Alex,
as Oz Mortimer told you if you start FS with parameter -nosql you can’t get information of active calls.

You start up with -nosql, but things like show channels will not work

This is because FS is using an “internal” sqlite database for storing some basic informations (very basic, NO CDR!), and therefore it’s not taking too much storage space, so in my opinion there is no need to disable SQL as you will not gain any performance disabling it. 
If you disable the internal database you will not have the ability to check call status on fs_cli (in my point of view this is worse!)

BTW, if you are trying to disable the database because you believe that could be some performance issues then if you follow this guide (https://freeswitch.org/confluence/display/FREESWITCH/Performance+Testing+and+Configurations) under section "FreeSWITCH's core.db I/O Bottleneck” you will find that you can put the database into a RAM disk, so you will not impact on performance and on each reboot the database is deleted.

Cheers
Max

Hello, by default freeswitch uses sqlite db in a core.
And, as I know, FS can`t working without any DB.

when I run with full debug log (fsctl debug_level 10) I have the next error:
[ALERT] sofia_glue.c:2455 Reuse Unused Cached DB handle db="sofia_reg_external",type="core_db" [CORE_DB]
that is coming from function: _switch_cache_db_get_db_handle() in switch_core_sqldb.c that checked to what DB FS has connection.
