TS/MP 2.5 System Management Manual

To take full advantage of the node-independent feature, you must invoke it by using the SET
PATHWAY NODEINDEPENDENT command prior to using the SET PATHMON commands that specify
a backup processor and dump file. For more details on how the NODEINDEPENDENT attribute
works, see “Configuring Objects in a PATHMON Environment” (page 51).
Note that setting the Pathway NODEINDEPENDENT attribute to ON overrides and disables the
node field of the CMDVOL command. For more details, see “CMDVOL Command” (page 138).
Specifying the Owner and Security Attributes
You specify security for your PATHMON environment by setting the OWNER and SECURITY
attributes. These attributes determine who is allowed to alter the definitions and states of
PATHMON-controlled objects.
For example, these commands indicate that the owner is the super ID and that only the owner can
add, modify, or delete PATHMON-controlled objects:
= SET PATHWAY OWNER 255,8
= SET PATHWAY SECURITY "O"
Configuring the PATHMON Process
Use PATHCOM commands to configure your PATHMON process. For example, you might want
to specify a backup processor or request error dumping.
Specifying a Backup Processor
Because the PATHMON process is a crucial control process, it typically runs with a backup process.
To define the backup process’s location, use the SET PATHMON command. For example, this
command selects processor 1 as the processor for the backup process:
= SET PATHMON BACKUPCPU 1
You must specify a processor other than the one in which the PATHMON primary process is
currently running.
Requesting Error Dumping
You can request error dumping by specifying either the SET PATHMON DUMP ON command or
the CONTROL PATHMON, DUMP ON command.
• Use the SET PATHMON command if you want to request error dumping and you have not yet
started your Pathway environment.
• Use the CONTROL PATHMON command if you want to request error dumping but you have
already started your Pathway environment. This command is described in more detail in
“Changing Backup CPUs and Dump Files” (page 96).
In case of an internal or fatal error, the PATHMON process generates an error dump and writes
it to a file. You might specify a name for the dump file. For example, this command directs the
PATHMON process to write error information to a file named PMDUMP:
= SET PATHMON DUMP ON (FILE PMDUMP)
The PATHMON process writes the information in the data stack to PMDUMP.
If you request your HP representative’s help in analyzing a problem, the representative will likely
require a DUMP file. HP recommends that DUMP option must be set to ON for production systems.
Specifying the START Command
After you have started the PATHMON process and PATHCOM and configured global parameters,
you can start your PATHMON environment.
