Hi,

We have some 80 lpars at our shop.
I am in XXXX Lpar and able to submit a job in YYYY lpar by using
Code:
/*JOBPARM S=YYYY
in the JCL. So I believe there is a connection of some sort between the 2 lpars or a shared environment, IDK. Can u pls say how this works?

Could you pls let me know how to find the list of lpars that are connected to XXXX lpar, which would allow job submisssion via /*JOBPARM S= statement.

Let me know if I am no clear. Thanks.

The info You ask for is defined in the appropriate system parameters libraries!

we do not know anything about Your role in Your organization!
so is against the ethics to tell look here, look there!
You might end up accessing datasets You are not allowed to,
and Your security auditors might not like it!

if You have the need to know Your support will gladly provide the info You ask for

for a general insight You might want to look at

http://publibz.boulder.ibm.com/zoslib/pdf/zosbasic.pdf

or at
ABC of ZOS system programming volume 10
http://www.redbooks.ibm.com/abstracts/sg246990.html

or at the whole series of the ABC of ZOS system programming

Contact your site support group to get this type of data. They are the ones who would know how your machine is configured.

The specific facility is called XCF, which stands for cross-system coupling facility and allows applications in a sysplex to communicate across the LPARs. If you have authority, you can find the LPAR connections with the console command D XCF -- and there's a lot of options for the command that you can look up in the manual.

there is no relation between the XDC concept and the jobparm SYSAFF
which is related only to the jes2 MAS configurartion

the sysaff is processed by jes and does not care about the lpar configuration
( JES MAS configuration might take advantage from CF hardware, but a shared spool environment is all that is needed )

see ...

Enrico,

Are u saying that the entries in "Members in the MAS" under JES 2 are the actual connected entities?

Thanks.
