Re: Access path / index rebuilds

[Evan Harris <spanner@xxxxxxxxxx>]

Hi Justin

My understanding is that the system is building an index over the 
file for use by a query (in the SQL sense of the word) of some sort. 
Since the index the SQL optimizer has determined is required to run 
the query does not exist (or has not been located) the system is building it.

Hope this helps

Evan Harris
