Regarding background processing of the session

Hi Gurus
I have some records in my flat file.
While i am doing uploading the file using tc, in foreground it is processing correctly and no issues.
While in Background some of the records are not processing properly and in sm35 for those records I am getting the message :"InCorrect".
What may be the reasons I am not getting.
Can you please suggest me where may be the wrong exactly.
Your suggestions are highly encouragable.
Regards,
kumar

Hi Sree Ram,
This is a very common problem faced in Mass upload of data. This mainly happens if the current transaction is dependent on the previous transaction. For e.g. transaction 2 has a dependency on sucessfull processing of transaction 1.This is due to the time taken by the transaction to update the database table.
Put a commit statement after every transaction in your recording and this will ensure that the records are updated and you will not face any problem in background processing.
Regards,
Guru

Regarding the Mandatory BackGround Processes

Hi,
I wanna to know the information abt the BackGround processes like(PMON,SMON,CKPT,LGWR,DBWR).Can u pls explain abt all these processes and can i able to visualise these processes practically?

To fully outline these processes and what they do, would take a book. In fact, books have been written on the subject.
Go to http://tahiti.oracle.com/ and start with the Concepts manual.

GUI_DOWNLOAD and background processing

Hello,
I have created a process which creates a file. this process uses GUI_DOWNLOAD to put the file on the users C drive or other directory on our network. The user wants to run this process in background and the program is returning a 6 (error unknown) from the GUI_DOWNLOAD FM. I was looking on SDN and found out the GUI_DOWNLOAD only works in foreground. You have to use OPEN and CLOSE DATASET statements to process in background. I am thinking about putting a button to denote foreground/background processing and using the appropriate statements to process the file. I will then have to get the file from the app server to a place will the user can get access to it.
first question - is there a FM to do a FTP from the app server to a directory on our network for the user to access?
second question - is this the right approach or is there something else that I should be doing.
thanks in advance for your help

Hi,
Yes, your right, GUI_DOWNLOAD wil not work in background mode, you need to place the file in Application server, here.
See the below link for a FTP program, use the proper commands(i do not know whether downloading the file is possible through the commands)
http://www.sap-img.com/ab003.htm
or else, write a small program which downloads the data from the application server, but it should run in the foreground

 v_extn.
 SPLIT p_filename AT '.xls' INTO l_filename2 v_extn.
 CONCATENATE l_filename2 'downloaded' INTO l_filename2 SEPARATED BY '_'.
 CONCATENATE l_filename2 'txt' INTO l_filename2 SEPARATED BY '.'.
 OPEN DATASET l_filename2 IN TEXT MODE FOR OUTPUT ENCODING DEFAULT.

 ENDIF.
 LOOP AT it_order_number INTO wa_order_number.
 TRANSFER wa_order_number TO l_filename2.
 ENDLOOP.
 CLOSE DATASET l_filename2.
Now, go to tcode AL11 and check it in the Application server itself.
Hope this helps,

Regarding Background job vs Performance.

Hi all,
I ran 2 similar programs in background through SE30 for comparing the performance.In SM37 the Duration(sec.) for the 2nd program is 3 times less than the first program after execution.But runtime analysis shows the performance of the first program is better than the second program by 1.5 times. Why is this difference!
My question here is, can we consider the time duration shown in SM37 for performance comparison? Why do we get different results in SM37 and SE30?
What factors affect the background process?
Please clarrify.
Regards,
Venkatesh Kumar S.

Hi Venkatesh!
You have overflows. The total in SE30 is just 0.3 sec and 0.4 sec - but in SM37 3086 and 1112 seconds. After a conversion into microseconds, you would have 3 086 000 000 - which is obviously to much.
For such long times, you can only look on the SM37 times - if you like to get more details, make info messages - they will be in the job log with a time stamp and you can inform about 'data read', 'data converted', 'data output' or something like this.

Background Processing? how schedule job for "System Error" Message .

Hello everyone,
in sap help i have read.
http://help.sap.com/saphelp_nw04/helpdata/en/5a/f72040599a8f5ce10000000a155106/frameset.htm
PCK> Monitoring>Message Monitoring-->Background Processing
you can schedule jobs for various background processing:
●     Archiving of messages processed successfully
●     Deletion of messages that are not to be archived
●     Restarting of messages with errors
●     Rescheduling of lost messages
can anyone understand this docu?
give me some introduction, how can i define and schedule these jobs ?
thx in advance!!
best regards
Yaning

Background Processing
Prerequisites
You have started the message monitor on the initial screen of the PCK and are in Background Processing.
Features
Archiving
You require two archiving sessions to archive messages:
●     One session to write the messages to the archive
●     One session to delete the persisted messages that have been archived
To do this, you schedule an archiving job, which implicitly schedules the sessions to write to the archive and delete the archived messages.
You can define one or more rules for each archiving job; these rules contain conditions that a message must meet in order to be archived by the job. At least one of the defined rules must be met for archiving to take place.
All information that is displayed for a message in message monitoring is archived, in addition to the audit log for each message.
Deleting
A standard delete job is created automatically. It runs once a day. You can schedule additional delete jobs; however, you cannot define rules for them.
Restarting
Instead of restarting messages with errors manually with message monitoring, you can schedule a job to automatically restart these messages. This is possible for all messages for which the number of defined restart attempts has been exceeded (messages with the system error status).
You can define one or more rules for each job to restart messages; these rules contain conditions that a message must meet in order to be restarted by the job. At least one of the defined rules must be met for archiving to take place.
Rescheduling
A standard job to reschedule messages is created automatically. The job runs once a day and ensures that messages lost as a result of database failure, for example, are rescheduled. You can schedule additional rescheduling jobs; however, you cannot define rules for them.
Thx Aamir.
But I mean the messages with errors in Adapter Engine , not in Intergrations Engine.
the situation is like Naveen Pandrangi's WebLog
II. Errors in Adapter Engine [XI : How to Re-Process failed XI Messages Automatically|XI : How to Re-Process failed XI Messages Automatically]
I
Till now we have seen how to resubmit/restart message that failed in Integration Engine. One a message makes it from Integration Engine to Adapter Engine, the message is flagged as checked in Integration Engine. The status of the message in Adapter engine does not effect the processed state in Integration Engine. Now if this message was asynchronous, XI will by default try to restart the message 3 times at intervals of 5 minutes before the status of the message is changed from Waiting to System Error .
*how can i schedule a job to automatically restart these messages with errors?
best regards

ABAP trail 7.00 timeouts and background process

Does anyone knows if it's possible to change the number of dialog and background processes?
And the transaction to change the timeouts of such processes?
Thank you

you can change the timeout in rz11.Parameter-name is rdisp/max_wprun_time. Backgound processes habe no timeout, so this value is only valid for dia-processes
To change the number, you have to adjust your instance profile. In the forum 'Netweaver Administrator' should be some information about that. So just the short hint: you can adjust the profiles in RZ10, but have to do some steps for that. Just search in NW-Admin-forum above.

How can I run a method as a background process?

Hello,
I am currently working on a report where depending on the number of items selected, the user may choose to process all the items right now or as a background process.
How can I do that in ABAP?
Thanks

To run a job in the background it has to be scheduled as batch job. You would usually do that using transaction SM36. As I understand your problem you want to schedule such a job directly from your coding. You may want to have a look at function group BTCH. It overs quite a few FMs to programmatically add a batch job.

Hi,
FM GUI_UPLOAD doesnt work in background, use dataset to upload it from application server.
refer below code

*--Read the data from application server file.
OPEN DATASET l_file FOR INPUT IN TEXT MODE ENCODING DEFAULT.
IF sy-subrc NE 0.
*--Error in opening file
    MESSAGE i368(00) WITH text-005.
ENDIF.
*--Get all the records from the specified location.
DO.
    READ DATASET l_file INTO l_line.
    IF sy-subrc NE 0.
      EXIT.
    ELSE.
      SPLIT l_line AT cl_abap_char_utilities=>horizontal_tab
                      INTO st_ipfile-vbeln

Background processing needed...

iWeb needs to background process.
Each shape/rollover/png/navbar/image-resize file needs to be generated as you make it, or in the background if you're working fast. Every time you alter the item's size or appearance on the iWeb page, it should regenerate it, but if you don't alter the item it leaves the generated file untouched. Moving the item on the iWeb page should not alter the already generated file. Altering plain text on a page should not change anything, only the html file.
There should be an info page like iDVD informing you of background encoding status. You can however save at any time (like iDVD).
When you come to publish, it should generate all other items that have changed or not yet been background encoded (as it does now).
Next time you open iWeb to work on it, all encoding is all up to date (as it did it all prior to publish), so any items that have not been changed should be untouched, and only new items need to be encoded and hence published.
That way, only changed items are generated, not the whole shebang. Thus saving everybody's wasted time and effort in uploading/finding changed files etc.
It should be perfectly possible as iWeb has an undo and a restore feature, so it is already keeping track of changes all the time.
What do you think, will this be in iWeb 1.2, iWeb 2.0, or Web Studio Pro 1.0 ?

Hi,
This is the F1 documentation for calling a FM in Update task
Flags the function module func for execution in the update task. It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task.
This is the F1 documentation for calling a FM in background task
Flags the function module func to be run asynchronously. That is, it is not executed at once. Instead, the data passed using EXPORTING or TABLES is placed in a database table and the next COMMIT WORK executes it in another work process.
Hope this helps

Background processing in Flex

I have two questions here. But, I guess they both are related
1. I have a calendar application, where I display set of
events based on time for a day. I need to start a background
process to check if any of the events are scheduled for the next
half an hour and show the reminder to the user.
Like I mentioned, I believe that there should be a background
thread running to check the current day event's time against the
local time and display reminder.
2. Next question is, I have a search component, where the
user enters the text and clicks on the search to fetch the results
based on the text entered.
I need a little customizable behavior here, where I need to
fetch the results based on the user input automatically(without
clicking the search button) based on the time lag after the last
character entered.
Any help/views in this regard is highly appreciated.
Thanks In Advance,
Suresh.
