Admin server is part of cluster?
I have setup a cluster using on 2 unix boxes. 1 unix box contains 1 WL server
that is both the admin server and a member of the cluster. It appears to be working
ok.
Will this cause me problems later?
Admin server should not be part of cluster.

Error starting Admin Server in a OSB Cluster installation
Greetings
I have an environment with two osb nodes in cluster, when I start the Admin server the server start succesfully and the osb servers also works fine, but I got the following messages starting the admin server:

I am worried because I see in the deployment screen that the applications File Transport Provider, SFTP Transport Provider, Ftp Transport Provider and Email Transport Provider are not running.
How can I solve this issue?
My installation is osb 11.1.1.6 and my operating system is solaris 11 (64 bits)
Thanks!Hi Charan,
if your ManagedServers are not in Configured for MSI Mode (Managed Server Indepence Mode) then you wont be able to start your Servers until the AdminServer is Already Running. I can see that the Exception u pasted that...your AdminServer is not reachable....It may be due to AdminServer Vs ManagedServer BOX Network Issue or Your AdminServer might be down when u tried to start the ManagedServer.
Thanks

Admin server can't see session info when app is running in cluster
All,
We have 3 servers running WL6.0 sp1, 1 is running the admin server and the
other 2 are running as part of a cluster.
We have a web application that has been deployed to the cluster and is set
for PersistantStoreType equal to replicated.
Enable session monitoring is set.
If one of the servers in the cluster is running and we connect to the admin
server we can see both the servelet and session statistics for the
application.
If both servers are up and running, we can see the servelet statistics for
both servers but the session information is always 0.
Is this a bug or is there something else we need to have set.
Thanks
Eric
Is this what you are looking for?
monitor = new URLMonitor(new URLRequest("http://localhost/gateway.php"));
monitor.addEventListener(StatusEvent.STATUS,onStatus);
monitor.pollInterval = 5000;
monitor.start();
I use it to poll a server every five seconds and when there is a change is status to connected it triggers the onStatus function I have defined elsewhere. Learned it from Lynda.com's videos... -

That's not true. Starting a cluster has nothing to do with admin server.
Infact we always recommend to exclude admin server from cluster view.

Cookie bug using Administrative Server as part of the Cluster
All using Weblogic 6.0:
Administrative Server running on Windows 2000 Professional
Managed Server running on Windows 2000 Server
Both machines running in the same cluster.
Requests being proxied by the Windows 2000 Professional machine running IIS
Ok, now that you know our test environment, here's a little about our bug.
If we begin an http session with requests being fulfilled by the
administrative server (through the proxy), and shut down and bring the
managed server back up, everything is fine. (No big surprise.)
However, if requests are being fulfilled by the managed server and the
administrator goes down and then comes back up, we get a
"ReplicationManager: object 722399223287670702 not found" error, where the
number seems to refer to value stored in the cookie after the last OR
symbol as shown below.
When the session is created, the cookie contains the following value:
session id =
OnIXh5A6DxUWgBrA2qCLIDN0Co1dewmjdV1ze1isn9Wur2CHl2k2|60563422118895
84610/-1062731365/7001/7002|4648941459387506517/-1062731381/7001/7002|722399
223287670702
When the administrative server goes down, the cookie contains the following
value:
session id =
OnIXh5A6DxUWgBrA2qCLIDN0Co1dewmjdV1ze1isn9Wur2CHl2k2|60563422118895
84610/-1062731365/7001/7002|NONE|722399223287670702
When the administrative server comes back up, the cookie contains the
following value:
session id =
OnIXh5A6DxUWgBrA2qCLIDN0Co1dewmjdV1ze1isn9Wur2CHl2k2|60563422118895
84610/-1062731365/7001/7002|4563245475623454445/-1062731381/7001/7002|722399
223287670702
Its pretty obvious how the cookie id breaks down, information before the
first OR is client info specific to each client, between the first and
second OR is information regarding the first server from the cluster to
fulfill the requests. The info between the second and third is the
identification of the backup server containing the replicated version of the
session. And the last bit of information seems to be an ID referring to the
session object as stored in memory. As you can see, the value that the error
is referring to never changes. SO WHY DOES THE OBJECT GET LOST?
This is a big problem for us, as our resources are limited (as I assume
everyone else's is). Is this just a bug? If so, is there a service pack
already available? If its not a bug, it should be as resolving the bug
allows the administrative server to be part of the cluster saving everyone
the money for an extra machine and (here's the killer) the money for an
extra weblogic license to run on a administrative server separate from the
cluster (in which case it works fine, just costs a whole lot more).
Well, I hope this is clear enough. If not please ask whatever you need to
know. We are looking for any information anyone can provide.
Thank you,

To answer your question, fail over works fine, i.e. if a session is
maintained on the managed server, we can shut it down and the session is
transferred to the administrative sever.
The only problem we are having is when the session is on the MANAGED server,
and the ADMIN server goes down and back up WITHOUT any session transfer.
As for shutting down an admin server, you can bring it back up while managed
servers are running by using the -Dweblogic.management.discover=TRUE
setting.
I hope this clarifies everything.
Thanks again,
Chad

CLLUSTER1 and CLUSTER2 are the servers to be in the cluster. CLUSTER3 is the cluster
administrator. We start CLUSTER3 as a self-managed server and then try and start

Don't start the admin server as managed. Removing

from the command line should help.

Starting weblogic cluster and admin server on Win 2000 platform
Hi! Here's my problem scenario:
I'm running my WLS 8.1 application as WLS cluster on Win 2000 platform. I have
3 replicated WLS servers in my cluster and of course one WLS server as admin server
(4 WLS servers all together). I'm starting my WLS application using Win services
which behind a scene call win 2000 comand interpreter batch-file to start the
servers. Currently I have 4 different win 2000 services each calling different
batch-files to start a WLS server (4 all together). Here's my question:
Is there any way to start my cluster (3 managed WLS servers) and WLS admin server
from single win 2000 command file (using single win 2000 service). Using win 2000
AT-command interpreter command I can start executables and command(s) and command-files
at background at specific date and time, but I want to start my WLS application
on every win 2000 platform boot, is there any way to achieve this ???
Best Regards!
Jamihi,
Thanks for stepping up!
But I wasn't using any clustering or loadbalancing.
Just a simple Admin server, Managed server set up.
256 Meg, Pentium box running Win 2000 premium edition.
I tried tweeking around the heap size too.... coz' the operations were slogging
like anything...

hi,
I am looking at a strange behaviour with WLS6.0SP1 installed on WINDOWS2000 Premium.
I brought up the Admin server and a Managed server. After a while theAdmin Server
is compeletely
losing the control of the managed server (for no reason).
when I tried monitoring the managed server from the console, I couldnot
access
the manager server
and the status down (red ball). I tried restarting the Admin Server
in the discover mode - NO LUCK.
But when I restart the Managed server and go to the Web Based Admin
Console and refresh, it worked. But I dont think we should be doingthat
in a

Did anybody come across such a problem before ???
Is this a problem with Win 2000 ???

Hi,
I'm setting up WebLogic cluster (horizontal with 2 managed servers spanning across 2 machines).I would want to have admin server on each machine and only one admin server will be active whiel the second admin server will remain shutdown
.Can anyone please explain how I can set this up with 2 adminsitration servers and how do I make it active-passive mode for admin server and how i can bring it up in case of 1st admin server going down
Any documents would be really helpful
thanksThere can be only 1 Admin per WebLogic Domain....not more than one.
Please refer to Know more about *"What is Administration Server?"* http://weblogic-wonders.com/weblogic/2010/06/18/weblogic-initials/
If you are talking about *" Whole Server Migration "* then please refer to: http://download.oracle.com/docs/cd/E11035_01/wls100/cluster/migration.html
Note: Server migration is only supported when you use the SSH version of Node Manager. Server migration is not supported on Windows.
When a migratable server becomes unavailable for any reason, for example, if it hangs, loses network connectivity, or its host machine fails—migration is automatic. Upon failure, a migratable server is automatically restarted on the same machine if possible. If the migratable server cannot be restarted on the machine where it failed, it is migrated to another machine. In addition, an administrator can manually initiate migration of a server instance.

Weblogic admin server in the cluster !!!!
Hi,
I am working on weblogic setup already done by my ex-colleague. I observed that, the admin server is also participating in the cluster and hence it is also one of the targets for EJB components, datasource and connection pool. Is there any performance issue in this setup ?
thanks for your time.Thank you for your reply.
I forgot to tell you that the admin server is not an individual machine. It is setup in one of the weblogic App. servers. Therefore, I feel it is better we do not add this admin server in the cluster.
You can give me your advice. ---- topic 1
By the way, I had posted one question about targeting a datasource to the individual servers rather than to a cluster. In the existing setup, the datasource is targeted to individual servers rather
than to the cluster. The setup is running without any error.
But as per the BEA manual, we have to target the datasource to the cluster if we use cluster. So, in my current setup, is there any performance issue or may I face any problem in future by not targeting the datasource to the cluster? I appreciate if you can
try this question. ---- topic 2
Thanks in advance. -
Admin Server Funcationality in a WebLogic Cluster
Is this a correct statement of how the Admin Server is handled in WebLogic Cluster:
"If you have a two node WebLogic 10.3 Cluster then you will have the Admin Server for the domain running on node1. The managed server within the domain will run on both node1 and node2. The managed server services your application(s).
If node1 fails then the managed server running on node2 will continue to operate, thus meeting your high availability requirement.
If you need to administer your WebLogic installation you will first have to restore node1 to an operational state so that you can access the Admin Server."
Thank youAnswers :-
Q>"If you have a two node WebLogic 10.3 Cluster then you will have the Admin Server for the domain running on node1. The managed server within the domain will run on both node1 and node2. The managed server services your application(s).
A>Admin server can be running on any node(Physical machine). One Managed server(say MS1) can run only on one node. Two nodes can host two different managed servers. Yes, managed servers services your applications.
Q>If node1 fails then the managed server running on node2 will continue to operate, thus meeting your high availability requirement.
A> Yes, that is the reason of using clustering : Load balancing and failover.
Q>If you need to administer your WebLogic installation you will first have to restore node1 to an operational state so that you can access the Admin Server."
Yes, if admin server was running on node1, then it needs to be up and running to administer the domain. -

- I choose expand cluster on IDM configuration wizard windows (oim_11.1.1.7.0)
- I entered the admin server address, port, username, password, all of them is correct because I tested them on all nodes and from my remote laptop
- when I hit the Next button, that error occured:
INST-07242 Unable to connect to Oracle Weblogic Middleware Administration Server
Make sure Oracle Administration Server is up and hostname, port, user name and administration password are correct.
I don't know what the reason of that error. On the Metalink I watch the doc ID:1324425.1 but the solutions mentioned to earlier verions than mine. So that I cannot apply that solutions.
Have you got any idea ?
Thank in advance.

6.0 cluster startup without the admin server...
Is it possible to start a WL6.0 cluster without the admin server being up
and running? If not, are there any workarounds that eliminate the admin
server as a single point of failure?
I have same questions.
1.The admin server's primary task is up the cluster?And if admin server is down
that can't affect the cluster running.
2.Is it right when the cluster is working,the useful ip is admin server's ip?For
example,admin 10.10.10.1,cluster1 10.10.10.2,cluster2 10.10.10.3,the only useful
ip is 10.10.10.1 in the cluster.
3.Is it correct that because the only useful ip is 10.10.10.1,therefor my client
access the cluster from 10.10.10.1?
When my admin server is down,then my system will be down.
4.which is the dispatch in the cluster system ?
my step of configuration of th cluster:
1.add two managed servers to admin server and edit startweblogic.cmd;
2.config cluster.(admin server address 10.10.10.1:8168,cluster address 10.10.10.2:7001,10.10.10.3:7001),multicast(237.0.0.1)
please help explain these questions!thanks a lot!

Cluster member caches a copy of DefaultWebApp from admin server
Hi,
It seems that when a cluster member starts up, it fetches a copy of
DefaultWebApp web application from admin server, and keeps it under a
directory of $BEA_HOME/wlserver6.1/config/mydomain/applications/.wlnotdelete_$SERVER_NAME,
and it doesn't look into its local copy of DefaultWebApp even being
modified.
How does this happen? How can it be disabled?
Thanks in advance,
William
Hi,
this does probably occur due a change in WLS 6.1 which was done in order to assure the server
to function properly even when the customer deletes the defaultWebApp. If this is the case
this
cannot switched off.
Do you observe other symptoms, which lets you think you have a problem with your server ?

Newbie cluster question: where does the admin server live?
Hello, I'm looking at clustering for our application where I work, and so I'm reading through the cluster-related documentation for 11g. I have a sort of an architecture question: where should the admin server be started? Hypothetically speaking, if you have two nodes for your cluster, would the AdminServer run on a 3rd box which sort of stood in front of the two nodes?
Thanks much -The ideal situation would be for your admin server to be separate from the machines hosting your managed server. This allows you to control access to the admin server, eliminate the performance impact if you have the admin + managed on the same host, and limits impact if youir #1 host fails, etc.
But companies may be unwilling to invest in a distinct (3rd) host just for the admin server, especially if you have multiple environments ( prod, testing, dev, etc. ).
So usually the admin winds up sharing the host with a managed server. -
Strange WLS6.sp2 Oracle DB Reconnect issue in a Cluster but ONLY on the Admin server
Any Ideas? ->
I am having a issue when our oracle db server goes down and when we try
to reconnect the Pool via weblogic I am getting this error. This only
happens on the Admin server for the cluster, none of the managed servers get
this and they all seem to be ok. Any ideas?

va:398)Hi,
As i understand is OS is clustered not the db. Better is to manually shutdown the db clean and then start it.
TO start login through sqlplus sys as sysdba
1. startup
2. Once its done, start the listener
3. Start the application
