Assuming the configuration information is database specific, then
one can do the search as part of the db_open(). If its overlay
specific, I believe one can overlay a db_open to do the search in.
If the configuration information is global, then you just need
to hack the startup to do additonal stuff post read_config()
but prior to starting the listener thread.
In regards to your second question, one just needs to construct
a pseudo-Operation to do the search under. There are a number of
examples of such in the code.
Have fun! Kurt
