One app , 2 database

I have a requirement to deploy the same webapplication in the same server and point to another database.
I have utility classes in my app that makes database connections from a predefined connection pool or datasource configured in the application server.
I could create a new datasource to point to the new database, but what is the best way to have the same application switch between datasources for different deployments
any thoughts?

depends on your high level requirement
If the requirement is to have two instances of the same application then going for two different deployments will be better.
If what you want is to have same application instance use two database then you should make the application switch the database when needed.

Sun One App Server - Oracle Database 10g

Hi to all:
I�m developing a web application that uses an Oracle 10g database and a I want to use Sun One Application Server 7, the problem that I have is when I have been deployed the war file into the server and acces to my application, specifically when I try to acces a JSP that extracts data from database, I don't see anything of the information that I need, that's not the problem, the problem is that in the server console appear a message indicating that an SQLException occour and the message is "No suitable driver".
I test my methods before deploy the war file and the connection and data extraction are correct, I don't know if the version of the JDBC driver for the connection to Oracle Database 10g is incompatible or if it's impossible to use Sun One App Server 7 with a connection with Oracle 10g.
I tried with other web servers like Tomcat 5.0 and Sun Application Server 9 and the connection it's perfect.
Could somebody give some ideas or orientation please?????, im student, all help will be appreciated, thanks!!!

Rahul,
Yes there is an Enterprise Edition in the works. It will address the load balancing and fail over needs for deployments. More details are available here: http://wwws.sun.com/software/products/appsrvr_ee/home_appsrvr_ee.html
We will also be releasing more information in the October and November.

This:

says that your network setup is not correct. You need to resolve that first.
As for Broker setup steps how about the doc or our Data Guard 11g Handbook?

Ipad, filing, folders, opening a document with more than one app...

Hi
I am wondering about iPad filing, documents and the future that iOS 5 and iCloud hold.
Am I right in thinking that there will still be no file/folder structure and that documents will be held individually by apps?
This creates two problems for me:
1) I need to access the same document (e.g. a pdf file) from more than one app. For example, say I need to use iAnnotate to mark it up and Sente to file it. However each app keeps their own copy of the document, so the annotated copy from iAnnotate is not the same copy as the one filed correctly in the Sente database.
2) How do I keep the files for a specific project together? Say I have source documents, word-processing documents, presentations, images etc all related to one project: how do I keep them all together? If we had tagging (as in openmeta or similar) I could tag them - works beautifully on the desktop but not available on the iPad. If we had folders I could at least group them in folders... What is is the iPad solution?
M

Here's how I address # 1:
I use DropBox as my central hub to keep documents accessible and synced between my iPad and my laptop. That means that I export, share, copy or print the document, with my changes, to DropBox from whatever application I'm using. For example, if I open a PDF in PDF Expert (the app I use for reading and annotating) I can "open" a copy in DropBox with my annotations. For Pages and other iWork files I use DropDAV which enables me to save to DropBox via WebDAV. For other apps like Safari that don't have DropBox integration, I use Save2PDF to "print" a PDF to the appropriate DropBox folder.
As to #2, two things come to mind. The first is that you can use the search function to find related files if you put your tag in the title or somewhere else searchable. The second is that I set up a file structure in DropBox on my laptop that meets my needs (and is also one way to begin to emulate a file structure on the iPad). For example, i keep my current course files, with their presentations, documents, and spreadsheets, in DropBox. But many of my projects have so many components and so many images, etc, I've become used to having components in different applications (Aperture, iTunes, etc) and I do rely on my laptop (and its external drives) for my central and final project management. For things in process, though, the iPad works very well.
ICloud may change all this. :-)

Is there a report showing all the DDL objects for one APP?

Hi,
Is there a report showing all the DDL objects for one APP?
I need to move an app to my workspace. The workspace I need to move it from has approx 20 applications in it, thus all the tables, procedures, etc are too many.
What way is the easiest?
I've looked at exporting the DDL and the app. and look to see what the app needs. But it has many pages.
Thank you, BillC

DB lookup problem with Sun One App. Server 7.0,MySQL3.x - Red hat linux 7.2

Hi Group,
I have deployed my project in sun one application server 7.0 installed in red hat linux 7.2 and database is mysql. Its working in fine in normal conditions. I could not able to get connection from datasource after I kept my server 10 hours ideal. Again its working fine once I restarted the server. Please give me any solution to prevent this.
The same project is working fine under all conditions in Sun one app server 7.0 installed in windows 2000 server without any look up probem. I Got this problem only in linux OS.
mysql datasource class com.mysql.jdbc.jdbc2.optional.MysqlDataSource
please find the below code..
Context ctx = new InitialContext();
Datasource testDS = (javax.sql.DataSource)ctx.lookup( "jdbc/testDS");
Connection con = testDs.getConnection();

My team solved the problem and I thought that we would share.
The version of Xalan that was packaged with the JRE, that is installed by the Sun One app server, was at least 2 versions out of date. Updating the Xalan package solves the issue and the WAR file now works.
Again, this appears to be only on the Linux version as the package deploys and works perfectly on the Windows version.

How can a file be accessed by more than one app?

Hi,
I am new to iOS4 and the whole iPhone, iPod technology. I am really a windows user.
How can a file be accessed by more than one app. In my case I want to transfer a midi file from my PC to my iPod Touch and be able to open it from a couple of Midi Players which I am evaluating - or does each Midi Player have to import the file seperately for its own use?
Thanks,
Sam

It seems to me that what you want is exactly a session bean will do. The EJB container is responsible to maintain a certain number instances (configurable) of your session bean and serve multiple clients at the same time. Session beans are not necessarily destroyed after serving a client. If you configure your ejb server to have a pool size of 2 to 100, then you will always have at least 2 instances (no more than 100 even there are a lot of client access) of this ejb ready to serve. The only thing not clear to me is that do you want to use only ONE instance of this bean or you don't care as long as multiple clients can access this bean's service? Since you mentioned that there is not a real database access, you can certainly use a Singleton but a 'regular' session bean with static fields should do it also if these fields will not be modified by clients.

Loading text from one app to another

If we are using text members and we want to transfer comments from one app to another.
our steps are as follows.
1) Export indicators in Essbase
2) LCM text members out of one app to import into the other.
3) load indicators in new app
4) load LCM file to new app.
The wrinkle is the following
App 2 already has the exact same member for text and there is already text in separate spots (no overlap - think 2 different versions). But what about the number system when we bring it back in.
Has anyone done this where you have to reallign the indicators in the relational database and essbase so that nothing gets crushed?
We are thinking of editing the files and create new numbers. Will that work?
This is version 11.1.2.2

Why Not One App for Mail, Address Book, and Cal?

I don't understand the logic of why Apple continues to keep all these applications seperated!
Why do I need iCal, Address Book, and Mail - three seperate applications that should really be under one. All three of these apps are connected to each other, so they should all be under the same umbella! Why waste the memory and processing power having all three open and just consolidate them all into one app like every other messaging client!
Can anybody explain to me why Apple continues to keep these items in seperate applications?

Personal preference but I prefer having three separate applications.
Name like every other email client besides Microsoft's Entourage and Outlook that include all three applications under one umbrella. Entourage and Outlook define a bloated application IMO.
Entourage stores ALL data in a single large database which I'm not a fan of. If a problem develops with a single database that stores all data, there is the potential for all data to be lost. For the Mail.app, Address Book and iCal to be combined, it would probably require the same. Each has its own data files and storage location now.
When using the Mail.app, there is no reason to keep the Address Book application launched and running unless you need to edit an existing contact. You can add an email address to the Address Book that is not already entered from a received or sent message or from the list of Previous Recipients in Mail.
When the Mail.app, Address Book and iCal are launched, they take up some real memory (obviously) but combined, not much more than Entourage. When Entourage is launched and not being used, it is ALWAYS in an Active Processes state along with the Entourage Database Daemon which is not the same with the Mail.app, Address Book and iCal.

How do i get my ipod touch to download more than one app at a time, can i make it toware i dont have to wait for one app to download before it starts downloading another,

my ipod will only download one app at a time and runs extremely slow. i was wondering if there is some way that i can make it download more than one app at a time and how can i make the app start downloading again after i have left my wi-fi zone and then went back in. im really confused.

Download everything on your computer in iTunes, then sync your iPod to iTunes.
You should be syncing (backing up) to iTunes and your photo app regurally, anyway.

Can you download more than one app at a time?

Basically, can I purchase two apps for OS X, both large downloads, and leave it overnight trusting both to be ready when I come back to the machine? Will they download one at a time, or concurrently?
Thanks

Only one app can be downloaded simultaneously. However, if you select to install both before going to bed, both should be downloaded and installed when you wake up, before when one app finishes installing, the other one will start being installed

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine until I deleted an app in error. When I downloaded it from iTunes, my account is no longer recognized by the app's host servers. Can I go back and re-sync one app from my old phone?

I upgraded from iPhone 3GS to iPhone 6. Everything converted fine. Yesterday I deleted an app in error. When I downloaded the software it from iTunes ( did this many times on the old 3GS), my account is no longer recognized by the app's host servers (Playtika), even though it did after the initial conversion. Can I go back and re-sync just one app from my old phone?

Try deleting what is called the iPod Photo Cache.
