You can use sp_modifythreshold to change the name of the procedure associated with the last-chance threshold. You cannot use it to change the amount of free space or the segment name for the last-chance threshold.
sp_modifythreshold requires that you specify the number of free pages associated with the last-chance threshold. Use sp_helpthreshold to determine this value.
The following example displays information about the last-chance threshold, and then specifies a new procedure, sp_new_thresh_proc, to execute when the threshold is crossed:
sp_helpthreshold logsegment
segment name free pages last chance? threshold procedure ------------ ---------- ------------ ------------------- logsegment 40 1 sp_thresholdaction (1 row affected, return status = 0)
sp_modifythreshold mydb, logsegment, 40, sp_new_thresh_proc
