About six months ago, when I was in the OUGN Spring Conference, someone asked me how they can let developers access to performance tuning pages on Enterprise Manager Cloud Control 13c. He said that they granted full administrator privileges to the developers so they could access the performance page but it’s not acceptable. He also mentioned that they didn’t need to grant full administration privilege to the developers’ EM users while they were using EM12c.
Unfortunately I forgot to examine the situation until I saw a similar question on OTN (Oracle Community) forum on Friday. The forum reader has exactly the same problem. The database user was already granted required privileges but the EM administrator see the menu items related with “performance tools” are grayed out.
