z/VSE 6.1 comes with new TCP/IP stack versions / releases - IBM TCP/IP for z/VSE 2.1 and IBM IPv6/VSE 1.2.
Because of the version change of IBM TCP/IP for z/VSE (1.5F -> 2.1) IBM TCP/IP for z/VSE V2.1 requires a new license and license key.
You may also use the Migration Pricing Option (MPO) for this new TCP/IP version.
DY47668: UPDATE FOR IBM TCP/IP FOR Z/VSE V2.1 PRODUCT KEY VALIDATION.
We just released APAR DY47668 (PTF UD54187), that implements a fix in the IBM key validation to no longer accept old IBM TCP/IP for VSE/ESA V1 keys.
That is before applying this PTF ensure that you have a valid IBM TCP/IP for z/VSE 2.1 license and license key available.
If you are ready to apply the PTF, I recommend the following procedure:
- apply PTF UD54187
- modify your license key member (replace the old IBM TCP/IP for VSE/ESA application pak license key with the new IBM TCP/IP for z/VSE 2.1 license key)
- catalog the updated member. If the new key is not cataloged, you will be in demo mode after the TCP/IP restart (corresponding messages are displayed).
- shutdown your IBM TCP/IP for z/VSE 2.1 partitions, if still running
- restart the IBM TCP/IP for z/VSE 2.1 partitions
Your TCP/IP stack will successfully initialize and your new license key is active.
Only customers that license TCP/IP for z/VSE 2.1 from IBM are affected by this license key change.
Please let me know, if you have any questions.
