The Topology Display subsystem consists of the following Tivoli NetView for z/OS components:
Relationships are reported between Topology Display subsystem components and workstation servers.
Tasks are provided that allow you to:
The following monitors are provided to measure availability and resource utilization of the Topology Display subsystem components:
Each monitor supports the following tasks:
None
None
Reports on the connection between CNMTAMEL and the workstation data server. This monitor is mapped to the IP NETCONV and LU6.2 NETCONV relationships.
Reports on the connections between CNMTAMEL and GMFHS. The monitor is mapped to the Tivoli NetView PPI relationship.
CNMTAMEL uses this relationship to send and receive data to and from the workstation data server. The connection uses the IP transport.
Note: If the NETCONV session was being used to transport the instrumentation data then the connection will not be removed. However, all the components reported on the session will be changed to the UNKNOWN state.
CNMTAMEL uses this relationship to send and receive data to and from the workstation data server. The connection uses the SNA LU6.2 transport.
The connection is removed when the NETCONV session is stopped.
Note: If the NETCONV session was being used to transport the instrumentation data then the connection will not be removed. However, all the components reported on the session will be changed to the UNKNOWN state.
CNMTAMEL uses this relationship to send and receive data to and from GMFHS.
Select this task to warm start RODM.
Select this task to stop RODM.
Select this task to cold start RODM. RODM will be started using the options type=coldforc,init=ekglislm. To change the options, modify the Tivoli NetView for z/OS CLIST CNMETDTK.
After cold starting RODM, you will need to restart GMFHS.
None
None
In this relationship the manager component uses RODM to store and retrieve data.
Select this task to start GMFHS.
Select this task to stop GMFHS.
Select this task to retrieve status and queue depth for all the GMFHS subcomponents.
Reports the number of buffers queued to the IPC subtask.
Reports the number of buffers queued to the View Manager subtask.
Reports the number of buffers queued to the View Status Manager subtask.
In this relationship, the manager component uses RODM to store and retrieve data.
Select this task to start the SNA topology manager.
Select this task to stop the SNA topology manager.
None
None
In this relationship, the SNA topology manager uses RODM to store and retrieve data.
None
None
None
In this relationship, the RODMMGR uses RODM to store and retrieve data.
Select this task to query the current state of the selected component. If GMFHS is not active, Query State will always return DOWN for the RODM component, SNA topology manager component, or any other managers, such as MSM.
Select this task to modify the polling interval associated with the heartbeat monitor for the selected component.
This task retrieves the relationship instances to and from the selected component.
Select this task to query thresholds for all monitors associated with the selected component.
Select this task to query the polling intervals associated with all monitors defined for the selected component.
Reports whether the component is UP or DOWN.
