SAP HANA永久License的类型

SAP HANA永久License又分为两种类型：非强制和强制，因为Non-Enforced和Enforced。

强制型（Enforced）的授权，授权大小是多少就是多少，当实际使用的内存量超过这个值，HANA系统将会Lock住，只有SYSTEM用户可以登录进去执行License相关的操作。

非强制类型的License，即使实际使用的内存超出了License限制，仍然能正常使用，只是会产生一些警告信息。

综上，对于使用非强制类型的License的用户，如果需要扩充内存，放心扩充即可。

官方解释：Unenforced and Enforced License Keys

There are two types of permanent license key available for SAP HANA: unenforced and enforced. If an unenforced license key is installed, the operation of SAP HANA is not affected if its memory consumption exceeds the licensed amount of memory. However, if an enforced license is installed, the database is locked down when the current memory consumption of SAP HANA exceeds the licensed amount of memory plus some tolerance. If this happens, either SAP HANA needs to be restarted, or a new license key that covers the amount of memory in use needs to be installed.
