automating database migrationI have a dev tier and q tier of servers. Is there a way to automate it
so I can have a specific database ("mydb") copied (i assume a detach is required) from my dev tier server to a q tier server? I need whatever users to be reinstated for the db using "SA" authentication. Fun huh !! (bringmewa***@gmail.com) writes:

Development databases can include all sorts of junk that does not belong on a QA server. If you are using SQL 2005, you can use the Copy Database Wizard and use the Detach method to copy servers. There are options to set this up as a job. I believe SQL 2000 has similar stuff, but I have not looked at it. -- Erland Sommarskog, SQL Server MVP, esq***@sommarskog.se Books Online for SQL Server 2005 at http://www.microsoft.com/technet/prodtechnol/sql/2005/downloads/books.mspx Books Online for SQL Server 2000 at http://www.microsoft.com/sql/prodinfo/previousversions/books.mspx bringmewa***@gmail.com wrote:

To create a new table in dev, you write a script that uses the CREATE TABLE command, defining the table structure, constraints, indexes, etc.. This script is checked into version control along with any other scripts related to the enhancement. When ready for QA, the new table script and those related to it are then run in QA. You should never transfer an entire database from Dev to QA to Prod. "You should never transfer an entire

You have multiple development projects (Projects A, B, and C) under way, some related, most not. Each project involves tables and procs that are unrelated to the other projects. When Project A is ready to move to QA, how does it get there? Your developers don't have access to the QA environment, only the DBA's, QA staff, your Change Management staff, and a few development leads do. Project A gets to QA by checking out the required scripts from version control, and deploying them to the QA environment. If something isn't scripted and archived, it doesn't get deployed, period. Your QA environment stays clean, without all of the development artifacts. Finally, when Project A has been approved by QA, how does it get to production? NONE of the developers have access to production, only the DBA's and Change Management do. Project A gets deployed to production during a planned outage, by checking out the required scripts from version control, and deploying them to production. Your production environment stays clean, running only tested, stable code, with no risk of developers getting to data they should not have access to. Your way may work for you, but it would never fly in a large operation. |
