Management Repository has been placed in secure mode wherein Enterprise Manager data will be
encrypted. The encryption key has been placed in the file: /u01/app/oracle/product/11.2.0.3/

will become unusable if this file is lost.

Deconfiguring Database Control
Deconfiguring is as simple as what you did to originally configure. Simply invoke
emca
using the parameter
-deconfig
.
The
-deconfig
option will begin the process of deconfiguring l. Listing 6-16 shows how to deconfigure Database
Control for the current database on the Oracle Database Appliance.
Listing 6-16.
Deconfigure the Database Control
$ cd $ORACLE_HOME/bin
$ ./emca -deconfig dbcontrol db
When the deconfiguration begins, the
emca
utility will ask you for the
ORACLE_SID
value associated with the
Database Control you are deconfiguring. Provide that ORACLE_SID value; then
emca
will ask if you really want to
deconfigure Database Control. This is a confirmation prompt, and an answer is needed. Once the deconfiguration is
complete, the database console will not be usable or accessible for the associated database.
Listing 6-17 shows output from a typical deconfiguration operation.

Why might you wish to deconfigure Database Control? One answer boils down to using Enterprise Manager
instead. When faced with monitoring more than just the single database or a single cluster database, many
organizations begin to look at implementing Oracle Enterprise Manager, a product widely used for monitoring more
than one database in an enterprise environment. By contrast, Database Control is traditionally used for a single
database or a single cluster database within the environment. Thus, the need to manage multiple databases via
Enterprise Manager is one reason you might choose to deconfigure Database Control.
