Eddie Awad asks: Have you installed or recently upgraded to Oracle APEX Listener 2.0? Have you used SQL Developer 3.2 to manage APEX Listener settings? If you answered yes to both questions, you are in for an unwelcome surprise.

It’s the end of one year and the start of another, and thus time for the ‘best of’, ‘ten best’, and perhaps even ’12 best’ articles for the zodiacally-minded. Here are a few choice samples from Christopher Gait.

The main goal of global transaction ID is to make it easy to promote a new master and switch all slaves over to continue replication from the new master.

PostgreSQL:

David Wheeler is trusting the Sqitch, but cautioning about verifying first.

When Andrew Danstan moved the Buildfarm code from pgFoundry to GitHub, he started distributing release tarballs from there too.

Chris Travers is back from a break due to working hard on getting LedgerSMB 1.4 closer to release.

Having covered why nulls exist and how they can be created explicitly and implicitly, let’s look at how NULLs behave by looking at some specific examples with Bruce Momjian.
