How High-Availability Data Replication failures are detected, in the chapter on High-Availability Data Replication in the IBM Informix Administrator's Guide

DRTIMEOUT applies only to high-availability data-replication pairs. This value specifies 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. Use the following formula to calculate DRTIMEOUT:

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 it assumes that a high-availability data-replication failure occurred.

For example, suppose 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
