VIP Failover Testing
Hello,
Am new to Oracle RAC. We have a 2 node 11gR2 Cluster and we are in the process of doing some failover testing. For database deployments we use an internal third part tool called the deployer which has tokens for DB configurations and the DBHost token in the deployer has the Hostname for either Node 1 or Node 2. In this way we are not actually utilising the HA feature because the connection is either to Node1 or Node 2 and if something happens to either the deployment cannot connect to the database on the respective Node which treats as a single Node instead of a Cluster.
Instead of mentioning the DBHost value to point to the Physical Hostname of the Server in a Cluster I was thinking if I can use the VIP address i.e ipaddress-VIP for either of the Node. So after making changes I would like to do some failover testing manually and I am stuck here. How do I go about the testing scenarios.
For Eg: if DBHOST token value is VIP for Node 2, connections are coming in to Node2 via deployer how do I proceed with the testing
Should I bring down Node 2? If I reboot how can I see if it failed over or not to the surviving Node?
Any help/suggestions much appreciated.
Thanks!
What you describe is having a RAC cluster, possibly working possibly not, and no actual use of the value of the licensing you paid for.
My first advice to you is to read the docs and learn what RAC is, how it works, how to define and use services, and how a properly configured LISTENER.ORA and TNSNAMES.ORA should be constructed so you can compare that to what you have. With 11gR2 you should connect to the SCAN not the VIP.
Here's how I would test RAC:
1. Walk up to one of the servers while half the users are connected to each instance and do a SHUTDOWN ABORT. See what happens. Restart the killed node. Try it with the other node.
2. With everything running properly and load on both machines disconnect the switch that provides the cache fusion interconnect or pull one of the cables out of the server. When you reestablish the connection what happens?
3. Repeat #2 but this time with the connection to storage.
The above should get you started.

Oracle 11g clusterware VIP failover failed
I installed Oracle 11g Clusterware succesfully, without any errors as per link:
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnRHEL5UsingVMwareESXAndNFS.php
After that,I did vip failover test
I rebooted the node-2

I have only 1.5G on each node
Here the issue is,
1. Actual Result: # During failover why it is showing UNKNOWN state for ora.rac2.vip on member rac1
Expected Result: # During failover,it have to be ONLINE state for ora.rac2.vip on member rac1
2. I have to start ora.rac2.vip manually, when node-2 is up.I want VIP fail over have to happen automatically when node-2 is up to normal online state.
Help me out from this issueVMware is unsupported but that is likely not your issue.
1. Run cluster verify and report the results
2. Did you create a failover service? How?
3. Post your TNSNAMES.ORA -
Vip Failover and rolling patch
Hi,
For the purpose of implementing security features in the 2 Node RAC DB EE=10.2.0.5 [ID 1340831.1], I want to apply patch for bug:12880299 which is rolling available.
My question is: If I do all this procedure on node 1 (creating wallets,self-signed certificates,stop/start instances on the node), the node 2 DB should continue to accept incoming connection requests right?
In another way, I have tested FAILOVER tests while crashing node 1, and VIP was failed over to node 2, but I have no idea how vip will behave if DB,LISTENER,CRS,etc are literally stopped on node 1, will it still automatically move to Node 2?
Also, prior installation of PSE 12880299 before implementing COST in this verison of DB? Is this necessary whatever it is?
Thank you for your useful inputs.
RegardsWith Oracle 10g you do connection time failover with setting in clients tnsnames.ora file all nodes addresses: Check following link:
http://docs.oracle.com/cd/B19306_01/network.102/b14213/tnsnames.htm#i477297
If your clients tnsnames.ora file is ok, Then client tries to connect addresses one by one. And this way it does not matter even if some server of the cluster is down. But of course when you shutdown one database instance it's connections will be dropped. Althought you can have SELECT clause failovers with Transparent Application Failover (TAF).
So you can run rolling update without shutting down whole RAC database as long as your clients tnsnames.ora is configured correctly. But those dropped connections need to be handled in application level. -
Hi,
Anybody did 11i/10g RAC Failover test. How to do the test and what steps involved. What is expected when one node down?
my config
web, admin, form - appsnode1
concurrent / db (rac1) - dbnode1
concurrent /db (rac2) - dbnode2
Thanks for your help.
RegardsYou can check the below
1. VIP Failover - VIP should failover when node gets rebooted.
2. When one of the node is down you should still be able to logon to applications.
3. Since you have only one node and do not use PCP you CM processes will die.Make sure you start them.
4.Once you bring the node back , test your load balancing is happening fine across both the db nodes.
Let me know if this is helpful/correct and if you need more information.
Regards

Dear all,
I am using Oracle Rac 10gR2 running on top of Sun Cluster 3.2u3.
I have a test to check the failover ability of VIP in Oracle RAC, however the result was not as I expected.
The test scenario was:
- Turn on the 02 nodes and wait for all services including both Sun Cluster and Oracle RAC online.
- Using SQL Navigator to connect to the database using the VIP on node1. (VIP1)
- Shutdown the node1.
- All services and resources on node2 still online, however after a long time (about 10 mins), I did not see the VIP1 failover to the alive node.
- The "crs_stat -t" command did not show the VIP1 online on node2 (alice node).
- The SQL Navigator could not establish the connection to the databasse using the VIP1 any more.
The output of "crs_stat -t" command before shutting down the node1:
oracle@t5120-02 $ crs_stat -t
Name Type Target State Host
ora.orcl.db application ONLINE ONLINE t5120-02

The output of "crs_stat -t" command after shutting down the node1:

So my questions are:
- Was my test scenario correct to check the failover ability of VIP in Oracle RAC?
- Is there any additional configuration needed to perform on the system to achieve the VIP failover?
Please help me in this case as I am new to Oracle RAC.
Thanks.
HuyNQ.Dear Rajesh,
Sorry for late reply.
I have already tested 02 cases: shutting down a node and crashing a node. Below are the output of the log files in the 2 test cases.
Once again, when shutting down a node, the VIP did not failover although the CRS on that node was shutdown before all other services and resources of Sun Cluster shutdown.
Please help to check the log files and give me advise if you see anything abnormally.
Thanks.

N+1 5508 WLC failover test
Good day all,
I have a question about the N+1 5508 failover test:
Should I shutdown one of the primary WLC to test failover?
I just setup the N+1 bakcup WLC (5508). B
Based on: http://www.cisco.com/en/US/docs/wireless/technology/hi_avail/N1_High_Availability_Deployment_Guide.pdf
We have two production WLCs both 5508 and one 4405.
We just purchased another HA-SKU WLC 5508.
All our four WLCs had been setup into one mobility group in version 7.4.100.6.
Their neighbors are all up.
But our test AP could not register to the Backup N+1 WLC. ( We are using option 43 in our DHCP server for all the AP boot.)
Here are the log screen:

Dataguard switchover & failover testing
i want to build new physical & logical dbs just for testing & learning, as per menalink notes 736863.1 & 748595.1
wondering that configuration will let me test switchover & failover testing?Hi there,
Those notes help you to build a proper data guard configuration in both Physical and Logical Standby enviromnment.
I would also recommend to check:
- [The Oracle online documentation|http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/toc.htm]
- [Oracle Maximum Availability Architecture site on OTN|http://www.oracle.com/technology/deploy/availability/htdocs/maa.htm]
These documents can provide a big picture of Data Guard configurations from different approaches as well as I would also recommend to learn and practice more advanced techniques and features such as Flasback database, Fast-start-failover or Cascaded destinations.
Hope this helps,
Good luck and regards,

As part of an ISE implementation, I want to test ISE failover for Admin, MnT, and PSN personas. Does anyone have an ISE failover test plan or ISE failover test best practices documentation to share?
Thanks much,
David DaversoSteps for Administration persona failover testing
1. Stop ISE services on Primary Admin
Primary Admin# application stop ise
2. Log in to the Secondary Admin GUI and manually promote to Primary
3. Wait 10-15 minutes before process is complete
4. Verify ISE services are up on promoted Secondary Admin
Secondary Admin# sh application status ise
5. Promoted Primary Admin checks
Deployment pages shows all nodes are green and in synch
6. User testing to verify successful authentications and logging
Note:
After you promote your secondary Administration node to become the primary Administration
node, you must reconfigure your scheduled Cisco ISE backups in the newly promoted primary
Administration node
because scheduled backups are not replicated from the primary to secondary Administration
node.
7. After step 6 testing is complete restore original Primary Admin
8. Start ISE services on original Primary Admin
Primary Admin# application start ise
9. Verify ISE services are up on original Primary Admin
Primary Admin# sh application status ise
10. Promoted Primary Admin checks

Redundancy/failover testing
My company is a relatively small enterprise (about 800 people scattered across 45-50 branches) and we are planning on setting up a periodic failover/redundancy testing schedule for our routers. Basically, we want to test the secondary WAN links at our branch offices and test our redundancy in our data centers.
I'm sure there is plenty of documentation out there in regards to best practices, but what I find has more to do with a full DR test of a enterprise's systems, as opposed to a simple failover test of an office's WAN link.
Does anyone have good suggestions for how often you should run these tests? My original thinking is to do this every quarter, but this would involve some travel for us and our resources are slim. The branch offices can be done remotely without any issue, but our DR site (which is actually used for some production traffic) would probably require one of our staff to be on site during a redundancy test.
Thanks!Yep, that's what I did now.
But keep in mind this is not really explained, even if crossing all the documentations.
There is no document explaining what behaviour to expect in Jabber in case of redundancy of all the UC components.
For the CUCM, it's not clear, and nothing is mentionned in case of MRA.
IM&P is documented, but nothing for MRA.
Expressays states about redundancy, but the behaviour to expect is not. Same for XMPP federation, no idea.
UnityConnection as well, nothing is explained. -
JMS queue| failover test question
HI gurus,
We are planning a failover test to migrate from prod to contingency environment.
What happens to transactions that may be sitting in the JMS queue when the prod jvms are stopped? Is there a way to migrate them to the cont jvms?We are using jdbc stores and the supporting tables for both prod and cont will exist in the oracle DB, but with different names. Since the CONT jvms will be using different tables for the JMS queues, is there a way to migrate those queued transactions from prod to the CONT side?
Details of environment
1) OS for App Server
Linux x86-64.
Linux va2xpre03.gdsososos.com 2.6.18-128.1.6.el5 #1 SMP Tue Mar 24 12:05:57 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
2) App Server type and version
WLS 10.3.0
JDK version
jrockit_160_11
3)
Clustered and it is a Prod environment.
Details:
UI cluster has 5 servers. There are 4 jvms in each server. Altogether there are 20 jvms in UI cluster
Recon cluster has 3 servers. There are 4 jvms in each server. Altogether there are 12 jvms in Recon cluster
regards,
Thiago Leoncio GuimaraesA common practice for handling this type of fail-over is to ensure that the main environment's domain name, server names, store, transaction logs (default store), and JMS configuration all all the same in the contigency environment (basically, differences, if any, are confined to things like URLs and Data Source configuration of DB location). Recovery is accomplished in the fail-over environment by copying over each server's default file store, as well as its JDBC store backing tables, prior to booting the fail-over servers.
Transaction logs don't need to be copied over if you don't use XA (JTA) in your applications... -
Recreate standby after failover test
Hi -
I'm doing a failover test for the customer:
1. Disconnect all network between Primary and Standby
2. On the Standby - do a failover and open it to perform application tests.
3. After finish we need to re-create Standby again.
Is there a way to re-create Standby again without bringing it all from backup? it's a large 2TB database and it will take hours.
Is there a way like using flashback or other technology to do it?
We are talking 10.2.0.3 here...
Thanks

We are talking 10.2.0.3 here...Its called "open the Standby database in read write mode for any reporting or testing and then move it back to standby database using the flashback technology".

Sap not starting during manual failover testing
Dera friends,
We are performing manual failover testing between CI(sap central instance) and DB(oracle database)
the environment is ECC6.0 on AIX server
CI is running on one server and DB is running on another, during manual testing we have failed the DB, so now DB file systems has got mounted on CI server.

ABAP Database IRP must be started on remote server
===============================================
why am i getting this "ABAP Database IRP must be started on remote server" message.
What could be the cause for my database not comming up & why is it looking for remote server, when all the DB filesystems have got mounted on CI server (the server that has CI installed)
We are in a bad shape and the issue is quite crticial.
Your reply would be highly appreciated.
Regards
Ayush> how can i check wether the directories are missing or not...
mount?
> Also how can i check it wether they are assigned to failover group or not.
Ayush, no offense, but I suggest you contact your AIX guy and check with him together. It's very cumbersome to write down command by command, get the outpu t back and you have no clue what you are doing. Again, no offense.

VIP Failover at the web server level??
Oracle10gR2
RHEL 4 AS 64bit
Hi,
I wanted to know is the VIP failover at the web server level also? For example, we are running Apex and that uses Apache/HTTP webserver, if that were to go down on one node, would it failover to the other node? Or is it not at the webserver level?
Thank you.Yes, thank you for the documentation.
However, I had one question about an action script that is in the following documentation:
http://www.oracle.com/technology/products/database/clustering/pdf/Using_Oracle_Clusterware_to_protect_Oracle_Application_Server.pdf
In there in APPENDIX B is a script called webcache_action.scr. I modified this script to use in our environment to start and stop the http_server process. We have been having some problems with it...mainly when it fails over, it shuts down the http server, then brings it back up, then down again. This is happening in a production system so it's a big issue. My question is can you explain to me why that is happening and maybe also explain what the script is doing? Maybe I'm missing something. Do I even need to have the stop part in the script? All we need to do is when it fails over to startup the http server on the node, that's it! Any help would be appreciated.

Hi all,
I am creating a failover test script that is simple and is doing insert 1 row every 2 seconds.
Then we fail the node1 and check if it will continue to insert on node2.
My script is using sqlnet client connect. for example :
connect scott/tiger@TEST
So I still need to install oracle client on my laptop.
I want to create a script that will not need Oracle client or tns names.ora in my laptop. How do I do it?
I want it to behave like what the sqldeveloper do in which no tns names is needed and uses the parameter: hostame: port: SID
Thanks a lot,
zxy

But I dont want anything to be installed in my laptop. I only want the program to use or ride on the functionality of sqldeveloper which you just cut n paste.
You could write a Java program that uses JDBC to connect - that would be one way.Can you share a sample java program that behave like sqldev? and rides on it? becuase I do not want to install other tools.
ThanksHere's a simple Java program. Just compile it with javac, set your CLASSPATH to include ojdbc.jar, and run it with java:import java.sql.*;
class Conn {
public static void main (String[] args) throws Exception
Class.forName ("oracle.jdbc.OracleDriver");
Connection conn = DriverManager.getConnection
("jdbc:oracle:thin:@//localhost:1521/orcl", "scott", "tiger");
// @//machineName:port/SID, userid, password
try {
Statement stmt = conn.createStatement();
try {
ResultSet rset = stmt.executeQuery("select BANNER from SYS.V_$VERSION");
try {
while (rset.next())
System.out.println (rset.getString(1)); // Print col 1
finally {
try { rset.close(); } catch (Exception ignore) {}
finally {
try { stmt.close(); } catch (Exception ignore) {}
finally {
try { conn.close(); } catch (Exception ignore) {}
}OK? -
