X131e back cover FRUs - what's the difference between DEC or not?

I'd like to buy a replacement LCD cover kit for an x131e but the FRU part lists the following: 04W3863 LCD Cover Kit Black04W3864 LCD Cover Kit Red04W6853 LCD Cover Kit Yellow04Y1781 LCD Cover Kit DEC Red04Y1782 LCD Cover Kit DEC White04Y1783 LCD Cover Kit DEC BlackWhat's the difference between DEC or not DEC? I can't find any visual differences in the few websites that carry them.

The difference is TVSU stopped working and TVUR+TI still works.

What is the difference between Never and Not supported

What is the difference between Never and Not supported?
Also I want to know what are all the transaction attibutes are supported by MDB and why?

Never- If the bean is called in an existing trasaction an exception is thrown.
NotSupported - Methods always execute outside the transaction context. If a transaction is started when this method is called, this method is executed outside the transaction. The initial transaction is continued after the method exits.

what's the difference between the Icloud and Itunes when installing back up???

Backing up using iTunes stores your backup locally on your computer. Using iCloud stores your backup on Apple's servers. If you never backup your computer(bad idea), iCloud would be a better choice. Read more here:

What is the difference between exists and in

hi all
if i have these queries
1- select ename from emp where ename in ( select ename from emp where empno=10)
and
2- select ename from emp where exists ( select ename from emp where empno=10)
what is the difference between exists and in is that only when i use in i have to bring the field name or what.... i mean in a complex SQL queries is it will give the same answer
Thanks

You get two entirely different result sets that may be the same. Haah! What do I mean by that.
SQL> select table_name from user_tables;
TABLE_NAME
BAR
FOO
2 rows selected.
SQL> select table_name from user_tables where table_name in (select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
FOO
1 row selected.
SQL> select table_name from user_tables where exists(select table_name from user_tables where table_name = 'FOO');
TABLE_NAME
BAR
FOO
2 rows selected.So, why is this? the WHERE EXISTS means 'if the next is true', much like where 1=1 being always true and 1=2 being always false. In this case, where exists could be TRUE or FALSE, depending on the subquery.
WHERE EXISTS can be useful for something like testing if we have data, without actually having to return columns.
So, if you want to see if an employee exists you might say
SELECT 1 FROM DUAL WHERE EXISTS( select * from emp where empid = 10);
If there is a row in emp for empid=10, then you get back 1 from dual;
This is what I call an 'optimistic' lookup because the WHERE EXISTS ends as soon as there is a hit. It does not care how many - only that at least one exists. It is optimistic because it will continue processing the table lookup until either it hits or reaches the end of the table - for a non-indexed query.

What is the difference between Wine, Wineskin, Winery and Wine Bottler, and how do I get Wine to *ACTUALLY* work in Mountain Lion?

Ok, so this is my first post here and I am admittedly terrible at forums. Someone might say, "This was addressed in the ___________ thread by __________! Go read it!" --- that may be so but I've spent enough hours trying to google this problem into submission to no avail based on what is apparently working for others, so I would like a chance to get specific answers to specific questions that aren't from Mar 2011, etc.
So first of all, I'm confused by all the various Wine programs/apps/whatevers. I've seen Wine, Wineskin, Winery, Wine Bottler, and at this point I wouldn't be surprised if there are even more than that. What's the difference between all of these and how do they work with one another? What do I actually need to get windows programs working?
All of my google searches have led me to people giving out fish, but no one giving out fishing lessons. I'm not a pro at mac and windows and all that, but I'm a fairly bright individual who gets VERY frustrated, very quickly, when I don't understand the why and how of something I'm attempting.
I've also found "answers" where the person attempting to help starts off helpful enough, but degrades into the most archaic of techno-babble after about 5-6 sentences. On the other hand, I've watched tutorials on youtube where the poster decides to skip (apparently crucial) sections of the tutorial, and mutters such gems as: "... you might wanna have to run Wine first before you can do anything, cuz I think it has to configure it and set up a bunch of stuff"
O.o
A happy medium between techno-babble and the most basic of explanations would be ideal for me, and I'd imagine for others as well.
Here is a summarized history of my relationship with Wine:
Diablo II - I downloaded this awesome thing which ended up being... uh... I guess Diablo II in a Wineskin "wrapper". I'm not sure, all I know is that it's a D2 icon, and if I go to 'show package contents', it's got C drive, Program Files, et cetera inside of it. I double click it, it launches D2, and it works like a dream. <3
'Vanilla Install' - That's what I heard someone call it. It was the command/terminal style install using xquartz and xcode found at http://www.davidbaumgold.com/tutorials/wine-mac/. I followed every instruction to the letter, and got all the way to '$ sudo port install wine', at which point it started going smoothly, free from the possible error he described regarding the installation of xcode, and then just failed after I left the room to use the restroom and came back. Please don't ask me to repeat what the error was, because honestly, after reading more things on the interwebs, I'm confused as to why it's even necessary to go through all of that, so I'd rather not try that route again anyways, rendering the error message quite possibly irrelevant.
Wine + Wine Bottler - So I decided to try to seek out an easier method, as I know that one must exist that doesn't involve command lines. I found a video tutorial at http://www.youtube.com/watch?v=m0BBkISOcEA, and oh man would it be great if that method had actually worked. Again, I followed all instructions provided to procure my free fish, and at the point in the video where he declares that "xquarts or x11 will open" - it doesn't open. Nothing opens. I was trying to install Star Sonata, btw.
So here I am, thoroughly worn out, frustrated at all the random places Wine is installed on my mac now, and just want someone to explain it all, from top down, without getting toooooooo technical on me. I know that might be asking a lot...

## I know that the poster has already found a solution, but the following is a possible answer for others that have similar issues.
For Winebottler, just go to their website and download it. Run the program. Choose .wine as your prefix (best choice) or whatever suits you best. You'll need a functional X11. If you can't use the one that comes with your mac, download the latest one from the website.
If your issue is one with Winebottler's Wine not running correctly due to X11, then you have a pretty ugly problem, although a simple upgrade is the best solution (Upgrade XQuartz.app).
http://www.davidbaumgold.com/tutorials/wine-mac/#part-1
The above website is the easiest way to get REAL wine on your computer. First of all, Wineskin WInery, etc. are NOT WINE. They are 3rd party apps that may use Wine or may have originally part of Wine, but they are no longer up to date with Wine. WineBottler is currently up to date with the stable releases of Wine (but not the maintenence releases).
For the website tutorial and to run Wine on your mac without using a thrid party app, you will need to know a few things.
First, you will need to know basic control of the command line. That means, sudo (you must know the administrator password to your computer), and the forms of cd (change directory).
Second, you will need Xcode. Download 4.2 (stable) or whatever other versions you want, but beware: It is over 1 GB, and you will need time for it to work.
Third, you will need to get MacPorts and configure it. The tutorial should have this data.
When you download wine (use sudo port install wine-devel for the latest development release of wine), it will first download a lot of dependencies. This will take a while. After that, it will download wine itself.
After obtaining wine, to run a program, open the terminal.app window.
cd desktop/XYZ/ZYZ\ WRQ
The above will first enter the desktop, then folder XYZ, then folder ZYZ WRQ. From here,
wine th11e.exe
Or whatever executable you are trying to open. (Using Subterranean Animism as my example).
It should, in theory, run the program. Watch the terminal for errors. If there is an X11 problem, then it's not wine acting up. If the app crashes or has other issues, check the Wine Application Database to see if your app is compatible with wine.
If you have any further questions or other things, feel free to reply; I may or may not get back to you, but there's a good chance that someone will come in eventually. Otherwise, the Wine Wiki should have some information.

What is the difference between Constant Window, Variable Window,Main Window

hello all
what is the difference between 1) Constant Window
2) Variable Window
3) Main Window in SAP SCRIPT

Hi,
Window Types
When defining a form window, you must select a window type for the window.
You can choose between three types:
Constant Windows (CONST)
Variable Windows (VAR)
Main Windows (MAIN)
Constant Windows (CONST)
Starting with Release 4.0, the system internally processes windows of type CONST similar to windows of type VAR.
Therefore, if you create a new window, always use type VAR.
Variable Windows (VAR)
The contents of variable windows is processed again for each page, on which the window appears.
The system outputs only as much text as fits into the window. Text exceeding the window size is truncated;
the system does not trigger a page break. Unlike constant windows, the page windows declared as variable windows may have different sizes on different form pages.
As far as the processing of the window contents is concerned, the system currently treats constant and variable windows alike.
The only difference is that constant windows have the same size throughout the form.
Main Windows (MAIN)
Each form must have one window of type MAIN. Such a window is called the main window of the form.
For SAPscript forms, the main window has a central meaning:
It controls the page break.
It contains the text body that may cover several pages.
It allows to fix text elements at the upper and lower margins of the allocated page window (for example, for column headings).
As soon as a window of type MAIN is full, SAPscript automatically triggers a page break and continues to
output the remaining text in the main window of the subsequent page. Page windows of type MAIN have the same width throughout the form.
The SAPscript composer thus avoids reformatting of the text after each page break.
If a page does not have a main window, the system implicitly processes all other windows of the page and continues with the subsequent page.
This page must not call itself as subsequent page (recursive call), since this would produce an endless loop.
In such a case, SAPscript terminates the output after three subsequent pages.
For printing header lines or totals, the different output areas of the main window are of special importance.

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 are the differences between Cartweaver CF and PHP?

I am on my final step of finishing the webpage that I am building and saw Cartweaver for a shopping cart that is compatible with dreamweaver. But I looked into the site and hey didnt give an explanation between the CF and PHP version. So I would like to know the differences and which one would work best with Dreamweaver Cs6.

Hi Kendall,
As far as application differences, functionality wise, there is no difference. Both Cartweaver 4 CF and Cartweaver 4 PHP function and present themselves exactly the same. As far as implementation there are very subtle differences due the the way CF and PHP work, but they both are very close and use "includes" to place the Cartweaver functionality in your site penetration pages. The web based store admins work exactly the same for both. So you get the same results no matter which direction you go.
Now what is the difference between PHP and ColdFusion? That is a very important question as it will impact what platform you use from now on - for this site, and possably future sites you build so this is worth taking a little time to consider.
Which is best? Well this could lead to a discussion like which is best Mac or PC? There are evangelists and zealots on both sides. The real truth of the matter is both are good choices, you just need to decide which is best, for you. One poster said "what does your host support" - good point, but if you are new to working with dynamic web sites and are deciding what platform you want to go with there are more important factors to consider than what your current host supports. You can always select a different host.
The biggest difference between CF and PHP is they way they are written - PHP is script pasted, much like JavaScript, CFML is tag based much like html. Because of this CFML is often a little easier to learn because it's a bit easier to look at something and figure out what it's doing. So you may want to take a little time looking at this aspect.
Fact is though, with either one because Cartweaver does the vast majority of anything to do with code for you, learning the language is something you may not choose to do anyway. An advantage to PHP is that it has much wider support, so finding developers to help out, or hosts can easier with PHP. So if you don't have any desire to dig in and learn code as you go and only want to learn what's necessary to get your shopping cart site up, then the steps and learning curve are pretty much the same and PHP may be a good way to go. If this raises more questions than it answerers, let me know I'd be happy to discuss this more with you offline.
So, back to the basics - from a functionality point, they are both the same. You only need to choose which platform you think will work best for you and go from there.
I hope this helps. If you have any other questions at all, ask away.

HR deals with the INFOTYPES which are similar to Tables in General ABAP.
There are different ways of fetching data from these infotypes.
There are different areas in HR LIKE Personal Admn, Orgn Management, Benefits, Time amangement, Event Management, Payroll etc
Infotypes for these areas are different from one another area.
storing of records data in each type of area is different
LDBS like PNP are used in HR programing.
Instead of Select.. we use some ROUTINES and PROVIDE..ENDPROVIDE.. etc
and in the case of Pay roll we use Clusters and we Import and Export them for data fetching.
On the whole Normal ABAP is different from HR abap.

All custom developed infotypes stsrat with PA9000 onwards.
In payroll processing we use Clusters like PCL1,2,3 and 4.

Look at the below link
And finally,
Few notes are below:
InfoSets in the HR Application
You can use SAP Query in HR to report on HR data. Queries are maintained as described in Creating Queries. The special features of queries created for HR are described in Maintaining Queries in the Human Resources Application. The maintenance procedure for HR InfoSets differs from the described procedure inasmuch as HR data fields are grouped together in infotypes.
InfoSet management in SAP Query is also used for InfoSet Query. For further information, see Functions for Managing InfoSets.
If you want to create InfoSets for HR, you can use logical databases PNP, PNPCE, PAP, and PCH (see HR Logical Databases). The database you must use to create your InfoSet depends on the component in which the data you want to report on is stored.
The reports you can execute using InfoSets based on logical databases PNP (or PNPCE) or PCH are similar, but differ in that they can select different objects. The following table describes the connection between the logical database, and the infotypes you can include in an InfoSet. It also provides you with one or two examples of reports that you can execute using the appropriate InfoSets.
Logical database PNP/PNPCE* PCH PAP
Selection of Persons Objects from Personnel Planning Applicants
Infotypes that can be included in the InfoSet Infotypes for· Personnel Administration (0000-0999) · Time Management (2000-2999) · Payroll infotypes · Infotypes for Personnel Planning objects that can be related to persons If the object type is specified:· Infotypes for the object type · Infotypes for objects that can be related to the specified object typeIf the object type is not specified:· All infotypes · Infotypes for Recruitment (4000-4999)· Some infotypes for Personnel Administration (such as 0001 and 0002)
· Customer infotypes
Reporting examples · Selection of all persons who participated in a specific business event, output of prices for reserved business events · Selection of all persons assigned to a specific personnel area, output of qualifications held by these persons · Selection of all business events held in London in March, output of all persons who participated in these business events · Selection of all positions assigned to a specific organizational unit, output of all persons assigned to the positions · Selection of all applicants hired last year to work on special projects, output of addresses for the applicants selected
Logical database PNPCE (PNP Concurrent Employment) functions just like logical database PNP. The procedure for creating InfoSets is also the same. It only becomes significant if you work with Concurrent Employment.
Creating InfoSets
The maintenance procedure for HR InfoSets differs from the procedure described so far in this section inasmuch as HR data fields are grouped together in infotypes. To set up an InfoSet for the HR application, proceed as follows:
1. On the initial screen for maintaining InfoSets, enter a name for the InfoSet and choose Create.
2. On the next screen, enter a name for the InfoSet and select one of the HR logical databases in accordance with your reporting requirements.
Customer infotypes can be created on all HR logical databases. In each individual case, therefore, you must decide which database to select so that you can report on customer infotypes.
This screen enables you to enter an authorization group. All of the queries that are subsequently created using this InfoSet can only be executed by persons who have this authorization group.
3. Choose .
This takes you to the Infotype Selection for InfoSet screen. You now have the option of creating field groups and assigning fields as required for non-HR InfoSets. Field groups that correspond to infotypes and already contain fields, however, are always created for HR InfoSets. The field groups are displayed in an overview tree in the top right section of the screen.
The infotypes that you included in the InfoSet are displayed in an overview tree on the left of the screen. The infotype fields that are already included in field groups are displayed in a different color, and the corresponding field group ID is displayed.
In the standard system, a field group is created automatically for each infotype that you included in the InfoSet (a field group corresponds to an infotype).
In the standard system, each field group contains the infotype-specific fields. To ensure that working with the InfoSet is as easy as possible, you are advised to restrict your use of fields in each field group to those you really require. This means you should remove fields that are not required.
An infotype's fields must only be assigned to the pertinent field group. Make sure this assignment is correct. If the assignment is incorrect, the InfoSet could be rendered unusable.
When an InfoSet is created, the following fields are transferred automatically to the first field group:
§ Logical database PNPCE or PNP Personnel number
§ Logical database PAP Applicant number
§ Logical database PCH Object ID, plan version, and object type
6. Determine the fields that must be included in the field groups of your InfoSet. If you require further information, see Assigning Fields to a Field Group.
If you want, you can change the default sequence of field groups and fields as required using Drag&Drop.
7. To save the InfoSet, choose .
8. To generate the InfoSet, choose .
On the Change InfoSet (InfoSet name) screen, you can choose Edit ® Change infotype selection to add more infotypes to the InfoSet, or to remove infotypes from the InfoSet. Remember to regenerate the InfoSet afterwards.
This screen also enables you to update InfoSets if, for example, the system contains new additional fields for specific key values. To do so, choose InfoSet ® Additional functions ® Update additional HR fields.
9. Go back to the initial screen for InfoSet maintenance.
10. Choose User group assignment.
11. Select a user group, and save your entry.

Could any one tell me what is the difference between swfloader and module loader?

Hi All,
                      Could any one tell me what is the difference between SWFLoader and Module Loader in Flex3 in detail?

Hi,
ModuleLoader is a kind of strange API that is really just intended to look like SwfLoader for modules that contain a single visual component, and hides most of the module loading infrastructure, which is all about class factories.
What I mean by "only loaded once" is that if you have several places in the code that call the ModuleManager.getModule("url").load() call, it will only ever get loaded over the wire and interpreted once, subsequent "loads" will just re-dispatch pseudo-load events to the new client. In other words, the class factory is a singleton for a given url. Unloading is a totally different story. As you note, not everything is truly unloadable, because there may be lots of references to stuff in
the module that will keep it alive and un-GC'ed.
I suggest playing with the low-level API so that you understand the backing implementation, and this should help you understand the limits of ModuleLoader.
The main difference between modules and applications is that modules have lower overhead, and they only ever get loaded once, no matter how many times you load them. If you're using the ModuleLoader API, keep in mind that you're losing about half the functionality of the module system. I will assume that you are, because otherwise it would be obvious where to expose methods. You might want to play around with the lower level ModuleManager API just to get a hang of what's going on - ModuleLoader is a pretty thin veneer over the lower API.
                Basically, what you want to do is to have your module implement an interface, say IModuleWhatever.
Also try and refer to this link which was previously discussed in this forum..

What's the difference between Screen Sharing and Remote Management?

As the title asks. What is the difference between the two?
Because heres the thing. I set Screen Sharing on in Sharing. Then a few days later I will go back to the Sharing preferences and instead of Screen Sharing being checked. Remote Management is now checked, not Screen Sharing. What's the deal? Is that normal?
I was wondering if it was because I log into my iMac sometimes using my iPhone with that Mocha VNC program. Its the only program I use to remotely control my computer. Is that it?
Any help I can get is appreciated! Thanks!

Remote Management provides support for the additional functionality of Apple Remote Desktop as compared to a standard VNC setup. The options are otherwise identical.

What is the difference between closing your macbook & pressing apple-sleep?

What is the difference between closing your macbook & pressing apple-sleep? My friend aid that it is better to put your computer to sleep by pressing the apple then hitting sleep. I have been just closing it. Is there a difference? Also, is it better to shut your computer down every once and a while. It seems like it gets slow if I just have it sleep after a couple weeks. ALSO, after it has been on sleep every night for a while, my computer has trrouble turning off. I get the problem that says, the application finder has failed to quit try force quitting and try again

None.
There's no particular need to shut down the computer except when traveling or moving the computer.
Whatever other problems you've described have nothing to do with sleeping or shutdown. More likely you need to do some maintenance and/or check that you haven't installed incompatible third-party software.
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that presently AppleJack is not compatible with Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. Carbon Copy Cloner (Donationware)
6. SuperDuper! (Commercial)
7. Intego Personal Backup (Commercial)
8. Data Backup (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.

Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

What's the difference between these two backup systems?

When I bought my Macbook Pro I bought a Seagate external HD that used Bounceback Express as its backup application. But now my Mac defaults to Time Machine. What's the difference between the two applications? When I use Time Machine to back up my hard drive to the Seagate external, is it doing the same thing as Bounceback Express used to?

In analog terms, to explain YCbCr use the example of the COMPONENT output from your DVD player. It use 3 separate cables (Y = Luminance = Green Cable), (Y-B = Blue Color Diff = BLUE Cable) and (Y-R = Red Color Diff = RED Cable). In the analog world, RGB is actually RGBHV (5-wire) and is adaptable to 15-pin VGA with a simple passive adapter. Many people will mistakenly refer to Analog Component video as RGB, since the cables are Red, Green and Blue.
So, since all that mumbo jumbo means essentially the same, this appears to be the digital "equivalent" of what is known as Component Video in the Analog world... What I said about RGBHV does not apply to the 10-bit color, but thought I'd mention it anyway.

What is the difference between tkprof and explainplan

Hi,
what is the difference between tkprof and explainplan.

Execution Plans and the EXPLAIN PLAN Statement
Before the database server can execute a SQL statement, Oracle must first parse the statement and develop an execution plan. The execution plan is a task list of sorts that decomposes a potentially complex SQL operation into a series of basic data access operations. For example, a query against the dept table might have an execution plan that consists of an index lookup on the deptno index, followed by a table access by ROWID.
The EXPLAIN PLAN statement allows you to submit a SQL statement to Oracle and have the database prepare the execution plan for the statement without actually executing it. The execution plan is made available to you in the form of rows inserted into a special table called a plan table. You may query the rows in the plan table using ordinary SELECT statements in order to see the steps of the execution plan for the statement you explained. You may keep multiple execution plans in the plan table by assigning each a unique statement_id. Or you may choose to delete the rows from the plan table after you are finished looking at the execution plan. You can also roll back an EXPLAIN PLAN statement in order to remove the execution plan from the plan table.
The EXPLAIN PLAN statement runs very quickly, even if the statement being explained is a query that might run for hours. This is because the statement is simply parsed and its execution plan saved into the plan table. The actual statement is never executed by EXPLAIN PLAN. Along these same lines, if the statement being explained includes bind variables, the variables never need to actually be bound. The values that would be bound are not relevant since the statement is not actually executed.
You don’t need any special system privileges in order to use the EXPLAIN PLAN statement. However, you do need to have INSERT privileges on the plan table, and you must have sufficient privileges to execute the statement you are trying to explain. The one difference is that in order to explain a statement that involves views, you must have privileges on all of the tables that make up the view. If you don’t, you’ll get an “ORA-01039: insufficient privileges on underlying objects of the view” error.
The columns that make up the plan table are as follows:
Name Null? Type
STATEMENT_ID VARCHAR2(30)
TIMESTAMP DATE
REMARKS VARCHAR2(80)
OPERATION VARCHAR2(30)
OPTIONS VARCHAR2(30)
OBJECT_NODE VARCHAR2(128)
OBJECT_OWNER VARCHAR2(30)
OBJECT_NAME VARCHAR2(30)
OBJECT_INSTANCE NUMBER(38)
OBJECT_TYPE VARCHAR2(30)
OPTIMIZER VARCHAR2(255)
SEARCH_COLUMNS NUMBER
ID NUMBER(38)
PARENT_ID NUMBER(38)
POSITION NUMBER(38)
COST NUMBER(38)
CARDINALITY NUMBER(38)
BYTES NUMBER(38)
OTHER_TAG VARCHAR2(255)
PARTITION_START VARCHAR2(255)
PARTITION_STOP VARCHAR2(255)
PARTITION_ID NUMBER(38)
OTHER LONG
DISTRIBUTION VARCHAR2(30)
There are other ways to view execution plans besides issuing the EXPLAIN PLAN statement and querying the plan table. SQL*Plus can automatically display an execution plan after each statement is executed. Also, there are many GUI tools available that allow you to click on a SQL statement in the shared pool and view its execution plan. In addition, TKPROF can optionally include execution plans in its reports as well.
Trace Files and the TKPROF Utility
TKPROF is a utility that you invoke at the operating system level in order to analyze SQL trace files and generate reports that present the trace information in a readable form. Although the details of how you invoke TKPROF vary from one platform to the next, Oracle Corporation provides TKPROF with all releases of the database and the basic functionality is the same on all platforms.
The term trace file may be a bit confusing. More recent releases of the database offer a product called Oracle Trace Collection Services. Also, Net8 is capable of generating trace files. SQL trace files are entirely different. SQL trace is a facility that you enable or disable for individual database sessions or for the entire instance as a whole. When SQL trace is enabled for a database session, the Oracle server process handling that session writes detailed information about all database calls and operations to a trace file. Special database events may be set in order to cause Oracle to write even more specific information—such as the values of bind variables—into the trace file.
SQL trace files are text files that, strictly speaking, are human readable. However, they are extremely verbose, repetitive, and cryptic. For example, if an application opens a cursor and fetches 1000 rows from the cursor one row at a time, there will be over 1000 separate entries in the trace file.
TKPROF is a program that you invoke at the operating system command prompt in order to reformat the trace file into a format that is much easier to comprehend. Each SQL statement is displayed in the report, along with counts of how many times it was parsed, executed, and fetched. CPU time, elapsed time, logical reads, physical reads, and rows processed are also reported, along with information about recursion level and misses in the library cache. TKPROF can also optionally include the execution plan for each SQL statement in the report, along with counts of how many rows were processed at each step of the execution plan.
The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired. Also, recursive SQL statements issued by the SYS user to manage the data dictionary can be included or excluded, and TKPROF can write SQL statements from the traced session into a spool file.
How EXPLAIN PLAN and TKPROF Aid in the Application Tuning Process
EXPLAIN PLAN and TKPROF are valuable tools in the tuning process. Tuning at the application level typically yields the most dramatic results, and these two tools can help with the tuning in many different ways.
EXPLAIN PLAN and TKPROF allow you to proactively tune an application while it is in development. It is relatively easy to enable SQL trace, run an application in a test environment, run TKPROF on the trace file, and review the output to determine if application or schema changes are called for. EXPLAIN PLAN is handy for evaluating individual SQL statements.
By reviewing execution plans, you can also validate the scalability of an application. If the database operations are dependent upon full table scans of tables that could grow quite large, then there may be scalability problems ahead. On the other hand, if large tables are accessed via selective indexes, then scalability may not be a problem.
EXPLAIN PLAN and TKPROF may also be used in an existing production environment in order to zero in on resource intensive operations and get insights into how the code may be optimized. TKPROF can further be used to quantify the resources required by specific database operations or application functions.
EXPLAIN PLAN is also handy for estimating resource requirements in advance. Suppose you have an ad hoc reporting request against a very large database. Running queries through EXPLAIN PLAN will let you determine in advance if the queries are feasible or if they will be resource intensive and will take unacceptably long to run.

What is the difference between "viewable/ printable payment history" and my "payments received history"? Shouldn't my "payments received" (money verizon got from me) be my "payment history"?

I have not directly myself. One of the reps put me on hold while they said they spoke to finical services. He said they would not turn off my phone while he (the rep) looked into the problem. He couldn't give me a phone # to call him back the next day and told me he would call me instead on my home land line phone #. But what I got the next day was a text message that started with" DO NOT RESPOND" to this text message and it said that I was past due on my account, and that it was due immediately. signed out again with only his first name and no phone # again. Thing is he promised he could help in my first conversation with him, where I had started with "can I speak with a supervisor as I did not want to have to repeat the whole spiel again as he was going to be my third time". He said he was authorized to take care of all & any problems and I did not need a supervisor. I took him at his word and said OK. Turns out like I said earlier…I wasted 2 hours on the phone. Can't find him as I don't know what call center and no last name. I should have gotten that up info front. Hindsight is 20/20.
