NO_DATA_WAIT2 Parameter

The number of seconds that PowerExchange Condense waits after it reaches the end-of-log to receive more data.

This parameter sets the Consumer API (CAPI) interface timeout value, which appears in message PWX-09967.

NO_DATA_WAIT2={seconds|600}

For the seconds variable, enter any number greater than 0.

The z/OS Installation Assistant enters 60 for this parameter in the ECCR configuration member unless you specify another value. If this parameter is not defined, the default of 600 is used.

The completion of a condense cycle occurs when the number of seconds specified in the NO_DATA_WAIT2 parameter expires and PowerExchange Condense has not received any data from the PowerExchange Logger.

The optimal value for the parameter varies according to change data activity on the system:

If you set the parameter too low, the Condense operation might end prematurely causing a delay in capturing all available changes to a condense file so they can be extracted.

If you set the parameter too low and the PowerExchange Logger encounters a large unit of work for a source that is not being condensed, the condense operation might also end prematurely because no data is being returned.

If you set the parameter too high, an individual condense operation might never end.
