How can I lock a sqlite database?

Question

We\'ve had issues in the past where a rogue process was keeping a sqlite db locked. I\'ve written some code to notify us if this is happening, but need to test it.

Execute these statements:

PRAGMA locking_mode = EXCLUSIVE;
BEGIN EXCLUSIVE;

This will lock whole database until you execute:

COMMIT;

For simplicity, you can do this using sqlite3 command line utility.
