DRTIMEOUT configuration parameter

Use the DRTIMEOUT configuration parameter to specify the length of time, in seconds, that a database server in a high-availability data-replication pair waits for a transfer acknowledgment from the other database server in the pair. This parameter applies only to high-availability data-replication pairs.

After you edit your onconfig file and restart the database server.
When you reset the value dynamically in your onconfig file by running the onmode -wf command.
When you reset the value in memory by running the onmode -wm command.

Usage

Use the following formula to calculate the value to specify for the DRTIMEOUT configuration parameter:
DRTIMEOUT = wait_time / 4

In this formula, wait_time is the length of time, in seconds, that a database server in a high-availability data-replication pair must wait before the server assumes that a high-availability data-replication failure occurred.

For example, you determine that wait_time for your system is 160 seconds. Use the preceding formula to set DRTIMEOUT as follows:
DRTIMEOUT = 160 seconds / 4 = 40 seconds
