  • SQL Server 2000 tables

    - by user40766
    We currently have an SQL Server 2000 database with one table containing data for multiple users. The data is keyed by memberid which is an integer field. The table has a clustered index on memberid. The table is now about 200 million rows. Indexing and maintenance are becoming issues. We are debating splitting the table into one table per user model. This would imply that we would end up with a very large number of tables potentially upto the 2,147,483,647, considering just positive values. My questions: Does anyone have any experience with a SQL Server (2000/2005) installation with millions of tables? What are the implications of this architecture with regards to maintenance and access using Query Analyzer, Enterprise Manager etc. What are the implications to having such a large number of indexes in a database instance. All comments are appreciated. Thanks

  • Large svn external

    - by MPelletier
    I have a project which uses a large library residing in its own repository. Using: Tortoise-SVN, the server is running an enterprise edition of VisualSVN The project itself has the "standard" structure: trunk tags branches In each branch, tag, and trunk is the library, set as an external (svn:external property). If I get the entire tree, I get the library several times, which is just getting too ridiculously repetitive. Is there a recommended structure for this? Or perhaps a way not to get all externals (because other externals are much smaller, easier to manipulate)?

  • Good/Better config for MySQL on an EC2 Large Instance

    - by Tim Reynolds
    I have an EC2 Large instance dedicated to MySQL. It will be serving a Joomla/Magento combo so it has a blend of InnoDB and MyISAM tables. I have only worked with MyISAM in the past and am therefore unfamiliar with the settings InnoDB uses. Experiments so far have been less than fruitful, as I keep causing the InnoDB engine to be disabled. My instance is running Ubuntu 10.04 64 bit server edition and has ~7.5G of ram. MySQL is currently using ~0.6% of that, with somewhat poor performance. I would like to configure it to use as much of the system RAM as is reasonable. Testing some settings I learned that the InnoDB logs can't collectively be larger than 4G. Would anyone be able to provide some base InnoDB and MyISAM settings to get my started. Thank you Tim

  • Booting large ISO through PXE

    - by Devator
    I currently have a FOG server (which works perfectly fine) and I'm trying to boot Windows 7 through it (with memdisk). But, since the ISO is rather large (more than 6 GB) it will try to put the ISO into memory and then boot however it crashes with the error message not enough memory to load specified image. The systems here don't have 6 GB of RAM so I need another way to boot it. I am aware of WDS and SCCM, however I want todo this with FOG. Is there any way to boot the ISO and install Windows through FOG?

  • Large Users Profile - Windows 7 - Machine running slowly

    - by Richard
    I have the MD of a client of ours who has a Windows 7 Profile that is currently 14GB thanks to Videos/Music and Documents. The first thing we did was to switch from roaming to local. What I need to know is now the profile is local am I wasting my time by reducing it any further? Does it really make a difference to performance having a large local user profile? Only the 4GB outlook ost that talks to the network frequently. Thanks in advance.... Richard

  • Classic ASP on large memory server

    - by Steve Evans
    I have a client with a large ASP app that apparently is fairly memory intensive. I’m helping them migrate to new hardware they have running Win2k8 R2. They have 4 physical servers with 32gb of RAM each. I’m making the assumption that ASP apps run as a x32 process. So I see that we have two options: On the application pool enable web gardens. Use the physical servers as VM hosts and split the box into say 4 web servers each. Any thoughts on which path will provide us better performance? I’m just not really sure how ASP will handle a machine with lots of memory, and I’m worried it won’t really be able to address the memory well. (you can ignore all the obvious stuff like increased maintenance of 16 web servers vs 4, or the flexibility virtualization gets us over physical servers, etc)

  • Apache, Django with mod_wsgi, and large request buffering

    - by Mukul
    In my setup of Apache 2.2 MPM worker and Django 1.3 with mod_wsgi 2.8, I need to support large POST request payloads. The problem is that when there are many such simultaneous requests, Apache uses up all the memory in the system and then crashes. It seems that Apache is buffering the requests completely in memory before executing the WSGI handler and passing it the request. Is there any way to control request buffering in Apache? The log shows the following error whenever the crash happens: [Wed Jun 29 18:35:27 2011] [error] cgid daemon process died, restarting Here's my virtual host's configuration: <VirtualHost *:8080> ServerName example.com ErrorLog /var/log/apache2/error.log WSGIScriptAlias / <path to django.wsgi> WSGIPassAuthorization on WSGIDaemonProcess example.com WSGIProcessGroup example.com XSendFileAllowAbove on XSendFile on </VirtualHost>

  • secure synchronization of large amount of data

    - by goncalopp
    I need to automatically mirror a large amount (terabytes) of files in two unix machines over a slow link (1 Mbps). This needs to be done frequently, but the data doesn't change too much (delta transmission doesn't saturate the link). The usual solution would be rsync, but there's an additional requirement: it's undesirable, from a security standpoint, that either the source or destination machines have (keyless) ssh keys to each other, or any kind of filesystem access. All communication between the two machines should thus be initialized (and mediated) through a third machine. I've asked a separate question about rsync in particular here. Are there other obvious solutions I'm missing?

  • Connection drops while transferring large files to one server on a network

    - by Charlotte
    My company has two sites, each with their own LAN, using site to site VPN tunnel to connect the two sites. When transferring files (especially larger files) from site1 to site2 server1, the file transfer fails. I don't think this can be a VPN issue because transferring the same files to site2 server2 which is on the same network as server1 works fine. Pings to server1 and server2 at site2 from site1 are about the same, mostly 19/20ms with the odd one up to 50ms. As server1 is DB server with a high load I thought the NIC maybe overloaded, but a transfer from site2 server1 to site2 server2 works fine, and that uses the same NIC on server1 as transfers from site1 to site2 server1. The servers are both Windows Server 2003 VMs with VMXNET 3 NICs.

  • How To Speed Up Adding Column To Large Table In Sql Server

    - by Chris
    I want to add a column to a Sql Server table with about 10M rows. I think this query would eventually finish adding the column I want: alter table T add mycol bit not null default 0 but it's been going for several hours already. Is there any shortcut to get a "not null default 0" column inserted into a large table? Or is this inherently really slow? This is Sql Server 2000. Later on I have to do something similar on Sql Server 2008.

  • design a large scale network for an organization

    - by Essam
    i want to design a large scale network for an organization with HQ and two branches. i want to use a class A subnet. if i am using the network address 30.0.0.0 for the whole organization how can it be different from another organization company or whatever which is using the same address in another country? now i have the three locations for this organization,so i need 5 subnets [one for the HQ,two for branch A and branch B , one for connecting A to HQ and one for connecting branch B with HQ since i will use central DHCP server at the HQ,is that (number of subnetting) right? is it advisable to use class A or class B for this organization it term of address that will be wasted (let's say it is a university with two branches in two different states)?!

  • Downloading a large site with wget

    - by Evan Gill
    Hi, I'm trying to mirror a very large site but wget never seems to finish properly. I am using the command: wget -r -l inf -nc -w 0.5 {the-site} I have downloaded a good portion of the site, but not the whole thing. The content does not change fast enough to bother using time-stamping. After running overnight, this message appears: File `{filename}.html' already there; not retrieving. File `{filename}.html' already there; not retrieving. File `{filename}.html' already there; not retrieving. File `{filename}.html' already there; not retrieving. Killed does anyone know what is happening and how I can fix it?

  • How do you manage large web farms?

    - by Andrew Katz
    I have a quickly growing web farm running IIS 7 (30+ servers). All servers are identical copies of each other and all servers are physical. We update the software about once a month, and in the current process, we follow the following steps: Disable server from pool on F5 load balancer. Disable HTTP Keep-alives in IIS so connections drop quickly. Change default directory of website to new folder containing new binaries. Test server Enable HTTP Keep-alives. Enable server in F5 pool. Move to server 2 Microsoft used to have Application Center which was abandoned a while ago. They have made a second attempt with the Web Farm Framework, but this adds as much QA time testing the release package as it saves in the deployment. Has anyone seen a commercial off the shelf application that is tailored for managing and deploying to large web farms? Thanks!

  • Photoshop / Illustrator Fill text box with large string.

    - by Xetius
    I have a massive string (lots of Fibonacci numbers concatenated together). I don't know how much of this text I need to fill an A4 page. What I was hoping for was to paste a large block into a text box and have it display as much as possible, wrapping the text at the end of a line, but it is not doing that. It is just displaying a blank box (With the text overflowing into an awaiting textbox or something. I have tried pasting smaller amounts of text into the text box, and it appears that it will get about half way and then go into 'blank' mode. All I need is a simple way of creating a background of numbers which I don't have to type in. Any ideas?

  • Backups of Exchange 2007 SP3 using VSS are abnormally large

    - by Stew
    I have recently implemented Veeam backup and recovery 6.0, and have noted when backing up my exchange server via incremental updates, it is transferring way more data than expected. Backup is incremental, and setup to use VSS. VSS is stable and healthy, according to vssadmin. Exchange 2007 SP3 running on Windows Server 2008 R2, just last weekend I installed the latest Rollup for Exchange. I thought the nightly incrementals were large, but perhaps my users really are sending that much mail so I tested taking one incremental backup, waiting 10 minutes and taking a second. The second incremental backup transfered 5.8GB of data. We as an organization are absolutely NOT putting 5.8GB of data on the mail server every 10 minutes. Are there any other veeam users who have seen something similar? Is my test faulted? Are there other considerations for VSS?

  • md5sum of large files gives different results sometimes

    - by Emanuele
    I have an AMD quad core, 8 gb RAM, 1 SSD EXT2 (2 months old), 2 HDD EXT4, approximately 1 year old. I'm using Ubuntu 10.04 x86-64 and when I compute the md5sum of large files (9 GB) sometimes I get different values than the one stored on a reference file. Upon restarting and switching off the PC then I get the expected results no matter how many times I repeat it. But this is random. I've turn on ECC (the fastest possible settings) and the issue seems to be rarer, but I've run memtest86+ for 6+ hours without a glitch (and with ECC off!). Any idea? Should I update the BIOS of my motherboard (Asus EVO-something...don't remember it now)? I've tried all the rest apart this, but genuinely don't know what to do anymore... Any suggestion is appreciated!

  • A raw dump from a corrupted large file

    - by Masoud M.
    I have a large .rar file inside partion D (Windows7/NTFS). It's corrupted due to bad sector (I think) and when I copy it to another place (External-HDD) the system freezes after 88% of progress. I even tried to copy it with my Ubuntu and same problem occurred. Also I tried chkdsk and it dosen't fix it. I think my last chance is dump that file with a tool which ignores bad sectors and create a raw copy of it. Then I will repair the file with rar tools. But I can not found a tool to raw dump a specific file. (In linux there is dd tool but it dumps all partition and I can not use it) So, Is somebody know a tool to do a raw dump from a file?

  • How to copy/paste LARGE amounts of text in Windows

    - by Johnson
    I am not sure if this is more suited for Superuser or Stackoverflow, but here goes... A little bit of background: I'm learning SQL and was trying to make a very large table which I could use for optimization tests. Something generic with random values. I created a little Java program to do just that, and was able to put out a text file with 100,000 lines, each line being an SQL INSERT statement for a new random record. However, with anything much bigger than 100,000 lines, I had problems either opening/using the text file in any text editor, or copying/pasting the text to the windows clipboard and then into SQL Developer so I could execute it as a script. I'm probably overlooking something really obvious, or doing something really stupid. There has got to be a better way to do this, but I couldn't find anything through Google or Stackoverflow or Superuser. Thanks!

  • Need to transfer large video from Camera!-app to computer

    - by Henrik Söderlund
    I have a jailbroken iPhone 4S and am trying to transfer a 25minute long HD-video that I have recorded through SmugMug's Camera-Awesome (Camera!) app. Once recorded in the app, it stays within that app's interface until you choose to save it via the app onto the camera roll. When trying this option, the app just stalls, even when leaving it for an hour plus. I assume the video is too large to copy. I am trying the iExplorer app on my MacBookAir. I can find the Documents folder inside the Camera!-folder. But as soon as I access it to view the contents, it simply stalls the app completely. Probably after trying to read the enormous video. Is there a clever way to transfer this file onto the computer? I can use iFile on the iPhone to transfer through wifi, but I don't know the Camera! app's Documents folder location on the file system.

  • Clean out a large MediaWiki text table

    - by Bart van Heukelom
    I just discovered that an old MediaWiki of mine was infested with spam, and the database table named "text" (which contains the page content) is 3GB large. I've deleted all the spam pages manually, but: The table is still the same size. I wonder how it got to 3GB anyway. There wasn't that much spam (about a hundred medium-sized pages) How can I get rid of this mess? If you want to inspect the wiki, it's over here. The database is MySQL 5.0.75.

  • Manage Large E-Book Archive

    - by Cnkt
    I have a very large e-book archive (approx. 1TB) including various file formats eg. PDF, DJVU, MOBI and EPUB. I put them in different folders by subject eg. Engineering, Programming etc. But after many years, things are going crazy. The programming folder itself is 220GB and file names are cryptic. Some filenames are well defined like: 236659889_Final_Report_of_2012_Climate_Change_Conference.pdf but some filenames are just ISBN numbers or just download.pdf. I need an application for organizing and searching my e-books. I already tried Calibre, Mendeley and Debenu. But all these apps try to import files first and I dont have any spare 1+ TB for the apps import folder. Is there any good Windows application for just indexing filenames and contents of ebooks without importing them?

  • Copying large Windows directory structure to new server with permissions intact

    - by Chris
    I'm soon going to be doing a large migration of an old-school web server that serves mostly ASP pages (currently on a Windows 2003 server) to a newer, virtualized Windows 2008 server. This new server is going to be in a different domain, as well. So I'm copying the root web folder, and all its subfolders and files, to this new server. I'd like to keep permissions intact. It's also pretty massive - I'd like to be able to compress it before transferring to the new server with permissions intact. Any way to do that? And will the new server being in a different AD domain screw with my plans?
