Multiple instances of APEX on Single Box

Hi Everyone,
We are currently working on Oracle 1g APEX and looking for multiple APEX instances to be running on a single oracle server. Can it be possible? If it Is possible, then does it require any additional software installation or some kind of configuratin will be enough.
If anybody knows, please help.
regards,
Anuradha

You can have only one version of APEX per Oracle Instances.
What we do is have one database instance per APEX versions and only one HTTP server config.
Ex: SID : AX31 = APEX 3.1 and SID : AX32 = APEX 3.2
In the Dads.conf file , we setup a DAD for each like : /pls/AX31 and /pls/AX32

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 Instance of XI in one BOX ?

Hi All,
Is it possible to install two instances of XI (say DEV and QA environment) in one box.I understand for the abap stack we can use different system numbers for different environment.For the java stack,the port would then include the system number thus allowing multiple instances.
Has anyone tried this ,does it work?
Thanks in advance.
Regards,
Bikram

Hello,
I am not sure it could works because you can only connect one J2EE stack to one ABAP client.
In your case you need 1 J2EE Engine for each client -> So 2 J2EE Engine.
I am not sure you can install 2 JAVA Addin for one ABAP Stack !!??
Good luck
If you try it could post the result ?
Best regards,
Chris

Can one installation of SSIS be shared by multiple instances on the same physical box?

Hello everyone,
I hope I'm posting this question on the correct forum.
We are short on money this year and we decided to purchase one physical system to represent Development and QA.
I am designing an architecture around my systems where I would have a two SQL Server Instances (2014, Enterprise Ed), one for each environment:
DVSV-ODS01\DEV
DVSV-ODS01\QA
The only possible problem is SSIS, which I cannot have multiple installations of SSIS on the same box.
Is it possible to have the SSIS service serving the two SQL Server instances installed on the same physical box?
Thanks for your help.

Not on the same physical box, but you can go with running say the QA environment on a Virtual Machine.
E.g. the very free VirtualBox should do it. And then you can install two SSIS instances.
You can even access them simultaneously this way.

DG4MSQL: Multiple instances not working (only single instance)?

Hi I've been successfully using DG4MSQL for months to extract data from a local SQL Server 2005 instance to our 10g Ent 10.2.0.3 instance.
Today I was asked to add two more SQL server DB links on separate servers running the same version of SQL Server. Using the directions here seemed pretty straight forward, but I still can't get my two new SIDs (defined in the same listener) to respond. Every query over one of my new database links yields the usual
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from VHAV10PCSSQL
and my listener log shows a captain obvious:
TNS-12505: TNS:listener does not currently know of SID given in connect descriptor
Does anyone have experience setting up multiple gateways with DG4MSQL and SQL Server? I think the instructions may be missing something.
listener.ora:
SID_LIST_dg4msql =
(SID_LIST=
(SID_DESC=
(SID_NAME=dg4msql)
(ORACLE_HOME=/export/app/oracle-ee/product/dg4msql)

(PROGRAM=dg4msql)
dg4msql =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1522))
initX.ora:

tnsnames.ora:
serverx =

(CONNECT_DATA=(SID=serverx))

)

Hi thanks for the reply.
Yes I did restart the listener using an /etc/init.d/oracle_dg4msql script I created when I established the original instance. Interestingly, the output mentions only the one dg4msql instance with one service. It's like my listener.ora isn't even being used or the oracle_home isn't set correctly... D'oh!! Thanks for making me take a closer look. The correct listener.ora is not +/export/app/oracle-ee/product/dg4msql/dg4msql/admin/listener.ora+, it's +/export/app/oracle-ee/product/dg4msql/network/admin/listener.ora+. Yet another headache averted. Talk about annoyance! I'll put a big fat README reminder in that faux config folder. Thank you again.

AIA support for multiple brands implemented in multiple instances of Siebel

Good Day!
I would like to ask whether AIA has the capability to support multiple brands in terms of multiple instances of Siebel and BRM.
I have a client wherein they have a scenario of:
1.) To launch 4 different brands which contain multiple services and it has been decided that anything that holds customer specific data should be all in a separate instance (which would cover SIEBEL, BRM etc.)
2.) It is also a plan to have systems which only contain transactional data (mainly transient information) to have a central deployment platform (This would typically include OSM and AIA)
I've heard that this is possible with AIA but with heavy customization is required to be done. In case for customization, are there any white paper / documentation which talks about this?
So to summarize, here are the key questions:
-- Support of AIA to integrate multiple instances of Siebel, multiple instances of OBRM and single instance of OSM
-- Does AIA PIPS (mainly O2C, AABC) support data models (account, subscription, etc.,) of different services like 2G, 3G, LTE and Enterprise
-- Does AIA support more than 2 level hierarchies
-- Does AIA support charge redirection within the hierarchy
-- Does AIA PIPS support different MACD scenarios like suspend, resume, account movement within & across hierarchies especially for Enterprise Services?

Jeff

First off - Have no knowledge of ERPi - Just googled it.
If its any help, we have multiple instances of EBS on the same box, we have seperate DWH (and ODI Work / Master Repos) environments aligned to these instances. An ODI Agent can only communicate with one ODI Work repository, hence we have Multiple Agents so we can use the EBIZ -> DWH pairs simultaneasouly.
Maybe someone will come along and tell us how it could work differently, until then - its works for us!

Adobe Reader 9 - multiple instances performance issue

Dear all, I am having some performance issues regarding adobe reader, but only when running multiple instances. Opening a single, relatively small pdf ( 418kb ) works perfect, but adding to the list of open flies another very small file ( 102kb ), the cpu usage jumps to cca. 53% mouse movements become jumpy and the cooling fan goes nuts. Nothing helps until the second file I've opened is closed. Closing only the first instance doesn't help at all.
This happens with any two files I've tried. Large, small, graphics or not. Hardware is not the issue.
Any ideas?
Kind regards,
Vince

This second file: is it one you made? Or does it happen with any
second file?
If it isn't your file, does the problem stop if you turn off
JavaScript?

Multiple instances of the same APEX application under SSO

Currently we have several applications that are authenticated through Oracle SSO. The apps are authenticating correctly, but I can't be in multiple instances of the same application without having to re-validate through SSO when I move between instances.
Scenario: I'm successfully signed into my "parent" application, app_id 1 through SSO. I click a custom link that opens the "child" application (app_id 2) to view widget "A". When the page is launched I see the usual "Redirecting to the Login Server for authentication" message (verifying that I'm signed in through SSO) and then it succeeds and takes me into app 2, displaying widget A. I click the next link to launch another instance of app 2 with a different APEX session id for viewing widget "B". This also passes through SSO and redirects me into app 2, displaying widget B as expected. But now if I go back to navigate anywhere on widget A in my first instance, it has to go back through the "Redirecting to Login Server." This now means the widget A window is valid, but the widget B window will have to redirect next time I use it (back & forth & so on...)
So my question I suppose is: Is it possible/good practice to allow a single user to open multiple separate instances of the same APEX application using different APEX session_ids viewing different data under Oracle Enterprise SSO?
Guesstimation: It seems like there must be a switch somewhere in SSO that says "allow multiple application instances yes/no"...but my problem may be APEX itself, or how SSO is tied into APEX... Sorry for the super-generic example, I'm not exactly sure where I should be looking to resolve this, and the closest similar problem I found on the forums was here: login to application twice in two seperate IE windows clears other login

reset your dock preferences. delete the file homedirectory/library/preferences/com.apple.dock.plist and log out/in. your dock, spaces and exposé will be reset to the defaults. see if the problem goes away.

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

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 on single oracle home

Hi,
If i have multiple instances in a single oracle home
How can i know which instance is running (up)

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 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.

Can someone please tell me what is going wrong here?

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 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.

[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.

Multiple DNS Domain support in Single instance of Portal

Can BEA portal support multiple DNS domains in a single instance of BEA Portal.
For example can I setup portal to respond as bothe www.xxx.com and www.yyy.com
and keep those urls as trhough the entire portal?

Hi,
thanks for your quick response. You mean we should run only one copy of the package I mentioned and seperate the plants and machines by logic implemented in the package? Well, I think this is critical in case of deploying a new version, since all machines at all sites won't have the system available at the same time. At the moment we do not have things in the system that are needed to go on with production, but we have planned to implement some things that will be indispensable and in this stage we need a clear seperation of the plants to minimize the risk of a simultaneous stand at all plants.
Thanks for your suggestion and best regards,
Matthias
