I have the same issue. It happens when a batch job kicks in.
They need another index on the table, but refuse to put it there and I am
not allowed to. They are doing full table scans of a 100 gig table. Your
first task is to figure out what is happening when you get the alert. Look
for a pattern, then you know what to look at. Throwing hardware at a
problem only works for so long. Fixing the code always works.
In this situation the solution is simple from the DBA point of view;
instructing the monitoring SW to ignore this alert if at all possible.
I sometimes have difficulty understanding why some folks would prefer to
let there database be slow and struggle with what should be a
straightforward query.
