What is the query to get the process limit on Oracle 11g? I'm getting the error:

Maximum Number Of Process Exceeded


I want to see (using a query) what the setting is in my database for the process limit.

My question is: What is the query to get the process limit on Oracle 11g?
select max(maxval) as PROCESS_LIMIT 
from dba_hist_sysmetric_summary 
where METRIC_NAME in ('Process Limit %');
