  • Search and Browse Database Objects with Oracle SQL Developer

    - by thatjeffsmith
    I was tempted to throw in another Dora the Explorer Map reference here, but I came to my senses.Having trouble finding something? Maybe you’re just getting older? I know I am. But still, it’d be nice if my favorite database tool could help me out a bit. Hmmm, what’s this ‘Find Database Object‘ thing over here…sounds like a search mechanism of some sort? You can access this panel from the ‘View‘ menu. It’s a good bit down the screen, so I don’t blame you if you haven’t seen it before. It makes finding ‘stuff’ in your database so much easier. Let’s say I want to find my ‘beer’ objects. I simply need to type my search string and the context (in this case I want it to search EVERYTHING), and hit enter. The search results are listed below and clicking on an object automatically opens it! I know it seems very simple, but I get asked this question a LOT. It will even search through your PL/SQL code! Finding too much? Be sure to toggle off the ‘%’ wildcard check box before doing a search. Working on a Project? I bet you use common column names, or codes, throughout your tables. You could take advantage of this knowledge and use the Find Database Object panel as a substitute connection tree or schema browser. Working on your HR project and want to look at your employee objects? Do a column search for your column ID/key. Sometimes thinking outside the box actually works! Don’t be afraid to tackle a problem from a weird angle, or re-purpose your tools. I do it all the time And I drive the developers nuts trying to do things with the tools they were never designed to do. But I digress. Back to your coding!

  • SQLOS and Cloud Infrastructure sessions at PASS Summit 2012

    - by SQLOS Team
    The SQL Pass Summit 2012, the largest yet, is in full swing. Here's a summary of the sessions this week on cloud infrastructure and SQLOS topics. Some of these were today, and you can catch the recordings. One more session takes place on Friday covering SQL Server solution patterns in Windows Azure VMs... Also, catch Thursday's keynote with Quentin Clark which will feature a cool IaaS demo!   SQL Server in Windows Azure VM Sessions CLD-309-A SQLCAT: Best Practices and Lessons Learned on SQL Server in an Azure VM Steve Howard, Arvind Ranasaria - Wednesday 11/6 10:15 This session looked at some best practices to optimize Networking, Memory, Disk IO and high availability based on lessons learned during SQLCat work with customer deployments. Well worth catching the recording.   SQL Server in Azure VM patterns: Hybrid Disaster Recovery, data movement and BI Guy Bowerman, Peter Saddow, Michael Washam, Ross LoForte - Friday 11/9 9:45 Rm 613 [Note: In the guides this has an outdated title.] This session has a focus on SQL Server Azure VM solutions. Starting with the basics and then going deeper into: - New features in the Microsoft Assessment and Planning Toolkit 8.0 to help plan and size SQL VM migrations.- A Look at a Windows Azure VM SQL Server app making use of load balancing and SQL Server high availability features.- A BI case study running SQL BI components in Azure VMs and making use of Windows 8 tiles.- A training class in a VM case study.   SQLOS Sessions DBA-500-HD Inside SQLOS 2012 (half-day session) Bob Ward - Wednesday 11/6 1:30pm Bob Ward from CSS applies his wealth of experience to look at the internals of SQLOS and what's changed in the various SQL 2012 components, including memory, resource governor, scheduler.   DBA-403-M: SQLCAT: Memory Manager Changes in SQL Server 2012 Gus Apostol, Jerome Halmans - 1:30pm Covers the redesigned SQLOS memory manager in SQL Server 2012 including the new page allocator for any size pages (and all that implies), DMVs, demo's. Not sure why this was placed at the same time as the SQLOS half-day session, but since it's recorded it's available for catch-up.   - Guy   Originally posted at http://blogs.msdn.com/b/sqlosteam/

  • SQL Server 2008 Compression

    - by Peter Larsson
    Hi! Today I am going to talk about compression in SQL Server 2008. The data warehouse I currently design and develop holds historical data back to 1973. The data warehouse will have an other blog post laster due to it's complexity. However, the server has 60GB of memory (of which 48 is dedicated to SQL Server service), so all data didn't fit in memory and the SAN is not the fastest one around. So I decided to give compression a go, since we use Enterprise Edition anyway. This is the code I use to compress all tables with PAGE compression. DECLARE @SQL VARCHAR(MAX)   DECLARE curTables CURSOR FOR             SELECT 'ALTER TABLE ' + QUOTENAME(OBJECT_SCHEMA_NAME(object_id))                     + '.' + QUOTENAME(OBJECT_NAME(object_id))                     + ' REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE)'             FROM    sys.tables   OPEN    curTables   FETCH   NEXT FROM    curTables INTO    @SQL   WHILE @@FETCH_STATUS = 0     BEGIN         IF @SQL IS NOT NULL             RAISERROR(@SQL, 10, 1) WITH NOWAIT           FETCH   NEXT         FROM    curTables         INTO    @SQL     END   CLOSE       curTables DEALLOCATE  curTables Copy and paste the result to a new code window and execute the statements. One thing I noticed when doing this, is that the database grows with the same size as the table. If the database cannot grow this size, the operation fails. For me, I first ended up with orphaned connection. Not good. And this is the code I use to create the index compression statements DECLARE @SQL VARCHAR(MAX)   DECLARE curIndexes CURSOR FOR             SELECT      'ALTER INDEX ' + QUOTENAME(name)                         + ' ON '                         + QUOTENAME(OBJECT_SCHEMA_NAME(object_id))                         + '.'                         + QUOTENAME(OBJECT_NAME(object_id))                         + ' REBUILD PARTITION = ALL WITH (FILLFACTOR = 100, DATA_COMPRESSION = PAGE)'             FROM        sys.indexes             WHERE       OBJECTPROPERTY(object_id, 'IsMSShipped') = 0                         AND OBJECTPROPERTY(object_id, 'IsTable') = 1             ORDER BY    CASE type_desc                             WHEN 'CLUSTERED' THEN 1                             ELSE 2                         END   OPEN    curIndexes   FETCH   NEXT FROM    curIndexes INTO    @SQL   WHILE @@FETCH_STATUS = 0     BEGIN         IF @SQL IS NOT NULL             RAISERROR(@SQL, 10, 1) WITH NOWAIT           FETCH   NEXT         FROM    curIndexes         INTO    @SQL     END   CLOSE       curIndexes DEALLOCATE  curIndexes When this was done, I noticed that the 90GB database now only was 17GB. And most important, complete database now could reside in memory! After this I took care of the administrative tasks, backups. Here I copied the code from Management Studio because I didn't want to give too much time for this. The code looks like (notice the compression option). BACKUP DATABASE [Yoda] TO              DISK = N'D:\Fileshare\Backup\Yoda.bak' WITH            NOFORMAT,                 INIT,                 NAME = N'Yoda - Full Database Backup',                 SKIP,                 NOREWIND,                 NOUNLOAD,                 COMPRESSION,                 STATS = 10,                 CHECKSUM GO   DECLARE @BackupSetID INT   SELECT  @BackupSetID = Position FROM    msdb..backupset WHERE   database_name = N'Yoda'         AND backup_set_id =(SELECT MAX(backup_set_id) FROM msdb..backupset WHERE database_name = N'Yoda')   IF @BackupSetID IS NULL     RAISERROR(N'Verify failed. Backup information for database ''Yoda'' not found.', 16, 1)   RESTORE VERIFYONLY FROM    DISK = N'D:\Fileshare\Backup\Yoda.bak' WITH    FILE = @BackupSetID,         NOUNLOAD,         NOREWIND GO After running the backup, the file size was even more reduced due to the zip-like compression algorithm used in SQL Server 2008. The file size? Only 9 GB. //Peso

  • Configurable tables in sql database

    - by dot
    I have the following tables in my database: Config Table: ====================================== Start_Range | End Range | Config_id 10 | 15 | 1 ====================================== Available_UserIDs ========================== ID | UserID | Used_YN | 1 | 10 | t | 1 | 11 | f | 1 | 12 | f | 1 | 13 | f | 1 | 14 | f | 1 | 15 | f | ========================== Users ========================== UserId | FName | LName | 10 |John | Doe | ========================== This is used in a reservation system of sorts... which lets an administrator specify a range of numbers that will be assigned to users in the config table. Once the range has been defined, the system then populates the Available_userIDs table with all the numbers in between the range, and sets the Used_YN flag to false As users sign up, they grab the next user_id number that's not in use... and reserve it. Then the system adds a record to the Users table. Once the admin has specified a range, it is possible that they can change it. For example, they can start with 10-15... and then when the range is used up, they should be able to specify another range like 16 - 99. I've put a unique constraint on the Available_UserIDs table, as well as on the Users table - to ensure that UserIds can't be duplicated. My questions are as follows: What's the best way to prevent the admins from using a range that's already in use? I thought of the following options: -- check either the Users table to see if the start range or ending range numbers are being used. If they are, assume that all the numbers in between are in use too, and reject the range. -- let them specify whatever they want, try to populate the Available_UserIDs table. If there are duplicates, just ignore that specific error message from the database and continue on. How do I find gaps in the number ranges? For example, if they specify 10-15, and then 20-25, it'd be nice to be able to somehow suggest on my web page that 16-19 is currently available. I found this article: http://stackoverflow.com/questions/1312101/how-to-find-a-gap-in-running-counter-with-sql But it only seems to return the first available number... so in my example above, it would only return the number 16. I'm sure there's a simpler way to do things that I'm overlooking!

  • How to run VisualSVN Server on port 443 running IIS on same server?

    - by Metro Smurf
    Server 2008 R2 SP1 VisualSVN Server 2.1.6 The IIS server has about 10 sites. One of them uses https over port 443 with the following bindings: http x.x.x.39:80 site.com http x.x.x.39:80 www.site.com https x.x.x.39:443 VisualSVN Server Properties server name: svn.SomeSite.com server port: 443 Server Binding: x.x.x.40 No sites on IIS are listening to x.x.x.40. When starting up VisualSVN server, the following errors are thrown: make_sock: could not bind to address x.x.x.40:443 (OS 10013) An attempt was made to access a socket in a way forbidden by its access permissions. no listening sockets available, shutting down When I stop Site.com on IIS, then VisualSVN Server starts up without a problem. When I bind VisualSVN server to port 8443 and start Site.com, then VisualSVN Server starts without a problem. My goal is to be able to access the VisualSvn Server with a normal url, i.e., one that does't use a port number in the address: https://svn.site.com vs https://svn.site.com:8443 What needs to be configured to allow VisualSVN Server to run on port 443 with IIS running on the same server? Edit / Answer The answer provided by Ivan did point me in the right direction. For anyone else running into this, here is a bit more information. Even though my IIS had no bindings set to the IP address I am using for VisualSvn, IIS will still take the IP address hostage unless IIS is explicitly told which IP addresses to listen to. There is no GUI in Win Server 2k8 to configure the IP addresses for IIS to listen; by default, IIS listens to all IP addresses assigned to the server. The following will help configure IIS to only listen to the IP addresses you want: open a command prompt enter: netsh enter: http enter: show iplisten -- this will show a table of the IP addresses IIS is listening to. By default, the table will be empty (I guess this means IIS listens to all IP's) For each IP address IIS should listen to, enter: add iplisten ipaddress=x.x.x.x enter: show iplisten -- you should now see all the IP addresses added to the listening table. Exit and then reset IIS. Each of these commands can also be run directly, i.e., netsh http show iplisten If you need to delete an IP address from the listening table: open a command prompt enter: netsh enter: http enter: delete iplisten ipaddress=x.x.x.x Exit and then reset IIS.

  • Help Installing SQL Server 2008 Express Edition

    - by Jordan S
    Ok I am running Windows 7, 64 bit. I cleaned of SQL server 2005 completely off my system leaving only SQL Compact Edition. I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=01af61e6-2f63-4291-bcad-fd500f6027ff&displaylang=en and installed SQL Server 2008 Express Edition Service Pack 1. After the install, under my start bar menu all i have for SQL configuration tools are the Configuration Manager, Error and Usage Reporting and the Install Center. I don't have the SQL Managment Studio. So I went here http://www.microsoft.com/downloads/details.aspx?FamilyID=08e52ac2-1d62-45f6-9a4a-4b76a8564a2b&displaylang=en and downloaded the SQL Server 2008 Management Studio Express but when I try to install it I get a warning says This program has known compatibility issues and that I need to Install SQL Server 2008 Service Pack 1. I thought that is what I installed. So, I tried to continue running the install but I then get an error message that says Invoke or BeginInvoke can not be called on a Form before it is opened... How can I check if Service pack 1 is installed or not? What should I do? Also I rebooted my system and checked for Windows Updates and it says that Windows it up to date.

  • SQL 2005 Install completly broken on laptop.

    - by ProfKaos
    My problems started when I set up an exploratory domain controller at home. During that process, I changed the name of my laptop, from 'erisia' to 'erisia-laptop', and this resulted in me losing my admin account on SQL Server 2005 on my laptop. SQL Server seems to store the machine name as part of the user name, so now my local admin account is 'erisia-laptop\brady', which SQL server didn't recognise. I thought I'd cut my losses and just re-install SQL 2005, but the first install was aborted, so I tried a complete uninstall, followed by the new install. The latter didn't work while the former worked way too well. Now every attempt at installing SQL Server 2005 SP2 on my laptop running XP SP3 ends in sadness, with MSXML6 being the cause, because it won't install on this OS version. WTF? Does anyone know what I can do to get SQL 2005 installed? It's the only full admin DB tool I have. SQL 2008 Express that installed with VS 2010 Beta 2 doesn't allow much server admin.

  • DNS and RPC Unavailable

    - by Berek Bryan
    I have a server that is host a MSSQL database and some other server related tasks. The server communicaties with a large number of devices. The devices send data to the server. The communication links are down between the devices on the intranet and to the outside world. However it seems I can ping and can be pinged from machines on the same switch. This includes the DNS Servers. When I run, C:\ipconfig /registerdns I get RPC Server is Unavailable. So, it seems that the server can not verify the DNS server. Both DNS server are up and running. No other machines are affected on the network.

  • Suggestions on the best home server rack cabinet

    - by allentown
    I have a lot of gear in a colocation facility right now. Some of it is going to come home with me now. I do not know anything about the "rack mount" side of the industry. I lease a rack, and I put my stuff in it. I have a few 1U boxes, a few 2U boxes, and a few 4U boxes. 1U switch. One is a new Xserve, which means it is deep. I think I can get by with around 12U to 18U. I want to keep it as small as possible, since I do not have a lot of spare space at my home. I will not be able to bolt to the wall, floor etc, so it should not be tall. This is something I would love to more or less just be a box that sits on the floor but gives me the ability to mount nicely, do nice cable management etc. Are the "post" style racks junk? I am liking the open space, and the no limitations on depth of something like this: http://www.rackmountsolutions.net/images/products/Martin-relay-rack.jpg However, that thing is way too tall, and probably way too expensive. I am looking to be around $300.00 or less. More if I have to, though I would prefer not to. These look near perfect: (See comment for this link, the system will not let me post a second url) but I am worried the Xserve will not fit in it. If anyone has any good links, or website recommendations of good past experience, I would appreciate it. I am almost considering that I may be able to build something with random scraps of stuff at Home Depot as well.

  • SQL Server Replication Agent priority

    - by Wikser
    Every hour a server replicates SQL server data with some external web server. During this time, which takes about 2-5minutes, the database seriously slows down. Colleagues, which work with the front end applications of that on another terminal server, even regularly start complaining. The databases are also synchroniously mirrored (via SQLServer mirroring, no replication) to a third server. Note that 99% of the data is replicated outgoing, so the server should rarely need to update its data. As the (merge and transactional) replication tasks are not time-critical, I would like to reduce their priority or somehow slow them down, so they don't affect the database performance that much. How would you implement that?

  • Connecting to SQL Server on Parallels Desktop with PHP

    - by Zen Savona
    well I recently bought a Mac and am using it as my primary computer. Because I am required to work with MSSQL via PHP, I have installed Parallels Desktop and run Server 2008 R2 on it. I am using the same mixed mode authentication which I previously had on windows. When I attempt to connect to the server with PHP using either a new test file or my old code, it just doesn't find the server. I have tried running PHP on the XP install with parallels, and using the hostname as COMPUTERNAME\SQLEXPRESS, LOCALIP\SQLEXPRESS localhost localip etc, PHP never finds the server. Also note that I can connect to the database server using Management Studio without problems, so SQL Server is running. Please note that both PHP and MSSQL are running within the virtualised environment. Any contribution is appreciated

  • I'm trying to grasp the concept of creating a program that uses a SQL Server database, but I'm used

    - by Sergio Tapia
    How can I make a program use a SQL Server database, and have that program work on whatever computer it's installed on. If you've been following my string of questions today, you'd know that I'm making an open source and free Help Desk suite for small and medium businesses. The client application. The client application is a Windows Forms app. On installation and first launch on every client machine, it'll ask for the address of the main Help Desk server. The server. Here I plan to handle all incoming help requests, show them to the IT guys, and provide WCF services for the Client application to consume. My dilemma lies in that, I know how to make the program run on my local machine; but I'm really stumped on how to make this work for everyone who wants to download and install the server bit on their Windows Server. Would I have to make an SQL Script and have it run on the MS SQL server when a user wants to install the 'server' application? Many thanks to all for your valuable time and effort to teach me. It's really really appreciated. :) Edit: To clarify, each business will have their server completely separate from me. I will have no access whatsoever to them nor will they be in any way connected to me. (I don't know why I should clarify this :P ) So, assuming the have ABSOLUTELY NO DATABASE SERVER installed; what can I do?

  • Uploading files to varbinary(max) in SQL Server -- works on one server, not the other

    - by pjabbott
    I have some code that allows users to upload file attachments into a varbinary(max) column in SQL Server from their web browser. It has been working perfectly fine for almost two years, but all of a sudden it stopped working. And it stopped working on only the production database server -- it still works fine on the development server. I can only conclude that the code is fine and there is something up with the instance of SQL Server itself. But I have no idea how to isolate the problem. I insert a record into the ATTACHMENT table, only inserting non-binary data like the title and the content type, and then chunk-upload the uploaded file using the following code: // get the file stream System.IO.Stream fileStream = postedFile.InputStream; // make an upload buffer byte[] fileBuffer; fileBuffer = new byte[1024]; // make an update command SqlCommand fileUpdateCommand = new SqlCommand("update ATTACHMENT set ATTACHMENT_DATA.WRITE(@Data, NULL, NULL) where ATTACHMENT_ID = @ATTACHMENT_ID", sqlConnection, sqlTransaction); fileUpdateCommand.Parameters.Add("@Data", SqlDbType.Binary); fileUpdateCommand.Parameters.AddWithValue("@ATTACHMENT_ID", newId); while (fileStream.Read(fileBuffer, 0, fileBuffer.Length) > 0) { fileUpdateCommand.Parameters["@Data"].Value = fileBuffer; fileUpdateCommand.ExecuteNonQuery(); <------ FAILS HERE } fileUpdateCommand.Dispose(); fileStream.Close(); Where it says "FAILS HERE", it sits for a while and then I get a SQL Server timeout error on the very first iteration through the loop. If I connect to the development database instead, everything works fine (it runs through the loop many, many times and the commit is successful). Both servers are identical (SQL Server 9.0.3042) and the schemas are identical as well. When I open Activity Monitor right after the timeout to see what's going it, it says the last command is (@Data binary(1024),@ATTACHMENT_ID decimal(4,0))update ATTACHMENT set ATTACHMENT_DATA.WRITE(@Data, NULL, NULL) where ATTACHMENT_ID = @ATTACHMENT_ID which I would expect but it also says it has a status of "Suspended" and a wait type of "PAGEIOLATCH_SH". I looked this up and it seems to be a bad thing but I can't find anything specific to my stuation. Ideas?

  • How to push changes from Test server to Live server?

    - by anonymous
    As a beginner, I finally noticed the issue with making changes to the live server I've been working on, now that I have a couple users on it, since I bring it down so often. I created an EC2 image of my live server and set up a separate instance on EC2, so now I have 2 EC2 instances, Stage and Production. I set up GitHub and push changes to stage and test my code there, and when it's all done and working, I push it to the production branch, and everything is good. And there is a slight issue here since I name my files config_stage.js and config_production.js and set up .gitignore on each server, and in my code, I would have it read the ENV flags and set up the appropriate configs, is this the correct approach? And my main question is: how do you keep track of non-code changes to the server? For example, I installed HAProxy, Stunnel, Redis, MongoDB and several other things onto the Stage server for testing and now that it's all working and good, how do I deploy them to production? Right now, I'm just keeping track of everything I installed and copying configuration files over, which is very tedious and I'm afraid I may have missed a step somewhere. Is there a better way to port these changes over from my test server to my live server?

  • Olympics data available for all on Windows Azure SQL Database and Power View

    - by jamiet
    Are you looking around for some decent test data for your BI demos? Well, if so, Microsoft have provided some data about all medals won at the Olympics Games (1900 to 2008) at OlympicsData workbook - Excel, SSIS, Azure sample; it provides analysis over athletes, countries, medal type, sport, discipline and various other dimensions. The data has been provided in an Excel workbook along with instructions on how to load the data into a Windows Azure SQL Database using SQL Server Integration Services (SSIS). Frankly though, the rigmarole of standing up your own Windows Azure SQL Database ok, SQL Azure database, is both costly (SQL Azure isn’t free) and time consuming (the provided instructions aren’t exactly an idiot’s guide and getting SSIS to work properly with Excel isn’t a barrel of laughs either). To ease the pain for all you BI folks out there that simply want to party on the data I have loaded it all into the SQL Azure database that I use for hosting AdventureWorks on Azure. You can read more about AdventureWorks on Azure below however I’ll summarise here by saying it is a SQL Azure database provided for the use of the SQL Server community and which is supported by voluntary donations. To view the data the credentials you need are: Server mhknbn2kdz.database.windows.net  Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly Type those into SSMS and away you go, the data is provided in four tables [olympics].[Sport], [olympics].[Discipline], [olympics].[Event] & [olympics].[Medalist]: I figured this would be a good candidate for a Power View report so I fired up Excel 2013 and built such a report to slice’n’dice through the data – here are some screenshots that should give you a flavour of what is available: A view of all the available data Where do all the gymastics medals go? Which countries do top ten all-time medal winners come from? You get the idea. There is masses of information here and if you have Excel 2013 handy Power View provides a quick and easy way of surfing through it. To save you the bother of setting up the Power View report yourself you can have the one that I took these screenshots from, it is available on my SkyDrive at OlympicsAnalysis.xlsx so just hit the link and download to play to your heart’s content. Party on, people! As I said above the data is hosted on a SQL Azure database that I use for hosting “AdventureWorks on Azure” which I first announced in March 2013 at AdventureWorks2012 now available for all on SQL Azure. I’ll repeat the pertinent parts of that blog post here: I am pleased to announce that as of today … [AdventureWorks2012] now resides on SQL Azure and is available for anyone, absolutely anyone, to connect to and use for their own means. This database is free for you to use but SQL Azure is of course not free so before I give you the credentials please lend me your ears eyes for a short while longer. AdventureWorks on Azure is being provided for the SQL Server community to use and so I am hoping that that same community will rally around to support this effort by making a voluntary donation to support the upkeep which, going on current pricing, is going to be $119.88 per year. If you would like to contribute to keep AdventureWorks on Azure up and running for that full year please donate via PayPal to [email protected] Any amount, no matter how small, will help. If those 50+ people that retweeted me beforehand all contributed $2 then that would just about be enough to keep this up for a year. If the community contributes more than we need then there are a number of additional things that could be done: Host additional databases (Northwind anyone??) Host in more datacentres (this first one is in Western Europe) Make a charitable donation That last one, a charitable donation, is something I would really like to do. The SQL Community have proved before that they can make a significant contribution to charitable orgnisations through purchasing the SQL Server MVP Deep Dives book and I harbour hopes that AdventureWorks on Azure can continue in that vein. So please, if you think AdventureWorks on Azure is something that is worth supporting please make a contribution. I’d like to emphasize that last point. If my hosting this Olympics data is useful to you please support this initiative by donating. Thanks in advance. @Jamiet

  • Dedicated server: managed hosting or manage it myself?

I think there is some reluctance to not having managed hosting since a managed host in effect takes responsibility for your server, whereas any hardware or security issues with a server that we manage would mean we are forced to hold our hands up when a client site goes down.

  • Server Setups for Agencies [closed]

    - by styks1987
    We are considering consolidating our server administration by cutting down on the number of systems we currently use to manage all our websites(~65 websites). Currently we have a testing server and 3 production servers. (2 - cherokee(linode), 1 - apache (mt)) We don't have a dedicated server admin, so I am stuck with managing all these servers, and as a developer, I don't want to deal with all the server hassle. So my main goal is to cut down on the time spent messing with the servers. We have looked at Pagoda Box and AppFog as possibilities. I am not sure if Pagoda Box would be cost effective. With 65+ websites we may end up paying anywhere from 0 to $50+ per website per month. Right now we page about $250 per month for the 4 VPS servers mentioned above. We already use Capistrano for deployment. I have the opportunity to completely overhaul the entire setup and I would like some feedback on where you found your information for large scale server management or how you currently do it. Articles are welcome. In summary: What is new (past 2 years) in simple server management arena? If you work at an agency or have had agency experience, how do/did you manage your sites? a. What is the level of effort for SSL, new site setup, database management, and extension management. b. How did you handle datacenter outages. Anyone with Pagoda Box experience, do you like it and did you have problems with Wordpress, Cakephp, Drupal, Expression Engine or Magento? a. Is it expensive for you? b. How has server uptime been? Your direction and comments are greatly appreciated.

  • 2 Servers setup for redundency, backup

    - by minal
    I presently have 1 dedicated virtual server running my website/blog/mail, etc. This is on Hyper-V with 512MB RAM. Windows Web2008. With the VM, I have these running within it: SmarterMail – for emails MS DNS – I have my own nameservers on this server SQL Express IIS7 2 IP Address I have now leased 2 physical servers : P4 2.6Ghz 1GB RAM 80GB HDD. With these new servers, I get 2 IPs per server as well. These are running Windows 2008 Standard. With the VM the HDD was obviously on a RAID setup so I was not worried about hardware issues as it fell on the provider to manage. However, with the new servers the HDD is not RAID’d, hence my concern is that if it fails I need a backup position. What would be the most ideal setup to go for? I am thinking: Server 1: (Web/PrimaryDNS) DNS – NS1 SQL Express – OFF turn on when required, ie. Server2 is down SmarterMail – OFF turn on when required, ie. Server2 is down IIS 7 Server2:(SQL/Backup) DNS – NS2 SQL Web Edition SmarterMail IIS 7 How can I set it up so that if 1 goes down I can have everything on 2 instantly or by manual switching over. I am confused as other DNS servers will cache the web servers IP address for requests, and if that server goes down, the backup server will have a different IP. How do I make this work? I will be doing routine backups, in which case I will keep copies of backups on both servers. If I am copying the same stuff on both servers like a mirror then I am losing on using the true performance out of it. It's like 1 server is always on standby. Ideally I want SQL and web on 2 diff machines for best performance. If Server1 goes down, I should be able to switch to Server2 fairly easily. I don't have a problem with manual intervention to start the sql/mail services, etc. In terms of scalabilty, the VM has coped pretty well to date. Moving forward the SQL and IIS workload is going to double pretty quickly. Some ideas would be great.

  • Enabling Kerberos Authentication for Reporting Services

    - by robcarrol
    Recently, I’ve helped several customers with Kerberos authentication problems with Reporting Services and Analysis Services, so I’ve decided to write this blog post and pull together some useful resources in one place (there are 2 whitepapers in particular that I found invaluable configuring Kerberos authentication, and these can be found in the references section at the bottom of this post). In most of these cases, the problem has manifested itself with the Login failed for User ‘NT Authority\Anonymous’ (“double-hop”) error. By default, Reporting Services uses Windows Integrated Authentication, which includes the Kerberos and NTLM protocols for network authentication. Additionally, Windows Integrated Authentication includes the negotiate security header, which prompts the client to select Kerberos or NTLM for authentication. The client can access reports which have the appropriate permissions by using Kerberos for authentication. Servers that use Kerberos authentication can impersonate those clients and use their security context to access network resources. You can configure Reporting Services to use both Kerberos and NTLM authentication; however this may lead to a failure to authenticate. With negotiate, if Kerberos cannot be used, the authentication method will default to NTLM. When negotiate is enabled, the Kerberos protocol is always used except when: Clients/servers that are involved in the authentication process cannot use Kerberos. The client does not provide the information necessary to use Kerberos. An in-depth discussion of Kerberos authentication is beyond the scope of this post, however when users execute reports that are configured to use Windows Integrated Authentication, their logon credentials are passed from the report server to the server hosting the data source. Delegation needs to be set on the report server and Service Principle Names (SPNs) set for the relevant services. When a user processes a report, the request must go through a Web server on its way to a database server for processing. Kerberos authentication enables the Web server to request a service ticket from the domain controller; impersonate the client when passing the request to the database server; and then restrict the request based on the user’s permissions. Each time a server is required to pass the request to another server, the same process must be used. Kerberos authentication is supported in both native and SharePoint integrated mode, but I’ll focus on native mode for the purpose of this post (I’ll explain configuring SharePoint integrated mode and Kerberos authentication in a future post). Configuring Kerberos avoids the authentication failures due to double-hop issues. These double-hop errors occur when a users windows domain credentials can’t be passed to another server to complete the user’s request. In the case of my customers, users were executing Reporting Services reports that were configured to query Analysis Services cubes on a separate machine using Windows Integrated security. The double-hop issue occurs as NTLM credentials are valid for only one network hop, subsequent hops result in anonymous authentication. The client attempts to connect to the report server by making a request from a browser (or some other application), and the connection process begins with authentication. With NTLM authentication, client credentials are presented to Computer 2. However Computer 2 can’t use the same credentials to access Computer 3 (so we get the Anonymous login error). To access Computer 3 it is necessary to configure the connection string with stored credentials, which is what a number of customers I have worked with have done to workaround the double-hop authentication error. However, to get the benefits of Windows Integrated security, a better solution is to enable Kerberos authentication. Again, the connection process begins with authentication. With Kerberos authentication, the client and the server must demonstrate to one another that they are genuine, at which point authentication is successful and a secure client/server session is established. In the illustration above, the tiers represent the following: Client tier (computer 1): The client computer from which an application makes a request. Middle tier (computer 2): The Web server or farm where the client’s request is directed. Both the SharePoint and Reporting Services server(s) comprise the middle tier (but we’re only concentrating on native deployments just now). Back end tier (computer 3): The Database/Analysis Services server/Cluster where the requested data is stored. In order to enable Kerberos authentication for Reporting Services it’s necessary to configure the relevant SPNs, configure trust for delegation for server accounts, configure Kerberos with full delegation and configure the authentication types for Reporting Services. Service Principle Names (SPNs) are unique identifiers for services and identify the account’s type of service. If an SPN is not configured for a service, a client account will be unable to authenticate to the servers using Kerberos. You need to be a domain administrator to add an SPN, which can be added using the SetSPN utility. For Reporting Services in native mode, the following SPNs need to be registered --SQL Server Service SETSPN -S mssqlsvc/servername:1433 Domain\SQL For named instances, or if the default instance is running under a different port, then the specific port number should be used. --Reporting Services Service SETSPN -S http/servername Domain\SSRS SETSPN -S http/servername.domain.com Domain\SSRS The SPN should be set for the NETBIOS name of the server and the FQDN. If you access the reports using a host header or DNS alias, then that should also be registered SETSPN -S http/www.reports.com Domain\SSRS --Analysis Services Service SETSPN -S msolapsvc.3/servername Domain\SSAS Next, you need to configure trust for delegation, which refers to enabling a computer to impersonate an authenticated user to services on another computer: Location Description Client 1. The requesting application must support the Kerberos authentication protocol. 2. The user account making the request must be configured on the domain controller. Confirm that the following option is not selected: Account is sensitive and cannot be delegated. Servers 1. The service accounts must be trusted for delegation on the domain controller. 2. The service accounts must have SPNs registered on the domain controller. If the service account is a domain user account, the domain administrator must register the SPNs. In Active Directory Users and Computers, verify that the domain user accounts used to access reports have been configured for delegation (the ‘Account is sensitive and cannot be delegated’ option should not be selected): We then need to configure the Reporting Services service account and computer to use Kerberos with full delegation:   We also need to do the same for the SQL Server or Analysis Services service accounts and computers (depending on what type of data source you are connecting to in your reports). Finally, and this is the part that sometimes gets over-looked, we need to configure the authentication type correctly for reporting services to use Kerberos authentication. This is configured in the Authentication section of the RSReportServer.config file on the report server. <Authentication> <AuthenticationTypes>           <RSWindowsNegotiate/> </AuthenticationTypes> <EnableAuthPersistence>true</EnableAuthPersistence> </Authentication> This will enable Kerberos authentication for Internet Explorer. For other browsers, see the link below. The report server instance must be restarted for these changes to take effect. Once these changes have been made, all that’s left to do is test to make sure Kerberos authentication is working properly by running a report from report manager that is configured to use Windows Integrated authentication (either connecting to Analysis Services or SQL Server back-end).

  • Copying Columns from Grid to Clipboard in SQL Developer

    - by thatjeffsmith
    There are several ways to get data from a query or a table|view to the clipboard. You know the tried and true, copy and paste. But what if you only want one or more columns, not every column? There are several ways to do this, let’s see if we can’t identify all of them. Write your query to only include the data you want Obvious? Yes. Needed to be said? Definitely. The best tuning tip is to only ask for the data you need, only when you absolutely need it. But let’s look at a few more practical ways to do this. Hide the unwanted columns Mouse right click on an column header. In the context menu, select ‘Columns.’ Hide the columns you don’t want. Copy and paste. WYSIWYG Grids, Hide Columns and Filter Rows Mouse select the columns Obvious, but a bit painful. For a very large dataset, you’ll be holding down the Shift and PageDown buttons – but it works. Remember to use Ctrl+Shift+C to get the column headers with the data. Use the Export Wizard This used to be called ‘Unload’ – agreed, not a great name. So, we changed it. In a grid, right mouse click on the data, and on the context menu, select ‘Export…’ Select your format – I suggest ‘delimited’ or ‘fixed’ for copying data to the clipboard. You can export to the clipboard, yes you can! Click ‘Next.’ Click in the Columns dialog, and choose the columns you want copied. Trim the columns you don't want copied Click ‘Finish.’ Alt or Ctrl tab to your window or application of choice. And Paste! "FIRST_NAME" "LAST_NAME" "Donald" "OConnell" "Douglas" "Grant" "Jennifer" "Whalen" "Pat" "Fay" "Susan" "Mavris" "William" "Gietz" "Alexander" "Hunold" "Bruce" "Ernst" "David" "Austin" "Valli" "Pataballa" "Diana" "Lorentz" "Daniel" "Faviet" "John" "Chen" "Ismael" "Sciarra" "Jose Manuel" "Urman" "Luis" "Popp" "Alexander" "Khoo" "Shelli" "Baida" "Sigal" "Tobias" "Guy" "Himuro" "Karen" "Colmenares" "Matthew" "Weiss" "Adam" "Fripp" "Payam" "Kaufling" "Shanta" "Vollman" "Kevin" "Mourgos" "Julia" "Nayer" "Irene" "Mikkilineni" ... There’s probably at least 2 or 3 more ways, but… But, try these and let me know how we can improve things. I’ve already gotten a request to be able to include the SQL text used to populate the dataset on the the copy to clipboard, and it’s now on our to-do list
