  • How to monitor process hogging CPU on a remote server

    - by sergeb
    I have a remotely hosted (virtual, VMware) dedicated server (Windows 2008 Server Web edition w/ SP1) that I can only connect to over Remote Desktop. Lately, a process hogs CPU for ~40 minutes most every day (at a random hour) and brings all web sites on the server down. While this is going on I also cannot connect using Remote Desktop to investigate on what is that process... Promptly after 40 min I can RD and the first thing I see on the Perf Monitor is that there was something topping the CPU at 100% and stops just before I'm able to RD... I'm aware of the beginning and end of this for I have monitors setup that email me up/down status of the web sites but I'm locked out while this is happening - can't RD to the server until it's over (and too late to see the Task Manager/Process Explorer picture). What is the best way/tool to setup on the server to continuously monitor all processes so when this happens I login and "replay" it to find the process causing this trouble? (I have no control over the virtual/VMware setup for it is hosted by a 3rd-party but I have most full control over my dedicated machine) Thanks in advance!

  • Why is my Compaq NC8430 laptop so darned HOT ?

    - by Cheeso
    For a long time I've had a Compaq nc8430 laptop. It's nearly 3 years old now. Originally shipped with WinXP, but I installed Vista on it. From the very start it was not a good experience. This thing has one of those "stickpoint" mice, which I like. After a while, I noticed that the computer was generating lots and lots of heat. So much heat, that the stickpoint bumper would melt and disintegrate. Normally I would expect heat if the CPU was working hard, but even when the CPU was idle, the computer was hot. Much too hot to keep on my lap. Turns out this is not an uncommon problem. I installed the HWmonitor tool, and found that the CPU temp was 82C when it was plugged in - pretty darn hot. And because the temp was so high, the fan never turned off, so the laptop was as loud as a jet engine, always. If I unplugged it from A/C power, the screen would dim and the temperature would decrease, and the fan noise would lessen, but still, it was too loud. It's totally unusable. What is the problem?

  • syslog-ng and nging logs to mysql

    - by Katafalkas
    So couple of days ago I asked how to log php and nginx logs to centralized MySQL database, and m0ntassar gave a perfect answer :) cheer ! The problem I am facing now is that I can not seem to get it working. syslog-ng version: # syslog-ng --version syslog-ng 3.2.5 This is my nginx log format: log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; syslog-ng source: source nginx { file( "/var/log/nginx/tg-test-3.access.log" follow_freq(1) flags(no-parse) ); }; syslog-ng destination: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("superpasswd") database("syslog") table("nginx") columns("remote_addr","remote_user","time_local","request","status","body_bytes_sent","http_ referer","http_user_agent","http_x_forwarded_for") values("$REMOTE_ADDR", "$REMOTE_USER", "$TIME_LOCAL", "$REQUEST", "$STATUS","$BODY_BYTES_SENT", "$HTTP_REFERER", "$HTTP_USER_AGENT", "$HTTP_X_FORWARDED_FOR")); }; MySQL table for testing purposes: CREATE TABLE `nginx` ( `remote_addr` varchar(100) DEFAULT NULL, `remote_user` varchar(100) DEFAULT NULL, `time` varchar(100) DEFAULT NULL, `request` varchar(100) DEFAULT NULL, `status` varchar(100) DEFAULT NULL, `body_bytes_sent` varchar(100) DEFAULT NULL, `http_referer` varchar(100) DEFAULT NULL, `http_user_agent` varchar(100) DEFAULT NULL, `http_x_forwarded_for` varchar(100) DEFAULT NULL, `time_local` text, `datetime` text, `host` text, `program` text, `pid` text, `message` text ) ENGINE=InnoDB DEFAULT CHARSET=latin1 Now first thing that goes wrong is when I restart syslog-ng: # /etc/init.d/syslog-ng restart Stopping syslog-ng: [ OK ] Starting syslog-ng: WARNING: You are using the default values for columns(), indexes() or values(), please specify these explicitly as the default will be dropped in the future; [ OK ] I have tried creating a file destination and it all works fine, and then I have tried replacing my destination with: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("kosmodromas") database("syslog") table("nginx") columns("datetime", "host", "program", "pid", "message") values("$R_DATE", "$HOST", "$PROGRAM", "$PID", "$MSGONLY") indexes("datetime", "host", "program", "pid", "message")); }; Which did work and it was writing stuff to mysql, The problem is that I want to write stuff to in exact format as nginx log format is. I assume that I am missing something really simple or I need to do some parsing between source and destination. Any help will be much appreciated :)

  • Toshiba laptop cd drive read causes OS to totally freeze

    - by Fujishiro
    Okay I'll try to write an understandable summary. Forgive me if I'll fail with that attempt though. So. There is a Toshiba Satellite notebook. Got Windows 7 x86 Professional (OEM) installed on it, everything is fine (okay.. somewhat). The problem. If you put an audio or any kind of disc into the drive, something starts to eat the PC. Back then when the owner told me about this, he put an audio disc into the lappy. Winamp caused the IO load, 100%. Tried taskkill, taskkill /T, tried powershell, EVERYTHING. You just can NOT kill winamp or anything which becomes the blocker at that time. Even if you kill almost everything, laptop won't do a clear shutdown. Also I tried to use the force switch at 'shutdown' from cmd, but no use. (So: At these times you can use the laptop, but the blocker/explorer/disc becomes gray as a non-responding app. You can try to kill them, but that won't work, nor you can shutdown the machine). (Also tried using PID, but no use. For the highest IO I used the "select columns" from Task Manager and enabled the IO columns.) My first hunch was the problematic disc, autoplay and it tries to read tries to read (still shouldn't kill the PC). Disabled autoplay, removed winamp. Tried other software, etc. Everything was ok. Few days later the owner tried to put a disc into the machine and it started to reproduce the same symptoms but with a totally different disc. Uhm what to know. Virus is not an option, protected by BitDefender (valid license) and Spybot. Thanks if you have ANY idea about this strange problem. ps.: For now, the owner uses Daemon tools + Blindwrite as an alternative for those apps which wouldnt start without the disc.

  • HTPC/DVR computer won't go into standby

    - by Robert
    When I select Start-Turn off computer-Standby the 'turn off computer' option window closes, and then nothing else happens. I can start new applications, and Windows acts like I never selected standby. I ran it for several hours after that. If I have a TV program scheduled to record when I select standby I get a window (the Pinnacle TV software) asking if I'm sure, there are programs scheduled to record - and the computer just keeps running after I select yes, never going into standby. I added that detail as it shows the standby process is starting. [This problem also happens if a TV program is not scheduled, so the scheduler task in not running/in memory. This problem happens regardless of whether I'm not watching TV. This problem happens regardless of whether Media Center is running (it usually isn't, I'm using Pinnacle to watch TV).] I looked at "How to troubleshoot hibernation and standby issues in Windows XP" http://support.microsoft.com/kb/907477 - ACPI is enabled, and "standby" is an option in "Power Options Properties." So it appears to be setup correctly. Windows XP SP3 Media Center Edition, all current updates installed.

  • Create Windows AMI with instance storage

    - by Jonathan Oliver
    I have a business use case and workflow where local/instance/ephemeral storage for an EC2 instance is ideal. Unfortunately I'm coupled to a Windows platform for this particular task and the EC2 Windows offering appears to have some deficiencies related to AMI creation. In essence, I'm trying to figure out if there's a way to attach local instance storage to a Windows EC2 instance using the typical command line interface (because the Amazon Website GUI doesn't support it) and then to somehow create an AMI based upon that. I've tried creating a snapshot and then creating a Windows AMI based upon the snapshot, but of course the docs say this is unsupported and makes an unbootable AMI. In short, here's what I'm trying to do: Be able to run a Windows instance (EBS/S3 instance doesn't matter) Attach local instance storage as drive D: Persist that configuration as an AMI such that I can start lots of them as necessary from either the GUI, command line, or REST API. Be able to take a launched instance, update software, shutdown, and create another AMI based upon that. Wash, rinse, repeat. One other potential option which isn't horrible, but isn't ideal is to create an AMI which has 2 EBS volumes already attached (system+apps and data). Essentially, every time I startup an instance based upon the AMI it'll create 2 new EBS volumes of pre-determined size. I'm trying to avoid that scenario if possible.

  • What would keep a Microsoft Word AutoNew() macro from running?

    - by Chris Nelson
    I'm using Microsoft Office 2003 and creating a bunch of template documents to standardize some tasks. I know it's standard practice to put the templates in an certain place Office expects to find them but that won't work for me. What I want is to have "My Template Foo.dot" and "My Template Bar.dot", etc. in the "My Foo Bar Stuff" on a shared drive and users will double click on the template to create a new Foo or Bar. What's I'd really like is for the user to double click on the Foo template and be prompted for a couple of items related to their task (e.g., a project number) and have a script in the template change the name that Save will default to something like "Foo for Project 1234.doc". I asked on Google Groups and got an answer that worked....for a while. Then my AutoNew macro stopped kicking in when I created a new document by double clicking on the template. I have no idea why or how to debug it. I'm a software engineering with 25+ years of experience but a complete Office automation noob. Specific solutions and pointers to "this is how to automate Word" FAQs are welcome. Thanks.

  • Multiple VM environment for developing/testing

    - by Hippo
    I was asked to create a setup for automated deployment, configuration, installation/updates of websites. A bunch of small websites will be bundled on one server. If more website will come up a new server will be created... I decided to us chef for this task. All servers will be running Ubuntu at the same version and configuration. The actual question: Everything needs to be tested properly before starting live deployment, so my question is: What is the best virtualisation tool to run multiple (5 - 10) virtual machines on a Ubuntu Laptop? Requirements: easy setup, fast (clone/snapshot of VMs) All VMs should be easily connected to the internet and should be able to communicate to each other (Open-Source / free would be great) So far I looked into: Virtual box is more for Desktop virtualisation, Cloning not possible, every new machine needs to be installed VMware Player Any suggestions? If there are any question about what I am doing please comment on this question, I will answer as soon as possible. This question is not about the actual set up, it is about a nice working environment.

  • GRE Tunnel over IPsec with Loopback

    - by Alek
    I'm having a really hard time trying to estabilish a VPN connection using a GRE over IPsec tunnel. The problem is that it involves some sort of "loopback" connection which I don't understand -- let alone be able to configure --, and the only help I could find is related to configuring Cisco routers. My network is composed of a router and a single host running Debian Linux. My task is to create a GRE tunnel over an IPsec infrastructure, which is particularly intended to route multicast traffic between my network, which I am allowed to configure, and a remote network, for which I only bear a form containing some setup information (IP addresses and phase information for IPsec). For now it suffices to estabilish a communication between this single host and the remote network, but in the future it will be desirable for the traffic to be routed to other machines on my network. As I said this GRE tunnel involves a "loopback" connection which I have no idea of how to configure. From my previous understanding, a loopback connection is simply a local pseudo-device used mostly for testing purposes, but in this context it might be something more specific that I do not have the knowledge of. I have managed to properly estabilish the IPsec communication using racoon and ipsec-tools, and I believe I'm familiar with the creation of tunnels and addition of addresses to interfaces using ip, so the focus is on the GRE step. The worst part is that the remote peers do not respond to ping requests and the debugging of the general setup is very difficult due to the encrypted nature of the traffic. There are two pairs of IP addresses involved: one pair for the GRE tunnel peer-to-peer connection and one pair for the "loopback" part. There is also an IP range involved, which is supposed to be the final IP addresses for the hosts inside the VPN. My question is: how (or if) can this setup be done? Do I need some special software or another daemon, or does the Linux kernel handle every aspect of the GRE/IPsec tunneling? Please inform me if any extra information could be useful. Any help is greatly appreciated.

  • how to uninstall ubuntu 8 from ubuntu 10 dual boot

    - by umar
    I have ubuntu 8.04 and ubuntu 10.04 on my laptop, and i want to reclaim all the ubuntu 8 space so that i have just one operating system on my laptop. how can i do it? the output of sudo fdisk -l is as follows: sudo fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x31a431a3 Device Boot Start End Blocks Id System /dev/sda1 * 1 4959 39833136 83 Linux /dev/sda2 4960 5233 2200905 82 Linux swap / Solaris /dev/sda3 5234 12852 61192552 83 Linux /dev/sda4 12852 19458 53062657 5 Extended /dev/sda5 12852 19182 50847744 83 Linux /dev/sda6 19182 19458 2213888 82 Linux swap / Solaris i dont know which of sda1, ..., sda 6 etc ubuntu 8 is on. how can i find that out? The actual task is that i think a lot of space is devoted to ubuntu 8, if there is no easy way to get rid of it, then i want to repartition the disk so that about 50 GB of hard disk space is given to ubuntu 10's home folder from the ubuntu 8's home folder. but i hope that there is an easy way to get rid of ubuntu 8 alrogether and just have ubuntu 10 on my system.

  • Configure Domino to use SMTP routing and hMailServer

    - by Sébastien Lachance
    I have been trying for a couple of days to set up a Domino 8.5 server. Basically, I want everything to be run inside a local network. Right now I can send email to other user in the Domino directory without any mail address. I am pretty new to all this stuff, so maybe the answer will be really obvious. What I need to do is be able to send a mail from somewhere else to a domino user that will be redirected to his account. On the Domino server, I also have hMailServer installed on port 25. I configured Domino to use port 26. I followed those step to get where I am now. -I have set the Fully qualified Internet host name to "preview.notes". -Smtp Listener task changed to Enabled to turn on the Listener so that the server can receive messages routed via SMTP routing -Setting up SMTP routing within the local Internet domain (http://www.h2l.com/help/help85%5Fadmin.nsf/f4b82fbb75e942a6852566ac0037f284/7f9738a49efc4f58852574d500097b01?OpenDocument) -I modified the person to use the [email protected] address. -I'm using the hMailServer (which have the local "preview.local" domain name) to send mail to [email protected]. When sending mail I got an error telling that the DNS is not set up correctly. Is using the Domino Smtp server instead of hMailServer will solve the problem? I can Telnet the Domino Smtp Server.

  • Tooltips shadow stuck on desktop

    - by faulty
    I tends to get this problem from time to time. The tooltips with a shadow appearing on top of everything. It's the shadow of the tooltips not disappearing after the tooltips disappear. The last one I had the tooltips was from the wifi connection list at the systray. This problem also happen to me on another computer. Both running Win7 with ATI gpu. I found this similar post Menu command stuck on screen but none of the solution helped. In fact the "Fade or slide tooltips into view" has been unchecked from the beginning. Ending task of "dwm.exe" also doesn't help. So far the only way to resolve this by restarting window. I can't post picture yet, so can't show any screenshot. Edit: Just tested a few more trick which doesn't work. 1. Turn of aero 2. Hibernate 3. Switch main display to external display and switch back. 4. Change resolution

  • Is there a fix to display 0 when arithmetic underflow occurs on the Windows 7 calculator?

    - by Pascal Qyy
    I have a problem that exasperates me: When I take the Windows 7 calculator in standard mode, if I do 4, then v (square root), the result is 2 Fine. But, at this point, if I do - (minus), then 2, the result is -1,068281969439142e-19 instead of 0! OK, I know about ? (machine epsilon), and yes, -1,068281969439142e-19 is less than the 64 bits ? (1.11e-16), so, we have an arithmetic underflow, in other words in this case: 0. Great, my computer is able to represent subnormal numbers instead of just flush to zero when this happens, and it seems that it is an improvement! Subnormal values fill the underflow gap with values where the absolute distance between them are the same as for adjacent values just outside of the underflow gap. This is an improvement over the older practice to just have zero in the underflow gap, and where underflowing results were replaced by zero (flush to zero). BUT: this result is false! when you try to explain the concept of the square root to a child and you end up with this kind of result, it only complicates your task... what is the point to represent subnormal numbers in a standard, non scientific calculator? So, is there a way to fix this?

  • SQL 2000 Backup/Export Process - Can't find SQL 2000 Enterprise Manager, Can't use Mgmt Studio Expre

    - by 1nsane
    I need to make a backup of a client's SQL 2000 database, however there are a few issues preventing me from doing so using the traditional methods. I've tried using SQL Management Studio Express, but the host doesn't give sufficient privileges to create a backup and I'm getting some strange error messages. I've also tried doing the "Generate Scripts" to recreate the schema, then using the DTS Wizard to migrate the data, but the IDs set up with the identity specification property are not consistent with the live database once copied over. This results in some foreign key breakage... If I remember correctly, I was able to use Microsoft SQL 2000 Enterprise Manager to perform the task before, but I can't find this anywhere... it seems Microsoft has pulled most SQL Server 2000 stuff from their site. Does anyone know where I can find a copy of Enterprise Manager (or a trial of SQL Server 2000, which I believe comes with the component)? Or conversely, does anyone know of any other tools (preferably non-commercial) that are capable of mirroring remote SQL Server 2000 DBs? Thanks!

  • Adding network share as the system account breaks Win7 backup to network

    - by ChrisBenn
    (On Win7 Ultimate x64 SP1) So I've been using Win7 backup to \192.168.0.100\Backup\main-desktop\ for awhile without issue. Yesterday I tried to setup crashplan to synchronize my dropbox folder and a network share. I then found out that crashplan, as it runs under the system account, can't see my user mapped drives. So I created a startup script net use O: \192.168.0.100\Documents /USER:192.168.0.100\username password and set it to run, on startup, after the network interface is up, as the system account. (the username & password are the same for the net use script above, the locally logged in user, and the explicit username/password entered in windows backup). I woke up this morning to find error flags from the windows backup and get "Network location cannot be used" (0x800704B3). If I disable the startup task & reboot then windows backup works fine. I'm not sure why having a mapped drive for another user is killing windows backup (same server, different folder). I can work around the issue by using another program to synchronize the two folders, but I'm completely in the dark as to why this happens (and it's 100% repeatable). Uninstalling the crashplan client doesn't change anything - it's the net use run under the system account that breaks win7 backup (to a network location).

  • sql server 2008 cluster hang when a heavy load is run

    - by Billy OT
    we have a sql server 2008 active/active cluster running on wondows 2008R2 O/S. 14GB RAM, 4xCPU. we have set a ceiling of 12GB for sql server. We're running an agent job which loads 3 million records to a database. during this load the job fails and the cluster seems to attempt to fail over to the other node but unsuccessfully i.e., the cluster address is no longer accessible. we have to manually fail the cluster node back. during the load on viewing task manager we can see that memory usage hits a max of 12.5GB and CPU at times hits 100% on all 4 CPU, but for the most part fluctuates at an average of about 60%. I suppose my question is, will a cluster try to fail over if memory or CPU are taking a heavy hit? or am i barking up the wrong tree? also any ideas why it wouldn't fully fail over? we've crawled through logs, of which there are a lot, and can't find anything useful. we've also tried recreating the issue but it ran successfully at a later time. Also 3 million rows doesn't seem like a lot but in terms of resources should 14GB RAM and 4xCPU not be sufficient? Further information on this, we ran the load again today and corrupted the database! We received the error message : LogWriter: Operating system error 170. It looks like, under the heavy load, the sql cluster attempted to fail over and in doing so migrated a lun (or drive) which meant the disk was no longer reachable. (this is just our theory). The database is now 'suspect' and requiring restoration. The 170 error above also indicates that on failing over to the other node, the sql service could not start as it was already in use, therefore it couldn't fail over fully?? But I'm wondering why would it need to fail over in the first place? My assumptions could be completely wrong on this, so any ideas would be appreciated.

  • EC2 Configuration

    - by user123683
    I am trying to create a server structure for my EC2 account. The design I have chosen consists of 2 instances running in different availability zones, elastic load balancer, an auto-scaling group with cloudwatch monitoring configured and a security group defining rules for access to the instances. This setup is to support an online web application written in PHP. I am trying to decide what is a better policy: Store MySQL DB on a separate Instance Store MySQL DB on an attached EBS volume (from what i know auto-scaling will not replicate the attached EBS volume but will generate new instances from a chosen AMI - is this view correct?) Regards the AMI I plan to use a basic Amazon linux 64 bit AMI, and install bastille (maybe OSSEC) but I am looking to also use an encrypted file system. Are there any issues using an encrypted file system and communication between the DB and webapp i neeed to be aware of? Are there any comms issues using the encrypted filesystem on the instance housing the webapp I was going to launch a second instance or attach a second volume in the second availability zone to act as a standby for the database - I'm just looking for some suggestions about how to get the two DB's to talk - will this be a big task Regards updates for security is it best to create a recent snapshot and just relaunch and allow Amazon to install updates on launch or is the yum update mechanism a suitable alternative - is it better practice to relaunch instead of updates being installed which force a restart. I plan to create two AMI snapshots one for the app server and one for the DB each with the same security measures in place - is this a reasonable - I just figure it is a better policy than having additional applications that are unnecessary included in a AMI that I intend on using. My plan for backup is to create periodic snapshots of the webapp and DB instances (if I use an additional EBS volume instead of separate instances my understanding is that the EBS volume will persist in S3 storage in the event of an unexpected termination and I can create snapshots of the volume backup purposes). Thanks in advance for suggestions and advice. I am new to EC2 and I may have described unnecessary overkill but I want to try implement what can be considered a best practice solution so all advice is appreciated.

  • How to configure fastcgi to work with ligttpd in ubuntu

    - by michael
    I am able to run lighttpd on ubuntu 9.10. But when i tried to setup fastcgi with lighttpd by putting this in the ligttpd.conf file: #### fastcgi module fastcgi.server = ( "/fastcgi_scripts/" => (( "host" => "127.0.0.1", "port" => "9098", "check-local" => "disable", "bin-path" => "/usr/local/bin/cgi-fcgi", "docroot" => "/" # remote server may use # it's own docroot )) ) This is what I get in the error.log in ligttpd: 2010-03-07 21:00:11: (log.c.166) server started 2010-03-07 21:00:11: (mod_fastcgi.c.1104) the fastcgi-backend /usr/local/bin/cgi-fcgi failed to start: 2010-03-07 21:00:11: (mod_fastcgi.c.1108) child exited with status 1 /usr/local/bin/cgi-fcgi 2010-03-07 21:00:11: (mod_fastcgi.c.1111) If you're trying to run your app as a FastCGI backend, make sure you're using the FastCGI-enabled version.

  • SQL Server Management Studio not scripting all objects

    - by Ian Boyd
    i've been attempting to script a database using SQL Server 2005 Management Studio. i cannot get it to script some objects. It scripts others, but skips some. i can provide detailed screen shots the options being selected including all tables the folder where the script files will go the folder being empty before scripting the scripting process saying Sucess when scripting a table the destination folder no longer empty, with a hundred or so script files the script of some tables not being in the folder. And earlier SSMS would not script some views. Is this a known thing that the the Generate Scripts task does not generate scripts? Update Known issue on Microsoft Connect, but Microsoft couldn't repro the steps, so they closed closed the ticket. Fails on SQL Server 2005, also fails on SQL Server 2008. Update Two Some basic questions: 1.What version of SQL Server? Microsoft SQL Server 2000 - 8.00.194 (Intel X86) Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Microsoft SQL Server 2008 - 10.0.2531.0 (Intel X86) Microsoft SQL Server 2005 Management Studio: 9.00.4035.00 Microsoft SQL Server 2008 Management Studio: 10.0.1600.22 2.What O/S are you running on? Windows Server 2000 Windows Server 2003 Windows Server 2008 3.How are you logging in to SQL server? sa/password Trusted authentication 4.Have you verified your account has full access to all objects? Yes, i have access to all objects. 5.Can you use the objects that fail to script? (eg: select top(10) * from nonScriptingTable) Yes, all objects work fine. SQL Server Enterprise Manager can script the objects fine. Update Three They fail no matter what version of SQL Server you script against. It wasn't a problem in Enterprise Manager: Client Tools SQL Server 2000 SQL Server 2005 SQL Server 2008 ============ =============== =============== =============== 2000 Yes n/a n/a 2005 No No No 2008 No No No Update Four No errors found in the database using: DBCC CHECKDB go DBCC CHECKCONSTRAINTS go DBCC CHECKFILEGROUP go DBCC CHECKIDENT go DBCC CHECKCATALOG go EXECUTE sp_msforeachtable 'DBCC CHECKTABLE (''?'')' Honk if you hate SSMS.

  • New Windows Server 2008 R2 WIMP running slower than Windows Server 2003

    - by starshine531
    We recently upgraded a WIMP server from Windows Server 2003 (32 bit) to Windows Server 2008 R2 (64 bit). The new server has significantly better hardware than the old server, yet many processes take much longer than the old box. We have a rather complex web application process that normally takes about 7 seconds on the old box, but on the new one it takes 11-12 seconds. That's down from 15.5 seconds it took before I disabled IPV6. This process involves some queries (some of them involve transactions with maybe 3 queries between the start and commit) and creating and emailing some pdfs. Windows updates are current with a more or less fresh machine. This happens consistently even when we have almost no traffic on the site and memory and cpu aren't being hard pressed at all. The only differences between the servers other than the OS and hardware: 1) When available, we used 64 bit versions of programs 2) The new server uses MySQL 5.5 rather than MySQL 5.1 (I did run the mysql_upgrade program and we use InnoDB for the engine) 3) The new server uses PHP Version 5.3.18 rather than PHP Version 5.3.1 4) With the new OS came IIS7 rather than IIS6 of course. What could be causing better hardware to run so much slower? Let me know if you need more details. Thank you.

  • mysql is not connecting after data directory change

  • On dual boot system, Is it possible to use VirtualBox to boot other installed OS?

    - by Derek Ziemba
    I currently run Windows 7 from a 256GB SSD as my Operating System. Lately, for school, I've been using openSUSE linux inside a VirtualBox PC and I'm really liking it. I'm starting to hate even working in Windows. But I can't just abandon Windows. I've been considering dual booting openSUSE and will likely purchase another SSD for openSUSE. Once I have the dual boot set-up, there is going to be times I need to do something quick in the operating system that I'm not currently in. It would be a pain to have to reboot the computer each time I need to switch the OS for a simple task, especially from Windows since it doesn't let you save it's state. From openSUSE, I want to be able to start a VirtualBox Machine using my Windows Drive. And in Windows, I want to be able to start a VirtualBox Machine of my openSUSE Drive. Would this be possible? The issue I'm worried about is drivers. For instance, the OS will be installed on native hardware and have the native hardware's drivers configured. When I try to boot the OS in a VirtualMachine, I feel like the OS is not going to know what to do, and have to reconfigure itself or just not work.
