The Elink configuration file also contains the following parameters. These parameters check the connectivity

between the front-end Elink and the NonStop Elink.

ALIVECOUNT: The retry count after which the connection is confirmed lost.
ALIVEPROBE: The time interval in seconds after which a heartbeat probe is sent.

For example, Aliveprobe will probe the NonStop Hosts every X seconds and will declare a host as unavailable if

Y consecutive probes are not acknowledged.
Once Elink starts, the OVNM SPI will register itself to the Elink process as a recipient of a Service. The Elink on

the NonStop Server listens and does not initiate poll’s to remote clients on startup. Registrations for the services

will have to be requested by remote clients.
The NonStop TCPIP stack maintains the ‘keep alive’ timers that can be used in addition to the Elink configuration

files to quickly identify Dead Connections to the remote Clients. It cannot re-establish the whole connection to the

remote client but it can monitor and notify immediately if the connection fails.

NOTE:

For details on how to configure SNMP Adapter, refer to the OVNM SNMP Adapter Guide.
