Like you, I could not find any documentation but I didn't look very hard
since Tivoli support told me to run it to solve a problem.  On 5.1.1.4 the
first run took about 1 hour on my 10 GB database.  I didn't check for
changes in the db size, so I don't know if the db size was reduced.  I
finally ran had to run AUDITDB FIX=YES to clean up the mess.  Be sure your
server is 5.1.1.6.
