FrontEnd hosts in weblogic cluster

Hello,
I have set the frontEnd hosts in weblogic cluster(10.3.5) to the loadbalancer URL(https://xyz.com) . Webservice developed in 11g is deployed to the cluster. The dynamic wsdl generated contains the the Address of the frontEnd in <address> Tag of the WSDL file.
But when i try to test the service by clicking on 'test client' on the deployment page. It gives me following error
failed due to This service requires https,but the attempt to access Test Client at https address https://<ip address where weblogic managed server is running>:443/wls_utc/begin.do did not suceed due to java.net.ConnectException: Tried all:1 addresses, but could not connect over HTTPS to server:<ip address where weblogic managed server is running> port:443. In order to test a service that requires https the Test Client must be running on a server configured for https.
Can we configure the front end hosts point to https and still test the test client using the deployment page.?
Thanks,
Ram

Hi Kal,
I did try to enable SSL listen port. Though i am able to access WSDL but the Test Client is still giving the same exception.

Ram

Problem configuring front end host for weblogic cluster

hi,
I am using weblogic 8 sp4,I have a cluster of WLI servers for which i am trying to configure a front end host.I am using apache Http server 2.0.55 for the same.
I copied the mod_wl_20.so file to the modules directory and added the following to httpd.conf file
LoadModule weblogic_module modules/mod_wl_20.so
<IfModule mod_weblogic.c>
WebLogic http://myIP:9191,http://myIP:9192,http://myIP:9193
ErrorPage http://myerrorpage1.mydomain.com/
MatchExpression *.jsp
MatchExpression *.xyz
</IfModule>
<Location /weblogic>
SetHandler weblogic-handler
PathTrim /weblogic
</Location>
however,the error page gets displayed and not the default weblogic page.
When I change the Error page url to that of my cluster url(i.e)http://myIP:9191, the weblogic default page gets displayed .. I mean to say that the same url doesnot work with the WeblogicCluster parameter but works with
the ErrorPage parameter.
Somebody who has configured the front end host using apache http server please clarify, it would be of great help.
Thanks in advance

The error.log displays the following (sorry i forgot to add it above :-()

BPM Worklist Problem After Setting Frontend Host and Port

Hi all,
I was following the EDG for SOA 11.1.1.5 and was encountering a problem with the BPM Worklist after setting the Frontend Host and Port. We have a topology that includes a load balancer that terminates SSL, two OHS instances, and two SOA instances on separate VMs. When BPM Worklist was loading, it was calling webservices internally through the load balancer, but WebLogic was expecting them as http://. It was not able to resolve the HTTPS port that was being sent from the load balancer through the 80 to 443 redirect.
What the current EDG does not tell you, is that you have to also turn on "Enable Weblogic Plug-In" for WebLogic to use the OHS plug-in. I did it at the domain level, as all traffic will go through the load balancer. This essentially tells WebLogic that all URLs are https://
Here is an exerpt from the SOA.out log file:
<Sep 8, 2011 9:32:06 PM PDT> <Error> <oracle.soa.services.workflow.worklist> <BEA-000000> <<.> Service error.
Internal Error; Service error occurs in IdentityService in method lookupUser.
Refer to the log file that is configured for oracle.soa.services.identity for more details on this error and contact Oracle Support Services
ORABPEL-10585
Service error.
Internal Error; Service error occurs in IdentityService in method lookupUser.
Refer to the log file that is configured for oracle.soa.services.identity for more details on this error and contact Oracle Support Services
Caused By: javax.xml.soap.SOAPException: oracle.j2ee.ws.saaj.ContentTypeException: Not a valid SOAP Content-Type: text/html; charset=UTF-8
What it is also missing, is that you should also set the SOA Infrastructure ServerURL mbean for the load balancer, to match the frontend host and port. Do this through Fusion Middleware Contol. Otherwise, you could encounter URL mismatches.
I hope this helps someone else.
I've asked Oracle to add this to the EDG for SOA. It's in the IDM guide, but not in any other EDGs.

Thanks Josh. It helped me infact in 11.1.1.4 Enable Weblogic Plug-In is not required. But 11.1.1.5 I thing it is mandatory. Oracle should have a clear documentaion.

Apache Proxy Plugin with SSL in Weblogic Cluster

Hi,
I have configured a weblogic cluster and configured SSL. Then I configured the apache plugin to work with the cluster machines with non ssl and worked succesfull but when I configured the ssl communication between apache and weblogic I´m having problems.
The actual configuration is:
<Location /spmlws>
SetHandler weblogic-handler
WLLogFile /var/log/httpd/tmpweblogic1.log
DebugConfigInfo ON
Debug ALL
KeepAliveEnabled ON
KeepAliveSecs 15
WebLogicPort 7002
SecureProxy ON
TrustedCAFile /opt/freeware/etc/httpd/conf/trustedCA35cert.pem
TrustedCAFile /opt/freeware/etc/httpd/conf/trustedCA36cert.pem
WLProxySSL ON
RequireSSLHostMatch false
WebLogicCluster machine35:7002,machine36:7002
EnforceBasicConstraints false
</Location>
The problem is that the plugin always takes the last TrustedCAFile. In this way if machine36 is down the plugin tries to send all the request to machine35 but it takes the TrustedCAFile for the machine36 (/opt/freeware/etc/httpd/conf/trustedCA36cert.pem) hence the apache complains
[Wed Jun 30 11:13:56 2010] [error] [client 10.19.232.249] ap_proxy: trying GET /spmlws/OIMProvisioning at backend host '10.19.232.97/7002; got exception 'WRITE_ERROR_TO_SERVER [os error=0, line 796 of ../nsapi/URL.cpp]: '
What can I do to have multiple TrustedCAFile or to have working the communication between apache and weblogic cluster using SSL?
thanks in advance

Acording to the documentation this is not possible.
One way to achieve the load balancing of n-weblogic servers in cluster using ssl is to configure de HttpClusterServlet.

Timesten database driver is not supported in Weblogic Cluster mode domain??

Does anybody encounter this situation??
I have 2 managed server in a Weblogic cluster domain and there is DataSource for them.
In each managed server, I setup Timesten client correctly to connect to Timesten Oracle DB cache server.

Hi,
I have use WebLogic Server Console, tree: Services -> JDBC -> Connection Pools. Then I have choose 'Configure a new JDBC Connection Pool...':
1.) as 'Database Type:' I have select MySQL (version using com.mysql.jdbc.Driver) -> click 'Continue' button;
2.) 'Database Name:' = OSS; 'Host Name' = localhost; 'Port' = 3306; 'Database User Name:' = root; -> click 'Continue' button;
3.) 'Driver Classname:' = com.mysql.jdbc.Driver; 'URL:' = jdbc:mysql://localhost:3306/OSS; 'Database User Name:' = root; 'Properties:' = user=root -> click to 'Test Driver Configuration' button.
After click on test driver button I get message: JDBC driver is not on the CLASSPATH.
But when I check System variables (in Control Panel -> System) I have set up following:
CLASSPATH=.;C:\DB2\java\db2java.zip;C:\DB2\java\db2jcc.jar;C:\DB2\java\sqlj.zip;C:\DB2\java\db2jcc_license_cu.jar;C:\DB2\bin;C:\DB2\java\common.jar;C:\DBS\JDBC\db2\db2.jar;C:\DB2\BIN;c:\mysql.jar
The last value is 'c:\mysql.jar' and that's the mysql jdbc driver located on c:\.
I don't understand why weblogic cannot find it.
Any idea?
Thanks in advance for help,
with best regards,

Issue listeneing queue from Weblogic Cluster server with multiple managed server

Haveing issue listeneing queue from Weblogic Cluster server with multiple managed server.
Weblogic Cluster structure is like
Weblogic Cluster01
--ManagedServer01(http://server01.myhost.com:7001)
--ManagedServer02(http://server02.myhost.com:7001)
JMS Servers
JMSserver01 targeting: ManagedServer01
JMSserver02 targeting: ManagedServer02
JMSmodule
ConnectionFactory01 targeting:JMSserver01,JMSserver02
UDQueue01 targeting:JMSserver01,JMSserver02
Uniform Distributed Queue in Monitoring tab showing like this
mysystemmodule!JMSserver01@UDQueue01
mysystemmodule!JMSserver02@UDQueue01
So when I am sending message to any Host(by specifying the provider URL) its distributing equally on both server like
mysystemmodule!JMSserver01@UDQueue01 10
mysystemmodule!JMSserver02@UDQueue01 10
But when try to listen message from these queue, it is listening from one server, for which URL given to connect.
mysystemmodule!JMSserver01@UDQueue01 0
mysystemmodule!JMSserver02@UDQueue01 10
untill I connect to other server by giveing its URL, will not able to access other message left on the queue.
Solutions that tried
1) we have tried give both server URL coma sparated in provider URL
we need to configur same scenario for 5 managed server with 3 listener on other servers.
Do any one have solution for this.

You need to have:
1. Consumers connected to each UDQ member
OR
2. If no consumers in some of the members is expected, you can configure Forward Delay (specify the amount of time, in seconds, that a queue member with messages, but with no consumers, will wait before forwarding its messages to other queue members that do have consumers):
http://docs.oracle.com/cd/E12839_01/apirefs.1111/e13952/taskhelp/jms_modules/distributed_queues/ConfigureUDQGeneral.html
For example you can set it to 10 (10s)

Web Proxying to a WebLogic Cluster using the HTTPS protocol

Hi all,
I am recently involved into JWS proxying to WebLogic Cluster.
I don't have any technical problems at the moment but "conceptual" problems, that is:
- my jws proxy server should connect to a WebLogic Cluster through a Bea plugin configured wish SSL parameters;
- my jws proxy server should pass the incoming request using a load-balancing algorithm among the two nodes of the cluster, that are actually installed on two different machines;
- the jws proxy server doesn't seem to accept multiple certificates.
My question is: how can I configure my proxy plugin to route the incoming requests to my WebLogic Cluster using the https protocol? As a matter of fact, each certificate should be hostname dependent, and it looks like that the proxy plugin doesn't accept a multiple certificate configuration (and it should actually match the CN entry in the certificates with the actual hostnames of the nodes).
Any hint?
Thx a lot,
Luca

It is supported in 5.2

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 you

Answers :-
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.

Can we specify frontend host at web app level?

Hi,
We previously specified the frontend host in cluster settings. (same for all web apps)
Now we want two (portal) web applications deployed in the same cluster to have two different frontend host settings. Is it possible?
Thanks,
Mehmet

What a crock. Sorry, guy, but I am very technical. I know exactly what you
can and what you can not do on a website. I also know that there are very
simple methods for designing with all of the mainstream popup blockers in
mind.
So your scripted response may placate the non-technical masses. But those
of us who know better understand exactly what a poor job has been done on
your download site. I can give you 4 methods to fix the site right off the
top of my head! I won't do so because certainly any web developer capable
of creating your site knows just as much as I do about making this stuff
work.
The problem is not lack of technical knowledge. It is more fundamental -
and honestly what many programmers struggle with. Getting into the shoes of
the users. Getting out of geek mode and into usability mode. I mean hey,
it is fun to build all of the gizmos, not so much fun to add basic links.
As far as getting the download goes, I already have it. My point is that I
shouldn't have had to go through multiple steps. One very simple fix is to
just put the direct link onto the final instructions sheet. This is the
route web developers have selected for many other download sites.
So rather than sending me bogus answers, why don't you send my comments to
the people who manage the web development team. That is where the problem
will get fixed.
Thanks!

Exploded (hot) deployment on a Weblogic cluster

AFAIK, exploded hot deployment on a Weblogic cluster is not supported through OEPE.
When deploying an application on a cluster, each change, no matter how small, forces you to republish these changes, ultimately causing the application to be redeployed by OEPE. Turnaround time for this (depending on the app) can take some time.
Is there a workaround available for this ?
I'm looking for a way to minimize the turnaround time between developing code, and actual seeing the code changes on the screen. The requirement however is that deployments should be possible on a managed instance / cluster (non AdminServer).
Does Oracle Weblogic support such "hot deployment" capabilities from an IDE like Eclipse ? Does anybody here have such a process in place ? (perhaps using ant / maven2 tooling)

Hi
I want to clarify that the application has to be deployed to a cluster of two managed servers, amandad_Server_1 (On Windows server hosting console) and amandad_Server_2 which is running in other Windows server.
I deployed the application following your recdommendations and the resulta is as follows:
Windows server (running the console)
1 EAR file was copied to ... \user_projects\domains\amanda_domain\servers\amandad_Server_1\stage
2. The application files extractected from the EAR files were copied to   \user_projects\domains\amanda_domain\servers\amandad_Server_1\tmp
Windows Server not runn ing the console
No files were copied to neither
... \user_projects\domains\amanda_domain\servers\amandad_Server_2\stage
     \user_projects\domains\amanda_domain\servers\amandad_Server_2\tmp
Questions
1 Windows server not running the console the files were not copied....What might cause this behaviour....? how to fixi it...?
2. Do I have to manaully copy the files to folders
...\user_projects\domains\amanda_domain\servers\amandad_Server_2\stage
   ... \user_projects\domains\amanda_domain\servers\amandad_Server_2\tmp

Creating Virtual Hosts in Weblogic 8.1

How to create Virtual Host in WLS 8.1
(i.e) , if i type WWW.myapplication.com, the WLS8.1 should fetch the page........

Use the Administration Console to define a virtual host.
Create a new Virtual Host.
Expand the Services node in the left pane. The node expands and displays a list of services.
Click the virtual hosts node. If any virtual hosts are defined, the node expands and displays a list of virtual hosts.
Click Create a New Virtual Host in the right pane.
Enter a name to represent this virtual host.
Enter the virtual host names, one per line. Only requests matching one of these virtual host names will be handled by the WebLogic Server instance or cluster targeted by this virtual host.
Click Create.
Define logging and HTTP parameters:
(Optional) Click on the Logging tab and fill in HTTP access log attributes (For more information, see Setting Up HTTP Access Logs.)
Select the HTTP tab and fill in the HTTP Parameters.
Define the servers that will respond to this virtual host.
Select the Targets --> Servers tab. You will see a list of available servers.
Select a server.
Click Apply.
Define the clusters that will respond to this virtual host (optional). You must have previously defined a WebLogic Cluster. For more information, see Using WebLogic Server Clusters.
Select the Targets tab.
Select the Clusters tab. You will see a list of available clusters.
Select a cluster.
Click Apply.
Target Web Applications to the virtual host.
Click the Web Applications node in the left panel.
Select the Web Application you want to target.
Select the Targets tab in the right panel.
Select the Virtual Hosts tab.

Could you please explain why it happens, and what should I do to resolve this issues ?
Many Thanks,

Hi, Gene
Thank you for the response. I will send you our full log files and thread dumps.
I just want to give you more details about our cases :
1. This only happened without starting cache servers (com.tangosol.net.DefaultCacheServer).
2. And our application which are running on weblogic cluster will just call "CacheFactory.getCache("XXX")", and running as the Tangosol DataClient.
3. All weblogic member servers will be up running successfully if our cache servers are up running.
Also I tried to test another case :
Suppose all weblogic instances and cache server instances are up running. Now I trying to restart (kill weblogic instance process and restart) one of the weblogic member, It will up running successfully only if add some sleep times after killing weblogic processes and restarting it. Looks like tangosol cluster need certain time to aware the member has left cluster, then the restart process will be successful.
Questions :
1. Should we start our weblogic cluster only after cache server cluster is up running ?
2. How do we decide how many time we should wait before start new process to join the cache cluster ?
Could you please help to explain this one for me and let us if there anyway we can do to avoid the problem.
Many Thanks !!!

No communication between the two nodes in weblogic cluster

Hi All,
We have installed weblogic cluster in our environment(LINUX 64-Redhat.5).On one node admin server ,managed server1,on second node we have managed server2.When we try to deploy application on one node it is not getting reflected in othe node.We have ran datagram test to check communication between 2 node.
Here we observed that listener and pulisher are picking wrong IPs not the server Ips.
can any one explain why and what is the problem.
thanks,
sudheer.

Hi Sudheer,
While performing the datagram test you mention the ports and ip so I am not sure how they are picking wrong ip and port. Follow the instructions to perform the test http://coherence.oracle.com/display/COH35UG/Performing+a+Datagram+Test+for+Network+Performance
Re the deployments, you need to ensure that multicast is enabled in your environment and both your managed server are in the same subnet otherwise you need to specify WKA for unicast communication. I am assuming that you are building SOA infrastructure as it internally uses Coherence for deploying applications and you can follow the instructions http://download.oracle.com/docs/cd/E15523_01/core.1111/e12036/extend_soa.htm#CHDEAFJH else use the intructions as mentioned here http://download.oracle.com/docs/cd/E17904_01/web.1111/e13709/features.htm
Hope this helps!

Timesten database driver is not supported in Weblogic cluster mode??

Does anybody encounter this situation??
I have 2 managed server in a Weblogic cluster domain and there is DataSource for them.
In each managed server, I setup Timesten client correctly to connect to Timesten Oracle DB cache server.
But when we start each of managed server, I will get exception:

But if I create a standalone domain, still use the same datasource(still this timesten server), weblogic server can start successfully.
