Differences in Background jobs and Dialog jobs

Hi everyone,
I am new to SAP and would like a little clarification regarding what is meant by Background jobs and Dialog jobs/processes. We had a situation at our client location where the system got completely bogged down to the point that it almost froze and many of the process chains were failing in BI. As per the basis team, the jobs were triggered as "dialog jobs" instead of "background" jobs which caused a heavy load on the system.
What is the difference? What happens when the jobs are run in the background or as dialog? Can both be checked in SM37?
Points will be awarded
Thanks.

**Dialog Work process:** The Dialog work process fulfill all requests for the execution of dialog steps triggered by an active user. The dialog work process are not used for request which take long time and which use more cpu. Every dispatcher requires at least two dialog work processes. The dialog work process default time is 300 secs. If the dialog work process does not respond in this time, it will be terminated. Also dialog work process are multiplexed to handle large no of user request.
**Background Work process:** The background work processes execute programs that run without user interaction. At least two background work processes are required per SAP system. More than one background work processes can be configured per dispatcher. Usually the background work process are used for carrying jobs that take long time to finish, like client copy, client transport etc.., . There are two types of background work process. They are A type and B type. A type background work process are used for mission critical jobs. Background jobs of priority a have high priority than B type back ground jobs.
you can check your job using tcode SM50.
Thanks

Different Subroutines in Background jobs and Dialog jobs

Hi guys,
I want to execute some subroutines when the program is running using a background job , and some other subroutines completely different when the user use dialog job ( program -> execute in background ) . I know that sy-batch = 'X' in both cases , but, there is something else to identify them ? , any ideas .
thank you .

It will be - he meant that they start the background job from SE38/SA38 not run it online.
SY-SLSET is a starter point for checking the variant used - dynamic variants are used when you don't pick one from the list. However, this would not help if the user picked a variant and then scheduled the job dynamically. Another option is to use function GET_JOB_RUNTIME_INFO in your program. Assuming your scheduled jobs are named differently, you can check for the condition by checking the name of the running job. Dynamically created jobs will have the program name as the job name.

What is the difference between background job and foreground job

Hi Experts,
Could you pls tell me
What is the difference between background job and foreground job
and where exactly used background jobs...
Thanks

Hello,
Background jobs - without user interaction, scheduled via SM37.
Foreground jobs - with user interaction (transactions).
For more information, please read these: [http://help.sap.com/saphelp_nw04/helpdata/en/e4/2adbda449911d1949c0000e8353423/frameset.htm], [http://help.sap.com/saphelp_nw04/helpdata/en/73/69ef5755bb11d189680000e829fbbd/frameset.htm] and [https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20cb0b44-8f0b-2a10-2381-ca8162bcb5b2].

Broken jobs and failed jobs

hi all..
please tell me difference between broken jobs and failed jobs
thanks

Please refer documentation .
Failed Jobs
If a job has the status of FAILED in the job table, it was scheduled to run once but the execution has failed. If the job was specified as restartable, all retries have failed.
If a job fails in the middle of execution, only the last transaction of that job is rolled back. If your job executes multiple transactions, you need to be careful about setting restartable to TRUE. You can query failed jobs by querying the SCHEDULERJOB_RUN_DETAILS views.
Broken Jobs
A broken job is one that has exceeded a certain number of failures. This number is set in max_failures, and can be altered. In the case of a broken job, the entire job is broken, and it will not be run until it has been fixed. For debugging and testing, you can use the RUN_JOB procedure.
You can query broken jobs by querying the SCHEDULERJOBS and SCHEDULERJOB_LOG views.

What is released job and scheduled job?

Hi BW experts,
Please let me know what is released job and scheduled job?

Hi
<b>Released job</b>:The job has been fully defined, including a start condition. Without a start condition, a job cannot be released.
Only an administrator or a user with appropriate authorizations for background processing can release a job, preventing unauthorized users from running jobs without approval.
<b>scheduled job:</b> The job which is scheduled for a particular time and that will come into the queue of jobs to which time it is scheduled.
U can see these jobs in SM37 tcode

What is difference between report programming and dialog programming?

hi,
what is difference between report programming and dialog programming? plz provide some example code
bye

ABAP programming
Basically reports are used to read database and represent the results in lists.
Reports are collections of processing blocks that the system calls depending on events.
We can use reports to evaluate data from database tables.
Reports are stand alone programs and controlled by events.
A report itself never creates events
steps in report:
Processing the selection screen
Reading the database
Evaluating the data and creating lists
Outputting a list.
1st u write simple logics, after that u can enhance the code as step by step.

Dialog Programming
Structure of a Dialog Program
A dialog program consists of the following basic components:
Screens (dynpros)
Each dialog in an SAP system is controlled by dynpros. A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).
The screen layout fixed in the Screen Painter determines the positions of input/output fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.
ABAP/4 module pool
Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.
All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.

Differences between ABAP Programming and Dialog Programming

Can any one explain me the Differences between ABAP Programming and Dialog Programming

Hi,
ABAP PROGRAMING:
An ABAP program consists of individual ABAP statements. Each statement begins with a keyword and ends with a period.
PROGRAM FIRST_PROGRAM.
WRITE 'My First Program'.
This example contains two statements, one on each line. The keywords are PROGRAM and WRITE. The program displays a list on the screen. In this case, the list consists of the line "My First Program".
The keyword determines the category of the statement. For an overview of the different categories, refer to ABAP Statements.
You can execute different parts of programs conditionally or in loops using the standard keywords IF, CASE, DO, and WHILE.
When controlling the flow of an ABAP program, remember that the structure of the program is made up of processing blocks that cannot be nested. This section describes how to control the flow of a program within a processing block. The keywords covered here do not allow you to branch outside the processing block in which you use them. You can regard this as internal control of an ABAP program, as opposed to the external control provided by events in the ABAP runtime environment.
To control the internal flow of a processing block, you can use control structures to divide it up into smaller statement blocks according to the principles of structured programming.
DIALOG PROGRAMING:
This is a classical programming method that is based on dynpros and dialog transactions.
Classic Application Programming
Separating the application layer from the presentation layer means that when you run an ABAP application program requiring user interaction, control of the program is continually passed backwards and forwards between these layers. While a screen is ready for input, the corresponding SAP GUI of the presentation layer is active. During this time, the application layer is not active for the application program. Therefore, the ABAP application servers are free for other tasks. Once the user has entered data on the screen, program control passes back to the application layer. Now, the presentation layer is inactive. The SAP GUI is still visible to the user during this time, and it is still displaying the screen, but it cannot accept user input. The SAP GUI does not become active again until the application program has called a new screen and sent it to the presentation server.
Consequently, if you use this method, you need to divide dialog programs into single dialog steps, with each of these steps comprising the programming logic between two successive screens.
REGARDS,
VASAVI.
KINDLY REWARD IF HELPFUL.

Batch job and background job

Hi
what is the difference between a batch job and backgroun job ??
thanks
kumar

hi kumar,
As far as I know
Batch job are the jobs created with sessions. You can process those sessions in SM35. These are not direct update methods.
Where as the background jobs are the jobs running in the background with out user interaction. Once you schedule the job for the background job it will run with out user interaction according to the given schedule.
You can run the batch jobs also in background.

CS4 Media Encoder batch jobs, and .avi ffdhshow

I have two distinct, but slightly related questions to ask.
First I should point out: I've used Premiere and After Effects for creative purposes before, but today I am using Adobe software for a more practical purpose: some engineering research work. Essentially, I have thousands of hours of video to process, I have all the firepower needed to perform it, I am currently limited by the ammount of time I am stuck clicking away at the computer.
Essentially my job right now is to convert and concatonate 1 minute segments into larger cohesive files. I say convert because the supplied files are encoded as .avi with an obscure proprietary surveillance video format (Mavix, for those of you familiar, doubt it though, even a google search won't bring up anything). It's okay, I have the VFW installed and so far I've been doing fine (if not slowly) pre-converting to NTSC DV default with AME CS4 and then importing into VDub (handy because of it's automatic file appending feature) at which point I compress with ffdshow (gave me the best performance considering quality, compression and processing perfromance). Vdub is also handy because I can take better advantage of multi-cores (8 per machine) by running Vdub jobs and AME jobs simultaneously. I am still amazed how mult-tasking on these machines gets me absolutly no performance hits.
Why is it that I am using AME? It seems to be the only thing that can decode these Mavix files (I've tried them all). And only a direct convert through AME... if I open it up in premiere first, then export it, the video glitches.
Question 1:
Right now, the biggest challenge is batch converting videos. I can drag up to 70-75 videos (regardless of hardware) into AME before it starts rejecting files. I would like for it to pre-process thousands of them at a time automatically. Any ideas how the queue size can be increased or how I can properly batch convert thousands of files at a time? Checking back at a computer every 20 minutes for a week is a real waist of time when I could leave it sit over the weekend in a corner and do it's thing.
Question 2:
I wanted to reuse the concatenated files that Vdub spat out (.avi ffdshow H.264 -> no comments please, I have a good reason for doing this) for some other work. I just want to know if it is possible to get Premiere to work from these files directly or if I have to reconvert them to somethign else first. So far, importing them yields black video.

Hi,
I have absolutely no experience with this...but as to question number 2... I did a google search on ---avi ffdshow h264 cs4 ----and found this info
As you probaby know a lot of people using premiere are adament about NOT loading codec packs, and in particular ffdshow and k-lite...but you probably know that or you might not have said " no comments please "....etc.
That said, there is a part of the following stuff that says something about using cs4 with ffdshow with h264 enabled in the video and something enabled in the sound.. and then the reference to K-lite...but that k-lite post was using ( at that point ) a different editor I think...so take this with a grain of salt and maybe check the ffdshow enabled setting so you can see your video in PP...
Good luck ....and I hope your computer doesnt explode or anything bad happens...which might mean a total reformat and reinstall etc...

For simple edits, you can use vdub (see above)
If you need a NLE, Vegas Pro 8 will work, if you have ffdshow (h.264 enabled) or x264vfw, but it won't see the audio. So you can open it in vdub and save the audio as wav then import into Vegas
Premiere Pro CS4 will work, but you need ffdshow (h.264 enabled in the video configuration and MSADPCM enabled in the audio configuration)
Cheers

Hi, I just bought a Creative Vado HD and I have 3 clips I just want to paste together.
I downloaded Virtualdub, downloaded x264vfw, downloaded ffdshow (h.264 enabled) and installed all three. I still can't open any of the Vado HD clips into Virtualdub. I get an error message. Is there another step I am missing?
Thanks in advance!

do you have this version installed?
http://sourceforge.net/projects/x264vfw/
if that doesn't work for you , enable h.264 in the ffdshow vfw decoder interface (yellow icon, not red icon), because vdub relies on vfw , not directshow ( ROBODOG2 NOTE ----GRAPHIC BELONGS HERE.....SEE BELOW )

@poisondeathray - yes that helped! thank you!!!
Now that I am able to "edit" my Creative Vado HD videos in Virtualdub, I notice something very strange. Each video clip is approx 30 seconds long. The total combined/merged clips should be approx 2:30 long. However, windows media player (as well as right clicking for properties) says the video is WAY longer than it should be (like 11 min long)!!!
Anyone else notice this? Is this a virtualdub mistake or human error on my part?

Did you do any editing or just append the clips? If you edited portions did you cut on keyframes?
Did you set "direct stream copy" for video & audio?
What do other media players (e.g. vlc, kmplayer, smplayer) and mediainfo say about the joined clip ?

Has anyone found a solution to this issue yet? I can't believe Creative would release a product like this with almost no 3rd-party support. I really wanted to get this camera, but this is a deal-breaker. I managed to get a few raw files from the Vado HD to test. They work fine just for playing in WMP, but I cannot edit the videos in any program I tried. Adobe Premiere CS4 doesn't work. You see the audio but no video. If you try to do basically anything it crashes. Sony Vegas 9 doesn't work either. Same deal, audio with no video. Same issue in VirtualDub. I have ffdshow installed and H.264 is enabled (libavcodec). Do I have any other options here?

Download and install K-Lite mega codec pack. The ffdshow configuration will be pretty streamlined so you likely won't have to screw around with it after the install.

Difference: Job run in foreground, job run in background and batch job

Hi Gurus,
Can you please help me to know what are the differences between job run in foreground, job run in background and batch job? Do jobs in foreground run in presentation server? Do jobs in background or batch jobs run in application server?
Thanks,
Kumar

foreground job running may cause job running crash or failed if it is too big or server is busy and it take too long time. meantime it will take one sap session.
background job will run base on request server status. and it will not take your sap session. and it will not failed normally.
and you can get the result by SM37.
my experience show that big report run in background normally faster than in foreground.

Difference between Batch jobs and background jobs...

hi APO Gurus ....
This may sound a very silly question. What is the exact difference between a batch run and executing a background job ?

If i understand correctly your question is executing a program (for example) in background and running in a batch jobs. You can execute a program in background while you are online, go to menu program->execute in background and enter print parameter, schedule parameter. System creates and starts job dynamically. You can check in SM37. Batchjob is you create job using SM36 (with program and Variant) define run frequency. System automatically run job in specified frequency. I my experience, technically both are same, system behaves exactly same. One dynamically creates job other one runs on predefined freq.
Thanks,
Niranjan

Difference between batch job and Background Job

Hi Forum,
Can anyone distinguish between batch job and background job for me please ?
SK

Hi,
Batch Job:
A batch job is a process that runs in the background, often deferred and unattended, to process data in groups (batch) rather than by individual transactions (e.g. a monthly phone bill rather than a bill for each individual phone call). A batch job executes a sequence of programs and technical instructions that are stored in a command file. Progress and error messages are output to a log file allowing users to determine, at any time, if the batch job completed successfully or identify the cause of the problem. Because batch jobs run in the background they are less visible to the end user.
In a business-computing context, batch job scheduling implies the automatic execution of background tasks (batch jobs) at pre-determined points in time (e.g. every day at 8pm, midday on Wednesday).
3 types of batch job scheduling can be distinguished: native, basic and advanced batch job scheduling.
Most operating systems and some business solutions software come equipped with native batch job scheduling tools that provide a limited service (e.g. Windows Scheduled Tasks, UNIX crontab, SAP CCMS) locally to each installation. However, business processes may span multiple platforms, applications, countries and companies. Their complexity may require much more functional power as provided by basic batch job scheduling including national and regional variations in the working calendar, sequence variations according to the day of the month, triggering of jobs by the successful completion of preceding jobs, elimination of gaps and reduced batch windows. Major benefits of basic batch job scheduling are enhanced productivity, operations reliability and cost-reduction. For e-business applications that require real-time processing, the distance between interactive individual processing and batch processing tends to decrease. Advanced batch job scheduling can handle these advanced requirements: event-driven scheduling for a real-time synchronization with interactive processing, just-in-time scheduling to run operations as soon as possible, cross-platform and cross application services for the entire IT landscape, real-time overall monitoring to track background operations for all applications on all servers.
The standard benefits of batch job scheduling are drastically amplified when job schedulers can handle the end-to-end automation and monitoring requirements for all background operations.
To schedule a back ground job follow the below steps:
1. Use Transaction SM36.
2. Assign a job name.
3. Set the jobs priority, or Job Class:
High --- Class A
Medium --- Class B
Low ---Class C
4. Here you can specify,when the job is to start by choosing Start Condition. If you want the job to repeat, or be periodic, check the box at the bottom.
Else click on the immediate and save this.
5. Now,define the jobs steps by choosing Step.
Here you need to give the ABAP program that has been used and the name of the variant thats being used.
6. Save the fully defined job to submit it to the background processing system.(You need to click save button on the main screen i.e SM36)
7. When you need to modify, reschedule, or otherwise manipulate a job after you've scheduled it the first time, you'll manage jobs from the Job Overview.
8. Release the job so that it can run.
The job, even those scheduled for immediate processing, can not run without first being released.So,do remember to release.
Hope this helps you.
Regards,
Rakesh
