We have a homegrown utility that will take a file name and use that
to determine any dependent logical files and build a list of
physical/logical file names and then search the system source code
for their use.
The second step is to also search any queries that might be using the
file or one of its logicals.
To search the queries we issue a DMPOBJ OBJ(YOURLIB/YOURQRY)
OBJTYPE(*QRYDFN) command which produces a spool file that we can then
copy to a data file and scan the data file for the file name(s).
So we ran this utility last night it reported a file name being used
by a query, but when we examined the query we found there was only
one file used in the file selection, and that file didn't have any
dependent logical files on that physical.
So we are kind of stumped as to why the dump shows a file being used
that clearly isn't. Could this dump data be residual from perhaps an
earlier use where maybe the file name seen in the dump was used in
this query?
Or is there a better way to determine what queries use a file (and or
its associated logical files)?
