MSGMON
These states and their transitions are described in detail in Section 8, SCF Commands
for SNETMON and the ServerNet Cluster Subsystem.
MSGMON
MSGMON is a monitor process that resides in each processor of a server and
executes functions required by the message system. MSGMON is a helper for
SNETMON. MSGMON handles communications between SNETMON and individual
processors. MSGMON also logs events from and generates events on behalf of the
message system. MSGMON was created to relieve the system monitor subsystem.
MSGMON is a persistent process. Once it is started, it terminates only in the event of
an internal failure or a termination message from the persistence monitor, $ZPM.
MSGMON is not a process pair.
The following list summarizes information about MSGMON:
You add the message monitor (MSGMON) process as a generic process using the
SCF Kernel subsystem ADD PROCESS command. This is described in Section 3,
Installing and Configuring a ServerNet Cluster. See the SCF Reference Manual for the
Kernel Subsystem for complete command syntax for the ADD PROCESS command.
As an alternative, you can use the ZPMCONF macro to automate the process of
adding MSGMON, SANMAN, and SNETMON to the system-configuration database.
For a description of the macro, refer to Appendix E, TACL Macro for Configuring
MSGMON, SANMAN, and SNETMON.
Once created, MSGMON is started by the persistence manager (and restarted as
necessary). MSGMON can be stopped with an SCF ABORT PROCESS command or
as a result of an internal failure.
Note. MSGMON is compatible only with G06.09 and later RVUs.
