Oracle Streams Apply Process changes in 11GR2

It is somewhat timely that we’ve been doing some Oracle Golden Gate testing which in turn made me curious to take a closer look at Oracle Streams in 11GR2 and see where all the performance is coming from. I’ve setup a simple replication for table t1 from schema src to schema dst, changed Apply Server parallelism to 1 and did a simple test with inserting 100 rows while performing a sql trace. Let’s get started.

Save MySQL by letting Oracle keep it GPL

In this article I am responding to many parts of Monty’s post (linked here) which are just plain not true, or are exaggerations. I will give my own answers to the self-interview questions Monty provides, as I feel he is using his name and popularity to spreading fear that is not warranted.

Oracle 11.2 Silent Installation on OpenSolaris

When Oracle announced Oracle 11.2 for Solaris (x86-64), I decided to try a silent installation of Oracle on OpenSolaris, even though it is not certified. I downloaded the Solaris ISO and installed it as 64-bit on one of my virtual machines without a problem, I was soon enjoying OpenSolaris. I eventually stopped admiring the good-looking interface and connected through a plain old black-and-white ssh terminal to execute the silent installation. Based on the silent installation that I had earlier executed on Linux for 11.2, I started the following…

A MySQL Community Member Opinion of Oracle Buying Sun

The bottom line: As both a community member of MySQL, and a service provider, I am not worried about Oracle buying Sun and acquiring MySQL in the process.

The seminar title is “How to Write Correct SQL and Know It: A Relational Approach to SQL”. It’s focused on writing reliable SQL. While SQL has been designed as a simple access interface to relational data, it turned out to be quite complex and requires your to follow a certain disciplines to produce truly reliable SQL code — relational discipline.

DBD::Oracle on AIX 5.1

I installed DBD::Oracle on an IBM AIX 5.1 box, and for once I have some good news. Anyone who has ever tried this will know of some of the troubles I speak of. When dealing with DBI and any DBD on a AIX box, you either must either be lucky enough to have the same compiler installed that built the version of Perl that comes with the box (I have never seen this happen); or you have to spend a great deal of time downloading and installing your own GCC and the building your own version of Perl. Fortunately, all the hard work was done for me by other members of my team. Here’s how to do it.
