A non-stop background process

We want to build a non-stop background process under SGI IRIX OS environment,
which can access Oracle DB and transmits large volume data files to other machine.
so, we just want to know whether we can build such a program using Java language.
and also, if we can, will it impact other system processes and resources???

Yes you can. As for the impact it depends on how are you going to build the application.

Crash on quit due to background processes

Please help, I have a deadline soon. FCPx is crashing every time I quit. It hangs on stopping background processes when I can not see that there are any, and I have them turned off.
I have done a safe boot, wiped preference, and even created a completely new user on the mac. Nothing helps. Any suggestions would be greatly appreciated.

Thank you everyone for your comments and help. We had to push the release back two weeks for many reasons, some of them this issue.
But I thought my solution would be good to know for people. For the record I was attempting to edit at 4k with imported RED files converted to optimized media. What I didn't realize is that some of those clips were actually shot at 5 or 6k. I think that was one problem in and of itself, so I converted my projects to 1080p. Still got memory errors though.
So I think what solved the issue was when I flushed the cache by moving it outside the library. I think FCP had crashed while doing background renders from choking on some of the odd clips. I believe that corrupted some of the cache system, and wasn't fixed even when regenerating the cache files.
So I went to project settings and set the project cache to be outside of my project file in a folder I created. When doing so you are prompted to decide whether or not to move your current cache. I didn't, and this forced it to re-reender all those clips (but not the original optimized or proxy media). This seemed to clear up every problem I was having with Final Cut Running Out of Memory problems. I bet it was the cache, but could have been related to the mixed resolutions.
So I thought this might helpful to others searching this forum, and thanks again for everyone's help!

When connecting Apple devices to your iPhones wireless hotspot do those devices stop background data processes to conserve data?

When connecting Apple devices to your iPhones wireless hotspot do those devices stop background data processes to conserve data?
In other words if you have a limited data plan on your iPhone will your other Apple devices such as an iPad automatically cease background data transfers to conserve data usage?

Nice trick to connect your Apple Devices to your wireless network.
Will help the users if they are facing the problem with the apple devices.

Why may any user leave background processes running at will?

Hi all,
yesterday, I encountered a rather strange problem with linux in common, at least
I think so.
In my .xinitrc, I'm starting offlineimap - a console-based mail synchronization
tool - in the background. Being naive, I expected it to be killed along with the
gui applications started in that file. Yet, that assumption proved wrong and I
started asking for help on how to kill that process on #archlinux.
The guys there (again, thanks for your help and patience!) all came up with
plenty of ideas on how to avoid starting more than once instance of the program,
but that wasn't really what I was looking for. The only usable option came from
anrxc, who suggested killing the program from awesome's logout hooks.
Not fully satisfied with the solutions, I started thinking and came up with the
following question:
Why is every user allowed to leave background processes on the machine
just as he pleases, even if he logs out?
I even tried this over ssh, where the launched commands have some sort of
"parent" process, but even in this circumstance it was possbible to leave
background processes behind after logging out.
I mean, on my desktop system, this is not a big issue... I shut it down once
every day at the least and there are no users on it besides my girlfriend and
me. But this seems like a fundamental problem to me. Why is this allowed at all?
Does it make sense to do it that way? What are the consequences?
Let's discuss!

JohannesSM64 wrote:Really, you need to find a better way to manage offlineimap than starting it in xinitrc. Automatically killing any background processes on any logout will not make linux better.
Hmm... to me, .xinitrc is the place to start apps which should live just as long
as the graphical user login lasts. On #archlinux, several other places were
discussed, but none of them were "the thing":
.bashrc
Doesn't work, because a) the process would only get started when I open a shell,
not when I log in and b) because finding a place to stop the process would be
even harder.
.bash-profile
Only gets executed for a login shell, which I wouldn't account for a graphical
login at all.
wm startup script (in this case awesome's rc.lua)
Possbile, but not much better. Would fork the process all the same, merely
moving the problem. If X got killed, not even awesome's logout hooks would
apply.
Also, this approach isn't wm-agnostic, so trying out / switching to another wm
would have the problem occur all over again.
So what do you suggest? Do you have a good idea?

As to the question of "why" things act this way:
I believe this is linux display it's heritage as a mulit-user operating system that people used terminals to log into to run program on. A big place where unix used to be (and is, to some degree, still used) was in universities where a professor or graduate student might have logged onto the system to run some program to process some large set of data. You wouldn't want to sit around and wait for this program to finish; you'd want to run it in the background, leave, and come back and look at the results a week later, when the program finished running. One of my friends doing applied math research still does this sort of thing. I'd imagine it's relatively common.
Process management was largely handled be systems administrators, and commonly you were being billed for CPU time, so it was in your interest not to leave programs that you didn't want to run running when you logged out.
Hmmm... that seems like a rational explanation. But in the case that is the
reason for linux' behavior: Why isn't there some kind of a mode setting? Like
one which allows any user to keep processes alive and another one that doesn't?

How to stop the process chain showing status as yellow but no process step

Dear Friends,
How to stop the process chain showing status as yellow but no process step is running in that process chain.
We have manually triggered the process chain for sales it finished successfully till load data but the next step is create index and DB statistics. Both of this steps are in unscheduled position only and no background job for this.
Please guide me.
Thanking you in advance.

Hi,
At times even I have faced this situation. During those times, running the Function module RSPC_PROCESS_FINISH by passing the right parameters came to my rescue.

Stop Background Image in Table from Repeating

Since CS4 has unfortunately removed the button for Background Image for tables, I found a neat work-around on the internet: select the cell, then open the Tag Inspector panel, select the Attributes button and Show list view, and click inside "background" and use the folder icon to navigate to the background image. However, I can't stop the image from repeating. I've tried everything I can think of. Can anyone help me? No code responses, please. Thanks!

monelleny wrote:

Yes.
No code responses, please. Thanks!
Well, in that case, the answer is no.
Quite honestly, if you're capable of searching for an answer on the internet, and using the Tag Inspector to add a background image, you should be capable of following simple instructions to handle CSS.
To add a non-repeating background image to a table cell (or any element, for that matter), you use CSS. Create a CSS class like this in the head of the page:
<style type="text/css">
.background {
background-image: url(images/bg.jpg);
background-repeat: no-repeat;
</style>
Select the table cell, and then choose background from the Class menu in the Property inspector.

Background Process doesn't work

Hi Everybody,
i want to change some data on a database table through a background process but the data will not be changed:
I am working on IDES ECC 6.0 (2005)
                CALL FUNCTION 'MY_BACKGROUNDD_PROCESS'
                  IN BACKGROUND TASK AS SEPARATE UNIT DESTINATION 'NONE'
                  EXPORTING
                CALL FUNCTION 'START_OF_BACKGROUNDTASK'
                     EXPORTING
                          STARTDATE = SY-DATUM
                          STARTTIME = l_time
                     EXCEPTIONS
                          OTHERS    = 1.
                IF sy-subrc = 0.
                  COMMIT WORK.
                ENDIF.
If i call the function without: " IN BACKGROUND TASK AS SEPARATE UNIT DESTINATION 'NONE' " it works fine.
What could be the problem?
regards,
Sid

Hi Julius,
i am new to abap so i am trying to find a solution in SDN. I try it also without 'IN A SEPERATE UNIT' but without success. Is it necessary to call the function: 'START_OF_BACKGROUNDTASK' after it?
                CALL FUNCTION 'MY_BACKGROUND_PROCESS'
                  IN BACKGROUND TASK DESTINATION 'NONE'
                  EXPORTING
Could you please give me an example how i can call my fuction 'MY_BACKGROUND_PROCESS' as a background task?
Thanks in advance!

Curve 8520 Non-Stop Rebooting and stuck on reboot mode. HELP

My phone is on this weird state now that it freezes and nothing happens, not even the little watch comes out and so I have to reboot it. But when I do, I have to use it non stop doing whatever for about 3 hours or so, not being able to leave it alone because if I do, even for a minute it will freeze all over again and the process will start over.
But also, sometimes when I reboot it, it doesn't being to reboot. It just stays with the screen shut off and eventually the little red light would turn on and off but nothing else will happen. I left it in that state for about 10 hours and nothing.
Right now it has been frozen for almost an hour, Ive had to reboot it about 25times today and I´m beginning to give up and getting scared for my phone.
Can't anyone please help me with a solution or proposition?
Thanks in advance.

Hello AnaVS and welcome to the BlackBerry Support Community Forums.
I would suggest you reinstall your BlackBerry device software. It sounds like something is malfunction causing the rebooting.
Do you have the Desktop Software installed? If not, you can download it at www.blackberry.com/software/desktop
After it is installed, connect your BlackBerry and back up your data.
Once you have backed up, follow the steps in KB11320 to reinstall your BlackBerry device data. Once the reinstall completes, test before restoring ANY data.
If the same thing happens without any data on it, you will want to contact your mobile carrier for further investigation.

Some background processes getting killed abruptly

Hi,
We have an E-Biz database and sometimes users complaint that some of the forms/JSP pages are not working fine. When i check the alert log, i find the following error messages which are marked as non critical.

When i checked the background processes, mmon and mmnl processes were not running. When we restarted the database, everything started working fine.
this problems keep coming occasionally. Any help will be appreciated.

Dear muneer.uae,
SHUTDOWN: waiting for logins to complete.&
PMON failed to delete process, see PMON trace fileWell i think those are enough for you to understand the problem but the important thing here to diagnose is the "deadlock". First of all forget about everything and answer the question "do you know what is a deadlock?". If your answer is no, please go to the http://tahiti.oracle.com and search for deadlock.
The problem is not the Oracle database, is the application that you are currently using. You have nothing to do about the suicide of the PMON and if you can not solve it by your own than you need to create an SR call.
Background processes "normally" do not kill theirselves.

Acrobat Mac OS background process saps CPU

I have had a background process on my Mac OS (Mountain Lion and Mavericks) that occassionally shows up. I find it via Apple's Activity Monitor and see it on the CPU tab, and sorted by CPU Time it shows up near the top.
I think it has more to do with Acrobat Pro X (maybe 9 as well), since I haven't seen it while just using Acrobat Pro XI (yet!).
Anyway, the process is called "Acrobat and Adobe Reader" in the listing, with an icon that looks like the Adobe Acrobat updater, the one with the rotating arrow on it. This process will start up at some point, and then it will never quit on its own.
While it runs, it uses up immense amounts of CPU cycles (in the CPU histogram it is the red area that grows higher than 60% of the activity), and consequently other operations get starved, and it makes the CPU run harder and hotter.
The only way I have been able to get it to stop is to select it in the Processes list and call it to quit.
Anyone else run into this? Is there any way to keep it from coming up?
Thank!

Hi pathblaster,
Please refer the following KB to diable autoupdater for Acrobat : http://helpx.adobe.com/acrobat/kb/disable-automatic-updates-acrobat-reader.html
Alternatively you can install the updates manually from : http://www.adobe.com/support/downloads/product.jsp?product=1&platform=Macintosh

Why is iPhoto doing this none stop?

My iPhoto does this none stop.
I've restarted.
I've restarted the computer, deleted the plist file and it still does it none stop no matter how long I leave it open.
Is there a quick fix. It started this after I created another library.

Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

BDC (Background processing in call transaction )

Frnds how to go for background processing in " call transaction method"
We know that " NO display" mode is there but any other method is there in real time.
> in session method while data is getting uploaded suddenly server stops then how to upload the data from the last record where the server stopped.
plz help.
regards,
satya

Hi
u have to use No Display mode in call transaction...there is no other go for this...
Otherwise opt for session method and using SUBMIT rstbdcsub. process in background.
When server stops mean while the processing of the session, u can get the processed records info by the log and you can process the failed / un processed records now by foreground in sm35 or u can process the entire file again or u can create the file with only failed records and process .

Using 'export to database' in background processing

If i call a Function Module in Background will i be able to Export values to Database ?
like:
CALL FUNCTION 'func_name' IN BACKGROUND TASK TABLES table = table1.
and in FM:
EXPORT <one> FROM <two> TO DATABASE indx(some) ID 'some1'.
I am only able to export if i dont use the background processing.
thanks
Edited by: shalaxy s on Feb 10, 2009 3:18 PM

Hi Shalaxy,
Calling Function Module in Background/Update Task is normally used for bundling techniques where your requirement is to execute all the database updates in single database LUW (Logical Unit of Work) in order to maintain data integrity. All your database updates gets successfull or none of them.
If you call FM in Background Task, it is not executed immediatly, it is registered with all its values and executed only when COMMIT WORK statement is executed.
I think there is no explicit COMMIT WORK statement in your code and that is why you are not able to see effect of EXPORT TO DATABASE statement as LUW is not at all initiated.
I feel, as your requirement is only to suppress the ALV output, you should handle it through some other alternative e.g. using parameter or something like that and If function module you are talking about is Z and you are willing to change it.

Vishal

RAC instance won't start: ORA-00443: background process "VKRM" did not star

I've logged a SR with Oracle, but while waiting for response from them...I'm stumped I can't find more out here about this article.
On Oracle knowledgebase...any search for VKRM, gives about the same 3 articles relating to RDA (Remote Diagnostic Assistant).
Not sure what went on here.
I have a 5 node RAC cluster. All other instances seem to be running just fine.
On one instance...some applications were getting an error like:
ORA-01033: ORACLE initialization or shutdown in progress
I looked in GRID...and it indicated that only two of the 5 nodes had this instance running...which was strange in that with srvctl, it showed ll 5 up and running:
[oracle@server2 bin]$ ./srvctl status database -d INSTANCE
Instance INSTANCE1 is running on node server1
Instance INSTANCE2 is running on node server2
Instance INSTANCE3 is running on node server3
Instance INSTNANCE4 is running on node server4
Instance INSTANCE5 is running on node server5
Anyway, thought I'd poke around. I started with trying to get srvctl to stop instance #2...in GRID it seemed that instance 2,4 and 5 weren't working.
srvctl stop instance -D INSTANCE -i INSTANCE2
This just hung...
I thought I'd cycle all the nodes...so, did a ctl-c out of that one, and did:
[oracle@server2 bin]$ ./srvctl stop database -d INSTANCE -o abort
PRCD-1124 : Failed to stop database INSTANCE and its services

I get similar messages when I try to restart.
clusters seem to be up, and other instances seem to be ok
Looking at alert log...I found some strangeness in the traces

Anyone? Anyone? Bueller?
Ok..have been on phone with Oracle support, and have them stumped so far.
I've checked..other instances are running (except one other that failed to cleanly shut down with srvctl and same error messages).
I've check...ASM is running on all 5 nodes. I've used crsctl to check CRS on all nodes..clustering seems ok.
Memory while somewhat high...should have enough room...the system has never complained before, and this has been up on this config for over a year.
I was able on node one...to fire up the first nodes instance using the pfile there...it came up. I started it restrict..and promptly ran a datapump export, and then shut back down.
While Oracle support is going through logs and trace files I sent...I've got another 11Gr2 environment (3 node RAC) I've been using as a test environment...and am recreated the instance there temporarily to allow my developers to test and get past the upcoming deadline.
But, I'm still puzzled as to the solution on the main cluster. This seem to be normal, except these two instances....
any ideas on where and what to look for?

Servlet background process on tomcat 4.0.2

i have 1 servlet which will run a thread, background process, whenever the init() on that servlet called. i tried on tomcat 3.3a and tomcat 3.2.3, and both tomcat will run my servlet's background process, will run the thread. but, when i run the servlet using tomcat 4, tomcat 4 will run the init(), but when it do not start the thread. what happen?... i used the same code, servlet, on tomcat 3.2.3, 3.3a and 4....
can anyone explain it to me?.....

my code look like this:
public class Discover extends HttpServlet implements Runnable
Thread t = null;
boolean running = false;
public void init()
t = new Thread(this);
t.start();
System.out.println("thread start");
public void doPost(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("discover=" + running);
public void run()
running = true;
System.out.println("thread running...");
* do some stuff here....
running = false;
System.out.println("thread stopped...");
i tried this servlet on tomcat 3.2.3 and 3.3a and the thread run. i can see the 'thread start', 'thread running' and 'thread stopped' on the tomcat console. but, when i use tomcat 4, i can only see 'thread start' on the console, which show that the run() is not execute...... y?... please help me.......
