About the Blog

GrepOra is a blog between friends to learn and share about our daily experiences and challenges with Oracle technologies.

The blog started in Jan/2015 called MatheusDBA, focused in Oracle Database stuff, being written only by Matheus. In November 2015, ore authors specialized in other Oracle related technologies joined Matheus as new authors and the blog was renamed to

The common thing is that we all work with Oracle by different ways: Database, Middleware, Integration and Application. Someday we realized we’re always having conversations and frequently about Oracle stuffs. So we decided to make a “grep” in these conversations to filter those are related to Oracle and share.
And this is the origin for the name “” (or |GREP ORA).

Grepora is also our way to say “thank you” to community and return part of all learning we got through blogs and communities.

First Post


Acting as DBA since 2009, I created this blog to document and share some notes… Something like a survival kit to access when I need. I expected I can help you too…

You can find/contact me basically on email ( and Linkedin.

Hugs and may the force be with us!
