1 I had to do an in-place upgrade on a critical production system overnight. It was an active active cluster on SQL 2005 and was upgrading to 2008. I had to read clearly the differences between clustering installation in both and had to be very sure i understood. After going through test installs we decided this was too risky and went with new hardware, new os, it was still an in place install since they required us to have the same server name. So had to extensively document the older system and rebuild the new system from scratch overnight.
2 Had two fellow dbas leave in quick succession, had to handle work of 3 dba’s. Learnt how to multi task and automate monitoring, buy and use tools…Also automated the dba daily checklist to the extent possible so that i dont have to manually check processes running, event logs, job failures and so on. Used powershell/vbscript to achieve this.
