  • Oracle data warehouse design - fact table acting as a dimension?

    - by Elizabeth
    THANKS: Both answers here are very helpful, but I could only pick one. I really appreciate the advice! our datawarehouse will be used more for workflow reports than traditional analytical reports. Our users care about "current picture" far more than history. (though history matters, too.) We are a government entity that does not have costs or related calculations. Mostly just counts of people within given locations and with related history. We are using Oracle, and I have found distinct advantage in using the star join whenever possible and would like to rearchitect everything to as closely resemble the star schema as is reasonable for our business uses. Speed in this DW is vital, and a number of tests have already proven the star schema approach to me. Our "person" table is key - it contains over 4 million records and will be the most frequently used source in queries. It can be seen at the center of a star with multiple dimensions (like age, gender, affiliation, location, etc.). It is a very LONG table, particularly when I join it to the address and contact information. However, it is more like a dimension table when we start looking at history. For example, there are two different history tables that have a person key pointing to the person table. One has over 20 million records and the other has almost 50 million and grows daily. Is this table a fact table or a dimension table? Can one work as both? If so, is that going to be a big performance problem? Is it common to query more off of a dimension than a fact? What happens if a DIFFERENT fact table that uses the person table as a dimension is actually only 60,000 records (much smaller.). I think my problem is that our data and use of it does not fit with the commonly use examples of star schemas. CLARIFICATION: Some good thoughts have been added below, but perhaps I left too much out to really explain well. Here's some more info: We handle a voter database. We don't have any measures except voter counts by various groups: voter counts by party, by age, by location; voter counts by ballot type and election, by ballot status and election, etc. We do have a "voting history" log as well as an activity audit log (change of address, party, etc.). We have information on which voters are election workers and all that related information. I figure I'll get to the peripheral stuff later. For now I'm focusing on our two major "business processes": voter registration(which IS a voter.) and election turnout. In the first, voter is a fact. In the second, voter is a dimension, along with party, election, and type of ballot. (and in case anyone is worried - no we don't know HOW people vote. Just that they do. LOL ) I hope that clarifies things a bit.

  • How can I stop sysprep from interacting with boot on windows 7

    - by Grofit
    I have recently had a laptop sent back to supplier for fixing a mainboard fault. I got it back today and every time it boots up I am faced with: "Setup is preparing windows for first time use" Then once it gets to the desktop I get the sysprep dialog come up asking if I want OOBC or Audit actions. I can close it, but it just keeps coming back, and I cannot find any startup or boot actions, even downloaded autoruns, and that cannot find anything to do with it. Ideally I do not want to format/fdisk as I have just spent hours installing everything on the laptop and I have my primary C:/ which has all windows and at worst case I can get rid of that, but I have a secondary partition D:/ which has alot of stuff I cant lose as its work related and important. Also to make matters more difficult I do not have a windows 7 disk, it was just pre-installed and they dont provide a disk. Any help would be great!

  • Hide non VHD partitions

    - by James
    Hey! I have two partition on my HDD: C and D. On D: I have a vhd image (with windows 7 ultimate) that I use to boot from. When I'm running the OS from VHD I can still access my physical parititons. Is it possible to dismount them, in order to see just the virtual disks in the VHD OS? I tried with the physical C and it says that I cannot dismount a boot paritition and I think D cannot be dismounted because the VHD is on it.

  • Loadbalance UDP traffic with session affinity and way to take servers in & out of rotation

    - by William
    What is the best way to go about load balancing UDP traffic among a whole bunch of servers, while keeping session affinity based on the users' IP? I need to also be able to take servers in and out of rotation for new clients, so when they join for the first time, they get put on a server in a list of available servers, and clients already connected would stay connected to their specific server. I have written the software to maintain a list, but I can't seem to find anything that would perform this functionality. If you need the context, this is to facilitate game tournaments for Minecraft: Pocket Edition, which is done with UDP traffic, I cannot change the protocol. And, because tournaments open and close, I need to be able to place players on their proper servers. Performance is also a priority, I have a program to do this but it is very bloated and slow. Thanks for any help! William

  • Cannot find my hard disk while installing linux-“No root file system defined” error

    - by Syam Kumar S
    I am trying install Linux on my computer (tried Ubuntu 10.4 and Linux Mint 9). I started the installation wizard and on the hard disk selection page the hard disk is not displayed. I have a 500GB disk with 5 partitions and windows 7 ultimate in one partition. If I click the forward button, it shows an error- "No root file system defined". I have tried to install by booting from CD and pendrive but both shows the same error. When I load Linux as live CD it doesn't show the hard disk. My hard disk works fine in windows 7. System config: intel i3 2100, 500GB hdd, 2GB ram

  • Entering new user data into AD LDS

    - by Robert Koritnik
    I need some help configuring AD LDS (Active Directory Lightweight Directory Services). I'm not an administrator, have never configured domains and I don't have a clue how to add new users to existing domains. The thing is I need to develop an app on top of Sharepoint 2010 that must be connected to AD. I've chosen AD LDS because I can install it on Windows 7 and it acts as an active directory even though there's no domain controller present in the network. What I've done so far: I've installed AD LDS I've added a new instance with appication directory partition name DN=Air,DC=Watanabe,DC=pri I can connect to it using ADSI Edit and see all kinds of strange But now I don't know what to do? When it opens I can see the window below, but where's next? Can anybody give me some guidelines, how can I add domain users, so I can use them in my app AD required app?

  • Cannot format SD memory card

    - by cool
    Hello everyone I have a SD memory card which is of local manufacturer it allows to read & copy from it but not write as it is now write-protected so i want to format that card but could not. To format this card I have tried 1) DD command 2) mkfs -f vfat command 3) creating registry entry under storage device policy in window with write value 0 4) disk part command in window to clear attributes in which it show all attributes are clear ie no write protection 5) I format card in windows through control panel - administrative tools- computer management - disk management, then it show as formatted but when I tried to create new partition it give CYCLIC REDUNDANCY CHECK error 6) I downloaded a format utility from transcend site and formatted first it shows write protected again doing format it formats and tells to remove and reinsert after reinsertion it shows the previous data as it is

  • If I split my harddrive, will a system restore delete it?

    - by AoiHana
    I split my 1TB HD from C drive and called it A. I put some files there to back up. I have now come to a point where I need to run a system restore with the discs that came with my computer. If I do a system restore and wipe C drive clean, will I lose the part of the hard drive that I split or will it remain intact and my files uncorrupted? This is a partition I created with windows myself, and dragged files over to it. Thanks!

  • What determines what resolutions a laptop is willing to output over VGA?

    - by Joshua McKinnon
    I'm responsible for several conference rooms and have setup 1080p projectors and I provide both HDMI and VGA connectivity. HDMI for DisplayPort and Mini-DisplayPort, and VGA as a fallback, universal option. Contrary to what I expected, people seem to have much more trouble with the HDMI than VGA, so VGA gets used a lot more than you'd think (even as most workstation laptops made in the last 3-4 years have DisplayPort or Mini-DisplayPort...). Also to my surprise, VGA outputs over 1080p on a 50ft cable run with very minimal degradation on certain laptops - other laptops just don't offer 1080p as a resolution choice and top out at 1600x1200 or something else. Specific example: a ThinkPad W530 will do 1080p, a W520 won't, over VGA. (both do 1080p over displayport/mini-DP) What determines what resolutions a laptop is willing to output over VGA? I'm thinking this will come down to either a video driver that says it supports only certain resolutions for output, or limitations of the RAMDAC (which wouldn't be in play, at least DAC wise, on a digital output, but WOULD on VGA, an analog output). The basic reason for the question is that I noticed, say, a ThinkPad W520 with 1080p built in display, will output 1080p fine over DisplayPort to a 1080p projector, but will cap out at 1600x1200 (practically the same pixel count, just a little shy) on VGA. Now, this wouldn't be surprising at all except SOME laptops have no issue outputting 1080p over VGA, even with lower native resolutions. Why do I care? Well if there's some way I could enable it... for situations where my users end up using VGA anyway, it's preferable for display mirroring if they can output their laptop's native resolution, which, you guessed it, is very often 1080p on 15" models. DISCLAIMER: This is primarily a curiosity, I'm not claiming 1080p over VGA is ideal by any means, but hey, if it works. I've seen HDMI start artifacting more over same-length, same gauge cabling (up to 50' run in certain rooms). If you think this is better suited to SuperUser, please move it, but this is framed from an IT standpoint of something that affects a real pool of users in a multiple conference room, 50+ deployed laptop scenario.

  • fedora 11 server won't boot from SATA disk, won't boot from CD, BIOS configuration problems

    - by Tom
    Hi all, Yesterday our fc11 file/print server didn't boot, and had stopped on the BIOS page with a configuration problem. (with a distinct lack of foresight) I reset the BIOS settings to default without recording the message and booted the server. The server ran until it was to be booted this morning, and it was failing to mount the root partition from the SATA disk. It also failed to boot from a known good diagnostics CD. After a few more tries, it now fails part way through the Phoenix - AwardBIOS screen where it is listing the SATA/IDE devices, and it is showing garbage for the identity of one of the disks, which should actually be "none" It looks like the motherboard has gone kaput. The motherboard is an EVGA NF790i, are there any diagnostic tools that I can use to determine this? (as I would prefer to not send the motherboard back, only to discover that it is the RAM or the CPU) ps I can't get it to boot from the memTest disk, so I can't run that diagnostic. Thanks!

  • XP Computer won't start (Missing/Corrupt 'System' file) - recently added new hard drive

    - by qwerty2
    Hi all, Pulling my hair out here. I recently replaced my D: 1TB drive (not a system drive) with a new 1.5TB drive. I loaded Windows XP, formatted the new drive and it was showing as working fine, alongside my C: windows system drive. I restart my machine and all of a sudden, Windows doesn't load and instead I get: "Windows could not start beause the following file is missing or corrupt" \WINDOWS\SYSTEM32\CONFIG\SYSTEM I don't have the original XP installation CD, although I do have another copy of XP, when I try and boot to it, I get the blue 'STOP' screen after it attempts to load the setup utlity for about a minute. Can someone please help? When I set up my new hard drive as a primary partition did this someone screw up my C: hard drive? Did it perhaps unmount it somehow? Any help would be fantastic. Thanks

  • Acer Aspire 3680 Wireless Signal Problem

    - by SHiNKiROU
    I am using Acer Aspire 3680. I recently reinstalled Windows Vista, and the wireless did not work by default. I installed the "Atheros Wireless LAN Driver" on this site: http://support.acer-euro.com/drivers/notebook/as_3680.html The result, the wireless APs are successfully scanned. However, when I tried to join a network, even with 5/5 signal, an error message showed up diagnosing signal too little. I restarted as Ubuntu, and wireless worked perfectly, with same computer position. Even more confusing, When I moved to the kitchen (2 meters close to the router), the wireless connected, when I move back to my room, wireless failed on Vista and worked on Ubuntu. It is clearly the driver problem. Acer laptops seems come with pre-installed drivers, but after re-installation, they are all gone. (I can't find the original Acer backup disc) Please do not answer "move closer to the AP" and something related to "interference", as wireless worked with Ubuntu's default driver.

  • Trouble recovering MySQL InnoDB database after server crash

  • How to repair the boot selection on grub?

    - by Zignd
    I had installed on my computer as a dual-boot: Debian Squeeze and Windows XP, so I decided to install Windows 8 just to test and then I would remove it and install in its place Debian Wheezy as dual-boot with Windows XP, that was already installed. During the Debian Wheezy installation, I deleted the Windows 8 partition to install Debian W. on its place. The problem is, that after the installation finished I rebooted the computer and on the grub menu was written: Debian Wheezy and Windows 8 (loader) - this Windows 8 (loader) is a boot manager as grub, and after the Win8 installation I was capable of choose between Win8 and WinXP. And when I select Windows 8 (loader) it says the Windows 8 is corrupted and is not possible to boot Windows XP. So, after that, I would like to know, how can I get Windows XP on the grub menu? Because I know its there (the Windows XP), but I can not boot it from grub. Observation: I already tried update-grub, but it only finds Debian W. and Windows 8.

  • can 'Percona MySQL Data Recovery' be used to recover dropped tables if the datadir filesystem is mounted as /

    - by Tom Geee
    according to Percona: Unmount the filesystem or make it read-only if... You have filesystem corruption OR You have dropped tables in innodb_file_per_table format If I have innodb_file_per_table enabled, and accidently dropped a table, while the datadir is mounted as within the / partition , can data still be recovered? Obviously you can't work with an unmounted root filesystem. Our VPS host has a defaulted filesystem table which we cannot customize. I was wondering in case of any future scenario. edit: would mounting the / filesystem through NFS onto another system as read-only be a workaround? TIA.

  • Partial-stroking / Short-stroking / Half-stroking Hard Drives?

    - by Daniel Magliola
    Could anyone here explain to me what is implied by this term? (I've seen the same thing mentioned with the 3 terms). At first when I read about it, for some reason I understood that it was some way of splitting the bytes across the platters of the disk, which sounded like a good idea and obviously doesn't make sense, because that wouldn't cut disk size in half (and disk are probably already splitting bytes across platters)... The best I've come to understand is that basically instead of creating one partition for the whole size of the disk, you create 2 partitions, and use only one of them, either the one in the "center" or the one in the "rim" of the platters, and since one of the two is faster (people didn't seem to agree on which one was faster), that makes everything better. Am I understanding this correctly? Has anyone tried this with their drives and had a good outcome? Thanks!

  • How to prepare and secure a Macbook Pro for work/office?

    - by sunpech
    I plan to use my Macbook Pro at work/office. Before I do so, I will need to speak to my manager on how to properly prepare and secure it since this is the first Mac that will be regularly used on the network in the office and company intranet. The intranet comprises mostly of PCs running Microsoft Windows XP, Server 2003, and Windows 7. So there's definitely a Microsoft-only culture in the office, and the infrastructure/networking team are mostly unfamiliar with non-Microsoft technology and software. What steps and software would I need to prepare and secure my Macbook Pro for work/office? Antivirus/Spyware software for Mac required/necessary? What options do I have to encrypt files, or possibly the whole drive/partition? What network/firewall settings should be enabled?

  • Cant logon to domain over site-to-site vpn

    - by 3molo
    Tied together branch office with main office over two Cisco ASAs. The (internal) networks on either side can communicate with the other. I can ping, use the DC's DNS service and even join a domain on a new client. I can't however logon, I get the "domain controller is not available" error message on client. I find nothing peculiar in DC's event logs. Sicne it's site-to-site (with ping), it's always up so it should work. No firewall rules (except allow any any) between the two networks (of either side). Main site internal net: 10.10.10.0/24 Branch office net: 10.180.3.0/24 Am I overlooking something here? Where should I start investigating this?d

  • Virtual Box fails my OSes :(

    - by Kingston Town
    I have a little problem with Virtual Box latest version in which i have installed Mint (also latest version).During creation of a new vdi partition I chose settings as default, that is, I don't create any tiny partitions myself. The installation works. But later while the new OS is running (not in Live mode) I try installing/updating new software available, the system automatically fails, it reports an error of DISKFULL, I close the message box then power off my system. Later on I can't boot it up again anymore. It hangs with a black screen and the PAUSE status. I have no idea why. I have installed 2 OSes and both fail at the same error. I doubt something is not right about the current version of VBox. Thank you . My host OS is Windows7 and my Clients are Mint and CentOS
