Yes! Could this help?
Sorry for this stupid question, I've read the man pages... it's a wonderful
command!
Thank you Jay!

If some other program has the file open it will tell you.
When you get a lockup use it to figure

In the source code at the begin of the two processes that execute queries on
the database I've used the code:
srand(time(NULL));
to avoid collisions...
(I never started the two processes at the same instant)
That should work great.

Try using sqlite3_busy_timeout(), to get round the temporary locks if
possible. SQLite will retry locked database access until the command
either succeeds or times out.

If this does not fix your problem, it is possible that an

Laura,
'df -h' should give you some hints, or 'showmount'. I run on BSD not
Linux,
but most unix like OS's will tell you if the mount point is a hard drive
or a remote mount, in which case, it will have a hostname:/path instead of
a /dev/dsk device file as the device/partition information.

This looks like it should work fine.
The only thing that concerns me is this could be a very long loop
if something locks the table or there's an error that's not recoverable.
It would sit there forever retrying something that will never be fixed.
Some operations will cause the database to be

Hi all,
I'm a software developer and I'm using sqlite3 for my application in c++.
This is the problem I've found:
two processes do queries (about 1 query per second) on one database; the
