event_receive

Use

Use this DBM command to fetch an event that has been triggered.

Repeat this DBM command to fetch additional events. The events are fetched in the chronological order in which they were triggered, the oldest events are fetched first.

The first time you execute one of the DBM commands event_wait, event_receive or event_available, an event session is generated within the Database Manager session. Events that are triggered from this time on are collected and can be dealt with within the event session.

If no event was triggered, you get an error message for the DBM command event_receive.

Prerequisites

You have the DBInfoRead server permission.
The FloatingServiceTasks and PreservedEventTasks database parameters are configured large enough (see: Database Administration, Support Database Parameters).
