14.7.10 Setting the event acquisition start location
The event acquisition start location is set by the -b option of the jcoimdef command. The location is determined as shown in the table below, according to the value specified in the -b option.
Value specified in -b option |
Acquisition start location |
---|---|
-1 |
The event following the last event processed by JP1/IM - Manager |
0 |
Events registered since JP1/IM - Manager started |
1 to 144 |
Events registered within a specified period of time before JP1/IM - Manager started |
The effect of each setting is as follows:
- Organization of this subsection
(1) Acquisition start location when -1 is specified
If you start JP1/IM - Manager with -1 specified in the -b option of the jcoimdef command, the event base service sends the event with the oldest serial number (the event at the location where processing stopped) to JP1/IM - Manager.
(2) Acquisition start location when 0 is specified
If you start JP1/IM - Manager with 0 specified in the -b option of the jcoimdef command, the event base service sends events registered after JP1/IM - Manager startup to JP1/IM - Manager in the order in which they were registered.
If no such events exist, the event base service remains in standby mode until a new event is registered.
(3) Acquisition start location when 1 to 144 is specified
If you start JP1/IM - Manager with any of 1 to 144 specified in the -b option of the jcoimdef command, the event base service sends events to JP1/IM - Manager that were registered within the length of time specified by the -b option before JP1/IM - Manager started.
In this case, the acquisition start location is the time at which JP1/IM - Manager started, less the time specified by the -b option of the jcoimdef command.
