Profile Parameters for the Enqueue Replication Server

enque/enrep/poll_interval

This parameter determines the interval in which the HA software is polled to find out the current failover host. The value 0 means that the entire polling mechanism is deactivated.

Integers/milliseconds

0

enque/enrep/poll_timeout

enque/enrep/inactive_action

This parameter determines which action is executed, if the HA software reports that the replication server is not running on the failover host.

Character string:

sleep or

shutdown

enque/enrep/hafunc_check

Program that is always called if the HA software is polled. The return code of the program specifies whether the replication server is running on the failover host or not. There are different return codes:

• -1: Error; shutdown is triggered

• 0: Replication server is running on the active failover host: Activate or keep active (status active)

• 1- 4: Switch to hold mode (status hold)

• Larger than 4: Replication server is not running on the failover host: Deactivate (status sleep). By using return values the program can control the behavior of the replication server.
