I have been working in IT since 1988, and DBA-ing all releases of Oracle since v6.0.29. sometime around 1991/2, both in a Production and Development capacity – which are really 2 very different jobs. I have worked on and administered most flavours of Unix, including AIX, Linux (RH & SUSE), Solaris, HP-UX, Tru-64, Dynix PTX, DG and Pyramid, as well as Windows server, although I have only got experience of clustering on AIX, Linux and Windows. I have extensive experience using SQL Server 6.5 onwards. I also have a pretty good understanding of IBM (DS), EMC and HP XP series SANs. I don’t know very much about SAN fabric or networks. I keep intending get around to learning more about it, but I suspect I’ll never find the time. I have done my fair share of programming too, initially in S370 Assembler on an IBM Mainframe against an IMS DB/DC hierarchical database (and subsequently DB2), as well as in a variety of other languages (including Cobol), but mainly in PL/SQL and Unix shell script.
