SET NODE
You can override the execution priority of processes by using the SET SERVER PRI
and SET TCP PRI statements.
If you omit this attribute, the base priority value of the logical node is the priority at
which the PXMCFG process ran when it created the SuperCTL file. The same offset
values are used.
ROLE { CLIENT | SERVER }
specifies whether this NODE object defines resources for requester processes or
service processes. This attribute is required.
CLIENT
indicates this NODE object defines resources to be used by TCP processes and
the broker process for client processes; PATHMON and LCS processes are
created to control server processes.
SERVER
indicates this NODE object defines resources to be used by server classes and
the process broker for server process management and load balancing.
SYSTEM \physical-node-name
specifies the physical name of a local or remote Compaq system containing the
CPUs defined for the NODE object. system-name must begin with a backslash
(\) followed by one to seven alphanumeric characters, the first character must be a
letter.
If you omit this attribute, the name defaults to the system in which the PXMCFG
process is running.
Considerations
•
If you repeat a SET NODE statement with a different attribute value than the one
entered with an earlier SET NODE statement, PXMCFG uses the last value entered
for the NODE attribute.
•
Two or more NODE objects can use the same set of CPUs. For example, to use the
same resources for both client and server processing, define two NODE objects: one
defined as ROLE CLIENT and one defined as ROLE SERVER, each having the
same CPU and SYSTEM attributes.
Link Control Service (LCS) NODE object priority minus 3
TCP NODE object priority minus 5
Server Process NODE object priority minus 10
