生产环境下的包编译。这会导致任何问题吗?
我们最大的客户(1500亿美元的营业额)担心在线生产期间编译包会导致数据库挂起。
我认为这是不可能的,因为我想要编译的包是单独且孤立的。它们用于纠正数据或分析数据。
我的领导告诉过我一些关于SGA的事情吗?是否可以?
你觉得怎么样?
Our biggest client (150 billion $ of turnover) is afraid about compiling package during the online production time can cause database to hang.
I think it is impossible since the package I want to compile are alone and isolated. They are used to correct data or to analize them.
My chief told something about SGA? Is it possible?
What do you think about?

在以下情况下,在在线生产中编译 PL/SQL 包会出现问题:
前者可以阻止会话(最有可能只是由于库缓存引脚锁定而编译包的那个),后一个将导致在编译后尝试再次使用该包的所有会话中出现以下错误消息:
我认为没有任何特定的信息与SGA相关的问题。
Compiling a PL/SQL package in online production is problematic if:
The former can block sessions (most likely just the one that compiles the packages due to a library cache pin lock), the latter one will lead to the following error message in all session that try to use the package again after the compiliation:
I don't think there's any specific problem related to the SGA.
