  • How to stop processes from going into the page file

    - by Not a Name
    I have a server, and windows vista, 64-bit, 4gb ram. Sometimes the server randomly drops into the page file, and disconnects everyone who was online. Only after I click the cmd.exe window does it comes back out. How do I mark a program as not eligible for the page file? If this is relevant, I'm using a Minecraft server with the following command line arguments: java -server -Xmx256M -Xms256M -XX:+UseConcMarkSweepGC -XX:+DisableExplicitGC -XX:+UseAdaptiveGCBoundary -XX:MaxGCPauseMillis=200 -XX:-UseGCOverheadLimit -XX:SurvivorRatio=16 -Xnoclassgc -XX:UseSSE=3 -XX:ParallelGCThreads=3 -jar minecraft_server.jar nogui

  • Spawning HTTPD processes

    - by felix001
    Can any confirm how Apache spawns new children ? As in if I connect to a webserver (HTTP 1.0 / no keep alive) and issue a HTTP /GET I will be spawned a new HTTPD child. If then issue another HTTP /GET then a new TCP connection will be built. However will I use the same child process of would I spawn a new one ? Also if I was using HTTP 1.1 (with keep-alive) and reused the same TCP connection, would the httpd process/spawning be any different to that if I wasnt using keepalive ? Thanks,

  • Timing startup processes?

    - by acidzombie24
    My Windows 7 use to boot up fast and now its getting rather slow. I suspect one program is eating up all the time yet i cant tell what it is since task manager shows <40% of the cpu being used. What can i use to track how long each process takes when my computer boots/starts up? Note: Except for launchy which i used before my comp became slow, all my startup and services are all signed and known (broadcom, VMWare, Google Inc, Intel, etc) Note2: I am mostly considering the time it takes after i login but i suspect the time before that is slightly slower (i dont think very much though)

  • How do projects manage chef cookbooks when multiple teams manage multiple sets of cookbooks?

    - by strife25
    I am wondering how projects that have multiple component teams manage their sets of cookbooks? We are trying to figure out how we can have an ops team provide a set of "common component" cookbooks that can be re-used by other teams that will also write their own cookbooks. For example, the ops team should own the Java cookbook, while a component manages their cookbooks written for their component or build engines. From my little experience with chef server, this kind of workflow seems to not be well supported since the server stores and manages all cookbooks - so there is a potential to overwrite a cookbook written by another team. How do other projects deal with this type of problem?

  • how to use SharePoint to manage work items (tasks)

    - by George2
    Hello everyone, I am using SharePoint 2007 Enterprise + Publishing portal template + Windows Server 2008. I want to utilize SharePoint to manage work items and I want to let gurus here to recommend me some good tutorials for newbie like me for this field (better through configuration ways, not through coding). My requirements are, Manager could assign task to workers, and manager could edit task description, due date; Workers could see the tasks assigned to them, and could update task execution status (may attach some documents); Manager could review all tasks assigned by the manager, and updates by workers; Better to have a calendar view with the tasks. thanks in advance, George

  • Configure Supervisor to manage init.d services

    - by Eduard Luca
    I installed uwsgi and created a bash script, which allows me to start/stop uwsgi in the following manner: service uwsgi [start|stop]. This bash script is located in /etc/init.d/uwsgi. Now, I want to (politely) ask Supervisor to use that script to manage the uwsgi process. All the tutorials indicate that this is not the way to do it, however I do want to be able to do both service uwsgi stop and supervisorctl stop uwsgi (not sure if I nailed the syntax of the latter) -- even though I am aware that the first one will not in fact stop my service because supervisor will restart it (that's exactly what I need). Note that I'm using uwsgi in emperor mode if that matters in any way.

  • Macro to manage sport ranking and calendar?

    - by Ale
    I need to write a macro to manage ranking and calendar for curling turnament. The event will follow the Shenkel system first match determined by general draw after that every team has played one match is possible to determine the first ranking second match determined by the rule: 1st vs. 2nd - 3rd vs. 4th - 5th vs. 6th and so on after that every team has played two matches is possible to determine the second ranking and so on until the end (3 to 5 matches normally). Another rule is that from the second match is not possible to play against a team that I played before! I was thinking to use MS-excel but also Calc (both LibreOffice/OpenOffice) should be fine. Thanks in advanced

  • SSH reverse tunnel to monitor and manage remote devices

    - by acid_crucifix
    I have a set a distributed set of devices running Ubuntu 12.04 that I am distributing to clients. I would like to manage them remotely. They may not have fixed IPs and potentially might be behind firewalls. What I am planning to do is have the devices (permanently connected to the net) poll a request URL and based on the response open a reverse tunnel to my server, so that I can access them via that tunnel. Most of what I read about reverse tunnel over SSH is for single use cases and very little about heavy production usage. Is there some reason for this, security issues? or stability? Any help would be much obliged.

  • Manage gmail label on iPad

    - by tinmaru
    My iPad is configured with gmail (using an exchange account, not imap but I don't think it is relevant). I would like to create and manage folder in the mail app. I noticed that it is sync to my gmail label. - this feature is not possible in the native mail app, neither in the official gmail app - the only way to do it is to use a pc or a mac (with the gmail desktop version) - in the gmail mobile web version, I cannot find any button to force desktop version. What is the simplest workaround?

  • Is there an "embedded DBMS" to support multiple writer applications (processes) on the same db files

    - by Amir Moghimi
    I need to know if there is any embedded DBMS (preferably in Java and not necessarily relational) which supports multiple writer applications (processes) on the same set of db files. BerkeleyDB supports multiple readers but just one writer. I need multiple writers and multiple readers. UPDATE: It is not a multiple connection issue. I mean I do not need multiple connections to a running DBMS application (process) to write data. I need multiple DBMS applications (processes) to commit on the same storage files. HSQLDB, H2, JavaDB (Derby) and MongoDB do not support this feature. I think that there may be some File System limitations that prohibit this. If so, is there a File System that allows multiple writers on a single file? Use Case: The use case is a high-throughput clustered system that intends to store its high-volume business log entries into a SAN storage. Storing business logs in separate files for each server does not fit because query and indexing capabilities are needed on the whole biz logs. Because "a SAN typically is its own network of storage devices that are generally not accessible through the regular network by regular devices", I want to use SAN network bandwidth for logging while cluster LAN bandwidth is being used for other server to server and client to server communications.

  • Most efficient way to send images across processes

    - by Heinrich Ulbricht
    Goal Pass images generated by one process efficiently and at very high speed to another process. The two processes run on the same machine and on the same desktop. The operating system may be WinXP, Vista and Win7. Detailled description The first process is solely for controlling the communication with a device which produces the images. These images are about 500x300px in size and may be updated up to several hundred times per second. The second process needs these images to display them. The first process uses a third party API to paint the images from the device to a HDC. This HDC has to be provided by me. Note: There is already a connection open between the two processes. They are communicating via anonymous pipes and share memory mapped file views. Thoughts How would I achieve this goal with as little work as possible? And I mean both work for me and the computer. I am using Delphi, so maybe there is some component available for doing this? I think I could always paint to any image component's HDC, save the content to memory stream, copy the contents via the memory mapped file, unpack it on the other side and paint it there to the destination HDC. I also read about a IPicture interface which can be used to marshall images. What are your ideas? I appreciate every thought on this!

  • Porting - Shared Memory x32 & x64 processes

    - by dpb
    A 32 bit host Windows application setups shared memory (using memory mapped file / CreateFileMapping() API), and then other 32 bit client processes use this shared memory to communicate with each other. I am planning to port the host application to 64 bit platform and once it is ready, I intend that both 32 bit and 64 bit client processes should be able to use the shared memory setup by the main 64 bit host application. The original code written for host x32 application uses "size_t" almost everywhere, since this differs from 4 bytes to 8 bytes as we move from x32 to x64, I am looking for replacing it. I intend to replace "size_t" by "unsigned long long", so that its size will be same on 32 bit & 64 bit. Can you please suggest me better alternative? Also, will the use of "unsigned long long" have performance impact on x32 app .. i guess yes? Research Done - Found very useful articles - a) 20 issue in porting from 32 bit to 64 bit (www.viva64.com) b) No way to restrict/change "size_t" on x64 platform to 4 bytes using compiler flags or any hooks/crooks since it is typedef

  • Why are there tons of PHP processes open on my server?

    - by fiftyeight
    Today I saw that a website of mine isn't working so I ssh'd to the server and executed ps -eF. I see about 200 PHP processes that are running all for 4 hours. Apache is built with mpm event and mod fcgid. I killed all the PHP processes and now it's running fine, why does this happen? is this expected behavior? I don't really understand how processes how Apache keeps track of the number of PHP processes and their process IDs, so it would be nice if someone can also give some reference when I can read about this. Also, I used the "ab" command (Apache Benchmark) to see if this happens all the time, so I ran it about 4-5 times with 30 concurrent requests and again there are like 150 PHP processes running, when I keep running "ab" now it doesn't spawn more processes and the website is still working. Please shed some light on this! Thank you :)

  • What happens to running processes when I lose a remote connection to a *nix box?

    - by David Marble
    I occasionally lose my remote SSH connection to my VPS. I use screen for long-running processes, but am wondering what happens to the processes I had running aside from those run within a screen session if I lose the connection to the box. When I re-establish a connection to the box, what happened to the bash and sshd processes that were running when I lost the connection? Today I lost connection repeatedly and noticed many more bash and sshd processes than usual. If there are processes hanging around, do I need to kill them? How could I determine which processes were abandoned from my previous session? Thanks for any replies!

  • how to install daemontools (supervise) on centos 5?

    - by solsol
    I'd like to use supervise to monitor httpd, mysqld and hudson processes on Centos 5. When any of these processes go down I'd like to use a tool to automatically restart them. I've read and heard about supervise, but couldn't find a way to install it on centos. Can anyone help me with that? Any other tools are also good, as long as they can be easily installed on centos 5 and allow me to automatically restart httpd, mysqld, hudson. Thanks for your help!

  • Exclude a process from being listed in `top`

    - by warren
    Is it possible to exclude some processes from being reported by top? For example, I would like to exclude itself from its listing (ie, I don't want top to show in the process list). I would also like to be able to exclude processes that do not belong to the user running top (except for root). Is this possible? If so, how? If not, is there a similar tool that will do what I want (that does not involve running something like ps frequently).
