NO_DATA_WAIT2 Parameter

NO_DATA_WAIT2 Parameter

After the NO_DATA_WAIT interval is no longer in effect, the number of seconds that the Datacom table-based ECCR waits after reading the Datacom CDC tables and finding no new change records before doing another read operation.
During a subsequent read operation, if the ECCR finds changes, the NO_DATA_WAIT interval takes effect again. If the ECCR does not find changes, it waits for the NO_DATA_WAIT2 interval and then tries the read again. The ECCR continues to wait for the NO_DATA_WAIT2 interval and retry the read on an ongoing basis, as long as no changes are available.

The z/OS Installation Assistant enters 999 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.
For the
seconds
variable, enter a number of seconds greater than 0.
Default is 600.
During the wait interval, the ECCR waits simultaneously for input from the console.
