A deferred update requires a system restart to activate. 延期更新需要重新启动系统才能激活。
Note: This is very similar to the update of DB2 configuration parameters, where changes in some parameters take effect immediately, and some are deferred to the instance or database restart. 注意:这非常类似于DB2配置参数的更改,其中对某些参数的更改可以立即生效,有些则会等到实例或数据库重新启动之后才生效。
