Hi,
In mode 2, the DB is periodically updated from mem. cache - what is
removed from mem, is removed from DB also.
At startup, the DB is cleaned of old, expired elements.
If you use this db_mode, you should not operate directly on DB, but only
via the mem cache (MI functions) to avoid de-synchronization. Even if
this happens, after a restart, everything will be cleaned.
This works for small installations, but not if you have an installation with
several millions customers and process 700 millions call minutes per month..
Here do you want the smallest downtime as possible, it is not feasible to
simple restart openser. The cleanup on startup would probably need also
several minutes.
But i don't know what your load requirements are.
