prompt> $ORACLE_HOME/bin/lsnrctl stop
ORACLE_HOME is the home directory for your existing database.
If you do not stop the existing listener, the installation will fail.
2. Install the OracleAS Metadata Repository.
See any of the procedures that install an OracleAS Metadata Repository in
Chapter 4, "Installing OracleAS Infrastructure" (for example, Section 4.20,
"Installing OracleAS Infrastructure" or Section 4.21, "Installing OracleAS
Infrastructure Against an Existing Oracle Internet Directory" ).
3. Update the configuration file of the new listener, as necessary. The name of the
listener configuration file is listener.ora, located in the ORACLE_
HOME/network/admin
directory.
a. Check network address entries in the existing listener’s configuration file.
If the existing listener’s configuration file contains only the following network
addresses:
* TCP Port 1521
* IPC key EXTPROC
you do not have to edit the OracleAS Metadata Repository listener’s
configuration file for network addresses.
If the configuration file contains other network addresses, you need to add
them to the OracleAS Metadata Repository listener’s configuration file.
b. Check SID_DESC entries in the existing listener’s configuration file.
If the existing listener’s configuration file contains SID_DESC entries for the
existing database, you need to add these entries to the OracleAS Metadata
Repository listener’s configuration file.
c. Do not start the existing listener (version earlier than 10.1.0.2). Now that the
new listener supports both databases, you do not need to run the existing
listener any more.
2.5.4.1.2 Scenario 2: Existing Listener Uses Port 1521 and Listener Version Is 10.1.0.2 or Later
The existing listener will support both the existing database and the OracleAS
Metadata Repository. The installer will perform this configuration automatically.
The listener can be running during installation.
2.5.4.1.3 Scenario 3: Existing Listener Uses a Port Other Than 1521 You will end up running
two listeners: one for the existing database and one for the OracleAS Metadata
Repository, regardless of the version of the existing listener.
The existing listener can be running during installation, because it is not using port
1521.
2.5.4.2 If Port 1521 Is In Use by Some Other Application
If you have some other application listening on port 1521, you need to reconfigure it to
listen on a different port. If that is not possible, shut it down while you install the
Note: Step c above is very important. You only need to run one
listener (the new listener) to support both databases.
