I manually added one host with oracle database instance into EM successfully, but I can't add the database instance into em12c as target for monitoring.
when I add database from selected host, the Em12c can't discover database instance on that host.
even, I tried auto discovery, EM12c still can't find the database instance on that host. The database and listener are up and running well.
so I am not sure where I missed. please suggest. Appreciate any comments from you.
EM12c version: 22.214.171.124.0
os: Linux 4

I suggest reviewing support note "Understanding Database Discovery in Enterprise Manager 12cCloud Control [ID 1400463.1]". Particularly, take a look at "Has the database been discovered?" section item #3 which basically says to make sure oratab is correct and is accessible by the agent owner.
Let us know if this does not help,
