Like all SAP products,we need an valid license to run SAP HANA for production systems.
SAP HANA licenses
are of following types:
- Temporary
- Permanent - Enforced and Unenforced
Permanent: SAP
provides this license upon request , this is a permanent license(no expiry
date) and can also be granted till
certain duration. Once this period is
over the license will get expired and a temporary license will be installed
automatically for 28 grace period.
Permanent license
are of two types:
Enforced: HANA
license are based on the memory usage, for example you can install a 1 TB
memory HANA system but can only license it for 256 GB usage. If the system
usage is increased over licensed amount then the system will locked down if the
license is "Enforced".
Unenforced: The
system will issue a warning upon over usage of SAP HANA licensed memory amount
but it will not get locked down.
