The Datacom/AD 15.1 documentation section Installation in the SYSPLEX Environment says:
"...A valid CXX name can be 8 bytes in length. We recommend that you make the name 1 to 7 bytes long. Use the eighth byte for the Data Sharing or MUFplex feature.

Resolution

7 characters is suggested to allow the 8th character to be used as a suffix in the TARGET_MUF_LIST when setting up a Shadow MUF.
