backup-sync Section

The backup-synchronization section contains the configuration options that are used to support a high-availability (HA) hot standby (redundancy type) configuration.

Warning: These options apply only to T-Servers that support the hot standby redundancy type.

addp-remote-timeout

Default Value: 0 (zero)
Valid Values: Any positive integer from 03600
Changes Take Effect: Immediately

Specifies the time interval that the redundant T-Server waits for a response from this T-Server after sending a polling signal. The default value of 0 (zero) disables the functionality of this option. To establish an appropriate timeout, specify a value other than the default. This option applies only if the protocol option is set to addp.
