Weblogic 6.1 clustering on Linux

Hi,
 I have clustered two managed servers (one on solaris machine and the other on
 linux red hat 7.1). When I try to boot the cluster, WLS start fine on solaris
 but on the linux machine, I am getting the following message:

 Can somebody tell where the file weblogicunix1 is located? has this file been
 changed with WLS 6.1 on linux? If yes can you tell me the name of the new file
 so I can create the necessary link?
 Thanks again.
 Amen

Using the generic file to install the software on linux does not install this automatically.
 The bea support send me this file in an email. I believe for the time being, the
 software is not package properly.
 Thanks for your help.

Jsafe unsatisfied link error calling CyberSource credit card service for Weblogic Server 5.1 on Linux

Hi,
I'm running Weblogic Server 5.1 on Linux, when we make CyberSource credit card request, the server console shows errors: jsafe unsatisfied link: jsafe not found in java.library.path .....
However, when we run Weblogic Server 5.1 on Window 2000, it does not show any errors and goes well with CyberSource credit card services.
Anybody can help me?

Did you modify your scripts to actually use SP6?

Weblogic 6.0 clustering on Solaris

          I want to setup Weblogic 6.0 clustering on two solaris boxes. I do have a Weblogic

          1. Where do I get a multicast address from?
          2. The two Solaris boxes are in my DMZ with private IP's is it ok or do I need to
          have public IP's.
          3. How do I setup the cluster.

Unable to initialize Node Manager on Weblogic 11g (10.3.5) Linux env..

Hello,
I worked earlier on Weblogic 8.1 and after a long gap I am coming back to Weblogic Server.
And I tried to install & setup Weblogic Server 11g R1 (10.3.5). I successfully installed WL 11g on a Linux machine, configured the domain, and admin server without any problem. I created a managed server on the Console and tried to initialize the node manager to be able to start the managed server. I am getting the following error message repeatedly. And I did not select SSL connection, while setting up the environment.
Can someone help me resolve this issue?

Can you see what listen address you have given to Node Manager in console or in config.xml?
<machine xsi:type="unix-machineType">
<name>Servername</name>
<node-manager>
<name>Servername</name>
<listen-address>localhost</listen-address>
</node-manager>
</machine>
Another way to start Managed server is to use startManaged.sh script.

WebLogic 8.1 SP4 on Linux - thread dump does not work

I have setup WebLogic 8.1 SP4 on RedHat Linux AS 3.3 with Sun JVM (142_05). When I try to perform a thread dump using weblogic.Admin, I receive the following error in the stderr file. I have also tried the kill -3 but still no thread dump. Is there some trick to this ?
cannot load libary 'stackdump': java.lang.UnsatisfiedLinkError: no stackdump in java.library.path

I am getting the same error as well
cannot load libary 'stackdump': java.lang.UnsatisfiedLinkError: no stackdump in java.library.path
I am creating a simple domain using the domain config wizard and I hope all the PATH and LD_LIBRARY_PATH are set by the default scripts. But I am still getting this error.
But Kill -3 <PID> works though!
Is is a know problem OR am I missing something?!

Weblogic 5.1 Clusters

I am trying to find out information regarding to the setup of a Weblogic 5.1
          Cluster.
          I am in the process of reading the online docs as a start....
          Base components being currently utilised on 4.5.1 are:
          - Solaris version 2.6
          - Netscape version 3.6
          - Database version Oracle, 8i
          - JDK 1.2.1_03a
          Questions:
          What is the most popular cluster type used by vendors?
          Are there any specific requirements that define what is best for what
          circumstance?
          What implications exist if any for the clustered environment?
          Is there anyone out there that I would be able to speak regarding algorithms
          they may have implemented?
          Anyone have any statistical information about performance / load balancing
          etc?
          Anyone know any resources that may be able to suggest for me to investigate
          in the specific area of 5.1 clustering, or can anyone outlay any experiences
          please?
          I would really like to obtain stats / benchmark performance of differences
          between 4.5.1 and 5.1 as well?
          any help appreciated?

Clustering in Linux

As I know Oracle do provide a Failsafe Technology on Microsoft NT
Clustering Environment.
I want to know How can I do the same thing in Linux. OR How Can I
ensure that if my Oracle Database Server is down suddenly and I
can restart my database service with a minimum downtime. Is there
any solutions ?
null

You do not need to reinstall box 1.
Regarding the changes, they could be small if (and only if) the initial box was already prepared for RAC.
With this I mean
Do you have RAC software installed?
Are your datafiles already in a storage system that can be shared by both systems?
Have you already installed the datafiles on a supported cluster filesystem?
Do yo have an extra network card on the box for the comunication between the two nodes?
Installing a "supported" RAC is not put a box and plug two cables.
It is also the posibility of having also SAP enqueue replication configured ...
You can find some documentation on SAP on Oracle

Exception weblogic.utils.ParsingException in redhat Linux (include JSP)

Hi,
We have a lot of application (war,ear) deployed in Windows XP Server, Sun Solaris with WebLogic Server 7.2 and shows no problem, but now I installed the same applications in WLS SP2 in Linux RedHat 9, and deployed I haven't had any
problem in doing so, but I get an error when I try to view these applications in the browser.

<QUESTION>
I have a problem with creating a separate working directory for Weblogic
Commerce Server where I can do development. These are the errors that I
can when I try to access a particular portal,
I have created a separate user account for this purpose while all the
main Weblogic stuff are still under /usr/local/weblogic and
/usr/local/weblogicac. I can access individual jsp pages through
absolute URL but then I use a portal name to access the portal, it
throughs those exceptions. Does anyone have similar experience when
trying to create a separate development environment using the same
installation and license? Do you have to do a new installation?</QUESTION>
<ANSWER>
Theoretically, the working directory JSP for the portal implementation that
tells the portal framework where to find your portal pages and the BEA
WebLogic Portal pages.(This page is qualified from yourDocumentRoot as
defined in the weblogic.properties file.)
Example: workingdir=/portals/myPortal/
You need to register the new working Dir in Weblogic.Properties files and
restart your Application Server after you create your new working Dir.
It is not easy to say with the situatrion that you described. Please check
the link http://edocs.beasys.com/wlac/portals/docs/portal.htm#getting for
details to create working Dir step by step. It may meet your needs. You may
also check http://www.weblogic.com/docs/admindocs/properties.html#jsp for
further information about JSP working Dir setting.
Please try it again and post the result if it's possible.

Which JDK to install weblogic 10.3.3 in Linux 64 bit machine.

I jave a Linux 64 bit box. I am trying to find out suitable java env for installing weblogic. JDK 64 bit, downloaded from Sun, is raising noClassDefFound for java/lang/object. Not sure if my platform is not correct or that .bin file is wrong. Can I use jrockit for installation?

I tried installing 10.3.2 on 64 bit linux with the Sun JDK and had issues (smart update didn't work). I retried with JRockit and it installed just fine and smart update worked. I haven't created any domains though as I'm planning on installing OEM Grid 11g on it.

Question: WebLogic 4.0 Clustering on Solaris 2.6

I've read through several of the postings about Clustering Weblogic Servers
 but there are still a couple of points that aren't clear. We have a Java application
 that is going to use two Weblogic Application servers to go against a Sybase
 database. We decided to use two Single CPU Weblogic servers in a clustered
 configuration for load balancing and in the event one goes down or needs to
 be taken off line. Each server currently has two NIC's. One NIC is connected
 to the LAN where our client PC's are located and the second NIC is going to
 connect to an isolated Network for the Multicast communication and an NFS
 mount for the Weblogic servers. Eventually we might add a third NIC in each
 server that will connect to the network that the Database servers reside on but
 for now they will use the same NIC as the Client PC's.
 The part that isn't clear is the portion about the Multicast addresses. In some
 messages people try to assign and bind the Mutlicast address to the NIC and
 in others they just use a normal IP address and it looks as if the Mutlicast
 address is just configured in the Weblogic properties file. I would like to use
 the second NIC in the servers for the NFS mount and the Multicast communication
 between the servers. Is there anything special to configure this on a SUN solaris
 server? If you have any ideas please let me know.
 Regards,
 Robert


There is a bug report that makes me think this is broken in Solaris 2.6, but
 in theory the following should work:
 Get rid of '/usr/sbin/route add -interface -netmask "240.0.0.0" "224.0.0.0"
 "$mcastif"' in /etc/init.d/inetsvc which sets the "standard" multicast
 address space starting at 224.0.0.0 with a mask of 240.0.0.0.
 Add to your taste:
 /usr/sbin/route add -interface -netmask "255.0.0.0" "235.0.0.0"
 "host1.foo.com"
 /usr/sbin/route add -interface -netmask "255.0.0.0" "236.0.0.0"
 "host2.foo.com"
 /usr/sbin/route add -interface -netmask "255.0.0.0" "237.0.0.0"
 "host3.foo.com"
 Where host1.foo.com, host2.foo.com, etc. are in your local hosts file and
 are set to the local IP address of the interface you want to bind each
 multicast class C address space to.
 netstat -r should give you the visual confirmation that things are
 configured correctly...
 Try snoop on a different machine to see if things are working on the wire:
 snoop -d hme0 multicast | grep -v ETHER
 Where hme0 is the ethernet interface in the proper Ethernet layer 2 domain
 that you want to analyze. Make sure you see the traffic you expect.

Exception weblogic.utils.ParsingException in redhat Linux

Hi,
We have a lot of application (war,ear) deployed in Windows XP Server, Sun Solaris with WebLogic Server 7.2 and shows no problem, but now I installed the same applications in WLS SP2 in Linux RedHat 9, and deployed I haven't had any
problem in doing so, but I get an error when I try to view these applications in the browser.
The message is:
9,name=hubcontrol,context-path=/hubcontrol)] Root cause of ServletException
weblogic.utils.ParsingException: nested TokenStreamException: antlr.TokenStreamIOException
at weblogic.servlet.jsp.JspLexer.parse(JspLexer.java:961)
at weblogic.servlet.jsp.JspParser.doit(JspParser.java:90)

at weblogic.servlet.jsp.Jsp2Java.outputs(Jsp2Java.java:119)
at weblogic.utils.compiler.CodeGenerator.generate(CodeGenerator.java:258)
but, I know the problems is <%@ include file="xxx" %>, WL don't support <%@ include file="/xxx" %> in linux....I have many applications WAR, I cannot change them for a Linux version.... does not exist another alternative?
Thanks a lot,

<QUESTION>
I have a problem with creating a separate working directory for Weblogic
Commerce Server where I can do development. These are the errors that I
can when I try to access a particular portal,
I have created a separate user account for this purpose while all the
main Weblogic stuff are still under /usr/local/weblogic and
/usr/local/weblogicac. I can access individual jsp pages through
absolute URL but then I use a portal name to access the portal, it
throughs those exceptions. Does anyone have similar experience when
trying to create a separate development environment using the same
installation and license? Do you have to do a new installation?</QUESTION>
<ANSWER>
Theoretically, the working directory JSP for the portal implementation that
tells the portal framework where to find your portal pages and the BEA
WebLogic Portal pages.(This page is qualified from yourDocumentRoot as
defined in the weblogic.properties file.)
Example: workingdir=/portals/myPortal/
You need to register the new working Dir in Weblogic.Properties files and
restart your Application Server after you create your new working Dir.
It is not easy to say with the situatrion that you described. Please check
the link http://edocs.beasys.com/wlac/portals/docs/portal.htm#getting for
details to create working Dir step by step. It may meet your needs. You may
also check http://www.weblogic.com/docs/admindocs/properties.html#jsp for
further information about JSP working Dir setting.
Please try it again and post the result if it's possible.
Thanks

Has Weblogic 10.3r support OS - Linux (Redhat) x86_64-Bit xeon fully?

Hello
We have new servers (64-bit Xeon processors), we want to install OS (Redhat Enterprise 5 64-bit) . But
i am not sure, i am afraid of new technology platform (jdev11g and weblogic 10.3r ) can be a problem.
Has Weblogic 10.3r support or version OS (Redhat Enterprise 5 64-bit) fully? i want to try weblogic 10.3, but in the download page of oracle we have server103_linux32.bin file. i want to ask this, linux32.bin means that this version only can use on linux 32-bit or not ?
Thanks for interest
Mehmet Özkan YAVUZ

Hi, Mehmet.
Yes, it is supported. However, you need to use the generic installer
Here's the supported configuration page:
* http://e-docs.bea.com/platform/suppconfigs/configs103/103_over/prod-info.html#1085783
Here's a related thread on the generic installer
* Weblogic10.3 installation influence ...

Does killing an instance of weblogic in a clustered environment hurt?

I just got moved to a group responsible for web hosting within the company that I work for. I was looking at how they do things with regards to weblogic and deploying/trouble shooting apps. They have many apps, each developed by a different person. All of the apps are deployed under the same clustered two instances of weblogic. To redeploy they kill weblogic then restart it, one instance at a time. They tell me that since weblogic is clustered killing one instance doesn't affect the users on the site. Also, they frequently do thread dumps saying that this doesn't affect the users experience either. Is this correct?

Did anyone found a solution to this problems. I have been seeing this issues for day I can figure it out.
It seems to be some sort of issue with credentials between my admin server and managed server1

Weblogic 4.5.1 on Linux and JDK2.0

Hi,
We currently use 4.5.1 on Linux with JDK 1.1.7b. Has anyone did the same
only with JDK2.0. I realize its not supported by weblogic on Linux, but
would like to know whether anyone has tried it anyway and how it worked out.
Thanks. TC

I develop and run WebLogic on Linux with IBM's JDK 1.1.8.
Sun and Blackdown both have Java2 that are preliminary versions. I had
some problems with the Sun version, but the Blackdown 1.2.2 vm seems pretty
good.

Hi,
I am running WL 5.1 on RedHat 6.1 with the JDK 1.2.2 RC4 from Blackdown.
Touch wood, I haven't had major issues yet, other than really basic ones. Of
course, things get interesting when you begin to realise the little bits and
pieces that are supported on other platforms, but not on Linux, such as the lack
of apache support (even though it is forthcoming in 5.1 GA from what I
understand).
