oracle專用模式修改成共享模式

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

在線修改共享服務器進程的數量

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參數用於配置共享模式架構中dispatcher進程，共享模式只少須要一個dispatcher進程。

SQL> alter system set dispatchers='(PROTOCOL=TCP) (dispatchers=3)' scope=both;

系統已更改。

再次查看

SQL> select * from v$dispatcher;
