What is default database listener port number

Running emca script requested for database listener port number. Where do I get this information from.

If the port number is not specified in listener.ora,
you may get different values with 10gR1 such as 1509,
1525, 1525 or 1531 (on Windows XP SP2).
I guess this depends also on whether the TCP/IP port
1521 is really released or notI have seen what you have described above when port 1521 was in use by another process. If the port is not in use, I have not seen any thing other then 1521 assigned when the listener was created either during installation or afterwards using Net Assistant.

How to change the listener port number on a standby database

i want to change the listener port number from 1525 to 1545, which is running on a standby database.
i did the following steps and got some error.
1. i stop listener and modfy listener.ora
2. i login in standby DB and issue 'alter system set local_listener='(address=(pro=tcp)(host=10.10.10.10)(port=1545))';'
3. i login in dg broker and issue 'edit database 's1' set property 'LocalListenerAddress'='(address=(pro=tcp)(host=10.10.10.10)(port=1545))';' and a error coming out ORA-16703: cannot set the property while the database is enabled
4. then i disable database
DGMGRL> disable database 'ssmscs';
5. DGMGRL> edit database 's1' set property 'LocalListenerAddress'='(address=(pro=tcp)(host=10.10.10.10)(port=1545))';
Error: ORA-16541: site is not enabled
Configuration details cannot be determined by DGMGRL
what can i do ? can anybody help me out? thanks in advance.

Hi
You have to edit the following files in $ORACLE_HOME/network/admin or $TNS_ADMIN/ :
In your listener.ora on your standby
MQ_LIST =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = superman.dk)*(PORT = 1524))*
TNSNAMES.ORA (on your primary and standby)
MQ_LIST =
(DESCRIPTION =
(ADDRESS = (COMMUNITY = tcp.world)(PROTOCOL = TCP)(Host = superman.dk)*(PORT = 1524))*
(CONNECT_DATA = (SID = MQ_LIST))
after that do
lsnrctl reload

Select Listener Port Number from which_table?

I'm writing a SQL script that, among other things, disconnects from Oracle and then reconnects to the same instance as a different user. I'm able to query v$database and v$instance to get most of the information I need (host, service name, etc) for the reconnect part. The only part I'm missing is the listener port number. I could hard code it to 1521, but that isn't very flexible. Currently, I'm prompting the user (which is normally me) for the listener port number in the SQL script, but that just seems a little bit lame. So my question is this: is there a view or table somewhere in the sys schema that I could use to view the listener configuration? I'm mostly working with 10gR2+ databases.

That is possible, but it needs to be a standard Oracle configuration if the script is to remain generic and portable. The script is actually working fine as-is. I was just trying to go the extra mile and determine the port number automatically. I could also prompt for a TNSNames entry as suggested by others, but I don't always have an entry defined for all of the Oracle instances in my company on every workstation that I work from.
Here is the script for anyone that is interested. It started out as a script that I found online, but the original did not work with 11g case-sensitive passwords and it only worked for local connections on the server.
Description:
Allows a DBA user to impersonate another user (without knowing the user's password).
Similar in function to using the SU command in Unix/Linux.
Note:
This script temporarily changes the impersonated user's password and may cause other
connection attempts by that user to fail during the moment that the temporary password is in effect.

WHERE name = UPPER('&username');

ALTER USER &username IDENTIFIED BY TempPass;
-- Use the temporary password to connect to the database as the user.
CONNECT &username/TempPass@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=&hostname)(PORT=&listenerport))(CONNECT_DATA=(UR=A)(SID=&servicename)));
-- Reset the user's password to the original value using the original password hash(s).
ALTER USER &username IDENTIFIED BY VALUES '&password_hash';
SHOW USER
UNDEFINE username
UNDEFINE password_hash
UNDEFINE hostname
UNDEFINE servicename
UNDEFINE listenerport
WHENEVER SQLERROR CONTINUE
SET VERIFY ONAnd by so doing you just kicked the user's password expiration on down the road, negating the benefit of havng a password expiration.
Also, you locked out the legitimate user of this account, until such time as you reset it back to the original. And in the mean time, if this happens to be an account used by some automated process, that process doesn't know the new "temporary" password and runs a risk of locking the account from too many invalid connection attempts. Try to become SYSMAN or DBSNMP from this, and you will very quickly kill OEM.
This has "bad idea" written all over it. What problem is it supposed to be be solving?

Changing the listener port number in a cluster environment

Hello,
I have an Oracle 10g database on a Windows cluster environment with Oracle Fail safe. I am trying to change the default listener port number - these are the steps I have done to change the port number:
1) Take the listener offline via Oracle Fail safe
2) stop the original listener from the command line
3) change the port number in the listener.ora file & save
4) start the original listener
5) bring the listener online in Fail safe
6) register the listener in the database with ALTER SYSTEM SET LOCAL_LISTENER....
After all this, when i check the status of the listener via lsnrctl, i see that the new port number is used, however in the Fail safe administrator, I still see the default port 1521. How do I go about changing the port number so that Fail safe also registers the change?

I did troubleshooting to verify the group, but this just changed the port number back to the default in the listener.ora & tnsnames.ora.
So I did all the steps again to change the port number from the default to another - via lsnrctl status, i see that the new port number is being used, I can also log in to the database via Toad using the new port number, in v$parameter i see that the local_listener is registered on the new port number....only under the Fail Safe manager, the port number (under listener parameter) has not changed....it still shows the default port number. Anyone know how to change this???

Changing the Listener Port Number

Hi RACers,
I need to change the TNS listener port number from the default of 1521 (don't ask!).
I'm on Solaris10/Oracle10g 10.2.0.3 using a 2 node cluster.
I've tried editing the relevant files, bouncing everything and re-starting CRS, but that doesn't work. I tried using Netca to delete the listener and re-create it with a different port number and that didn't work either. The instances did not re-register despite having their local_listener parameter changes.
Obviously I'm doing something wrong, but don't know what. Any ideas or do you know where a procedure to do this is documented?
Thanks in advance.

My posting was not aimed at the OP at all.. not his fault that Oracle insists on using a TCP port that's NOT registered for Oracle use.
It is all Oracle's fault that port 1521 is used instead of 1527.
As for what Oracle books say.. bahumbug. Means nothing ito playing by the same networking rules as everyone else.
Port 1527 is what is registered for and by Oracle as use for Oracle tcp traffic. Not fricken port 1521!
And why is this a problem?
If you're in the network business and deal with everything and anything from network analysis and management to rewriting ToS bytes for proper DiffServ application.. then it is very frustrating to find a major company like Oracle ignoring the networking rules.
I read that as Oracle telling us "screw you".

Listener port number

hi,
what is the range of port number of listener in 10g and 11g.
in google it has show only default port number.
thank you

user8647245 wrote:
what is the range of port number of listener in 10g and 11g.Default Listener port is 1521. Registered port for the Oracle Listener with IANA (Internet Assigned Numbers Authority) is 1527 and not 1521.
You can however, in theory, use any port. In practice though, it is not that simple. And can be kind of stupid not to use the default or registered ports.
Ports 0 to 1023 are well known ports. These should never be used by any other applications like the Listener. On many kernels, only a root process can open a well known port.
Ports 1024 through 49151 are (IANA) registered ports. See RFC4340 for the registration process details. And this is where the Oracle Listener is registered as port 1527 - despite Oracle for many years using 1521 instead.
Generally speaking, keep to the default or use the the registered port. Do not arbitrarily change port numbers.
Ports 49152 through 65535 are private or dynamic ports. You should not ever use a port in this range as a listening end point for an application.
Okay, so why use specific ports for specific applications?
It comes down to network management and network performance.
Use arbitrary ports, and you mess sophisticated network designs horrible around. You can cause a negative network impact for your application due to how QoS (quality of service) are implemented. You can run into firewalls. You are not supportting the network folk in managing the underlying network infrastructure properly, enabling them to support your network application as you expect it to be supported.
So do NOT simply change the Oracle Listener port number. And no - changing it does not "improve" security either.

Database - Listener Ports -- Data transfer

Hi,
If there are two databases running on the server, Is it opt to configure unique listener port for the two databases? and what happens if a unique listener port configured?
Thanks

Edited by: KSG on Oct 16, 2011 11:53 PM
Hi Jgarry/Hemant
For client-server data transfer.
I understand like
First, the client send the request to the db server, the listener listens the connection and creates a database server process to handle the request (may be a query..
I just want to understand how the processed data information passes to the client.. i meant.. what are the ports involded to transfer the data back from db server to the client?
From Jgarry, I understand the data flow actually happens through a seperate data port (say it may be any port 1599 or someting).. So Do all the further traffic happens between client-server or server-client uses the same Data-port?
Im trying to understand the architectural flow of connectivity between clien-server and vice-versa. which will help to understand better.
My concern is..
we are establishing connectivity from client through TNS names. The server listenes the connectivity and creates a server session to execute the connectivity. Simply like.. a request made from client to database to listen service_name 'orcl', host=abc.com protocol=TCP port=1521. which is listen on the server side and the server recoganize the connectivity...
Here I'm trying to understand.. once the connectivity is established then there is no need of listener anymore. Even we can stop the listener. How the TCP portocol in the Oracle Net is going to establish the data flow between the servers (how the sequence of request and response happens).
If the TCP network layer is used to interact between the servers then how the data flows between the servers; like is it uses a seperate port number to send/receive the data.
Thanks
KSG
Thanks in advance

)Here I have a single listener, where port 1521 is configured to two database. Is the configuration perfectly ok?.
Yes,these are right
How the client gets actual data transfer from both of these databases?
Clients wil connect using bank2 or bank1 descriptor and will connect bank1 or bank2 services which registered in your listener,You can see that using lsnrctl services command
Ex: If the client connets to the server 10.93.10.40, which ports are used to transfer data from database server to client server?
There used 1521 port to connecting .

MDB and Database - Listener port stops working

Hi,
I have created an MDB which does the following when a message is received from the queue.
1. Store message in database
2. do some processing
At step 1, if there is any issue with the database connection (e.g. database is not available etc), I rollback transaction. My idea is to leave the message on queue for now and retry it again after some time unless the database is back again. "Maximum retries" of the listener port is set to N but since there is no retry interval available, all N retries are done in a flash and my listener port stops working. I cannot use backout mechanism as I have to wait for the database to be back again. What are my options?

a simple JDBC rollback won't do it.

Forms Listener port number as a service!!!

is installed as a service? I tried port=???? but it ignores it
and default back to 9999...

Hi Patrick
Try this on your command prompt
ff50srv32 port=5555
You can assign any port. If you don't then it will take the
default port.
Hope this will help you.

The below format:
TCP 0.0.0.0:1521 0.0.0.0:0 LISTENINGThis endpoint, +0.0.0.0+, listens on port 1521 on all IP addresses of that platform. Including any new dynamically created IPs. Including localhost. The socket parameter is called INADDR_ANY - lots of info available on it (use your favourite search engine).
To bind an Oracle listener to a specific IP, use that specific IP address (dotted format). Do not use the hostname, as the listener by default interprets it as an INADDR_ANY option.
As for not wanting to use localhost.. why not? What are the reasons for this? It cannot be a network security issue.
