Run Servlet in the background (Daemon)

Hi all ,
I am using Apache Tomcat/5.0.25 container.
Need some advice regarding running servlet at the background or as daemon . Below is the scope of the program :
The servlet will do a updating in the database in the background every 5 minute.
Any ideas how to implement such behaviour using servlet ?
Thanks.
Wee Tat

hi..
Make a thread and initialize in the init method of ur servlet.
And make another thread so that it wakes up every five minutes and does the database processing..
so ur servlet always has a thread which invokes the other thread(database accesing thread)..
here is the code sample ..
Thread t = new Thread( new Runnable() {
public void run() {
Thread dbHandler = new DBHAndler(..);
dbHandler .start();
try {
t.start();
catch(IllegalThreadStateException e) { }
hopefully it works..
regards
Kovi

How to run form in the background from command line

how to run form in the background from command line

Ummm....Oracle Forms is a foreground runtime kind of thing. What you want is a database procedure (or an OS utility - it depends on what sort of processing you want to do in the background).

You can always shut it down manually via the Task Manager

Running AppleScript in the background

Okay, yet another problem I'm having that I'm going to bug the community here with.
Is it at all possible to run AppleScript while doing other things? For example, if I wanted my AppleScript to hop online every hour and send me back information from my site could I have it do this while I do other things? Or will I have to wait until it's completed?
Say I wanted to create a script that hopped on my site and sent me the post number of the last post, could I have it do this while I do other things?
Something like
tell application "Safari" to activate
tell application "System events"
tell process "Safari"
(enter code here to get post number and send it to me)
end tell
end tell
I've tried doing it like this and it definitely doesn't work at all if I don't have the Safari window selected at all times, so is there any way in which I can run script in the background while I work on other things or does AppleScript require full control of my computer while it's working?

Save this script just like the others I posted. The script will do exactly as you asked.
<pre style="width:630px;height:auto;overflow-x:auto;overflow-y:hidden;"
title="Copy this code and paste it into your Script Editor application.">property helloWorld : "Hello World "
global numChars, charNum, x
on run
tell application "System Events" to set isRunning to exists process "TextEdit"
if not isRunning then tell application "TextEdit" to launch
tell application "TextEdit"
if isRunning then make new document
set name of window 1 to "Hello World"
set numChars to number of characters in helloWorld
set charNum to 0
set x to 0
end tell
end run
on idle
try
tell application "TextEdit"
if x = numChars then
set x to 1
else
set x to x + 1
end if
set charNum to charNum + 1
set theChar to character x of helloWorld
set character charNum of document 1 to theChar
end tell
on error
quit
end try
return 0.1
end idle
on quit
continue quit
end quit</pre>

Running program in the background

Hi everybody!
I need to run program in the background.
So I need only to change the sy-batch status to 'X'?

HI,
if your program is runninn in the Background then the System field SY-BATCH will become 'X' otherwise it will have space ......
it will not execute the job in the background if you put SY-BATCH = 'X'
you need to use: Job_open , Job_submit and job_close function modules
example:
*Submit report as job(i.e. in background)
data: jobname like tbtcjob-jobname value
                             ' TRANSFER TRANSLATION'.
data: jobcount like tbtcjob-jobcount,
      host like msxxlist-host.
data: begin of starttime.
        include structure tbtcstrt.
data: end of starttime.
data: starttimeimmediate like btch0000-char1.
Job open
call function 'JOB_OPEN'
       exporting
            delanfrep        = ' '
            jobgroup         = ' '

                number jobcount.

How to run long running report in the background

Oracle Application server 10g
I need to run the long running reports in the background because while the report is running the cursor is loading and the control doesn't return to the user
this feature exist in oracle 6i by set the following parameter
RUN_PRODUCT( REPORTS, 'r_1', ASYNCHRONOUS, RUNTIME, FILESYSTEM, pl_id, NULL);
How can I accomplish the same in OAS 10g?

Hi,
I've done this in 11g. I think it will be the same in 10g as well
Following are the steps in 11g using run_report_object.
1. Read metalink note: Using the Reports Server Queue PL/SQL Table and API - RW_SERVER_JOB_QUEUE [ID 72531.1]
2. Implement RW_SERVER_JOB_QUEUE table as per above notes.
3. When submitting report run it as background
a. SET_REPORT_OBJECT_PROPERTY(lo_report_object, REPORT_EXECUTION_MODE, ASYNCHRONOUS); -
SET_REPORT_OBJECT_PROPERTY(lo_report_object, REPORT_COMM_MODE , BATCH);
4. Display the job_id to user (notification).
5. Create a new form to view reports base on on RW_SERVER_JOB_QUEUE which provides you the status, etc.... (you may have to create a way to identify the username who submitted the job. This way not all users will see the jobs in RW_SERVER_JOB_QUEUE )
6. Optionally you can use NOTIFYSUCCESS=email to notify user when the report is finished.
Cheers

Run OC4J in the background

Is there anyway I can run OC4J in the background as an NT service?
Thanks in advance.

I took the approach above, and my experience was only partially successful. With some scrounging around newsgroups, orionsupport.com, and Sun's website, I came up with the following solution:
Creating an NT Service for OC4J
OC4J by default runs as a command shell application, so it is bound to a user's login session and will die if the user who called the start command logs off of the system. Oracle has not provided a version of OC4J that runs as a service on Windows-based servers, so here is a process to create a service using the freeware utility, RunExeSvc (http://www.winwinsoft.com/goodies/RunExeSvc/index.html). This utility is more user-friendly and flexible than tools such as srvany.exe and instsrv.exe in the NT Resource Kit.
Dependencies
1. RunExeSvc is installed
(Unzip the runexesvc.zip file to a directory)
2. Sun's JDK 1.3.1 is installed.
(JDK 1.3.1 is required because a bug in prior versions of Sun's JVM for Windows killed any JVMs initiated by a user in that login session.)
Installation Procedure
1. Run the RunExeSvcAdmin.exe application
2. Create a new service by copying the example script below into the Script window of RunExeSvcAdmin.exe. Some changes to drives and/or paths may of course be needed.
3. Save the new entry and exit the application.
4. The service should now appear in the services control panel. Changes may be required for its startup options.
Example Script#########################
# This script runs OC4J
# RunExeSvc variables
# if true, RunExeSvc will show internal status
debug=false
# the starting dir of the service
home=e:\oc4j\j2ee\home
# Running as an http server.
cmdline=e:\jdk1.3.1\bin\javaw.exe -Xrs -jar orion.jar -out e:\oc4j_out.log -err e:\oc4j_err.log
null

How run OC4J in the background

Hello!
How can I run oc4j in the background(without a window open) on a solaris box?
I have tried 'nohup java -jar oc4j.jar &' but the startup seems to hang when I do this.
Any ideas?

Make sure you can write to nohup.out in the current directory.
Also, I typically start my OC4J in /etc/init.d from my solaris machine and that seems to work nicely.
Also try putting the 2>&1 at the end instead of in the middle.
Of you could try using CSH vs. SH, some google hits mention that makes life easier.

Problem in running servlets over the net & in non-root user mode(FC-4)

I have installed Tomcat 5.0.28 and it is running

onto non-root user, when i call the servlet through the

I thank in advance if any could help me in this case

Did you try using %20 instead of a space? I know it works for URLs...worth a shot.

Running Skype in the background on iPhone 3Gs

I was under the impression that the 3Gs could run more than one application at one time. I am trying to figure out how to start Skype and just leave it running as long as I am online (wifi, of course, I understand that Skype won't work over 3G). I want to be able to answer calls via Skype and not have to leave my iphone on Skype all the time.
Anyone know how to do this?
(I was really, really disappointed to learn that the iPhone/ATT deal doesn't include an app that allows me to automatically switch from 3G calls to WiFi when I get into WiFi range. My Blackberry did this without as much as a thought...totally automatic... Anytime I was near a WiFi network, anyone who called my cell phone number would be connected to me via VOIP. I'm really bummed the iPhone doesn't do this. )

What I'm trying to accomplish is to have an app which will accept VOIP calls open and running at all times so that I don't use cell phone minutes while I'm on WiFi. That was the joy of the Blackberry (also ATT): Whenever I was on Wifi, anyone who phoned my normal cell phone number was automatically routed through Wifi and connected to my blackberry, just like a normal cell voice call...but it was using VOIP and I didn't have to use my cell minutes. I was completely dumfounded to learn that this wasn't standard operating procedure for the iPhone. So I figured, OK, the next best thing would be to have the iPhone have Skype running in the background so folks could at LEAST contact me that way without it using my cell minutes.
So far, not so impressed with way ATT and Apple have this arrangement going. I hope I can find some Apps for the iPhone that impress me perhaps that will help redeam the (pretty lacking) VOIP integration that I've seen so far.
But I totally admit: I'm new at the iphone (Apple user since 84) and I may yet become convinced that this is a decent product.... Week 1 with the 3Gs, pretty disappointing.

Running xscreensaver in the background after resume from hibernate

I'm using hibernate-script with my tuxonice kernel. One of the things that annoys me about xscreensaver is how when I resume its always running (because the requisite time has passed), so I have to type my password again, having just typed it at BIOS level.
So I killall xscreensaver in an OnSuspend in /etc/hibernate/common.conf. However, restarting xscreensaver doesn't go to the background. What I'm using is this:-
OnResume 20 sudo -b -u MYUSERNAME /usr/bin/xscreensaver
However the terminal that I typed sudo hibernate from never returns, I have to killall xscreensaver from another terminal to get it to release. The problem does not occur when I login to a vt as root and run the same command.
Any suggestions?

I just registered for the forum so I could toss in my solution, so I hope this is what you're looking for. I fork the process and use the 'disown' command. I also use Dan Bernstein's 'setuidgid' utility because I couldn't get it to work with su (I didn't try very hard):
OnResume 70 setuidgid USERNAME xscreensaver > /dev/null 2>&1 & disown
This works for me even if I execute hibernate and resume from a terminal, despite the fact that II get a "can't find display" error from the terminal.
Of course, the stdout and stderr redirect to /dev/null is not necessary. The 'disown' command removes the subprocess from the process table, so that the subprocess is no longer a child of the parent. It is cast off, essentially. I also use a similar command for restarting gkrellm because gkrellm sometimes fails to recognize my second battery after resume.
One quirk I have found is that hibernate will halt if a kill or killall fails. I thought this was happening because the kill command had returned a non-zero exit status. But I just discovered that forking a kill command prevents hibernate from halting when a kill fails, as in:
OnSuspend 20 killall xscreensaver > /dev/null 2>&1 &

Running actions in the background

Hello All!
I'm a wedding photographer using CS5 on a Mac Pro. I run an action to re-size 800-1000 photos. After running the action I continue to work on other projects; i.e.; check e-mail, surf the net, lightroom, etc. Although the windows for these application fills my monitor, the photos in CS5 continue running in the foreground. It's impossible to do anything else because CS5 keeps popping up in front of any application I use. How do I run the actions in the background?
Thanks
Chris

That's interesting... I'm thinking it must be an OS thing, given Photoshop's implementation...
I say that, because just yesterday I was, on my Windows 7 workstation, running the Image Processor script to open a document, do an action, resize, and save - all this on a whole folder full of documents. Photoshop got to chunking away and I just made some other apps current and began work on eMail, web browsing, et. al.
Photoshop just stayed behind everything and worked away. I could see it working if my current window didn't cover everything, but at no time did it jump in front of what I was doing. I didn't use PhotoJunction, though - I have no idea what that is.
I'm not trying to start a PC vs. Mac thing here, but just pointing out that on the PC side multitasking while Photoshop's cranking doesn't seem to be as big a deal.

Running Apps in the Background 2.1?

Now that 2.1 is out can anybody confirm that the you can now run 3rd party Apps in the background? They mentioned that ability back when they introduced the iPhone 3G but I haven't heard any talk about it recently with this update. Anybody able to install the update and confirm or deny this?

They must have. No apps have been able to run in the background even on 1g iphone. Maybe because Apple realize that the battery wouldn't last 2 hours with apps running in the background.

Running VI in the background

I want to run a VI in the background that performs the acquisition from a Field Point from time to time, and keep my interface VI unlocked for the user while the data acquisition is being done. Anyone knows how to do that?? Thanks!!!

Hello:
You can certainly do this using LabVIEW. You just need to program your LabVIEW VI to read from your FP module at the desired loop rate and update a front panel or whatever you want to do there. Another good solution could be to use LabVIEW Remote Panels to have a system acquiring data from the Fieldpoint module that you can access over the Internet using your web browser from any networked PC. You can find more info on Remote Panels (LV versions 6.1 and later only) in the LabVIEW help or online at http://zone.ni.com/devzone/learningcenter.nsf/03f7c60f17aad210862567a90054a26c/2ad405a06ebed71586256c4e00621c73?OpenDocument.
Good Luck!
