Multiple JVM in one server

Hi,
Can we run multiple JVM's on one Solaris server with different applications configured for different JVM's or may be configure a memory intensive application to multiple JVM's.
Please let me know if this works and if there is any documentation for this.
Any help is greatly appreciated.
Thanks

Hi,
You have to change to <Listener port="9711"/> to <Listener port="9712"/>
Refere the below forum articles.

Multiple JVMs foe One WL6.1 instance

Hi,
Is it possible to attach multiple JVMs to an instance of WLS6.1
so that all JVMs will be self sufficient in serving client requests....
If it is possible then any pointers in that direction..???

Each WL server runs in one JVM. If you want to have 4 JVMs, then run 4 WL
servers in one cluster.

currently our App runs on 2 Iplanet App Server ( they are in Cluster)
and each App server has 2 VMs so we we are getting the feel of 4independent
App Servers but Physically we are able to get away with only 2 boxes.
We want to achive the same thing in Weblogic...

Multiple websites on one server

I've been trying to create multiple (two) websites on one server, with little luck. One sight works fine. I've tried creating a DNS entry for the new one, but I'm not sure what to set the IP to. I've tried many configurations of IP/hostname but nothing seems to work. Occasionally, the logs just disappear from the logs window.
I've read on here that it's possible to run multiple sites off of one IP, so I feel like that is not the problem. Ideally, I'd like to have one of the sites not exist in the System/WebServer folder. If I place the site folder outside of that folder, do I have to add its folder as a share point and/or modify its permissions?
Server version is 10.6.3

I'm going to distinguish the web browser (client), the web server, and the DNS server here, and will treat these as running on three separate computers. You might have one or more of those co-located on one box, adjust these references to your configuration as necessary.
The DNS translations are applicable only on the client; on the host box that is running with the web browser. The web server doesn't care about the DNS translation. The client needs the DNS to get the IP address of the web server, and it's off to the races from there.
Again, DNS translations are not relevant the web server. The particular web server that gets selected (Apache Virtual Host, what Apple calls a "Site") based on some information that is passed within the http (don't start working with https quite yet) connection from the web browser into the web server.
As for your DNS question, you'll probably want a CNAME (alias) entered in DNS database for the virtual hosts, even if you're awash with IP addresses. That alias must then match the name of the web server "Site". For testing, you can enter what amounts to CNAMES into /etc/hosts on the client, depending on your local set-up and your DNS server.
By default, the connections to all virtual hosts are via port 80. Stay there for now.
The web server selections are sensitive to the order of the "Sites" in the listing in Server Admin, too; you'll want the wildcard site (if you have that) at the end of the list.
Here are some of the basics: [Apache Tips: One Web Server, Multiple Distinct Web Sites|http://labs.hoffmanlabs.com/node/1282]. Comments on that are welcome.

Load multiple views in one server call

Hello,
We are developing SAPUI5 application with Master & Detail page pattern. On detail page, we have 7 tabs so to make it more manageable we have created 7 different views, one for each tab instead of writing all the code in one view. And one extra view which hold the tab and 7 views.
Now code is easy to maintain as we can go to specific view and do the changes instead of searching in one big view. But there is a new problem now, it take lot of time to load the detail section. It makes separate server call to load each view. Earlier it was loading detail section with one server round trip but now it is making 8 server round trips ( one for every view ).
So the question is, is there any way to load multiple views in single server trip?
Regards,
Vikram

You can do so but then at the time of defining the viewset you need to ensure the rowspan and colspan correctly to fit the first and the second view. More over the configuration also needs to be maintained correctly.

Harshit

Multiple JVMs on same server.

I have two JVMs on same server. Both JVMs are has been associated with different and independent applications. There were some errors reported by one JVMs. My question is
Is error reported from one JVMs could affect the another JVM/Application? If yes then what types of effect will be reported by other JVM or Application?
Thanks, Manoj

Recent Java versions employ "Class Data Sharing", which under some circumstances might propagate file corruption from one to the other. See

Can I do multiple installs on one server at the same time ?

Hi. we have a project where the basis group is under very tight deadlines. We are tasked with installing multiple SAP systems on the same server. Is it possible to install more than one SAP systems ( ie ERP, BI, EP, CRM ) on the same physical server at the same time. for example on analyst install ERP while at the same time another analyst do EP and so on.... Has anyone done that before and if so are there any issures. ( I put in a SAP note and got the response that this is not supported, but I just wanted to see if anyone had done it anyways )

Hi Dan,
Frankly simultaneous installations is not a great idea. There will be an enormous competition for resources. Then you also need to make available ports for carrying out the installations. Next it will involve high amount of coordination
What of course is more reasonable is the idea of hosting more than one SAP instance on the same physical server though again harware is a very important concern. It includes your hard disk space,memory,CPU and other generic hardware.
Please award points for useful answers.
Regards.
Ruchit.

Multiple Certs for multiple domains on one server

Is it possible with WLS6 and WLCS3.5 to serve up multiple domains with their own certificates?
i.e. https://www.foo.com and https://www.bar.com on the same box.

Hi,
for one WebLogic Server you can only specify one certificate. So to achieve
this you will have
to use different WLS instances for your domains - which is possible on the
same box.
Kind Regards

Multiple JVMs within app server - refresh of metdata not working

Hi guys.
We have an interesting scenario at present when running our application within a new test environment.
Our web-based application has the facility to refresh it's application metadata. This should mean that the next time the browser refreshes (or a user logs in to the application), the application will display based upon the refreshed metadata structure.
Previously, we have run our application on an app server with a single JVM without any dramas. ie. the refresh has always been reflected appropriately when viewing the application - as mentioned above.
However, we have installed the application in a new environment where the refreshing of meta data does not work consistently. That is, only about 50% of the time does the data refresh correctly. This can be seen by pressing the refresh button in an IE browser, so that the refreshed data appears approx. every second time the button is pressed. The only notable difference with this environment is that it runs 2 JVMs within the app server.
It seems that in this case, the 'old' data remains cached for the 'other' JVM, and that when the browser receives 'refreshed' data from the server, it does not always source from the same JVM.
This situation can be resolved by restarting the OC4J container, but this is not a desireable solution.
Is anyone aware of an OC4J parameter that can be set so that the 2 JVMs can run in synch so that both are refreshed appropriately when our meta data is cleared (refreshed) ? I don't believe this can be controlled within the Java source code, but I'm receptive to any other alternate solutions.
Thanks in advance.
Steve.

I'd like to embed multiple instances of the JVM within
a single, multi-threaded native server process. I'm
aware this was not possible with the Sun JDK in the
past.
Is this still true (for JDK 1.4.1 say)?Yes, this is still true.
If it's still not possible, are there any timetables
as of when it might be available? No.
Likelihood?Check the current list of JSRs at http://www.jcp.org.
Ah, btw: Is support for VM unloading (during
DestroyJavaVM()) available now?No.
>
In any case: does anybody know of a JVM
implementation
available for Linux which supports multiple VM
instances within a single process?Why do you need multiple VMs? Would multiple separate 'processes' within a single VM work? If so, have a look at:

Is it possible to have multiple emails on one server?

As the topic says, can i have more then one email service running off of the same server.
example:
[email protected]
and also
[email protected]
I have both domain names and have different websites for the different business. I need to give @something.us to some people and @somethingdifferent.com to others......
Thanks!
Adam

Yes, it's possible to do, but non trivial.
It's easier if every username exists in both domains (e.g. [email protected] is the same person as [email protected]), but it's still possible to do if they're different.
There are two approaches to doing it. Which one you use is up to you.
The first is to use Open Directory and add the email addresses as additional usernames for each account.
For example, you may have a user 'joe' who exists in domain2, so you'd give him the shortnames 'joe' and '[email protected]'. User 'bob' in domain 1 would have the shortnames 'bob' and '[email protected]'.
Note that both users exist in the main directory domain, which could be an entirely different domain.
The second method is the pure Postfix method and involves configuring postfix on the command line to support multiple domains. You'll essentially build a text file list of the names in the secondary domain(s) and will maintain this separately from the main server GUI tools. This optioni s covered in some depth in the Postfix Virtual Domains page.

Several JVMs in one server

Hi all,
In our test environment, we need to deploy our application several times to
run on several db.
If we create several server (ex : weblogic/myserver1 and weblogic/myserver2)
do they will use the same jvm?
If yes, is there a way to run them in several JVMs ?
Thanks in advance,
Cedric

Each weblogic runs in its own JVM. We have run dozens before on Sun
development boxes. Just make sure they do not try to attach to the same
port. ;-)

RE: How to have multiple application running under one server

          I have one server
          I have many application
          Question: Is it possible for me to have a weblogic properties file under each
          of this application.


If your question is whether you can run multiple instances of WebLogic
          (or multiple applications) on one server, the answer is yes. The only
          problem is, you must have a unique port for each of the servers to run
          on. I.e., they can not all run under port 80 which has obvious
          internet/network implications.
          This also means you have multiple weblogic.properties files etc. for
          each instance.
          We do this with WL5.1 on a Linux 2.4 kernel in developement to allow
          multiple developers run their own instance on one box.

11g Multiple Rpd on one BI server connecting to two different data marts

Hi
Did anyone tried and successfully implemented multiple rpds on one bi server. I have similar requirement in one of the clients place.
1. Install OBIEE 11g with vertical scaling( reason client doesnt want to spend extra money on additional server licenses) and would like to utilize the powerful existing servers.
2. Install 2 rpds on One BI Server and connect to two different datamarts.
3. Create two PS and provide two links to have two different reporting environments.
Appreciate with any pointers. I am very clear on Vertical Scaling and bumping up the Bi , PS and Java Hosts components. I saw a post with successful implementation of the same functionility in 10g and nothing in 11g. I already reviewed ritmanmeed blogs but did not give a complete picture of successfull implementation.
Thanks

Hi,
Yes, it is possible to have two different .rpds on one BI Server but then you need to set up two different Presentation Servers.

Multiple instances on single server

Hi all,
I have a Solaris 10 server with 2x dual core CPU's.
I am wondering if it was at all possible to install Business Intelligence Server on this single OS twice? And if it is, can I split the CPU between the different instances?
The reason for this is that I would like both production and test/development installed onto the same OS to cut costs. But I don't want the test/development instance to use resources that would affect the performance of the production environment.
Ideally I'd like the 2 instances, with the production instance using 3 cores, and the test/development instance using 1 core. If the RAM could also be split that'd be great.
Thanks for your help in advance.
Cheers

Yes, you can have multiple instances of Presentation Services (PS) ([see my blog posting for details|http://rnm1978.wordpress.com/2009/08/25/multiple-rpds-on-one-server-part-1-the-bi-server/]) which would let you split envs, but you'd do that with a single instance of BI server. I don't know if it's possible to run multiple BI servers
I don't think you should be trying to do this anyway, several reasons why not:
1) It's not supported to run multiple PS on one server. That should be reason enough not to do this on prod.
2) If it's not possible to run multiple BI Servers on one server then you'd end up running one BI Server with dev/test/prod RPDs - you'd never be able to bounce your BI Server for dev work without taking down prod
3) Any time you needed downtime for dev, you'd affect prod
4) Any patching you wanted to do on dev might affect prod
5) Any experimental work you do that crashes dev would affect prod.
If you only have the one box available to you for costs reasons then you should be looking into virtualisation of some kind, eg http://www.virtualbox.org
