Refreshing Ipxproto Object Values - HP T9576G06 Management Manual

IPX/SPX Subagent (G-Series)
IPX/SPX Subagent Process Objects
The zisa group, along with the manager application, facilitates managing the subagent
process. The zisa group is a MIB group that contains the following group and two
tables:
The tdmNwSaConfig group supports management of subagent process
attributes, such as process priority and EMS collector process name.
The tdmNwSaAgentNamesTable entries describe SNMP agents with which the
subagent is configured to communicate.
The tdmNwSaIPXPROTONamesTable entries describe IPXPROTO processes
that the subagent is configured to monitor.
Many of the MIB objects in this group and tables have corresponding startup
parameters, so you have two means by which the subagent process can be managed.

Refreshing IPXPROTO Object Values

When the subagent is started, it does not immediately refresh the values of
IPXPROTO objects in its MIB. The values of objects in each of the six tables containing
IPXPROTO process values are refreshed for the first time after startup when the
subagent accesses the table to process an SNMP request:
ipxBasicSysTable
tdmNwInfoTable
tdmNwIPXTable
tdmNwSPXTable
tdmNwNCPTable
tdmNwServerTable
Subsequently, table values are refreshed when a table is accessed only if the number
of minutes associated with the subagent's refresh timer have elapsed since the last
time an object in the table was accessed. For example, if you access a table at 12:15
and the refresh timer interval is set at 10 minutes, the timer stops running at 12:25. If
the table is accessed at 12:30, the table values are refreshed before the request is
processed, and the timer is reset. The table will not be refreshed again until after the
timer stops running and before the table is accessed again.
At startup, you can specify a refresh timer value using the -r startup parameter:
RUN IPXSA /NAME $ZISA, NOWAIT/ -r refresh-interval
The refresh interval is the duration, in minutes, of the refresh timer for each of the six
tables listed above. By default, the refresh interval is 10 minutes.
After startup, you can change the value of tdmNwSaRefreshTimer in the
tdmNwSaConfig group to specify a different interval. Setting the value of this object to
zero causes the subagent to retrieve new data from an IPXPROTO process every time
it receives a request. You can also force data refresh for all the tables on demand by
