A few things come to mind - but bear in mind, I have no specific qdb (nor qad) experience :-)

- have you made sure there's no character set differences (eg, UTF vs ascii) between various encodings of the filenames?

- are you sure there are no special characters somewhere in one of those strings (these sometimes occur with copy&paste 
between windows and other OSs)?
- can you create the db file manually (ie, "touch")?
- you have quite a high verbosity for qdb ... is there anything meaningful in the logs?

Hello all,
I try to create and start a qdb database for QNX 7.00  with the following command:
# qdb -vvvvvv -otempstore=/opt/qdb_database/tmpstore/ -Rauto -A

Even if the qdb process is started correctly and even though I do not receive any error message, the file:
"/opt/qdb_database/qad_proc_database_file_db"
is not created as I expect and as it is instructed to to in the " /pps/qnx/qdb/config/qdb.conf " file (see below)

Subsequently when I try to run my c application:
" hdl = qdb_connect("/opt/qdb_database/qad_proc_database_file_db", 0);"

I get the error message: "Error connecting to database: No such file or directory"

Can anyone help me with this one?
