  • Building a Data Warehouse

    - by Paul
    I've seen tutorials articles and posts on how to build datawarehouses with star and snowflakes schemas, denormalization of OLTP databases fact and dimension tables and so on. Also seen comments like: Star schemas are for datamarts, at best. There is absolutely no way a true enterprise data warehouse could be represented in a star schema, or snowflake either. I want to create a database that will server for reporting services and maybe (if that isn't enough) install analisys services and extract reports and data from cubes. My question was : Is it really necesarry to redesign my current database and follow the star/snowflake schemas with fact and dimension tables ? Thank you

  • Replicating/Synchronizng multiple tables across diffrent Databases on the same instance

    - by Idan
    I have few tables that needed to be replicated/synchronized across several databases in our SQL Server 2008 cluster. I know it's possible to replicate between multiple instances, but I'm looking for replication or synchronization in the same instance between specific tables of databases. The replicaiton/synchronization should happen every half-hour or so, but I don't mind it happening constantly. I can't use DROP the target table and INSERT (copy) the source table since there are many constraints. Reason for this is to not manage in the application layer and write to 2 different databases at the same time. Example: DB1 has T1, T2 and T3 - these are constantly being updated by the application, APP1 running on DB1. DB2 needs to have an updated copy of T1 at all times, also, there is a different application, APP2 runs only on DB2. Both DB1 and DB2 are located on the same instance, INST1. Would it be possible to replicate T1, T2 and T3 from DB1 to DB2 ? Thanks, Idan.

  • Which tool / technology: System management for databases and dependent services

    - by Filburt
    I'm looking for advice on how to enable our team to take down and re-start our company systems for maintainance purposes. The scenario includes several Oracle db machines several MS SQL Server machines with multiple instances windows services (IIS etc.) BizTalk EAI solution Apache and Tomcat instances lots of scheduled tasks on win2003 and win2008 machines (physical and virtual). The main focus is on capture all dependencies between said databases and services and tasks connecting to them. At the moment an enterprise class solution is not an option. We are considering developing a solution driven by PowerShell scripts but I hope for some more suggestions.

  • Weather Logging Software on Windows Home Server

    - by Cruiser
    I'm looking for some weather logging software that I can run as a Windows Home Server add-in, or as a service on my Home Server, so I don't need to log into my Home Server to log weather data. I have an Oregon Scientific WMR918 weather station, and an HP MediaSmart EX485 Windows Home Server. The two are currently connected through a serial bluetooth adapter, but that shouldn't matter as the computer sees it basically as a serial device. I'm currently using Cumulus to log data and upload to Weather Underground, but it is a regular windows application, so I need to remain logged into my Home Server by RDP in order to run the software (I disconnect, but don't log off so the session remains open). Ideally I would like something to run as a service or WHS add-in, so that it runs all the time without logging in, can log data from my WMR918, and can upload to Weather Underground. Thanks!

  • Slow Web Performance on two Windows 2008 R2 Terminal Servers

    - by Frank Owen
    We have two Windows 2008 R2 servers that we use for agents to log into to access our customers systems. Saturday morning we received complaints that on both servers the web is running horribly slow. This happens on all websites and the majority of the time the web site times out trying to load. Other users located at the same site but using their desktop machine do not see any issue. We have rebooted the boxes and checked settings and cannot find the cause. The CPU/Memory/Network/Disk Space use on the server is very low. I thought it might have been a MS update causing the issue but it appears the last update was applied in January. We have rebooted both boxes and I am in process of trying a different browser. Any ideas what could be causing this?

  • How do I check for available "Automatic Updates" via script / cli

    - by Lee
    I asked this on superuser, but I think this may have been a more apropriate place. We are trying to automate server reboots, but one of the "gotchas" we are running into are that they want us to install updates by manually clicking "sure, install updates" during monthly Windows reboots. If I had a way to check to see if updates are in fact waiting, we'd be ok with rebooting automatically via a script and just failing if this is the case. My problem is I can't figure out how to check to see if there are in fact updates waiting to be installed, without logging in. Is there a file or particular service status I can check for? Maybe with Powershell or something similar? The current setting used is "Download updates but do not install automatically"

  • 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.

  • Remote RAID Control in ESXi on a Dell PowerEdge 2950 Using OpenManage

    - by yoyomommy
    I was wondering how one can add a drive into an existing RAID array while ESXi is still running. I have read that you are able to use Dell OpenManage to do this. I have installed OMSA 7.0 on the VMWare ESXi host (5.0 and fully updated) and I've installed OpenManage Essentials on a Windows Server 2008 R2 guest. The issue that I'm having is that OpenManage is unable to see my RAID controller. I have seen videos and photos as parts of guides on how to do this online, so I would assume that the functionality exists and I just have it set up wrong.

  • Connect linux server to VPN server via PPTP

    - by wowpatrick
    I'm trying to connect a Linux (Ubuntu 10.04 LST) server to a VPN server via the PPTP client to an VPN server. I configured the PPTP client as said in the documentation. The connection is correctly added as an interface, but somehow the connection dose not work. ping -I ppp0 google.com dose not return anything and traceroute -i ppp0 only shows the first hop, and then displays nothing. Any ideas of what is going wrong? Incorrect routing configuration? ifconfig output for the configured interface: ppp0 Link encap:Point-to-Point Protocol inet addr:xx.x.xxx.xxx P-t-P:10.0.0.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1496 Metric:1 RX packets:415 errors:0 dropped:0 overruns:0 frame:0 TX packets:468 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:31428 (31.4 KB) TX bytes:32394 (32.3 KB) route output Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface xx.x.x.1 * 255.255.255.255 UH 0 0 0 ppp0 xx.xxx.xxx.xx sp.ip 255.255.255.255 UGH 0 0 0 eth1 192.168.3.0 * 255.255.255.0 U 0 0 0 eth2 192.168.2.0 * 255.255.255.0 U 0 0 0 eth1 default sp.ip 0.0.0.0 UG 100 0 0 eth1

  • How to Disable secondary drive from booting upon restart - Windows

    - by DevCompany
    I had a Windows 2003 Hard Drive on my server and it went bad so I installed a new clean hard drive and installed Windows 2008 R2 on the new clean drive. I moved the old 2003 drive to be used only for general storage on the same computer. It usually boots into Windows 2008 upon a restart, but just sometimes it starts trying to boot the old 2003 drive and causes boot issues(NTDLR Bootloader, and other errors), even though the order of boot preference is set to boot 2008, and NOT 2003. I need to know how to remove any old code that keeps this old drive as a bootable drive. I still want to use it as a secondary drive just dont want to have any boot code on it. hopefully my situation is clear for everyone to get a good response. Thank you...

  • Unable to FTP, any ideas?

    - by Nick
    I'm using Windows Server 2003. I have the FTP services installed, router set to DMZ, and currently Anonymous logins allowed. (I know, security risk, but there's nothing important on there and not worried at the moment) So here's the thing... I can ftp to my computer, list directory, get files etc, BUT only if I'm using the command prompt. If I try to log in using IE or any FTP client it's just timing out. I've tried: username@ipaddress ipaddress username:password@ipaddress and not able to get any of them to work. Anyone have any ideas? Thanks!!!

  • Options for transparent data encryption on SQL 2005 and 2008 DBs.

    - by Dan
    Recently, in Massachusetts a law was passed (rather silently) that data containing personally identifiable information, must be encrypted. PII is defined by the state, as containing the residents first and last name, in combination with either, A. SSN B. drivers license or ID card # C. Debit or CC # Due to the nature of the software we make, all of our clients use SQL as the backend. Typically servers will be running SQl2005 Standard or above, sometimes SQL 2008. Almost all client machines use SQL2005 Express. We use replication between client and server. Unfortunately, to get TDE you need to have SQL Enterprise on each machine, which is absolutely not an option. I'm looking for recommendations of products that will encrypt a DB. Right now, I'm not interested in whole disk encryption at all.

  • How do I network this Windows Failover Cluster and MongoDB Replica Set? (diagram inside)

    - by arex1337
    As you can see, my two Windows Server Failover Cluster (WSFC) nodes have three network interfaces each, which connects them to three different networks : A public network A private network consisting of the WSFC nodes A private network consisting of the WSFC nodes and a machine with the WSFC Quorum Witness File Share Does this network configuration I've planned, make sense? Do I have the "right" number of NICs and networks? I'm thinking the 2nd NIC/network may be unnecessary. My two MongoDB Replica Set nodes also have three network interfaces each - very similar to the previous situation: A public network A private network consisting of the primary and secondary MongoDB Replica Set nodes A private network consisting of the primary, secondary and arbiter MongoDB Replica Set nodes Does this network configuration, make sense? Do I have the "right" number of NICs and networks? I'm thinking the 2nd NIC/network may be unnecessary. Here is the simpler version I'm considering: UPDATE:

  • Hyper-v vs Virtualbox

    - by user53864
    I am using Oracle VirtualBox for ubuntu guest virtual servers on windows server 2008 R2. I'm in a plan to migrate(stop using virtualbox) from VirtualBox to Hyper-V. I guess many are using hyper-v virtualization and have good control over it and could help me here in clarifying few things. The reason I use Virtualbox is it's open source and the reason for migrating is that if hyper-v support any additional feature which virtualbox doesn't(and I couldn't migrate VBox vms along with all the snapshots). I have following questions to get it clarified. Does hyper-v require any licence or is limited to running particular number of virtual machines?. Is hyper-v capable to export/import VMs along with all the snapshots? Is it possible to run HeadLess VMs like it's done with VirtualBox? Does hyper-v recognize VDI/VMDK? Anybody can suggest me anything?. Thanks!

  • Methods to transfer files from Windows server to linux server

    - by Raze2dust
    Hi, I need to transfer webserver-log-like-files containing periodically from windows production servers in the US to linux servers here in India. The files are ~4 MB in size each and I get about 1 file per minute. I can take about 5 mins lag between the files getting written in windows and them being available in the linux machines. I am a bit confused between the various options here as I am quite inexperienced in such design: I am thinking of writing a service in C#.NET which will periodically archive, compress and send them over to the linux machines. These files are pretty compressible. WinRAR can convert 32 MB of these files into a 1.2 MB archive. So that should solve the network transfer speed issue. But then how exactly do I transfer files to linux? I could mount linux drive on windows server using samba, or should I create an ftp server, or send the file serialized as a POST request. Which one would be good? Also, I have to minimize the load on the windows server. Mount the windows drive on linux instead. I could use the mount command or I could use samba here (What are the pros and cons of these two?). I can then write the compressing and copying part in linux itself. I don't trust the internet connection to be very stable, so there should be a good retry mechanism and failure protection too. What are the potential gotchas in these situations, and other points that I must be worried about? Thanks, Hari

  • Slow write speeds on new Gigabit home file server

    - by Ryan Holder
    So I finally got all my parts delivered to setup a home file/backup server this week. It's currently running Ubuntu Server and I'm using Samba to share files on my network. The server currently has a 2TB WD Green drive in it connected to a Asus M5A78L-M This is then connected via CAT6a to my new Gigabit switch (TP-Link TL-SG1005D). My home desktop is then also connected to this switch and again also through CAT6a cable. Currently when transfering files I will get a perfect 100MB/s read from the server to my Windows machine. When copying from my Windows machine to the server I get around 30/38MB/s. I know this drive is capable is faster speeds so would anybody have an idea of where the bottleneck is? Any help would be greatly appreciated :) EDIT: I have found ftp's write speed is much closer to what my Samba read speed is so I'm going to give it a guess that is a software problem rather than hardware

  • Finding Locked Out Users

    - by Bart Silverstrim
    Active Directory up to 2008 network (our servers are a mix of 2008, 2003...) I'm looking for a quick way to query AD to find out what users are locked out, preferably from a batch or script file, to monitor for possible issues with either user accounts being attacked by an automated attack or just anomalies in the network. I've Googled and my Google-fu has failed; I found a query off Microsoft's own knowledgebase that cites a string to use on Server 2003 with the management snap-in's saved queries (http://support.microsoft.com/kb/555131) but when I entered it, the query returned 400 users that a spot-check showed did NOT have a checkmark in the "Account is locked out" box under "account." In fact, I don't see anything wrong with their accounts. Is there a simple utility (wisesoft bulkadusers apparently uses this method behind the scenes, since it's results were also wrong) that will give a count of users and possibly their user object names? Script? Something?

  • slow disk writes between host and guest

    - by Jure1873
    I've got a ubuntu (server kernel) on a amd x4, 4gb ram, 2x seagate sata 1 tb disks for testing virtual machines and the write performance is very slow. The two disks are in a software raid1 array, one small boot ext3 partition, 10gb system partition and the rest is a xfs partition (about 980) gb for data (virtual machines). If I'm copying files from the virtual machine to the host with rsync or scp the copy frequently stalls or goes at about 1mb/s. What's wrong? I've tried disabling barriers on xfs, increased logbufs, allocsize, but it seems nothing helps. The strange thing is that await (for example during copying) for sda is usually under 100, while for sdb is around 400. Any ideas on what could be wrong / what could I do to improve this setup?

  • Web & SQL Hosting 32 vs. 16 GB of ram

    - by TravisK
    I'm in the market for a new dedicated host for my website. My question is I can pay more to upgrade to 32GB of RAM, but it seems overkill for my website right now, in fact, 16GB seems a little overkill. However, I run a lot of pretty intense full text searches for my site. I'm wondering if SQL Server would benefit, or could it be configured to use the 32 GB of RAM if I purchase the additional to help speed things up? I am assuming that most of my latency is caused by disk I/O and that for the extra money spent on RAM, I might not see any improvement in overall speed?

  • changing permissions for a network share takes longer on win2008 than on win2003, why is that?

    - by HugoRune
    Given a network share accessible for "everyone" in the domain, containing several 1000 files and folders When I change permissions for this share from read/write to only read (or vice versa) on windows 2003, the change takes effect instantly. When I do the same on a share on Windows 2008, the dialog stays open for a long time before closing when I click on OK, and the server appears to be accessing a lot of files. What is the reason for this delay? Does Windows 2008 also change ntfs permissions for all files inside the share? If so, why doesn't win2003 have to do that? I do not mind the delay, after all I do not have to change this stuff very often, but I am curious. What are the differences between 2003 and 2008 in this regard?

  • Expire windows user (license) after some time according to first login instead of a solid expiration date

    - by smhnaji
    In a project, we have lots of Windows user that have bought licenses for 1 month, 2 month,... 1 year and so... CURRENT SITUATION (WHAT I DON'T WANT): When users are created and added to the OS, a solid expiration date is given. WHAT I WANT: Users' expiration date should be calculated automatically after first login. The user might not need his account right when purchases the license. In another words: When a license is purchased at Jan 1, he should use the license until Feb 1. No matter whether he really logs in or not. He cannot come Feb 5 and begin using his license because that has expired then. What I want is that when he comes at Feb 5 and begins using, the license update until March 5. Environment: Windows Server 2012

Prevent locked or roaming user profiles that cannot be found on the computer from logging on 2. Do not cache copies of locked or roaming user profiles for users who have previously logged on to this computer 3. Do not allow Windows to compute and store passwords using LAN Manager Hash values 4. Do not store usernames or passwords used to log on to the Windows Live ID or the domain 5. Prevent users from creating folders and files on drive C:\ 6. Lock profile to prevent the user from making permanent changes 7. Remove the Control Panel, Printer and Network Settings from the Classic Start menu 8. Remove the Favorites icon 9. Remove the My Network Places icon 10. Remove the Frequently Used Program list 11. Remove the Shared documents folder from My Computer 12. Remove control Panel icon 13. Remove the Set Program Access and Defaults icon 14. Remove the Network Connection(Connect To)icon 15. Remove the Printers and Faxes icon 16. Remove the Run icon 17. Prevent access to Windows Explorer features: Folder Options, Customize Toolbar, and the Notification Area 18. Prevent access to the taskbar 19. Prevent access to the command prompt 20. Prevent access to the registry editor 21. Prevent access to the Task Manager 22. Prevent access to Microsoft Management Console utilities 23. Prevent users from adding or removing printers 24. Prevent users from locking the computer 25. Prevent password changes (also requires the Control Panel icon to be removed) 26. Disable System Tools and other management programs 27. Prevent users from saving files to the desktop 28. Hide A Drive 29. Hide B Drive 30. Hide C Drive 31. Prevent changes to Internet Explorer registry settings 32. Empty the Temporary Internet Files folder when Internet Explorer is closed 33. Remove Internet Options 34. Remove General tab in Internet Options 35. Remove Security tab in Internet Options 36. Remove Privacy tab in Internet Options 37. Remove Content tab in Internet Options 38. Remove Connections tab in Internet Options 39. Remove Programs tab in Internet Options 40.

  • windows print service

    - by user1631171
    Hi my college has a HP color printer that can be used to print both A3 and A4 size color printouts. It is connected to a windows 2008 print server. The windows event viewer provides the status of printouts using event id 307. I would like to know if it is possible to find out if an A3 page was printed or A4 page was printed. Is this information also logged in windows event viewer. Or is there any other event id that captures this information. Also the number of copies printed should be captured in event id 805. I have read in some forums that sometimes the value is wrong. Please provide me some information on this. Thanks in advance.
