Two or more correctly set up Hercules instances on the same or different PCâs with the same CPUSERIAL and different LPARNUM / LPARNAME settings will look to z/OS as different LPARâs on a single machine. I myself have not (yet) done so on a single PC though, but agree with others that also this should be no problem. On multiple PCâs you may want to ensure a consistent time clock, e.g. using NTP (also available under Windows).
As sysplex is being mentioned, please note that base sysplex coupling using XCF is possible and working fine using Hercules CTCE devices. z/VM is not needed for that, although the z/OS base sysplex members can also run under z/VM, even under different Single System Image (SSI) z/VM members on different PC hosts.

Post by ***@yahoo.com [hercules-390]Hi,
I need two LPAR for setup sysplex environment.
Can we run 2 instance in same computer?
Kindly share the link or discussion on this before.

No link, but multiple instances of hercules is easy.
The trick is using zVM for coupling software.
To run multiple hercules instances, you must update the
hercules configuration files to not step on each others
IP ports.
See CNSLPORT and either HTTPPORT or "HTTP PORT"
depending on the hercules release.
If sharing disk between systems, you will need SHRDPORT on
one instance but if on both, they must have different IP ports.
