If it is a MONOPLEX with no serialization interchange with other Lpars, then GRS=NONE

So based on what the manual says you need to have CTCs that GRS will manage. Just out of curiosity is there going to be more then one lpar using this software? How global resource serialization works. Depending on the level of z/OS and XCF environment the systems are running in, sysplex or non-sysplex, a global resource serialization complex consists of one or more systems: • Connected to each other in a ring configuration through: – XCF signaling paths, through CTC or coupling facility – Global resource serialization managed channel-to-channel (CTC) adapter - Systems in the same sysplex must use XCF signaling - Non-sysplex or monplex systems must use GRS-managed CTCs to communicate • Connected to each other in a star configuration through: – XCF signaling paths, through CTC or coupling facility – A GRS coupling facility lock structure Paul -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Mark Jacobs Sent: Thursday, June 20, 2024 8:06 AM To: [email protected] Subject: Re: GRS in MONOPLEX without physical CTCs ?
