ALTER Command
.ZDEBUG-ON-ERR
specifies how the SCP primary process responds to internal errors. Valid values
and their meanings are:
This field corresponds to the DEBUGONERROR startup parameter.
.ZBKUP-DEBUG
specifies whether or not the SCP backup process is started in debug mode when
it is next initiated. Valid values and their meanings are:
ZCMK-TKN-ALTER-BKUP-CPU
specifies a new backup process CPU assignment. This token is accepted only when
the command is directed to the SCP native object type: ZCOM-OBJ-PROCESS.
If a backup process is currently running in another CPU, it is stopped and restarted
in the new CPU. If no backup process exists, one is started in the new CPU. Event
messages describe whether the attempt to initiate a backup process in the new CPU
was successful. Valid values for this token are in the range –1 through 15.
If a value of –1 is specified, the current backup process, if one exists, is stopped.
Omit this token if you do not want to change the backup process CPU assignment.
You can also stop the backup process directly through a command interpreter with a
STOP command specifying the cpu,pin of the backup process. The primary
process immediately tries to restart the backup. Thus, stopping the backup process
with a command interpreter provides a method of restarting a new copy of the
backup process in the same CPU.
This field corresponds to the BACKUPCPU startup parameter.
ZSPI-VAL-TRUE The SCP process calls DEBUG when it detects an internal
error. The primary process does not terminate, and the
backup process does not take over until a stop command is
issued to the DEBUG process.
ZSPI-VAL-FALSE The SCP process terminates abnormally when it detects an
internal error, allowing a backup process to take over, if one
exists.
ZSPI-VAL-TRUE The SCP backup process is started in DEBUG.
ZSPI-VAL-FALSE The SCP backup process is started normally, allowing a
normal takeover.
