I am an Oracle DBA who has been doing the job since about 1992. I remember V5 but really started work on V6 and because involved full-time with Oracle when V7 came in.
I have been freelance for 12 years but I am now in permanent employment. I do want to work for a consultancy at some stage as I like working on site although not for 1-2 day gigs but to perform a chunk of work.
I do not profess to be an expert in any way and these blogs will probably cover areas that I did not know or had problems with and try to answer some of the questions I had.
At the moment (April 2008) Streams is my big problem and in particular keeping an archived-log downstream capture database updated with logs from the source database.
