Operating Systems

Welcome to the new VSE/ESA column, which is designed to keep you up-to-date on current issues in the VSE/ESA world. If you have information you would like to see included, please send me an e-mail at pclark@cprsystems.com.

First order of business: It’s been a while since VSE/ESA had this type of forum, and it sure is great to have it available once again. In order to make the most of this new column, we need your help to determine what topics are of interest to you and how best to cover them. Let’s get started by examining two information items and the STACK command.

VSE/ESA 2.6.3 and VSE/ESA 2.7.2

Installation experiences with the two latest refreshes of VSE/ESA continue to be smooth and painless. There’s no reason not to move to the most current release supported by the hardware installed in the data center. With whichever release you install, be sure to order the Support Center install information and late-breaking PTFs to prevent rediscovery of issues already resolved.

z/VSE

IBM in Boeblingen, Germany, has indicated that a new version of VSE/ESA will be delivered in 2005. This new version, z/VSE, will support the features of z/Architecture hardware.

z/VSE will not implement 64-bit storage addressability for VSE; the perception is that VSE customers don’t need storage addressability greater that 31-bit at this time. That perception seems very reasonable, as no one seems to know of a VSE customer even close to being storage-constrained using 31-bit addressability.

More welcome news is that, while this will be a new version of VSE with new features and new function, the version-to-version upgrade is designed to be revenue-neutral for like function. Translation: The cost of z/VSE should be the same as VSE/ESA 2.x on the same hardware with the same software options.
