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 0—3600
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.

addp-timeout

Default Value: 0 (zero)
Valid Values: Any positive integer from 0—3600
Changes Take Effect: Immediately

Specifies the time interval that this T-Server waits for a response from another 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.

addp-trace

Default Value: off
Valid Values:

off, false, no	No trace (default).
local, on, true, yes	Trace on this T-Server side only.
remote	Trace on the redundant T-Server side only.
full, both	Full trace (on both sides).

Changes Take Effect: Immediately

Specifies whether addp messages are traced in a log file, to what level the trace is performed, and in which direction. This option applies only if the protocol option is set to addp.

protocol

Default Value: default
Valid Values:

default	The feature is not active.
addp	Activates the Advanced Disconnect Detection Protocol.

Changes Take Effect: When the next connection is established.

Specifies the name of the method used to detect connection failures. If you specify the addp value, you must also specify a value for the addp-timeout, addp-remote-timeout, and addp-trace options.

sync-reconnect-tout

Default Value: 20 seconds
Valid Values: See, Timeout Value Format.
Changes Take Effect: Immediately
Specifies the time interval after which the backup T-Server attempts to reconnect to the primary server (for a synchronized link).
