Setting up alerts on OEM 12c

 Hi,

We are in process of setting up more than 1200 DB alerts .My question are :-

 

 1)  Is there a List of alerts or documentation which we can refer and choose which alerts will be good for us and which are not.

2)      How can we test and verify all the alerts are working fine on OEM .

 

3)      Is there any documentation for setting minimum and maximum no. of Critical alerts on Exadata . Which alerts are must recommended .

 

4)      As we have Full Exadata Machine and possible extension of more Machines in future , say we have to manage more than 32 nodes on a RAC. Now we have OS Scripts say more than 100’s   we have configured .
