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?
          Simon

Weblogic 6.0 clustering on Solaris

          I want to setup Weblogic 6.0 clustering on two solaris boxes. I do have a Weblogic
          cluster license. My questions are
          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.
          4. Any know issues with weblogic 6.0 clustering on Solaris 2.7.
          Thanks

          From your sys admin.
          Or use the default one. i.e. 237.0.0.1

          As long as they are static IP's , you should be fine

WebLogic 7.0 & WebLogic 6.1 Clusters on the same Sun Machine

          HI All !!
          can we have two different versions of Weblogic running on same machine in different
          clusters i.e. Weblogic 6.1 on one cluster with a different domain and Weblogic
          7.0 on another cluster with a different domain.
          Plzz reply ASAP...
          Thanx
          Nitesh


Yes, you can.

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.

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 Express and Clustering

Does weblogic express offer the same clustering options as weblogic server
 with regard to HttpSession replication?
 I'm looking at an architecture where the web container is separated from the

Combined-tier WebLogic Cluster (two clustered instances)

Hi guys,
How can I realise it?

Is it right steps?

 In the case of WL6 and WL7 clustering, if the requests from the same user jump
 around different instances, we experience this kind of session loss problem very
 frequently. I am not sure if this is the same case for WL5. The idea is, find
 a way to make sure the requests from the same use always hit the same instance
 unless it is dwon.

 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.

 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.

More questions about WebLogic 7.0 clustering

 Hi Folks,
 I have weblogic 7.0 spX in my environment.
 Machine A(7001) contains AdminServer and Machine B(7002),C(7002) are managed servers.The
 entire configuration is in Machine A config.xml file.The config.xml file of Machine
 B and C have only server information.
 I created a cluster in Admin Box A and added Managed B and C into the cluster.Using
 iPlanet as a web server,"Cluster Address" have machine B and C ip:port.
 Q1: The cluster information is available in only AdminServer A config.xml file.If
 the whole box(sun solaris) goes down, what will happen to managed servers and
 cluster?
 Q2:We deploy an .ear file in Admin Server A and restart the service.As per the
 weblogic document, it should deploy the .ear automatically on managed box's.It
 does.But I don't see the whole .ear file in Machine B and C.Instead I am seeing
 the content of .ear file in exploded format.Why?
 Thank You,
 - Lara


 Hi Lara,
 There is patch available for this for 7.0 and this is fixed in sp2 and higher.
 If you are in the lower version just go to ".internal" folder in the managed server
 boxes and delete the console.war (after everytime you restart your mgd severs).
 I know this is dirty. but this is a work around

Oracle Weblogic Load Balancing/Clustering

Can anyone tell me what the recommendation from Oracle is on how to best set up load balancing?
We currently use the configuration.properties file to identify the 2 servers we load balance. We will be implementing additional servers in the near future and we were wondering if this is the best way to load balance 4 or more weblogic servers or if there is some other way.
We set up one cluster address to utilize these servers and use a separate hardware load balancer device.
HRDEV\webserv\hrdev\applications\peoplesoft\PORTAL.war\WEB-INF\psftdocs\hrdev\configuration.properties
# To enable jolt failover and load balancing, provide a list of application server
# domains in the format of; psserver=AppSrvr:JSLport,...
# For example: psserver=SERVER1:9000,SERVER2:9010,SERVER3:9020

As this is peoplesoft specific configuration
Please try positing here:

IPlanet 4.1 - Weblogic 5.1 Clustering

Query 1:
          The libproxy.so proxy plugin seems to slow down the response. Anyway to tune it?
          Query 2:
          I have a servlet in iPlanet which upon receiving the request manages the Session and pass the request to the Weblogic Cluster using the proxy plugin with the help of RequestDispatcher. But i get an error in the iPlanet Server log as
          wl-proxy reports: IO error reading client POST data at line 314 of proxy.cpp, system error: 'Resource temporarily unavailable'
          How do i get rid of this?

Weblogic Admin Server Clustering

I am pretty new to WLS and was going through the doc on Clustering. It talks abt clustering managed servers.
Is there a way to cluster WL Admin Server,for eg : I fee I will not be able to access admin console if admin server is down.
so do we need to cluster Admin server also.
thanks

Only one admin server is possible within a particular domain.
The managed servers will continue to operate normally without the presence of the admin server process, presuming that that the machine(s) hosting the managed servers are still alive.
Run your admin server on a physically separate host than you use for your managed servers. In addition to not impacting your managed servers in the case of an admin server outage, this also makes it easier to control access to your admin server since you can restrict access to the entire host more closely than on the managed servers' hosts.

Urgent and intresting:weblogic JMS in CLustering

Hi all,
I deployed one application in two different servers(server1,server2) in a weblogic cluster.my application having one MDB .MDB also deployed on all servers.I am sending messages to server1 only by creating Initialcontext as follows.
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, "t3://10.20.30.18:7001");
return new InitialContext(h);
My question is:
1)is there any possible to consume that message by
server2(t3://11.22.33.20:7001) MDB.eventhough iam not putting message on this server.
2)if it is possible then how can i prevent.
3)does connectionfactory/destination(queue) sharable.
Problem faced:
we deployed application 2 days back,first day only server1 MDB consumed Messages,second day server2 MDB started consuming meaasges. we are calling some code from outside of application,we setup that one in only server1,if server2 consumes means it is throwing exception.
we are breaking heads how server2 consuming Messages.

Weblogic and OBIEE clustering.

Dear all,
Actually this is my first time to work with OBIEE 10G cluster , i successfully configured the following :
(1-)configured ( NQSConfig.INI, NQClusterConfig.INI ,odbc.ini, and instanceconfig.xml) successfully for each linux box.
(2-)Test is done for each node and yes all of the log files ensure that the cluster in working fine, also i am able to access the answers per each node in the cluster.
BUT
The question now is how to configure these nodes to be hosted with weblogic as one node (single URL)
(as simple talk what is the URL should i give to the end user to access the cluster not seperate machine) ???
I read this post
http://forums.oracle.com/forums/thread.jspa?threadID=1123127&tstart=-1&messageID=4568624
but still NOT GET FULL understanding for the solution please,
provide simple steps to configure the weblogic to handle this issue.
Thanks inadvance......................

sorry about this error for error the browser repeating the same post, the browser does not redirect me to the fourm page , may i ask the moderator to delete the other 3 posts
