<tt>Hi Gunjan,<br>
<br>
In dispatcher there are 2 storages:<br>
- primary storage which is in memory<br>
- secondary storage (read only at startup or reload) which is
the DB<br>
<br>
First is about synchronizing the 2 storages (from secondary to
primary via a ds_reload command). AFter that is about which
storage you are querying for data. Like the "opensipsctl fifo
ds_list" (via MI command) gets data from memory cache while the
"opensipsctl dispatcher show" simply dumps db content.<br>
<br>
