Hi,

Is there a record that just pauses record processing for a specified

period of time, or some way to pause record processing in the database?

Thank you,

Patrick

Here in KEK, we use a watchDog record described by the following dbd.

menu(watchDogTTYP) {
	choice(watchDogTTYP_Ticks,"Ticks")
	choice(watchDogTTYP_Second,"Second")
}
recordtype(watchDog) {
	include "dbCommon.dbd"
	field(VAL,DBF_LONG) {
		prompt("Result")
		asl(ASL0)
	}
	field(TTYP,DBF_MENU) {
		prompt("Time Type")
		promptgroup(GUI_INPUTS)
		interest(2)
		menu(watchDogTTYP)
	}
	field(DTIM,DBF_DOUBLE) {
		prompt("Delay Time")
		interest(1)
	}
	field(CANL,DBF_UCHAR) {
		prompt("Cancel Watchdog")
		special(SPC_MOD)
		interest(1)
	}
}

When this record is precessed it wait for the time specified in DTIM

field and follow forward link, unless operation is canceled by writing

value to CANL field.

I'm not sure who is the original author of this record, but source code

says it based on the record by Julie Sander and Bob Dalesio. The version

we used now is based on version by Susumu Yoshida.
