Alert: biIOMode char <> "reliable"

What does it mean? What do I do about it?

Example alert from the ProTop Portal:

What does it mean?

The database is running with the -r parameter in effect.  Use Non-reliable I/O (-r) to enable buffered I/O to the before-image file. In most cases, please avoid using this parameter because it might put database integrity at risk.  

In general, you always want complete database integrity or fast performance for large tasks, such as loading large amounts of data or doing fiscal year-end processing. The -r parameter does not guarantee complete database integrity, and No Crash Protection (-i) is faster.

What to do?

Be sure you are using this startup parameter with full knowledge of the implications.
