SETXCF FUNCTIONS command

Use the SETXCF FUNCTIONS command to enable or disable optional functions provided by the XCF and XES components of z/OS. The SETXCF FUNCTIONS command is effective only on the system where the command was issued (system scope only).

 
SETXCF FUNCTIONS, {ENABLE=(function[,function …]) }
                  {DISABLE=(function[,function …])}

ENABLE=(function[,function …]): Enables one or more optional functions. The parentheses can be omitted if only one function is specified.
DISABLE=(function[,function …]): Disables one or more optional functions. The parentheses can be omitted if only one function is specified.

See topic "The FUNCTIONS Statement" in z/OS MVS Setting Up a Sysplex for a description of the optional functions currently defined.
