The following documents are piecemeal and sporadic:

http://confluence.atlassian.com/display/DOC/External+Database
http://confluence.atlassian.com/display/DOC/Database+Configuration
http://confluence.atlassian.com/display/DOC/Database+Setup+Guides
http://confluence.atlassian.com/display/DOC/Migrate+to+Another+Database

These four resources should be combined and streamlined. Remember to consider that installation and upgrade guides refer to this documentation.

Reviews:

• I've asked David Mason to review the two Oracle docs. Friday 26 April: He's happy with the docs. Suggested I combine the notes about needing to be a DBA.
• Held a meeting with Renan and David M on Wednesday 1 May for final review of the entire set. Just a few changes to make, now also applied.
