• Shared volume for data (multiple MDF) and another shared volume for logs (multiple LDF)

  - by hagensoft

  I have 3 instances of SQL Server 2008, each on different machines with multiple databases on each instance. I have 2 separate LUNS on my SAN for MDF and LDF files. The NDX and TempDB files run on the local drive on each machine. Is it O.K. for the 3 instances to share a same volume for the data files and another volume for the log files? I don't have thin provisioning on the SAN so I would like to not constaint disk space creating multiple volumes because I was adviced that I should create a volume (drive letter) for each instance, if not for each database. I am aware that I should split my logs and data files at least. No instance would share the actual database files, just the space on drive. Any help is appretiated.

• Vista to Vista network visability issue

  - by Sk93

  Hi All, I've got a Vista Business PC and a Vista Business Laptop connected via a virgin media router (Netgear CG2100D) and I cannot get the two machines to see each other correctly over the network. The laptop is connected via wireless, whilst the pc is wired. Both are set to recieve their network settings automatically (DHCP) and both have the windows firewall (the only firewall on either) turned off completely. I can ping each machine fine from one another using the ip addresses, and I can also connect via \. However, connections via \ fail, and I cannot see the machines in the network map. I have tried turning netBIOS to be "always on" on both adapters, but this makes no difference. I've been messing around pretty much for 6 hours now and am getting quite fustrated by this! (my original aim was to get media sharing working, but I've pretty much abandoned that for now). Any ideas?

• Why my browsers display XML files as blank pages?

  - by n1313

  Every time I open an XML file, all I get is blank page instead of tag tree. The file itself is correct and loads okay, I can see it via View Source or in the Firebug. I've tried turning off all my addons and tried running Firefox in safe mode, but the problem was not solved. I'm guessing that I've messed up my configuration somehow and Firefox now tries to render XML files as HTML ones. I've tried googling, but with no success. Help, please? UPD: example file: http://lj.lain.ru/3/1273657698603.sample.xml Also I've noticed that somehow all of the browsers on the machine are now acting the same, so I'm changing the question accordingly

• Unable to create a Windows 7 system image of a failing hard drive

  - by Rahul

  The hard disk of my one year old T400 Thinkpad has started failing periodic hardware tests. I get a "Targeted Read Test Failed" error. The "SMART short self test" times out. I am now trying to create a Windows 7 System image of the hard disk but it fails without giving any specific error messages. I tried using Comodo Backup but got an error (code 101117) there as well. I have copied the important files in Dropbox but would like to take a full System backup as I have plenty of software installed on the machine. Does anyone know why this is happening and how I can take a backup of the system image ?

• retransmission of lost TCP segment

  - by tcpip

  What will happen in the following scenario (assume the connection is already established): (stack A) send 10 byte data (stack B) send ACK for 10 byte data (stack B) send 200 byte data (stack B) send 100 byte data (stack B) send 50 byte data (stack A) send ACK for 350 byte data and also send 70 bytes data This segment gets lost and does not reach machine B. (stack B) retransmit 200 byte data (step 3) (stack A) send ACK for 200 byte data and the next expected seq number as the one for 70 bytes data Question: Should 70 bytes data be also transferred with the ACK in step 8? Note that the retransmission timer for step 6 has not expired yet.

• To Run Linux (Ubuntu) on Windows 7, is using Virtual PC one of the best ways?

  - by Jian Lin

  I need to try Linux (Ubuntu) and feel hesitant to install Ubuntu on top of a Win 7 machine to dual boot (might need to use Win7 and Ubuntu at the same time). Is creating a Virtual PC on Win7, and then installing the latest Ubuntu on that Virtual PC one of the better option? So I think I can create a Virtual PC with an empty virtual hard disk (vhd), say, for 30GB, and then put in the Ubuntu DVD-R or CD-R to install Ubuntu onto that empty hard disk. Update: for some reason, the first time Ubuntu 10.04 installation CD-R boots up, it asked for the Language, and "Install Ubuntu" and then the screen has vertical green bars and then the VPC just closed. The 2nd or 3rd time it booted up, there is no asking of Language or "Install Ubuntu" and just shut down the VPC, sometimes with vertical green bars. I even created another new hard drive and same thing happened. And created VPC 02, and same thing happened. Created VPC 03 with a fixed hard drive size of 60GB and same thing happened.

• Home Network Photo Server

  - by CMP

  I am looking for a photo solution for our home network. We have several computers, running windows and OS X. I would like to store all of our photos in a central location, and have them be accessible from any machine. Most of our photos are currently in an iPhoto library, and ideally there would still be a way to import photos from the server to iPhoto easily. This can run really on any operating system, but it must be easily accessible for anybody. A gallery type view would be good, but also must allow direct file access and transfers. Anybody have a solution that works for them, or any ideas of what I could do?

• Tracking down memory issues affecting a website

  - by gaoshan88

  I've got a website (Wordpress based) that became unresponsive. I SSH'd into the server and saw that we were out of memory. Errors in my apache log files indicated the same... things failing to be allocated due to lack of memory). Restarting the server fixes it. So I look in access.log and error.log around the time of the incident but I see nothing strange. No extra traffic, no unusual requests. In fact the only request around the time of the problem was one from Googlebot for an rss feed... at that point I start to see 500 response codes in the logs until the machine was rebooted. I look in message.log hoping to see something but there is nothing at all for that entire day (which is odd as there are entries for every other day). The site has a large amount of memory allocated to it and normally runs using about 30% of what is available. My question... how would you go about trying to track this down at this point? What are some other log files I could check or strategies I could take?

• Printing on Windows 8 64-Bit through Windows Server 2008 (32 Bit) RemoteApp

  - by Chris

  We have a network where our server is running on Windows Server 2008 (32 Bit) and a client computer is running on Windows 8.1 (64 bit) with a local printer attached to the client. The printer is an HP P1006. The remote app works well but when trying to print we get an odd "error 545". We have tried both using the "connect client printer" function in remoteapp and also making the printer shared over the network and printing to it via the network from within the remoteapp. Nothing works. We can print a test page from the server to the client computer just fine, but it seems from remoteapp we cannot. We have also tried installing the 32 bit drivers on the 64 bit machine as both the primary and secondary drivers but cannot get them to install. Suggestions please? We've been going crazy over this issue.

• Can a working Tomcat 6 webapp be turned into a usable .war file?

  - by Bill Cole

  Problem: I have a working webapp on a FreeBSD 8.1 Tomcat 6 test server that I need to move to a production system. The developer who last touched it (and had root on that server) has moved on and isn't helpful. The running app seems to have been deployed from a CVS server that is now unavailable. My thinking is that I would like to find a way to wrap the working webapp into a proper .war so that I can deploy it on a pristine host and (after testing) send the existing system to a very deep bitbucket. But I'm not having luck finding a way to do that. I'm a sysadmin not a developer and don't work much with Tomcat systems so I may be (likely am) overlooking something blindingly simple. I gather that I may be able to just tar up the deployed directory and untar it on the new machine, but I have a nagging feeling that there are pitfalls in that.

• Why can't I create a Windows backup on my secondary disk?

  - by Brian Sullivan

  I've installed Windows 7 Ultimate on an SSD that I've added to the XPS desktop that I bought from Dell. I would like to use the built-in backup functionality to create incremental backups and store them on the large drive that came with the machine. I formatted the large drive and turned it into a Basic disk. However, when I try to set the backup location to the large internal disk (E:\) in the "Set up backup" wizard, a get a message saying, "A system image cannot be saved on a drive that your computer boots from or that Windows is installed on." Windows is not installed on that disk. I even deleted the OEM partition that was on the disk, and removed it completely from the boot order in the BIOS. Any clue why Windows is griping at me about this?

• Auto-connect Bluetooth headphones in Windows 7 64bit

  - by CptSkippy

  I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?

• Entire filesystem restore from rdiff-backup snapshot

  - by atmosx

  I'm trying to make a complete system restore from an rdiff-backup. The cli for backing was: rdiff-backup --exclude-special-files --exclude /tmp --exclude /mnt --exclude /proc --exclude /sys / /mnt/backup/ebox/ I created a new partition mounted the partition at /mnt/gentoo and did: rdiff-backup -r /mnt/vol2 /mnt/gentoo However when I try to chroot to this system (following gentoo's manual, which means mounting /dev/ and /proc) I get the following error: chroot: failed to run command/bin/bash': No such file or directory` All this takes place on a Parallels (virtual machine) Debian installation. Any ideas on how to proceed in order to fully restore the system? Best Regards ps. /mnt/gentoo/bin/bash works fine if I execute it. All files and permissions are in place rdiff-backup seems to work just fine. However the system cannot neither boot (exits with kernel panic - cannot find init) or be chrooted.

• hardware: delay and distinct 'click' before hard drive access

  - by matt lohkamp

  I have a windows 7 box stashed away in my closet, containing (among other things) 2 big HDDs linked together as a mirrored volume - basically a super lazy NAS / media server. I've noticed that when that drive is accessed (whether locally, on the machine itself, or remotely, from another computer, or my xbox, for example) there's a noticeable pause, and then from the computer itself, a 'click!' noise, after which the drive is accessed; e.g. open \\computername\shared\, wait 2 seconds, hear 'click!' and then see files appear in windows explorer. Any ideas? Otherwise the drive preforms normally - is it a windows thing? a HDD-about-to-die thing? Or a "yeah that always happens, you've just never noticed it before" thing?

• changing filesystem format from jfx to ext4 without losing data

  - by A.Rashad

  I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux.

• How can I get the best performance for playing games?

  - by Oli

  I've been playing a couple of Wine-games today and decided to switch to metacity to see what the performance difference was like. If you've never done it before, you just run metacity --replace but don't do that if you use Unity! Anyway, surprise surprise it was like playing on a dedicated Windows gaming machine. Playing under metacity today was bliss. Much higher framerates and just a fluidity that you'd expect from a native game. I'm not sure I can go back. Switching to metacity is no hardship but I wonder if there's anything else in the WM landscape that I should try out. I'm essentially looking for suggestions for the best way to play games. Mix up WMs, dedicated X sessions, whatever... As long as it makes Wine games run faster. Small print One process per answer (eg: New X session + OpenBox) We should probably land on a benchmark so we can show percentage improvement over a stock Compiz desktop. I'm open to suggestions in the comments. If people could test it and submit their how much it improves things for them in the comments, that would give others a good idea of if it's worth the pain.

• Why am I getting 'undefined method' exceptions when executing 'run_list add', 'run_list remove' and 'rackspace server delete'?

  - by Peter Groves

  [Originally posted this to opscode forum, got no response] I’m testing out a free hosted chef-server account and multiple subcommands are failing with ‘Unexpected Errors’. Perhaps my version and the server version are incompatible? OS: Ubuntu 12.04LTS Local Chef: 10.12.0 (Installed through gem) Local Ruby: 1.8.7 Also, the workstation machine has been manually configured, but the client(s) I’ve been experimenting with are launched with the Rackspace plugin (using ‘knife rackspace server create…’) The problem commands seem to fail when talking to the host chef-server, however, before it ever tries to modify the client, so I don’t believe that’s where the problem exists. The virtual-servers that are launched by ‘knife rackspace server create’ are launched properly but then deleting them with knife fails. If I include a recipe in the run_list when I create the server, the recipe is properly added to the run_list. If I try to add it later or remove the one that there server was initialized with, those commands fail. Here is the output of a few relevant commands (with stacktraces): https://gist.github.com/7100ada3fd6690113697

• Is Lojack preinstalled on Dell's laptops?

  - by Blorgbeard

  I'm looking at buying a Dell Studio 15 or similar. Unfortunately, they all seem to come with Lojack software included and no option to take it out of the build. I really do not want this software installed on my laptop. It sounds really abusable, and hard to get rid of once installed - it hides in your BIOS and survives reinstalls, etc. Does anyone know whether Lojack comes preinstalled on this machine, or if they just ship you a disc, which could subsequently be broken in half and/or microwaved into submission?

• Internet problems

  - by dan

  I've got problems on my freshly installed windows Xp machine. I cannot connect to the internet and I've tried various 'solutions' provided to me by the help and support center. Surprisingly none of them worked... Anyways, I've got 3 pc's next to me sharing a lan which is connected to the internet though a modem. The computer I use right now uses windows xp aswell and runs without any problems. I've tried everything on not working computer. I've ran the connection wizard several times, but it's not working :( Also I've very little experience with this version of windows, so I'm sorry if the solution is obvious.

• Getting More Performance out of a MacBook Pro

  - by 5arx

  So I've got a mid-2009 MacBook Pro 13". Integrated GPU so not a games machine but fast enough for doing .Net development in VMs. I love the little thing and wanted to give it a Christmas present so thought I'd mod it up a bit and give it a boost. I'm thinking of swapping out the stock 5400rpm HD with a faster hybrid drive (has 4GB RAM and spins at 7200rpm) but was wondering if any of you had tried or knew of anything else I could change/upgrade/mod to squeeze more out of my laptop. Before you answer though, please be aware that I'm not sure I can run to putting in the 8GB of RAM Apple have suggested :-( Thanks in advance.

• How do I turn off caching in IIS7?

  - by jammus

  Hello. I'm developing an ASP classic site under Windows 7 (form a queue ladies). The problem is IIS seems to be heavily making use of its cache for both static and dynamic content which really conflicts with my 'make a small change, alt-tab, hit ctrl-F5' development style. Changes made to .asp files may take two or three refreshes to show up where as changes to .js files can take 20 times as many. How do I go about turning the caching off on my development machine? Cheers. in b4 stop using asp classic

• How to version large binary files?

  - by Walter White

  I run Windows XP inside a virtual machine for some tasks. I attempted to use git to version the image for virtual box; however, it is about 6GB after all the service packs. I only have 6GB of ram and git bombs out saying it is out of memory. I would basically like to have snapshots of Windows so that I can simply blow away an image and start anew when I want to. I like to have something I can rollback to in the event that an upgrade doesn't work so I would prefer to use version control or snapshots if the filesystem supports it. Any ideas on what tools I can use to do that?
