Error in handling Print Params In Parallel Processing of background jobs

Hi Friends,
My requirement is to optimize the performance of standard pgm RELEABL1 that takes a long time to complete when scheduled in background,and for that i have created a zpgm which will split the input data and run the jobs in parallel . I am using the submit statement and JOB_OPEN and JOB_CLOSE function modules to schedule the standard prg RELEABL1 in background with the input from my zpgm. The problem here is there is a push button " PRINT PARAMETERS" near the execute button on the selection screen of the standard pgm RELEABL1 in which the printer details have to be mentioned. Whenever i schedule the job in backgroung it throughs an error stating that " Define the Print Parameter First " . I tried my luck with all possible combinations but not able to handle this through my zpgm.....otherwise my pgm works fine. Can someone please guide me on how to handle this print parameters either through submit or what ever way possible.
Thanks & Regards,
Balaji.K

Hi Balaji,
We have the same performanced problem. 8 processes in parallel, still suffers from bad performance. How many subscribers are there on the system and how many processes do you use ?

How to print result of transaction processing in background job?

Hi experts,
Could you give me advice how to resolve following task:
I need to print a list of sales orders (transaction VA05) in background job.
Are exist standard techniques for this? Or should I create new program (report) and create the job with printing of parameters?
Thanks for advance

Hi,
Define a background job with the program name & variant.
Pass the print specifications as well.

Need help with parallel process in background; not able to call FM in bgnd

Hello,
I am trying since 2 days to solve the issue of parallel process in background without using FPP.
For which I want to call function module of class method in new task but to be processed by background process and not dialog.
I searched so many websites but everyone has suggesteed to 'call function in background task' . But the fact is the processing of function happens by dailog process even in this case.
I want to loop at table and call FM or class method inside each loop.
Kindly suggest me how can I call function or class method in new task in everycall and prcoess it in background.
thanks

Balaji,
Is the name of the button between single or double quotes?

Parallel processing in background

Hi All,
I am processing 1 million of records in background, which takes approximately around 10 hrs. I wanted to reduce the time to less than 1 hr and tried using parallel processing. But the tasks run in Dialog workprocesses and giving abap short dumps due to time out.
Is there any other solutions using that i can reduce total processing time.
Please note that i cannot split. I am getting 1 million records from a select query and after processing all those records in SAP, I am sending to XI and XI will post in legacy system.
Please note that all other performance tunings done.
Thanks,
Rajesh.

Hi Rajesh,
Refer sample code for Parallel Processing:
By doing this your processing time will be highly optimized.
Go thru the description given in the code at each level.
This code Checks available WORK PROCESSes and assigns data in packets for processing. This way you save a lot of time esp when data is in Millions.
Hope it helps.

Parallel processing in background using Job scheduling...

(Note: Please understand my question completely before redirecting me to parallel processing links in sdn. I hve gone through most of them.)
Hi ABAP Gurus,
I have read a bit till now about parallel processing. But I have a doubt.
I am working on data transfer of around 5 million accounting records from lagacy to R/3 using Batch input recording.
Now if these all records reside in one flat file and if I then process that flat file in my batch input program, I guess it will take days to do it. So my boss suggested
to use parallel processing in SAP.
Now, from the SDN threads, it seems that we have to create a Remote enabled function module for it and stuf....
But I have a different idea. I thought to dividE these 5 million records in 10 flat files instead of just one and then to run the Custom BDC program with 10 instances which will process 10 flat files in background using Job scheduling.
Can this be also called parallel processing ?
Please let me know if this sounds wise to you guys...
Regards,
Tushar.

Thanks for your reply...
So what do you suggest how can I use Parallel procesisng for transferring 5 million records which is present in one flat file using custom BDC.?
I am posting my custom BDC code for million record transfer as follows (This code is for creation of material master using BDC.)

Process Chain background jobs

Hi All,
we got a typical issue in Process Chain, every day process chain triggers in the midnight, and yesterday morning It got failed while activating DSO for HR data, and we observed that the jobs are running in the background for longer time (there are 3 jobs related to HR still running since around 24 hours). In order to run the following processes which are no way related to HR, we made turning red to Finish (to skip this process - using Function module RSPC_PROCESS_FINISH) to make sure other reports work perfectly. yesterday PC ran successful expect HR data.
Today morning we observed that the jobs are still running and also PC gets stopped in deleting contents of HR (after this we are loading HR DSO) . the process neither failed nor success. we checked in Sm37 and observed that job related to Delete content of HR data is also still running and in active status.
it is not allowing us to skip the process as we did for the HR DSO. So we thought to kill the job and Killed the JOB of delete content of HR data, and tried refreshing in Process Chain. But the variant is empty now and process stopped at before the Delete contents (which are another deleting cubes) now the process is at delete contents of CUbe (which is before step to the delete HR DSO), if we right click and check the options it is showing display variant and display messages.
We repeated the Process chain again it stopped at delete content HR DSO(back ground job running again and running longer time), the process is at delete contents DSO HR, (showing the box half filled).
how to skip this delete contents of HR data DSO, because we don't want to stop all the following processes(which are not related to HR) and how to make my PC ran successful (expect HR) to make my report working perfectly expect HR reports
Thanks in advance,
Teena

Thank you for the reply,
Yes we can create PC for HR seperately.
Presently the thing is yesterday we din't loaded the HR data (as we skipped the process by forcefully finished the process using FM -RSPC_PROCESS_FINISH) , As the jobs are still running morethan 26 hours. Now DSO HR doesn't have any data, but the process has been stopped at the deleting the content of HR data (our assumption since the HR loading jobs running longertime causing this, job delete content HR is also active and running (while loading it is trying to delete it, so it might be locked)
But we need to skip the process of HR delete content now, inorder to run other process successful, (we can create other HR PC later) but can you suggest the solution for now.
Thank you,
Teena

Disabling parallel run of background job

Hi All
I have an ECC6.0 system in load balancing mode with cluster environment. The problem is that we have a program which runs in background. The same is specified to run on App1 server. However, in case the no. of bkd processes are less in App1 servers, it schedules the remaining jobs on to App Server 2 which is not desired.
eg
I have a process which activates 8 bkgd jobs on App1
App1 only has 5 bkgd processes free
The remaining 3 jobs will get scheduled on App2, which is not desired.
Please let me know how can i restrict a background process to run only on a single server.
Regards
Lokesh.

If you define/change a job you can give a background server, however, if you give a fixed instance name and that instance is down the job won´t run at all.
You may be able to use an external scheduling software for this, e. g. Redwood Cronacle - which is free for Netweaver customers.

How to define "leading" random number in Infoset fpr parallel processing

Hello,
in Bankanalyzer we use an Infoset which consists of a selection across 4 ODS tables to gather data.
No matter which PACKNO fields we check or uncheck in the infoset definition screen (TA RSISET), the parallel frameworks always selects the same PACKNO field from one ODS table.
Unfortunately, the table that is selected by the framework is not suitable, because our
"leading" ODS table which holds most of our selection criteria is another one.
How to "convince" the parallel framework to select our leading table for the specification
of the PACKNO in addition (this would be times 20 faster due to better select options).
We even tried to assign "alternate characteristics" to the packnos we do not liek to use,
but it seems that note 999101 just fixes this for non-system-fields.
But for the random number a diffrent form routine is used in /BA1/LF3_OBJ_INDEX_READF01
fill_range_random instead of fill_range.
Has anyone managed to assign the PACKNO of his choice to the infoset selection?
How?
Thanks in advance
Volker

Well, it is a bit more complicated
ODS one, that the parallel framework selects for being the one to deliver the PACKNO
is about equal in size (~120GB each) to ODS two which has two significant field which cuts down the
amount of data to be retreived.
Currently we execute the generated SQL in the best possible manner (by faking some stats )
The problem is, that I'd like to have a Statement that has the PACKNO in the very same table.
PACKNO is a generated random number esp. to be used for parallel processing.
The job starts about 100 slaves
Each slave gets a packet to be processed from the framework, which is internaly represented
by a BETWEEN clause on this PACKNO. This is joined against ODS2 and then the selective fields
can be compared resultin in 90% of the already fetched rowes can be discarded.
Basicly it goes like
select ...
from
ods1 T_00,
ods2 T_01,
ods3 T_02,
ods4 T_03
where
... some key equivalence join-conditions ...
AND T_00.PACKNO BETWEEN '000000' and '000050' -- very selective on T_00
AND T_01.TYPE = '202' -- selective Value 10% on second table
I'd trying to change this to
AND T_01.PACKNO BETWEEN '000000' and '000050'
AND T_01.TYPE = '202' -- selective Value 10%
so I can use a combined Index on T_01 (TYPE;PACKNO)
This would be times 10 more selective on the driving table and due to the fact,
that T_00 would be joined for just the rows I need, about a calculated time 20-30 faster.
It really boosts when I do this in sqlplus
Hope this clearyfies a bit.
Problem is, that I can not change the code either for doing the
build of the packets or the one that executes the application.
I need to change the Inofset, so that the framework decides to build
proper SQL with T_01.PACKNO instead of T_00.PACKNO.
Thanks a lot

Parallel Processing in Oracle

Gurus,
I need to run three cursors at a time. Is it possible in Oracle?
If yes then help in this issue.
Thanks in Advance.

As mentioned, it all depends on whether the results of the 3 cursor processes need to be combined/processed afterwards.
If not, and each cursor process is a independent process, then you can define each of the 3 processes as procedures.
The "main process" can then simply use the Oracle Job Scheduler to start once-off jobs for these 3 PL/SQL procedures. These will then run in parallel, as batch/background jobs.
If the "main process" needs to wait for some reason for these 3 processes to complete processing (and commit their changes), then the following loop structure can be used:
loop
exit when <all 3 jobs have terminated>;
-- if not. sleep for n seconds and then check again
DBMS_LOCK.Sleep( n );
end loop;The check for <all 3 jobs have terminated> can be done using SQL to query the USER_JOBS view.
When the 3 jobs were submitted, each returned a job id. When this no longer exists in USER_JOBS, that once-off job has completed processing.
If each of the 3 jobs needs to communicate with one another via some kind of IPC mechanism.. things are more complex. Not because of PL/SQL or Oracle, but because this is a complex thing to code in any language and system.
Oracle provides a couple of IPC-like mechanisms. These include:
- DBMS_PIPE
- plain vanilla SQL table as "a shared memory area"
- advance message queues
The only real difference is that where you would have coded a fork() in Unix or a CreateThread() in Windows, you will be using DBMS_JOB (or DBMS_SCHEDULER) to spawn a thread.
The rest of the concepts of multi-threading/multi-processing remains the same. Thread safe code. Semaphores. Mutexes. Etc. The basics remains the same.. just the actual "things" used to implement these are called by a different name.

Pointers for optimizing system performance (run time) while running DP process chain with parallel processing

Hi Experts,
We are running APO DP process chain with parallel processing in our company, we are experiencing some issues regarding run time of process chain, need your help on below points;
- What are the ways we can optimize process chain run time.
- Special points we need to take care of in case of parallel processing profiles used in process chain.
- Any specific sequence to be followed for different processes in process chain - if there is some best practice followed.
- Any notes suggesting ways to improve system performance for APO version 7 with different enhancement packs 1 and 2.
Any help will be really appreciated.
Regards

HI Neelesh,
There are many ways to optimize performance of the process chains (background jobs) in APO system.
Firstly I would recommend you to identify the pain areas (steps) which are completing with more runtimes. Then each one of the step has got different approaches to decrease the runtime.
Like you may end up with steps like infopackage executions, DTPs, DP mass processing jobs etc which might be running with more runtimes. So now target each one of them differently and find out the ways to optimize. At the same time the approach you follow should be technically possible with basis perspective (system load and utilization) as well.
And coming to parallel processing, you can use parallel processing for different for different jobs. You can further r explore on the same using parallel processing. Like loading an infocube, mass processing, infopackage execution, DTP, TSCOPY etc.
Check the below link for more info

Let me know if you require further info.

Best way to go for Parallel Processing?

Hi all,
I am working on a ALV report, where the user will be selecting some entries and click on process button.
Currently, the entries are processed sequentially in a loop. Now, to save time on processing, the entries have to be grouped by material number, and all the groups have to be processed in parallel.
Example:
If there are 10 items, and 2 materials, the items will be grouped into 2, and two group of items will be processed in parallel, reducing the processing time by half.
I need to know, which concept to use for the parallel processing?
Call FM in Separate Task / Call FM in Background Task or is there any other way to aceive it?
What is the maximum number of parallel/background sessions supported by SAP?
I also got some code samples:
[Starting New Task|http://wiki.sdn.sap.com/wiki/display/ABAP/Parallel+Processing]
[In Background Task|http://wiki.sdn.sap.com/wiki/display/Snippets/ABAPparallelprocessingusingRFC]

Background Job not Printing TOs immediately

Hello experts,
I am having an issue with printing Transfer Orders created by background job, the output requests are sent to the output controller with status '-' . It works when I manually create the TOs or if I run the RLAUTA10 program with my userID in SE38 .
I have set the background job user default print parameters in SU3 to print immediately.
Also in the Job step, I have set up the print parameters to 'print immediately'
I have assigned printer for sorce storage type & set the indicator to use the source sto type in OMLV, The printer seems to be determined correctly, I've checked the Spool request name & printer in the spool controller, only issue seems to be the print not being triggered immediately.
Not sure, if there is some other setting that I have to make to be able to print the TOs created by the background job immediately.
Any help would be appreciated.
Thanks
Kris T

whether the printer which you assigned is configured in SAP (network printer)? or LOCL?
printing may not happen if LOCL(background job)
Thanks

Background job SWFSLSDLEX cannot be scheduled (error )"

Hi All ,
i got the following error ,
when i try to customize the SWU3 " Schedule background job for dead line monitoring ".
The error is :
"Work item -: Background job SWFSLSDLEX cannot be scheduled (error )"
And the Error log says :
Refer to your workflow system administrator.
The specified error number should indicate possible reasons for the error. It is possible that the system is in an inconsistent state. The scheduled start of the specified background job must be compared with the minimum date/time of all work items in table SWWDHMIN. It may be necessary to delete the scheduled background job by hand and reschedule it by calling report RSWWDHEX.
Apparently i dont see any table SWWDHMIN.
Thanks!
Richard A

The issue is solved by adding start profile and instance profile to operation modes.
Many thanks to my BASIS Guys for solving it !

Parallel Processing: Error message 00-250: "No CUA area available"

Dear colleagues,
I have implemented a parallel processing with asynchronous RFC for a large data analysis in CO-PC. I think I was able to implement everything properly as described in the sap help: http://help.sap.com/saphelp_nw04/helpdata/en/22/0425c6488911d189490000e829fbbd/content.htm
But now I face one problem: My jobs are often cancelled with the error message 250 of class 00 "No CUA area available".
I don't have a clue what this error message means. I couldn't find any help in the SDN, OSS or in the internet. Has anybody an idea how to handle this problem?
Thx very much for your help!
Marius

In your program while you doing the CALL FUNCTION - STARTING NEW TASK, did you check how many work processors are available.
Suppose you have 40K data in your internal table, and in one step you are passing 4 K data. Then 10 work processes are required. But in your group setting if you have define 9, then last one will fail. So before any 'submit job in new task' or any 'CALL FUNCTION - STARTING NEW TASK' statement if have to check if any work processes are available. if available then submit otherwise wait.
Thanks
