Multiple instances of Weblogic on NT
Is is possible to run two instances of WebLogic on an NT server as
services? Specifically, I want to set up web server clustering on two
machines, but I am also going to be running another custom Weblogic
app that will access a backend database. I need to set up a separate
weblogic server for the database app outside of the clustering
weblogic webservers?
Thanks
Steve
yes u can run multiple instance of the service.
There is a parameter in install.exe where you can specify the name of the
service and in this manner you can have as many services as you want

registry keys that would be needed, and they aren't set up to
allow for setting different names for the several services.

Multiple instances of weblogic pointing to same public_html
Hi,
I am using Weblogic 5.1 and have successfully set it up to start multiple instances
of weblogic from one weblogic server(each instance has its own unique port).
Currently I have multiple instances of public_html (one for each instance). Does
anyone know what I have to do to point all instances of weblogic to a common public_html?
Many thanks in advance
Dipencreate a symbolic link that is called public_html that points to the common
docroot.

Configuring multiple instances of weblogic server 7.0 on single machine
Hi,
I am trying to configure multiple instances of weblogic server 7.0 on single machine
( sun Solaris 7). I tried to create everytime new domain. Can anybody help me.
Thanks in advance.
RaviYou can have several servers under one domain. No need to create a new
domain for each server. Just configure a server and make sure they are
listening on different ports. you are all set.

Multiple instances of weblogic server 6.1 running on the same machine
Hi,
I need to run two instances of weblogic server 6.1 running on the same
machine. I need one for development and the other one running the live
applications. I need two instances to be independent of each other. I am
running weblogic server as an NT service. So I need two servers to start
from the service so they are independent of each other.
Thanks
MadhuHi.
You can create new servers in your domain via the console. Be sure they are
listening to different ports, however. If your NT machine supports more than
1 IP address then you could alternatively bind each server to a different
address.
I'm not sure if this answers your question?

Multiple instances of weblogic server 5.1 on one node.
Hi,
We failed to start one instance on a node where we were able to start
another instance from another location.
We installed two instances of Weblogic server 5.1 on Solaris 5.7.
One at /usr/weblogic and another at /opt/weblogic. We were able to start
the /usr/weblogic instance in cluster mode. Then we stopped
/usr/weblogic instance and try to start another instance at
/opt/weblogic in cluster mode. But failed. We have similar directory
structure and files in both places except the weblogic.properties file,
which has different paths.
we are using JDK1.2.2 and got the following Exception
Exception in thread "main" java.security.AccessControlException: access

How to deploy multiple instances of WebLogic on the central server,wl6.0
I would suggest 2 domains each of them for it's own purpose, with an admin and a managed server with the same db connection name connecting to its own database. In this case the only difference is the domain name(has to be unique on a physical server) and the ports will have to be different on QA vs DEV. They could share the applications which can be located outside of both domains, but they will have to be deployed separately. if you want to work with different levels of code than you'll need 2 separate directories for storing the applications.
In fact you should test in QA only after DEV is done with development(?!).
In this situation watch the memory allocation as you can affect one of the domains by doing a lot of work/load on the other one. -
Clustering multiple instances on the same server
I've read reports of people clustering multiple instances of weblogic on the
same machine to better utilize the CPU of that machine.
So if I wanted to set up a cluster with four machines and two instances of
weblogic running on each (port 7001 and port 8001) , what properties do I need
to send into the startup command for the servers?
How do you set this up
Thanks in advanced.

Do this for all your four machines
1) Create dirs: cluster1, cluster2 under %WEBLOGIC_HOME%
2) Create dirs: cluster1\myserver, cluster2\myserver
3) create two startup scripts,
specify -Dweblogic.cluster.enable=true -Dweblogic.cluster.name=cluster1 (or
cluster2) in each script.
4) Speicfy weblogic.cluster.multicastAddress=IPAddr in
cluster1\weblogic.properties & cluster2\weblogic.properties, use different
IPAddr for these two cluster.
5) Specify weblogic.system.listenPort=7001 in
cluster1\myserver\weblogic.properties & weblogic.system.listenPort=8001 in
cluster2\myserver\weblogic.properties
6) If your machine is multi-homed, specify weblogic.system.bindAddr in
cluster1(and/or cluster2)\myserver\weblogic.properties.
my 2cents.

Clustering w/ Multiple Instances per server
For performance reasons, we want to setup multiple instances of weblogic on each server in our cluster configuration.How is this handled in a cluster configuration? Is each instance considered another server in the cluster? Does each require its on IP address, or is a seperate port sufficient for each? Also, is there a way to configure the cluster w/o using multicast - there's issues with supporing multicast on our backend network.Thanks, Rick
Sure, if JVM uses native threads and the application itself is well-behaved
concurrency-wise (very important!) it should be able to scale up on multiple CPUs.

Running Multiple Server Instance in Weblogic Server
Hi
I am using Weblogic 5.1.0 with SP6. I am trying to run multiple server
instances
of Weblogic Server. The one that comes by default is "myServer".
My question is if i were to create multiple server instances, do i need to
copy the
weblogic.properties file in each of folder corresponding to respective
application
server instance. I am not using Clusters.
Also if i need to include some classes or jar files in my application server
instance
classpath, how do i do it. cuz in weblogic.properties file i didn't find any
property
corresponding to classpath.
The classpath i need to set is for my creating a JDBC pool for connectivity
to my
AS400 DB2 database using the Type 4 (AS400JDBCDriver) Driver. Is there some
other way to do it.
Thanks in advance

Re: Running weblogic multiple instances on different ports
Hi,
I am planning to run multiple weblogic instances on different ports on the
same machine.
Is it possible ? If so, how ?
Details:
I am using IIS on the same machine. I am currently running weblogic on
7001 and 7002(ssl).
I dont how to run multiple instances. Please help me or guide me where I
can get documentation.
These two instances have to refer two different set of code bases ...
Please point me where I can more details.
Thanks in advance.
Sreedhar VIs it possible for the two instances on the same machine to participate in
the same cluster? I believe servers in a cluster must share the same port
(which is also used for multicasting). Does a virtual IP address need to be
configured?

them different ports to listen to. This is easily accomplished using theWLS

Then start individual weblogic processes using this config file.

Multiple instances of ECM 11g on one server
I've read a few posts about installing multiple instances of ECM 11g on one server, but I have a few questions. My current set up is
A single Windows 2008 Server R2 server
8 gb RAM
Weblogic 10.3.5
1 install of ECM 11g in the base_domain
Database is Oracle 11.2
I want to add another instance of ECM to this server, but when I went to run the RCU, I was not allowed to use the same prefix for my tablespaces. Is this expected? I'm fine with using a different prefix, I just was surprised to see that I couldn't use the same prefix on this install since I was using a completely different database.
Assuming I use a different prefix... do I just add a new domain for this additional ECM instance? Is there anything else I need to know?
Thank youI went to run the RCU, I was not allowed to use the same prefix for my tablespaces. Is this expected?Yes. It will create tables with the same name visible for a different database user (thus, the prefix).
do I just add a new domain for this additional ECM instance? Is there anything else I need to know?Actually, I think you can even install more instances to the same domain (this is more a question to Weblogic Server admins - I think there's been some posts recently on this topic). What definitely must be unique, is the port number. If you are OK with using different port numbers for your instances, it should be relatively easy. If you need the same port (e.g. 80 because of proxy limits), there are some ways how to redirect - it that case, two domains might be required. -
Multiple instances of Page Flows
I have a legacy application that I am working on migrating to Weblogic. The
legacy application allowed the user to have multiple windows of the same
module open at the same time. Users found this useful if they wanted to look
at two different records in the same module. For example, if you had a
registration app and you wanted to look at Joe's registration information
and Sue's registration. Is it possible to have two browsers within the same
session open and pointing to the same RegistrationController.jpf?
We currently have our form beans stored in the page flow which seems to
cause a problem as when we open another browser instance in the same session
pointing to the same page flow, the form beans from the first window are
overwritten. An approach we are possbily looking at is to store the form
beans in an object in the session and identify a set of form beans as
belonging to a particular window instance - perhaps by uniquely naming the
windows as they are opened.
Has anyone done this before with needing to have multiple instances of the
same page flow or multiple instances of different non-nested page flows open
at the same time?
MichelleHi Vijay,
Thanks for the reply, But that's not the right aproach.
I cannot change the application to stateless, Since the standard application where the page resides is statefull.
Also some of the business logic I cannot achive with stateless application
