SET CONFIGMODE

OFF command. This method causes CP to perform the overhead once at the
beginning and once at the end, rather than before and after each individual
command.
3. There is only one dynamic I/O command that you cannot issue while in
configuration mode: the SET DYNAMIC_I/O OFF command. You must issue
SET DYNAMIC_I/O OFF as an individual command. For more information about
the SET DYNAMIC_I/O command, see page 1247.
4. When you use the dynamic I/O commands, you are changing the I/O
configuration as the software (CP) understands it. You must also change the I/O
configuration as the hardware understands it. To do so, you must update the
IOCP source file and issue the SET IOCDS_ACTIVE command (page 1258).
5. If you are in configuration mode and you issue a dynamic I/O command that
does not complete successfully, CP automatically takes you out of configuration
mode.
6. If you are in configuration mode and any of the following occur:
v The system abends,
v The system loses power,
v You issue a SHUTDOWN REIPL command,
v You issue a CLEAR RESET from the hardware console, or
v You issue a LOAD CLEAR from the hardware console.
CP takes you out of configuration mode before shutting down the system.
7. To display whether the processor is currently in configuration mode, use the
QUERY CONFIGMODE command (page 717).
