How I became a Db2 for z/OS DBA... OVERNIGHT!

I imagine my story is not entirely uncommon, but it is certainly unique to me. I was a SQL Server DBA for 7 years at Southern Farm Bureau Life Insurance, when a sudden personnel change led me to becoming our company’s new Db2 for z/OS DBA, (in addition to my role as the SQL Server DBA) literally overnight.   Because I had database experience, management thought this made sense and would not be out of my realm of knowledge or comfort.  Anyone working with Db2, z/OS, knows there is so much…
