• Quad Core host with hyper-threading, how many processors to configure in VirtualBox?

  - by Anthony

  I have a quad-core i7 processor with hyperthreading (8 logical cores), when I configured a virtual machine to use 8 processors, VirtualBox gave me a warning saying that I only have four cores (which is true) and that this may cause a performance issue. But hyper-threading is a hardware feature, so the OS sees 8 cores and it sends instructions to all 8. What if setting it to 4 caused the VM to use 2 cores (4 threads) instead of 4 simultaneous threads (on all 4 cores)? Does the warning I got take into account that my machine has hyper-threading?

• Make SoX not show output

  - by Ram Rachum

  I'm recording with SoX, and I want to make it not show output at all. When recording, it shows this output: Input File : 'default' (waveaudio) Channels : 2 Sample Rate : 48000 Precision : 16-bit Sample Encoding: 16-bit Signed Integer PCM In:0.00% 00:00:00.68 [00:00:00.00] Out:28.7k [ | ] Clip:0 I tried setting verbosity to 0, but it has no effect. (I'm guessing it's meant for messages other than this.) I don't just want to hide the output, which I could do easily; I want SoX to not generate it in the first place, for performance on a weak computer.

• SQL 2008 R2 3rd Party Peer-to-Peer Replication, Global Site Distribution

  - by gombala

  We are looking at hosting 3 globally distributed SQL Server installations at different data centers. The intent is that Site A will serve web traffic and data for a specific region, same with Site B and C. In the case that Site A data center goes down, looses connectivity, etc. the users of Site A users will fail over to Site B or C (depending which is up). Also, if a user from Site A travels to Site C they should be able to access their data as it was on Site A. My questions is what SQL replication technology (SQL Replication or 3rd party) can support this scenario? We are using SQL 2008 R2 Enterprise at each site, each site runs on top of VMWare with a Netapp filer. Would something like distributed caching help in this scenario as well? We have looked at and tested Peer-to-Peer replication but have encountered issues with conflicts during our testing. I imagine there are other global data centers that have encountered and solved this issue.

• Partitioning Software for Windows 7

  - by nunos

  I used to use Patition Magic Pro from Norton to do disk partitioning. Now that I have Windows 7, I have been warned, by the OS itself and later confirmed on the internet, that Partition Magic Pro has compatibility issues with Windows 7. So, I am asking you which software partitioning software do you recommend. It would be great if it was freeware but I know it is hard to find a good parititioning app that's free, so, if you know a good one that's paid, there's no problem and please mention it in your reply. Thanks in advance. P.S. I am aware of "create and format disk partitions feature" of Windows 7, but that's not enough for me. I am using Windows 7 Professional 64 bits.

• Making python run on my webserver

  - by richzilla

  Hi all, im getting a bit stuck regarding options for running python scripts on my server. From the research ive done so far, i can see i need to modify apache slightly to run python scripts, by using either mod_wsgi or mod_python. Two issues i have: mod_python doesnt appear to be maintained anymore (last release, 2007) mod_wsgi appears to require modification of my httpd.conf file on a per application basis. What im wanting to know, is there a way of getting python scripts to run in the same way as php, i.e. just by going to index.py etc... or is it more involved than that? At present im just trying to set it up on my xampp install. Any help would be appreciated.

• Advice for migrating email server

  - by Chris Adams

  Hi there, I'm planning to migrate a Zimbra server with about 200gb of data from a server hosted in an office into a datacentre, to increase uptime (we've had a couple of outages when our network here started flaking out, and we have people in other countries relying on this server too). However, I'm not sure how best to migrate the data into the data centre without rendering the connection unusable during office hours, because there's far too much to send in over night over the two meg upstream connection we have here. I'm familiar with using tools like nice to stop a long running process degrading machine performance - is there a simple way to throttle a connection between office hours, so the long running transfer doesn't block the pipe, but then opens up outside of office hours to make the most of the bandwidth? I'm aware the alternative here is to simply mail a hard drive to the data centre, but I'd like to avoid doing that if I could. We're using Centos Linux for our servers, in the office and the datacentre, so extra points for an open source linux answer.

• Windows 7 - problems launching default application

  - by Chris W

  Just built up a new W7 PC. I've noticed some strange issues with launching default applications. I've got Visual Studio & SQL Server Management Studio set run as administrator when launched. If i double click a .sql file SSMS opens ok but the file itself does not get loaded. If I do the same with a .sln then I get nothing at all from Visual Studio. For the latter I presume the UAC prompt is hidden somewhere waiting for me to say it's ok to launch the app but i've no idea what's happening with SSMS. Is this a W7 bug or are there some settings somewhere that I can tweak to improve this behaviour?

• Test site speed

  - by Elad Lachmi

  I am test driving an Akmai CDN architecture and before committing to buy, I would like to gauge the real performance gain from the acceleration feature. What would be the best MO for doing speed tests from different locations around the world? I would like to test the page load speed and not just the server response time. I would like to test speed from as many edge locations as possible. I do not mind a paid service as well, if it is optimal. Thank you!

• WBAdmin SystemState Problems

  - by TheD

  I recently installed DHCP on my 2008R2 Server and now Backup Exec and WBAdmin/WSB is having System State issues. Essentially, after some research, I came across a handy tool called VSHADOW which has allowed me to output all the files (and their respective directories) to a text file. And hooray, I think I found the problem: * WRITER "Dhcp Jet Writer" - WriterId = {be9ac81e-3619-421f-920f-4c6fea9e93ad} - InstanceId = {0ed0a8f4-19b0-414d-a3a8-d51d6f4ac8e0} - Supports restore events = TRUE - Writer restore conditions = VSS_WRE_IF_REPLACE_FAILS - Restore method = VSS_RME_RESTORE_AT_REBOOT - Requires reboot after restore = TRUE - Excluded files: - Component "Dhcp Jet Writer:\C:_Windows_system32_dhcp\dhcp" - Name: 'dhcp' - Logical Path: 'C:_Windows_system32_dhcp' - Full Path: '\C:_Windows_system32_dhcp\dhcp' The logical path and Full Path for DHCP is completely wrong. However I can't find where I would change this path, I assume in the registry but I've had no luck finding the key !

• What settings to use for fastest reloading of a MySQL backup?

  - by Alex R

  I have a MySQL database which dumps to a 3.5 GB backup (mysqldump) in about 10 minutes. But reloading this backup on a standby / test server takes upwards of 12 hours. What are some settings that would maximize reloading performance? The most promising appear to be innodb_buffer_pool_size, innodb_additional_mem_pool_size, and innodb_log_buffer_size... but I'm reaching the limits of my trial-and-error approach. Which of these settings "should" be the most important? Through trial-and-error I was not able to get more than 70% CPU utilization and 63% memory utilization. I'd like both at 100% during a reload. All tables are InnoDB.

• XP Install Driver Notification for AirCard

  - by Brian

  Hello, A co-worker of mine is using an air-card; it prompted him to install software in the notification tray; he clicked on the wrong thing and the icon went away without him installing that software. How can I get that icon back? He can't install the software then... I know that you can download the software from the site, but we did that and were having issues from that too, was hoping to be able to install the sofware on the air card... Restarting and trying again doesn't pop up the notification too. Thanks.

What else can I try ?

• Changing bounds of excel file embedded in powerpoint

  - by Brett

  When I embed an excel files into powerpoint, I'm having two issues. On some of the spreadsheets, empty columns are displayed on the right hand side of the powerpoint slide On other spreadsheets that are too large to fit, I can't adjust the bounds of what I'd like to be displayed on the slide. So, I couldn't choose a larger area to display of the excel spreadsheet and just size it down. It arbitrarily chooses where to cut off the excel spreadsheet on the slide. Is there any way to adjust which part of the excel file is embedded?

• CPU?: Not responding

  - by James

  I'm attempting to build a system for co-location. I've been running into issues while trying to install CentOS 6.3 System Specs: Motherboard: ASUS m5a99x Process: AMD FX-8120 (8-core Bulldozer) Memory: 2x 4gb G-Skill 2133 running at 1600 I keeps giving me an error message: CPU1: Not Responding. CPU2: Not Responding. CPU3: Not Responding. CPU4: Not Responding. CPU5: Not Responding. CPU6: Not Responding. Then it instantly restarts. I have tried installing it from USB, Multiple DVDs, Multiple Distros. I have also in the bios attempted to disable cores. I was able to disable 2/3 4/5 6/7. I have also ensured that there is zero overclocking. The system works fine in a windows environment. I'm out of ideas.

• perfmon reporting higher IOPs than possible?

  - by BlueToast

  We created a monitoring report for IOPs on performance counters using Disk reads/sec and Disk writes/sec on four servers (physical boxes, no virtualization) that have 4x 15k 146GB SAS drives in RAID10 per server, set to check and record data every 1 second, and logged for 24 hours before stopping reports. These are the results we got: Server1 Maximum disk reads/sec: 4249.437 Maximum disk writes/sec: 4178.946 Server2 Maximum disk reads/sec: 2550.140 Maximum disk writes/sec: 5177.821 Server3 Maximum disk reads/sec: 1903.300 Maximum disk writes/sec: 5299.036 Server4 Maximum disk reads/sec: 8453.572 Maximum disk writes/sec: 11584.653 The average disk reads and writes per second were generally low. I.e. for one particular server it was like average 33 writes/sec, but when monitoring in real-time it would often spike up to several hundreds and also sometimes into the thousands. Could someone explain to me why these numbers are significantly higher than theoretical calculations assuming each drive can do 180 IOPs? Additional details (RAID card): HP Smart Array P410i, Total cache size of 1GB, Write cache is disabled, Array accelerator cache ratio is 25% read and 75% write

• Efficient PuTTy workflow / configuration

  - by Adrian Ratnapala

  PuTTy is a fine SSH client, but how do you get a workflow managed as slickly as OpenSSH on Unix? My issues with PuTTy's management are: PuTTy tools are not in my PATH (easily fixable) PuTTy seems to have no equivalent of ~/.ssh, so I end have to manually choose locations for my keypairs, and then manually tell all the tools where to find them every time The private key's read permissions seem lax (I might be wrong about this, I a klutz on Windows). Pageant doesn't run by default (easily fixable?) Other programs don't reliably find pageant I suspect all of these problems can be fixed if I just get set my system up properly, and/or organise a nice workflow that fits into PuTTy's way of doing things. So can anyone share some success stories about managing PuTTy?

• Parity Initialization after putting in two new disks

  - by lbanz

  All my firmware is up to date on the server and the controllers. Storage crashed over the weekend. I rebooted it and it detected that I put in two new disks last week (I did check that both disk completed the rebuilding process last week). After it booted into the OS I see that it gave me an information message. After 18 hours it is at 54% so it is looking healthy. But I need to replace 5 more disk in the msa. Should I wait for this message to finish before replacing more disks? 785 Background parity initialization is currently queued or in progress on Logical Drive 1 (15.0 TB, RAID 5). If background parity initialization is queued, it will start when I/O is performed on the drive. When background parity initialization completes, the performance of the logical drive will improve.

• How do I install Netatalk in Ubuntu 9.10 (tutorial)?

  - by Phobis

  I have never installed Netatalk before. I have to help someone get this up and running on a Ubuntu 9.10 server and I don't know if there is any special configuration or install steps I need to follow in Ubuntu 9.10 to get it up and running. I know in older versions of Ubuntu, specifically, special OS changes and configuration needs to be done in order to get it to work properly. Do I need to work around any of those issues in 9.10? I am doing this remotely through ssh, so I prefer instruction via command-line. Thanks!

• Can't delete keyboard shortcut set for a .ink file

  - by Sirhaian

  So, I installed the Chrome App Launcher on my PC (now on Win8.1) a few weeks ago, and, as I use it very often, I wanted to assign a keyboard shortcut for it. So, I right-clicked the icon on my desktop, and I assigned Ctrl+Alt+<. The problem is... I moved the shortcut to my taskbar, and suddenly noticed that when I wanted to write the "\" (on a Belgian keyboard), it launched the Chrome App Launcher, which is very annoying. I wanted to change it back, but I can't... I deleted the taskbar shortcut, but the keyboard shortcut still launches the App Launcher. I also tried creating a new shortcut with the same association, hoping that it would crush the existing one, but it didn't work. I searched on Google for similar issues, and I couldn't find any... x~x So... How can I delete this shortcut association..?

• Connecting to Google SMTP with Konica Minolta Printers

  - by VictorKilo

  I have spent the better portion of two days trying to get a number of Bizhub MFCs to connect to Google's SMTP service. Our company recently switched from an exchange server, which handled SMTP requests to Gmail. We have 20 branches each with different MFCs. I was able to get the Cannons connected, but the Konicas are giving me major problems. The three models that are giving me issues are the C203, C250 and the C280. I have used the following: smtp.gmail.com port 465 Gmail Username/Pass aspmx.l.google.com port 25 no authentication aspmx.l.google.com port 25 Gmail Username/Pass None of these methods are working despite the fact that all of those have worked on different makes/models. Any help would be greatly appreciated, I'm at my whit's end.

• suddenly can't connect to windows 7 pc from xbmc

  - by Damon

  I have xbmc installed on a softmodded classic xbox and all of a sudden I cannot connect to the shared folders on my windows 7 PC. Well, it can connect but it wants a username and password, but none exist on my computer. It's been several weeks since I last used it, but it was working fine then! and no particular changes I can think of aside from I guess a few windows updates. I've seen reference online to windows live essentials causing issues with file sharing, but I don't even have that installed. And I made sure to tick 'turn off password protected sharing' in my advanced network setup. I had the guest account turned off and working fine before, and tried turning it on but no luck. I can access my shared folders fine from other Computers and a ps3. I've read a couple threads of similar situations on various folders and none of their solutions have worked.

• MongoDB on FreeBSD

  - by Hartator

  We are currently using MongoDB 2.0.0 on MacOS but our servers are running FreeBSD. The most recent port of MongoDB is the 1.8.3 version. I have tried to compile the 2.0.0 by hand but I came across errors that I didn't manage to fix. I came across on the Internet a few old resources which are saying that MongoDB does not run well on FreeBSD mainly for performance issue (memory mapped files). Is that true ? Does it mean we have to switch our server to another OS ? Thanks for your opinions!
