Oracle PL/SQL Subprogram Conditionals and Variables

This article is excerpted from chapter 36 of the book Beginning PHP and Oracle: From Novice to Professional, written by W. Jason Gilmore and Bob Bryla (Apress; ISBN: 1590597702).
Stored procedures can both accept input parameters and return parameters back to the caller.

Well, I’ve finally reached another “landmark” number in the page views – 2,000,000 views (after four and a half years) – so it’s time for a little statistical summary for comparison with the last landmark.

Looking at just the results for the last 12 months, here are some numbers in different categories.

Exadata Part VI: Cell Administration with dcli

An Exadata Database Machine X2-2 Full Rack comes with 8 Database Nodes and 14 Storage Servers (Cells). The Cell Administration can be done on the command line as user celladmin with CellCLI, as shown in previous postings already, but it would be an annoying task to do all commands 14 times.

Off topic: 'A' Week

Heck, Tim does it all the time ;-)

Furthermore, your Data Guard configuration will break as well, since the SYS account is used to log in to the standby database.

I can relate...

It is not often a simple picture and caption will make me laugh out loud - but this did. I feel like that some days... Most days now I guess :)

Relinking causes many warning on AIX for 11.2.0

DBMS_STATS.SET_TABLE_STATS and statistic staleness

Recently at work there was a discussion regarding setting optimiser statistics using DBMS_STATS SET_*_STATISTICS procedures. The question was asked:

If we set the statistics ourselves will the automatic stat’s job not overwrite them the following night?

Now I was confident that this was not the case but, having never tested this explicitly, thought it better to get my facts straight.

First some quotes from the Oracle Documentation
