Multiple Instances of NetWeaver in a single installation (binary)

Hi,
My product has several versions. In WebLogic I have one installation and have created multiple instances each for each of the version. Can I do the same thing in NetWeaver? I am looking to see if I can create multiple instances of NetWeaver with a single binary installation by creating more directories/configuration files. Please let me know if this is possible and if so how it needs to be done. I am using NetWeaver's Java engine only.
Thanks and regards,
Raghu

Hi Raghu
In Netweaver also u can have serveral intances.There are two options:
1.Create seperate standalone instances.Here each instance will be a unique identity indepent to each other.You will have different SID(System identification number for each)
2.Create a centrel instances and u can have several dialog instances in the same machine.Here the SID will be one but as required you will have a seperate directory under that centrel instance for each diaolog instances.

Multiple Instances of OEDQ on a single server

Hi,
I am running a Linux Machine (Linux 2.6.18-308.1.1.0.1.el5), on which I have the latest version of Oracle 11g release 2 installed.
I have an instance of oracle Enterprise Data Quality tool running on an apache-tomcat-7 server. Port 8080
Now I have a requirement of Installing another instance of OEDQ on the same server, but a different APACHE_HOME directory and a different Port Number (8081).
So the question is, Can we install multiple instances of OEDQ on a single server?
If so, what are the prerequisites to be maintained.
I did my bit of tries, but ended up having issues with some java errors.
I have posted the error message below.
SEVERE: Context initialization failed
*org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'casemanager' defined in class path resource [conf/casemanagement.xml]: Cannot resolve reference to bean 'casedao' while setting bean property 'caseDAO';*

Hi,
Multiple instances of EDQ on a single server is technically possible provided the installer takes care to avoid port conflicts. It is not the case that there is a single port used by an EDQ server, for example.
For various reasons, it is not officially supported; attempting to diagnose issues on custom installations on Tomcat is especially difficult and we do not provide documentation on this. In general, the requirement usually comes up for Dev/Test instances (as there is no performance advantage of using multiple instances on a single server), where we would recommend the use of virtualization where this is a requirement.

Mike

Multiple instances of 9iAS in a single server

Hi,
Is it possible to have multiple instances of the 9iAS in the same machine.
I have managed to install two different instances of the infrastructure on the same machine with different homes. But while trying to install the second instance of the portal and wireless the installer selects the earlier instance of the infrastrucure (SSO and Meta repository). Is there anyway around this?
Thanks
Vinodh R.

I installed infrastructure in one machine and trying to install ias in other machine using infra on the first one. but iam getting one typical error again and again.
i.e when during the installation of ias we have enter the values of existing sso and ias-admin pwd...i entered the infra sso host name and also ias admin pwd. but it says..
'return value from sso running function is INVALID'. I want to install ias on second machine so that resources are not wasted on the first host. also i am getting wwc-41490 error when trying to login the sso page of infrastructure host. why is this. Kindly help me as portal config is very imp for me.

Issue with multiple instances of OC4J and one JDK installation

Hi,
I've successfully installed two instances of OC4J 10g (10.1.3.0.0) on a single server and am able to run with two differently named JDK 5.0 installs.
However, I've not been able to concurrently run both instances with a single JDK. The 2nd OC4J instance starts, but then stops immediately with a JVM termination.
Does anyone have an idea of the cause and a possible solution to the problem, as the current arrangement adds a level of complexity to upgrades that I'd like to remove?
Thanks,
Malcolm White

I run two OC4J 10.1.3.1 instances in parallel without any problem. Both instances use the same JDK and run without any problems. Seems you have some problems in you configuration.
Best,
Manfred

Installing Multiple instances of Essbase on a single machine

Dear gurus,
I have done the vanilla installation of Hyperion Suit of Products (11.1.2.2) on my VM machine (windows 2008 SP1, Its a Virtual Machine) ( I installed Foundation, EAS and just Essbase)
My First Essbase instance is running on default port 1423, and I tried to configure the second instance of Essbase using port 1424 and all donfiguration went successful. I can see the 2nd service of essbase up and running at services.msc
I followed the steps mentioned at:
http://docs.oracle.com/cd/E17236_01/epm.1112/epm_install_11121/frameset.htm?essbaseAgentPortPanel.html
My 1st instance is installed at: D:\Oracle\Middleware\user_projects\epmsystem1
My 2nd instance is installed at: D:\Oracle\Middleware\user_projects\epmsystem2
Now the problem is that, I am able to Add and Connect to 1st instance of Essbase (SERVERNAME:1423) using the admin account in EAS,
but when I try to add the 2nd Instance of Essbase as SERVERNAME:1424 using admin account , It throws following error:
Error on the EAS console:

Validating Essbase Server connection to SERVERNAME
Error: Cannot sign on as user already signed on.
Recommended Action: Check Essbase Server is started.
Can you please guide me what needs to be done to access this 2nd instance.
1) Do I need to have a separeate ADMIN user creation for this 2nd essbase instance? if Yes, then HOW?
2) Can I just copy the essbase.sec of 1st instance to 2nd instance?
Can You please point me to a some reference to have multiple independent instances of Essbase on same machine?
I sincerely thanks for your time to this request.
Warm Regards,
Amit

Super John,
Sincere thanks for your quick response As Suggested ,
I just followed the following steps and it worked
1) Run the "Stop server" (a shortcut on the desktop) to STOP the services
2) Run the D:\Oracle\Middleware\user_projects\epmsystem2\bin\stopEssbase.bat   to STOP the 2nd instance
3) Run the D:\Oracle\Middleware\user_projects\epmsystem1\bin\stopEssbase.bat   to STOP the 1st instance
4) For 2nd instance rename the Essbase.log and essbase.sec file to some dummy names e.g. like Essbase_old.log and essbase_old.sec
5) Now Run the "Start Server" (desktop shortcut)
6) Run the D:\Oracle\Middleware\user_projects\epmsystem2\bin\startEssbase.bat   to START the 2nd instance
7) Run the D:\Oracle\Middleware\user_projects\epmsystem1\bin\startEssbase.bat   to START the 1st instance
8) Add the 2nd and 1st instance to EAS
Warm Regards,
Amit Porwal

Multiple instances of app in a single JVM

Hi all,
I saw an article either on the web or in a magazine not too long ago about how to "detect" if the app is already running, and if so, it hands off the new instance to the already running JVM, which then creates a thread to run the Java app in. As it turns out, my app will be used in an ASP environment, through Citrix. We may have as many as 50 to 100 users running the same app, each with their own unique user ID, but all using the same one server to run it on. Each instance eats up 25MB of memory right now. So the question is if anybody knows of a URL or an app like this that can handle the process of running the same (or even different Java) apps in one JVM as separate threads, instead of requring several instances of the JVM to run? I know this article presented a fully working example, and I believe I know enough to do it but I wanted ot use the article as a reference to make sure it is done right. I know that each app basically would use the same one "launcher" program that would on first launch "listen" to a port, as well as send a message through the port to see if an existing launcher was running. If it does, it hands off the Java app to be run to the existing luancher application and shuts down the 2nd launching app. By using this method, the JVM eats up its normal memory, but each Java app only consumes its necessary memory as well and doesn't use up more JVM instance memory.
Thanks.

Anyone have any ideas on this one?

Log messages from multiple instances in single file.

Hi!
I have a requirement that i need to log messages from muliple instances of the same object in a file. The new file will be created every day. Likewise, multiple objects might have various instances each.
One class
->multiple instances
-> log message stored in single file.
Note :
I am using the Message driven bean. I need to log from the bean class. JDK 1.3
If u could help me out that would be great.

As long as they are all from the same OS program (a single Java VM), that's OK - you can use Log4j, and use a rotating file logger.
If you point two different virtual machine processes at the same file, one may have it open when the other is trying to rotate it, and your rotation may fail (at best) and/or you may lose the old log (the worst case).
If you need to collect log messages from multiple processes (or even multiple machines), use a syslog-based logger (Log4j has a SyslogAppender) or use Log4j's SocketAppender to write to a log4j-builtin log listener (SocketNode).

Multiple instances of VBAI

I know that we can now acquire from multiple cameras in VBAI (thanks!). However, I feel that doing so leads to very complex inspection sequences. It does not look like VBAI has fully embraced parallelism for things other than FTP transfer. What do I do if I have 5 GigE cameras that each must be triggered, and where it is possible that two could be triggered at the same time? Can I run multiple instances of VBAI on a single PC (hey, it's multicore)? I predict that the current answer is to just use LabVIEW, but VBAI is mostly LabVIEW.... right?
I would like to maintain only the simple, single-camera, inspections on the PC. Running multiple VBAI instances would allow me to dedicate an instance to each camera without worrying about what is going on wth the other 4 (or more).
No, I haven't tried to do this yet. Currently, I am out of town and away from my vision lab. I figured that if this is possible, it is worth mentioning to the public, and if it is not then it is worth mentioning to R&D. The system I am picturing would be a future version of a system we just completed where we had 4 NI Smart Cameras and one GigE camera. The question came up about what to do if all 5 cameras were GigE. Don't worry, we still love the SmartCams!

Solved!

FYI, feedback to Marketing / Product Development from an industrial user of several brands of vision systems...
I agree that it would be very useful to be able to run multiple instances of the VBAI application! Since each one would run in it's own process space, you could:
- Shut down individual inspections for program adjustments without affecting others that may be in the same program on different cameras.
- Make the programs simpler and easier to understand without as much branching logic.
- Make the NI software a better value, by allowing people to use 1 piece of generic hardware instead of multiple dedicated processors. (PC, CVS, SmartCamera, etc) This would make the NI software a more attractive choice for applications where we currently buy lower cost Banner, DVT, or Cognex units or if more power is needed-- an easier to maintain Keyence unit.
Currently IMO, because of the difficulties and expense involved with licensing, software version dependencies, and working with the NI hardware in general, I only consider NI where the additional functionality/flexibility is required. I have had good luck with PC-based applications of VBAI. If I could use an off-the-shelf industrial PC and run inspections in parallel-- making it easier to maintain and lowering the average cost per inspection, I probably would reconsider.
Thanks,
Mike

Db2 multiple instances in a single host

Hi,
os - windows 2008 db - db2 9.1 fp7
if i want to install 2 sap instances in a single machine in windows how to proceed?
1) I have read the documents where installation doc saying default db s/w path is /db2/db2sid/db2_software.is this the s/w path in windows? some where i read it saying default path is drive:/program files/IBM/sqllib.what is actually the difference?
2) and also read in the forum and also in the note 978555 and 930487,it says multiple instance is not possible in db2 ie we can have only 1 defalut copy of db2 so we cant have multiple instances with the different copies of db2(up to kernel version 7.0) .is this correct? for 1st instance it is /db2/db2sid1/db2_software and for 2nd instance it is /db2/db2sid2/db2_software right?so how we cant have 2 instances with 2 different db2 copies?
pls expain me.
Thanks

sqllib is only the links. The actual database is not this path.

Multiple instances on a single host is only supported as of 9.7 you would have to upgrade to that release.
You can technically have two instances as of 9.1 but as per the sap note s you have mentioned, this is not supported by SAP
For more information on 9.7 see:
http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/901b4314-9851-2c10-1c8f-b0ddd38d6e75

Hope this answers your query,

How to use/sync single data (file) across multiple instances of same application

Currently we have an application (a diagram editor), that have the ability to save and load (serialize) its state in a xml file.
Now we want this application to behave like Microsoft OneNote application. Where multiple users have the ability to access the same file.
Later we may also need to enhance with other things like, (1)what is changed and who changed it, (2)option to resolve conflicts if any.
I came to know about sync framework to resolve this. so far, i have not tried it.
All i want is,
Virtually single file should be edited by multiple instances of same application.
We need a dll (sync framework) that does following
It takes complete responsibility of file handling.
Using this dll, each instance of the application will notify their own changes.
Each instance of the application should have the ability to detect the changes that is recently made (when, who, what are the changes).
My question:
Will sync framework be suitable for this requirement?
If so, is there a demo application that represents this?
- Jegan

Seems like I have found the solution.
In the taskflow there is a property named data-control-scope and I set it to isolated instead of the default (shared) and this seemed to do the trick.
I can now have two instances of the same taskflow running with different ApplicationModules

Mark

Multiple instances operated on a single database on a single machine

Hi friends,
Can anybody tell that "Is it possible to operate multiple instances on a single database on a single machine"!?.
If so.., where this case is useful.
Please help on this doubt.
Thanks in advance.
Thanks
Srinivasa Rao

Hi,
I just asked whether it is possible or not. It is not much important. As you said, OPS will perform well if instances are on different machines. I agree on this. But I think we need to replicate the database on other machine also to run fast.Am I right?..If not, please correct me...
Thanks for valuable information.
I just re-read your post. When you say multiple instances on a single database, it sounds to me like you are asking about Oracle Parallel Server in 8i. I don't know why you would (or even if you could) have multiple instances on the same box. I don't think that would make sense since on of the benefits of OPS is to have more processing power by using multiple machines.

Multiple Instances on single oracle home

Hi,
If i have multiple instances in a single oracle home
How can i know which instance is running (up)
to which table i fire query to find instances status
how to start single instance out of multiple instances
Thanks,
Mustang

These questions show a certain lack of knowledge about Oracle - which immediately says that you also do not know what you are doing ito performance and scalability of a Oracle and that server platform by running multiple instances on it.
In most case, running multiple instances is the wrong thing to do. It degrades performance. It does not and cannot scale. It is an exception to the basic fundamentals of client-server. And not just for Oracle.
You need sound technical justification for running multiple instances on a server. What is yours?

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

[SOLVED] Multiple Instances of Word 2010; Possible to Force Single Instance?

Is it possible to either:
Control Word instancing so that its a single instace application; OR
Adjust the behavior so that if there's already an Word of word, new documents (no matter how they're launched) will open in the existing instance and NOT a new one?
I have a user who tends to open documents en masse/in bulk, highlighting 2-8 at a time and opening them (alternate-click > open OR once selected hitting [Enter]).
When they do this, multiple instances of Word are launched.
Very rarely is there an instance for each document, but its usually close. For example, if they opened 8 documents there might be 5-7 instances, with several instances showing 2 or more documents in View > Switch Windows.
Multiple instances of Word are a problem for this user because they because a heavy user of Ctrl+F6 / Ctrl+Shift+F6.
And when documents are spread out across multiple instances, this does not work: It does not allow them to cycle through all opened documents; It will only cycle through those that are within that particular instance of Word.
Is this by design?
Is this a change in the way earlier versions of Word behaved?
Is this an 'undocumented feature' [or worse]?
Can this behavior be controlled?

No idea; I'd call it a bug.
This behavior started with Word 2007 or 2010, earlier versions opened all documents within a single instance.
See 1.
No, unfortunately not.

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.
Ravi

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.
