I dont want a server process which is a daemon to shut down - even on recieving kill signal. Is there any way to ensure this?
You can block almost all signals, with the notable exception of SIGKILL. By default the kill command sends SIGTERM, which you can block. Read about the sigaction system call to learn how to block signals.

If I issue a shut down command on Tomcat does it process all messages in progress using Spring Integration
No; when you stop Tomcat, the application context is torn down and Spring Integration doesn't have any control. We introduced a new Orderly Shutdown feature in 2.2 using a JMX operation that allows stopping all active components (pollers, JMS listener containers, etc) then waiting some time for messages to quiesce. Some endpoints (such as the http inbound) are aware of this state and won't allow new requests to come in, while staying active to handle active threads. It's not a perfect solution but it covers the vast majority of use cases.

Yes/no shut down
I have amended your code as per below: Option Explicit Dim result result = MsgBox ("Shutdown?", vbYesNo, "Yes/No Exm") Select Case result Case vbYes MsgBox("shuting down ...") Dim objShell Set objShell = WScript.CreateObject("WScript.Shell") objShell.Run "C:WINDOWSsystem32shutdown.exe -r -t 20" Case vbNo MsgBox("Ok") End Select The main issues were that "option explicit" has to be at the top, and as a result the "result" variable then must be declared using the "dim" keyword. The above code works fine when I executed it via the command line. I also added a timeout of 20, but you can easily change this back to the original value of 0.

Shut down SocketServer on SIG*
Disclaimer: I have 0, nil, null, none, no experience with python. Disclaimer 2: I, in no way, think that your server is "the way to go" when it comes to...anything server related, not even for the most basic things or anything outside school homework stuff; it might be a decent sample to help people learn the basics but it is, at the same time, misleading and wrong on so many levels I lost count.

Shut Down Web Application
You can use the appcmd command line utility for managing sites on IIS. It's located in %systemroot%system32inetsrvAPPCMD. I think it is available in IIS v7 and above only though, not sure if your using an older version of IIS. To stop and start a site, the command will look like the following: %systemroot%system32inetsrvAPPCMD stop site <Your Site's Name> %systemroot%system32inetsrvAPPCMD start site <Your Site's Name> More info on the appcmd utility is here: http://www.iis.net/learn/get-started/getting-started-with-iis/getting-started-with-appcmdexe

Does Junit shut down all the threads?
This is actually not JUnit but the external systems which run JUnit test (like Eclipse or Maven) who are responsible for terminating JVM. Those call System.exit which stops all the threads. If JUnit did it then the external system would have no chance to process the results.

How to pause windows shut-down
You need to handle the WM_QUERYENDSESSION messsage. It's sent to each application before Windows starts the shutdown process. Do what you need quickly, because failure to respond rapidly enough causes the behavior you're observing in FireFox, which is usually a sign of a badly designed app (and the user may terminate it before you get a chance to finish). interface ... type TForm1 = class(TForm) procedure WMQueryEndSession(var Msg: TWMQueryEndSession); message WM_QUERYENDSESSION; end; implementation procedure TForm1.WMQueryEndSession(var Msg: TWMQueryEndSession); begin // Do what you need to do (quickly!) before closing Msg.Result := True; end; (Just as an aside: The enabling/disabling of sounds is a per-user setting, and you should have a very good need for inter

C++ Ways to shut down a program
The if (running == 0) but is pointless! while (running == 1) { commands(); } return 0; Does exactly the same - once running is 0 it falls out the bottom of the loop, and main returns. The whole idea of the global running is getting into side effect programming, which is a bad thing!

How to stop/shut down an elasticsearch node?
Updated answer. Some options: In your terminal (dev mode basically), just type "Ctrl-C" If you started it as a daemon (-d) find the PID and kill the process: SIGTERM will shut Elasticsearch down cleanly If running as a service, run something like service elasticsearch stop. Previous answer. It's now deprecated from 1.6. Yeah. See admin cluster nodes shutdown documentation Basically: # Shutdown local node $ curl -XPOST 'http://localhost:9200/_cluster/nodes/_local/_shutdown' # Shutdown all nodes in the cluster $ curl -XPOST 'http://localhost:9200/_shutdown'

NSXML Parsing Ampersand Character Causes Shut Down
The issue is that you have not been given XML and the parser legitimately gets in a mess as it sees data that is not legal.. The XML specification says The ampersand character (&) and the left angle bracket (<) must not appear in their literal form, except when used as markup delimiters, or within a comment, a processing instruction, or a CDATA section. If they are needed elsewhere, they must be escaped using either numeric character references or the strings "&amp;" and "&lt;" respectively. Thus you have to alter the XML and replace & by &amp;

My VPS has been shut down now again for the second time for TOS violations email spam
We dealt with the same problem earlier this year. First, you need to look through your log files to determine which site(s) are getting attacked. My guess would be that the sites being hit at 1.5 sites, without exception that was the case on our servers. If that is the case, then those sites need to be let go. If they don't want to upgrade, they need to take their sites elsewhere. Simple as that. You cannot risk your other sites and email blacklists due to customers that don't want to upgrade. We don't allow J1.5 on our servers any more.

Detect Interpreter shut down in daemon thread
This is a code from threading.py module: import sys as _sys class Thread(_Verbose): def _bootstrap_inner(self): # some code # If sys.stderr is no more (most likely from interpreter # shutdown) use self._stderr. Otherwise still use sys (as in # _sys) in case sys.stderr was redefined since the creation of # self. if _sys: _sys.stderr.write("Exception in thread %s: %s " % (self.name, _format_exc())) else: # some code might be helpful. The error you see comes from else statement. So in your case: import sys as _sys while True: if not _sys: break/return/die/whatever do_something() time.sleep(interval) I'm not sure if it works though

Getting NullPointerException in Spring Batch when tomcat is shut down
I have not tried with spring quartz. However, normally while using Quartz, we shutdown the quartz gracefully. By gracefully, I mean here that I will shutdown the scheduler only after executing all my pending jobs(jobs which are executed currently but have not yet marked their completion). For graceful shutdowns, we pass attribute true while using method shutdown. Refer API here I am eager to know how spring quartz implementation does this.

Vagrant destroyed on host shut down, Windows
I'd suggest creating a project directory for each VM you plan to use. If you change into that empty project directory before doing vagrant init a dedicated Vagrantfile is created for that project/VM, which then can be customized to your needs. To use that customized Vagrantfile then, just run vagrant up from inside your projects directory. Not sure if this solves your problem but it's worth a try I guess. ;-) Btw. you can check if your VM is running with the command vagrant status [machine-name].

For the client infrastructure, I'd shrink-wrap the product with a Windows Installer MSI. The TFS cloud build sever has Windows Installer XML on it and you can use that to build your installer. Deliver the installer to the client and have it do all the work. Just like downloading TFS from MSDN and installing it on an on premises server. You can also publish the MSI on a website and use an autoupdate pattern running on the client to pull it down and execute it.

cross memory attach. How do I get the remote address from a child process to a parent process
The system calls process_vm_readv and process_vm_writev are meant for fast data transfer between processes. They are supposed to be used in addition to some traditional way of interprocess communication. For example, you may use a regular pipe or fifo to transfer the required addresses between your processes. Then you may use those addresses to establish faster process_vm_ communication. The simpliest way to transfer something between forked processes should be the pipe() function (man 2 pipe has a good example of its usage). There are many other ways to do so of course, like using sockets or messages. You can even write an address to a file and let the other process read it.

In Java What is the exit value of a process which is killed in the background through Linux shell using process id
This is not a Java specific question. The return code will be the same for all Unix systems here (at least I have never seen a Unix system not behaving this way): 128 + the number of the signal which caused the process to terminate. No idea for Windows... Therefore, 130 in your case. In C, you'd check (after a call to waitpid() for instance) whether a process has been terminated by a signal using WIFSIGNALED(status).

Symfony2 Process component - unable to create pipe and launch a new process
The file handles are not being garbage collected, so they eventually fill up (os limit or php limit, not sure), but you can fix it by adding an explicit garbage collection call: gc_collect_cycles(); usleep($sleep * 1000000); Also, be forwarned that garbage collection doesn't work very well inside a foreach loop because of the way that php maps the temporary $foo as $bar => $var array variables into memory. If you need it in that part of the code you could switch it to something like this instead, which I think should allow for garbage collection inside the for loop: $processes[] = new Process("ls > /dev/null", null, null, null, 2); $processes[] = new Process("date > /dev/null", null, null, null, 2); $sleep = 0; do { $count = count($processes); for($i = 0; $i < $co

Is a multi process Java program a single process in the context of the actual machine underneath the JVM it is running on?
You're confused between processes and processors. A JVM counts as a single process on your machine, yes. When you start the JVM it runs as a program and it executes Java byte code. A JVM can address all the processors on you machine. When you start a Thread in Java it executes on an available processor.
