Configuring Objects in a PATHMON Environment

Defining Attributes for Guardian and OSS Servers
If the server process stops under normal circumstances, for example, in response
to a STOP command, the PATHMON process does not attempt to restart it.
•
The CPUS attribute specifies the CPUs on which server processes of this server
class will run.
You can specify either a list of paired (primary and backup) CPUs or a list of single
CPUS.
If you specify single CPUs and a processor is down, the PATHMON process
chooses the next processor in the list.
When you specify a processor pair for a Guardian server, the PATHMON process
creates an extra parameter called BACKUPCPU to hold the number of the
processor specified as a backup. This parameter is passed to the server as part of
the PARAM message. As it creates the server processes, the PATHMON process
uses the primary CPUs in the order specified. If a processor is down, the
PATHMON process uses the backup processor as an alternate processor and
passes the primary processor number as the backup processor parameter.
•
CREATEDELAY specifies the maximum amount of time LINKMON process, ACS
subsystem processes, or TCP process must wait to use an established link to a
server class before the PATHMON process starts another server process.
•
DELETEDELAY specifies the maximum amount of time a link between LINKMON,
ACS subsystem processes, or TCP process and a dynamic server process can
remain idle before the LINKMON, ACS subsystem processes, or TCP process
automatically returns the link to the dynamic server.
The CREATEDELAY and DELETEDELAY attributes have the potential to
dramatically impact system performance. See Configuring Links for Optimum
Performance.
•
DEFINE assigns a DEFINE definition as part of a server class definition. You can
use DEFINEs to specify the default volume and subvolume and to specify files
used by the server.
•
MAXSERVERS specifies the maximum number of server processes in this server
class that can be run simultaneously.
•
MAXLINKS specifies the maximum number of links to a server process from all
TCPs and LINKMON processes.
•
NUMSTATIC specifies the maximum number of static server processes allowed
within this server class. Static server processes are those that start in response to
the START SERVER command.
For a complete description of all the SET SERVER attributes, see Section 12,
SERVER Commands.
