database hidden parameters

Hello,

how can we make sure the value of hidden parameter set in our databases?

I checked in v$parameter, v$parameter2 which gives no value

Basically in our 12C database and EBS R12.1.3 , i am trying to look the value for _sqlexec_progression_cost and using below query it seems the value is 1000 is it listing default value or the current value set now.

SQL> select KSPPSTVL from x$ksppsv where indx = (select indx from x$ksppi where KSPPINM like '%sqlexec_progression_cost%');

KSPPSTVL

1000
