I found a broken link to an Oracle help document in one of my posts and when I went to the Oracle 12c database documentation to find the new URL to put in my post I found that Oracle had totally revamped their online manuals.
Here is a link to the new high level Oracle help site: url
I’ve only looked at it for a few minutes and can’t say whether I like it or (more...)
At Oracle OpenWorld, there was a lot of Oracle ADF material. I presented on Oracle ADF Bindings as part of the well-attended ADF track on User Group Sunday, and Oracle also gave some very interesting presentations on new and coming features in ADF. For example there is now an ADF component that you can use to visualize any network of nodes and edges.
But what struck me more was the fact that when Oracle buys (more...)
Oracle 12c came up with one nice new feature: Opatch, the tool known to all database administrators is now integrated into the database in the form of DBMS_QOPATCH package. If the database contains pluggable databases, the package must be executed from the root (CDB$ROOT) level, as user sys.
Also, a minor inconvenience is that there are no tabular results, results are returned as XML. It is a bit cumbersome to work with and I do (more...)
Continuous integration offers huge efficiency gains for companies but is continuous integration even possible when the application’s backbone is a massive relational database. How can one spin up database copies for developers, QA, integration testing, and delivery testing ? Its not like Chef or Puppet can spin up a 10TB database copy in a few minutes the way one can spin up a Linux VM.
There is a way and that way is called data virtualization (more...)
The annual two day AUSOUG conference in Perth is well underway, and so far, its been a wonderfully successful event. In particular, we Australians are notorious for not really getting into the networking thing, so conferences often have a lot of ‘awkward silences’ when sessions are not on, and we are meant to be (god forbid) *talking* to each other :-)
But this year has been different. Lots of banter, lots of discussion. Also, the (more...)
This blog post was written by Matt Rudd, Enterprise Support Team Lead at Fishbowl Solutions. Matt has participated in multiple WebCenter 11g upgrades during his time with Fishbowl, and recently developed a solution for an issue he ran into frequently while performing upgrades.
With the release of the ADF Content UI for WebCenter Content, it has become clear that the long-term road map for folder-based storage within WebCenter Content is based on enterprise libraries. The (more...)
I strive to keep the number non-technical posts on this blog to the minimum. However, there are days when a non-technical post has to be written. This is one of such days.
Oracle Corporation, concerned about legal and ethical issues, not only provides to its employees a document entitled Code of Ethics and Business Conduct, but also expects that every employee adheres with the standards that the document sets. For the purpose of (more...)
Its not immediately obvious the significance of this query…but trust me…you’ll love it :-)
SQL> select table_name, column_name from dba_tab_cols

We still have a position open on our Oracle database team here in Tempe, Arizona. Here is the link with an updated job description: url
We have a great team and would love to have a new member to join us.
OOW 2014 was the best so far for me and a whirl wind. After not having a presentation accepted since I left Oracle 10 years ago, I got not only a presentation accepted but 3 presentations accepted. Woohoo! Two of my presentations are available on youtube at
On top of that with the awesome support of the Oaktable, Delphix, Pythian and Enkitec , I was able to secure a (more...)
Saw an interesting post related to work I am doing locking in plans and finding plans that have changed: Carlos Sierra post on queries with changing performance.
Our DBA team uses versions of my sqlstat.sql script to find queries whose elapsed time change and we use a script from Carlos Sierra’s SQLT collection to force the execution plan back to an efficient plan that the optimizer choose in the past. Carlos Sierra’s new (more...)
Scrum: The Art of Doing Twice the Work in Half the Time by Jeff Sutherland
My rating: 5 of 5 stars
An inspiring book from one of the original creators of Scrum. Full of anecdotes about how Scrum saved projects and can be used outside the software industry. Its main purpose is to motivate you to get started using Scrum, but it does contain enough methodology to actually allow you to use the methodology. It (more...)
Sometimes I get excited over simple things. Today, I learned something new, something about human behaviors.
Basically, there are 4 quadrants for human behaviors.
If one does not understand the other person’s behavior, then communication can be very difficult.
To find more about human behaviors, read The DISC Model of Human Behavior – A Quick Overview.
Which quadrant are you in, versus your manager?
This is pretty simple, but I thought I would share it since it is helpful to me. I have been preparing for a large migration which involves table, index, type, function, package, and procedure changes. When I run a big migration like this I check for invalid objects before and after the migration and attempt to recompile any that are invalid. By checking before and after the migration I know which objects (more...)
The Manage Cloud Control | Agents page was always useful but for quickly identifying EM agent status. Prior to Release 4 this page had static icons indicating problems with specific agents. The page contained no hints about why the agents were in trouble, I’d highlight the broken agent’s row and then push the Unblock icon. There was 50-50 chance that the agent was actually blocked but, as often as not, Resecuring the agent would fix the issue. Haphazard? (more...)

Your applications contain 20-30% dead code that is never executed. Not just commented-out code that programmers have left in “just in case”, but routines never called, branches never executed and screens never displayed.
The cost of software maintenance depends on the size of the code base, but systems with dead code are more expensive to maintain. This is because every time a developer comes across a dead piece of code, he becomes unsure: “I wonder (more...)
Yesterday was the first meeting of the newly restarted Arizona Oracle User Group, AZORA. It was a good first meeting to kick off what I hope will turn into an active club.
We met in the Tempe Public Library in a large downstairs room with a projector screen and plenty of seating with tables so it was easy to take notes. We also had snacks. I got a Paradise Bakery chocolate chip (more...)
Fellow Phoenicians (citizens of the Phoenix, Arizona area):
This is a reminder that tomorrow is the first meeting of the newly reborn (risen from the ashes) Arizona Oracle User Group. Here are the meeting details: url
I hope to meet some of my fellow Phoenix area DBAs tomorrow afternoon.
