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.

Deploy multiple instances of the same stateless session EJB

I have a stateless session bean.
The methods on the bean operate against DB tables.
Q: Can I deploy multiple instances of the same stateless session bean, but specify a different JNDI/datasource name in the deployment descriptor?
The method calls are all enclosed within a single invocation, just that I need to hit different databases (all with the same schema), and Id like to be able to lookup the EJB via a different JNDI name, and have the exact same functionality, just against different deployed datasources.
Does the spec allow/support this?
If not, any suggestions as to how to achieve this sort of functionality?
Im using JBoss 3.2.1 on Solaris, so Im not sure whether or not this is a JBoss "issue" or a limitation of the EJB Spec (or me being just plain wrong and trying to do something the "wrong way")

NickI haven't done it but judging from the deployment descriptors yes.
For example if I have two bounded datasources java:/Database1 and java:/Database2
Lets say I have a session bean called MySession, then in your ejb-jar.xml you would have (notice that the desc, display, and ejb-name are the only differences)
<session>
<description>MySessionAlpha</description>
<display-name>MySessionAlpha</display-name>
<ejb-name>MySessionAlpha</ejb-name>
<home>com.mycorp.MySessionRemoteHome</home>
<remote>com.mycorp.MySessionRemote</remote>
<local-home>com.mycorp.MySessionLocalHome</local-home>
<local>com.mycorp.MySessionLocal</local>
<ejb-class>com.mycorp.MySessionFacadeBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<resource-ref>
<res-ref-name>jdbc/DataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</session>
<session>
<description>MySessionBeta</description>
<display-name>MySessionBeta</display-name>
<ejb-name>MySessionBeta</ejb-name>
<home>com.mycorp.MySessionRemoteHome</home>
<remote>com.mycorp.MySessionRemote</remote>
<local-home>com.mycorp.MySessionLocalHome</local-home>
<local>com.mycorp.MySessionLocal</local>
<ejb-class>com.mycorp.MySessionFacadeBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<resource-ref>
<res-ref-name>jdbc/DataSource</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</session>
But now in the jboss.xml, we will have the following elements. What you may notice is that are bound to different remote and local jndi names. But the resource bindings are very different. The res-ref-name stays the same, but the jndi-name are different. I think this will work for you.
<session>
<ejb-name>MySessionAlpha</ejb-name> <jndi-name>ejb/com/mycorp/MySessionAlphaRemoteHome</jndi-name> <local-jndi-name>ejb/com/mycorp/MySessionAlphaLocalHome</local-jndi-name>
<resource-ref>
<res-ref-name>jdbc/datasource</res-ref-name>
<jndi-name>java:/Database1</jndi-name>
</resource-ref>
</session>
<session>
<ejb-name>MySessionBeta</ejb-name> <jndi-name>ejb/com/mycorp/MySessionBetaRemoteHome</jndi-name> <local-jndi-name>ejb/com/mycorp/MySessionBetaLocalHome</local-jndi-name>
<resource-ref>

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
Dipen

create 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.

You 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 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

allow for setting different names for the several services.

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
Madhu

Hi.
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

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.

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

Deploying Windows Azure Cloud Service to multiple instances

Hello folks,
Currently, I have Windows Azure Cloud service on one instance, if I move to multiple instances, will Azure deploy it to all instances during the time of deployment? Basically, the fact that there are multiple instances behind the Cloud Service will be transparent
to the whole deployment process, is that a correct understanding?
Thanks

Hi,
From my experience, all the instances in one cloud service were the same, and we just focus on the application and not the infrastructure. Refer to
http://www.windowsazure.com/en-us/services/cloud-services/ for more information.

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.

Is 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?

Then start individual weblogic processes using this config file.
