Oracle scheduler max_jobs_Slave_processes is set to null, how many will be allocated?

Question

Executing the following query against my database:

select value 
from dba_scheduler_global_attribute
where attribute_name='MAX_JOB_SLAVE_PROCESSES';

yields a value of NULL. My question is what is the maximum number of slave processes that could be allocated, for job runs, when this value is set to null?

Answer 1

NULL implies no limits. Anything other than NULL sets a limit.

See the documentation here.
