Hey all, In GC 10.2.0.3.0 I've had a notification failure that went unnoticed. For some unknown reason, the SYSMAN AQ tables were not being completely flushed. The result was that sometimes I got notifications from Grid Control and sometimes I didn't. So, I need to write yet another monitoring tool to make sure the monitoring tool works. I have one to check GC jobs, one to check OMS/Agent/Everything logs, and now one to check the notification queue (which I may combine with one of the former). Which begs the question: what do *you* have to look after in your GC installation? Rich -- //www.freelists.org/webpage/oracle-l
