About

I’m an Oracle Database Consultant at Enkitec (an Oracle Platinum Partner and one of the first Oracle partners to acquire its own Exadata Database Machine!)..

I made this weblog to serve as my Knowledge File…To share and keep track of all ideas, learnings, and experiences about my areas of interest on ORACLE (RAC, Performance, Security, etc, etc..) and LINUX. Well, it may not be “too complete” as I have envisioned but I’m working on it little by little I hope some of the posts would be useful to the community as well..

When I’m not busy with technology.. I do Underwater Hockey and Mountaineering
