  • I/O Error with PHP5-FPM, ptrace(PEEKDATA) failed

    - by MultiformeIngegno
    I got a lot of these: [NOTICE] child 19214 stopped for tracing [NOTICE] about to trace 19214 [ERROR] ptrace(PEEKDATA) failed: Input/output error (5) [NOTICE] finished trace of 19214 [WARNING] [pool www] child 19208, script 'blahblah.php' executing too slow (30.041419 sec), logging [NOTICE] child 19208 stopped for tracing [NOTICE] about to trace 19208 [ERROR] ptrace(PEEKDATA) failed: Input/output error (5) [NOTICE] finished trace of 19208 [WARNING] [pool www] child 19218, script 'blahblah.php' executing too slow (30.035029 sec), logging And when php reaches max children (at least I presume that's the case) it stops "working"... now I know I can increase max_children (currently set to 9) but there's a way to stop php from "dying"? I'm on a VPS with 1 core and 512 MB of RAM (PHP5-FPM 5.4.4 + APC 3.1.10).

  • How do I configure custom routes when an interface is configured?

    - by ManicDee
    Other Superuser questions have addressed the issue of adding custom routes to access e.g.: multiple networks of a corporate network through one interface, while accessing the Internet through another interface. So assuming that I have a script to add specific routes when en0 is configured, and a separate script to add specific routes when en1 is configured, is there some way I can trigger those scripts to run automatically when Mac OS X/Darwin starts and configures those interfaces? Back in my Linux days, it was possible to add an option in /etc/network/interfaces along the lines of: iface eth0 inet dhcp up /usr/local/sbin/eth0-routes-up Is there something similar for Mac OS X?

  • Runaway version store in tempdb

    - by DavidWimbush
    Today was really a new one. I got back from a week off and found our main production server's tempdb had gone from its usual 200MB to 36GB. Ironically I spent Friday at the most excellent SQLBits VI and one of the sessions I attended was Christian Bolton talking about tempdb issues - including runaway tempdb databases. How just-in-time was that?! I looked into the file growth history and it looks like the problem started when my index maintenance job was chosen as the deadlock victim. (Funny how they almost make it sound like you've won something.) That left tempdb pretty big but for some reason it grew several more times. And since I'd left the file growth at the default 10% (aaargh!) the worse it got the worse it got. The last regrowth event was 2.6GB. Good job I've got Instant Initialization on. Since the Disk Usage report showed it was 99% unallocated I went into the Shrink Files dialogue which helpfully informed me the data file was 250MB.  I'm afraid I've got a life (allegedly) so I restarted the SQL Server service and then immediately ran a script to make the initial size bigger and change the file growth to a number of MB. The script complained that the size was smaller than the current size. Within seconds! WTF? Now I had to find out what was using so much of it. By using the DMV sys.dm_db_file_space_usage I found the problem was in the version store, and using the DMV sys.dm_db_task_space_usage and the Top Transactions by Age report I found that the culprit was a 3rd party database where I had turned on read_committed_snapshot and then not bothered to monitor things properly. Just because something has always worked before doesn't mean it will work in every future case. This application had an implicit transaction that had been running for over 2 hours.

  • getting PHP PDO flavors to work on Mac OS X

    - by Jason S
    I'm running OS X 10.5; it looks like it came with Apache and PHP installed (minus some minor configurations which I turned on per this page; I've used Apache before so I know the basics of how httpd.conf works). I've got a pre-existing script which uses PDO. I've got a MySQL database and can easily configure my script to access the database via PDO MySQL or PDO ODBC. The problem is, that even though I enabled the PDO MySQL and PDO ODBC extensions in php.ini, phpinfo() reports the only PDO drivers are sqlite2 and sqlite. I'm guessing the relevant extension .dll or .so files are not present? How do I get them? note: I'm using the built-in install for PHP. (see apple's page on enabling php, which doesn't say anything about configure or adding additional .so files)

    - by Bilbo
    Im trying to get a PHP script to connect to Asterisks internal mysql database. I tried the to use the standard method for example $con = mysqli_connect("192.168.1.126","root","mysql","asterisk"); However when I log into the asterisk server to access the mysql database all i need it to type "mysql" and im logged in. Im wondering is it possible for my php script to connect to asterisk internal database.

  • The winning combination: Oracle VM Server for x86 + Oracle Sun Fire HW

    - by Karim Berrah
    You might be wondering why OVM Server for x86 (OVM/x86 here and below) should be seriously considered as a nice (business point of view) alternative to standard Hypervisors, if you are virtualizing Oracle Software, especially if you are planning to move to Oracle x86 Hardware (rackmount or blades). Well, let see some "not well known" facts that might interest you and help you in saving more money for your entire company (and not only the Virtulization team). Fact 1: OVM/x86 is considered as a hard partitionning technology (check page 2 of Oracle Server Partitionning Licencing Policies), so if you are buying new servers based on the latest INTEL Xeon E7 CPUs (10 cores per Socket) and have some licencing issues in deploying further Oracle SW, because you are using a hypervisor not recognized as a hard partitionning technology (like VMware), then you need to check here how to do it with OVM . This might help you to continue to deploy your Oracle DB instances on new x86 HW (12 cores, 40 cores, 64 cores servers) in a reasonable way, without having to pay licences for 12 CPU, 40 CPUs or 64 CPUs. You might also consider migrating your legacy Oracle DB DBs to a virtualized environment like OVM/x86 an recover some CPU licences, that can be reused somewhere else in production. Fact 2: OVM/x86 is free to use, without any extra licence for any specific feature (LiveMigration, High Availability, Embedded Management Console). If you want to use it on non Oracle HW, there is a support fee per  system and per year, that is much below VMware support (Oracle VM Premier Limited Support for systems up to 2 CPUs, and Oracle VM Premier Support for any bigger system, independently on the number of populated sockets). Fact 3: support is included with your Oracle x86 HW support (OPS for systems)  and you can re-install on you system Oracle Linux, Oracle Solaris or Oracle VM server for x86, without beeing charged, an keeping the same support level. Fact 4: it is less expensive to virtualize Oracle Linux or Oracle Solaris on OVM/x86 with Oracle HW that any other similar solution with VMware, because all the VMs are then supported and licenced when you buy Oracle HW with OPS. Fact 5: Oracle VM Templates bring you many Virtual Machines already installed, patched and optimized for various Oracle applications. And to be more specific, those templates are fully supported by Oracle, which is not really true when it comes to another hypervisor. By optimized VM Kernel, I mean PV drivers, OVM-ready kernels in the VM, single source clock for all the VMS, better memory management of the VM ... Fact 6: there is no extra costs for a management console. OVM comes with a free OVM Manager package for Linux.  More infos: Latest announcement of OVM/x86 update 2.2.2 A short flash demo of OVM server for x86 A short flash demo on OVM Templates and Virtual Assembly Builder Oracle Linux Support and Oracle VM Support Global Price List  ISVs: Benefits for Independant Sofwtare Vendors (ISVs) in using OVM/x86 Consultant Services: Advanced Customer Services for OVM/x86  Technical Features Best practices and Guideline for OVM with Oracle Blades Reduce TCO and get more Value from your x86 Infrastructure

  • IBM Tivoli Network Manager IP Edition - Job does not run

    - by Thorsten Niehues
    Since our network discovery takes too long I tried to split the biggest job into two parts. The two parts use the same Perl script but have a different scope. I copied a Job (Agent) doing the following: Copied the .agnt file Copied the associated perl script The problem is that one or the other job (changes randomly) does not run. The Disco Process will fail eventually. In the log of the job which does not run I see the following error message: Wed Jul 18 08:48:54 2012 Warning: Failed to send on transport layer found in file CRivObjSockClient.cc at line 1293 - Client My_MacTable_Cis is not connected to service Helper How do I fix this problem?

  • SVN Export or Recursively Remove .SVN Folders

    - by Ben Griswold
    I shared this script with a coworker yesterday. It doesn’t do much; it recursively deletes .svn folders from a source tree.  It comes in handy if you want to share your codebase or you get in a terrible spot with SVN and you just want to start all over. Just blow away all svn artifacts and use your mulligan. It’s true. You can nearly get the same result using the SVN export command which copies your source sans the .svn folders to an alternate location.  The catch is an export only includes those files/folders which exist under version control.  If you want a clean copy of your source – versioned or not – export just might not do. The contents of the .cmd file include the following: for /f "tokens=* delims=" %%i in (’dir /s /b /a:d *.svn’) do ( rd /s /q "%%i" ) Just download and drop the unzipped “SVN Cleanup.cmd” file into the root of the project, execute and away you go.  If you search around enough, I know you can find similar scripts and approaches elsewhere, but I’m still uploading my script for completeness and future reference.

  • Booting from USB on Mac Air (using setup_mac_usb_boot.sh)

    - by Mike O
    So, I've been working on this for hours and it's getting a little tiring. As some of you may know, installing Ubuntu on Macs is frequently an adventure, and I'm experiencing that right now. The part I'm hung up on at the moment is making a bootable USB. I would just use a CD, but my laptop is a MacBook Air (which doesn't have a CD drive), and I don't own an external CD drive. I initially attempted to use the command line method supplied by the Ubuntu documentation here: https://help.ubuntu.com/community/How%20to%20install%20Ubuntu%20on%20MacBook%20using%20USB%20Stick However, that wasn't even recognized by rEFIt even when I made a number of different modifications to the process, so I quickly decided to look elsewhere. I came across this guide: https://help.ubuntu.com/community/MacBookAir4-2#Basic_Installation_Instructions This ended up working to a large extent. If I choose the supplied grub from rEFIt, it will bring me to the Ubuntu grub, asking me to try it, install, or check the disk. And if I choose to boot Linux directly from rEFIt, it will bring me to the language selection menu. But when I make my selection from either of these menus it pauses for about ten seconds and then gives me a command line error message. It begins with kernel panic - not syncing timer doesn't work through interrupt, and then shows about eight file names. Does anyone here have any ideas as to what can be causing this? I also tried the script with both Ubuntu 11.10 (the current version when the script was written) and 12.04.

  • Emacs: methods for debugging python

    - by Tom Willis
    I use emacs for all my code edit needs. Typically, I will use M-x compile to run my test runner which I would say gets me about 70% of what I need to do to keep the code on track however lately I've been wondering how it might be possible to use M-x pdb on occasions where it would be nice to hit a breakpoint and inspect things. In my googling I've found some things that suggest that this is useful/possible. However I have not managed to get it working in a way that I fully understand. I don't know if it's the combination of buildout + appengine that might be making it more difficult but when I try to do something like M-x pdb Run pdb (like this): /Users/twillis/projects/hydrant/bin/python /Users/twillis/bin/pdb /Users/twillis/projects/hydrant/bin/devappserver /Users/twillis/projects/hydrant/parts/hydrant-app/ Where .../bin/python is the interpreter buildout makes with the path set for all the eggs. ~/bin/pdb is a simple script to call into pdb.main using the current python interpreter HellooKitty:hydrant twillis$ cat ~/bin/pdb #! /usr/bin/env python if __name__ == "__main__": import sys sys.version_info import pdb pdb.main() HellooKitty:hydrant twillis$ .../bin/devappserver is the dev_appserver script that the buildout recipe makes for gae project and .../parts/hydrant-app is the path to the app.yaml I am first presented with a prompt Current directory is /Users/twillis/bin/ C-c C-f Nothing happens but HellooKitty:hydrant twillis$ ps aux | grep pdb twillis 469 100.0 1.6 168488 67188 s002 Rs+ 1:03PM 0:52.19 /usr/local/bin/python2.5 /Users/twillis/projects/hydrant/bin/python /Users/twillis/bin/pdb /Users/twillis/projects/hydrant/bin/devappserver /Users/twillis/projects/hydrant/parts/hydrant-app/ twillis 477 0.0 0.0 2435120 420 s000 R+ 1:05PM 0:00.00 grep pdb HellooKitty:hydrant twillis$ something is happening C-x [space] will report that a breakpoint has been set. But I can't manage to get get things going. It feels like I am missing something obvious here. Am I? So, is interactive debugging in emacs worthwhile? is interactive debugging a google appengine app possible? Any suggestions on how I might get this working?

  • Setting up Google Analytics for multiple subdomains

    - by Andrew G. Johnson
    so first here's a snippet of my current Analytics javascript: var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-30490730-1']); _gaq.push(['_setDomainName', '.apartmentjunkie.com']); _gaq.push(['_setSiteSpeedSampleRate', 100]); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(ga, s); })(); So if you wanna have a quick peak at the site the url is ApartmentJunkie.com, keep in mind the site is pretty bare bones but you'll get the idea -- basically it's very similar to craigslist in the sense that it's in the local space so people pick a city then get sent to a subdomain that is specific for that city, e.g. winnipeg.mb.apartmentjunkie.com. I put that up late last night then had a look at the analytics and found that I am seeing only the request uri portion of the URLs in analytics as I would with any other site only with this one it's a problem as winnipeg.mb.apartmentjunkie.com/map/ and brandon.mb.apartmentjunkie.com/map/ are two different pages and shouldn't be lumped together as /map/ I know the kneejerk response is likely going to be "hey just setup a different google analytics profile for each subdomain" but there will eventually be a lot of subdomains so google's cap of 50 is going to be too limited and even more important I want to see the data in aggregate for the most part. I am thinking of making a change to the javascript, to something like: _gaq.push(['_trackPageview',String(document.domain) + String(document.location)]); But am unsure if this is the best way and figured someone else on wm.se would have had a similar situation that they could talk a bit about.

  • SQL SERVER – How to Change Compatibility of Database to SQL Server 2014

    - by Pinal Dave
    Yesterday I wrote about how we can install SQL Server 2014. Right after the blog post was live, I received a question from the developer that he has installed SQL Server 2014 and attached a database file from previous version of SQL Server. Right after attaching database, he was not able to work with the latest features of Cardinality Estimation. As soon as he sent me email I realize what has happened exactly. When he attached database, the database compatibility was set to still of the earlier version of SQL Server. To use most of the latest features of SQL Server 2014, one has to change the compatibility level of the database to the latest version (i.e. 120). Here are two different ways how we can change the compatibility of database to SQL Server 2014′s version. 1) Using Management Studio For this method first to go database and right click over it. Now select properties. On this screen user can change the compatibility level to 120. 2) Using T-SQL Script. You can execute following script and change the compatibility settings to 120. USE [master] GO ALTER DATABASE [AdventureWorks2012] SET COMPATIBILITY_LEVEL = 120 GO   Well, it is that easy :-) Reference: Pinal Dave (http://blog.SQLAuthority.com)Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL

  • Is there a registry key change that will by-pass the Windows Domain Join Welcome page?

    - by user1256194
    I'm scripting some Windows Server 2008 R2 builds using Power Shell. Some software needs to be installed after the server has joined the domain. Since I want to automate everything, I'm looking to by-pass the domain controllers Welcome page using a registry hack script. I work for a large company and the Active Directory people are unwilling to change group policy. I figure if it's a registry key I can script the change, install the software, replace the key and reboot as the final step. Is there a registry key change that will by-pass the Domain Join Welcome page?

  • XML Schema For MBSA Reports

    - by Steve Hawkins
    I'm in the process of creating a script to run the command line version of Microsoft Baseline Security Analyzer (mbsacli.exe) against all of our servers. Since the MBSA reports are provided as XML documents, I should be able to write a script or small program to parse the XML looking for errors / issues. I'm wondering if anyone knows whether or not the XML schema for the MBSA reports is documented anywhere -- I have goggled this, and cant seem to find any trace of it. I've run across a few articles that address bits and pieces, but nothing that addresses the complete schema. Yes, I could just reverse engineer the XML, but I would like to understand a little more about the meaning of some of the tags. Thanks...

  • Is it possible to skip .rvmrc confirmation?

    - by Viacheslav Molokov
    We are using RVM for managing Ruby installations and environments. Usually we are using this .rvmrc script: #!/bin/bash if [ ! -e '.version' ]; then VERSION=`pwd | sed 's/[a-z/-]//g'` echo $VERSION > .version rvm gemset create $VERSION fi VERSION=`cat .version` rvm use 1.9.2@$VERSION This script forces RVM to create new gem environment for each our project/version. But each time we was deploying new version RVM asks us to confirm new .rvmrc file. When we cd to this directory first time, we are getting something like: =============================================================== = NOTICE: = =============================================================== = RVM has encountered a not yet trusted .rvmrc file in the = = current working directory which may contain nasty code. = = = = Examine the contents of this file to be sure the contents = = are good before trusting it! = = = = Press 'q' to exit the reader when finished reading the file = =============================================================== (press enter to continue when ready) This is not as bad for development environments, but with auto deploy it require to manually confirm each new version on each server. Is it possible to skip this confirmation?

  • zero-config CGI enabled web server

    - by halp
    To serve static content of a directory over http, one can simply navigate to that directory and type: python -m SimpleHTTPServer 11111 which will start a http server on port 11111. This hack is nice because it requires zero-config: no stand-alone web server, no config files at all. Is it possible to extend this example, or have an alternate way to achieve this goal, but also have CGI support? The final goal is to have a quick and lazy way of serving a web site from a certain directory. The site has static content (HTML pages, images), but also a CGI script. The CGI script must work properly when accessed via browser. Of course I could setup a virtual host in apache, allow CGI inside it etc. But that's not a zero-config approach.

  • How to Create a Minimize All Windows (Win + M) Hotkey for Mac OS X

    - by The Geek
    Windows users have been able to minimize every window on their desktop ever since keyboards with the Win key started showing up — just tap WIN + M on your keyboard, and every window is minimized. For Mac OS X, it’s not quite as simple. You can, of course, use the CMD + OPT + H + M shortcut key combination to hide most windows… but that’s a lot of keys to hit at once, and it doesn’t always minimize everything in my experience. So like everything else I wanted from Windows, it was time to figure out how to get it on OS X as well. This method uses QuickSilver to provide the shortcut key trigger — if there’s a better way to do that, please let us know. Luckily OS X includes a nice scripting platform, and we can use the following script from a helpful person over at SuperUser to make this all happen. tell application "Finder" to activate tell application "System Events" tell application process "Finder" tell menu bar 1 click menu item "Hide Others" of menu of menu bar item "Finder" click menu item "Minimize All" of menu of menu bar item "Window" end tell end tell end tell Open up a new AppleScript Editor window and paste in the script from above. Then go to File and Save.

  • $TERM set to "dumb" causes problems with suspend

    - by julkiewicz
    I've just upgraded from 11.04 to 11.10. So far I love it, everything seems just so much snappier. Now I just have one minor issue. When I try to suspend my laptop, it doesn't work - instead it fades out the screen, blocks it and then instantly wakes back. I've checked the logs in /var/log/pm-suspend.log and this fragment seems relevant: /usr/lib/pm-utils/sleep.d/000kernel-change suspend suspend: success. Running hook /usr/lib/pm-utils/sleep.d/00clear suspend suspend: TERM environment variable not set. /usr/lib/pm-utils/sleep.d/00clear suspend suspend: Returned exit code 1. Sat Nov 19 12:23:20 CET 2011: Inhibit found, will not perform suspend Sat Nov 19 12:23:20 CET 2011: Running hooks for resume The mentioned script at /usr/lib/pm-utils/sleep.d/00clear reads: #!/bin/bash clear When I open a terminal anywhere by hand, $TERM is set to either "linux" or "xterm". However somehow when the 00clear command is executed $TERM is set to "dumb". Two questions: What is the correct value for $TERM when running 00clear script? Where can I set it up? I've looked for solutions on the web, however I could only find information on how to configure $TERM in a regular terminal (and this one is set properly).

  • Installed Ubuntu 14.04LTS

    - by user291729
    On my laptop which came pre-installed with Windows 8.1. Felt I needed to see the competition for myself to establish which was a better OS. So I followed the channels to dual boot. All seemed fine and I accessed Ubuntu with no issues after selecting this from the menu to select the OS. I should add that the boot method was changed to legacy. However, since using Ubuntu, I no longer have the ability to select the OS. The laptop simply logs straight into Ubuntu. I therefore attempted to access the recovery options, only it appears the Windows 8 bootloader has somehow been corrupted as I am now told to use the Windows 8 recovery disc (which, as this was pre-installed - I do not have). Left with no other alternative, I have scoured these forums without success, and so I am hoping someone in the know (or who has experienced similar) can help. I have tried boot repair again without success. On rebooting I am only presented with a basic splash screen asking me to select Ubuntu, Memtest, Windows 8 Recovery or Windows 8 Bootloader (The bootloaders again require I insert the disc).

However, if I'm to try using Ubuntu again then there is the risk this problem may come back. Again, I did not do anything manually - the installer did everything (with the exception of changing the boot to Legacy to allow the booting of another bootloader). LiveCD works but doesn't give me the options that I've seen here and as mentioned earlier, only boot recovery only gives me the options as mentioned earlier. Also this fails to load via USB (possibly because HDD comes before USB in the boot order?). Being used to a Windows environment, the Ubuntu (and Linux) environment is a dive at a less than comfortable depth at present (but one I fully intend to get to grips with - especially the commands being more common via Terminal). I very much appreciate the help with this guys.

  • please explain my fio results - is O_SYNC|O_DIRECT misbehaving on linux?

    - by Zoltan
    I'm going mad over figuring out what the problem could be with one of our storage boxes. With a simple fio script I'm testing random writes using bs=1M and direct=1. The SSD is a Samsung 840pro attached to an LSI HBA (3Gbit/s ports). This is the result I'm getting under FreeBSD 9.1: WRITE: io=13169MB, aggrb=224743KB/s, minb=224743KB/s, maxb=224743KB/s, mint=60002msec, maxt=60002msec This is regardless of sync being set to 0 or 1. On linux, this is the result with sync=0: WRITE: io=14828MB, aggrb=253060KB/s, minb=253060KB/s, maxb=253060KB/s, mint=60001msec, maxt=60001msec and with sync=1: WRITE: io=6360.0MB, aggrb=108542KB/s, minb=108542KB/s, maxb=108542KB/s, mint=60001msec, maxt=60001msec My understanding is that since I'm operating on the raw block device, O_SYNC should not make any difference - there's no filesystem, any barrier, anything between the writes and the drive itself. Especially with O_DIRECT|O_SYNC set. Any ideas? For reference, here's the fio script I'm testing with: [global] bs=1M ioengine=sync iodepth=4 size=16g direct=1 runtime=60 filename=/dev/sdh sync=1 [rand-write] rw=randwrite stonewall
