In-Depth Information
Here the image shows a basic command line is issued to create a new repository and
configure the DB Control Console (
A
). As there are more parameters required to
configure the console EMCA prompts for additional parameters; it asks the user to
provide the listener port (
B
), which DBAs typically configure to be
1521
, which is the
default TNS Listener port. Then it asks for three passwords; the
SYS
(
C
),
DBSNMP
(
D
), and
SYSMAN
(
E
) passwords. In the image it looks like the EMCA is asking
twice for the SYSMAN password, this is actually a harmless display bug that can be
safely ignored.
Make sure the DBSNMP account is unlocked and it has
a non expired valid password.
The EMCA feeds back the provided values (excluding the passwords) to the user
and waits for the user to confirm them (
G
). If everything is correct then the EMCA
proceeds with the configuration. The user should pay attention to the process
progress and confirm that it successfully reaches the end. The output is logged to the
directory shown on the screen, and the user must be aware of it, as if there is an error
a summary and a detail log file will be generated.
The path where the EMCA logs the executed actions as well as their outcome is
located at
<Oracle Home>/cfgtools/emca/<Oracle SID>/emca_YYYY-MM-DD_HH-
MI-SS-PM.log
this file will record the progress and main information; it will also
provide the name of a secondary file where further progress details are provided.
The EMCA provides progress information until it reaches the end of the
configuration process, the time it takes to finish the process depends on the I/O
speed as well as the hardware performance in general.
The final step of the setup process shows the URL to access the console (
H
). Take
note of this URL. This shows the EM Port to access the console, and finally (
I
) the
message
FINISHED
EMCA
is displayed; this is the end of the basic setup session.
The next image shows a basic setup session using 11.2.0 (11gR2), basically, the same
command is issued (
A
):
emca -config dbcontrol db -repos create
