In Opensips there is an option to cache all the db_text at startup or to scan the dbtext every time it is queried by using the following line in the opensips.cfg file:
modparam("db_text", "db_mode", 0)
My question is if it is possible to change this behavior at runtime, or do I need to change the config file and restart the server every time?
The db_mode module parameter of db_text cannot be changed at runtime.
Depending on your needs, however, db_mode = 0 combined with occasional dbt_reload MI commands might be superior to using on-demand caching (db_mode = 1).
