Database naming conventions

[Godlewski, Melissa]

List,   I'm use to using a standard D=development T=test P=production.  So for a database newly created on development it would be called something like D24X7.  Then when it was created on Production it would be called P24X7.  Or along similar lines.   I'm working with an other DBA who wants everything to start with ora.  Therefore it would be called orad24x7 and orap24x7.  I've argued the ora is rather redundant since everyone will know it's an Oracle database they are connecting to.  He is adamant it should have the ora identification so it is easily identified.  I feel it will cause more confusion having ora at the beging of every dbname.    Any thoughts for against either position?   TIA M.Godlewski
