Reworded: Running a background program

For example, I have a java program that checks the database if there are any new insertions. The question I want solved is that I want my java program to be executing in the background whether there is another thread or process being executed in my Linux machine. Basically, I want the java program to poll for new insertions. I heard of a command called Thread.Sleep(1000) which pauses the process for 1 second. IS there any other solutions for creating a background polling thread?

The other question is "What do you mean by background?" Runs at system startup time? Runs when you explicitly invoke it? There are several Linux/GNU utilities which will run programs (like the JVM) without interaction, but you have to be a bit more explicit in what you want to do with the program. And, no, Thread. sleep() does not put the task "in the background" - it just suspends it for the specified time period.

Hi Rajani.
ALV require the DRYPOR(screen) for display but incase you run in back ground which have to write to spool but in spool we can only write in format of LIST REPORT not inter-active report like ALV. That why
system cancelled your process immediately.
Hope it helps.

If the program has logic to transfer the data to appliacation layer, then it works. Other wise it is not possible to download the data into your desktop by running in Background.

Getting the variant name when the report program is run in background

Hi All,
How to get the variant name for the report program when run in background? My requirement is to create an email attachement with the name 'variant.XLS', where variant = selection screen variant, when the report program is run in background. The system field SY-SLSET holds the variant name only when run online.
Any pointers to this will be highly appreciated.

Failed to Run OLE Excel program in background JOB (SM36)

Please help.
I have write a program to use OLE to create a Excel file.
The program can run successful in front end workstation. However, when I run the program in background job by SM36.
The statement "CREATE OBJECT EXCEL 'EXCEL.APPLICATION'" return with error "SY-SUBRC = 2".
How can I solve it ?
Can OLE Excel be run on background job ?
Thanks so much,
Mark

Hi Mark:
Your need is a very common one. I also was asked to generate an Excel in Background.
It is not possible to work with OLE in background mode.
The reason is: In background mode there is no presentation server. OLE is executed in presentation server.
Below I paste the code I wrote to solve my problem.
This class sends a mail with an excel attached. The Excel content will be the internal table you pass to the class. But the Excel is not binary, it is a plain text file, separated by tabulators. Anyway, when you open it with Excel, the columns are properly shown.
Sorry. Comments are in spanish, I don't have time to translate it.
I kindly ask to everybody which want to use it to keep my name in the code.

ABAP program to run in Background job

Hi,
We have a custumized program (SO Creation) calling some functions (like: WS_QUERY, WS_UPLOAD, WS_DOWNLOAD, CREATE_TEXT and CALL TRANSACTION VA01) and can only run thru dialog process (foreground). Is it possible to convert it to something that can run thru background job?
Please help.
Thanks.

Hi Deo ,
Unfortunately cl_gui_frontend_services will not work in background.
Please have a look at following information about cl_gui_frontend_services :
The class CL_GUI_FRONTEND_SERVICES contains static methods for the following areas:
File functions
Directory functions
Registry
Environment
Write to / read from clipboard
Upload / download files
Execute programs / open documents
Query functions, such as Windows directory, Windows version, and so on
Standard dialogs (open, save, directory selection)
To Use this, you should be bit familier with OO ABAP Concepts. So I will suggest you to go through with OO concepts of ABAP. It will be of great help to you.

Nikhil

How to make a program run in background?

Is there any ways to make an invisible program with java? a program that is running in background but the user cannot see it and it's not in the Start bar and the user cannot close it.

There are also 3rd party software that lets you install a java program as a service in winnt/2k/xp so that you can start/stop it from the service manager, doesnt even matter if the java program is gui based or not, as there are options (in win2k at least) in the service manager that allows the program to interact (think show gui) or not...one software called JNT comes to mind..
Anyway, if you're using win98/me equivalent, then just use javaw.exe like suggested by previous posters.

Easy Job Scheduling Using BP_JOBVARIANT_SCHEDULE</b>
To schedule a job from within a program using the express method, you need only call the BP_JOBVARIANT_SCHEDULE function module.
The express method has the following characteristics:
Simplified job structure: The function module schedules a job that includes only a single job step.
The function module uses default values for most job-processing options. You cannot, for example, specify a target printer as part of the call to the function module. Instead, the job step uses the print defaults of the scheduling user.
Only ABAP reports can be scheduled. You must use the "full-control" method to start external programs.
The range of start-time options is restricted. Event-based scheduling is not supported.
The function module works as follows:
You name the report that is to be scheduled in your call to the function module.
The function module displays a list of variants to the user. The user must select a variant for the report.
You must ensure that the variants required by your users have already been defined.
The user picks either "immediate start" or enters a start date and start time. Optionally, the user can also make the job restart periodically. The job is then scheduled.
Example
You could use the following code to let users schedule report RSTWGZS2 for checking on the status of online documentation:
call function 'BP_JOBVARIANT_SCHEDULE'
exporting
title_name = 'Documentation Check' " Displayed as title of
" of scheduling screens
job_name = 'DocuCheck' " Name of background
" processing job
prog_name = 'RSTWGZS2' " Name of ABAP
" report that is to be
" run -- used also to
" select variants
exceptions
no_such_report = 01. " PROG_NAME program
" not found.
call function 'BP_JOBVARIANT_OVERVIEW' " List the jobs that
exporting " have been scheduled
title_name = 'Documentation Check' " Displayed as title
" of overview screen
job_name = 'DokuCheck' " Jobs with this name
" are listed
prog_name = 'RSTWGZS2'
exceptions
no_such_job = 01.

How to check in the program that whether it is running in background?

Hi,
Can i check in the program itself that whether it is executing in the foreground mode or background mode?

Check the value of system variable sy-batch. if value of it is 'X' that means program is running in background and if value is ' '(blank) that means prog. is executing in foreground mode.

Program running in background and force shutdown

I have a Pavillion s5220f desktop. I quite frequently get the message that there is a program running in the background and do I want to force a shut down. I have always chosen to force the shutdown. How can I find the program that is running in the background? Also, could this background program cause a more than five minute startup?

Next time it happens take note of what you are doing and what programs are open.
One thing you could do, which will also speed up your start time is to keep non-essential programs from loading when Windows first starts up. Using the Microsoft Configuration Utility, you can selct what programs and processes load at startup.
I don't know which operating system you are using, but here is an HP Support document on using MSCONFIG in Windows 7, the steps are similar for other versions of Windows:

Also, here is an HP video that gives an overview of MSCONFIG:
