adjustment (positive or negative) will be added to each of the pulse

timestamps the Consumer is responsible for setting.

When PULSEAUTOADJ is enabled this parameter is configured

automatically.

The value for the PULSECLOCKADJ parameter is specified in

microseconds (i.e.,i.e., 1/1,000,000th second intervals). The default value

is 0, meaning no time adjustments are made.

The valid range is -2147483647 to 2147483647, i.e.,i.e., about 2147

seconds in either direction.

Note: That a plus sign should not be specified for positive numbers. This

parameter can be altered at any time.

This parameter is used to define if a Consumer is to automatically

compute the clock drift between the sending and receiving systems and

adjust a server’s “pulse” timestamps accordingly. By default, this

parameter is set to ON. Set it to OFF to disable the feature.

Note: The pulse clock-timing adjustment message will only be output to

EMS if the adjustment exceeded 100 milliseconds and the pulse

feature is configured.

3.990 30 1 1209600 Yes

Client Server Extended Open Target

This parameter defines a threshold for the replication latency in seconds

(replication latency is defined as the time from when the source pulse I/O

occurred to when the target pulse I/O occurred). Since pulses follow the

same path in the replication engine as the application data, this is an

accurate representation of the time to replicate the application events.

The default is 30 seconds. The valid range is 1 through 1209600 (14 days

in seconds).
