Sy-batch value when debuggin a background process

Hello All,
I have a quick question. I am working with a background job and I have a doubt about the sy-batch value. I know it set to 1 when the process in run in background but if I turn the debuggin on [ via the infinite loop ] then will the sy-batch value change to SPACE ?
In debugging I see its changed to space but I am wondering is it cause I am debuggin in background or is it because Its an update task ?
can you please advise ?
thanks,

The SY-BATCH should come as "X" when you debug a background job via infinite loop. Have you called any code update task? If yes then it will be processed via dialog processing so here SY-BATCH will be initial.
I just set this program in background and found that the SY-BATCH as "X" and it goes to infinite loop.
REPORT ztest1.
DATA: l_flag TYPE c LENGTH 1.
DO.
IF l_flag = sy-batch.
    EXIT.
ENDIF.
ENDDO.
DATA: l_string TYPE string,
      l_final TYPE string.
l_string = 'UPS Surface Collect #954365'.
DATA: l_dummy1 TYPE string,
      l_dummy2 TYPE string.
SPLIT l_string AT ' #' INTO l_dummy1 l_dummy2.
CONCATENATE l_dummy1 l_dummy2 INTO l_final.
WRITE:/1 l_final.

Can I get some help as to why is it not able to loacte the file when run through background processing when its able to read and excute when I directly run the program. Is theer any settings that I need to set up in the ABAP program itself which will enable to make it happen or else what to do so that I can set a background job to happen successfully.
Thanks

Compressor 2 and FCP 4.5 "background process" error

So I switched to my laptop which is running 10.4.11 and Compressor 2. I get "Cannot submit batch" Unable to connect to background process. I don't know if I should try the same proposed solutions that are suggested for the newer versions of the software? Any other suggestions?

VAR,
1. When you can spare another 5 min to solve your problem, instead of coming here and complaining about no one helped you (though Tom did offer a very direct response) you might take the time to read your DVDSP manual.
In it, you will discover that DVDSP is totally capable of converting quicktime movies to m2v and aif files. You have full control over all aspects of bitrate etc. Indeed, it is the same engine as in compressor. If you need an AC3 file, use A-Pack on the aif DVDSP will create.
2. When you say compressor does not work, do you mean -A. it does not launch from within FCP or B. you can not launch it independently?
If it will launch independantly. export a reference QT file, open Compressor and have at it.
QT7 is a problematic issue with FCP4.5. The long term solution is to upgrade to FCP5 to go with 10.4 and QT7. They all fit together much more neatly.
fwiw -
1. the people who hang out here and help out fellow users are not employees of Apple. If you want to complain about the software, a good place to do it is on the FCP feedback page This forum is to provide technical support.
2. The people who hang out here and help fellow users are not compensated. Their efforts are volunteer and no one is under any obligation to respond to you in any way. If you don't like the advice, I'm sure Apple techincal support would be glad to have a $199 conversation with you.
3. Tom is a mainstay of the board and one of the the most knowledgeable people you will find regarding FCP. As such he is highly respected by the serious users of the forum. You will not find a great deal of sympathy or support here if you continue on in this vein ..
You have a technical issue, post the details, For example, what have you tried to solve the problem? The intellectual resources here are quite amazing. I've not seem many posts go unresolved for lack of trying.
good luck.

Measure optimal values of background processes (RMON,PMON,RECO)?

Hi buddy's,
I am facing issue to determin optimal values of oracle EBS R12 background processes like (RMON,PMON,SMON,RECO)?
I want to determine and find it's maximum optimal values of each process with step by step guide because i am new in oracle.
My purpose is that if i found the optimal values of all background process then while during tuning it is clear for me to what i want to achieve.
Kindly help me and clarify this scenario how is it possible ?
Best Regards,
Waqar Arif

Hi,
You should learn some concepts first because you seem very very very new. RMON,PMON,SMON,RECO are background processes of Oracle database and there isn't anything called "value" associated with them. you can't control them or set any value for them. These are background processed which will rung when your instance will start.
See bellow for some concepts

When running the workflow background process for drop shipment order, sale order line's status gets automtically closed instead of awaiting shipping

Hello friends,
I am created a drop shipment order with all the setups done . now i have booked the sale order as source type external. but when i run the workflow background process , after completing the report when i check the sale order line status it changes to "closed" instead of "awaiting shipping".
Plz guide me if i have missed something in the setups.
thanks,
Sachin

Hi Sachin,
pls check the below notes from MOS

1. Use BADI: WORKORDER_UPDATE--> Method: BEFORE_UPDATE
2. Use ASSIGN "(SAPLCOBT)AFPO_BT[]" statement to access and modify the desired fields.

Parallel Processing when running in background

Hi
We have implemented a parallel processing solution using the Call Function Starting New Task Destination in Group format to split a large number of updates across an RFC Server Group.
This works well when running the ABAP in dialog, but when we schedule for background processing, the parallel processing does not seem to occur, we get a single background process.
Does anyone have any ideas why this may be occuring ?
Thanks
Paul

Paul,
Starting new task will start a new LUW in dialog process and not in background. This is the reason you are having a problem. While technically STARTING NEW TASK is used for parallel processing, you need to consider whether the program will be run in foreground or background mode.
In case of background, you need consider using multiple jobs via job open, submit, job close. This way you can initiate more than one process in your server group to do the work.
You will need to consider the # of background WP available and the # of WPs you can use for this program.
So if there are 100 WPs available and you can use only 10 at any give time, then you should schedule 10 jobs and then check the status of the 10 jobs before you can start scheduling the next jobs.
You can use the FM SPBT_INITIALIZE to check the # of WPs that are currently available in the server group.
Hope this helps.
Thanks,
Vikram.M

Connot submit batch - Unable to connect background process?

Trying to export 60 min high quality mpeg and get the following message: "Connot submit batch - Unable to connect background process"
I use FCP 4.5 HD

You don't give many details but Jon Chappell of DigitalRebellion has produced a free utility to help with Compressor problems.
He posted these details recently:-
"It seems like a number of people on this forum are having problems submitting batches from Compressor, so I created a utility to diagnose and fix some of those problems.
Compressor Repair will check all necessary files exist on your hard drive and that permissions are set correctly. It also resets Qmaster, trashes the Qmaster spool directory and launches qmasterd."

Front Row launches as background process when running second display

When I connect a second display, Front Row launches as a background process and hogs upwards of 90% of my CPU cycles. I've tried connecting things in various orders, but had no success in avoiding this.

try restarting and it will works. it happens to me some of the times or unplug your cable and plug it in again.

When will Apple allow background processes for the iPhone?

Can't find a suitable subforum so I'll post it here, please refer me to the correct Apple forum otherwise.
When will Apple allow background processes for the iPhone?
When will Apple allow Alerts from 3rd party apps?
Even my first Palm Pilot allowed developers to use Alert beeps.
Why is Apple crippling the iPhone?
If they continue this, Android will be the winner.
Or will the next SDK allow this?

Background processing, simply won't. They already said they won't and explained why.
However, they are currently adding "Push" ability to developers (soon). Originally they did say they were shooting for Sept (but obviously that has passed). Nobody can say "why" it is late or when it will come. Just know it is coming.
Push in case you don't know will let a service (one service) run in the background that apple makes for the phone. that service will ping apple's servers. Apps that want to "run" in the background have to register with that service thus lets say AIM is on your phone, you send a message and close...somebody responds. AIM's servers will send notification to the push service...then the phone will alert you of a notification in the AIM app, you open (thus starts the app again) and it gets the message.

Background Processing, Selection Screens and Variants

Hi All,
I am having a little trouble Background Processing with Selection Screens and Variants.
When a user runs my report and selects the option of background processing, then they select a checkbox.

Reducing Windows Background Processes

I'm in charge of my company's data acquisition system and we've finally got everything running about how we want it to. The last issue we're having is that whenever the screen updates the program slows down measureably. I've got the program running in a loop that collects data, processes data, waits for user input, sends out commands to other hardware, and then repeats. The program is configured to only display one data point (64 channels, plus 5 on a chart and three other numeric gauge indicators) of every 100 collected. The effect this has is that while the program is not displaying data the loop executes in about 2-3ms, but that time jumps to ~60ms when it has to update the front panel.
My question is: how can improve the performance of my code on a windows XP system?
Is there some kind of indicator that I should use over another kind?
Does anyone have a guide on how to disable windows background processes (the computer the DAQ system is on isn't running much, but I'm not a very advanced user in that area)?
Any other general tips and tricks for this kind of problem?
I know the best solution would be to move to a real time operating system, but that just isn't an option right now. Any suggestions on how to improve performance on the system I've got would be appreciated.

Some clarifications, as requested. We're acquiring 32 analog channels and 32 thermocouple channels. The gauges and chart indicators are just a way of displaying a subset of the data in a more obvious form. All channels are also displayed in numeric indicators. The program is set up to run a loop with the following DAQ scheme: calculate a timestamp (relative to the start of the program), acquire a single scan of the analog channels, acquire a single scan of the thermocouple channels, and then do other data processing tasks. There's no set data rate, we're trying to acquire the data as fast as the program will allow, so the 2-3ms loop times is what we see in the output data file. One data point will occur at time 0.003, and then next would get the timestamp 0.006.
Every time the screen is updated, in the post-processing part, the time to execute the whole loop increases dramatically. In the data file we'd see a point recorded at time 0.006, and then the next one would be at time 0.066 (something to that effect). Since screen updating seems to be the cause of the slowdown I'm interested in what I can do to get that part to run as fast as possible.
We're running LabVIEW 7.1, and to get the screen to only update occasionally I have it set to keep a counter going that is incremented each time through the loop. If the counter gets to the value of 100, then in post-processing the current batch of data is sent to the front panel indicators and the counter is reset to 0. For all other counter values the data just goes into the output file and the screen indicators are left alone.

Need to create Server group for Background processes

Hi Gurus,
I need to increase my background work process can anyone tell me how to configure it.There is only 1 background work process configured in my installation.
Thanks,
Ravi

HI Ravi
When you goto transaction rz10, you will rightly get 3 profiles,namely
Default profile
Start profile
Instance Profile
Out of the three, select the instance profile ( the one with the SID and the instance number) and get in the change mode by clicking on the spectacle button in the bar.
Further you will find the parameter rdisp/wp_no_btc in this profile. This parameter indicates the no. of background work processes set for this particular instance,
Change the value for this parameter. Also note that the no. ny which u increase the batch proceses, also reduce the dialog process by the same number in parameter rdisp/wp_no_dia.
Restart the system and the changes will come into effect.
I hope this helps you
Regards
Chen

BACKGROUND PROCESSING, REPORT NOT LOADING, "OBJECT NOT SET TO INSTANCE..."

Post Author: thecoffeemachine
CA Forum: .NET
I already posted this message in other Web sites, but I am almost getting crazy here and I need help:
HI:
The Web application I am testing was having several issues related to loading Crystal Reports. It was fixed and I do not know which of the 1000 things I did to fix it; but now it began, again, to have the same behavior after I had a conflict with another Web site that was in the same server.
The thing is that I had another virtual directory where resided a copy of the same Web app. for testing purposes/working with the Visual Studio. The reports were loading all fine, very fast, all perfect... And suddenly the assemblies of one Web site and the other began to "blend" together and..... well the same behaviors appeared again. I tried to copy the last stable backup and rebuild the Web app... but it did not work.
At the very first time that one requests the report, it shows without problem. At the second time it shows an error message related to "cannot submit to background processing", and sometimes "object not set to an instance.." ... and on the third time it just never shows up and the app. becomes unresponsive. I have to close the window and request the Web site again in another browser window. If I wish to see the report again I have to wait for hours until it shows it.
I am using Visual Studio 2003 and the Crystal Report version that was shipped with that Visual Studio version. I am working with Windows Server 2003 and SQL Server 2000. Below is the VB code:

I already have tried moving the Crystal Reports dll´s to the bin directory. ..... I have tried calling the Garbage Collector at page unload...I also have checked, inside the report, that the database is "up to date"... ... recycling the worker process of the IIS... etc...
I see that, in debbuging mode inside the Visual Studio, when the page loads the debbuging window shows a message notifying that the symbols related to the Crystal Reports dll's could not be loaded.
Should I need to modify the default properties of the database? I checked "database is case insensitive", "use indexes or server for speed".. I have tried checking and unchecking the box "performing grouping on server"
Oh by the way, my report has about 4 subreports in it. Each report loaded shows 1 or 2 pages.
ANY HELP WILL BE EXTREMELY APPRECIATED....

SAP BI 7 - Background process performance Issue

This question is about efficiency of dialog process compared to inefficiency of the background process and I want suggestions from SAP Basis/BI experts on this.
We have observed that our background processes on BI server are not running as efficiently as we would like them to run.
For example
DSO activation:
When I use Dialog mode for DSO Activation with 3 parallel processes, I can activate a certain DSO with in 15 seconds. But the same DSO and the same data package when activated using background mode with 3 parallel process takes about 15 minutes.(there are plenty of background processes available on the system when this activation is running). So dialog process runs 60 times faster than background process.
In BI 7 most of the operations can be executed only in the background parallel mode. And from the activation example we know that our background processes are not as efficient as dialog processes. It
is understood that in general the background processes will not be as efficient as dialog processes, but in our case the difference is a factor of 60. We want help to identify, why the background processes are not as efficient as dialog processes. What SAP Basis settings need to be changed to make them as efficient as we can. Any suggestion or help will be highly appreciated.

Hello Eswaran
Generally a dialog process is not faster by any means than a background workprocess. Nevertheless i trust you on your observations, so there must be some difference. I just did a small test, i ran SE16 chose a big table and selected 10000 rows, i did 3 tries in dialog and 3 in background. The results:
dialog: 10.2s, 9.4s, 9.6s
background: 26s, 24s, 24s
So even in my simple example the background execution took more time. The issue here is, that the resulting output (which is pretty large) had to be saved additionally in a spool (a total of 167 pages) when executed in background. The selection of the data certainly did not take more time in either case.
The most important difference between dialog and batch processes is the memory management. Dialog processes work with a shared memory segment (extended memory). Background processes have their private heap memory.
Nevertheless, background processes are not "slower" in general, not at all. You will need to observe closer, what your processes are doing. Maybe watching SM50 while running the DSO activation is enough to see it, maybe you need to trace a process. If you see large spools generated, or huge amounts of memory consumed, we might already have an answer.
