One of the challenges I always faced when working on an environment with database mirroring is managing the SQL Server jobs on the principal and mirror server. It was always a head-ache enabling and disabling the jobs on the SQL Server instances that host the principal and mirror databases.
Just came across this SQLCAT article that demonstrates an efficient way to automate this. http://blogs.msdn.com/sqlcat/archive/2010/04/01/using-sql-agent-job-categories-to-automate-sql-agent-job-enabling-with-database-mirroring.aspx
