About me

Howdy. My name's John Piwowar. In the last dozen or so years, I've worked as a database administrator (Ingres and Oracle), application server administrator, ad server administrator, and de facto Linux systems administrator. All of that variety aside, much of my work has been has been in the Oracle product space, focussed on the RDBMS, so when I don't have this blog to blather in, I just simplify the list and tell people I'm an Oracle DBA. :-) These days, my primary focus is on Oracle E-Business Suite. I'm currently working as an Oracle Apps DBA for The Pythian Group, working remotely from my home in Vancouver, BC, Canada (originally from Pittsburgh, PA, USA...Go Steelers, and um, Go Penguins, assuming there's ever NHL hockey again).

More briefly stated: Hi, I'm John. I make other peoples' software work.

Certified, or just certifiable?

OCP DBA logo
I'm an Oracle 9i OCP DBA, which I think means that I'm allowed to display the following logo:

EBiz 11i OCP
I've also passed exam 1Z0-233, which in combination with the 9i OCP DBA certification grants the Oracle 11i Applications Database Administrator OCP designation.

10g RDBMS OCP I've also upgraded my 9i OCP DBA certification to 10g. Once I get some actual 11g RDBMS work under my belt, instead of mucking around in a personal lab environment, I'll tackle the next upgrade exam.

And finally (for now, anyway), thanks to beta exam 1Z1-238, I'm also a Certified Oracle E-Business Suite R12 Applications Database Administrator.

    I found your page from the .sig on some Oracle page where you were helping someone on Mac library paths. That from a google because I'm found some code from a 10.2 app and am trying to get it to work with Snow Leopard. Sounds like a reasonable few night's work for a retired engineer.

    BUT, Why I'm posting this.

    One, I found your writing style to be clear, thorough, and at a friendly level. I think that's rare these days.

    Two, hovering over one of the links embedded I found the word 'frippery'. Hmm, is this a reference to Robert Fripp?

    Its Friday evening, and what's one to do for the evening but get cozy with Xcode 3.0 and figure out why it won't see the Carbon calls.

    Hi Jim,
    Thanks for the visit! Glad you like my writing style; I try to maintain a genuine voice. It's a blog, after all, so I might as well be me. Now, if only I were as clear and thorough in face-to-face communications. ;-) With respect to the "frippery" link, I probably meant it in the "silly trivia" sense. I've enjoyed King Crimson in the past, but a Robert Fripp reference would imply a level of fandom that I can't really claim.

    Hope you were victorious in wrestling with Snow Leopard and Xcode.

    Greetings - Is there a way to access Oracle EBS runing on VMWare Player Guest from a browser on Windows 7 hosting the VMWare Player? If so, please explain how. I need to access EBS forms UI which is not working on Linux UI. Thanks a bunch!

    Hi Shamshad,
    Thanks for the visit, and the question. I don't have direct experience with VMware Player in this configuration, but as long as you've set up your virtual network adapters to allow communication between the host and guest (NAT, bridged, and host-only should all allow this), you should be fine. You'll want to add the hostname and ip of the VMware Player guest to your Windows hosts file.
