The company where work has one database that it is not managed internally, was passed the administration to great multi national with three letters only in the name, the problem is that this database was unavailable in last the two months 3 times and me was requested that raised the following information: in the dates where database was unavailable how much down time of this database had? Detail I do not have access to the alert(sid).ora.

How I obtains this information?
With one it prays for GOD?
Crying?
Cursing the Larry?
Saying with the Boss
that of the one not
to make?
