• SQL Server 2008 R2 100% availability

  - by Mark Henderson

  Is there any way to provide 100% uptime on SQL Server 2008 R2? From my experience, the downtimes for the different replication methods are: Log Shipping: Lots (for DR only) Mirroring w. NLB: ~ 45 seconds Clustering: ~ 5-15 seconds And all of these solutions involve all of the connections being dropped from the source, so if the downtime is too long or the app's gateway doesn't support reconnection in the middle of task, then you're out of luck. The only way I can think to get around this is to abstract the clustering a level (by virtualising and then enabling VMWare FT. Yuck. Good luck getting this to work on a quad-socket, 32-core system anyway.). Is there any other way of providing 100% uptime of SQL Server?

• sudoer scheme for a web developer that retains future control of a server?

  - by Tchalvak

  Background I have a server that I'm looking to set up, and provide access to another web developer. I don't want to put many constraints on him, though I wouldn't mind isolating the site that he'll be developing from others on the server that I will develop. The problem Mainly what I want is to make sure that I retain control over the server in the future. I want to reserve the ability to create/promote/demote and other administrative functions that don't deal with web software. If I make him an admin, he can sudo su - and become root and remove root control from me, for example. What is a good setup for the sudoers file so that he can do things like: *install software (through apt-get) restart apache access mysql configure mysql/apache reboot edit web development configuration type files in /etc * And can't do things like: take away other admin permissions change the root password have control over other security/administrative functions Example sudoer files that accomplish something like that could be useful, I'm sure that people have needed to do this before.

• Linux stretch cluster: MD replication, DRBD or Veritas?

  - by PieterB

  For the moment there's a lot of choices for setting up a Linux cluster. For cluster manager: you can use Red Hat Cluster manager, Pacemaker or Veritas Cluster Server. The first one has the most momentum, the second one comes by default with RH subscriptions and the last one is very expensive and has a very good reputation ;-) For storage: - You can replicate LUN's using software raid / md device - You can use the network using DRBD replication, which offers a bit more flexibility - You can use Veritas Storage Foundation technology to talk to your SANs replication technology. Anyone has any recommandations or experience with these technologies?

• Funky mail sorting and grouping in Outlook 2007

  - by laurie

  In outlook 2007 I group mails in a folder by subject with mails in each subject group sorted by Received date (newest to oldest) This works fine; I tick 'Subject' and 'Show in groups' in the context menu of the folder's table header. Life is good. But the subject groups in the mail folder are sorted alphabetically. I would like the group which has the newest mail to be the first group. Similar to how the arrange by 'Conversation' works Can this be done? I'm not averse to an add-in/macro type solution if anyone can point me at examples of implementing custom sorting in Outlook

• Is there a way to create a consistent snapshot/SnapMirror across multiple volumes?

  - by Tomer Gabel

  We use a NetApp FAS 6-series filer with an application that spans multiple volumes. For backup purposes I would like to create a consistent snapshot that spans these volumes at the same point in time (or at least with an extremely low delta); additionally, we'd like to to use SnapMirror to replace the production environment to test volumes. The problem is in creating a consistent snapshot/SnapMirror, since these commands are not transactional and do not take multiple parameters. I tried scripting consecutive "snap create" or "snapmirror resync" commands via SSH, but there's always a 0.5-2 second difference between each snapshot. It's currently "good enough", but I'm seriously concerned about the consistency impact with increased load (we're currently in pre-production). Has anyone managed to create a consistent snapshot that spans several volumes? How did you pull it off?

• Transfer files using ssh

  - by zozo

  Good day to all. I am using ssh (winSCP) to transfer some files from a server to my workstation. The problem is that at some files I get disconnected. Always same files. I am the owner of the directory so I guess the file permissions is not a problem. (Also I set the permissions to 777). Is there a size limit or something like that? Thank you for your time. Protocol is SFTP, server is 32bit machine. Files are 100MB tops. Added: Worked with filezilla using ftp. This temporarily fix the problem but is not exactly a solution since maybe next time I won't have root access to create a ftp account

• Can Windows tell me what is using my USB drive?

  - by PP

  Being the good citizen I am, I left-click on the "Safely Remove Hardware" icon in my taskbar, and select my USB drive to dismount. Then I get the message: Windows can't stop your 'Generic volume device because it is in use. Close any programs or windows that might be using the device, and then try again later. Of course, being the Operating System, it knows exactly what applications are using my device. So why won't it tell me? As usual, I always end my Vista questions with this plea: anyone know a Microsoft Engineer I can kick?

• courier-imap w mysql : share a folder between 2 virtual users on debian

  - by Michael

  Hi I have a working courier-imap server on my Debian Etch private server ; users are virtual, authentificatin goes through mysql. It's been working good for years. I would like to share an imap folder between 2 users. I thought I would just have to do something like this : cd path/to/mailusers/dir ln -s path/to/user1/maildir/.folder_to_be_synched path/to/user2/maildir/ After I entered the command, I found that user2 saw a new folder in its imap client, but the folder appeared empty. It is not a permission problem because all the virtual users have the same permissions on the file system. Any idea what I could do ? thanks

• Create an alias in Windows XP

  - by Lord Torgamus

  Back in school, I used to have a .login file along the lines of alias ll = ls -l alias dir = ls -Fhl alias web = cd ~/public/public_www/development ... I'd like to do that sort of thing with my XP box here at work, but most of the resources I've found online seem fairly complicated and heavy-duty. Is there a way to do this that doesn't involve mucking about in the registry or running a large batch file? EDIT: My original reason for asking this was that I only need the command line for one command in one specific folder, and I wanted to be able to get to that folder quickly when I launched the command line. But the accepted answer for this question is so good that I decided to ask about my original issue as a separate question here.

• Did Acronis True Image Home 2012 clone operation "lock" my BitLocker disk?

  - by Thomas Eyde

  After trying to clone my primary drive, which requires a reboot to proceed, BitLocker detected that the boot sector had changed and required the recovery keys. Not a good situation to be in on Sunday evening when it is your IT-department who hold the keys. After talking with the guys at IT, I have tree suspects on why BitLocker locked me out: The newly added, second hard drive in my machine. The changed boot-order in BIOS. The changes True Image did in order to do its things on boot. As an end-user, I should never have to end up in situations like these without any warning. I would like to know what really happened, so I can inform Acronis on how they can improve their product to avoid this situation in the future.

• mod_rewite Rule: root/? root/app/views/home/home.php

  - by Jonathon David Oates

  I am shocking at mod_rewite, here's the scenario: I need a rule that rewrites mydomain.com to mydomain.com/app/views/home/home.php. The rule, or set of rules rather, must also rewite mydomain.com/signin to mydomain.com/app/views/signin/signin.php, and work in a similar fashion for any subdirectory, for example: mydomain.com/subdir must redirect to mydomain.com/app/views/subdir/subdir.php. The rules must also work with or without the trailing slash, for example: ….com or ….com/. Thank you all, your help is much appreciated! If you could outline how and why your solution works or direct me to a good resource that explains it, I'd be exceptionally grateful! Edit: I have got a simple .htaccess file with this: Options +FollowSymLinks RewriteEngine On RewriteRule ^$ http://mydomain.local/~Jay/some_awesome_app/app/views/home/home.php This does the redirect but changes the URL in the address bar too! I've not got a trailing [R] flag so why would this be?

• How do you add more space to a Fedora (LVM) partition?

  - by Trevor Boyd Smith

  In a nutshell, i have a VM that ran out of space. I increased the size of the VM's harddrive to be 4 times bigger but the OS partition is still only using 1x the space. I need to change the LVM partition to take up the extra 4x space but I don't know how to extend the LVM partition. (NOTE: To make the screenshots given below I had to boot from a live-cd for gnome-partition-manager (aka gparted). Very unfortunately gparted is only able to "detect LVM" and can't do any LVM operations.) Here is what "gparted" shows. Please notice that the "resize" option is not available: The Problem: I can't find good directions<1 on how to grow the LVM partition via GUI or command-line! How do you grow a LVM partition that was created by the default Fedora install? If you are giving command line directions. Please explain what each line of commands does.

• Using Superuser paths for specific topics

  - by Stenemo

  I have a very specific question, which I have not been able to find the solution I want to search Superuser and other websites using Google, but I want to limit it to a specific subject (e.g. the R programming language). Using Superuser paths for specific topics like "site:http://superuser.com/questions/tagged/r" Does not work, as can be seen when comparing searching using full path compared to searching entire website with more specific question. Also note the first hit being one step in the direction i want, but since this path itself does not hold the questions in its path it does not solve my issue. There should however be a better way to do this, e.g. by having a very specific Google search tag for the R programming language, which would have to be either in the path, on the webpage, or tagged differently. Seeing as Superuser has a good tag system I am optimistic that this can be used to solve my question. Is there a solution to this that always works on Superuser and similar sites?

• Creating svn repo programmatically from a webpage and sudo

  - by Adriano Varoli Piazza

  We want to automate the creation of the svn repos and trac environments for new projects. Basically, this would mean creating a web script that got some info (like env and repo name, etc) from the user and then executed sudo -u svn svnadmin create /var/svn/<projectname> trac-admin /var/trac/sites/<projectname> initenv [... All extra params...] For the second command, this is simple, as it already runs as the www-data user, so I wouldn't have to use sudo. But for the first command, I'd have to use sudo and add www-data to the sudoers file. I was wondering if this is a good idea, and how to do it in that case. Reading the manpage has left me with more doubts than certainties about this. This webserver would only be accessible from our internal network, by the way. The OS is Ubuntu Server 10.04.

• What software supports full multisession CD burning on windows?

  - by dma_k

  I know, that beating Nero in this field is very difficult. I have looked through best software listed in wiki, also checked the related posts here and here: most of the software either allows you to create ISO image and/or burn the existing image. However I am interested in the following flow: Import previous session Add/rename/remove files and directories Burn new session UltraISO is very good in (1) and (2). But it cannot append a disk with new session. InfraRecorder/CDBurnerXP can do (1) (2) (3) but: InfraRecorder crashes when trying to import some Nero sessions CDBurnerXP does not allow to move files in previous session to another directories. Is anybody here happy with any other free software?

• Best copy and paste software for windows?

  - by jasondavis

  Sorry if this question exist already, I did some searches but could not find one myself. I am looking for the best programs to copy and paste stuff in windows more easily. So let's say instead of the default copy/paste one item at a time, I could have 5 different paragraphs that could all be pasted somewhere seperately. Hopefully this is not to confusing. Instead of bveing able to paste 1 item I would like to have a list of items that can be pasted or some similar functionality under windows. Please help make me more productive, I frequently need to copy and paste different sets of data. Here is a good exampl, let's say I need to be able to past my email somewhere but on another program or webpage I need to paste my home address.

• Computer not displaying anything

  - by Justen

  The computer in question worked last week. It's brand new, never been connected to the internet, up-to-date parts, etc. Last week, I installed some 3D software on it, then shut it down and waited for the license files that arrived this week. I've done this to 4 other PCs with the same hardware and software. I've tried: Hooking it up to 3 different monitors using different video cables 2 other graphics cards and a handful of other things like switching which port it's plugged into before and after a restart. I have the driver disc, and a windows reinstallation disc, but they won't do me any good because no display at all for any interval of time. All the fans are moving: psu, gfx, cpu etc, so I don't believe it's a power issue. Here are the specs I know of: 4GB RAM 8800 GTX 700w PSU Intel dual core (not sure of model) Anyways, I'm open to ideas.

• is a mini PCIe SSD worth it?

  - by Narcolapser

  Question: Is getting a mini-PCIe worth investing in? Info: I have a an Acer Aspire 1 n270. It has this mini PCIe slot that is just sitting there empty. I would like to change this, and I would like to speed up my boot time. So I've been considering getting a mini-PCIe SSD. They are about the same price as faster same size drives of the 2.5" variation. The advantage of the mini-PCIe card is that I can have my HDD still. So I have good boot time, but still have the storage of my HDD. What I want to know is: will this allow me to spin down the HDD more often allowing me to save power? Will the OS (Ubuntu 10.04 LTS) see them as separate drives? Is there anything that the mini-PCIe slot could be better used for? Thanks. ~n

• The best software for users internet usage

  - by nikospkrk

  Hi, We are a small business using a Vigor 2820 as the internet router, and we'd like to install a software that could report any internet usage from our users. I already tried the "official" software made by Draytek called "SmartMonitor", but is reliability is a real issue as it doesn't seem to keep capturing packets after working 3 to 6hours (randomly), whereas Wireshark keeps capturing packets after that amount of time. As I'm really fed up with this tool, I'm looking for other solutions but I still want the same features: users statistics, websites ranking, users traffic, ... I already enabled the port mirroring feature, so it would be perfect if you could suggest me a port mirroring-based software (ideally freeware). I thought I had found the good one with Etherscout, but it just doesn't launch. I am even open to a tool that would "just" make some reports based on Wireshark captured files (*.pcap). Thank you for any of your suggestion, Nicolas.

• How can I be sure that the motherboard is dead and it's not another issue?

  - by Peter

  So I have and old computer with and Intel D101GGC motherboard and a pentium 4 cpu and award bios, with a long repeating beep and not passing POST. I tried: RAM checking, they are good and working on other computers Replacing the PSU with a tested one, and still having the same issue I assumed that the CPU is dead and tested 2 others they are both Celeron D processors I also tested the CPU of this computer on another one and it's working fine I also tried it without RAM and still have the same long beep I did all this after disconnecting all the other hardware like HDD and DVD drives. The only time I didn't get any beeps is after removing the CPU I don't know if the processor is needed for the beeps to work. So My questions are: is it normal to not get any beeps if we don't have a CPU installed ? am I missing something or is the motherboard dead ? and thanks in advance.

• Beginners advice on Small business network disk(s)

  - by Rob

  We are having 10 PCs used by various user and presently use one network disk (a LaCie NAS) for all our data. Everything is Windows Vista and our collective IT hardware knowledge is minimal. This worked well generally. However, recently the disk freqently loses connection from the network (2-3 times per week) and the only way back seems to be the "turn it off and back on" trick. This obviously cant be any good for the disk. I understand that there are various more sophisticated ways of storing data and was wondering what people would recommend. One of the worries is obviously disk failure (either in part or as a whole) and the lack of continued availability due to network issues. I would guess that a disk which replicates data wouldnt work as a sole solution due to the network connection, but dont know what hardware (and/or software) would/could work in our case. In terms of size, we are looking at very small amounts, ie. less than 500 GB in total.

• Lenova B460e laptop Unknown filesystem

  - by Dinesh

  I got Lenova B460e laptop yesterday (by TN Govt). It has WINDOWS 7 Proff….. Setup it up the way I liked it... all software drivers and all. I wanted extra drives, so I entered the WINDOWS diskadmin and changed my partition setup, by splitting and I did the partition setup in the installing proces, so I splitted my harddisk into 4 parts. So far so good. When I rebooted, I entered GRUB RESCUE MODE. In this mode I know the only command “ls”. Which gives like (hd0) (hd0,msdos5) (hd0,msdos4) (hd0,msdos2) (hd0,msdos1). In this Lap I do not have CD drive also, otherwise I could have done Format the OS and installed new OS using WINDOWS 7 CD. Now I don’t know what I’m supposed to do. Anyone an idea how to fix this?
