Executiing program in background..??

Right now, I want to create a background program which monitors certain folder. What I mean by background is that, I want create a program that will continue running on myLinux Machine whether I log on or off (of course the computer willl be on). Also, the program must be executing while I ssh onto the machine or do other command line on the screen.
How would I create the program so that it remains executing in background ?

You need to make no modifications to your program to allow it to run in the background in Unix or Linux.
There are two ways to start the program, depending on which shell (command interpreter) you use:
java com.whatever.GeeWhiz &
or
nohup java com.whatever.GeeWhiz &
Some shells need the "nohup" thing. Try out which one works for you. Or, the latter should work always; the first one gets HUP'ed (killed by a hangup signal) on some shells.

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.

Now i want to call this program from another program that is already exists by using SUBMIT
statement in background and i need to process this program by dividing records by 1000 into seperate session.
how can i do it. Can any body tell me the solution with syntax.
I might get lot of records from above program so i want to split them into diffrent sessions based on number of records(1000).
can any body give me the solution.
Thanks in advance.

Executing a report program in background from another program

Hi Experts,
I developed a report to display material change history based on change date range. Report is taking much time (around 15-20 mins) as I'm hitting CDPOS and CDHDR tables. User wants to execute the report in foreground because he/she can give selection criteria that is required everytime.
So, my requirment is now to create another program with same selection screen elements which will execute the original program in background. In the new program, we will be just capturing the selection elements and will pass them to original program to run in background and display a message to user without wait for the background job to complete. Original program should send an email to an fixed email id with the report output as attachment (for example excel file).
Please suggest.
Thanks in Advance,

Regarding a Change Document Function Module ----- VERY VERY Urgent
When using function modules , I dont think you can directly get data based on material and plant . these function modules usualy works with object class and creation date .
Once you retrieve the data using the function modules you have to filter out the unncecessary data based on your selection screen conditions .

Running BDC program in background for the transaction VL02N

Hi All,
I have coded a BDC program (call transaction method) for the transaction code VL02N. I can able to run the program manually & successfully. But if I execute the program in background(SM36), it is going to dump giving CNTL_ERROR.
Note: I am not using any of the GUI_UPLOAD, GUI_DOWNLOAD funciton modules in the program. But I am using the FTP command funtion modules like( FTP_COMMAND, FTP_CONNECT, FTP_DISCONNECT and FTP_SERVER_TO_R/3).

VL02N is an enjoy transaction. You cant run it in background. Please try VL02.

Call transaction KB21N processed by a program in background mode

Hi to all,
I call transaction KB21N using BDCDATA in a custom program. If I process this program in foreground mode all it's OK, but if I process the program in background mode, I have a runtime error with DUMP: RAISE EXCEPTION with exception condition CNTL_ERROR. This program has to be executed in background so a bapi exist to use instead of call transaction or something else?
Thank you very much,
regards
Antonio

HI Antonio,
The transaction you are dealing with is an SAP Enjoy transaction and for such transactions it is not recommended to do a BDC. YOu should search for a BAPI for the same as you have already identified. Basically the enjoy transactions uses GUI controls which cannot be handled by BDC.
BAPI_ACC_ACTIVITY_ALLOC_POST may serve your purpose.

Run a java program in background

Hi, I am implementing a bot that's supposed to do something when it receives mesages. My question is how I can make the program keep running. I guess the idea of threading would help but I just dunno how to do it. some hints will be appreciated. I dun wanna put a while(true){} there it just takes too much CPU time. I have some Listeners that will do something when some event happens.
examples will be helpful.

I am implementing a bot that's supposed to do something when it receives mesages.Which way does it receive a message? You could run the program in background. It would block on an incoming message. If it listens a socket, you can use
java.net.ServerSocket's accept()
which will block until a connection request arrives.

I have a problem in processing the program in background

Hi,
We have cloned the T'code V_V2 and added some additional functionality and when we try to run the program in background the error is blocking the process
This is because, say example i am tring to process the sales order in production systen through my program ,in that time some one may chage the sales document . in trhis case my program should not blocked it should check the block before processing and then it should proceed.
is there any FM to find the blocked sales order.
Regards,
Vijay

Try using the FM:
ENQUE_READ2
Passing the follwing values:
GNAME --> VBAK (Sales Order header table)
GARG   --> The lock argument
                   (This will be a combination of client number anb Sales Order No.
                    Eg: '3001210000054' where the first three digit i,e 300 is the client No
                   and 1210000054 is the sales order no.)

     Error when attempting to IMPORT object "XVBFA".
What happened?

     This is probably due to an error in the ABAP program.
     When importing the object "XVBFA", the object in the
     dataset had a different type from the target object in the program
     "ZMM_SERVICE_PO" (object types: field, field string/structure, table).

Issue while capturing messages when running program in background

Hi,
I have a program where we have BDC for transaction KSU5 and this is using CALL TRANSACTION method to post the documents after this we have to check a table COEP for the document no's generated in ksu5.
This program works absolutely fine in foreground printing the output on screen the document numbers that we get once we use
CALL TRANSACTION 'KSU5' USING bdcdata MODE 'E' MESSAGES INTO return.
but the same gets spoiled if we run this program in background !! the return table where I use to get the document no it shows additional data of the KSU5 transaction which is not required I am just trying to print the document no from the return table with variable msgv1 and msgv2.
Can someone explain or give solution to run this program in background and get the result printed correctly for the user.
Thanks
Sudharshan

Sudarshan,
I guess your code was recorded for Online mode , try to compare it with Simulated background BDC code for the transaction and see if there is any difference for your required functionality .
You can generate 'Simulated background BDC code' by SHDB->New recording-> and then check 'Simulate background BDC code' option in popup window .

BDC is not working in when executing the program in background

Hi gurus,
I have a problem that in BDC is not working when i'm executing the upload program in background thru scheduling(SM36) , while it works fine when i execute directly with NO screen display mode

Many transactions behave differently when executed in foreground and background. The fields on the screen may be different.
In transaction SHBD when starting a recording there is a checkbox where you can select 'Simulate Background Mode'. If you do your recording using this option you will get the code suitable for background mode. If you do not select this option you will get a code for foreground mode.
By compairing the two codes you will know the changes required for background mode.
Hope this helps you
