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 :-()
[Thu Nov 24 15:46:40 2005] [notice] Apache/2.0.55 (Unix) configured -- resuming normal operations
[Thu Nov 24 15:46:56 2005] [error] Port number specified in WebLogicCluster parameter specified in httpd.conf is not an integer less than 65535

    Thanks Ravi,
    i have already gone through http://docs.oracle.com/cd/E12840_01/wls/docs103/plugins/apache.html.
    In my case "mod_wl_22.so" was not available but i downloaded this p10051826_1033_Generic.zip file from where i got that file and make it available in the modules directory, changed the file permissions (using chmod 755 mod_wl_22.so) and also changed the httpd.conf file as below :

  • 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.

  • ACFS recomandations for weblogic cluster

    Hi,
    Can some one help me to findout material(step by step) for ACFS usage with weblogic clustering.
    Originally I started thread here :
    Re: ACFS recomandations for weblogic cluster
    Thanks in advance for valuable time
    Datla

    The first question you need to ask yourself is for what purpose do i need this type of filesystem when using a WebLogic Cluster?
    The first which comes to mind is the migration of so-called singleton service, such as JMS Servers, persistence stores and JTA.
    For example, when a machine fails, we must bring the services, running on the failed machine, up on other machines. The JTA
    service plays a critical role in recovery from a failure scenario where transactions are involved. In-flight transactions can hold locks
    on underlying resources. If the transaction manager is not available to recover these transactions, resources may hold on to these
    locks for a long time. This makes it difficult for an application to function properly. JTA service migration is possible only if the server's
    default persistent store (where the JTA logs are kept) is accessible to the server to which the service will migrate.
    This where a shared storage mechanism comes into play - to store files which need to be accessible from every server. The concept
    of ACFS which is useful in this scenario is the mount model (http://download.oracle.com/docs/cd/E14072_01/server.112/e10500/asmfilesystem.htm#CACJGEAC)
    To set-up a mount point you can follow the steps presented here: http://download.oracle.com/docs/cd/E15051_01/wls/docs103/cluster/service_migration.html#wp1049463

  • How to configure a error queue for weblogic jms topic

    Hi guys.
    I want to configure a error queue for weblogic jms topic. Wanted: The message goes to error destination when messages have expired or reached their redelivery limit.
    1. using jms transport configure proxy service:
    Retry Count :3
    Retry Interval:10
    Error Destination: ErrorTopic
    Expiration Policy: Redirect
    I tried use the proxy service to consume message from the jms topic . and generation an error in the proxy message flow. But the message didn't goes into the error topic.
    Any suggestions for this topic? Can anyone provide some helps or any useful links.
    Thanks in advance.

    I want to configure a error queue for weblogic jms topic. Wanted: The message goes to error destination when messages have expired or reached their redelivery limit.
    1. using jms transport configure proxy service:
    Retry Count :3
    Retry Interval:10
    Error Destination: ErrorTopic
    Expiration olicy: RedirectUnlike File/SFTP, JMS proxy service definition does not have the concept of Error Destination. To accomplish similar functionality go to JMSQ on (for which proxy is configured) server console (http://localhost:7001/console) and configure the Error Destination. Following URL will help in how to configure JMS Q.
    http://edocs.bea.com/wls/docs103/ConsoleHelp/taskhelp/jms_modules/queues/ConfigureQueues.html
    http://edocs.bea.com/wls/docs103/ConsoleHelp/taskhelp/jms_modules/queues/ConfigureQueueDeliveryFailure.html
    I tried use the proxy service to consume message from the jms topic . and generation an error in the proxy message flow. But the message didn't goes into the error topic.If every thing is configured as per above step, then the after retries, the weblogic server will put the message into JMS topic configured. Your proxy will receive from this topic.
    Let me know if we are not on same page.

  • How can i configure Distributed cache servers and front-end servers for Streamlined topology in share point 2013??

    my question is regarding SharePoint 2013 Farm topology. if i want go with Streamlined topology and having (2 distribute cache and Rm servers+ 2 front-end servers+ 2 batch-processing servers+ cluster sql server) then how distributed servers will
    be connecting to front end servers? Can i use windows 2012 NLB feature? if i use NLB and then do i need to install NLB to all distributed servers and front-end servers and split-out services? What will be the configuration regarding my scenario.
    Thanks in Advanced!

    For the Distributed Cache servers, you simply make them farm members (like any other SharePoint servers) and turn on the Distributed Cache service (while making sure it is disabled on all other farm members). Then, validate no other services (except for
    the Foundation Web service due to ease of solution management) is enabled on the DC servers and no end user requests or crawl requests are being routed to the DC servers. You do not need/use NLB for DC.

    Hi Ye,
    I noticed this afternoon that Oracle's refering to Oracle WebLogic 10.3.1 as "Oracle WebLogic 11g".
    Know this comes as no surprise to you, but when I tried to install Oracle BPM 10gR3 Enterprise on WebLogic 11g (WebLogic 10.3.1) this afternoon it failed. A friend pointed out to me that Oracle WebLogic 11g does not support the DataDirect JDBC driver. Since Oracle BPM Enterprise 10gR3 uses this driver to connect to both its Engine database and Directory Service databases, he's thinking this might be the cause of our problem.
    It would be worth verifying this with Support. Here's what I think they'll point you to. The Oracle BPM 10gR3 release notes(http://download.oracle.com/docs/cd/E13154_01/bpm/docs65/relnotes/release_notes_OracleBPM10gR3.htm#N65589) indicate that the only WebLogic application servers supported are Oracle WebLogic 10.3 (10gR3), Oracle WebLogic 10.0 MP1.
    Again, talk to Support, but I don't think there's a workaround. The only thing I think you can do is to uninstall WebLogic 10.3.1 and then install WebLogic 10.3 if you want to install Oracle BPM 10gR3 Enterprise on it.

    Webserver plugin
    I want to know about the configuration of machines. Can IIS and weblogic be on the same machine or different machines????  Where i have to install the plugin????
    I am not able to find this in the above documentation.
    My environment is:

    2) Forms and Reports 11gR2 are installed on this weblogic server
    3) Apex Listener is also installed on the weblogic which communicates with a different db server.
    4) I also want to install JDeveloper and ADF on the same weblogic server and call applications developed in ADF (like jsp page) from Microsoft IIS website.

  • Configuring a virtual host in Weblogic

    Hi,
    I created a virtual host in Weblogic but it doesn't work. I followed all of the steps from the Weblogic website.
    The default URL for my application works, http://localhost:7001/abc_application but when I try using the new virtual host I get an error,
    http://xyz.com:7001/abc_application. I applied the virtual host to my Weblogic Managed Server and also to a deployed application. What else needs to be done outside of Weblogic for this to work?
    Sorry for the cross-posting.
    Thanks,
    Annette

    Hi Annette!
    Have you modified the hosts file for your machine to add an entry for xyz.com to map back to 127.0.0.1?
    What sort of errors are you getting when you try to access the virtual host? Can you post a snippet from your log file?

  • Front End Tool for JSP

    I'm trying to develop a commerically viable front-end to an existing JSP system.Are there any tools available that make the task of creating a front end(i.e. HTML,XML) easier.
    For example, nice headers/tabs at the top of each page while keeping usability at a premuim??

    That's a difficult question to answer off the top of my head.
    Are you looking for some software that allows you to import a JSP based application into it, with the intention of modifying those so they look nicer?
    Or are you looking for a tool that will let you build nice looking pages then spit those out as JSPs or XMLs?
    Either way, my reply would be NO? The userbility aspects are things your organisation has to invest time in (designers, PR folks, communications, page developers, info architects, etc). Translating those thoughts into hard pages is where the HTML layer comes in, and there are no tools out there that can bring usability into web pages.
    You see what I mean?
    However, if what you are asking for is the availability of tools or editors to help you create the HTML you put in JSP files, then you are only one step away from your answer. There are several out there. Just look in http://www.download.com/Web-Page-Creation/2001-10247_4-0.html?tag=nav_dir for some of the most popular.

  • 720 GUI causing a problem in Front End editor?

    Hi all,
    We recently upgraded our GUI to 720 patch level 3.  Now I am finding that when I am in the ABAP New Front End editor I am having a problem with the Code Hint feature.  I used to be able to hit ENTERr when a STATEMENT was proposed to accept it but  that doesn't work anymore.  Has anyone else encountered this issue?  I have read the documentation on the Code Hint feature and reviewed all my settings.  I did learn from the documentation that you can also hit TAB to accept the proposed syntax.  I tried that and hitting TAB works.  Did they remove the hitting ENTER?  Just checking before I log this was SAP.
    Any info is appreciated.
    Thanks.

    Hi Mark,
    Yes, this feature is not available in the new GUI. We need to hit the TAB Button to achieve this.

  • Shared disk for weblogic cluster

    Hi Gurus,
    I've googled about the subject, but didn't find any specific.
    Could somebody explain,
    Is it possible/certified to create weblogic domain on a clustered file system (i.e. OCFS2)?
    I would like to build a cluster with common domain home.
    Regards,
    Mikhail

    Hi Saurabh,
    What is the best way to have some shared data
    within a cluster. This data needs to be in memory
    only, no need for DB persistence. But it can be
    upadted (in memory only) and updates should be
    visible to any of the servers with in the cluster.
    For example - I want to create a hashtable to be
    shared within cluster and the hashtable can be
    modified from time to time.Tangosol Coherence does just that:
    :: http://www.tangosol.com/coherence.jsp
    It even supports the same Hashtable API!
