Dubugging parameters

Can anybody guide me about below debugging parameters,

when those parameters required?

What will happen if I remove them from notes.ini?

AGENTTHREADDEBUG=1

DEBUGJAVAAGENTTID=1

DEBUG_THREADID=1

Pls suggest…

You do not need any debug parameters unless you are troubleshooting a specific issue, usually under the direction of an IBM support engineer.
