Enabling or Disabling Error Dumping for the
PATHMON Processes
In this example, new server processes in distributed server classes associated with the
NODE object SERVER1 will continue to be distributed among CPUs 1, 3, 5, 6, and 9,
but the relative distribution of servers among the first four of these CPUs will change.
New server processes in distributed server classes associated with the NODE object
SERVER2, however, will be distributed among CPUs 1, 5, and 9 only; for these server
classes, no new servers will be created in CPUs 3 and 6.
Changes to CPU resource assignments made with the CONTROL NODE command are
saved in the current configuration in the SuperCTL file, but not in the initial
configuration. Therefore, these values are preserved through a cool start or a warm start
of the Pathway/XM environment, but not through a cold start. When the Pathway/XM
environment is cold started, the CPU resource assignments return to their initial
configured values.
For the syntax of the CONTROL NODE command, refer to CONTROL NODE
on
page 11-9.
Enabling or Disabling Error Dumping for the PATHMON Processes
You can use the CONTROL PATHMON command to enable or disable error dumping
for the PATHMON processes in a running Pathway/XM environment. For example, to
enable PATHMON error dumping after it has previously been disabled (or if it was
configured to OFF), enter the following:
>> CONTROL PATHMON, DUMP ON
The DUMP option setting for the PATHMON processes is saved in the PATHCTL files,
but not in the SuperCTL file. Therefore, changes to this option are preserved through a
warm start of the Pathway/XM environment, but not through a cool start or a cold start.
When the Pathway/XM environment is cold started, the DUMP setting for the
PATHMON processes returns to its initial configured value.
Because PATHMON processes in a Pathway/XM environment use internal dump-file
names, you cannot define or change the name of a PATHMON dump file. The
PATHMON processes create their dump files on the same volume and subvolume as the
configuration file for that PATHMON process. PATHMON dump file names are of the
form ZZPMnnn, where nnn is a three-digit integer that forms a unique file name on the
physical (Expand) node where the dump file resides.
For the syntax of the CONTROL PATHMON command, refer to CONTROL
PATHMON on page 11-11.
Monitoring Pathsend Requesters and LINKMON
Processes
The Pathsend environment consists of Pathsend requester processes and LINKMON
processes. This subsection applies only if you use Pathsend requesters in your
Pathway/XM environment.
