Hi Daniel,

Finally as you suggested in the answer we do change DB and then force a reload of the status of the nodes through the *ds_reload* MI command ( http://kamailio.org/docs/modules/stable/modules_k/dispatcher.html#id2513000) and it works great

Thanks.

Hello,

I'm using dispatcher module for load balancnig purposes I read active/inactive nodes from the database

So I define on my kamailio.cfg: modparam("dispatcher", "db_url", "mysql://openser:openserrw@ <DB_IP>/openser")

Then, on my route(DISPATCH) I call:

• ds_select_dst("1", "4");*
• t_relay();*

My question is: Which *set of addresses is using **ds_select_dst *to choose destination. Will it do a query on the db each time updating active and inactive nodes on each ds_select_dst call? If not, when is the list of addresses to choose updated? (on kamaiilio restart, periodically...) I say this because I would like to update active and inactive nodes from a 3rd party application modifying the flags column but I need to know also how many time will it take for the change to be applied.

the list of addresses is loaded at startup. To reload it, you have to send a MI/RPC command (e.g., 'kamctl fifo ds_reload', or 'sercmd dispatcher.reload', or via xmlrpc). If you just want to change the flags, there is a mi/rpc command for it:
