Through the CONTROL, SET, and VARY commands, you
can change some of the characteristics specified in CONSOLxx.
- In shared mode, the changes made through these commands can last
the life of the sysplex.
- In distributed mode, the changes can only persist while the console
is active. When the console is activated, the attributes of the console
are always obtained from CONSOLxx for MCS, SMCS, HMCS, or subsystem
consoles.
Note that if the console is inactive, the request to change the
console attribute will be rejected (with a few exceptions). See the
specific command description in
z/OS MVS System Commands for
more details.
For example, when system S1 is IPLed into a sysplex, the console
CONS1 is defined in the CONSOLxx member with AUTH(INFO). The operator
enters a VARY CN(CONS1),AUTH=SYS to give the console a higher authority.
System S1 is then removed from the sysplex. When S1 is IPLed and the
CONSOLxx member is processed, the definition of CONS1 results in message
IEA196I, which indicates that the AUTH parameter is ignored. CONS1
will continue to have SYS authority.
For more information, see z/OS MVS System Commands.
CONSOLxx contains four optional statement types:
- CONSOLE, which is optional if processor supports the
system console. If not, a CONSOLE statement is required for the first
system in a sysplex.
- INIT
- HARDCOPY
- DEFAULT.
