Paragraph reads:

We've designed the exercises as a way to get you to try things out in your own
environment. Generally, there are no single, correct answers. The results from a
given exercise will be specific to your systems.

After the existing "value" field paragraph, added the following paragraph:

When no value field is emitted to the trace file, it is an indication that the NULL value has been
bound into the placeholder variable. For example, in the fnd_profile.get_specific sample shown
earlier, the absence of a value field for bind 4 indicates that the application has provided the NULL
value for the :val placeholder. The bind value length specification of zero (avl=00) is corroborative
evidence.

The sidebar mentioned an estimate of 10**80 atoms in the universe, and cites a
siencenet.org.uk URL as one of the sources for that estimate. That URL no longer
functions.

On page 173 in the section Un-Instrumented Oracle Kernel Code, the 2nd paragraph
reads: u201cChapter 12 lists the number of code segments that are instrumented...u201d

Does this refer to Table 11-1 on page 306 and should therefore read: u201cChapter 11...?u201d

Reader is correct. The right reference now reads Table 11-1.
