When to use the Oracle ANALYZE command and how to avoid complications

An expert explains when and how the Oracle ANALYZE command should be used and provides examples to help you avoid complications when using the command.

Are there any "side effects" associated with using the Oracle ANALYZE command?

The book that I am reading mentions what this command does and it provides a few good examples, but it does not...

mention possible complications of running the command and under what conditions the command should not be used.

You did not specify your version, but if you are using Oracle 10g and higher, then you should use the DBMS_STATS package to calculate Optimizer Statistics. The ANALYE command should only be used to do things like LIST CHAINED ROWS. The DBMS_STATS package is much more robust for Optimizer Statistics and replaces the ANALYZE command for this functionality.
