Hello Tony, Parwez, Alan,
Thank you very much for your advice, it'a very helpful. I'm reviewing your
comments.
I understand that the number of Ethernet ports is different for each OSA
PCHPID.
The z10 BC is a our partner's machine. I checking of OSA-Express features.
We will continue to work on the OSA's configuration.
Thank you again.
Best regards,
Toyokazu Kobayashi

1) Is the port set in OAT a OSA Physical port?
Yes. If the PCHID has two ports, then you specify port 0 or 1 in the OAT.
But be careful. On a z9, I think you have OSA-Express2. All of the PCHIDs
are single port. There are multiple PCHIDs on a *card*, but each PCHID has
only one port (port 0). The OSA-Express Customer's Guide and Reference has
pictures. The HMC/SE will also tell you what type of card you have.
2) Can OSA-ICC 3270 sessions and OSE ports share a OSA Physical port?
Should these have separate Physical ports?
You cannot share ports between OSE and OSC. The decision for OSE or OSC is
at the PCHID level.
3) Where is the physical port of the OSA-ICC session set?
In the ICC configuration on the HMC.
4) OSE is assigned to ZOS2 LPAR in the PARTITION statement.
But SHARED is also specified by CHPID.
Are OSE devices also available in ZOS1 LPARs?
No. Your IOCP says that only ZOS2 has access:
CHPID PCHID=191,PATH=(CSS(0),03),TYPE=OSE,SHARED,PARTITION=((ZOS2))
If you didn't specify PARTITION=((ZOS2)), then both LPARs would have access.
