Yes, found it: no support for that in 3.3.8. :( Must compile newer version.

Bart,
Thanks for the pointer. It does sound quite interesting, though I don't
know if it can (easily?) be used from within a Tcl-base

If you control all SQLite clients' code, you could recompile sqlite
to use the file-based dotlockLockingStyle convention via
-DSQLITE_ENA

If your database storage device cannot guarantee an exclusive file
lock, then any database write can potentially result in corruption.
If you control all SQLite clients' code, you could recompile sqlite
to use the file-based dotlockLockingStyle convention via
-DSQLITE_ENABLE_LOCKING_STYLE=1
Hi All,
I currently have a single-user SQLite-based application that, due to
customer need, is being pushed toward multi-user access. I've done some
research on the multi-user capabilities of SQLite. It seems the general
consensus is that when the database file is stored on a network drive
