Which is better a new schema or adding tables in the existing schema

Hi All,
We have a new requirement from the client asking us to include a few new functionalities(pages--- all together a new application has to be embedded into our application) in our application. By adding these new functionalities, the number of hits to our application can be doubled.
As per the above requirement, I would like to know that whether to create a new schema or to create some new tables in the existing database for the new functionalities.
By what way, can I handle the number of requests in a better way? by creating the new schema or by creating the new tables for the new functionalities.
Also I would like like to know what kind of factors will differ between creating a new schema or creating new tables for the new functionalities in the existing schema.
FYI... We are using Cold Fusion as front-end and Oracle 9i for back-end

I agree with VD in that it all depends on how closely the new features ties into your existing application structure.
The second major factor to consider is since you mention "for client" is if your application has more than one client and if you will be rolliong this feature into the application for all clients. If you have multiple clients but only this one gets this feature then it may make more sense to use a second schema, but it really depends on how easy to identify and separate this feature's objects for the purpose of maintaining it through future upgrades is going to be.

edison,
I run without a Virus Smasher Program. If I am going to download something I run Housecall. Also I do not use Outlook or Outlook Express for email so I do not get those types of attacks.
You could try Housecall here:
Trend Micro's free online virus scanner
This thing is a browser plugin. Does not run unless you are on their site. It is Free. It does not take up any recourses. It is Free. It is always up to date. It is Free. It never expires. It is Free. You never need to register to use it. Oh, and did I mention it is FREE!!! :D
Take Care,

Create a new message in Visual studio of the specified schema

Hi,
i need to create a message from the existing schema with my own values so let me know how can i create message from that schema in the visual studio
Regards,
Gyan

"create a message from the existing schema with my own values" at runtime this can be done using Message-assignment not the Transform shape as in the
map you generally transform the data from one schema to another (off course you can set default values in the map), but Map are to map from one schema to another not for creating a message with own values.
In Message-assignment, you can as suggested assign your values to the schema as shown. But Message-assignment shape has restrictions when you it comes to complex message
assignment.
Other option using Message-assignment is to call a C# helper where in the helper construct a message based on the schema and return the constructed message in the C# helper.
For this create a typed class based on your schema using XSD.exe. And construct this typed class in C# helper and return the message back.

How can i import tables from a different schema into the existing relational model... to add these tables in the existing model? plss help

how can i import tables from a different schema into the existing relational model... to add these tables in the existing relational/logical model? plss help
note; I already have the relational/logical model ready from one schema... and I need to add few more tables to this relational/logical model
can I import the same way as I did previously??
but even if I do the same how can I add it in the model?? as the logical model has already been engineered..
please help ...
thanks

Hi,
Before you start, you should probably take a backup copy of your design (the .dmd file and associated folder), in case the update does not work out as you had hoped.
You need to use Import > Data Dictionary again, to start the Data Dictionary Import Wizard.
In step 1 use a suitable database connection that can access the relevant table definitions.
In step 2 select the schema (or schemas) to import. The "Import to" field in the lower left part of the main panel allows you to select which existing Relational Model to import into (or to specify that a new Relational Model is to be created).
In step 3 select the tables to import. (Note that if there are an Foreign Key constraints between the new tables and any tables you had previously imported, you should also include the previous tables, otherwise the Foreign Key constraints will not be imported.)
After the import itself has completed, the "Compare Models" dialog is displayed. This shows the differences between the model being imported and the previous state of the model, and allows you to select which changes are to be applied.
Just selecting the Merge button should apply all the additions and changes in the new import.
Having updated your Relational Model, you can then update your Logical Model. To do this you repeat the "Engineer to Logical Model". This displays the "Engineer to Logical Model" dialog, which shows the changes which will be applied to the Logical Model, and allows you to select which changes are to be applied.
Just selecting the Engineer button should apply all the additions and changes.
I hope this helps you achieve what you want.

I deleted the profile and firefox4 and then downloaded firefox4 again. But when i click firefox it says Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process,or restart your system.HELP!

somehow i couldn't get rid of one website called www.searchqu.com/405 set as my homepage... I tried all solutions given to change the homepage but whenever i restarted firefox that homepage used to come automatically.. So, I deleted the profile (even from recycle bin!!) and deleted the firefox and downloaded it again hoping to get my problems fixed (which didn't happen!) because i'm getting dialog box saying- Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

You don't say which operating system you have installed?
Assuming it's Windows, right click a blank part of the Windows Taskbar and go to Task Manager. Then click the ''Processes ''tab, find '''firefox.exe''' and then right click it and choose '''End Process'''.

Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.

Issue in adding Space to the existing Virtual Machine from added repository

Hi,
I'm facing issue in adding Space to the existing Virtual Machine (Guest OS) from added repository.
Environment details :
VM Server : /OVS => 130GB
/OVS/935970F2CC2D4B4391701397517F1001/ => 512 GB
Things I have done :
•     I created a VM (Guest OS) in the VM Server with 120 GB
•     After creating the VM (Guest OS) , When I tried adding a VIRTUAL DISK of size 150 GB , I got an error “Maximum available Disk space is only 10GB”.
My query :
•     Will I be able to add space to Existing VM from the added Repository ( /OVS/935970F2CC2D4B4391701397517F1001/ ) , whose system.img is stored in path /OVS/running_pool/34_rhel/ .
Kindly help me out in this.
Thanks in advance.

Hi all,
I checked with Oracle on the above and got the info currently , the we can utilise only the space available in the existing repo and cannot extend to additional repo.
Work around is : Clone it to the other repo , or Use Symbolic link .
Thanks,

Firefox is OPEN and working fine, but when I click a link in Thunderbird I get 'Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.'

If I click a link on my desktop or in any other program (while Firefox is open and running), I get this message: "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." There's about a billion links for this if you Google it, but they all say that Firefox wasn't shut down properly. (OK, maybe not ALL of them, but if the needle is in that haystack, I haven't yet found it.) That's not the issue in my case since I haven't shut FF down at all.

Doesn't start when starting as administrator. Error Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

Update firefox, it asked me to update flash, I tried to update flash but it said I had to close firefox. A box came up and said the Flash install would continue when I closed firefox. I closed all firefox windows and no update of flash occurred. I tried relaunching firefox but got the "Doesn't start when starting as administrator. Error Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." message. I rebooted the system, no improvement. I tried to run firefox as administrator and got the same message. Either I find a fix or I won't be able to use firefox and will have to go back to ie.

Download a fresh Firefox copy and save the file to the desktop.
*Firefox 12.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Sorry I am a PC user but have you seen
* [[Firefox is already running but is not responding]]
Firefox will be hanging for some reason. The quick solutions to kill the process and try again. The next step is to try to see if it will start and exit normally a couple of times, if so the problem is solved. If not the reason needs further investigation.
See [[firefox hangs]]
An immediate likely culprit after repeated problems are the duplicate session restore files, as discussed in the above KB article.
