Multiple instances of same view (Sun 1.2 JSF RI question)

Does the 1.2 RI support distinct backing bean and/or component state for multiple instances of the same view?
I've seen mention of a "window identifier" in the 1.2 spec and some RI patches (Issue 28 https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=28)
but the latest RI code no longer contains reference to this functionality. I've attempted to test this case, bringing up the same view in two frames (or two browsers - same session). But the state is still shared between the two views.
What configuration and/or calls need to be made to support multiple instances of the same view?

Using request scope would be a workaround.
I'm looking for view distinct state for the associated component tree for the session (i.e. managed bean state, whether its separate instances of the bean or copies of serialized state I don't care)
My views require conversational-like state handling that I don't want stored on the client.

Multiple instances of a view

I need to use multiple instances of a view within a window. I've been through the tutorial on component usage (with the 2 image views, etc.), but I need to have over 10 instances of the same view each with their own context values, etc., and setting up a component usage for each seems counter-productive.
Is there an easier way of having multiple view instances?
Thanks,
Cindy

Cindy,
In fact, this is "right way" -- encapsulate "view entry" functionality into one WD component, then create N usages to this component from some other (embedding) component. Btw, it is possible to create and assemble such usages dynamically.
The overhead of such component usages will not exceed (significantly) other startegies (say, dynamically create 10xN grid of controls in one view).

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

Can we have Multiple Instance on same Node in Oracle 10g RAC

Hi All,
I am planning to implement the RAC in Oracle 10g.Before that i have one doubt regarding RAC.
My question is "Can we create multiple Instance on Same node(Server) ?"
is it possible.
Any ideas or thoughts would be apperciable.
Thanks in Advance.
Anwar

This is where it is important to keep the separation between 'database' and 'instance'.
A database is the set of files that contains the data (and the redo, control files, etc). A database does nothing by itself, other than take up lots of disk space.
An instance is theCPU cycles (running software) and the memory to control the database.
In Oracle RAC, you can have as many instances controlling one database [at the same time] as you want (within reason). Each instance must be able to access the disk(s) that contains the database.
These multiple instances can be on the same computer (effectively taking up a lot of server memory and CPU for nothing) or they can be on separate computers.
If they are on separate computers, the disk subsystems must be able to be shared across computers - this is occasionally done using operating system clusterware and is the main reason why clusterware is required at all. (This is also the toughest part of the pre-requisites in setting up a RAC and is very vendor dependent unless you use ASM.)
These instances need a communication connection to coordinate their work (usually a separate network card for each computer) so they do not corrupt the disk when they are trying to access the same file, and possibly the same block, at the same time.
In a RAC configuration, instances can be added, started, running, stopped and removed independent of each other (allowing a lot of high availability) or can be started and stopped as a group.
Each instance gets it's own SID, which is in no way any different than a non-RAC SID. It's just the name of a service that can be invoked. The neat thing is that the SID
a) helps the DBA keep things straight by lettiung us talk about 'instance A' (the Oracle software to be running over on computer A) vs 'instance B' when starting, stopping and managing;
b) helps the application by providing targets that can be listed in the TNSNAMES.ORA [against one service alias], which is used by ORacle Networking to provide automated load balance or failover (instance/SID a is not available, I guess I'll try the next in the list)
Hope that helps the concept level a bit.

Running multiple instances from same oracle home

Hi Gurus,
I am preparing for OCA 11g examination. I had a question about running multiple instances from same oracle home. While reading the book I came across a statement about database control which says "If there are several database instances running off the same Oracle home, then each will have its own Database Control instance".
Now I assume that this statement implies multiple instances accessing the same physical database (which as per my knowledge can happen only in case of a RAC).
I am not able to understand how exactly can you have multiple database instances in a single oracle home. I have installed Oracle 11g on my computer whose oracle home is +"D:\oracle\product\10.2.0\db_1"+; now this directory houses all the binaries (executables and folders like admin,bin, etc) for the oracle instance that I have installed (the instance name is ocp1). Now if I am to install or create another Oracle Instance (say ocp2) in the same home, wont there be a conflict of binaries of the two instances in the same home ?
Basically,it makes sense if db_1 folder is further split into multiple folders, one for each instance (for example, one for ocp1 & one for ocp2); each of these folders will then contain the binary files, libraries,etc for its own instance; but, this is not the case, here db_1 houses all the binaries directly under it ...
The other question which stems from the statement I mentioned above is that if having multiple instances running from same oracle home accessing the same physical database, can this arrangement be called RAC at all; or does RAC dictate that you cannot have multiple instances that are accessing the same database have to be installed on physically separate machines and so you cannot have two RAC instances (accessing same physical database) installed on the same computer ??
I hope my questions are not too much confusing ... !!
Cheers,
Sudripta

Hello,
"If there are several database instances running off the same Oracle home, then each will have its own Database Control instance".This is true, and also means each instance will have its separate database (i.e. dbf files etc.) & separate DB Control. Usually in this case you create several instances on the same node.
Now I assume that this statement implies multiple instances accessing the same physical database (which as per my knowledge can happen only in case of a RAC).You are correct about RAC where several instances (usually running on separate nodes) access the RAC.
More info:
1 Oracle Home - 1 Database - 1 SID is possible.
1 Oracle Home - Many Databases - Many SID is possible.
1 Oracle HOme - 1 Database - Multiple SID is possible and this is called RAC.

How to open multiple instances of same form thru menu items

i'm not able to open another instance of the form.....if i want to open multiple instances of same form ...what should i do???

Hi Shenaz,
To open multiple instances of the same form you need to set a different FormUID to each form you open.
So lets say your FormType is MyFormXPTO. You need can set the FormUID as MyFormXPTO_1, MyFormXPTO_2, and so on.
If you need a code samples, take a look at this post.

Multiple instances of same component become non-editable

I have created a simple component for authors to add links. They enter anchor text, link destination, title attribute, via textfield. They set the target attribute via a dropdown list, xtype=selection. The issue we run into, is that if the author has entered multiple instances of the same component on a page, the dropdowns become non-editable after they are set the first time. They cannot be edited changed until the page edit view/content finder is closed and reopened.
Scenario:
1. User drag/drops component
2. User makes selection from dropdown xtype=selection
3. User drag/drops same component again to allowed parent
4. User make selection from dropdown xtype=selection in second instance of component
5. User can no longer change the selection in either instance of the component without closing and reopening edit view/content finder.
6. User closes and reopens edit view/content finder.
7. Again, both instances of the dropdown xtype=selection become non-editable after first selection of an option until the edit view/content finder is closed and reopened.
When there is only one instance of the component on the page, the drop downs/xtype=select remain editable at all times.
In addition to this particular scenario, I've had to work around some other issues of multiple instances of a component, where only one instance on a page works at all, the data gets crossed/jumbled between instances of the same component, etc.
My question is first, how might I solve for the scenario fully called out in this question? Secondly, is there some methodology to making multiple instances of the same component track themselves individually, work together on the same page, play nicely with each other?
Any assistance is appreciated.

Using request scope would be a workaround.

Multiple instance of same mac on network

Hello,
Running OS X Yosemite, I've noticed multiple instances of the same mac appearing on my home network. Has anyone else encountered this and know of a way to fix it? Currently, I have to try more than one instance before I find the "correct" icon to connect.

10.10.1, when I posted. Last night I installed 10.10.2. It got hung up on the "Restarting..." (w/App Store logo) screen for over 2 hrs, so I let it run overnight. It was still stuck in the morning so I just shut it down. After restarting, everything looks fine (cautiously optimistic)! There is only ONE instance on the network!! I read some tips in other forums and the simplest one I used, which wouldn't do more harm than good, was to turn off my air printer during the reboot. I am good for now and will repost if the problem returns. William Lloyd how long since you updated have you been multiple-instance-free?

How to create multiple instances within same AS

Ramesh,
I have a unique problem. I might have to create B2B instances for 4 owners. As in BPEL, I can have separate domains for the 4 clients in the same instance; what is the equivalent in B2B?
I have a limited number of CPUs and need to install the instances on the same box and hence trying to be creative yet secure here.
Could you please provide some pointers.
Thanks
Shamik

Hello Shamik,
Please elaborate your use case. Is this just caters to user management or to really have different domain like bpel for four different users. Please see, b2b do not have the notion of BPEL domain, you might have to install multiple instances of B2B pointing to the same MR.

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.

Running multiple instances of same servlet

I am trying to run multiple webapps off of the same weblogic5.1 instance.
          I have setup the webapps and they work individually, but I need one servlet
          to load at startup.
          I have only been able to do that by including it by name in
          weblogic.properties
          #webApp named
          weblogic.httpd.webApp.demand=d:/stat_forecast/
          #register servlet so it runs on startup
          weblogic.httpd.register.AppInitServlet=com.ai.servlets.AppInitServlet
          weblogic.httpd.initArgs.AppInitServlet=AppConfigFilename=d:/stat_forecast/pr
          operties/forecast.properties
          weblogic.system.startupClass.aiservlet=weblogic.servlet.utils.ServletStartup
          weblogic.system.startupArgs.aiservlet=servlet=AppInitServlet
          This works until I try to add another instance of AppInitServlet for a
          different webApp
          #webApp named
          weblogic.httpd.webApp.supply=d:/supply/
          #register servlet so it runs on startup
          weblogic.httpd.register.AppInitServletS=com.ai.servlets.AppInitServlet
          weblogic.httpd.initArgs.AppInitServletS=AppConfigFilename=d:/supply/supply.p
          roperties
          weblogic.system.startupClass.aiservletS=weblogic.servlet.utils.ServletStartu
          p
          weblogic.system.startupArgs.aiservletS=servlet=AppInitServletS
          The servlet does not run a second time.
          Is there a way to move the AppInitservlet to inside the webApp and maybe use
          the web.xml to start each one individually?
          Thank you for any insight

Replying to myself to try and clarify.
          We are trying to run 2 or more webapps, each webapp tryes to call the
          servlet AppInitServlet.
          The servlet will not allow more than one instance to be in a context.
          In tomcat the servlet works to give a separate instance for each app.

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,
Martin B.

"Updates" in Mac App Store contains multiple instances of same patch?

I started with a newly opened MacBook Air (mid-2013) with Mountain Lion. I used the Mac App Store to install Mavericks and the few subsequent OS patches. In "Updates", I see multiple instances of the same patch, listed a few times:
MacBook Air SMC Firmware Update v1.9 (3 times)
Digital Camera RAW Compatibility Update v4.09 (2 times)
MacBook Air EFI Firmware Update v2.7 (1 time)
iPhoto v9.5 (1 time)
I haven't noticed anything wrong with the system, but it's weird to see a patch "installed" multiple times? Anyone know why this is?
Thanks!

Yes, seen that little occurrence more than a few times, eventually it will vanish from what I've seen.
If you installed it fine, no worries.
techs are looking into this.
