You might not need a z/OS license for software running inside
the penguin, but you would still need licenses for all your
other z/OS software, and they would include the CP's that the
penguin is running

Ah now I understand the buggy problems with so many programs that were
certified as correct.
They haven't yet reached the very correct level yet ;-)
Hey we can take mathematics to a whole new level, why stop at infinite,
we can now have very infinite ;-)

Except the original poster wants to REDUCE z/OS cycles and cost, not
INCREASE them.

Very true! That is why, back when I had z/Linux, I only allowed direct
access

I imagine that running commercial software inside a penguin on z/OS
would not require a z/OS licence any more than it does when the
penguin's running on z/VM. A penny saved is a penny saved.

I'm sure Why bother was asked about Linux (and Solaris) on System/390

Linux disk can be served (like NFS or SAMBA).
Mainframe disk can be served to Linux (thinking LANRES).
And, of course, there is FTP servers.
Perhaps even Java beans, kind of like what we have on VSE to serve VSAM.
But native reading/writing of anothers filesystem, can be done if you write the
to linux
bypassing as much security as you can and then stop using the z/OS copy
of the data.

One of my managers told me that since you could make both ECKD (FICON)

Along with security (which is a huge problem) a production quality native
file-system driver would have to deal with:
- serialization (GRS/XCF enqueues with z/OS)
- support for z/OS catalogs
- support for dealing with variable length binary records.
- support for datasets with extents that span

First, a confession: I am the one who wrote the device driver that
enables accessing z/OS dasd from z/Linux.
Regarding the security issues that were raised here: They are valid and
I agree with what was said. However, *if* you have a z/OS volume
accessible from z/Linux with or without a driver,

I am pretty sure it would take at least a new driver and probably a new

cannot validate any of the linux i/o to each file. Any
