A pretty good article. However things related are more of day-to-day activates that a DBA performs or has performed by automated tasks.

For going on-call I would suggest something more like some of the task I have to perform to prepare for going on-call:

- reviewing the previous weeks DBA callouts

- reviewing the previous weeks turnover minutes for:

- production support

- backups

- network

- resetting the DBA 'hotline' call forwarding to you phone

- changing your cell phone ringing/paging profiles

- daily changing of your work phone to call-forward to your cell phone during off hours

- for Blackberry users

- changing profiles

- changing mail folders forwarded

- attending daily/weekly turnover meeting

- help desk notification for automated tracking systems
