My listeners aren’t (listening)

So it seems that I need to learn more about exactly how listeners work and how databases work with them.
And especially how to have multiple databases talking to one listener and/or having more than on listener on one box.

I’ve been trying to install a 10g database and get it to register with the listener on the box, but it won’t do it.
I’m not sure if it is something to do with the fact the listener is only version 9 or if it is something I am doing wrong.

PostgreSQL

I did some digging and found out that Postgres is actually PostgreSQL an open source database. Much like MySQL.
I setup a spare laptop with Fedora 10 and installed it and got it running OK with only a few little hitches. Mostly from not knowing a thing about it.

Looks like it would be simple enough to use, it would just be a matter of learning the new syntax for everything.

Another Job

I happened to have a quick look at the jobs available at the Bureau of Meteorology yesterday. They have a “Systems and Database Specialist” position available starting at $80K.
Although I’m not going to apply for it, it has given me some ideas on how/where to improve my skills.
  • Database Tuning
  • mySQL
  • Linux
  • AIX (not sure how I’m going to do this)
  • Postgres (not even sure what this is !)

Almost ready for my OCP exam

I’ve been getting a very high score in my OCP practise exams lately. I feel I’m just about ready to do the real thing.
I want to do one or two more practises in ‘exam condition’ before I book the real thing though.

Theses exams make me nervous. It’s not only the fear of failing, but the fear of ‘wasting’ the $175 it costs to do the exam.
