Oracle Database 12c : EXPAND_SQL_TEXT, APPROX_COUNT_DISTINCT, Session Sequences and Temporary Undo

While I was away on the OTN APAC tour, I wasn’t really able to sink my teeth into anything, so inspired by Connor McDonald‘s session in Perth, I decided to write up a few bits and pieces in my free moments in the hotels and planes (when I had enough elbow room to type). Here […]

Pattern Matching (MATCH_RECOGNIZE) in Oracle Database 12c

I’ve spent the last couple of evenings playing with the new SQL pattern matching feature in Oracle 12c. Pattern Matching (MATCH_RECOGNIZE) in Oracle Database 12c Release 1 (12.1) I’m doing some sessions on analytic functions in some upcoming conferences and I thought I should look at this stuff. I’m not really going to include much, […]

JSON Support in Oracle Database 12c (12.1.0.2)

I spent a bit of time at OpenWorld looking at the JSON support in Oracle Database 12c. I started to write some stuff about it on the plane home and I spent the last two mornings finishing it off. You can see the results here. JSON Support in Oracle Database 12c Release 1 (12.1.0.2) Indexing JSON […]

To PDB or not to PDB : The final decision

After yesterday’s to PDB or not to PDB post, I decided the answer was “to PDB”. Here’s what I did… Installed the Oracle 12c (12.1.0.2) software. There is an installation article here, but all I had to do was a software-only installation because the OS already met all the prerequisites because of the existing 11.2.0.3 […]

To PDB or not to PDB

I’m about to start a Proof of Concept (POC) for a 12c upgrade of one of our databases. The production database in question is running on Oracle Linux inside a VMware virtual machine, so the starting point I’ve been given for the POC is a clone of the whole VM… Probably the biggest decision I’ve got to […]

EM Cloud Control 12c : The 24 Hour DBA

I think I’ve lived through all the ages of Enterprise Manager. I used the Java console version back in the days when admitting you used it got you excommunicated from the church of DBA. I lived through the difficult birth of the web-based Grid Control. I’ve been there since the start of Cloud Control. I’ll […]
