-## Oracle SQL Developer
+## Oracle graphical clients
 
 The Oracle integration works only in the authenticated proxy mode. Start a local proxy for connections to your Oracle database by using the command below:
+
 ```
-tsh proxy db --tunnel --port 1521 --db-user=<user> --db-name=<db-name> oracle
+> tsh proxy db --tunnel --port 11555 --db-user=<user> --db-name=<db-name> oracle
+
+Started authenticated tunnel for the Oracle database "oracle" in cluster "teleport.example.com" on 127.0.0.1:11555.
 ```
 
 <Notice type="tip">
-This command uses the local port 1521, but you can choose any port, or let
-`tsh` pick a local port at random if you omit the `--port` flag.
-You should specify a port to avoid the need to reconfigure your GUI client again
-later.
+The command above uses the local port 11555, but you can choose any available port. Leaving `--port` empty will cause `tsh` to pick a random one.
+</Notice>
+
+The local proxy supports TCP and TCPS modes. Different clients prefer different modes.
+
+TCP:
+- requires no username or password
+- generally easier to configure
+
+TCPS:
+- requires no username or password
+- depends on automatically created wallet
+- uses JDBC URL for configuration
+
+<Notice type="warning">
+Teleport versions earlier than 17.2.0 support only a limited range of clients and only offer TCPS mode. `tsh` will automatically detect this situation and warn the user. We recommend updating to the latest version of Teleport to access full client support and additional connection options.
 </Notice>
 
+### Oracle SQL Developer (standalone)
+
 In "Connections" click the "+" button for a new database connection:
 
-![Oracle SQL Developer Add Database Connection](../../img/database-access/guides/oracle/oracle-sql-developer-add-database.png)
+![Oracle SQL Developer Add Database Connection](../../img/database-access/guides/oracle/sql-developer-standalone-add-database.png)
 
 Next, set the name and username from the `--db-user` parameter. Set connection type to "Custom JDBC" and 
 set the "Custom JDBC URL" from the `tsh proxy db` command.
