blackout_period

Use this parameter to specify a fixed block of time during which the client cannot run. This parameter is useful for operations, such as database backups, that can only take place when the Client is inactive. For example, if you want to back up the database daily between 1:00 a.m, and 2:30 a.m. daily, define a blockout period from 0:55 to 2:30. The extra 5 minutes ensures that the Client finishes any long transactions before the database backup begins.

If the Client is running when the blackout period starts, the Client automatically stops. If the Client is waiting for an idle host to send it updates when the blackout period starts, the Client resets the TCP/IP connection and aborts the run if it hasn't received any updates after 15 seconds. If you try to run the Client during a blackout period, nothing happens.

When the blackout period ends, the Client automatically restarts (dbutility) or is restarted by the service (DBClient).
