Friends, Anyone here had issue with this event. A scheduled job (dbms_job) , which is calling a purge Stored Proc is found waiting on this event for a long time - causing some of the sessions wait on Enq TX-Row lock contention. Did not get any hits (p1=p2=p3=0). 10.1.0.5 on RH Linux - 2.4.21-40.ELhugemem #1 SMP Wondering if the masters can shed some light on what this does....... Regards, Ravi.
