What is the difference between Grid computing and Cluster ?
/sumit

You
can't easily switch a server from being a database
server into an application server when the load on
your system changes.
That's only because you didn't architect your grid that way. :P
(Mine doesn't do that either)
>
I guess people use the bits of the definitions that
support their marketing claims :)
Isn't that the truth!
Oracle marketing speaks of grid as a concept with their technologies enabling the grid. Other companys offer products that turn computers into (their defintion of) a grid - Sun's Grid Engine, Avaki's Grid, and Platform's LSF come to mind.
Gotta love the marketing folks; especially at Oracle. It seems to me that when a product doesn't succeed, they tend to rebrand and reintroduce.

What is the differences between Transparent,Pooled and Cluster tables?

Hello all,
What is Pool table?What is the differences between Transparent,Pooled and Cluster tables?
Regards!
Purna

Transparent table:
Tables can be defined independently of the database in the ABAP Dictionary. The fields of the table are defined together with their (database-independent) data types and lengths.
A table definition in the ABAP Dictionary has the following components:
Table fields: The field names and the data types of the fields contained in the table are defined here.
Foreign keys: The foreign keys define the relationships between this table and other tables.
Technical settings: The technical settings define how the table is created on the database.
Indexes: Indexes can be defined for the table to speed up data selection from the table.
There are three categories of database tables in the ABAP Dictionary.
A physical table definition is created in the database for the table definition stored in the ABAP Dictionary for transparent tables when the table is activated. The table definition is translated from the ABAP Dictionary to a definition of the particular database.
On the other hand, pooled tables and cluster tables are not created in the database. The data of these tables is stored in the corresponding table pool or table cluster. It is not necessary to create indexes and technical settings for pooled and cluster tables.
Pooled table
Pooled tables can be used to store control data (e.g. screen sequences, program parameters or temporary data). Several pooled tables can be combined to form a table pool. The table pool corresponds to a physical table on the database in which all the records of the allocated pooled tables are stored.
Cluster table
Cluster tables contain continuous text, for example, documentation. Several cluster tables can be combined to form a table cluster. Several logical lines of different tables are combined to form a physical record in this table type. This permits object-by-object storage or object-by-object access. In order to combine tables in clusters, at least parts of the keys must agree. Several cluster tables are stored in one corresponding table on the database.

What is the difference between GRID DISPLAY AND LIST DISPLAY

COULD U PLZ GIVE ME THE CLEAR DIFFERENCE.

hi,
1. For all practical purposes, they are the same.
2. Some differences:
a) from abap coding point of view,
alv list is done with Function modules,
alv gris can also be done with FM,
but can also be done using OO concepts.
b) Alv grid (using oo concept) requires
designing the screen layout .
Hence, in one screen, we can show more
then one alv grid
(we cannot show more than
one alv list on one screen)
c) ALV grid uses ActiveX controls
present on the Presentation Server.
Hence, it consumes More Memory
on the presentation server.
d) ALV LIST is Display Only.
Whereas
ALV Grid Can Be made EDITABLE for entry purpose.
e) In alv grid, these options are possible,
but not in alv list.
without horizontal lines
without vertical lines
without cell merging during sorts
display total lines above the entries
ALV LIST Can be coded using only FMs
ALV GRID Can be coded using FMs and object oriented concepts
ALV LIST Can be displayed hieraicharlly
ALV GRID cannot be displayed hierarichally
I hope it helps.

What's the difference between shut down and log out?

Hi,
I have a MacBook Air and will sell it.
I like to take out my name but don't know how.
What will happen if I Log Out (my name comes after that)?
What's the difference between Shut down and Log out?
Help please,
Thanks

Welcome to the Apple Support Communities
The shut down turns off the Mac and a log out closes your user and take your computer to the log in screen. To sell the Mac, you have to reinstall Mac OS X erasing the disk. Open  > About this Mac and copy Version

What's the difference between "Full Name" and "Account Name"

Just re-install a new OS X Lion. On the "Create Your Computer Account" screen, what's the difference between "Full Name" and "Account Name"?

Your computer name by default would be "John David Appleseed's Macbook Pro"
But you can always change that in System Preferences->Sharing
And yes, the first account you set up will be an administrator.

both r free but they are used in diffrent applications. sdk are used for simple apps that run on your computer while j2e (enterprise edition) are ment for large distributed computer systems that include servers and such. if you don't know the diffrence you probably wont need the the j2e, only the sdk.

What's the difference between "My Contacts" and "All Contacts"?

What's the difference between "My Contacts" and "All Contacts"?
I have no other account other then my iCloud account (from what I can tell), but "My Contacts" has a significantly smaller number of contacts then "All Contacts".
What's the difference?

Thanks for posting the screenshots, that's helpful. I didn't realize that you were looking at your groups.
"All Contacts" include (as the name implies) all of your contacts. Below that are any contact groups that you may have defined. These would normally be such things as "Work", "Personal", "Doctors", etc.; any groups that you find useful to define. These contain subsets of the "All Contacts" group.
At some point, perhaps inadvertently, you must have created a group called "My Contacts", or imported it to iCloud from your computer. At the time this may have contained all of your contacts and would have had the same number of contacts as the "All Contacts" group. Then over time you probably added 433 additional contacts that were never part of the original "My Contacts" group, resulting in an "All Contacts" group that contained 1465 contacts.
If you don't have any use for the "My Contacts" group, you can delete it by clicking on it on the left sidebar, click the gear icon on the lower left and choose Delete. If you're concerned about doing this, you can make a backup of this group first by selecting it on the left sidebar, clicking on a single contact within the group, pressing Control-A to select them all (they should all be highlighted), then clicking the gear icon and choosing Export vCard. This will create a .vcf file that can later be imported back to iCloud if you ever need to (by clicking the gear icon again and choosing Import vCard).

What's the difference between reguler KDE and KDEmod?

Hello all,
In two weeks I get my new laptop, which will be capable of running Arch and KDE ( as my current computer isn't, somehow it only runs Fedora w/ Gnome)
Since I really like Arch and already got it working on Virtualbox, I want to install it on my new laptop. I'd like to get it working with KDE, but I noticed Arch also has KDEmod. I already searched the forums but couldn't really find an answer to my question: What is the difference between regular KDE and KDEmod and which one is better for me to use?
Thanks in advance!

Allan, i forgive you for your poor paragraph construction and sorry for me being a bit peeved
However, i know you have read more from the IRC log than just that one sentence by me...
Allan wrote:
From the IRC log, I do not think that conclusion is too far off, especially if you are considering Arch-Stable as your base... So saying "plain wrong" seems... well... plain wrong. Especially given the irc log:
<funkyou> in one sentence: to do what we really want to do, we need a stable platform.
So why not showing the whole picture and clear this up:
<funkyou> ok, to start: i think at least some of you have noticed that arch linux is a fine platform for what we want to deliver, but there are some little "annoyances"
<funkyou> mainly:
<funkyou> -.so bumps every few weeks
<funkyou> -the general "freshness"
<funkyou> -a lot of manual interaction needed (sometimes)
<funkyou> everyone can see these problems when looking at the forums, _most_ of them are related to updates
<funkyou> in one sentence: to do what we really want to do, we need a stable platform.
Makes more sense now? Its not that Arch is too unstable, its just that we cant keep up will all the changes... And this is not Archs "fault" nor anyone elses fault, its just going too fast for us. Most annoying or severe bugs in our tools are there due to upstream updates. And the reasons are not really the .so bumps (which are mostly solved by a simple rebuild) but also constantly changing apis and stuff. This is not a big problem in KDE (they keep their apis clean), but a big one when it comes to other stuff like parted, to give an example. And this is our main problem, we need to constantly adapt our code to upstream changes.
This even resulted in a repo with modified or "frozen" Arch packages just to keep our liveCD going, and now we are looking for solutions for this problem, and "stable" snapshots seem to be one way... Oh, and if we would do this (there is nothing announced yet), we would do our own snapshot every X months because ArchStable seems to be a dead project. We also considered cooperating with the ArchServer guys, but their stuff is really made for servers, so even while their project is really nice its not really an option for us.
Well, we'll see what we will do during the next months, now we are still testing and evaluating some solutions... Oh, and people, please stop any "we dont need another ubuntu" complaints...

HT1463 what is the difference between intel inside and intel core

What is the difference between intel inside and intel core?

Those two terms are not directly related. "Intel Inside" is a marketing phrase that just means that the computer that displays that phrase in advertisements has an Intel CPU inside, as opposed to an AMD processor, for instance. That's all. Intel core is not precisely a phrase I've seen; but it would simply refer to the central processing area (the "Core") inside an Intel processor.
Hope this helps

What is the difference between Topic Keywords and Index File Keywords?

What is the difference between Topic Keywords and Index File Keywords? Any advantages to using one over the other? Do they appear differently in the generated index?
RH9.0.2.271
I'm using Webhelp

Hi there
When you create a RoboHelp project you end up with many different ancillary files that are used to store different bits of information. Many of these files bear the name you assigned to the project at the time you created it. The index file has the project name and it ends with a .HHK file extension. (HHK meaning HTML Help Keywords)
Generally, unless you change RoboHelp's settings, you add keywords to this file and associate topics to the keywords via the Index pod. At the time you compile a CHM or generate other types of output, the file is consulted and the index is built.
As I said earlier, the default is to add keywords to the Index file until you configure RoboHelp to add the keywords to the topics themselves. Once you change this, any keyword added will become a META tag in the topic code. If your keyword is BOFFO, the META tag would look like this:
<meta name="MS-HKWD" content="BOFFO" />
When the help is compiled or generated, the Index (.HHK) file is consulted as normal, but any topics containing keywords added in this manner are also added to the Index you end up with. From the appearance perspective, the end user woudn't know the difference or be able to tell. Heck, if all you ever did was interact with the Index pod, you, as an author wouldn't know either. Well, other than the fact that the icons appear differently.
Operationally, keywords added to the topics themselves may hold an advantage in that if you were to import these topics into other projects, the Index keywords would already be present.
Hopefully this helps... Rick

What is the difference between Video-out and mirroring?

What is the difference between Video-out and mirroring? I can't get iPhone 4 video to work on my TV screen
I have just bought an MD098ZM/A (Apple 30-pin Digital AV Adapter). I am struggling to get it to show a picture on my TV. I know I'm doing something right because the audio is coming out of my TV speakers but no picture on the TV screen.
I have used the same HDMI channel (on the TV side) with the same cable and my thunderbolt port (MacBook Air) without any trouble - and on the same app (BBC iPlayer download then full-screen mode).
Now I note that the packaging for the MD098ZM/A says video-out on iPhone 4 but mirroring only on iPhone 4S. I only have an iPhone 4 (not the 4S). Now if the lack of iPhone 4 support for mirroring means that I can't play video material out to my TV, then in what sense is there any video-out capability at all?
There is only safety and warranty paperwork in the Apple adapter packaging - no help information. And I haven't found further guidance online either.
I do note somewhere online that it suggests that basic non-mirroring video-out (for this adapter) only works with some external TV sets. Any way of finding out which? I'm using a Sanyo CE32LD90-B LCD TV if it helps.
So far not doing very well.

Now found these but have had to give up on this adapter!

What is the difference between jsp :include and server side include

what is the difference between jsp :include and server side include(request dispatcher include method)????
i understand that both request dispatcher include method and jsp:include take dynamic data,so when would one use request dispatcher include and when jsp:include.
Is the usage interchangeable?i believe jsp include is used only for jsp/html but include directive can be used to include servlets ,jsp and html....correct me if i m wrong and
do suggest if u hav ny other diff in this context...

The difference really is: in what format do you want your inclusions? If your environment has many Java developers and only a few designers that focus mainly on, say, Flash, that might push you more towards the server-side include() directive. Or, if you have a large set of pages that receive dynamic content that is displayed in a consistent fashion (such as a workflow header area on a page).
If, on the other hand, you have more web designers, there may be a greater desire to deal in markup rather than Java code. Java developers themselves might prefer to view markup (JSP) that more resembles the eventual output than something occuring in Java code.
Finally, there are considerations of tiering. While it is totally possible to (and I have previously) implement 'view classes' that render markup or generate layout templates, JSP's offer, IMO, a subtle, psychological advantage. By forcing a developer to work in a different format, markup versus Java source, the separation on view from controller and model becomes a bit easier. It is still possible to make mistakes, but if a developer at some point notices, "Wait, I'm in a JSP, should I be importing a java.sql class?", then the choice to use JSP includes has paid off in spades.

Any call made from the API will automatically be set to the “Session Timeout” period, no matter
what. Calls made from EWA (Excel Web Access) will get the “Short Session Timeout” period assigned to it initially.

What is the difference between document class and normal class

Hi,
Please let me know what is the difference between document class and normal class.
And I have no idea which class should call as document class or call as an object.
Thanks
-Actionscript Developer

the document class is invoked immediately when your swf opens. the document class must subclass the sprite or movieclip class.
all other classes are invoked explicitly with code and need not subclass any other class.
