Specifying Limits
Limits are global values that determine the maximum number of objects of each type that you can
define when you are ready to configure individual objects. For example, suppose that you want
to indicate that your system will permit a maximum of:
5 server classes
25 server processes
5 server STARTUP messages
7 server ASSIGN messages
5 server PARAM messages
To establish these limits, you enter these commands:
= SET PATHWAY MAXSERVERCLASSES 5
= SET PATHWAY MAXSERVERPROCESSES 25
= SET PATHWAY MAXSTARTUPS 5
= SET PATHWAY MAXASSIGNS 7
= SET PATHWAY MAXPARAMS 5
The PATHMON process saves the configuration values that you specify in memory, as shown in
Figure 14 (page 40), until you specify the START command, at which time the PATHMON process
writes the values to the PATHMON configuration file. For the syntax of all SET PATHWAY commands,
including descriptions of all required parameters, see “PATHMON Environment Control Commands”
(page 150).
Figure 14 Specifying PATHMON Environment Limits
By specifying limits, you allow the PATHMON process to reserve the disk space that it needs for
configuration information. Later, when you actually define and add your PATHMON-controlled
objects (described in “Configuring Objects in a PATHMON Environment” (page 51)). The
PATHMON process monitors these limits and ensures that they are not exceeded.
Specifying Node Independence
Using the NODEINDEPENDENT attribute makes unspecified node names for processes and devices
default to the node where the current PATHMON process is running. Using this attribute in your
PATHMON configuration facilitates switching your PATHMON application to another node, either
in the event of failure or as part of a planned migration (for example, in a configuration that
includes Nomadic Disk technology). When the PATHMON process is cool started on the new
node, the unspecified node names resolve to that node, thereby migrating the associated objects.
This command establishes node independence for objects in your PATHMON configuration, unless
a node name is explicitly specified for a given object:
= SET PATHWAY NODEINDEPENDENT ON
