Hi s390x Gurus
I´m new to Linux on z and we are conducting a POC test of Linux Red Hat
with Oracle running under z/VM 5.4 RSU 1003
and a z/10 BC model A00 (IFL Only).
If linux virtual machine is defined with 64G in directory we got an
abend during startup (see below). Doing some tests I found that I
can define it until 59G in directory (60794036k from TOP linux command)
and it will startup correctly.
My questions are:
1 - Is this a limitation of linux s390x or Red Hat distribution?
2 - Is this a linux s390x bug or Red Hat distribution?
3 - How can I circunvent this so we can continue with POC (Proof Of
Concept)?
Thanks in advance for all hints and tips about.
