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.

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…

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.
