SQL 2005 includes a very easy to use method to setup and remove mirroring using SQL Server Management Studio however, when you are dealing with 30+ databases spread across multiple instances, it becomes tedious to use GUI to setup and remove mirroring.
I have included two scripts that may assist you in performing the task using T-SQL as follows:
1. Setup mirroring: This script generates nine (9) distinct steps using information you provide for a single database - these steps can then be used to save scripts to quickly setup mirroring logic for each database. I have tried to include detailed comments on what each step does and section on what information you need to have available to generate the final script (see script for further details). Note: I have not included piece for Witness.
2. Remove mirroring: This script generates manual failover script for all databases per server \ instance that are mirrored. Note: This does not actually do failover but just generates the script that you can then use to do failover.
Hope this helps you in your day-to-day job function or during disaster recovery exercise. Would love to hear of suggestions to improve these.
