Listener Port Conversion To Static Port
Mar 2, 2012
For every connection, oracle listener creates a unique dynamic port. Is this can be made static port for all connection? This a query raised in our penetration testing.
Listener log Sample :
02-MAR-2012 17:40:28 * (CONNECT_DATA=(SID=ORCL)(CID=(PROGRAM=)(HOST=__jdbc__)(USER=oracle))) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.1.3.12)(PORT=3773))
02-MAR-2012 17:39:31 * (CONNECT_DATA=(CID=(PROGRAM=)(HOST=__jdbc__)(USER=))(SERVICE_NAME=orcl)) * (ADDRESS=(PROTOCOL=tcp)(HOST=10.1.1.84)(PORT=38192))

I have local development Oracle 9i database in my Windows XP. I see it uses TNS Listener port 1521. For some reason it must be using port 8080 also or in the background because it seems to not let my local web container (Apache Tomcat which uses Port 8080) on the same workstation work when it (TNS Listener) is turned on. how I edit the Listener port number and if I do change the port number what other things do I need to change such as the OEM login settings to the local database

ENV: Oracle 10gR2, RHEL 64bit on ASM (10gR2):
Current listener port is 1521. I have been asked to change it to 10526
I tried changing the port number in the listener.ora file and then restarting the listener but the I start getting "ORA-12541: TNS: no listener" error. If I change it back to 1521 and restart the listener, I am able to connect to the database. What else do I need to do to change the port #? After I change the port and restart, here is what I tried to test: $ sqlplus user/password@sid...ERROR:ORA-12541: no listener Enter user-name: When I rollback the port# change, I am able to login.

i have a listener configured on default port 1521 and i wanted to change it. i did following:-
1. stop the listener through lsnrctl stop
2.change the port number in tnsnames.ora and listener.ora and save both files.
3.now i start the listener as lsnrctl start
4.it started successfully but saying that it cannot register to instance.
5.i connect sqlplus / as sysdba and execute "Alter system register" and "System Altered"
but even then the listener is not registering.

I installed apex and configure the apex listener at port 80 by mistake couldn't pay attention to use port 8080. The installation is complete but the apex is running at URL.... but the login window is invisible on the page. I can just see the name on the tab "Application Express Login" . When i click on the error message at the bottom of the browser, the message says "apex is undefied" line 35.
When I run the server, I get a message "No free port within range 80. How can I change from port 80 to 8080? how to either un-install the listener or change the port 80 to 8080

why the apex listener tries to return on port 7777 and is there any way we can change it?
In our infrastructure we block that port for security reasons. We are using OC4J (10.1.3.5.0).

I need to encrypt network data for some DBs on one server but not for all of them. How can i achieve this?
Is it possible to encrypt conections on one port and not other?
I know i have to use SQLNET.ENCRYPT_SERVER in the sqlnet.ora file, but how can i do that for only on port?

We use shared servers for our application connections... when the database starts and randomly grabs a free port number for the dispatchers, we occasionally run into a port conflict - we also have tuxedo and several other processes that start after the database, that have pre-defined ports assigned. So if the dispatcher grabs port 52452 but say the workstation listener is defined to use that same port - once the WSL starts, we have a conflict.
I know we can pre-assign specific ports to the dispatchers; my concern with doing that is that we currently support roughly 150 customers remotely, all using our standard database configuration; many of these have multiple databases per server - in some cases, up to 10-15 databases. So manually managing specific ports on all of these would be tedious, to say the least... especially if some other third party app comes into play that happens to use one of the ports we selected, and we have to change everyone's ports again.
letting Oracle randomly pick a free port within the defined range.
if we add the known ports that are used in applications that start after the databases (the ones we end up in conflict with) to the /etc/services file - will that prevent the dispatchers from using those ports? Does Oracle search the /etc/services file to find used ports, before it assigns new ones out?
All servers are HP-UX, a mix of PA-RISC based and Integrity. Oracle versions are all 10.2.0.3, with a few at 11.2.0.2. Before anyone suggests it, moving away from shared servers is not an option; our application makes new database connects at every query - so thousands of connects / disconnects every hour; the overhead of spawning a new dedicated connection for every one if these is too great, and significantly slows down the application.

I have two databases on the same oracle 11g install. The first (ORCL) database uses the default port for EM (1158). However, I don't know what the second one uses. I go to the portlist.ini file, but it only has the entry for the default (ORCL) database.

we have a database available in UNIX machine A which can be connected from client in UNIX machine B through port 1521.
If we give ping command from UNIX machine A to B or B to A, 0% packet loss, means connection established properly through firewall in port 1521.
Now we are setup one more UNIX machine C and installed a client here. This machine is available in different group, means if i give ping command from machine C to A, 100% packet loss. But from machine A to C, connection established with 0% packet loss.Because of this, when we tried to connect to a database from client in Machine C to database in Machine A, we got "time out" error.
My query is:
1. Is this because of not opening of port 1521 through firewall?
2. If so, is it enough to open port 1521 through firewall when we connect from machine C to A?
3. Any additional setup is required in firewall apart from opening of ports?
Environment:
Oracle 11.2.0.3
UNIX AIX 5.3/6.1

I want to configure the Email Alert Notification in OEM.
In OEM --> Setup --> Notifications Methods --> I am able to see a provision to enter SMTP Address, but there is no port number.
Due to some security policies, my company has opened only Port Number : 9925 for SMTP and blocked Port number : 25.
When I click on "TEST MAIL SERVERS" button, it gives me a error that :
"Test failed with message : Could not connect to SMTP Host , Port No. 25" .
Now I want to change this port number 25 to 9925.
