Hi all,
Last 12’th occoured in Porto Alegre-RS/Brazil the GUORS (Grupo de Usuários de Tecnologia Oracle Rio Grande do Sul – Local Oracle Technology Users Group) annual meeting.

The event counts with the follow speeches (and my personal opinion):

1. Oracle 12c New features by  Alex Zaballa – Oracle ACE Director:
A quick view of 12c new features (again). It was a good presentation, limited, however, by the short time to explore all possibilities… Particularly, I’m full of “new features” speeches of a product realeased more than 2 years ago, but Alex fortunatey bring some (fresh) news about 12.2 and his expectations about it. Considering his experience, it was a good time.

Alex share his slides here: http://www.slideshare.net/alex_zaballa
I’d like to share my basis link about new features (as you can expect, it’s on Oracle Base): https://oracle-base.com/articles/12c/articles-12c

2. SQL Tuning e Melhores Práticas (SQL Tuning Best Practices) by Gustavo Braga – DELL
A good and atractive speech by Gustavo about his experiences with SQL Tuning. It wasn’t a “database view” oriented speech, much more thinking about the Dev way. Gustavo shared his great experience with some tools he use by working in a quality-oriented company and some of his personal practices. It was a good reflection, always pertinent to the DBA daily challanges.

3. Oracle Maximum Availability Architecture by Carlos Pimentel – DELL
Much more about 11g new features considering the evolution to 12c about OMAA. Carlos pointed the relevance of services, scan_listener and the different uses you can make to an Active Dataguard. It can sound overdid, but we know, most of the legacy systems and small to medium companies are not compliance yet to this patterns. Carlos is an experienced DBA and his experiences improve the subjects of his speech.

 4. Oracle 12c – Data Redaction by Alex Zaballa – Oracle ACE Director
Another 12c speech of Alex Zaballa, this time about Oracle Data Redaction, a “security-oriented” new feature. Alex showed (hands on) how to configure and use the feature, however also showed how to “kludge/bypass” the masking with a simple SQL if the user has access to SQL (discovered by David Litchfield and published http://www.davidlitchfield.com/Oracle_Data_Redaction_is_Broken.pdf). So, it was nice to know that the features exists, but a little bit unusable, right?
