Oracle 11g: Grid Control
Grid Control Components -
Important notes to remember
The following are the Oracle Enterprise manager Grid Control components:
1-
Oracle Management Repository
(OMR):
It is a container. It is a collection of schema objects within an Oracle
database. It contains SYSMAN's schema objects. The OMR database listener
monitors port 1521 by default for any incoming connection requests.
2-
Oracle Management Service
(OMS):
It receives information from
OMA
and passes them to
OMR.
It provides the Grid Control console Web pages from information within
the OMR. It includes Oracle HTTP Server (OHS), Oracle Application Server
containers for J2EE (OC4J), and OracleAS Web Cache. OracleAS Web Cache
is configured to listen on port
7777
and OHS listens on port
7778
for connection by default.
3-
Oracle Management Agent
(OMA):
You need one
OMA
for each host server. It must be in its own ORACLE_HOME. It collects
information about target availability, configuration, and performance
and passes that information to
OMS.
In most installation, the OHS listens to OMA traffic on port
4889
by default.
To access the Grid Control console
You use the following URL from Web browser.
(http://<oms host>.<domain>:<port>/em)
For example:
http://oracle.iselfschooling.com:7777/em
