Accessing Grid Control
Versus Database Control
Access to Enterprise Manager is different depending on
whether you use Grid Control or Database Control.
Example:
DB Host
Grid Control URL
Database Control URL
dbhost1
http://<oms host>:7777/em
http://dbhost1:1158/em
dbhost2
http://<oms host>:7777/em
http://dbhost2:1158/em
dbhost3
http://<oms host>:7777/em
http://dbhost3:1158/em
http://dbhost3:1159/em
