So, how to quickly check which ports are indeed in use by OEM?
Easy:
[oracle@greporasrv ~]$ cat $OMS_HOME/install/portlist.ini
Enterprise Manager Upload Http Port=4889
Enterprise Manager Upload Http SSL Port=4903
OHS Http Port=9788
BI Publisher Http Port=9701
Enterprise Manager Central Console Http SSL Port=7802
Node Manager Http SSL Port=7403
BI Publisher Http SSL Port=9803
OHS Http SSL Port=9851
Managed Server Http Port=7202
Oracle Management Agent Port=3872
Enterprise Manager Central Console Http Port=7788
Admin Server Http SSL Port=7102
Managed Server Http SSL Port=7301
Hope it helps!
