oracle專用模式修改為共享模式
沒有返回值,說明處於專用模式:
SQL> select * from v$dispatcher;
未選定行
SQL> show parameter shared_ser
NAME TYPE VALUE
max_shared_servers integer
shared_server_sessions integer
shared_servers integer 0
線上修改共享伺服器程序的數量
SQL> alter system set shared_servers=5 scope=both;
系統已更改。
SQL> show parameter shared_servers
NAME TYPE VALUE
max_shared_servers integer
shared_servers integer 5
SQL>
配置dispatchersDispatchers引數用於配置共享模式架構中dispatcher程序,共享模式只少需要一個dispatcher程序。
SQL> alter system set dispatchers='(PROTOCOL=TCP) (dispatchers=3)' scope=both;
系統已更改。
再次檢視
SQL> select * from v$dispatcher;
