    I used to work for Sequent using Oracle on NUMA-Q and now work for Oracle (ex-Siebel) so very interested to see your blog appear.

    BTW – excellent choice of blogging platform (and theme).

    Thanks, Andy. I wonder if we ever met? Maybe in Weybridge? I hope my content is worth your time. Always a pleasure to bump into Sequent alumni :-0

    Hi Kevin,

    Just wanted to let you know that I am enjoy and learning quite a bit from your blog in the short time I have been reading it. Tom Kyte mentioned one of your blogs a week or so ago. I have a lot of respect for Tom and have learned SO much from him. When Tom gives praise to someone else, and suggests a visit to their site, I feel obliged to to so. He was right once again.

    Keep up the great work,
