1. Documentation in Tahiti -> Masters Book List -> Administrator’s Guide -> 10 Managing Oracle Enterprise Manager Database Control

2. The first thing we will do is set up Oracle Enterprise Manager Database Control. DBControl is the OEM version that is included with Oracle Database. It’s simple to install and uninstall.

The first is to enable the user DBSNMP and SYSMAN.

ALTER USER DBSNMP IDENTIFIED BY "******";
ALTER USER SYSMAN IDENTIFIED BY "******";
ALTER USER DBSNMP ACCOUNT UNLOCK;
ALTER USER SYSMAN ACCOUNT UNLOCK;

OEM configure Database Control for DB OCM.

emca -config dbcontrol db

Database SID: COM
Listener port number: 1521
Listener ORACLE_HOME []: /u01/app/oracle/product/11.2.0/dbhome_1
Password for SYS user: ******
Password for DBSNMP user: ******
Password for SYSMAN user: ******
Email address for notifications (optional):
Outgoing Mail (SMTP) server for notifications (optional):

3. Once configured can access the console via the following web address -> https://ocm.dbajunior.com:1158/em

4. stopped and lift the console with the following commands.

# Stop DB Control OEM
emctl stop dbconsole

# Start OEM DB Control
emctl start dbconsole

5. Let’s see how the console is uninstalled along with the repository database.

# Desconfiguramos OEM Database Control
# On the same command indicate that the repository (optional) is cleared
emca -deconfig dbcontrol -repos drop db

6. If you use must configure it with a new repository want again. We will do for now, because in the next section we have many years OEM Grid Control, which replaces Database Control.

# Configuring OEM Database Control with a new Repository
emca -config dbcontrol -repos create db
