html
2. The Standard LISTENER is specific for particular node for which it is running. It cannot be relocated as its specific for the node its running. SCAN listeners are not replacements for the node listeners.A new set of cluster processes called scan listeners will run on three nodes in a cluster (or all nodes if there are less than 3). If you have more than three nodes, regardless of the number of nodes you have, there will be at most three scan listeners. So no relation for standard LISTENER and SCAN LISTENER.
3. Hmmm. let me put it in easy way for this question. All the RAC services like, asm, db , services, nodeapps registers with this SCAN_LISTENER. So if any of these services (asm, db , services, nodeapps) got down/not running, the SCAN_LISTENER will know the down status, and if any client requests to access the node/service which is down, the SCAN_LISTENER will redirect the client request to the least loaded node. So here all these process will happen without the knowledge of client. And As usual the standard LISTENER looks only for incoming request to connect with the database. So we need both LISTENER and SCAN LISTENER.
4. If you provide SRCVTL STOP LISTENER, it stops the default listener on the specified node_name, or the listeners represented in a given list of listener names, that are registered with Oracle Clusterware on the given node. No failover will happen under this case.
5. Yes you can relocate if you want to relocate the scan.
Hope this helps!!

VIP configuration in RAC

Hi All,
Please can I know which IP address is allocated to VIP in RAC.
like for SCAN
The IP addresses must be on the same subnet as your default public network in the cluster.
Thanks

You can see the VIP names with the following command:
srvctl status vip -n node_name
Repeat for each node. This will tell you the VIP names. You can use nslookup to translate to the IP addresses if needed.
Cheers,
Brian

Using the network load balancing from the nodes itself

I have installed a 2 node Sun Cluster 3.2, configured a shared ip resource and attached to it a scalable network aware resource working on the two nodes. I have crashed the process on one of the node in such a way that the cluster could not restart it again
In this status I tried to open a connection from another server and the load balancer always sent the traffic to the node that was up which is as expected...
If I try to open a connection from the node on which the process is failed then I get a connection refused meaning that the load balancer is not working in this circumstance.
Is this a bug/ a mis-configuration/ or just an inherent cluster problem.
Is there a solution to this issue?
Regards
Daniel

To answer your first question, no, there isn't anything you can do.
Here is what my colleague suggested while I was away:
Zone-clusters scalable services still require shared-IP zones, which means requests from one app to another would still bounce back due to loopback. Probably wouldn't help here.
They could isolate the services that must talk to other services into their own failover group on exclusive-IP zones. Other services can be setup as originally planned. But maybe there are too many such "dependent services" for this to be useful. Also, each failover service must have its own IP address.
Finally, can these web services be configured so that it tries multiple addresses. In that case, if the shared address foo for service X bounces back (due to X having crashed on the local node), the app itself would retry with address bar for service X? This allows for uniform configuration across all services, namely:
    - try shared address
    - try node 1's own address (either public or clusternode1-priv)
    - try node 2's own address
You can fine tune it so that configurations on node 1 only use node 2's address as backup, and vice versa. I don't know if that is any help.
As for your second question, the answer is that Solaris Container Clusters allow for consolidation and isolation of clusters onto a single set of nodes. Normal containers don't really allow you to consolidate complete clusters in quite the same way. See http://www.sun.com/offers/details/820-7351.html for more.

RAC on two nodes

Hi,
Need to implement Oracle RAC on two nodes.I am trying it first time so need some basic advice from you all regarding the basic requirements for installing RAC.
Are there any more softwares,other than Oracle11g setup, needed for installation?
What are the basic things I should keep in mind before installing RAC.
thanx

Are there any more softwares,other than Oracle11g setup, needed for installation?On Linux, you need a certified distro. When installing Grid Infrastructure, it will verify s/w components and lists the ones it need (suh as libaio, gnu c compiler, etc). yum install fixes that (on RHEL-based distros).
What are the basic things I should keep in mind before installing RAC.RAC is only ever as good as the h/w infrastructure it runs on. Specifically the I/O fabric layer and the Interconnect layer. If these are shoddy, not redundant, slow ito b/w, slow ito of latency, then you WILL have a RAC that fails to perform, fails to scale, and is unable to provide high availability and redundancy.

No.
Any problem connecting your iPhone to any other wi-fi network besides your own?

Who can shed some light on my ongoing connection problem.
After upgrading my iPad Air with IOS 7.06, I could no longer connect to the internet.
I have 2 MacBooks Air, 1 ipad mini and one iPhone 4S running on the same network, and they are all connected to the net and function well.
So I cleaned up the ipad completely, installed the latest firmware and reinstalled my apps : no connection.
I tried all things of resets and forgets. No result.
I have been fondling with my Airport Extreme 5 , but that did not help much.
This morning I went to a neighbor , hooked my ipad air on his network, typed the password and the thing all worked fine.
I have tried to connect the ipad air as an ethernet client, but that did not work. „Not enough power“ was the statement
Ideas anyone ?

Yes I tried this manyfold. But did not work. Reading on, I took Tesserac's advice. Shut down router and computer.
Start router after 15 minutes and wait another 10 minutes before starting the computer.
Et voila.... everything is back in working order,

CRS & RAC with 3 node

Hi EveryBody,
I am planing to install the Rac in my home, i mentioned the following information below.
i am using 3 system with windows 2000 server, i wan to install the oracle 10gR1 RAC.
my question is, for all nodes they need to install the CRS software ???? or one system is enough, and the same time what about the rac software, its enogh to install in one node or install in all node????
senthil

All nodes will will connected to each other with private IPs.......and you just need to install Clussterware and RAC from one node and add those nodes in your installtion. Oracle will install everything on its own on other nodes.
Hope this helps
Luck

Installation CDs : which network card drivers are included ?

Hello,
I intend to install Arch on a laptop with Broadcom and Atheros network cards (LAN and Wifi).
I would like to check which network card drivers are present on the Arch installation CDs to check compliance with this laptop.
Where can grab this info ?
Thanks.

Thanks for attention.
The network cards present on my laptop (Acer Aspire 4750) are :
Network controller: Atheros Communications Inc. AR9287 Wireless Network Adapter (PC-Express) (rev 01)
Ethernet controller: Broadcom Corporation NetLink BCM57785 Gigabit Ethernet PCIe (rev 10)
I would like to check if the needed drivers (one or both) are included in the installations CDs (netinstall / core).

Can't connect computers to printer (b210) via network because there are "other networks"

I can't connect computers to printer (b210) via network because there are "other networks matching your network name". This makes no sense at all. I have several Apple devices (iPhone, iPad, iMac) all with the latest software. The printer works fine when using the USB connection to my iMac. Nothing I do seems to solve this problem (rebooting, re-configuring, etc.). Help.

Hi Cgold,
If there are other networks matching your network name, then the printer will have issues connecting when you run the wireless setup wizard.
However, there are other options:
If your router supports 'Wi-Fi Protected Setup' with either a button to push on the router, or a pin to enter, you can choose that connection option under the wireless menu on your printer.
or
Change the network name that your router is broadcasting within the web page of your router (NOTE-this would force you to re-join all wireless devices back to the new network name you have created).
If I have solved your issue, please feel free to provide kudos and make sure you mark this thread as solution provided!
