Oracle RDBMS: Easily determine what parameters are set to using sqlplus without Oracle Enterprise Manager (OEM)

This is probably unnecessaryOracle for many of the Oracle RDBMS gray beards out there 😉 but if you’re asked to provide the number of client connections. Just fire up sqlplus or whatever tool of choice:

SQL> show parameter sessions

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
java_max_sessionspace_size           integer     0
java_soft_sessionspace_limit         integer     0
license_max_sessions                 integer     0
license_sessions_warning             integer     0
sessions                             integer     784

SQL>  show parameter processes

NAME                                 TYPE        VALUE

gcs_server_processes                 integer     0
global_txn_processes                 integer     1
job_queue_processes                  integer     10
