Difference between Real Application Testing and Application Testing Suite?

We need to find out average time to execute critical reports. Some reports takes about 24 hours to execute. We want to predict the times of future reports after benchmarking our current DB.
(1.) Which of the 2 should we use (RAT or ATS)?
(2.) What are the differences between the 2?
(3.) Can these products be used in both 10g and 11g DBs?
(4.) Are these 2 ''options'' that come with the DB? or
(5.) Do we have to purchase them separately and install separately?
(6.) Does these tools have Windows interfaces?

Thanks aamat.
Most of our DBs are and will be in 10g. I think it will take at least a year or two to move to 11g. So we are basically stuck with 10g.
So you’re saying we need a 11g DB to run RAT. I.e. you have to install RAT in a 11g. That wont suite our requirements since our DBs are in 10g.
About ATS: The most demanding/frequent requirement from our prospective customers is:
> "We create an ad-hoc report query. How do we find out the time it will take to execute it?"In order to solve this we are hoping to suggest this to our customers:
1.) Replicate the servers and DB (with real data) in another identical machine.
2.) Select about 10 report queries which normally takes a long time to execute.
3.) Execute them and get the times (For single and multiple users).
4.) These will form the benchmark.
*[Q1.]* Now, can our prospective users, use ATS do this. I.e. Can they, the users on their own operate ATS (of course after giving them training)?
*[Q2.]* Can ATS use the output of the previous (i.e. benchmark) SQL queries (with live data) and if given another SQL, estimate the time it will take to execute it?
-- i.e. can ATS compare the tables, SQL query and times of past results and give us an estimate for our new query?
*[Q3.]* If this is not possible in ATS can it be done it RAT? In this case we will have to demand that they upgrade to 11g.

What is the difference between Real-Time (RR) and Time-Sharing (TT)?

Hi Guys,
I am trying to distinguish between LMS process priorities of Real-Time Vs Time sharing and was not able to find any good document explaining me the difference between them. May be one of you Gurus can explain the difference between TT and RR? Any metalink doc id or any url on this issue will be appreciated.
--MM

Hi, Time Sharing scheduling is based on credits that are allocated to the process while creation and as long as process keep consuming the OS resources (CPU etc), its priority keeps on changing dynamically (Because process has lost credits) where as processes with Real Time Scheduling are given priority over other processes configured with Time Sharing (even kernel resources).
In simple terms, if LMS is configured with Time Sharing scheduling on a very busy Oracle RAC system, LMS process may contend for the CPU resources, which may cause performance bottleneck in cluster environment.
In Oracle Real Applicaiton Cluster, various organizations has gained performance benefits of setting few Oracle processes such as LMS with Real Time scheduling.

Difference between Oracle BPEL PM and SOA server suite

Dear Experts,
Right now I am having JDeveloper 10.1.3.4 & Oracle BPEL PM Server 10.1.3.1 with me. Is that two enough to build Business Rules Engine with BPEL process & Human Task Also I having very big question that
Oracle BPEL PM Server and SOA server suite are same or different.
Bcoz, right now I'm have installed only Oracle BPEL PM server.. I didn't see or have SOA server suite.
http://localhost:9700/BPEL/console --------> BPEL console
http://localhost:9700/em ---------> BPEL Enterprise Manager or SOA Enterprise Manager
Please suggest me.
Thanks,
Rajesh

Hi Rajesh,
1--> Right now I am having JDeveloper 10.1.3.4 & Oracle BPEL PM Server 10.1.3.1 with me. Is that two enough to build Business Rules Engine with BPEL process & Human Task.
No, Oracle Business Rules is part of Application Server and as such is installed with SOA Suite. Though with your current Jdev and BPEL PM you can build BPEL Process with Human Task.
2--> Oracle BPEL PM Server and SOA server suite are same or different.
Oracle SOA Suite is a set of tools ( BPEL PM, Oracle Service Bus, Business Rules, CEP, BAM, Oracle Web Services Manager and Jdeveloper).
Oracle BPEL PM is just a component for Orchestration of WebServices.

Difference between unit testing and integration testing

What is the difference between unit testing and integration testing in SAP? Is unit testing takes place in Dev client and integration testing takes place in QA system?
Please clarify
thanks

Hello Krishen,
unit testing means veryfiingsmall / the smallet pieces of software, while integration testing checks the overall functionality of applications. Within the AS ABAP the tool ECATT + manual tests is used for integration tests and the ABAP Unit language integration for unit testing.
When, Who, Where tests are carried out is ultimately a personal decision. As unit tests are operate even under heavy development they are often the first choice for developers, but the unit tests can also serve for regression tests over a long period. Integration tests tend too be created and executed in later stages as they require often a certain majurity of the software under test.
Beside the mentioned links you may check out ABAP Unit infos also in the Wiki.

Difference between application.cfm and application.cfc

Hi,
Can anybody explain the difference between Application.cfm
and application.cfc?
For example:
I have Application.cfm and Application.cfc in the same
folder.
/folder/application.cfm
/folder/application.cfc
/folder /test.cfm
…. And I run the test.cfm.
Which one is executed first?
Thanks,
Krishna

Your last question - Which one is executed first?
The application.cfc will be executed first if you call the
test.cfm. The application.cfm will not get executed.
and, about ur first question... cfm and cfc are entirely
different. You have onRequestStart, onRequestEnd and other events
on cfc. cfc is powerful than cfm.

What's the difference between a web site and a web application?

I'm stumped trying to come up to a difference between a web site and a web application for myself. As I see it, a web site points to a specific page and a web application is more of some sort of 'portal' to content and information.
But where I'm stuck is that a web application is still viewed through a browser (is it not?) and a web site can still view content dynamically, making the line between web site and application prety gray.
For instance, does a web site using ASP.NET or AJAX (I assume ASP.NET is AJAX's proprietary sibling, if not, ignore ASP.NET AND concentrate on the AJAX), becomes a web application because it can retrieve data dynamically and asynchronously or would a website
using PHP and a CMS be more of a web application because it forms the pages on request, based on the request of the client and its content in its databse?
Or maybe I'm totally wrong here - what differenciates between a web application and a website?

This is totally personal and subjective, but I'd say that a website is defined by its content, while a webapplication is
defined by its interaction with the user. That is, a website can plausibly consist of a static content repository that's dealt out to all visitors, while a web application depends on interaction and requires programmatic user input and data processing.
For example, a news site would be a "website", but a spreadsheet or a collaborative calendar would be web "applications". The news site shows essentially the same information to all visitors, while the calendar processes individual data.
Practically, most websites with quickly changing content will also rely on a sophisticated programmatic (and/or database) backend, but at least in principle they're only defined by their output. The web application on the other hand is essentially a program that
runs remotely, and it depends fundamentally on a processing and a data storage backend.

There is no real "difference". Web site is a more anachronistic term that exists from the early days of
the internet where the notion of a dynamic application that can respond to user input was much more limited and much less common. Commercial websites started out largely as interactive brochures (with the notable exception of hotel/airline reservation sites).
Over time their functionality (and the supporting technologies) became more and more responsive and the line between an application that you install on your computer and one that exists in the cloud became more and more blurred.
If you're just looking to express yourself clearly when speaking about what you're building, I would continue to describe something that is an interactive brochure or business card as a "web site" and something that actually *does something that feels
more like an application as a web app.
The most basic distinction would be if a website has a supporting database that stores user data and modifies what the user sees based on some user specified criteria, then it's probably an app of some sort (although I would be reluctant to describe Amazon.com
as a web app, even though it has a lot of very user-specific functionality). If, on the other hand, it is mostly static .html files that link to one another, I would call that a web site.
Most often, these days, a web app will have a large portion of its functionality written in something that runs on the client (doing much of the processing in either javascript or actionscript, depending on how its implemented) and reaches back through some
http process to the server for supporting data. The user doesn't move from page to page as much and experiences whatever they're going to experience on a single "page" that creates the app experience for them.

Difference between Real User Experience Insight and Webalizer?

Dear All,
Can u tell me that is there any difference between Real User Experience Insight and Webalizer?
If both are functioning almost same then why RUEI is expensive
Please must reply

Webalizer uses Web Server logs however RUEI does not use web server logs it monitors Network Traffic without interfering in application which does not affect application performance...
For using Webalizer Application code is modified but not in the case of RUEI
The most important one is that Webalizer does not provide Sufficient and Efficient information as does the RUEI because it can replay the whole session called FULL SESSION REPLAY, Which helps finding errrors on specific pages. Also helps finding delays in transactions.
RUEI is deployed either by copy port or Tapping which create duplicate copy of each request to web server and pass it to RUEI for Analysis

Any real difference between a 1.83 and 2.0 MacBook Pro?

Hi all,
I have recently bought a MacBook Pro 1.83 GHz model. It was on sale at my local computer store and I thought it was a good find, as it was brand new and was selling for £1099, a £300 saving on the 2.0 GHz model. Before I start using it, I just wanted to know if anyone knew if there was a real performance difference between the two and should I have paid the extra £300 to get the 2.0 GHz machine?
I only ask this, as I know that over time Apple sometimes tweak the machine to improve it and (after talking with someone at Apple), I've been told that there have been 5 or 6 changes to the inner workings (or revisions as they called them), and I wondered if this changed the performance or if it was just minor improvements regarding heat and noise and so on.
To finish, does anyone have any speculation as if this is a good time to buy a MacBook Pro with the introduction of the Core 2 Duo chips in the new iMacs?
Many thanks.
MacBook Pro Mac OS X (10.4.7) 1.83GHz Core Duo / 512MB / 80GB

So what you are saying is that the 170 MHZ difference between the 1.83 and the 2.0 is noticeable, but the 160 MHZ difference between the 2.0 and the 2.16 is not?
I thought we were passed the marketing gimmicks and the clock speed race, but I guess not.
Clock speed doesn't tell you anything about the performance of a CPU. Intel almost ran themselves into the ground by trying to pump up their clock speeds and feeding that tripe to the masses. AMD focused on a solid architecture that created a robust chip. As a result AMD took the lead in performance and stability.
Intel's greatest achievement to date has been the PIII Coppermine. So good was this architecture that they have gone back to it. The Centrinos are based off the Coppermines as are the dual cores.
The point of the story is that clock speed means nothing. Save your cash and put it to better use by getting a 7200 rpm drive or more RAM.

Difference between a WEB service and a Enterprise Service?

Can Anybody explain me the difference between a WEB service and a Enterprise Service?

Hi Anilkumar K Naidu ,
Web service
A Web service is a self-contained, modularized functionality, which can be published, discovered, and accessed across a network using open standards and which is supported by SAP NetWeaver. Web services cover services provision for integration within an enterprise as well as cross enterprises on top of any communication technology stack, whether asynchronous or synchronous, in any format.
Web Services in the NetWeaver framework play an important role in facilitating the integration of disparate applications from various departments or trading partners and thus increasing business productivity. This benefit allows small and medium businesses also to integrate their business applications with larger trading partners. The benefit derived from this seamless integration introduces security concerns when all the business logic is now being exposed through a standard interface that is a catalyst for security vulnerabilities. SAP Security Managers must use automated diagnostics tools to ensure that the security vulnerabilities are caught in pre-production and in post-production phase.

Enterprise Service
Enterprise Service-Oriented Architecture (Enterprise SOA)
Enterprise SOA is a blueprint for an adaptable, flexible, and open IT architecture for developing services-based, enterprise-scale business solutions. With SAP NetWeaver as a technical foundation, enterprise SOA moves IT architectures to higher levels of adaptability and moves companies closer to the vision of real-time enterprises by elevating Web services to an enterprise level.
An enterprise service is typically a series of Web services combined with business logic that can be accessed and used repeatedly to support a particular business process. Aggregating Web services into business-level enterprise services provides a more meaningful foundation for the task of automating enterprise-scale business scenarios.

Difference between ALBPM6.0 studio and ALBPM6.0 Enterprise server

Difference between ALBPM6.0 studio and ALBPM6.0 Enterprise server.Can anyone help on this.
Thanks in advance.

Studio is the integrated development and test environment. As such, it's intended for designing processes, creating the UI for the screenflows, creating the objects and introspecting services that you want to tie into the process. Studio has a runtime engine that can be used by a single developer for testing purposes. It runs a little database called Derby and a Tomcat Web Server - again so the work done by a single developer can be tested on the developer's machine at runtime.
Enterprise on the other hand is the production environment. Unlike Studio, it does not have the capability to develop projects. It is the runtime environment where many end users can concurrently run their instances on an industrial strength engine. It can run on a standalone JVM or an application server.
Studio is for development. Enterprise if for Dev/QA/production environments where many users need to hit the engine and many instances need to run concurrently.

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 difference between ADF Task Flow and Faces-Config - when delpoy ?

What is difference between ADF Task Flow and Faces-Config? When I create navigation between pages with ADF task flow then the navigation don't work when I deploy my application to Weblogic 10.3. When I use default server then navigation works fine. With Faces_config in both situations all works ok - on Stanalone server and default.
Where is the problem?
Best regards!

Shay, I don't use both faces-config and adf task flow! When I failed with task flow I tried faces-config.
I have active on my weblogic - adf.oracle.domain(1.0,11.1.1.0.0). This is the right ADF? If yes then where is the problem?
Best regards!

Unit Testing and Integrating testing In HR

Dear Sap Gurus,
Would you be kind enough to give me an example of unit testing and integrating testing?? what do you test, eg..TC and what else.. what happened.??. And also an example of Integrating testing ..and an example ....I know what unit and integrating test is ..and with a good example, i will have a great idea about it ...thanks a lot.

Hi Pooja
Unit Testing:
A process for verifying that software, a system, or a system component performs its intended functions.
Unit transactions are tested against their own specifications and design documents.
Integration Testing
An orderly progression of testing in which software elements, hardware elements or both are combined and tested until the entire system has been integrated.
Integration tests deal mainly with the testing of cross-application process chains in addition to transactions and business processes. The process models and the test cases derived from these form the basis of these tests.
