ICSF is supported in a SYSPLEX environment. The CKDS, PKDS and TKDS can be shared across systems in a sysplex.

Attention: If you are running on a z990, z890, z9 EC, z9 BC, z10 EC, z10 BC, or z196 and wish to share your CKDS and PKDS with another system, such as a CCF system on a z900, you should initialize the CKDS and PKDS on the CCF system.
