Mulitple instances of same VI on same machine

is this possible?
if so how?
when i try and open the same vi on my machine it justs goes back to the
previously opened one..

Yes but ...
(1) If your VI has front panel controls
One way is to make a physical copy with a different NAME. I believe
shortcuts may work. You will need to be careful about sub-VIs tho.
I have also fiddled with function nodes but I am not quite sure if those
will work or not
Finally, the best way of doing this is to get the application builder
option and compile the VI. Once that has happened the VIs become
independent and you should be able to run any number of instances of the
executable.
(2) If your VI does not have front panel controls and you just wish to
use the same sun-VI in multiple VIs or multiple parallel instances in the
same VI, there is an execution option "reentrant" that
will allow this.

Multiple WL instances on same machine with multiple clusters

Hi,
          I am wondering if it is possible to run two separate instances of WL on a
          single machine, with each instance belonging to a separate cluster? The
          machines are not multi-homed, so each instance must listen on a separate
          port.
          Our current architecture looks like this:
          4 web servers running NSAPI WL plug-in
          3 app. server boxes running WL 5.1 SP2
          I would like to start multiple instances of WL on each app. server to better
          utilize the hardware, and would like each instance to be part of a separate
          cluster.
          My questions are:
          1. Do I have to have a separate multicast address for each cluster, or can
          I use the same address since the clusters are on different ports?
          2. In the NSAPI plug-in, you simple specify a list of all the servers for a
          cluster. Are there any issues with having the machine/port names in this
          list belonging to different clusters?
          Thanks,
          Bob

          Yes, you can. FYI, in addition, each cluster use different multicast
          address.

Configuring Data Guard on 2 different instance in same machine

Hi All,
I am new to the Data Guard concept. I am using Oracle 10g (Release 10.2.0.1.0) in Windows 7 environment . I have created 2 database instance its running fine.
For testing purpose, Is it possible to implement Data Guard concept between 2 instance in the same machine? whether it will impact any problem?
Thanks & Regards
Sami.

You would use the same one. That is, you would not have a separate tnsnames.ora and listener.ora.
What I was trying to say is you still need to add the SID_LIST_LISTENER lines that Data Guard uses
Example
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(PROGRAM = extproc)
(SID_DESC =
(global_dbname = PRIMARY_DGMGRL.uservices.umn.edu)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(sid_name = PRIMARY)
TNS Example
STANDBY =
(DESCRIPTION =
(SDU=32767)
(SEND_BUF_SIZE=2092500)
(RECV_BUF_SIZE=2092500)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = HOSTNAME)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = STANDBY)

How to create multiple Oracle 9i instance on same machine?

Hi Gurus,
I would like to add second instance of Oracle 9i on same machine. What should I do? Please recommend me too.
Note OS: Windows Server 2003 Standard Edition
Oracle: Oracle 9.2.0.1.0
Best regards,
Choosak B.

First, are you sure you want to have separate ports? Normally, you would just run a single listener and register all the databases on the system with that listener.
If you do want to run multiple listeners, the listener.ora file specifies the port to listen on.

Running multiple instances on same machine

I need to run multiple instances of BEA WLS on a unix machine. I need 4 separate instances (dev and test for two different departments) on one machine and two production instances on another machine. What is the best way to go about separating these (ex. an account or directory structure for each)?
Thanks,
Roger ---|-

Dev/Test:
Give each one its own domain name - i.e. a separate directory under config. This
works well.
Production:
Do the same, but to keep licensing costs down, I'd be inclined to run everything
on a single instance.

How to get rid of multiple instance of same machine

Hi, I have an issue with my MacPro as I have multiple instance of the same computer. Let me explain : My machine appears as MacPro. but sometime it connect as MacPro (2), or MacPro (3) and so on... I now have MacPro (11). This happens when I get problem with my network... it reconnect the machine with a new name... Big deal you'll tell me... let it be that way and carry on... But Here is where I have a problem : Third party application such as SpeedDownload see all those Instance as Multiples machines and now it won't open because it tells me that I only have a licence for one computer and that the software is installed on multiple computers as MacPro, MacPro (2), MacPro (3), ... and MacPro (11).
Is there a way I could get rid of all the other "Instances" and only keep on machine which would be MacPro?
Thank You,

Can I install two independent instances of Thunderbird on the same machine?

It is required to install two instances of Thunderbird on the same machine, each with its own account(s), Profiles folder(s) and sign-on password, so that each of two users can securely use Thunderbird at different times..
How can this be achieved?
Thanks,
NMB1

The simplest method is to install Thunderdird normally from an admin account. The two or more users then use ordinary none admin accounts. Thunderbird will be available to each user and each OS account has a separate Thunderbird profile, so each user has effectively totally separate Thunderird accounts and passwords.

If are only getting your site hosted, then, normally, the host would handle clustering (to your sepcifications, of course, but it is normally the hosts responsibility).
If i need to implement clustering and load balancing for tomcat server then do we need to go for 2 different servers for production environment?
Yes, you would need two, or more, servers.
Also please guide me on how to implement clustering and load balancing for tomcat server by running 2 instances on 2 different machine? I'm a newbie to it..
It should have no (or at least minimal) impact on the code (as long as you are using beans, sessions, and the other components properly). It is handled by the web container (by the tomcat in this case). The tomcat documentation should show how to set it up (if it supports it all, I don't know, we don't have Tomcat at work, and at home I use only a single).

Multiple instances of OC4J on the same machine

Is there a way to cofigure OC4J to have a few processes on the same machine, all listening to the same ports?
My purpose is to develope and deploy a few applications on the same machine, and each application should has its own process, so if onw fails or restarts, it will not effect the other applications and the other programmers.
I don't want to make each application to be bounded to differnt port.
is it possible ?

Two instances of oc4j cannot listen to the same port...you will
get an error.
To do this, you will need to cluster oc4j. This is fairly easy,
but you app needs to be "clusterable". All classes need to be
serializable which are used by your servlets. The
<distributable /> tag needs to be in your web.xml file. No
stateful session beans can be used. (sorry, but oc4j doens't yet
support clustering with sfsb's).
The second step is that your default-web-site.xml or *-web-
site.xml file should be set up for clustering. Do this by
creating a cluster-island attribute in your web-site tag. Also
change the port from 8000 to something like 8080 or 8090 or
something else. It should look like this:
<web-site host="192.168.1.101" port="8080" display-name="some-
name" cluster-island="1">
<default-web-app application="someapp" name="someappname" />
<frontend host="192.168.1.101" port="8000" />
<access-log path="../log/some-web-access.log" />
</web-site>
Your server.xml and application.xml will be the same as when you
don't cluster.
Make sure you have 3 different copies of your j2ee/home
directories...of course with different names....like home1 and
cluster.
Edit the rmi.xml and jms.xml files to change the port number
that the home1 oc4j will listen to. The jms port is usually 9127
by default, so use 9128. The rmi port is 23791, so change it to
21792. This will keep the rmi and jms servers from conflicting.
Make sure that the home1 config/default-web-site.xml uses a
different port than 8080, say 8090, but the cluster-island name
is still 1.
Open terminal windows for each instance of oc4j, and start them
in the normal way.... java -jar orion.jar
Open a terminal window for the j2ee/cluster, and issue this
command:
java -jar loadbalancer.jar -host 192.168.1.101 -port 8000
You should see that each of your oc4j instances are recognized.
There...that wasn't so bad, was it?

Communication between Two WebLogic instances on the same machine

Hi,
We're having a problem with communication between two copies of Weblogic on
the same machine. They are configured with seperate ports (regular and SSL).
Independantly, they run fine. I can access EJBs running on either of them.
The problem is that a bean in one of them has code which attempts to access
an EJB on the other one. The procude fails when trying to obtain the initial
context. This same code works if compilied independantly of WebLogic on the
same machine.
Are there any known issues regards communication between two running
instances of Weblogic on the same machine?
Thanks in advance,

Thanks for the prompt reply.
There is one IP address (internal address 10.227.1.34) one the machine. WLS1
is set up at ports 7001 and 5133. WLS2 is setup at ports 7004 and 7005.
When WLS1 attempts to obtain a context to WLS2 with the URL
t3://10.227.1.34:7004/ it pauses for a long period of time. Running truss
on the both WLS processes shows communication occuring between the two
followed by long periods of silence. Finally WLS2 spits out the error
ConnectionException[7001,7001,5133,5133,7001,7001] (paraphrased, I can get
the entire error if it would help).
After another long pause, WLS1 quits trying with the error 'Server
10.227.1.34:7004 not found' (again paraphrased).
Among the things we've tried:
* Changing the URL from the IP to 127.0.0.1
* Enabling/disabling SSL on either or both WLSs.
* Changing the server name in WLS2's copy of weblogic.properties from
'myserver' to 'myserver2' (previously they were both 'myserver')
* Upgrading WLS2 to 5.1.0sp5 (Tried upgrading WLS1, but was getting class
not found errors and quit because that WLS is being used by other people)
This is a Solaris server. WLS1 is running 5.1.0 and WLS2 is running 5.1.0sp5
Any suggestions would be appreciated.
Best,

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?

Can not get two instances to join same cluster even on same machine

On a RedHat Linux box, I have failed to get two instances of coherence to join the same cluster. I have managed to get the muticast test tool to show that packets are being sent and received. To do this, I had to:
java -cp bin/tangasol.jar -Djava.net.preferIPv4Stack=true com.tangosol.net.MulticastTest

However, I could not get the following to show that two instances are joining the same cluster... When I start to instances, both of them create a new cluster with only one member in each.
