UKOUG Day 4: Oracle Cloud Control 12c for DBAs

By | Technology Survey | No Comments

Today’s first session was a round table session with Andrew Bullock, Director of Application and systems management at Oracle. The main result of this session was that the main people using Enterprise Manager Cloud Control 12c were DBA and not so much system or Weblogic Administrators. It appears also that not so many DBA have realized in production the upgrade from Grid Control 11g to Cloud Control 12c, because in case of a huge number…

UKOUG Tech13: Optimizer & SQL statements – hint or not hint that’s the question

By | Technology Survey | No Comments

It’s the final day of Tech13, less sessions but still good topics. Mainly about the Oracle’s optimizer: looking at the execution plans and a debate about hinting SQL statements. I will focus on the hint topic in this blog. Due to trip planning it’s a much shorter day, less time for attending sessions and less time for blogging. I will focus on the debate between Tony Hasler and Jonathan Lewis about how the optimizer takes…

UKOUG Day 3: PL/SQL hints by Tom Kyte & Oracle Active Data Guard

By | Technology Survey | No Comments

Today’s first session I assisted was presented by Tom Kyte. He talked about SQL topics we surely do not know. The first topic concerned the possibility of using the plsql_warning clause with the PL/SQL compiler. This feature exists since version 10.1 but is not widely used. The different values you can define for the plsql_warning with a classical alter session command are: Severe: code might cause unexpected errors or wrong results Performance: code might cause…

UKOUG Tech13: Day 2 – PL/SQL performance, Pluggable database API and so on

By | Technology Survey | No Comments

Tech13 – Day 2: 11 different streams with 3 dedicated to the databases. Many interesting topics and it’s sometimes hard to choose to which session attend. I tried to keep an eye on sessions about performances. I was interested on more than 6 sessions for that day but I can’t speak of all. PL/SQL performance Timothy Hall, blogger from oracle-base.com was speaking about improving the performance of PL/SQL calls from SQL. It’s not always easy…

Oracle Open World 2013: Final day – Database as a service and replication fundamentals

By | Technology Survey | No Comments

My final day at Oracle OpenWorld 2013, less sessions and less people but still a big day after almost one week in San Francisco. In this blog I’ll focus on the private cloud with databases as service and the fundamentals about replication. To conclude on Oracle OpenWorld, I would say that there are three big news – more on these at the end of this posting. On Thursday, there are less people in the sessions…

Let’s talk about the 4th day in San Francisco at Oracle OpenWorld 2013. Many conferences, hands on labs, keynotes and so on. Some sessions are in the biggest room with many people. Today, we will focus on the new In-Memory option. I have already posted about that feature, but today, I went to an In-Memory session to get a little more details on it – many pictures and less text (easier to gigest ;-). Larry…

Oracle Open World 2013: 3rd day – Hands on lab, Optimizer tips and Microsoft Cloudn

By | Technology Survey | No Comments

Today, I’ll talk about the 3rd day at Oracle OpenWorld 2013 and I’ll be shorter than yesterday, too much text. Actually, it’s difficult to have good pictures during the conferences. So what’s the program in this blog: a “hands on lab” session about Linux management, a keynote from Microsoft and few tips about the optimizer. Too much text and not enough photos, I already told that the event is impressive: And it’s just one place!…
