pdb中执行shutdown immediate会怎样？

开启THREADED_EXECUTION会造成什么影响？

THREADED_EXECUTION 指定是否启用多线程Oracle模型。

属性 描述
参数类型 布尔型
默认值 false
可修改的 没有
可在PDB中修改 没有
取值范围 `true false`
基本的 没有
甲骨文RAC 如果指定，则所有实例必须使用相同的值

从Oracle数据库12 c开始，多线程Oracle模型使UNIX和Linux上的Oracle进程能够作为操作系统线程在单独的地址空间中运行。

默认情况下，UNIX和Linux上的某些后台进程始终使用线程执行。其余的Oracle进程作为操作系统进程运行。因此，“ Oracle进程”并不总是等同于“操作系统进程”。

注意：

When this initialization parameter is set to TRUE, which enables the multithreaded Oracle model, operating system authentication is not supported. Attempts to connect to the database using operating system authentication (for example, CONNECT / AS SYSDBA or CONNECT / ) when this initialization parameter is set to TRUE receive an ORA-01031 "insufficient privileges" error.

如果将此初始化参数设置为TRUE，则启用多线程Oracle模型，则不支持操作系统身份验证。当将此初始化参数设置为接收错误时，尝试使用操作系统身份验证（例如CONNECT / AS SYSDBA或CONNECT /）连接到数据库。 TRUE``ORA-01031 "insufficient privileges"

解决此错误的方法是在连接数据库时始终使用密码。

另外，当此初始化参数设置为时TRUE，DEDICATED_THROUGH_BROKER_listener-name``=ON应将参数添加到listener.ora文件中，其中listener-nameOracle Net监听器的名称为，LOCAL_LISTENER初始化参数应设置为与您的实例服务相对应的TNS名称条目。这样，当通过侦听器请求与数据库的连接时，服务器就可以生成线程。
