Who are you? Development DBA or Production DBA.


Development Oracle DBAs:

Generally speaking, Oracle Development DBAs are concerned with developing applications from a database perspective. Here are some of their tasks:
  • ·         Know the source code very well, and the database structure
  • ·         Look mainly after one or a set of applications
  • ·         Involved in SQL tuning, and re-writing of code
  • ·         Development of new functionality
  • ·         Liaise with developers regularly in development issues


Production Oracle DBAs

On the whole, the Oracle Production DBA is all about maintaining a reliable, secure and performant database. Here are some common tasks:
  • ·         Patching
  • ·         Storage and capacity planning
  • ·         Backup and recovery
  • ·         Rollout of new releases
  • ·         Performance tuning of instance as a whole
  • ·         Troubleshooting expert

It’s also essential to bear in mind that there will certainly be overlap in any job you go to; just because you don’t work on production doesn’t mean you shouldn’t know how to patch or backup and recover a database. These are just an idea of the main functions of the different types of roles and what you can expect to spend most of your time doing.

It is very commong for you to be both the Development and Production DBA. I would say that at much larger organisations where there are many Oracle DBAs you are more likely to get the distinction between Development and Production DBAs. In smaller companies, you are more likely to be working both as the Development and Production DBA.

Enjoy:-)
