IBM Cloud Provisioning and Management delivered multiple sysplex support in z/OS V2R3 and z/OS V2R4 releases with PTF UI66660 (z/OS V2R4) and PTF UI66659 (z/OS V2R3).
This support enables system programmers to create and manage Cloud Provisioning and Management domains which can be used to provision software service instances on systems in multiple sysplexes. Before this enhancement, Cloud Provisioning and Management domains could be used to provision software service instances on systems only in the local sysplex.
To provide multiple sysplex support Cloud Provisioning and Management utilizes capabilities in z/OSMF for a primary z/OSMF to communicate with secondary z/OSMF systems. Therefore, it is necessary to perform the setup to enable the z/OSMF-to-z/OSMF communication and to enable single sign-on between z/OSMF systems. For details see the z/OS Management Facility Configuration Guide, https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.4.0/com.ibm.zos.v2r4.izua300/IZUHPINFO_SSOSetup.htm. There is additional information in the help topic "Establishing a single sign-on environment" in the z/OSMF server on-line help.
When creating a domain, the ability to include systems from non-local/remote sysplexes is now provided. This is not available with the default domain since a unique default domain exists in Cloud Provisioning and Management on each z/OSMF system. Systems are designated in a domain by system definitions in the primary z/OSMF Systems Settings task. The nickname of the system is used to add the system to the domain.
