Not exactly. When client (native or not) is connected to Tuxedo then client has access to BB and does the changes by Tuxedo API - by his own, not by BBL.
BBL is some kind of health check server.
BBL periodically checks to see whether the servers it started are still running.
You can proof it by killing BBL on some machine. Native clients still can call services on this machine.
Anyway You can "tunning" BBL by 2 parameters (RESOURCES section):
SCANUNIT: Sets the granularity of checks in seconds or milliseconds:
Seconds: Must be a multiple of 2 or 5 seconds.
Milliseconds: Use 'MS' as unit and set as 0-30000.
Default is 10 sec
Seconds between sanity checks of servers
Effective for BBL: is : SANITYSCAN * SCANUNIT must be lower than 300s. Default this is 120 s
Thank you Bartek for this valuable information!
