So on most (but by no means all) systems, a TSO user's data sets have names that have the user ID as the high-level qualifier.? Also conventionally, this means that some sort of user (meaning

Hi, For home use any more than 2 cores adds no extra to performance. Hercules will use one for CPU emulation and one for IO and other processing. Generally, Hercules can emulate one less Mainframe CPU

Usually one user job is going to be limited to one CPU. Running one batch job is going to max out one CPU with another CPU handling I/O and a third handling some MVS / Hercules / base overhead.

Hi I am newbie in Mainframe and Hercules and Hyperion. When i run something in guest my host shows approximately 20% of CPU usage or hard usage. I want to tune and optimize Hercules with parameters of

IBM created the format for using the system based on their design BUT they were one of the first in creating a commercial computer system from scratch starting with the 1401 and for science based the

That's a bit harsh. They also "made up" the hardware and the whole OS and the restrictions on file names too. And /surely/ they designed SPF with this naming approach because their own programmers, or

It does make sense, because IBM's security products can allow you to change or create datasets with certain HLQs (High Level Qualifier, the first part of a dataset name) such as your userid. And TSO

Hello, same here! tk4- update 09 would be a great gift for xmas. I would gladly volunteer to be a tester if you need any.. -don Sent from my iPad Air 2

Thank you all for the explanations. So it boils down to "IBM made it up" :)? when it mapped these notions of "department", "project", "tool" ("type") to the 44 characters of DSNAMEs.? Is that right?

Actually, the search order would be project.library1.type, project.library2.type, project.library3.type. etc. Charles Bailey

Both RPF and RFE are imitating the style of an IBM program product introduced in the 1970's called Structured Programming Facility (SPF). (Later, they changed the acronym to mean System Productivity

If you are new to this stuff, it's worth keeping in mind how it fits together. Hercules emulates mainframe hardware. The Hercules console lets you behave as an operator and systems programmer. MVS is

That format of the 3 different levels were done in the PDF / ISPF product and copied as a user interface. Saves will go into the project1.library.type while an open will try project1, project2,

Hi I am going back and forth playing with MVS in various forms. I still need quite a bit of help in understanding many of the conventions that seem to be used while using MVS.? I am using REVIEW and

Hi All (and especially Jürgen), Have the various issues holding up the next release of tk4 been resolved yet? Is there any possibility of a Christmas present of a new tk4 this year? Peter

Good idea. Thanks. I need to check versions of quite a few things, and now is as good a time as any :-) Roops
