Try using strace or truss to see what the underlying open failure is (if
any).

Having such a utility would solve a lot of my problems regarding getting
data into the DB.  My current application does not allow access to the
data until the DB is populated so (in this case) I don't derive any
benefit from locking, journalling, etc.

Once the DB is populated I find SQLite to more than fast enough.

I didn't think it was possible to change "java.library.path" after the
VM has started. If it is possible to change this value then that may
have an adverse affect on other plugins.  Or is the change isolated just
to the plugin itself?

Do you mind posting your plugin Activator that sets this property?

[sqlite] Busy timeout and prepare statements

2007-02-07 Thread McDermott, Andrew
Hi,

I'm seeking some clarification regarding set_busy_timeout().  If I set
this to some positive value does this work when using prepared
statements (prepare, step, reset) or only when using sqlite3_exec().

Thanks.
