z/VSE 6.2 considerations for TCP/IP stacks

With z/VSE 6.2 (and z/VSE 6.1) you will get new version of IBM TCP/IP for z/VSE - Version 2 - and a new release of IPv6/VSE - 1.3.
TCP/IP license keys only change, if you get to a new version. That is you can still use your IBM IPv6/VSE V1 key. For IBM TCP/IP for z/VSE V2 (and the GPS feature), however, you need to request a new license key from the IBM key center.
If you order z/VSE 6.2 via IBM Shopz, you need to select the TCP/IP product (and other products) too. The TCP/IP cover letter holds the contact information of the key center.
IBM TCP/IP for z/VSE and IBM IPv6/VSE come preinstalled with z/VSE 6.2.
Please run the delete job for the TCP/IP product you don't use. Skeletons are in ICCF library 59 - DELTCPIP for TCP/IP for z/VSE 2.2 and DELIPV6 for IBM IPV6/VSE 1.3.
IBM TCP/IP for z/VSE (and VSE/ESA) is installled in the VSE sublibrary PRD2.TCPIPC.
IBM IPv6/VSE is installed in VSE sublibrary PRD2.TCPIPB.
Please check your LIBDEF statements of your TCP/IP startup job, if they contain the correct product sublibraries. Ensure that CUSTDEF.PHASE and PRODKEYS.PHASE can be found in the sublibraries of the LIBDEF chain in your TCP/IP startup job.
Otherwise you may get the following message: IPN110E Product key validation failed for Stack reason=GETKNFNB and the job terminates.
