RAC connection problem with interconnect NIC failure

We have an 11g 2-node test RAC setup on RHEL 4 that is configured to have no load balancing (client or server), with Node2 existing as a failover node only. Connection and vip failover works fine in most situations (public interface fail, node fail, cable pull, node 2 interconnect fail, interconnect switch fail etc etc).
When the node1 interconnect card failure is emulated (ifdown eth1):
node2 gets evicted and reboots
failover of existing connections occurs
VIP from node2 is relocated to node1
However new connection attempts from clients and the server receive a ORA-12541: TNS:no listener message.
The basis of this is the issue that in the event of an interconnect failure, the lowest number node is supposed to survive - it looks like this includes the situation where the lowest number node has a failed interconnect NIC; ie it has a hardware fault.
I checked this with Oracle via an iTAR quite some time ago (under 10g) and they eventually confirmed that this eviction of the healthy 2nd node is correct behaviour. In 10g, this situation would result in the remaining instance failing due to the unavailable NIC, however I did not get the chance to fully test and resolve this with Oracle.
In 11g, the alert log continuously reports the NIC's unavailability. The instance remains up, but new connections cannot be established. If the NIC is re-enabled then new connections are able to be established. At all times, srvctl status nodeapps on the surviving node and lsnrtcl show that the listener is functional.
The alert log reports the following, regarding a failed W000 or M000 process:
ospid 13165: network interface with IP address 192.168.1.1 no longer operational
requested interface 19.2.168.1.1 not found. Check output from ifconfig command
ORA-603 : opidrv aborting process W000 ospid (16474_2083223480)
Process W000 died, see its trace file
The W000 trace file refers to an Invalid IP Address 192.168.1.1 (the interconnect ip address) obviously the source of the process dying.
Finally, if I restart the remaining instance via srvctl stop/start instance with the NIC still unavailable, the instance will allow new connections and does not report the failures of the W000/M000 process or appear to care about the failed NIC.
Before I go down the iTAR path or start posting details of the configuration, has anyone else experienced/resolved this, or can anyone else test it out?
Thanks for any input,
Gavin

Thanks for your reply.
There is no NIC bonding - the interconnect is a single, dedicated Gigabit link connected via a dedicated switch: plenty of bandwidth.
I know that providing interconnect NIC redundancy would provide a fallback position on this (although how far do you go: redundant interconnect switches as well?), and that remains an option.
However that's not the point. RAC does not require a redundant interconnect - as a high-availability solution it should inherently provide a failover position that continues to provide an available instance, as it does for all other component failures.
Unless I've made a mistake in the configuration (which is very possible, but all the other successful failover scenarios suggest I haven't), then this could be a scenario that renders a 2-node cluster unavailable to new connections.

RAC, Interconnect and CloudControl (a nice to have problem :-) )

Hi,
someone has changed the networkmask for one interconnect interface (eth3). eth3 is up an running, the interconnect ip-address move to the second interconnect interface here eth1. Everything is working fine, and after network is changed back the eth3 interface get his interconnect ip-address and all is fine. But there was no incident in CloudControl no warning that something is going wrong. A user defined metric on GV_$CLUSTER_INTERCONNECTS is no solution, the view shows old values. cluyfy is useful in this case.
best regards
Thomas

Hi,
I think two options
cluvfy and oifcfg to check the network configuration

The Sun Cluster 3.2 Release team is pleased to announce a Beta Refresh release. This release is based on our latest and greatest build of Sun Cluster 3.2, build 70, which is close to the final Revenue Release build of the product.
To apply for the Sun Cluster 3.2 Beta program, please visit:
https://feedbackprograms.sun.com/callout/default.html?callid=%7B11B4E37C-D608-433B-AF69-07F6CD714AA1%7D
or contact Eric Redmond <[email protected]>.
New Features in Sun Cluster 3.2
Ease of use
* New Sun Cluster Object Oriented Command Set
* Oracle RAC 10g improved integration and administration
* Agent configuration wizards
* Resources monitoring suspend
* Flexible private interconnect IP address scheme
Availability
* Extended flexibility for fencing protocol
* Disk path failure handling
* Quorum Server
* Cluster support for SMF services
Flexibility

* DNS
* NFS V3
* Java Enterprise System 2005Q4: Application Server, Web Server, Message Queue, HADB

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

Rsh in solaris

hi guys
we have moved our apps and db servers physically
my solaris admin had earlier made a shell script for daily backup of prod system. since we have 2 node configuration,he is calling the second node from 1 st node to stop the apps services. however the rsh command is giving timeout.
he is using the following line in script
"rsh prdap -n '/tmp/stopapp.sh >/dev/null 2>&1 </dev/null &'"
I want to know where is prdap defined as alias for the ap server.
more hosts --
127.0.0.1 localhost
10.224.8.142 faprdap.sog.com faprdap
192.168.0.2 prdap
on faprdap.sog.com
more .rhosts
faprddb.sog.com root
prddb root
However, the apps server is faprdap.I was wondering y he is calling the "prdap" and it was working fine.
Any help would be appreciated
Anmol
...

As I understand from your post:
- Application node hostname: prdap
- Application node IP Address: 192.168.0.2
- Database node hostname: prddb
- Database node IP Address: Unknown
Your DBA is calling "stopapp.sh" script from the database node to stop the application services using "rsh prdap -n '/tmp/stopapp.sh >/dev/null 2>&1 </dev/null &'"
faprdap, and faprddb are private interconnect hostnames (addresses) for the application node and the database node respectively which are used for the cluster purpose.

UDLM rac-udlm-rs failing to come online

Hi all,
I'm setting up a zonecluster that will be running RAC. This has gone well, up to the point where, using clsetup, I attempt to create the rac-framework-rg (and associated rac-udlm-rs, rac-framework-rs).
In attempting to create the resourcegroup, the rac-udlm-rs fails to come online, causing the rest of the framework to fail.
The error in the logfile for UDLM (/var/cluster/ucmm/dlm_<zone>/logs/dlm.log is:
CONNECT ERROR: 'Invalid argument', family=0, port=6009, in=0.0.0.0
This repeats 5 times per second on both zonecluster nodes. regularly the error changes port (i.e. it cycles through the ports).
I've tried rebuilding the zonecluster, to no avail. I am at a loss as to what the error might be, or where to start looking, since there is no evidence anyone has ever hit this error before.
Any suggestions on where to look and what I can try to fix this is will be appreciated.
Possibly related, or even the cause, is that the zonecluster has been configured with:
add net
address=xxx.xxx.xxx.xxx
end
at the zonecluster level, but these addresses are not showing up under 'ifconfig -a'. Maybe I'm misunderstanding how they are used, and when they should show up though.
Some notes:
the zonecluster in all other respects seems fine - I have QFS resources configured and these appear to successfully work in all circumstances.
the ORCLudlm package is installed (the one that comes with Oracle 11.2.0.3)

Right, in case this helps someone else in future:
I found the problem. In a fully working zonecluster configuration the /etc/nsswitch.conf file includes these lines:
hosts: cluster files
netmasks: cluster files
but for sad, sad, reasons on the system I was setting up this file had:
hosts: files
netmasks: files
and you know what, this allows you to go:
ping clusternode1-priv
and this does a lookup and resolves correctly. Now, if this doesn't resolve correctly, basically the UDLM daemon cannot communicate with the other cluster nodes, because it must do a nameserver lookup on clusternode1-priv internally.
So, in essence, make sure your nsswitch.conf file looks up the cluster first for hostname lookups.
This issue shows itself if you do a traceroute to the IP of the other cluster node (from one of the zonecluster nodes) using the private interconnect IP address. In a working system it'll show the name (clusternode1-priv). In a non-working system it shows the IP only.

Question about 'hosts: cluster' entry in /etc/nsswitch.conf

Hi~
my system have "hosts: cluster files dns" entry in /etc/nsswitch.conf.
I know 'files' to see the '/etc/hosts'.
I want to know that 'cluster' to see 'what file'.
Thanks,

'cluster' denotes internal lookups, i.e. no file on the file system. If I recall correctly, it allows the system to look up the cluster interconnect private addresses.

Step by Step RAC 11GR2 with Grid Infrastructure on Solaris installation

Y'ello All,
Please I need documentation for RAC 11GR2 with Grid Infrastructure on Solaris installation urgently.
Thany you very much for your support
BR,

What type of shared storage will you be using?
Properly configure DNS
Properly configure /etc/hosts files
Properly configure SCAN
Properly configure SHARED storage (Preferably ASM - "raw" devices) - make sure you partition the disk devices to "skip" the first 1MB of the device)
BEFORE installation, confirm grid-owner and oracle-rdbms-owner can read AND write to these shared devices from ALL nodes. Permissions must be set to <grid-owner:<grid+oracle shared group> (grid:oinstall where oracle is also in the oinstall group)
Properly configure ssh password-less connections for both GRID-owner AND oracle-rdbms-owner.
IP addresses required
3 SCAN addresses that point to myhost-scan.mydomain.tld in a round-robin fashion
PER NODE:
1 public IP address
1 virtual IP address
1 interconnect IP address should be iin /etc/hosts ONLY - Non-routable and not reachable via the public interface. DO NOT use CROSSOVER cable.
Interconnect should be on a DEDICATED INTERCONNECT switch.
As for the SHARED storage, the LUNS/Devices can be "carved" out on your SAN by your SAN admin. MAKE SURE that ALL devices in a given diskgroup are EQUAL size. (ie - DATA000=250GB/each, DATA001 500GB/each etc)
The installation guide gives a lot of directions on PRE-REQUISITES. Follow them. And remember, since you are new to this, you may install this several times before you get it the way you need it to be. Even installing MANY RAC clusters on multiple platforms, I still install it 2-3 times. Generally because the SA has forgotten some pre-req step.

Doubt in ID Note 1373350.1

Hi,
In the note what does this point mean? and how do I check it?
4) SCAN should have the netmask already used by public interface.Should it be possible to ping the VIP also?
Please explain.

Please explain.So, you are reading a doc in MOS, my question is why? what is broke that you think you need to be looking at that document. What problem are you trying to solve?
If your cluster is functioning properly you should have already configured this before you started your installation. As you may have determined, you will not be able to ping the VIP until you have configured it and it has been added to the public interface.
Example
eth0:0 public-ip-address
eth0:1 vip-ip-address
eth0:2 scan-ip-address (if it is running on this node)
eth{n} interconnect-ip-address (Note: that the device names should be the SAME device on all nodes for both public and private interfaces - see the docs)
Start here:
http://docs.oracle.com/cd/E14072_01/rac.112/e10717/intro.htm
It might also be very helpful if you were to take a System/Network Admin class so you can start to see how things work together. If you can't take a class, buy a book and start reading and testing and testing and testing and testing and testing and testing and testing and testing and testing and testing and testing. If you completely destroy/break it, erase, re-install and start again. This is the BEST way to learn. Don't skip steps in the installation, Don't try to "do it better". Do what the instructions say.
BTW, it is about time that you started actually reading the documentation - quit "doubting" and just do what the docs say. I have noticed that you have been posting daily using the forum to teach you what you should be learning on your own - like the rest of us did when we first started out. We cannot always be your baby-sitter. You may think this to be harsh, but, in the end, you will see that this is the best approach for you to get the knowledge necessary to get and keep a DBA job without destroying your client/employers databases.

Need procedure to change ip address on private interconnect in 11.2.0.3

Could someone please send me the procedure to change the ip address of the private interconnect in 11gr2 rac (11.2.0.3)
The interconnect has been configured using the default HAIP resource during installation of a 2 node cluster on the aix 6.1 platform. I have searched metalink but cannot find a doc with the procedure to make the ip address change.
The sys admins gave us an ip address on the wrong subnet so now we have to change the ip address of the en1 interface.
If anyone has steps in terms of shutting down the clusterware and correct order to make changes this would be very much appreciated.
Thanks.

Thanks, I seen this one also but I was just hoping to see some official documentation from oracle on this topic. I searched metalink and there is a doc id called
"Grid infrastructure everything you need to know" but it does not speak to this configuration change or even how to disable the clusterware in the event that you need to perform maintenance and do not want the clusterware to automatically come online.
Although I love google too... but If there are any official documentation on this topic I would really appreciate to know where it can be found?
Thanks.

Rebooting fabric interconnect and mac addresses

I rebooted the subordinate and noticed that I lose only one ping on a vm and saw that mac address show up in the primary.
After the subordinate came back online, I did a show mac address table on the subordinate and noticed that a bunch of mac addresses showed back on the subordinate.
how does ucs know what mac address to use for the subordinate or primary when the subordinate comes back online?
the vm that i was pinging was initially on subordinate but after the reboot, it was on the primary.
but other mac addresses are already showing on the subordinate right after the reboot

2 ISPs with addresses /32 and PPtP Server onboard of Cisco 3825

First of all, excuse me for my bad English, it's not my native language.
A couple of years ago our company changed our central router Cisco 1841 with more powerfull 3825 ISR.
Here is show ver
Cisco IOS Software, 3800 Software (C3825-ADVENTERPRISEK9-M), Version 12.4(24)T7
This Cisco 3825 contains 2 DIMMs - 256Mb and 512 Mb of RAM onboard.
Now it works with 2 ISPs (take a glance on pdf picture http://www.intelcom-ug.ru/scheme.pdf or in the attached file). We're using the failover scheme, the ISP1 with statically assigned IP address 85.20.20.20/32 (Dialer 1) is used as Backup link. The ISP2 L2TP link is main.
Now our authorities organize the remote office with Cisco 1841. And we face with the problem, we cannot connect via PPtP from anywhere to the 85.20.20.20/32 (Dialer 1). And we need some help or advise. The config of Cisco 3825 is like this:

Okay, you are not going to be able to do this using the interconnect between the switch and the router. The issue is -
1) if you make the interconnect a L2 trunk then you would have subinterfaces on the router interface connecting to the switch. But you cannot have multiple interfaces on the router configured from the same IP range so it won't work ie. you would need a subinterface using the same IP range as one of the other interfaces
2) if you make the interconnect L3 as you have then you cannot route to the same subnet ie. think of it as two separate devices, a L3 switch and a router. You connect the L3 switch to the router using a L3 connection.
On the switch you then configure a client with a public IP and on another interface on the router ie. not the interface used to connect to the switch, you use the same public IP range.
You cannot then route from the client to that other interface because you don't route to the same IP subnet and the client and the other interface are separated by a different IP subnet.
So neither will work. The L3 switch is usually used where you have multiple vlans/IP subnets and you create L3 vlan interfaces for these on the switch and then you route to other subnets that are reachable from the router, whether these are directly connected subnets or remote networks.
But you aren't doing that.
The only way i could see you doing what you need is to not configure the interconnect at all and instead run cables from the relevant router interfaces to the switch. Then you could configure vlans on the switch and have them route via the physical router interface.
The switch is then only acting as a L2 switch and all L3 is done on the router.
One thing i should say is i have never used the switch module this way so i can't guarantee it will work although i can't see why it wouldn't.

Contacts and Mac OS Address Book won't sync anymore

I have an iPod touch, 2nd generation, with iOS 4.2.1, which has worked perfectly well for years.
Since I got an iPad 2 with iOS 5.0.1, and iTunes 10.5.1, and set up iCloud, and synced the iPad to my Mac, now my iPod touch will no longer sync any address book entries between iOS Contacts and Mac OS X 10.7.2 Lion's Address Book.
I've tried restoring the iPod touch to its factory-fresh setting and syncing with the Mac. I've tried rebuilding the Mac OS Address Book index, and repairing permissions on Mac OS X. Nothing seems to help.
Another clue is that the iPod touch Contacts stopped syncing at 512 Contact entries, while the Mac's Address Book had 521 entries. I think 512 is a suspicious number; is it an upper limit on entries that sync with iTunes and Address Book?
Any help would be appreciated.

The messaget is correct, that is, your iCloud calendar will no longer be on your Mac as long as you are signed out of iCloud. Your calendars will still be on you iPhone and on iCloud. After syncing your contacts to your iTouch, you then sign back into iCloud on your Mac and everything will be back as it was before you signed out. I did it on my Mac and have all my calendars and contacts as well as my wife's iTouch has all calendars and contacts.
You seem to be concerned about losing data, which is a valid concern. Do you back up your Mac using Time Machine? It is a great resource installed on the Mac to assure that if you commit any errors that resutls in the loss of data, then you can easlily restore it via Time Machine. If you have not been backing up your Mac then consider doing it. The Apple Store sales personnel recommended to me the LaCie Storage devices since they easily interconnect with the Mac. A Google search will find them at competitive prices as compard to what Apple charges. I am so paranoid about losing data that I have three separate 1TB LaCie drives backing up my Mac. I will be installing a forth as a network backup drive for my wife's Mac and my MacBook Air.

TS1646 I live in a foreign country and would like to use my US credit card (which has my current foreign address) to make purchase in the US App Store. How do I do this?

I live in Japan but I would like to use my US credit card to make purchases in the US Store.
I had no problems with this previously, but I recently informed my US bank of my Japanese address and changed it (had to).
There is no way to input my Japanese address (so that it matches the bank information) in the fields for the US App Store (which has no foreign country fields, you are limited to having to fill in the US state field, flags me for phone number area code differences, etc.).
When I hit the change country button: A) It took me to the Japanese App Store; B) I could not use my US credit card there (despite my Japanese address).
Yes, I may want to make purchases in the Japanese App Store in the future (I am bilingual), but the selections are different depending on the country.
Now I can make purchases in neither country.
I want to make purchases in the US Store from Japan.
Help! I feel like I am getting punished for being global. (The world should be getting smaller, more interconnected, and more convenient with the Internet --- not the opposite!)

Well, I can certainly understand the licensing argument if I were using a Japanese credit card with a Japanse address and making a purchase with Japanese yen from the US Store from Japan.
When I am making a purchase with US card from the US store with US dollars, the argument becomes a bit suspect (I know it is Apple's, not your argument).
it is just kind of a paradoxical situation and I am hoping Apple will offer some sort of solution. We can always hoe, right?
Thank you for your reply.

Crs Not Starting _ private Interconnect Down

Hello All,
I Have Installed 2 node 10g R2(10.2.0.1) RAC on Solaris 10 T2000 Machines. Yesterday my Second Node Crs gone down. I tried to start it but it didn't start. Then i checked that Private IP (interconnect) is not Pinging from both the node. But Node 1 was up and working so my Users Can Connect to It.
But Today morning I see that Crs on node 1aslo goes down .
Is this is problem of private interconnect.? My network guys are trying to up Private Interconnect.
If Private Interconnect is down, why node 1 goes down after few hours. i think private interconnect is for interconnect with node 2 but node 2 is down .
Previously My interconnect was connected with cross cables now i have asked them to connect them through switch.
Help me Out.
Regards,
Pankaj.

Even we are planning to do the same.Please share your experienceHope you have done this before - moving to switch
(Update for record id(s): 105681546)
QUESTION
========
1.Will the database and the Clusterware need to be shutdown etc?
2.Will our ip addresses need to be reconfigured?
3.Are there any steps that need to be carried out before unplugging the CROSS CABLE
and after the interconnect is connected to the switch...?
ANSWER
======
1. Yes, you have to stop CRS on each node.
2. No, not required.Provided you are planning to use same ip addresses.
3. Steps:
a. Stop CRS on each node. "crsctl stop crs"
b. Replace the crossover cable with switch.
c. Start the CRS on each node. "crsctl start crs"
Even we are planning to do the same.Please share your experienceFollowed by the above answers from Customer Support, It went smooth, we stopped all the services, and with both the nodes reboot.
