My company has posted a Lead Oracle DBA position located in Phoenix, Arizona which is where I also live.

We would love to get someone who has PeopleSoft skills.
You would be joining a friendly and experienced team of Oracle and SQL Server DBAs who support a wide variety of applications. I’ve been here eight years and the (more...)
I did a quick survey of the latest PeopleSoft manuals to find a set of links to pass on to a couple of coworkers of mine that are interested in doing PeopleSoft DBA work so I thought I’d include the links in a post. This might give a new PeopleSoft DBA some highlights without having to read the entire manual set.
This page has a nice picture of how the environments connect:
I’m still studying for my Oracle 12c OCP exam and I was trying to run a simple example of using SQL*Loader Express and the first thing I did blew up and I think it is a bug. When I load a table with one or two columns it works fine, but when I load a table with 3 or 4 columns the last column is not loaded. Tell me this isn’t a special (more...)
I was trying to recreate the scenario where a 12c container database is flashed back to a SCN before the point that I recovered a pluggable database to using point in time recovery.
I got this ugly ORA-00600:
RMAN> recover pluggable database pdborcl;
Starting recover at 16-APR-14
using channel ORA_DISK_1
starting media recovery
media recovery failed
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-03002: failure of recover command at 04/16/2014 06:07:40
I got the newly available Kaplan test prep software for the Oracle 12c OCP upgrade exam.
I took the test in certification mode when I was tired at the end of the day some day last week and got 44% right – fail! I usually wait until I get all the questions right before taking the real test so I have a ways to go.
The practice test software has been useful in terms (more...)
Here is a zip of two examples I built as I’m learning about the new adaptive plans features of Oracle 12c: zip
The first example has the optimizer underestimate the number of rows and the adaptive plans feature switches the plan on the fly from nested loops to hash join.
In the second example the optimizer overestimates the number of rows and the adaptive plans feature switches the plan from merge join to nested loops.
Spent a good amount of time yesterday and today reading about auditing in Oracle 12c. Can’t say I read every word, but I think it was worth reading the three chapters in the Security manual related to auditing:
Chapter 21 Introduction to Auditing
Chapter 22 Configuring Audit Policies
Chapter 23 Administering the Audit Trail
I haven’t used these features but it seems like a major new piece of code with the Unified Audit Trail.
A RMAN restore and recovery that I completed today answered a couple of questions that remained after the recovery that was the topic of my post from June. Both today’s recovery and June’s involved a restore of a production database on another host and a recovery of that database to a particular point in time.
Question 1: How to rename redo logs?
When doing a restore and recovery to a point in time RMAN (more...)
This is the second in a series of posts about different performance tuning authors and speakers who have had a big impact on my career. My first post was on Craig Shallahamer. I am ordering these posts chronologically. Craig was the first to impact my career by improving my Oracle performance tuning knowledge. The next person was Don Burleson.
I have heard Don Burleson speak at several user group conferences and (more...)
In an earlier blog post I showed how I used coe_xfr_sql_profile.sql from the sqlt toolkit from Oracle support to force a particular sql statement to run with a more efficient plan that it had used in the past.
Today, I’m trying a slight variation. Take the problem query, run it with hints, and use coe_xfr_sql_profile.sql to apply the resulting plan to the original query. I built a quick and dirty test (more...)
