z/VSE Details

Delivery of the 31-bit VTAM support for I/O buffers means a lot to z/VSE users with large VTAM-based communications networks. In earlier releases, those buffers were in 24-bit System GETVIS, so moving them is a big deal for many users.

POWER support for automatic spool deletions, POFFLOAD enhancements, and spool entry duplication with different attributes and a common data deliver significant functional benefit to numerous users.

The aforementioned 64-bit real memory support is transparent to your applications and requires nothing other than installing z/VSE Version 4.1. To run without paging (think Page Data Set), the NOPDS IPL option must be enabled and the DPD IPL statement deleted.

The Open System Adapter (OSA) for NCP enables a Linux-supported NCP using an OSA Express2 adapter to appear to z/VSE as if it were a channel-attached 3745 Communication Controller.

Migration Details

The easiest migration will be from VSE/ESA 2.7 (non- FBA) or z/VSE 3.1 via the FSU. If you aren’t on these releases, then a base install with tailoring and a user migration will be necessary. Nothing really new here, just business as usual.

z/VSE 4.1 will be available on tape (3480 compressed, 3590, or 3592), CD, or download (via ShopzSeries). Documentation is available on CD or DVD in PDF and Book Manager formats.

z/VSE 4.1. requires z/VM 5.2 to run as a VM guest. To use the newer z/VSE 4.1/Linux facilities, you will need a new Linux release.

Software Cost

There are several new software pricing options and it will pay you to investigate them. This will require some effort on your part, but could prove very worthwhile by providing you the insight to reduce your software costs.

The new z/VSE 4.1 sub-capacity pricing option should be investigated to see if it is to your advantage to use it. It appears that some third-party software companies also are investigating offering a sub-capacity pricing option. The typical software pricing options also are still available. Software cost options deserve a z/Journal article just to investigate and acquaint users with all the options. Hopefully, we will see that in the next issue.

Thanks for reading this column; see you all in the next issue. Z
