  • Monitoring the wall time of a process on windows?

    - by Sean Madden
    Windows Task Manager has the ability to show the current CPU time of any given running process on windows, is there any way (not necessarily through Task Manager) to get the current wall time of a process? An example, let's say I have a script that reliably runs for about 45 minutes. Without adding a progress bar to the script, is there any way to figure out for how long it has been running? The math behind this seems pretty straight forward; WallTime = CurrentWallTime - WallTimeProcessStarted. Likewise, since the math is so simple, is there anyway to get the time that a process was started at?

  • How to express inter project dependencies in Eclipse PDE

    - by Roland Tepp
    I am looking for the best practice of handling inter project dependencies between mixed project types where some of the projects are eclipse plug-in/OSGI bundle projects (an RCP application) and others are just plain old java projects (web services modules). Few of the eclipse plug-ins have dependencies on Java projects. My problem is that at least as far as I've looked, there is no way of cleanly expressing such a dependency in Eclipse PDE environment. I can have plug-in projects depend on other plug-in projects (via Import-Package or Require-Bundle manifest headers), but not of the plain java projects. I seem to be able to have project declare a dependency on a jar from another project in a workspace, but these jar files do not get picked up by neither export nor launch configuration (although, java code editing sees the libraries just fine). The "Java projects" are used for building services to be deployed on an J2EE container (JBoss 4.2.2 for the moment) and produce in some cases multiple jar's - one for deploying to the JBoss ear and another for use by client code (an RCP application). The way we've "solved" this problem for now is that we have 2 more external tools launcher configurations - one for building all the jar's and another for copying these jar's to the plug-in projects. This works (sort of), but the "whole build" and "copy jars" targets incur quite a large build step, bypassing the whole eclipse incremental build feature and by copying the jars instead of just referencing the projects I am decoupling the dependency information and requesting quite a massive workspace refresh that eats up the development time like it was candy. What I would like to have is a much more "natural" workspace setup that would manage dependencies between projects and request incremental rebuilds only as they are needed, be able to use client code from service libraries in an RCP application plug-ins and be able to launch the RCP application with all the necessary classes where they are needed. So can I have my cake and eat it too ;) NOTE To be clear, this is not so much about dependency management and module management at the moment as it is about Eclipse PDE configuration. I am well aware of products like [Maven], [Ivy] and [Buckminster] and they solve a quite different problem (once I've solved the workspace configuration issue, these products can actually come in handy for materializing the workspace and building the product)

  • Mocking inter-method dependencies

    - by Zecrates
    I've recently started using mock objects in my tests, but I'm still very inexperienced with them and unsure of how to use them in some cases. At the moment I'm struggling with how to mock inter-method dependencies (calling method A has an effect on the results of method B), and whether it should even be mocked (in the sense of using a mocking framework) at all? Take for example a Java Iterator? It is easy enough to mock the next() call to return the correct values, but how do I mock hasNext(), which depends on how many times next() has been called? Currently I'm using a List.Iterator as I could find no way to properly mock one. Does Martin Fowler's distinction between mocks and stubs come into play here? Should I rather write my own IteratorMock? Also consider the following example. The method to be tested calls mockObject.setX() and later on mockObject.getX(). Is there any way that I can create such a mock (without writing my own) which will allow the returned value of getX to depend on what was passed to setX?

  • How do I notify Oracle that an IIS Worker Process is about to recycle?

    - by Brien
    I have an ASP.NET web application with an Oracle back end. The worker process recycling in IIS is set for 40 minutes, and when that occurs, the Oracle server sets a mutex lock while it cleans up all of its open connections. During this cleanup (up to a few minutes in duration), all DB requests get a timeout. Is there a way for IIS to notify Oracle that a worker process recycle is about to occur, so Oracle can be smarter about how it cleans up its resources without locking the entire database?

  • How to limit a process to a single CPU core?

    - by Jonathan
    How do you limit a single process program run in a Windows environment to run only on a single CPU on a multi-core machine? Is it the same between a windowed program and a command line program? UPDATE: Reason for doing this: benchmarking various programming languages aspects I need something that would work from the very start of the process, therefore @akseli's answer, although great for other cases, doesn't solve my case

  • Is there a way to snapshot a running process to disk to restore it later?

    - by Sijin
    I usually work with a lot of instances of visual studio open to different projects, I was wondering if there is a way to snapshot/hibernate a running process to disk instead of closing it so that I can open it in the same state as it was quickly. I have a ton of free disk space so wouldn't mind saving the entire process snapshot if it would save me the time in opening up the solution and waiting for the projects to load.

  • How to keep a generic process unique?

    - by Steve Van Opstal
    I'm currently working on a project that makes connection between different banks which send us information on which that project replies. A part of that project configures the different protocols that are used (not every bank uses the same protocol), this runs on a separate server. These processes all have unique id's which are stored in a database. But to save time and money on configurations and new processes, we want to make a generic protocol that banks can use. Because of PCI requirements we have to make a separate process for every bank we connect to. But the generic process has only 1 unique identifier and therefor we cannot keep them apart. Giving every copy of that process a different identifier is as I see it impossible because they run entirely separate. So how do I keep my generic process unique?

  • "Bad apple" algorithm, or process crashes shared sandbox

    - by Roger Lipscombe
    I'm looking for an algorithm to handle the following problem, which I'm (for now) calling the "bad apple" algorithm. The problem I've got a N processes running in M sandboxes, where N M. It's impractical to give each process its own sandbox. At least one of those processes is badly-behaved, and is bringing down the entire sandbox, thus killing all of the other processes. If it was a single badly-behaved process, then I could use a simple bisection to put half of the processes in one sandbox, and half in another sandbox, until I found the miscreant. This could probably be extended by partitioning the set into more than two pieces until the badly-behaved process was found. For example, partitioning into 8 sets allows me to eliminate 7/8 of the search space at each step, and so on. The question If more than one process is badly-behaved -- including the possibility that they're all badly-behaved -- does this naive algorithm "work"? Is it guaranteed to work within some sensible bounds?

  • Is it possible to Kick off a java process under Windows Service with C#?

    - by Wing C. Chen
    I would like to wrap a java program into a windows service with C# using System.ServiceProcess.ServiceBase. So I came up with the following code: /// <summary> /// The main entry point for the application. /// </summary> static void Main() { System.ServiceProcess.ServiceBase.Run(new JavaLauncher()); } protected override void OnStart(string[] args) { Thread _thread; _thread = new Thread(StartService); _thread.Start(); base.OnStart(args); } protected override void OnStop() { Thread _thread; _thread = new Thread(StopService); _thread.Start(); base.OnStop(); } static public void StartService() { System.Diagnostics.Process proc = new System.Diagnostics.Process(); proc.EnableRaisingEvents = false; proc.StartInfo.FileName = "javaw"; proc.StartInfo.Arguments = config.generateLaunchCommand(); proc.Start(); } static public void StopService() { System.Diagnostics.Process proc = new System.Diagnostics.Process(); proc.EnableRaisingEvents = false; proc.StartInfo.FileName = "javaw"; proc.StartInfo.Arguments = "-jar stop.jar"; proc.Start(); } Firstly I had to use Threads in OnStart and OnStop. If not, an exception occurs complaining that the service is terminated because of doing nothing. Secondly, the service can be hooked up to windows smoothly. However, the service terminates a short while after it is started. I looked into the process monitor, only the service process stays alive for that short while, the javaw process never showed up, however. Is there anyone who knows how this can be fixed? It works fine in an ordinary console environment. I think it has something to do with Windows service.

  • Extracting, Transforming, and Loading (ETL) Process

    The process of Extracting, Transforming, and Loading data in to a data warehouse is called Extract Transform Load (ETL) process.  This process can be used to obtain, analyze, and clean data from various data sources so that it can be stored in a uniform manner within a data warehouse. This data can then be used by various business intelligence processes to provide an organization with more of an in depth analysis of the current state of the company and where it is heading. A standard ETL process that might be used by a health care system may include importing all of their patients names, diagnoses and prescriptions in to a unified data warehouse so that trends can be spotted in regards to outbreaks like the flu and also predict potential illness that a patient might be affected by based on other patients with similar symptoms.

  • pass custom environment variables to System.Diagnostics.Process

    - by Mike Ruhlin
    I'm working on an app that invokes external processes like so: ProcessStartInfo startInfo = new ProcessStartInfo(PathToExecutable, Arguments){ ErrorDialog = false, RedirectStandardError = true, RedirectStandardOutput = true, UseShellExecute = false, CreateNoWindow = true, WorkingDirectory = WorkingDirectory }; using (Process process = new Process()) { process.StartInfo = startInfo; process.Start(); process.BeginErrorReadLine(); process.BeginOutputReadLine(); process.WaitForExit(); return process.ExitCode; } One of the processes I'm calling depends on an environment variable that I'd rather not require my users to set. Is there any way to modify the environment variables that get sent to the external process? Ideally I'd be able to make them visible only to the process that's running, but if I have to programmatically set them system-wide, I'll settle for that (but, would UAC force me to run as administrator to do that?) ProcessStartInfo.EnvironmentVariables is read only, so a lot of help that is...

  • Apache2/mod_fcgid/PHP Process Limits Not Respected

    - by Daniel
    I've recently moved to Apache2 / mod_fcgid / PHP from nginx / php_fpm. This is the second server on which I've made this migration, but it's used much less frequently than the first, which is working like a charm. The problem is in the PHP processes that it's spawning. In looking at the mod_fcgid documentation, it appears that the default for killing idle processes is 300 seconds; I've changed that to 20. At this point, I'd be fine if 300 would work - but it's not happening. It's been running for nearly a day now, and server-status shows 12 active processes: Process name: php5 Pid Active Idle Accesses State 19243 84879 14420 11 Ready Process name: php5 Pid Active Idle Accesses State 20954 82143 149 22 Ready 20947 82149 149 22 Ready 20953 82143 149 13 Ready Process name: php5 Pid Active Idle Accesses State 20589 82765 23644 72 Ready Process name: php5 Pid Active Idle Accesses State 17663 86103 2034 117 Ready Process name: php5 Pid Active Idle Accesses State 19862 83961 1976 91 Ready Process name: php5 Pid Active Idle Accesses State 18495 85825 5164 18 Ready Process name: php5 Pid Active Idle Accesses State 25463 75109 23948 24 Ready Process name: php5 Pid Active Idle Accesses State 2466 60019 60016 2 Ready Process name: php5 Pid Active Idle Accesses State 20729 82541 12592 23 Ready Process name: php5 Pid Active Idle Accesses State 22135 80616 46361 6 Ready PHP applications are not being served at this point - Apache is returning a 503. However, it is still serving the server-status module, and mod_mono/Mono 2.10 applications are still being served. The problem is with the PHP. /etc/apache2/mods-available/fcgid.conf... <IfModule mod_fcgid.c> AddHandler fcgid-script .fcgi FcgidConnectTimeout 10 FcgidMaxRequestsPerProcess 500 FcgidIdleTimeout 20 FcgidFixPathinfo 1 FcgidMaxProcesses 10 </IfModule> (heh - Max Processes isn't being respected either...) Of course, fcgid.conf is smylinked in mods-enabled.

  • Any tool(s) for knowing the layout (segments) of running process in Windows?

    - by claws
    I've always been curious about How exactly the process looks in memory? What are the different segments(parts) in it? How exactly will be the program (on the disk) & process (in the memory) are related? My previous question: http://stackoverflow.com/questions/1966920/more-info-on-memory-layout-of-an-executable-program-process In my quest, I finally found a answer. I found this excellent article that cleared most of my queries: http://www.linuxforums.org/articles/understanding-elf-using-readelf-and-objdump_125.html In the above article, author shows how to get different segments of the process (LINUX) & he compares it with its corresponding ELF file. I'm quoting this section here: Courious to see the real layout of process segment? We can use /proc//maps file to reveal it. is the PID of the process we want to observe. Before we move on, we have a small problem here. Our test program runs so fast that it ends before we can even dump the related /proc entry. I use gdb to solve this. You can use another trick such as inserting sleep() before it calls return(). In a console (or a terminal emulator such as xterm) do: $ gdb test (gdb) b main Breakpoint 1 at 0x8048376 (gdb) r Breakpoint 1, 0x08048376 in main () Hold right here, open another console and find out the PID of program "test". If you want the quick way, type: $ cat /proc/`pgrep test`/maps You will see an output like below (you might get different output): [1] 0039d000-003b2000 r-xp 00000000 16:41 1080084 /lib/ld-2.3.3.so [2] 003b2000-003b3000 r--p 00014000 16:41 1080084 /lib/ld-2.3.3.so [3] 003b3000-003b4000 rw-p 00015000 16:41 1080084 /lib/ld-2.3.3.so [4] 003b6000-004cb000 r-xp 00000000 16:41 1080085 /lib/tls/libc-2.3.3.so [5] 004cb000-004cd000 r--p 00115000 16:41 1080085 /lib/tls/libc-2.3.3.so [6] 004cd000-004cf000 rw-p 00117000 16:41 1080085 /lib/tls/libc-2.3.3.so [7] 004cf000-004d1000 rw-p 004cf000 00:00 0 [8] 08048000-08049000 r-xp 00000000 16:06 66970 /tmp/test [9] 08049000-0804a000 rw-p 00000000 16:06 66970 /tmp/test [10] b7fec000-b7fed000 rw-p b7fec000 00:00 0 [11] bffeb000-c0000000 rw-p bffeb000 00:00 0 [12] ffffe000-fffff000 ---p 00000000 00:00 0 Note: I add number on each line as reference. Back to gdb, type: (gdb) q So, in total, we see 12 segment (also known as Virtual Memory Area--VMA). But I want to know about Windows Process & PE file format. Any tool(s) for getting the layout (segments) of running process in Windows? Any other good resources for learning more on this subject? EDIT: Are there any good articles which shows the mapping between PE file sections & VA segments?

  • COM Pointers and process termination

    - by Tony
    Can an unreleased COM pointer to an external process (still alive) cause that process to hang on destruction? Even with TerminateProcess called on it? Process A has a COM interface pointer reference to Process B, now Process B issues a TerminateProcess on A, if some COM interface pointer to Process B in Process A is not released properly, could it be that the process hangs on termination?

  • How to establish a two-way communication between Activity and Service in different process?

    - by steff
    Hi everyone, I'm working on establishing a two-way communication between an Activity and a Service which runs in a different process. Querying the process from the Activity is no big deal. But I want the process to notify the Activity on events. The idea behind it is this: the service runs independently from the actual app. It queries a webserver periodically. If a new task is found on the webserver the process should notify the activity. I found this thread over at AndDev.org but it doesn't seem to work for me. I've been messing around with BroadcastReceiver. I've implemented an interface which should notify the Activity but the problem is that the listener is always null since the Broadcast from the process is done via Intent, hence the class that extends BroadcastReceiver will be newly instantiated. How can I establish a 2-way communication? This has to be possible. Thanks for any help, steff

  • IE9 development tools giving "Unable to attach to the process." error

    - by Urbycoz
    Notice: I have now rebuilt my machine to remove this bug, so I can no longer verify any answers. I recently installed Internet Explorer 9, and activated the development tools by pressing F12; I then clicked "script" and the "start debugging" button but I got the following error: Unable to attach to the process. Another debugger might be attached to the process. I get this message regardless of the site I am on (currently I'm on google.com). I have no other applications running, and have rebooted my machine. Can anyone suggest why this may be appearing?

  • How to set a low process priority for everything spawned from a command prompt in XP?

    - by Binary Worrier
    As a developer, once or twice a week I run a full build on my XP dev machine. This will run at 100% cpu for 30 or 40 minutes, making my machine usless for anything other than basic browsing & email. Is there anyway I can specify that for a given process (i.e. a command prompt) it and any process spawned by it will hae a lower priority, say taking up no more than 60 - 70% of CPU, leaving my machine more usable. I don't mind the build talking 30 or 40% longer, if I still have use of my machine while it's running. Thanks BW P.S. I'd love to be able to throw more hardware at the problem, but that isn't under my control.
