• SQL SERVER – Why Do We Need Master Data Management – Importance and Significance of Master Data Management (MDM)

  - by pinaldave

  Let me paint a picture of everyday life for you.  Let’s say you and your wife both have address books for your groups of friends.  There is definitely overlap between them, so that you both have the addresses for your mutual friends, and there are addresses that only you know, and some only she knows.  They also might be organized differently.  You might list your friend under “J” for “Joe” or even under “W” for “Work,” while she might list him under “S” for “Joe Smith” or under your name because he is your friend.  If you happened to trade, neither of you would be able to find anything! This is where data management would be very important.  If you were to consolidate into one address book, you would have to set rules about how to organize the book, and both of you would have to follow them.  You would also make sure that poor Joe doesn’t get entered twice under “J” and under “S.” This might be a familiar situation to you, whether you are thinking about address books, record collections, books, or even shopping lists.  Wherever there is a lot of data to consolidate, you are going to run into problems unless everyone is following the same rules. I’m sure that my readers can figure out where I am going with this.  What is SQL Server but a computerized way to organize data?  And Microsoft is making it easier and easier to get all your “addresses” into one place.  In the  2008 version of SQL they introduced a new tool called Master Data Services (MDS) for Master Data Management, and they have improved it for the new 2012 version. MDM was hailed as a major improvement for business intelligence.  You might not think that an organizational system is terribly exciting, but think about the kind of “address books” a company might have.  Many companies have lots of important information, like addresses, credit card numbers, purchase history, and so much more.  To organize all this efficiently so that customers are well cared for and properly billed (only once, not never or multiple times!) is a major part of business intelligence. MDM comes into play because it will comb through these mountains of data and make sure that all the information is consistent, accurate, and all placed in one database so that employees don’t have to search high and low and waste their time. MDM also has operational MDM functions.  This is not a redundancy.  Operational MDM means that when one employee updates one bit of information in the database, for example – updating a new address for a customer, operational MDM ensures that this address is updated throughout the system so that all departments will have the correct information. Another cool thing about MDM is that it features Master Data Services Configuration Manager, which is exactly what it sounds like.  It has a built-in “helper” that lets you set up your database quickly, easily, and with the correct configurations.  While talking about cool features, I can’t skip over the add-in for Excel.  This allows you to link certain data to Excel files for easier sharing and uploading. In summary, I want to emphasize that the scariest part of the database is slowly disappearing.  Everyone knows that a database – one consolidated area for all your data – is a good idea, but the idea of setting one up is daunting.  But SQL Server is making data management easier and easier with features like Master Data Services (MDS).

• Using JPA 2.0 with WebLogic Server 10.3.4 and Eclipse

  - by greg.stachnick

  Beginning in Oracle Enterprise Pack for Eclipse (OEPE) 11.1.1.6.1, we introduced a new feature for WebLogic Server configuration called Server Extensions. Similar in concept to project facets, Server Extensions allow us to install additional technologies, libraries, configurations, etc into an existing server runtime. WebLogic Server 10.3.4 introduces new support for Java Persistence 2.0, the new JEE 6 standard entity access. In order to start developing JPA 2.0 applications with WebLogic Server 10.3.4, a SmartUpdate patch must be applied to add and configure the EclipseLink libraries. More information on the manual EclipseLink installation and configuration can be found here. OEPE provides a Server Extension for JPA 2.0, making the addition and configuration of JPA 2.0 and EclipseLink much easier. When defining a new WebLogic Server 10.3.4 configuration, simply click the Install link for Java Persistence 2.0 and OEPE will take care of the WebLogic Server enablement for JPA 2.0.

• .NET app - Should we use SQL Server and duplicate some reference data from an external Oracle DB? Or use Oracle and have a DB link?

  - by Daventry

  We're looking to migrate some existing Excel/Access processes into a new system which will provide the users with a Silverlight frontend to run and view the reports instead of using MS Access. The initial idea was to have SQL Server 2008 as RDBMS. The problem is that we've got some static data such as country codes, counterparties, etc which live in an existing Oracle DB. Since we do not want to duplicate that data (if possible), we were thinking of having a DB link between SQL Server and Oracle, but our firm does not allow that. So the options are either duplicate the data or use Oracle as RDBMS - surprise, the firm does allow DB links between Oracle databases. The initial idea was also to use WCF RIA Services, Entity Framework, etc which we're not sure they play well with Oracle, that's why it was decided to go with SQL Server in the first place. Would you advise to go for Oracle so that we can just link the static data? Or use SQL Server 2008 and replicate it because it's "safer" to stay within the Microsoft land? To use or not to use Entity Framework and WCF RIA Services at all? Regards. UPDATE: Thanks everyone for your answers. Nothing is set in stone yet. We'll try to import the data instead of linking, as if the other DB goes down, our system can still carry on. We're likely to use SQL Server just because most developers are more experienced with it. Even if we used RIA Services, we can swap out the Data Access Layer and use other frameworks such those mentioned below.

• Disqus thread migration. Gotchas?

  - by sramsay

  I've been migrating a site to a new domain. The site itself is pretty straightforward (it uses Jekyll), and everything has gone fine -- except migration of Disqus threads. I've had partial success -- some of the threads have migrated successfully, but not all. I've tried the domain migration wizard (which caught a few), the URL mapper (which caught a few), and the 301 redirect crawler (which caught a few). But the remaining threads just won't move, no matter which method I use. So, I suppose I suppose I'm asking if there are any "gotchas" I should know about with this. When you execute any of these migration tools, it says it will "take awhile." Does that mean hours? Days? I can't tell if it's working, and there's no logging or error reporting that I can see.

• Le Ministère des Affaires Étrangères allemand stoppe sa migration vers Linux et revient à Windows XP, en attendant Windows 7

  Le Ministère des Affaires Étrangères allemand stoppe sa migration vers Linux Et revient à Windows XP, en attendant Windows 7 Le Ministère des Affaires Étrangères allemand a annoncé dans une lettre ouverte qu'il abandonnait la migration de son parc informatique vers Linux. L'institution avait commencé la migration de ses serveurs en 2001 et celle de ses postes en 2005. Un mouvement accompagné par la promotion de logiciels open source comme le navigateur Firefox, la suite bureautique OpenOffice ou le gestionnaire de messagerir Thunderbird. En 2007, le ministère avait publié un rapport d'évaluation qui montrait que les coûts par poste de travail étaient moins élevés qu...

• sql perfomance on new server

  - by Rapunzo

  My database is running on a pc (AMD Phenom x6, intel ssd disk, 8GB DDR3 RAM and windows 7 OS + sql server 2008 R2 sp3 ) and it started working hard, timeout problems and up to 30 seconds long queries after 200 mb of database And I also have an old server pc (IBM x-series 266: 72*3 15k rpm scsi discs with raid5, 4 gb ram and windows server 2003 + sql server 2008 R2 sp3 ) and same query start to give results in 100 seconds.. I tried query analyser tool for tuning my indexed. but not so much improvements. its a big dissapointment for me. because I thought even its an old server pc it should be more powerfull with 15k rpm discs with raid5. what should I do. do I need $10.000 new server to get a good performance for my sql server? cant I use that IBM server? Extra information: there is 50 sql users and its an ERP program.

• Migrating JBoss installation and install it on a PHP server

  - by David Martinez

  I'm configuring a new dedicated server that is going to run 3 sites, 2 of then are migrating from a old server. Each site have it's own domain and dedicated ip. 2 of this sites are already up and running on php (one of then use cakePHP), the third site is a migration from an old server and it runs on JBoss. 1) Is it possible to have both Jboss and php running on the same Apache instance, or would I have to install a new one? 2) Can I just move the old JBoss server directory to the new server and start the server with the shell script? From what I red here JBoss is distributed as a zip/tgz file with the server structure, so moving it from the old server to the new one should be the same. I want to do this because the old server is already configured, and it have 2 JBoss instances. I didn't develop this site and I don't have experience with JBoss. I have some documentation of the site, but it is not much, mostly server structure and the technology they used. The new server runs on CentOS with CPanel, I have full root access to the server. This question is similar to this one How can I run JBoss Application Server and Apache on the same server? but there he didn't have a dedicated IP for each domain.

• SQL SERVER – The Difference between Dual Core vs. Core 2 Duo

  - by pinaldave

  I have decided that I would not write on this subject until I have received a total of 25 questions on this subject. Here are a few questions from the list: Questions: What is the difference between Dual Core and Core 2 Duo? Which one is recommended for SQL Server: Core 2 Duo or Dual Core? Can I upgrade my Dual Core to Core 2 Duo? If Dual Core has 2 CPUs, how many CPUs does Core 2 Duo have? Is it true that Core 2 Duo and Dual Core meant the same thing? Well, let us see the answer. Optimistically, I would be directing everybody to this blog post if I receive a question of the same kind sometime in the future. To verify the information that I provide, visit Intel’s site. For additional information regarding the subject, visit Wikipedia. My Answer: Any computer that has two CPUs or two “cores“ is known as Dual Core. Core Duo is a brand name of Intel for Dual Core. Core 2 Duo is simply a higher version of Core Duo. (e.g. for Pentium brand, it`s like Pentium I, Pentium II, etc.) The computer I am using now has Core 2 Duo. Intel has launched a new brand, which they call i3, i5, and i7.  Here, the numbers are not related to the number of cores; rather, they show the range of the CPU. I3 is of low range and i7 is of high range. Feel free to add more details by adding valuable comments here. And if you still want to ask why I created this blog post, well, I mentioned that I was waiting for 25 questions threshold to hit, before I write about this subject which I didn`t really plan to write about.

• Sharing business logic between server-side and client-side of web application?

  - by thoughtpunch

  Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

• Google privacy concerns: trustworthy alternatives for migration?

  - by Markos Fragkakis

  I have come to realize the tremendous amount of information Google has on its users. I am a typical Google user, using Gmail, Google Reader. This means that right now Google now has the following information at its disposal: Who my friends are (Gmail) What we talk about (Gmail, Google Talk) What news sources I follow (Google Reader) How frequently I check them and which ones I consider important enough to share (Google Reader) A lot of other stuff What I search about and when (if I search when logged in) (Web search) I have no reason to believe that this information is used for reasons other than adjusting what ads I am displayed when I visit a site with Google Ads. However, I have realised that I am in no position to be certain that this is absolutely true, or that it always will be. On the other hand, I don't want to reach the uber-privacy-maniac state of maintaining my own email server and installing a desktop RSS reader in all my machines. So, I am asking for your opinions: What services constitute a good set of alternatives to the Google services, promising better privacy? Pros: Privacy Free Powerful Usable

• Migrating mysql 4 to mysql 5

  - by Lennart Regebro

  This seems to me to be a common use case, so I'm surprised so little information is about it, so sorry if it's a duplicate, but I have searched. :) I'm migrating a clients website from one CMS to another, and of moving to newer faster machines all at the same time. As a part of this I'm moving a MySQL database from the old server to the new ones. The problem is that the old server runs MySQL 4 and the new MySQL 5. So when i do a mysqldump at the old site and then try to run it on the new site I get syntax errors. ERROR 1064 (42000) at line 178: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'BTREE (`id`), KEY `f_ChangedOnWeb` (`f_ChangedOnWeb`), KEY `f_AddressUpdate`' at line 56 I also tried to use an even older syntax by dumping with --compatible mysql323, but that just resulted in ERROR 1062 (23000) at line 2283: Duplicate entry '??????????' for key 2`... It seems to me this must be a reasonably common use case, yet I can't find any sort of help on this. Possibly all my Google searches just drown in irrelevant answers. Most seem to agree that mysqldump is the right answer, but noone mentions that you can get syntax errors...

• How do I migrate Exchange 2007 to new hardware?

  - by Graeme Donaldson

  As per my previous question, I have an Exchange 2007 box which is also a DC. Since I can't demote it while Exchange is installed, I want to move Exchange to a different server. Does anyone have any articles, tips or experiences to share on this? The last time I did this it was with Exchange 2003 and even that is a little rusty in my head. The setup is a single Exchange 2007 Hub/Edge/Mailbox/CAS server. Its currently on Windows Server 2008, I can migrate it to the same OS, or I can go to 2008 R2, I'm not really picky on that. We're running OWA/ActiveSync/POP3(S)/IMAP(S) for client access. I already have another fully functional DC/GC/DNS box in the same site and clients in the site are already using that for DNS. It's also the preferred site bridgehead for AD replication. Update: After reading Evan's answer I realised that my original question wasn't worded correctly. I'm not looking to do a swing migration, I actually need to move Exchange completely over to a new box. I have done swing migrations in the past, i.e. moving over to a temporary box and back to the original hardware afterwards, and I'm not really sure why I used that term in the original question since it's not what I intended. Any tips?

• Connection to mysql server in SYN_SENT

  - by Sunil

  We are facing a strange problem from last few days between our application server and database server(Mysql): connection to database server from application server hangs in SYN_SENT state and after that we are not able to make any connection to database server on mysql port(3306). When we checked the netstat output on database server its in SYN_RECV state. What I can figure out is mysql server is receiving the SYN request and responding also and its not reaching to the client hence SYN_RECV at server side and SYN_SENT at client side. I think SYN_SENT state should go after some time and because of this other db connection attempts to same server should not hang. Does anybody have any idea how can we resolve this issue?

• How to migrate Fedora DS (389 DS) to a new machine?

  - by zengr

  Hello, I am trying to migrate a Fedora DS (1.2.2) to a new server (1.2.7.5). The process has been painful to say the least. The old server (1.2.2) was also an upgrade from an old fedora DS setup, so it does not contain migrate-ds-admin.pl. I found this question, but the URL does not open. I am aware that I need to use migrate-ds-admin.pl, but I am clueless. How do I use it? I assume this works like this: 1. Copy migrate-ds-admin.pl from server which has 1.2.7 to 1.2.2 2. Run migrate-ds-admin.pl to export the schema+ldif from 1.2.2 3. Import the schema+ldif to 1.2.7 using migrate-ds-admin.pl. If the above is true, then what parameters are need for export and import? Note: ./ldif2db -n NetscapeRoot -i /root/NetscapeRoot.ldif ./ldif2db -n userRoot -i /root/userRoot.ldif The above two commands work like a charm, but since the schema (custom schema) is not migrated, I see alot of errors during import.

• How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment [closed]

  - by lmttag

  Possible Duplicate: How to Deploy an ASP.NET Web API- and Browser-based Application to a Production Environment We have an ASP.NET Web API server that serves up a SQL Server data driven website. The API uses JSON to transfer data from SQL Server to the front end. We need to move it to an internal production environment (nothing will be exposed on the public Internet) and we’re having problems - or just not understanding what needs to be done. There are two domains: The corporate domain - where all users login normally. The process domain - contains the database the Web API needs to access. The IT staff wants to put a DMZ between the two domains to house the IIS app and shield the users on the corporate domain from having access into the process domain directly. The ideal configuration is: corp domain (end users) <–> firewall (open port 80) <–> DMZ (web server running IIS) <–> firewall (open port 80 or 1433????) <–> process domain (IIS for Web API and SQL Server) We don’t really understand how to deploy our browser/Web API application in this scenario. Do we need to break up our application so that all the client code is on the IIS server in the DMZ, while the Web API gets installed on the server in the process domain? Does the entire app (client code and Web API) stay together on the IIS server in the DMZ, which then somehow accesses the SQL Server instance to get data? From the IIS server and app in the DMZ, would you simply access the Web API on the server in the process domain by going to http://server/appname/api/getitmes? In the second firewall between the DMZ and the process domain, would you have to open port 1433 or just port 80 since the Web API is a HTTP endpoint? Or, is there some better way of deployment (i.e., how ASP.NET Web API single page applications written all in HTML5 and JavaScript supposed to be deployed to production environments?)? NB: The servers are Win2k8 R2, SQL Server 2k8 R2, and IIS 7.5.

• How to push to github from a server account with multiple users?

  - by kirdie

  We have a web server which contains a web application stored as a github project. Now all of us can push from our local machines to github and then pull on the server but sometimes we want to make small changes and immediately see the effect so it would be great to be able to push at the server too. Now I created an ssh key for the server but I don't want to add the servers ssh key to my github account because then all github actions done from the server are counted to my account. Is it possible to add the ssh key to the github web application project without creating a new user for the server and what is the best practice for this situation? I also don't want to copy my private key to the server obviously.

• LAMP Server without single failure point + Global Server Load Balancing?

  - by José Nobile

  I want implement a LAMP Server (Linux Apache MySQL PHP) without a single failure point and with Global Server Load Balancing. I have a server in Cali, Colombia, and other server will be installed in Melbourne, Australia, user in America can use the Cali Server and in Europe, Asia, Africa or Oceania use the Melbourne Server. If any server fail (or load is excessively high), a server must answer all request. Data in MYSQL must be in sync, php files, any configuration in both server must be in sync. I read about of Google DNS Server 8.8.8.8 and 8.8.4.4 and ANY Cast, also about MySQL semisynchronous replication and MySQL Cluster, but what about other things, as crontabs, and the configurations in server? The solution can't depend of APNIC or BGP, only open source software running in Linux.

• Entourage to Outlook Migration questions

  - by George Bluff

  I am currently migrating a users information from a pop email account to my exchange server. I have already migrated them over to my hosted exchange, and their email is following properly. Now, the user is moving from Entourage on a Mac (10.7) to Outlook 2010 on a PC (Windows 7). I was wondering what the easiest way was to migrate him since there is no .pst files. I have been able to get his email over by dragging the inbox from Entourage to the desktop, then converting the files to .eml using IMAPSize, importing them to Outlook Express (which will only work on Windows XP), then exporting to a pst, then importing in the new account. Takes awhile with large emails, but it works. The issue I am now having is for calendar items. I exported the calendar and got a folder with all the .ics files, but Outlook 2010 doesn't seem to have an easy way to import all of them. Any thoughts?

• How to record audio in Windows Server 2008 Web SP2?

  - by Aurelio De Rosa

  I face into this problem and before ask here I've searched and read a lot of question but no-one seems to fit to my problem. I have a server running Windows Server 2008 Web with the SP2 and a headset attached to it using audio jack. The server has audio driver since I can listen audio. This OS does not came with the built-in audio record tool (the one I have in Windows 7). I can access physically and remotely (using RDC) to this server with administration permission. My local pc has Windows 7 if it can help. All I want to do is to know if it's possible and how to record audio form the microphone (of the server) and store that file in the server from remote connection. I tried to install several software on the server but everyone fails with a different issues (missing DLL which if I put in the system the error doesn't go away).

• Upgrading Team Foundation Server 2008 to 2010

  - by Martin Hinshelwood

  I am sure you will have seen my posts on upgrading our internal Team Foundation Server from TFS2008 to TFS2010 Beta 2, RC and RTM, but what about a fresh upgrade of TFS2008 to TFS2010 using the RTM version of TFS. One of our clients is taking the plunge with TFS2010, so I have the job of doing the upgrade. It is sometimes very useful to have a team member that starts work when most of the Sydney workers are heading home as I can do the upgrade without impacting them. The down side is that if you have any blockers then you can be pretty sure that everyone that can deal with your problem is asleep I am starting with an existing blank installation of TFS 2010, but Adam Cogan let slip that he was the one that did the install so I thought it prudent to make sure that it was OK. Verifying Team Foundation Server 2010 We need to check that TFS 2010 has been installed correctly. First, check the Admin console and have a root about for any errors. Figure: Even the SQL Setup looks good. I don’t know how Adam did it! Backing up the Team Foundation Server 2008 Databases As we are moving from one server to another (recommended method) we will be taking a backup of our TFS2008 databases and resorting them to the SQL Server for the new TFS2010 Server. Do not just detach and reattach. This will cause problems with the version of the database. If you are running a test migration you just need to create a backup of the TFS 2008 databases, but if you are doing the live migration then you should stop IIS on the TFS 2008 server before you backup the databases. This will stop any inadvertent check-ins or changes to TFS 2008. Figure: Stop IIS before you take a backup to prevent any TFS 2008 changes being written to the database. It is good to leave a little time between taking the TFS 2008 server offline and commencing the upgrade as there is always one developer who has not finished and starts screaming. This time it was John Liu that needed 10 more minutes to make his changes and check-in, so I always give it 30 minutes and see if anyone screams. John Liu [SSW] said:   are you doing something to TFS :-O MrHinsh [SSW UK][VS ALM MVP] said:   I have stopped TFS 2008 as per my emails John Liu [SSW] said:   haven't finish check in @_@   can we have it for 10mins? :) MrHinsh [SSW UK][VS ALM MVP] said:   TFS 2008 has been started John Liu [SSW] said:   I love you! -IM conversation at TFS Upgrade +25 minutes After John confirmed that he had everything done I turned IIS off again and made a cup of tea. There were no more screams so the upgrade can continue. Figure: Backup all of the databases for TFS and include the Reporting Services, just in case.   Figure: Check that all the backups have been taken Once you have your backups, you need to copy them to your new TFS2010 server and restore them. This is a good way to proceed as if we have any problems, or just plain run out of time, then you just turn the TFS 2008 server back on and all you have lost is one upgrade day, and not 10 developer days. As per the rules, you should record the number of files and the total number of areas and iterations before the upgrade so you have something to compare to: TFS2008 File count: Type Count 1 1845 2 15770 Areas & Iterations: 139 You can use this to verify that the upgrade was successful. it should however be noted that the numbers in TFS 2010 will be bigger. This is due to some of the sorting out that TFS does during the upgrade process. Restore Team Foundation Server 2008 Databases Restoring the databases is much more time consuming than just attaching them as you need to do them one at a time. But you may be taking a backup of an operational database and need to restore all your databases to a particular point in time instead of to the latest. I am doing latest unless I encounter any problems. Figure: Restore each of the databases to either a latest or specific point in time.     Figure: Restore all of the required databases Now that all of your databases are restored you now need to upgrade them to Team Foundation Server 2010. Upgrade Team Foundation Server 2008 Databases This is probably the easiest part of the process. You need to call a fire and forget command that will go off to the database specified, find the TFS 2008 databases and upgrade them to 2010. During this process all of the 6 main TFS 2008 databases are merged into the TfsVersionControl database, upgraded and then the database is renamed to TFS_[CollectionName]. The rename is only the database and not the physical files, so it is worth going back and renaming the physical file as well. This keeps everything neat and tidy. If you plan to keep the old TFS 2008 server around, for example if you are doing a test migration first, then you will need to change the TFS GUID. This GUID is unique to each TFS instance and is preserved when you upgrade. This GUID is used by the clients and they can get a little confused if there are two servers with the same one. To kick of the upgrade you need to open a command prompt and change the path to “C:\Program Files\Microsoft Team Foundation Server 2010\Tools” and run the “import” command in  “tfsconfig”. TfsConfig import /sqlinstance:<Previous TFS Data Tier>                  /collectionName:<Collection Name>                  /confirmed Imports a TFS 2005 or 2008 data tier as a new project collection. Important: This command should only be executed after adequate backups have been performed. After you import, you will need to configure portal and reporting settings via the administration console. EXAMPLES -------- TfsConfig import /sqlinstance:tfs2008sql /collectionName:imported /confirmed TfsConfig import /sqlinstance:tfs2008sql\Instance /collectionName:imported /confirmed OPTIONS: -------- sqlinstance         The sql instance of the TFS 2005 or 2008 data tier. The TFS databases at that location will be modified directly and will no longer be usable as previous version databases.  Ensure you have back-ups. collectionName      The name of the new Team Project Collection. confirmed           Confirm that you have backed-up databases before importing. This command will automatically look for the TfsIntegration database and verify that all the other required databases exist. In this case it took around 5 minutes to complete the upgrade as the total database size was under 700MB. This was unlike the upgrade of SSW’s production database with over 17GB of data which took a few hours. At the end of the process you should get no errors and no warnings. The Upgrade operation on the ApplicationTier feature has completed. There were 0 errors and 0 warnings. As this is a new server and not a pure upgrade there should not be a problem with the GUID. If you think at any point you will be doing this more than once, for example doing a test migration, or merging many TFS 2008 instances into a single one, then you should go back and rename the physical TfsVersionControl.mdf file to the same as the new collection. This will avoid confusion later down the line. To do this, detach the new collection from the server and rename the physical files. Then reattach and change the physical file locations to match the new name. You can follow http://www.mssqltips.com/tip.asp?tip=1122 for a more detailed explanation of how to do this. Figure: Stop the collection so TFS does not take a wobbly when we detach the database. When you try to start the new collection again you will get a conflict with project names and will require to remove the Test Upgrade collection. This is fine and it just needs detached. Figure: Detaching the test upgrade from the new Team Foundation Server 2010 so we can start the new Collection again. You will now be able to start the new upgraded collection and you are ready for testing. Do you remember the stats we took off the TFS 2008 server? TFS2008 File count: Type Count 1 1845 2 15770 Areas & Iterations: 139 Well, now we need to compare them to the TFS 2010 stats, remembering that there will probably be more files under source control. TFS2010 File count: Type Count 1 19288 Areas & Iterations: 139 Lovely, the number of iterations are the same, and the number of files is bigger. Just what we were looking for. Testing the upgraded Team Foundation Server 2010 Project Collection Can we connect to the new collection and project? Figure: We can connect to the new collection and project.   Figure: make sure you can connect to The upgraded projects and that you can see all of the files. Figure: Team Web Access is there and working. Note that for Team Web Access you now use the same port and URL as for TFS 2010. So in this case as I am running on the local box you need to use http://localhost:8080/tfs which will redirect you to http://localhost:8080/tfs/web for the web access. If you need to connect with a Visual Studio 2008 client you will need to use the full path of the new collection, http://[servername]/tfs/[collectionname] and this will work with all of your collections. With Visual Studio 2005 you will only be able to connect to the Default collection and in both VS2008 and VS2005 you will need to install the forward compatibility updates. Visual Studio Team System 2005 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 Visual Studio Team System 2008 Service Pack 1 Forward Compatibility Update for Team Foundation Server 2010 To make sure that you have everything up to date, make sure that you run SSW Diagnostics and get all green ticks. Upgrade Done! At this point you can send out a notice to everyone that the upgrade is complete and and give them the connection details. You need to remember that at this stage we have 2008 project upgraded to run under TFS 2010 but it is still running under that same process template that it was running before. You can only “enable” 2010 features in a process template you can’t upgrade. So what to do? Well, you need to create a new project and migrate things you want to keep across. Souse code is easy, you can move or Branch, but Work Items are more difficult as you can’t move them between projects. This instance is complicated more as the old project uses the Conchango/EMC Scrum for Team System template and I will need to write a script/application to get the work items across with their attachments in tact. That is my next task! Technorati Tags: TFS 2010,TFS 2008,VS ALM

• Loading the Cache from the Business Application Server

  - by ACShorten

  By default, the Web Application server will directly connect to the Database to load its cache at startup time. Customers, who implement the product installation in distributed mode, where the Web Application Server and Business Application Server are deployed separately, may wish to prevent the Web Application Server to connect to the database directly. Installation of the product in distributed mode was introduced in Oracle Utilities Application Framework V2.2. In the Advanced Web Application Server configuration, it is possible to set the Create Simple Web Application Context (WEBAPPCONTEXT) to true to force the Web Application Server to load its cache via the Business Application rather than direct loading. The value of false will retain the default behavior of allowing the Web Application Server to connect directly to the database at startup time to load the cache. The value of true will load the cache data via direct calls to the Business Application Server, which can cause a slight delay in the startup process to cater for the architecture load rather than the direct load. The impact of the settings is illustrated in the figure below:                             When setting this value to true, the following properties files should be manually removed prior to executing the product: $SPLEBASE/etc/conf/root/WEB-INF/classes/hibernate.properties $SPLEBASE/splapp/applications/root/WEB-INF/classes/hibernate.properties Note: For customers who are using a local installation, where the Web Application Server and Business Application Server are combined in the deployed server, it is recommended to set this parameter to false, the default, unless otherwise required. This facility is available for Oracle Utilities Application Framework V4.1 in Group Fix 3 (via Patch 11900153) and Patch 13538242 available from My Oracle Support.
