SET SERVER Command
AUTORESTART number
specifies the number of times that the PATHMON process attempts to restart a
server process within a fixed 10-minute interval after an abnormal termination,
such as a call to the Guardian ABEND procedure.
number can be a value from 0 through 32,767. If you omit this attribute, the
default is 0.
After an abnormal failure of a server process, the action caused by this option is
equivalent to using the START SERVER command and is effective for static server
processes only.
This attribute is valid for Guardian and OSS server processes.
CPUS primary:backup | cpu
specifies the list of processors in which the server processes in this server class
run. The processors can be specified either as primary and backup processor
pairs, or as a list of single CPUs; the two types of lists cannot be mixed.
primary:backup
The PATHMON process uses this sequence of pairs in the order specified as it
creates the server processes. You can define a maximum of 16 pairs of
processor numbers; processor numbers for backup CPUs need not be unique.
If a primary processor is down, the PATHMON process exchanges the roles of
the primary and backup CPUs. For example, if you define these:
CPUS (0:1, 2:3, 4:5)
and processor 2 is down, the PATHMON process starts the servers in CPUs 0,
3, and 4.
cpu
The PATHMON process uses this sequence of individual CPUs in the order
specified as it creates the server processes. A processor can be specified only
once in the list; you can define a maximum of 16 processor numbers. The
BACKUPCPU attribute is not included in a PARAM message if a single
processor list includes only one processor.
If a processor is down, the PATHMON process uses the next processor in the
list. For example, if you define these:
CPUS (1, 3, 5)
and processor 1 is down, the PATHMON process starts the next server in
processor 3.
If you omit this attribute, the PATHMON process uses all available CPUs on the
system as primary and backup processor pairs according to an internally defined
algorithm, and sends the BACKUPCPU param.
