Should SCAN VIP and Listener jump among Nodes?

Oracle (GI and DB): 11.2.0.3 SE
OS: RHEL 5.6
I remember when I first tried scan several years ago (most likely with 11.2.0.1 EE), the SCAN VIP and Listeners jumps from node to node whenever a DB connection was established.
Recently, in a newly installed 2 node cluster running 11.2.0.3 SE, it seems the SCAN VIP and Listener stick to a single node unless during failover or requested with a command. As a result, a SCAN VIP and Listeners end up running on a single node after some failover testing.
Which is the designed behaviour? I understand they can direct connection requests to DB instance on other node. Just want to know whether they are supposed to jump?

Hi,
I have not tried it myself, but if you look at the crs profile on how SCANs are defined, they are set to DISPERSION.
# crsctl stat res ora.scan1.vip -p
NAME=ora.scan1.vip
TYPE=ora.scan_vip.type
START_DEPENDENCIES=hard(ora.net1.network) dispersion:active(type:ora.scan_vip.type) pullup(ora.net1.network)
...So they should not/never run on the same node, since the dispersion policy tells them differently.
However this dependency is checked at startup time, and not always during runtime. So if you do a lot of test, your szenario is possible.
Have you tried waiting a while, if this resolves the issue?
If they stay on the same node, I would open an SR, because then it does not follow the dispersion policy.

Sebastian

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!!

Why the scan lister and listener configure/start from GRID home why not from Oracle Home.

Hi
why the scan lister and listener configure/start from GRID home why not from Oracle Home.

> why the scan lister and listener configure/start from GRID home why not from Oracle Home.
Because Oracle says that's the way it has to be.
As @MohaAGOU said, starting in 11gR2, the Listeners (both SCAN and traditional) are now cluster resources. Let's start with the SCAN Listener. There are only 3 of them, even if you have 4 or more nodes in the cluster. If a node goes down and a SCAN Listener were running on it, Grid Infrastructure will relocate the SCAN Listener to a surviving node. Much easier to do this if the entire resource were in the GI home. Note that an instance cannot be relocated and it is running on a different home.
As for the traditional listener. The Listener itself won't be relocated during a node termination, but its VIP will.
Cheers,
Brian

Scan-vip running only on one RAC node

Hi ,
While setting up RAC11.2 on Centos 5.7 , I was getting this error during the grid installation:
PRCR-1079 : Failed to start resource ora.scan1.vip

I figured that the scan service is able to run only on one node at a time. When I stopped the service on rac1 and started it on rac2 the service is starting.
But I think for the grid installation the scan service has to simultaneously run on both the nodes.
How do I resolve it?
Any suggestions please.
PS - I am planning to try with the patch 11.0.2.3 but it will be a while till i get access to it.
Till then can someone suggest a workaround?

Hi Balazs Papp and onedbguru,
I was able to resolve that error by running the following command on rac2, now that part of the installer passed.
crsctl start res ora.scan1.vip
However the cluster verification utility is failing at the end of installer.
When I executed the below command, this is my output:

SCAN listeners and default listener all goes to 2nd node

I installed GRID/Oracle yesterday and I saw on the first node, there are scan-listener1,2 and on second node, it has scan-listner3.
This morning,I try to create db by dbca, and it give me a warning that there is no default listener on local node.
Then I checked, there is none any listener at all on local node:
ps -ef|grep tns
grid 31295 30685 0 13:47 pts/1 00:00:00 grep tns
but all on second node:
ps -ef|grep tns

grid 16959 1 0 06:22 ? 00:00:00 /u01/app/11.2.0/grid/bin/tnslsnr LISTENER_SCAN2 -inherit
How to explain this situation? How all the listener failed to second node?
WHere is the log I can check?

SCAN IP and all 2 VIP listner is unavailable for 1+ min when one node down

I have two redhat Linux nodes running the Oracle 11.2.0.3
Everything is OK except, when I powerdow one node (cold or soft reset). the VIP and SCAN lisnter stop working for 1+ minutes. (Using Navicat connection check, all connections are unavailabl for a while)
Is it normal? The problem is the application DB connection timeout is about 20 seconds.

Hi,
even though this sounds quite long (especially for a hard kill of the node, not a reboot), it does not matter if you configured your application correctly:
http://www.oracle.com/technetwork/products/clustering/overview/awm11gr2-130711.pdf
Since the application will move to the VIP/SCAN IP running on the second node after 3 sec (connection outbound timeout).
However failover of VIP and SCAN should be in seconds not minutes...
And it should not have an effect on all connections - just the ones going to that VIP/SCAN on that node.

Sebastian

Vip swing among nodes and able to it's node

Hi Experts,
We have a 4 nodes oracle 11.1 RAC server with 10g2 database. OS is redhat 5.1.
When I log into each node by vip, it alaway point to one fixed node (supporaced as D) after log in.
I could not log into A, B , C nodes.
I only can log into each node( A, B, C, D) by its pub IP. But I could log into each node by VIP before.
Also We have other 4 nodes the same initial RAC, both VIP and Pub IP can log into
each node too.
What kind of issue is about this issue?
How to fix it?
Thanks
Jim

You might want to check if all your cluster services are ok, because what you are saying indicates that something is wrong with 3 of your 4 nodes. Try 'crs_stat -t' to see if any resources are not available

RAC 11gR2 VIP and SCAN failover behavior

I tried to failover testing on 2 node 11gR2 RAC on Linux 5 X86-64 with configure in tnsnames.ora on client side (client side TAF configuration) with the following configuration
NVSDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dbrac-scan)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = NVSDB)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5)
The test scenario
1. Connect from client to RAC database , and test query with select * from dba_objects
2. Open new terminal and connect to instance in step 1 , then shutdown abort
3. I found that , the session in step 1 not failover to other node , and VIP and SCAN not failover to other node too
In my opinion session , VIP and SCAN should failover to other node.
Or is this the default behavior of VIP and SCAN on 11gR2 ??
Can anyone suggest me ?
Thankyou and Regards

user10139161 wrote:
3. I found that , the session in step 1 not failover to other node , Which client/driver did you use to try this? The reason I am asking is that TAF is not supported with jdbc:thin, so if you were trying this with sqldeveloper and the defaul driver that would be the expected behaviour
and VIP and SCAN not failover to other node tooThat is also expected. You only stopped the instance, there is no reason to relocatethe VIP. In your case, client could still connect to the listener running on this node, the listener would know of the second instance still being up and redirect all connection attempts there.
What you could try is rebooting the whole server, then you would see IPs being relocated.

Can SCAN VIPs also come back, when the node is Up after failover?

Hi,
Consider a two node cluster, as two SCAN vips are running on Node1 and one on Node2.
As,Node1 is down so the resources and the Node vip failovers to other node.
When the Node1 is back again, what about the SCAN VIPS they will also come back and work for Node1.
Thank you

Hello,
First of all answer of your question is YES.
Now Oracle suggest that we should use 3 SCAN VIPs (SCAN LISTENERs).
See this demo for your question:
I have 3 node RAC setup : HOST01 & HOST02
*# crsctl stat res -t*
As you can see currently SCAN VIPs are running on all the machines, now i am going to stop crs from HOST02 and see the status of SCAN VIPs:
From host02
# crsctl stop crs

WHY: Scan VIP does failover, but Scan Listener does not!

Hi,
I have a two node cluster based on 11.2.0.4 (no patches yet). When one node is down, the scan vip does failover to the other node, but however the scan listener does not:

Hi,
thank you, but this does not match to my problem:
- those socket files are owned by oracle:oinstall on both nodes, I deleted them to give it a try but no change
- I can start the LISTENER_SCAN2 on node 1 using lsnrctl when node 2 is down, but I cannot using crsctl and GI does not check it when I start the listener manually
- GI seems to be kind of confused about the state of the LISTENER_SCAN2 while node 2 is down (is already in the INTERMEDIATE state on server 'rzsolv236' vs. OFFLINE state in crsctl stat res -t)
see output below ...

What should have in equal tnsnames,ora and listener.ora?

Hi forum members again I'm very new in oracle, and I'm trying to create a sucessfull net service name, using oracle net configuration assitant, but when I try to test it I got this error, .***"""ORA-12514: TNS:listener does not currently know of service requested in connect descriptor."""*** And I have read that tnsnames.ora and listener.ora should have some parameters in common, but exactly I don't know, Do you know what parameters should be? or The ORA-12514 problem , doesn't have relation with the tnsnames.ora and listener files?, If doesn't wich is the reason of this message?
By the way I put what contain these files:
---------------------------------------------------------------------------listener.ora

(ORACLE_HOME = /opt/oracle/product/10.1.0.3)
(SID_NAME = oracle)
LISTENER =

By the way what must be the username and the pasword that ask the ORACLE CONFIGURATION ASSINTANT to test the net service name? Must be the user name and password of the system user?
Thanks in advance

OK, here we go ... extra long as I intend to bookmark this and make reference, as this is a very common question ... skip to the bottom if you want my guess to the solution.
Oracle Net Services (formerly SQL*Net, Net8, Oracle Networking) has two parts - the client and the server side. I'll discuss the server first, then the client.
1) Server, and specifically Listener:
The Oracle Listener is a monitor that listens for Oracle service requests on one or more ports. Usually this is on TCP/IP port 1521. When it gets an Oracle request from any network client, it checks whether it's in the list of Oracle Services for which it is monitoring. If found, it will contact that service, request a connection for the client, tell the service and client where and how to connect, and get itself out of the loop.
Notes:
a) It can listen on behalf of any number of services;
b) A service can be a database instance, an EPG service (the DBMS_EPG is the replacement for Apache in the database in 10gR2), an external job, etc;
c) One listener can listen on behalf of multiple database instances;
d) The services can be listed in the LISTENER.ORA or they can self-register;
e) If databases self-register, they use the initialization parameter LOCAL_LISTENER
f) If self-registering, the listener should be up before the database
g) Shutting down the listener will stop future connections, but has no impact on existing ones.
One frequent point of confusion - a connection request on the local machine may loop out to the network and contact the listener, or it may bypass the listener entirely and use a bequeath adapter. The 'beq' connection is the 'normal' connection by "sqlplus / as sysdba" or "sqlplus system/manager" on the local machine (note that no @instance was used ... in *nix, that is derived from the $ORACLE_SID environment variable)
In your listener.ora, you specify global_dbname=oracle.gentoo and sid_name=oracle. I assume therefore you can find an initoracle.ora or spfileoracle.ora somewhere on your system.
2) Client:
A client that wants to connect to an Oracle service uses the client side of the Oracle Net Services. The definition of client includes: any Oracle client utiltiy (SQLPlus, SQLLoad, Forms, Reports, etc.); an Oracle database instance that wants to make a external procedure call or a dblink; third party tools such as ODBC and JDBC.
In SQL*Net version 1 the connection was made by specifying the target in the connect string ("user/password@host:listener_port:sid") and that is also used these days by many JDBC drivers, especially the Oracle Thin JDBC driver. Oracle's Easy connection mechanism uses a similar variant.
Since SQL*Net Version 2, Oracle has supported the concept of alias translation. Basically it's very similar in concept to DNS - give it the name of the service and tell it where to find the translation table. The translation tables include TNSNAMES.ORA, ONAMES servers (deprecated in 10g), LDAP usng Oracle's OiD. The choice of translation table, and alternate order if the lookup fails in one, is stored in the SQLNET.ORA (if one exists).
Assuming TNSNAMES.ORA, the chain of events is:
- get the alias to look up (in your case NORACLE);
- if the SQLNET.ORA has a DEFAULT_DOMAIN setting, (often =WORLD) append a dot and that value to the alias;
- go to the TNANSMES.ORA file pointed by the TNS_ADMIN variable (environment or registry), or (if not set) the one in the $ORACLE_HOME/network/admin directory;
- look up the first occurance of the alias;
- if found, use the protocol specified to request a connection to the host, usin DNS to unravel the host to an IP address if necessary (in your case TCP/IP, to TUX) ;
- if host connection if made, connect to the listener that is configured for that port (in your case 1521);
- if listener is there, ask it for connection to the service (in your case, you are asking for instance 'noracle');
i if the listener knowwss about the service, it will hand off the request.
Your problem appears to be asking for instance 'noracle' in the tnsnames but listeneing for 'oracle' at the listener. Of course, I can not see any auto-registered instances which you would get from "lsnrctl status" on the server.

Hello,s
First of all, check the status of all resources by using crs_stat -t
Check if your VIP resource is indeed up and running on the node where you want to start the listener. As listener is depending upon this VIP address, it is needed to be up on the node where listener is configured. If this is the case then relocate the vip back to the system by using either of the following commands
1. crs_relocate <vip_resource_name>
OR
2. srvctl start nodeapps -n <hostname>
listener should be automatically up once crs relocates back the vip to the system.
If vip is already running fine on the system then check for your listener configuration as you check in normal systems.

We have not available the DNS Server for used to SCAN feature of Oracle11g r2 GRID/RAC.
we have successfully deployed the the setup using scan-vip in /etc/host in our production site.
we want to used the Oracle11g r2 Grid/RAC as Oracle10g r2 RAC/Oracle11g r1 RAC(VIP Failover)
plz find the default configurations of my setup.

plz suggest the provide the step to configure the listener.ora and tnsnames.ora for use the Oracle11g r2 Grid/RAC to use as
VIP failover instead of SCAN-VIP failover.

ACE30 - PING to VIP and Client side SVI not working

Hi Guys,
Having setup the ACE30 based on the configuration guides, I've been able to get basic load balancing working, probes, stickness etc. However in testing connectivty, I've noticed that from the real server on the backend I cannot seem to PING:
1. The VIP for the web service that the server is a part of
2. The Client side SVI
I'd like this to work to ensure full connectivity.
I've applied ACLs to the Client side SVI (on the ACE) to allow this in both directions, and also removed any ACLs attached to the client side SVI on the MSFC where the subnet is actually homed. However I just cannot seem to PING the Client side SVI on the ACE, or the VIP. Trying to understand if this is normal behavior.
Have inserted my config below for completeness.

To ping your VIP of the webserver, you should apple the service-policy input command on VLAN 186 too. Currently the VIP only listens on VLAN 11. For the SVI i think that was forbidden by security reason, but i cant remember anymore. Maybe you just need to put the management policy on the interface VLAN 186. If it dont work, then my first guess was right

Should SCAN VIP and Listener jump among Nodes?
