Kevin Kempf's Blog


An Oracle R12.2 DBA in South Carolina, USA.

This blog will likely focus mainly on Oracle, with a few diversions as I see fit.   I would describe myself as a healthy skeptic and rather pragmatic in regard to Oracle products.

Interestingly, it can also serve as a nice place to send friends and relatives when they really want to know what I do at work. (And why I’m no expert at Windows problems)

My Oracle landscape looks like this, for a total of 8 instances on 6 nodes:

  • Oracle Apps 12.2.3 on Oracle Linux 6 (x86-64, UEK) with non-container RDBMS on Oracle Linux 6 (x86-64, UEK) sitting on VMWare,  utilizing Dataguard over WAN as disaster recovery insurance
  • Development, Regression Testing, Training, and Audit versions of the 12.2 environment
  • A handful of standalone Oracle databases (10.2 – 11.2) on Oracle Linux 6 (x86-64, UEK) running disparate applications. One of these runs on Windows 2008R2, due to 3rd party vendor constraints (all VMWare virtual machines)
  • Oracle Enterprise Manager 12c with RDBMS on Oracle Linux 6 (x86-64) with Diagnostics and Tuning packs.
  • Oracle APEX integrated into R12 as our solution to replace Discoverer since we’re not sophisticated/rich enough for OBIEE.
  • RMAN backups for everything, orchestrated out of EM 12c.

All the opinions and explanations expressed in the blog are my own, use at your own risk!

Please feel free to leave comments! I’d like to know if you agree, disagree, have had a similar issue, etc.

I look forward to hearing from you.


  1. Hi
    I’m from Mexico and you have no idea how much I laugh with your article “Resolved with Solution? “, it’s awesome how we can get the same comments from different topics, and I thought I couldn´t be more surprise that when I receive an update from the analyst: “Do you still have the issue?” after a week waiting for her update… its unbelievable.
    You´ll be surprised how things are when you´re in an On Demand @Oracle schema… I figure it out you can imagine.

    Please continue writing about technical topics and other not so much… its refreshing knowing you´re not the only one with Oracle Support issues

    Best regards

  2. Hi Kevin –

    I’m in Houston, Texas supporting an environment with Oracle 9i (in the process of decommission), 10g, 11g, and 12c (coming soon) running on Windows and Linux in VMware.

    Your article on rotating the listener logs is a total lifesaver! As our environment grows, quite frankly I am astonished at the maintenance issues that just never came up when studying how to manage your databases in school. I really appreciate your sense of humor about this stuff!

    Are you planning to attend Oracle World in a couple of weeks?

    • Glad you found my ramblings of use; I won’t be at OOW this year, though I do get out there occasionally.

  3. Hi Kevin. I hope you are well. I’m trying to find the “Oracle Portal, Forms, Reports and Discoverer 11g” installer. What I find just appears to be discoverer desktop/admin. Looking at your post for Discoverer 11g, the images show “Oracle Portal, Forms, Reports and Discoverer 11g” in the title bar and also seems to prompt for weblogic info. The Discoverer 11g I installed only prompts for the install location. I did install weblogic but skipped the RCU step because I’m working with a restored DB that was already utilized by discoverer. So I just wanted to perform the “Oracle Portal, Forms, Reports and Discoverer 11g”. I’m sorry if this seems like more of a ramble…thanks for any insights…
