• How to Re-install an App that Shows up in the Appstore as 'Update' Instead of 'Buy App'

  - by Craig Reville

  So long story short: I dropped the wrong app into 'clean my mac' and I hit 'cancel' but it was too late by that point. I rebooted and appstore said it had an update, when I opened appstore it was showing an update for the app I just uninstalled. I tried clicking 'update' but it gives me an error saying it's unable to install after 'downloading'. When I try to go into 'purchased apps' it shows the app as uninstalled so I click 'install' and I get an error saying it's already installed. I'm running Lion OS X, latest version, updated, mac book pro is only a few months old. I tried searching through the entire system to remove all traces of the app, after rebooting appstore no longer shows the app and no longer shows the update but on the apps page it still says 'Update'. I tried reinstalling the app from desktop OUT of the appstore and again says the app is 'already installed'. So after reading more about lion I found an article that spoke about 'BundleID' being the thing that tells appstore what's installed and needing updating however I can't find the location of where the BundleID would be. Any thoughts? I've tried CCleaner, AppCleaner etc and none of them show the app, mainly because it is uninstalled. Update I've spoken to Apple Support who confirmed that there is a file in the system that connects separately to tell the system if there are updates available however they declined to inform me of any further details. Apple also referred me from technical support to iTunes App Store opposed to Mac App Store support and from there I have been referred to AppleCare who are currently 'investigating' this issue. Hopefully there will be a fix that's simple to implement for people having similar issues, this appears to be a more common issue than I previously thought.

• Can't get past bootcamp Windows logo, freezes immediately after picking boot partition -- Windows 7

  - by cksubs

  Hi, I had a fine install of Windows 7 alongside Snow Leopard. I had a power outage, and Windows restarted. When I booted via the "Hold Option" sceen, it started hanging at the grayscale "Windows logo" (squares) that comes up after picking the Windows drive from the bootcamp loader (the Windows version of the grayscale Apple logo when OS X loads). I think this happened once before, and installing rEFIt helped. I did that, but it continued to hang at the same point. I finally got fed up with it and erased the Windows partition via Disk Utility. I then reinstalled Windows 7 x64 from DVD to the fresh partition. Seemed fine. Ran Windows Update then restarted. FFFFFFFFF. Hangs in the same place. What can I do? Like I said, I already have rEFIt installed. Booting the Windows 7 install CD results in the same infinite loading error. I don't have a spare Snow Leopard disk handy.

• WebHost Manager - Apache's VHost isn't matching the DNS entry

  - by Trans

  I've used CPanel's WebHost Manager to create a new host on my VPS. I then used my HOSTS file to point fake.com to the relevant IP address. The problem I'm having now is, Apache isn't recognizing the VHost,or something, as it's just loading the default entry and 404'ing every document I try to GET. Here's the VHost entry NameVirtualHost 0.0.0.209:80 NameVirtualHost 0.0.0.211:80 <VirtualHost 0.0.0.209:80> ServerName fake.com ServerAlias www.fake.com DocumentRoot /home/fakecom/public_html ServerAdmin [email protected] ## User fakecom # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup fakecom fakecom </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup fakecom fakecom </IfModule> CustomLog /usr/local/apache/domlogs/fake.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." CustomLog /usr/local/apache/domlogs/fake.com combined Options -ExecCGI -Includes RemoveHandler cgi-script .cgi .pl .plx .ppl .perl ScriptAlias /cgi-bin/ /home/fakecom/public_html/cgi-bin/ </VirtualHost> I've Google'd this profusely and all that's being returned is 'DNS errors. Wait for it to propagate'. That's obviously not my problem, since I'm using HOSTS. What else could be causing this? :/ EDIT: Forgot to mention. http://fake.com/~fakecom/test.html loads just fine. So the fake.com is pointing to the right IP.

• IPv6 - Public IPs, private IPs, IPs derived from the MAC address? Confused!

  - by sinni800

  I'm pretty much excited for IPv6 because of the large address room and (potential?) owning of more than one IP, or even tens of IPs (/122 subnet?) Though one magazine has now confused me. In a current issue (no. 3) of "CT", a German computer magazine, I read that when using IPv6 your IP address consists of your MAC address and various other things, and that this address will be public on the web, no matter what access point / LAN you connect to. My knowledge of IP(v6) is in contrary of this. I thought you will normally always have a a local network IP and NAT takes care of your Internet access, and your provider gives the NAT router an IP. I've heard of the 6to4 interface, but does this one give you your own ip in the IPv6 net? Personally I hope it still is through a personal IP space (like 192.168, 127.16-31, 10. in IPv4) in private networks with a NAT going to the Internet. And also I hope that providers will offer subnets to private customers so they don't have to use NAT anymore. Yay for converting your LAN into the WAN and using better security (so Computers from the same subnet still get access rights like normal).

• Setting up port forwarding for web server

  - by reyjavikvi

  This could belong on Super User, but I thought this place was more appropiate. I want to run Apache in my computer and want to make it available to the outside world to test a couple things. Apparently, I have to go into my router's (a TP-LINK TD 8910G) settings and forward port 80 to my PC's IP. So far so good. Thing is, since the router uses a web based interface and it's kind of stupid, it told me that since I was using port 80 for this, I should access its settings through port 8080. Maybe it can't detect requests coming from the LAN, I don't know. Point is, now neither port can't access the configuration, and I can't access Internet. Specifically, trying to access anything (including 192.168.1.1, the router's settings) through port 80 turns up a blank page (maybe if I had the server running in my computer I'd get something, but I don't want to risk trying, I had to reset the router and restore the settings), and port 8080 gives a "Can't establish connection" error in Firefox (and similar ones in other browsers). Is there a way to configure the router to not redirect requests coming from inside the network? I'm a beginner with this stuff, so please try to explain in a simple way. If this is more appropiate in Super User, I'm sorry.

• Removing resource limits on Solaris 10

  - by mikeydonkey

  How should one remove all potential artificial resource limitations for a process? I just saw a case where a server application consumed resources so that some limitation was hit. The other shells into the same server etc were all extremely slow (waiting for something to free up for them; ie. prstat starting 5 minutes). It wasn't CPU/memory related problem so I think it has got something to do with ulimits / projects. Already managed to set the maximum open files to 500 000 and it helped a little bit. However there is something else and I can not figure out what resource is maxed out. I can get some in-house administrator probably to check this but I would like to understand how I could make sure there shouldn't be any limitations! If you think I am going the wrong way (would be better to figure out what limitation should be specfically tuned etc) please feel free to point me to the correct way. I know technical stuff - it's just Solaris 10 that is giving me headache :/

• Write permissions on uploaded files - PHP & Linux

  - by letseatfood

  I am working on a PHP script that transfers files using FTP functions. It has always worked on my production server (which is a hosting service). The development server I have just setup (I am a novice to servers) is Debian Lenny with Apache2, PHP5, and MySQL5. The file transfer works correctly, but once the file has been written to the server, it has permissions of 600. This makes it impossible for me to view the file (JPEG) in the web browser, as permission is denied. I have scoured the internet and even broken my server installation and reinstalled it trying to figure this out (which has been fun, nonetheless!). I know it is unwise to set 777 permissions on public accessible files, but even that will not solve the problem. The only thing that works is if I chmod 777 thefile.jpg after it has been transferred, which is not a working solution. I tried changing the owner of my site files to www-data per this post, but that also does not work. My user is mike, and it still does not work whether the owner of the files is mike or root. Would somebody point me in the right direction? Thanks! And, of course, let me know if I can clarify anything.

• Do I need to restart my server after editing fstab and mtab?

  - by jaypabs

  I'm just wondering if I need to restart my server after editing fstab and mtab. I changed something in this file manually due to problem with awstats report. I am using ISPConfig 3 with the help of the tutorial from howtoforge. But due to removing/deleting of some account, the configuration of fstab and mtab messed up. I also ask this question at howtoforge forum but until now no one has answered. If you'd like to read my question please visit it here. I tried very hard to fix the problem w/o luck. Update: Here's what happen to my fstab: Before the value was (I omitted the other): /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web1/log none bind,nobootwait 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web2/log none bind,nobootwait 0 0 So I changed it to the correct path: /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web2/log none bind,nobootwait 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web3/log none bind,nobootwait 0 0 I also found mtab to have the same value as above that's why I edited it manually. from: /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web1/log none rw,bind 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web2/log none rw,bind 0 0 to: /var/log/ispconfig/httpd/mydomain.com /var/www/clients/client1/web2/log none rw,bind 0 0 /var/log/ispconfig/httpd/example.com /var/www/clients/client1/web3/log none rw,bind 0 0 I edited those value because the correct path of mydomain.com and example.com should be under web2 and web3 folder respectively. As of now the log of example.com is pointed to: /var/www/clients/client1/web2/log when it should be: /var/www/clients/client1/web3/log So I am thinking that this is because of fstab and mtab. Please guide me how to point the log correctly to it's default directory. I explain the scenario one by one at this link. to dawud: Based on your example mount -o remount,noexec /var, should I run mount -o remount,noexec /var/log/ispconfig/httpd/example.com?

• Google app mail hosting and windows 2008 server DNS configuration

  - by fyasar

  Hi There, I used to use shared hosting before and I created a google app account and I configured DNS records on shared hosting's contol panel according to google dns documentations. Everything was working until I switched to dedicated server. First I added DNS role to my new server and I configured whole DNS and NS stuff. I have mail address that mail.domain.com that was redirecting to google app email before. Rightnow, It's not possible to access to mail.domain.com addres from somewhere. But I'm accessing from a few point which located some computer on different network. I stacked in this problem. Please, see the below screen shots I checked on DNSStuff.com,everything is green. Also, I checked on InteliWiz, it seems correct And, Here is the my DNS records. I was accessing to my mail.domain.com address from everywhere, Now, I cannot access to mails from many places since 3 week. Where is the my mistake ? Any help would be appriciated.

• Why Is Volume Shadow Copy Services stopping?

  - by David Mackintosh

  I am running Windows 7 Professional, 64-bit. I am running a backup-over-the-internet software client which depends on the Volume Shadow Copy Services running. Since I installed Service Pack 1 (or rather, didn't object when Windows Update forced Service Pack 1 on me) the backup service is failing to back everything up because VSC isn't running. Most of the time it fails to back up such noise as the Security Essentials database or the Messenger Live contact list -- stuff I really don't care about -- but I don't want to fall into the trap of accepting an Error-state backup as "normal". At the recommendation of the backup software, I have set the VSC service startup mode to be Automatic. When I look in the Event Log, System channel I can see at boot time: The Volume Shadow Copy service entered the running state. ...and then two or three minutes later: The Volume Shadow Copy service entered the stopped state. How do I figure out why VSC is stopping? At the suggestion of the backup vendor, I have already followed the suggestions from http://support.microsoft.com/default.aspx/kb/940184 net stop SENS net stop EventSystem net start EventSystem net start SENS net stop COMSysApp net stop SwPrv net stop VSS cd /d C:\Windows\system32 regsvr32 ole32.dll /s regsvr32 oleaut32.dll /s regsvr32 vss_ps.dll /s vssvc /register /s regsvr32 /i swprv.dll /s regsvr32 /i eventcls.dll /s regsvr32 es.dll /s regsvr32 stdprov.dll /s regsvr32 vssui.dll /s regsvr32 msxml.dll /s regsvr32 msxml3.dll /s regsvr32 msxml4.dll /s net start SwPrv net start VSS net start ProtectedStorage ...and per http://support.microsoft.com/kb/940184 I have deleted the key tree HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions I have also run chkdsk /F and chkdsk /R on both permanent hard disks. (I had a similar problem with another computer (same OS, same failure, same start point after SP1 install) but the problem went away when I forced Volume Shadow Copy Services to Automatic startup rather than Manual. I did not have to resort to following the Microsoft KB instructions.)

• SMTP server closes connection unexpectedly

  - by janin

  I'm writing a python program to send emails, and when trying to send to yopmail, hotmail and some other hosts the connection gets closed by the server without a message. I tried connecting directly with netcat and the same thing happens. Here's what the exchange looks like : $ nc smtp.yopmail.com 25 220 mx.yopmail.com ESMTP *** ehlo mx.myhost.com 250 SIZE 2048000 mail FROM:<[email protected]> 250 OK rcpt TO:<[email protected]> The connection is just closed abruptly at this point. On other hosts, like my ISP's, everything goes fine. I've checked the blacklists but my IP is not listed. Any idea what's going on? Edit: My IP is not listed in any blacklist. I own myhost.com, but I don't have an SPF record. I'll add one and update this post when the record has propagated. Edit 2: with the SPF added the email is now accepted and Hotmail adds a Authentication-Results: hotmail.com; sender-id=pass header to the email. However it gets classified as spam, but I guess that's another matter. Thanks for your help.

• Using WebDAV for automated downloads

  - by Geo Ego

  I currently manage a number of sites (at one point about a dozen, currently four, but soon growing into the dozens or hundreds) that serve a piece of software to clients at their remote locations. Our web server is Windows SBS Server 2k3, and the remote servers are Windows Server 2k3.When we have new versions of the software, I upload this new software to a specific directory and rename it; each time the clients boot, they pull their software from that specific directory. With just a few sites, it's no problem for me to RDP in and copy the files over. As the number grows, this will quickly become quite unwieldy. So I'm thinking that WebDAV would be part of a solution, so that I could simply push the newest version to our server (Windows SBS Server 2003) and make it available to the sites to grab. However, on the remote server side, what are some suggestions for automating the download? I only want the servers to download the files during downtime (between 3 AM and 9 AM), and I only want them to download if there is a new version available. I had thought of writing a program that checked the files on the WebDAV server at a regular interval, compared a hash of the current software to a hash of the software on the server, and only downloaded if they were different, but I'm wondering if there is something I am unaware of that can automate the process.

• Windows Domain Chaos - Any Solving Approach

  - by Chake

  we are running an old Window 2003 Server as Domain Controller (DC2003). To safely migrate to Windows 2008 R2 we added a 2008 R2 (DC2008R2) to the domain as domain controller (adprep etc.). After dcpromo on DC2008R2 everything seemed to be ok. The new DC appeared under the "Domain Controlelrs" node. It wasn't checked at this time, if DC2008R2 can REALLY act as domain controller. Later we tried to shutdown DC2003 and ran into a total mess with non functional Exchange and Team Foundation Services. After that I got the job to fix... First i thought it could be an Problem with DC2008R2. So I removed it as Domain Controller and installed a new Windows 2008 R8 Server DC2008R2-2. I ran into similar Problems. I tried a bunch of stuff, but nothign helped. I won't list it, maybe I made an mistake, so I'm willing to redo it with your suggestions. To have a starting point I tried the best practise analyser whicht ended up with 24 "Compatible" and 26 "Not Compatible" tests. From these 26 tests 19 read the same. (I'm translating from german, so that may to be the exact wording) Problem: Using the Best Practise Analyser for Active Directory Domain Services (Active Directory Domain Services Best Practices Analyzer, AD DS BPA) no data can be be gathered using the name of the forest and the domain controller DC2008R2-2. I appreciate any suggestions, this really bothers me.

• Samsung laptop randomly shuts down

  - by Dmatig

  I've rewritten this question because it turned into an indecipherable mess. I have a Samsung R560 laptop that is overheating, and shutting itself down under load consistantly. Thank you quickcel for reccomending me Speedfan to monitor my temps. Here they are (Load / Idle): (Ignore "Temp1 and Temp2", whatever sensors they are they'd always random, pretty sure they're broke). The load temperature is after just 5 minites of playing Fallout 3 - another 5 minutes and it (the GPU - 9600M GS) consistantly breaches the mid 90's then shuts down, so it's hard to get a good picture of it. I'm looking for some solution or way to decrease these temperatures, because they seem far too high even idle. I've tried: Opening up the case and clearing of all dust with compressed air. Updating drivers for my Graphics card Have purchased and am using a notebook cooler I don't want to: Undervolt / underclock (defeats the point of having a more expensive card) Use lower power / performance settings (again, i might as well have bought something cheaper) Is there anything else i can try (software or inexpensive hardware) that can help me fix this? Has anybody had a Samsung laptop and knows if this can be sorted under my warranty, and the turnaround time of sending it off (UK?)(it has always ran hotter than it should, but now at 6 months old is getting hot enough to power off)

• How to set up RAID-0 first time on new PC?

  - by jasondavis

  I have built basic PC's in the past but have never used a RAID array at all. SO now I am buying parts to build my new PC, it will be an intel i7 processor. My motherboard will have RAID support which I will use instead of an aftermarket raid controller for now. Also I plan to use 2 SSD drives in RAID-0 for my windows 7 OS. (Please note that I am aware of the issues with doing this, including lack of TRIM support when using RAID with SSD drives. I am OK with it not working as I can just re[place the drives in a year or so or wheneer they become more sluggish). SO here is my question part. If I assemble the motherboard, PSU, processor, RAM, vidm card, etc and then go to turn the PC on, it will have the 2 SSD drives hooked up. so I assume I will then soon the BIOS screen before I install windows? How to I go about making the 2 drives work in RAID-0 at this point? I do the raid part before installing my OS right? Please help with the steps involved from assembling the parts of the PC and then turning it on, to the part of getting the RAID-0 set up between the 2 drives and then installing my windows 7 OS from a Optical drive? Please help, all advice, instructions, tips appreciated as long as on topic. I do not need to be told that this is a bad idea as far as if 1 drive fails I losse it all, I plan on having a disk IMAGE to be able to restore my OS and software to a new set of drives at anytime needed in the event of drive failure. Same goes for lack of TRIM support. Thanks for reading and help =)

• Copy one db diagram from one db to another on different servers? (Same db)

  - by sah302

  I used the copy database wizard to copy my database from our test server to our production server, the database copied everything fine except for the diagram. Okay no problem, first I make sure the target database on production has the support objects created to use database diagraming. Then I select to import data from the other database and chose the dbo.sysdiagrams.Go through with the rest of the import data wizard, but then I get the following error: Validating (Error) Messages Error 0xc0202049: Data Flow Task: Failure inserting into the read-only column "diagram_id". (SQL Server Import and Export Wizard) Error 0xc0202045: Data Flow Task: Column metadata validation failed.

(SQL Server Import and Export Wizard) Error 0xc0024107: Data Flow Task: There were errors during task validation. (SQL Server Import and Export Wizard) So apparently it didn't like that. What's the problem? I am pretty beginner in SQL Server and only do stuff via the GUI usually so am not sure what to do at this point. The databases are the same, but on different servers. Thanks!

• KVM error with device pass through

  - by javano

  I am running the following command booting a Debian live CD passing a host PCI device to the guest as a test and KVM errors out; kvm -m 512 -boot c -net none -hda /media/AA502592502565F3/debian.iso -device pci-assign,host=07:00.0 PCI region 1 at address 0xf7920000 has size 0x80, which is not a multiple of 4K. You might experience some performance hit due to that. No IOMMU found. Unable to assign device "(null)" kvm: -device pci-assign,host=07:00.0: Device 'pci-assign' could not be initialized lspci | grep 07 07:00.0 Ethernet controller: 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 74) I shoved an old spare NIC into my motherboard to test PCI pass through. I have searched the Internet with Goolge and found that errors relating to "No IOMMU found" often mean the PCI device is not supported by KVM. Does KVM have to support the device being "passed-through"? I though the point was to pass the device through and let the guest worry about it? Ultimately I want to pass-through a PCI random number generator, is this not going to be possible with KVM? Thank you.

• ASP.NET Session State SQL Server 2008 R2 Freezes with High CPU Usage

  - by jtseng

  Our ASP.Net website uses SQL Server as the session state provider. We currently host the database on SQL Server 2005 since it does not play well on 2008 R2. We would like to know why, and how to fix it. hardware setup Our current session state server has SQL Server 2005 with the files hosted on a single local disk. It is one of our oldest servers since it has served us well, and we never felt the need to upgrade it. The database is about 2 GB holding 6000 sessions. (The sessions are a little big, but we need it.) We have another server with SQL Server 2008 R2 with a much faster CPU, much more RAM, and a much faster hard disk. situation One day, we have a huge surge in traffic. The transaction log growth on SQL Server freezes the server for 10's of seconds, allowing only a few requests through in minutes. So we load up the new server with ASPState with very large data and log files and point all of our applications to the new server. It chugs along fine for about 5 minutes, and then the CPU usage jumps up to 50% of the 16 cores that Standard Edition can use and freezes for 10's of seconds at a time. The files do not record any autogrowth events. The disk queue is nice and low. RAM usage is low. CPU usage on our old server has never been higher than 5%. What happened on the new server? Alternatively, I would like to hear success stories with ASP.NET session state server running on SQL Server 2008 R2 with an average write load of 30MB/sec with bursts up to 200MB/sec.

• Pin the Dock to the top or disable it

  - by Chris Buchholz

  I wonder if it is possible to pin the Mac OS X Dock to the top in Snow Leopard? I see lets of ideas on how to do this when I google for it, and Secrets (the tweaking app) also provide it as an option, but I don't see any of the ways working for me. I guess it must have worked at some point, since people said it did, but I believe this feature might have been removed from Snow Leopard, and therefore does not work for me. Is this so? Is there really no way to pin the Dock to the top of screen? If not, what ways of "getting rid of the dock" can you guys recommend? I have tried with auto-hiding, but my problem is that this will leave a 4px line at the edge of where the Dock is pinned to, that applications wont cover. Thats not ideal for me. As far as I have understood from googling, this line will not appear if the Dock is pinned to the top, hence my question. What other ways do you guys use to get rid of it?

• Recommendation for robust, customizable, open source, Java servlet-based forum software?

  - by Erik Hermansen

  There is a lot of forum software out there, but it seems to me that a lot of the popular choices are PHP-based. And for my project, I'd like something based on Java servlets so my team can make customizations to it. Another important feature is that I can completely change the pages to hide unwanted elements without too much work. So I'm looking either for a template system or easily editable scripts (i.e. JSPs) that have a clean view separation. Just having skin changes or CSS customization is not enough. I understand that if I have open source, I can change anything I want, but my point is that it should be easy and not requiring mastery of a complex code base. Finally, I want something that has been around for at least a year and deployed on some high-traffic sites. Clustering support (one database, multiple web servers) is highly desirable. Up-time is crucial since I have an SLA to support. What do you think?

• EngineX ignores Auth Basic?

  - by Miko

  I have configured nginx to password protect a directory using auth_basic. The password prompt comes up and the login works fine. However... if I refuse to type in my credentials, and instead hit escape multiple times in a row, the page will eventually load w/o CSS and images. In other words, continuously telling the login prompt to go away will at some point allow the page to load anyway. Is this an issue with nginx, or my configuration? Here is my virtual host: 31 server { 32 server_name sub.domain.com; 33 root /www/sub.domain.com/; 34 35 location / { 36 index index.php index.html; 37 root /www/sub.domain.com; 38 auth_basic "Restricted"; 39 auth_basic_user_file /www/auth/sub.domain.com; 40 error_page 404 = /www/404.php; 41 } 42 43 location ~ \.php$ { 44 include /usr/local/nginx/conf/fastcgi_params; 45 } 46 } My server runs CentOS + nginx + php-fpm + xcache + mysql

• Adding a Printer to my Print Server Failing

  - by Rudi Kershaw

  So, on the Windows Server page I read the following. Step 4: Add Network Printers Automatically Print Management (Printmanagement.msc) can automatically detect all the printers that are located on the same subnet as the computer on which you are running Print Management, install the appropriate printer drivers, set up the queues, and share the printers. To automatically add network printers to a printer server Open the Administrative Tools folder, and then double-click Print Management. In the Printer Management tree, right-click the appropriate server, and then click Add Printer. On the Printer Installation page of the Network Printer Installation Wizard, click Search the network for printers, and then click Next. If prompted, specify which driver to install for the printer. So, I have got to this point, made sure the printer (Canon MP620) is on and correctly plugged into the network. However, when I click "Search the network for printers", the wizard doesn't find it. Now, I can't get any further. Is there anything I could be doing wrong? How should I proceed moving forwards?

• SQL Server Offsite Backups

  We have about !TB of SQL Server databases, and these databases generate about 200GB of data changes each day. Up to this point we have been doing Weekly full backups, daily diff backups, and hourly transaction log backups. The full and diff backups are backed up to tape and taken offsite each day. We have been trying to move away from tapes, and our IT department purchased a Barracuda Backup device that backups up data and then sends it offsite using our internet connection. I have been trying to get this to work for our SQL Server backups, and have ran into a number of problems. I normally like to just use SQL Server to perform backups instead of trying to use a agent, so that is what I tried first. However the Barracuda device was not able to dedup these files very well, so it ended up being to much data to try to send offsite and to archive. I then tried installing the Barracuda agent and using it to backup the SQL Server databases. However the problem I am having there is that on some of the database servers I also have files that need backed up, and I cannot find a way to create seperate backup schedules for the file backups and the SQL Server backups. Barracuda only does full or transaction log backups. So if I want to do hourly transaction log backups I end up doing a file system backup every hour (which is not good), or if I only schedule the backups to run once a night I either have to do a full backup every night, or only do a transaction backup once a day. None of these scenarios are good options. My question is, how is everyone else getting their large SQL Server database backups offsite. Are you just using tape, or have you found a offsite backup device that works well? Is anybody else using Barracuda to backup their SQL Server databases? If you do, then how do you have it setup?

• Designing a software based load balancer

  - by Kishore pandey

  Hello to all Server fault users, I am new to this website but have constantly been using the mother website, stackover flow. Well to begin with, i would like to design a load balancer for the organization i am working for. As i am very new to this whole, idea about load balancing and networks. I am finding it very difficult to start my project. I did a lot of research on already existing load balancer and found some(HAPROXY,NGINX) that could solve my problems, but the point is, I am still in a dilemma if they could answer the following requirements of mine: The client and server in my architecture are distributed. The load balancer should take care of the firewall. LB server should balance the load among all servers present in WWW cloud. The LB server should have some sort of configuration file, with the help of which it is possible to configure the servers. Heart beat: With the help of which it would be possible to check if any server is down, if any server is down the request should be passed to some other server. Various load balancing algorithms of the incoming requests. Easy error handling. It should be fairly possible to prioritize the incoming requests. Is there any already available load balncer solution on the market that could satisfy these requirements? If not is there any base code available with the help of which i could develop my own load balncer. If not where should i start from scratch? I am practically new to everything. Any help from a load balancer expert is very much appreciated. Thanx a ton in advance. Cheers and regards. Kishore

• Can enabling a RAID controller's writeback cache harm overall performance?

  - by Nathan O'Sullivan

  I have an 8 drive RAID 10 setup connected to an Adaptec 5805Z, running Centos 5.5 and deadline scheduler. A basic dd read test shows 400mb/sec, and a basic dd write test shows about the same. When I run the two simultaneously, I see the read speed drop to ~5mb/sec while the write speed stays at more or less the same 400mb/sec. The output of iostat -x as you would expect, shows that very few read transactions are being executed while the disk is bombarded with writes. If i turn the controller's writeback cache off, I dont see a 50:50 split but I do see a marked improvement, somewhere around 100mb/s reads and 300mb/s writes. I've also found if I lower the nr_requests setting on the drive's queue (somewhere around 8 seems optimal) I can end up with 150mb/sec reads and 150mb/sec writes; ie. a reduction in total throughput but certainly more suitable for my workload. Is this a real phenomenon? Or is my synthetic test too simplistic? The reason this could happen seems clear enough, when the scheduler switches from reads to writes, it can run heaps of write requests because they all just land in the controllers cache but must be carried out at some point. I would guess the actual disk writes are occuring when the scheduler starts trying to perform reads again, resulting in very few read requests being executed. This seems a reasonable explanation, but it also seems like a massive drawback to using writeback cache on an system with non-trivial write loads. I've been searching for discussions around this all afternoon and found nothing. What am I missing?
