WLS10 Admin Server disconnecting from managed servers

Anyone come across this issue?
We have a web service using the Apache Axis2 framework running on a WLS10 server on AIX O/S. The managed server that host this web service regularly disconnect from the Admin Server. The server status remains in a 'Running' condition and the web service remains in an 'Active' state but the Health state from the console which should read 'OK' appears blank and the web service is non-responsive. The only way to get out of this issue is to bounce the server which we are doing anywhere from 1 to 5 times a day. Any ideas on why this is happening?

some times it may happen due to WLS version difference between admin server and managed server. Please make sure managed server is not running with latest version than admin server. Or it can be JDK issues with memory settings and garbage collection. Or it may be related admin traffic iin domain. these are my guesses only.

1 NodeManager, 1 Admin Server and 2 Managed Servers

Hi All, I'm new in Weblogic and this is my 1st time to post a question on this forum. Would like ask for help from you all above my setup, I'm not sure whether it will work or not. Please find out the scenario below:
Setup:
1 Machine (RedHat Enterprise Linux 5.5)
1 NodeManager
1 AdminServer (Name: APP)
2 Managed Servers (Name: APPLIVE, APPUAT)
Currently I would like to using one NodeManager to control both Managed Servers under 1 machine. When I configure my APP Admin Server and two Managed Servers, i would like to nmEnroll both Managed Servers under one NodeManager but it will overwrite my enroll entries if i enroll 2nd Managed Server.
Is it possible to configure NodeManager to accept both Managed Servers entries? Thanks. :)

Hi Hong,
Following are the few things which you help you understand about NodeManager and nmEnroll
- First of all a Node Manager process is not associated with a specific WebLogic domain but with a machine
- When you run a nmEnroll then you just give "domainDir" and "nmHome" which would then gets the file called "*nm_password.properties*" which contains the encrypted username and password that is used for server authentication and "*SerializedSystemIni.dat*" file.
Example:
nmEnroll([domainDir], [nmHome])
- With above files it also updates the nodemanager.domains file with the domain information which was mentioned in the above command.
Thus when you run the nmEnroll command it would get all the details which it needs to start any managed servers in the same Machine, hence you do not need to run the same commend for each managed servers in the same Machine.
For more information have a look at the below links:

Run Admin Server with multiple Managed Servers each using different userid?

We currently run separate WebLogic domain instances for each business application in a Unix environment. Each one is created using a unix userid unique to that application and which owns all the files and is used to run the process when that particular WebLogic instance is started up. We have run this way for a while.
I am considering altering our approach to the one that is recommended, i.e. in our Production environment we would run a single Admin instance with numerous managed servers. One issue I'm stuck on is the fact that in our current environment, each application has a different unix userid that owns the files making up the WebLogic domain instance and that WebLogic instance is run under that userid.
I've investigated and experimented using WebLogic 10.3 preview and WebLogic 10.0, but I haven't been able to determine what I have to do to make each managed server's files and processes belong to a different unix userid, if that is even possible.
Is there a way, using the recommended approach, where there is a single Admin instance that has multiple managed servers whose files and processes are owned by different unique, unix userids?
If not, how would you separate access to each of the Managed Servers so that the programmers who maintain them don't have access to Managed Servers that they are not responsible for?
Thanks for any help or suggestions.....

Hi:
I played with this stuff and I found that this will work, without the Location elements:
<IfModule mod_weblogic.c>
MatchExpression /app1 WebLogicHost=server1|WebLogicPort=7003
MatchExpression /app2 WebLogicHost=server2|WebLogicPort=7003
</IfModule>
Also this will work too, with no entries inside the IfModule element:
<Location /app1 >
SetHandler weblogic-handler
WebLogicHost server1
WebLogicPort 7003
</Location>
<Location /app2 >
SetHandler weblogic-handler
WebLogicHost server2
WebLogicPort 7003
</Location>

OBIEE hosting on WebLogic - Admin Server vs. Managed Server

What is the difference between the two possible configurations of WebLogic: Admin Server and Managed Server?
I need to identify which one is adequate to host OBIEE Presentation Services.

http://download.oracle.com/docs/cd/E14571_01/web.1111/e13716/understand_domains.htm#DOMCF115
What Is a Domain?
+An Oracle WebLogic Server administration domain is a logically related group of Oracle WebLogic Server resources. Domains include a special Oracle WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the domain. Usually, you configure a domain to include additional Oracle WebLogic Server instances called Managed Servers. You deploy Web applications, EJBs, Web Services, and other resources onto the Managed Servers and use the Administration Server for configuration and management purposes only.+
I added the emphasis on "usually". You will always have exactly one administration server for a domain. That administration server can host other applications, it's simply a question of whether or not it's a good idea to do it. If you need to scale-up your application at a later time so that more than one server would be required - deploying your application to managed servers makes this very easy as you can just add managed servers. Typically other Oracle products in Fusion Middleware have domain templates and other installer / configuration options that default to deploying their infrastructure to managed servers. Sometimes in development / resource-constrained environments people override those defaults and try and run everything on a single Admin Server. It's usually possible, but may not be the most flexible going forward.

Setting up an admin server (win) + a managed server (linux)

I am trying to set up the following domain on weblogic 8.1 SP2:
1. An administration server (+workshop) on my local Windows box
2. A managed server running on a red hat enterprise box, that connects to the
administration server on my windows box.
I've not been able to find any documentation on this, and the installation process
is far from intuitive.
Can someone help me with a step-by-step guide? I'm not trying to do anything fancy
here ;-) Thanks!

Resolution found:
Went through the config.xml file. Found that in the server tag the listen address
for the server and managed server is not there. Entered the Corresponding listen
address for both Admin and Managed server

Involving multiple machines obviously adds some complexity but for a

to
create domains (with the same name) on both machines. On the admin server
machine,
use the Custom path in Config Wiz to add the managed server, and onthe

use startManagedWeblogic
on the managed server machine, specifying the managed server name and

In a production environment, you'll likely use node manager to start
managed servers
and a domain does not need to be created on the managed server machine
in that
case.
edocs has lots of good overview information and details on using Config

Problem starting Admin Server using Node Manager

I have configured the Node Manager to run as a windows service. I want it to start the Admin Server when it is started. This is not working. The Node Manager starts without problem but does not appear to even attempt to start the Admin Server. No error message is written to the nodemanager.log. I have configured the following properties as described in the documentation:
StartScriptEnabled=true
StartScriptName=startWebLogic.cmd
Starting the Admin Server using wlst works. As does starting and stopping a Managed server using the Admin console. This leads me to conclude that the Node Manager configuration is ok.
WLS version is 9.2.
All suggestions as to what could be the issue here would be greatly appreciated.
Cheers!

Ok, I just wasted a whole day before I found the tricks.
First, you don't need to do that StartScriptEnabled stuff, unless you have important things to add there.
Ok, and now what I found:
- You must make sure you have installed the NodeManager as a service
- Next, make sure the admin server is assigned to the right machine. Since you can do the WLST trick, that should be fine. If not, tough luck, because the docs say you cannot re-assign an admin server.
- In nodemanager.properties (...\weblogic92\common\nodemanager) make sure CrashRecoveryEnabled is set to true
- In nodemanager.domains (same dir) make sure your domain is mentioned with its path
- For each of the servers to be auto-started, make sure that a startup.properties (in <your-domain-dir> \servers\<server-name> \data\nodemanager) contains Arguments=-Xnohup (for JRockit, for Sun JDK its -Xrs)
Make sure they are started through the nodemanager, et voila, they'll be restarted after a reboot.
Why this works? At reboot, the OS ask all processes to die, nicely. Those that don't, get killed forcibly. Without the -Xnohup/rs, the WebLogic servers respond to the nice request, and the nodemanager immediately tries to restart them. Unfortunately, the OS refuses to do that, and the server process is marked as failed, and won't be restarted after reboot. With the option given, the servers ignore mr nice guy, and get killed after the nodemanager has disappeared.
What can go wrong? A lot. I was playing with the nodemanager username and password, and that took some time to clean up. I probably have to redo the entire setup just to make sure I have a repeatable experience now...
Cheers,
Bert

Admin Server conole for managed Server

I have one question regarding weblogic server 10.3 If the Admin Server is Not avilable can we make the consoleApp Deployed on the AdminServer make it avialable on the Managed Servers?
If that is possible then please let me know the steps how to do?
any suggestions would be appreciated

Hi Eden,
 Without having an AdminServer if we are able to make changes then Actually there is No Need of an admin Server at all
"consoleapp" is the application which is called as Admin Console application which gets automatically (Internally) deployed on the Admin Server Only... So if the AdminServer is down then u don't have any option to access the AdminConsole.
If your ManagedServers are running on MSI Mode (ManagedServer Independence mode ...Means Without AdminServer Running) It means those Managed Servers are using the Old Configuration files which the Admin Server has created when it was last booted.
Still if you want to make some configuration changes then you can try editing the *"config.xml"* and *"msi-config.xml"* (msi-config.xml file u need to edit only if you are starting your ManagedServers using NodeManager) file manually in each Managed Server Box. But that is not a recommended way....Afterwards u need to restart your ManagedServers.
NOTE If you will explicitly try to deploy the "consoleapp" to any of the ManagedServer then you will get the following Error: (where localhost:7001 is the AdminServer URL)

<Aug 27, 2010 9:34:44 PM IST> <Error> <Deployer> <BEA-149205> <Failed to initialize the application 'consoleapp' due to error weblogic.management.DeploymentException: Exception occured while downloading files.

E4200 built in Twonky media server disconnecting from PS3

I am having problems with Twonky disconnecting from my PS3 while watching movies from the attached USB drive...anyone else having this issue?
Any ideas on how to manually restart the media server other than turning off the drive or resetting the router? Or perhaps a solution to this in settings...

Same problem here with an XBOX 360. Seems to be a common theme in several threads. The only solutions I've seen posed by admins is to change the MTU to 1365 which doesn't make sense since these problems are reported for hardwired devices and ethernet already does 1500, or to upgrade the firmware and/or reboot... none of which work. I also get the same issue when streaming to a laptop from the router, but have zero issues when the same drive is plugged directly into the laptop. I've also had issues where the Storage tab only reports as connected to the drive at USB 1.1 until a reboot of the router. It will also say "No disks available" even though I can connect to the drive through UPnP. My drive is a Seagate 2TB on the "supported" list of external drives. I would just like someone to acknowledge this is a real problem with a solution forthcoming or I'm going to have to assume it's a hardware fail that no future fix/firmware update will solve or this thing is going to have to be returned.

[OVM 3.0.3] Rebuild server pool from existing servers with running VMs.

Hello everyone,
We would like to reinitialize the OVM Manager database since it's in a pretty "bad state": since it's been used for heavy test purposes there are object that cannot be deleted.
However, one of the OVM servers in a server pool is running production VMs.
Is it possibile to clean the OVM Manager DB and rediscover the existing server without loosing its machines?
Would someone suggest other options?
Think of it as a disaster recovery test...
All storage pools are SAN LUNs.
Best regards,
Alessandro

Uninstall the Manager.
Install a new Manager (using SE or EE as your database, as you're going into production) and pass the UUID to the runInstaller script using the -u parameter.
Discover your servers in the new Manager -- all the server pool information will be recreated.
If you have any iSCSI or NFS storage servers, add those back and then Refresh the Repositories.
Refresh/Rediscover the servers -- all the VMs will reappear, under the servers upon which they're running.
Note that the only thing you currently lose is the friendly name of your ISO images and VirtualDisk images.

Cannot connect to direct access clients from management servers

I have direct access setup on a Server 2012 machine and I have successfully added clients to it. Clients can reach internal resources and everything seems to be working great inbound. However, I am having some trouble with outbound management.
From the Direct Access server I can ping, RDP, browse files, etc... From the management server I have defined in the DA setup I can only ping the machines and nothing else.
I had worked with some MS tech support to get to this point, and they had me configure my DA server and the few management server with status IPv6 addresses. I'm not sure if this is necessary or if outbound managment should work using ISATAP?
My DA server is Server 2012, and the clients are Windows 8 and Windows 8.1.

You should be able to make outbound management work using either ISATAP or native IPv6. If you have configured native IPv6 and it's not working, there may be some kind of routing issue with the way that IPv6 is setup in your environment, or even a piece
of networking equipment that is not IPv6 capable.
If you're interested in trying the ISATAP route to see if you can get it working that way, Chapter 3 in this is dedicated to the setting up of ISATAP: http://www.packtpub.com/microsoft-directaccess-best-practices-and-troubleshooting/book

Portal page serving portlets from different servers

Can i make a portal page containing portlets which are served by different

Thanks in advance,

Amit,
Using WLPortal 4.0 the best way to access remote information is to use the
Web Service Portlet Wizard (available from the BEA Developer Center -
http://developer.bea.com/index.jsp). You would need to set up web services
on your different servers and then access the information using a portlet
created using the wizard. We will be delivering a more comprehensive remote
Portlet solution in a future release.

Hi,
 After administration port changed back to 0, it has no error and admin
 server
 can discover the managed server.
 However, the admin server cannot control the active/inactive of the
 deployment
 of the war/ear file in the managed servers after admin has discovered those
 managed server. What I have done is...
 1. click in deployment tab
 2. select a war/ear file from available box to chosen box
 3. click apply
 4. try to view in my browser
 5. 404 page not found
 6. restart managed server
 7. try to view in my brower
 8. got the page displayed in my browser
 ** I have tried active the ear/war files and inactive those files. the
 result is the same **
 Anything configuration I have missed?

What is the Ideal Production Setup For One Admin and 4 Managed Servers

Dear Experts
I will be starting with production setup including one Admin server and 4 managed servers in one single domain.
I am thinking of creating a single node environment(no clusters) as the machine has following configuration
OS : Windows Server 2008 R2 Datacenter
RAM : 48 GB
System Type : 64 bit
Processor : Intel(Xenon) 4 processors [email protected]
Can you please let me know if this configuration would suffice for the 4 managed servers if i assign Xmx and Xms as 4096 and Heap Space as 1024 to all the Managed Servers.
It is very urgent and i need to convey to the Infrastructure team if harware procurement is required.
We are looking at somewhere around 300 concurrent users(maximum load) and 100(minimum load) at a given point of time.
Please reply ASAP.
Thanks in advance

Heap size must be calculated according to the applications that are been deployed on each JVM.
With no deployments, you dont need more than 256k for managed servers heap size and 512k for adminserver. As biggest its your heap size, longer will take your garbage collection. And if you can prevent it, better do it.

Silent Install w/Admin and Managed Servers

I noticed on versions 11 and 12 of Weblogic, it seems the parameters available for a silent install have been greatly simplified to where it just does a base install. How would I go about getting it to do a silent install with an Admin server and 2 Managed servers? Do I need to do an install and update-install or is there a way I can do all this in 1 shot?
Thanks In Advance

An example is given here: Middleware Snippets: Automate WebLogic 12.1.2 Deployment.
