Yes, I meant for Jason's use case. I was involved in getting z/OS running in
the ZVDT/Wazi environment,
so I am aware of those things.

Silly question: is it risky to compress any PDS belonging to PROCLIB
concatenation?
Is it documented anywhere?
And the same for PARMLIB.

If it is really not possible to run the z machine to extract your data, I would
recommend talking to ITC about running the IBM licensable z emulator which runs
z/OS. I think it is likely they have some kind of solution for this.

Thank you very much for your response. Our historical backups are made through
DSS dumped to IBM TS7700 tape library, and the data mainly consists of IMS and

Hercules does not emulate z/OS. It emulates the hardware. You could run the
free MVS that is available. Whether or not you could use that to access your
backups is another question. You didn't say what kind of backups you have. Can
you access DFSMSdss backups without running some version of DSS?

To answer Jason's question, Hercules on LinuxONE would technically be able
to do this. However, I would strongly caution that there are significant
licensing issues involved in running any licensed program product on

Transactional execution facility instructions have not been implemented.
Has your z/OS machine stopped working or the current z/OS can't be

Just compiling and emulating Z would be a step but rather than emulating you’d
be able to execute z/OS on Z hardware which is a lot faster. zVDT provides
this and we’ve seen dramatically better performance on zLinux. That said,
there is still the pesky software license issues.

That was going to be my question too... Why?
Of course it would be fun to try, but since Jason wrote:

What is your purpose in doing this? Your Linux One machine is a zArchitecture

Replying to my own post. 99.% availability equates to about 3 sec/year.

Yes, you will need to compile Hercules on LinuxONE. There are no prebuilt
binaries for it, mainly because LinuxONE isn't among the systems that our
folks have access to. You'll need to use Linux running on the LinuxONE
system to do the download and build.
The good news is that Bill Lewis's outstan

I have experience using Hercules on Windows and understand that I need it to

Needs an OS already installed to download, compile, install Hercules
emulator. Then you install an operating system on Hercules.
