Trying to change Oracle listener port 1521 to nodefault port on Oracle RAC

Could somebody please help me in the process of changing teh Oracle listener port 1521 to a non-default port on an Oracle RAC environment. I am total of four instance.
Regards.

Please read carefully about LOCAL_LISTENER parameter, you shouldn't put there just hostname....
Another way to do so - statically register database SID in listener. You should do it in listener.ora file, please read carefully documentation, otherwise you can use netca utility - it could make configuration for you properly.

Problem when I tried to change weblogic listen port from 7001 to 80

HI! I have problem when I tried to change weblogic listen port from 7001 to 80. When I changed from 7001 to 7777 then all works ok! But why not on 80? With apache all works ok on 80 too.
I restart my weblogic server and then I have following errors.

Debuger,
It does not matter which WLS version I am using (although I'm using 10.3, the one that comes with JDev 11g).
The problem is that SOME OTHER PROCESS on your machine is listening on port 80. Guess you need to go to the Microsoft forums to find out how you can tell what that OTHER, NOT WLS process is.

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".

How to change Port 1521 to 1526 on EBS 11.5.10.2

Hi,
I am using EBS 11.5.10.2 and 9i Database. ( Single Node ) , on Linux platform
I want to change port form Port 1521 to 1526 on the Server
Can some please guide me how to do this.
Thanks,

There is a port pool calculator in the Rapid Clone FAQ for 11i. The easiest way to change an existing port pool is to vi $CONTEXT_FILE in both oracle and applmgr environments, globally change the ports, and run adconfig on both database and applications with the applications down. Restart the database and listener when you are done.

Listener Port 1521 Unavailable....

Hi,
I was installing Oracle 8i Enterprise on a Windows NT 4.0 with Service Package 6 platform. The installation goes fine until Oracle tries to detect port 1521. Oracle responds with the Port is already being used by another software.
I checked the ports using Windows utility 'netstat' and did not find port 1521 in use. I tried a whole range of Port numbers, but Oracle responded to each one as already in use. I accepted Port 1521, but Oracle informs that it will not be able for usage until the problem has been resolved.
So now SQLPLUS comes up fine locally, but no Client is able to connect to the Server as the Listener could not be configured.
Why is Oracle seeing these Ports as already in use ? I have minimal software on the machine...NT and now Oracle.
Any Ideas or tools/utilities that may be of help will be greatly appreciated.
Thanks

I figured it out.
It was an NT Networking issues. The TCP/IP component had become corrupted, so I reinstalled NT TCP/IP and reinstalled Oracle
without issues.

Changing of the standard port 1521 and afterward problems with Single Sign

System / Host Environment
Operating System: HP-UX 11i, Existing Oracle RDBMS Vers. 9.2 x, Listener on standard port 1521
9iAS System Architecture: 9iAS Infrastructure and Middle tier (AS Instance) on the same machine
Problem Environment:
-Before and during the installation of 9iAS infrastructure the Listener of the existing Oracle RDBMS was stopped
-The installation of 9iAS Infrastructure (db: IASDB) Version 9.0.2.0 works well
-Afterwards the port 1521 of IASDB changed to 1525. For a detail description of IASB port changing please refer to Doc. ID: 211 929.1 AFTER CHANGE 'IASDB' LISTENER PORT
-The installation of Patch Set 2 (Common Patch 2703110) follows (9iAS is now up to Release 9.0.2.2).
-The Installation of 9iAS Middle tier (AS Instance) Version 9.0.3 follows
Problem description:
-During the installation of 9iAS Middle tier problems with Single Sign On occurs.
The reason of this problems seems a communication problem between the Single Sign On login sequence and the IASDB. After a reset of the port changing (back to the standard port 1521) the installation of 9iAS Middle tier works well.
Through this incorrect and problematic behaviour we have some notes and questions:
-Well at first the description of the port changing in Doc. ID: 211 929.1 seems us incomplete. Some configuration still carry on the standard port 1521 and not the knew value of the port 1525.
-So we want to know all configuration files and parts where we have to change the port value manually ?
-What will happened to the Single Sign On function with this manually port changing. Does Single Sign On works later on correct or have we to change much more ?

Currently, changing the listener port is not supported. It must stay on 1521. I believe this is to be fixed in a latter release (perhaps 9.0.4)

DISPATCHER : avoid change of a default PORT 1521

I have configured DB 10.1.0.3 with SHARED SERVER .
If I connnected to the database (SERVER=SHARED), dispatcher would use
non-default PORT as
"D001" established:5 refused:0 current:4 max:972 state:ready
DISPATCHER <machine: ............., pid: 19839>
(ADDRESS=(PROTOCOL=tcp)(HOST=..............)(PORT=35972))
I use my database behind the firewall in DMZ , so I want to use a default PORT 1521 with my dispatcher D0001.
There was an option "PORT" in a initialization parameter DISPATCHERS in previous DB versions. I cannot use this option in the database release 10.1.0.3.
Help me?

I'm afraid you can't do that, at least with that version.
See http://download-uk.oracle.com/docs/cd/A97329_03/core.902/a92171/concepts.htm#1016370
Here an extract :
The metadata repository is always configured to use port 1521 and has a service name of the form iasdb.host.domain (for the first infrastructure on a host) and iasdbx.host.domain for any subsequent infrastructures on that host). You should never change these values.

Oracle listens on a second randomly selected port

Hello everybody,
Could someone, please, help me to understand what's going on with my oracle 9.2 db running on Linux.
In addition to known and well defined TCP/IP port 1521 listener uses my oracle also starts listening on some other randomly chosen by itself TCP/IP port.
Let's say right now it listens on port 32039 while during the previous restart it listened on 5389 and etc.
Each oracle db restart (I use dbstart / dbshut cycle) gives me a unique line after "netstat -tanp | grep -e LISTEN" execution:
tcp 0 0 0.0.0.0:32039 0.0.0.0:* LISTEN 2793/ora_d000_db891
tcp 0 0 0.0.0.0:1521 0.0.0.0:* LISTEN 2820/tnslsnr
I can stop listener but that random port will be still there... it makes me nervous.
I asked this question at Oracle-Linux forum and one of the linux experts kindly suggested me to rise this issue over here as well after reporting that he has the same strange listening "creature" within his own oracle db box.
Thank you very much for your help
jeff

That is the way Oracle operates.
For dedicated server operations, the initial connection request is done to the listener. The listener 'spawns' a server process for the connection request. That server process finds a new port and the connection request is turned into a full connection on that new port. The listener is then no longer involved with the connection.
The d000_ is the shared server's dispatcher. It gets a port when the database decides a dispatcher is required, and connection requests are then transferred to an available dispatcher. There can be many dispatchers.
In some cases (such as the XML-related service, used since Oracle8i and prevelant in XE) the dispatcher is pinned to a specific port to support a specific service.

How do I change the listener port for APEX on XE

Hi all,
I did a default install of XE onto a Linux box which is my DMZ server. The default port for the listener is 8080, however I have since found that port 8080 is the port for proxy servers and therefore I cannot access APEX on my DMZ site from behind a client's proxy server.
Is there is simple way to change the listener to port 80 for access to APEX.
Many thanks
Bryan

Trying to write a Listener on a CheckBox to change the Model of a ComboBox

I am trying to change the list that appears in a ComboBox dynamically based on if a CheckBox is selected or not. I have multiple CheckBoxes and ComboBoxes being created in a loop based on a variable assigned at creation. Every tutorial i have seen writes out a listener that explicitly defines the checkbox instance but in my case i don't acctually know. My checkboxes are in an array of checkboxes as are the comboboxes as they are being created at runtime. Any help would be much apreciated this issue has been with me for two days now.

here is a snippit of my code in how i was implementing this:
int numButton = 17; //this is for testing only, this variable is set from another class normally
// these variables are defined private elsewhere in the class
JCheckBox PlayerByeCheck[] = new JCheckBox[numButton + 1];
JCheckBox PlayerHomeCheck[] = new JCheckBox[numButton + 1];
boolean PlayerOnBye[] = new boolean[numButton + 1];
for (int i = 1; i <= numButton; i++) {
         PlayerByeCheck[i] = new JCheckBox();
     PlayerHomeCheck[i] = new JCheckBox();
     PlayerOnBye[i] = false;
// more code here for building the gui it is not important for this problem
// code to build the list starts here
for (int i = 1; i <= numButton; i++) {
     ((TableLayout)PlayerRosterPanel.getLayout()).insertRow(1, TableLayout.PREFERRED);
         PlayerByeCheck.setOpaque(false);
     PlayerByeCheck[i].addItemListener(this);
     PlayerByeCheck[i].setName("PlayerByeCheck" + i);
     PlayerRosterPanel.add(PlayerByeCheck[i], new TableLayoutConstraints(2, 1, 2, 1, TableLayoutConstraints.CENTER, TableLayoutConstraints.FULL));
//the comboox that i want to change
//---- PlayerTeamSelect1 ----
     if (PlayerOnBye[i] = true) {
          PlayerTeamSelect[i].setModel(new DefaultComboBoxModel(new String[] {
               "ARI",
               "ATL",
               "BAL",
          "BUF",
     "BYE"
          PlayerTeamSelect[i].setSelectedItem("BYE");
     } else {
          PlayerTeamSelect[i].setModel(new DefaultComboBoxModel(new String[] {
               "ARI",
               "ATL",
               "BAL",
               "BUF",
               "CAR",
          "BYE"
     PlayerTeamSelect[i].setOpaque(false);
     PlayerRosterPanel.add(PlayerTeamSelect[i], new TableLayoutConstraints(4, 1, 4, 1, TableLayoutConstraints.FULL, TableLayoutConstraints.FULL));
//more gui code here method gets closed
//Item Action Listener starts here this is where i am having the problem
public void itemStateChanged(ItemEvent e) {
     Object source = e.getItem();
     if (source == PlayerByeCheck[1])
     int select = e.getStateChange();
          if (select == ItemEvent.SELECTED)
          PlayerOnBye[1] = true;
PlayerRosterPanel.repaint();
//repaint the window i think can't get the listener to work to see if this is the right way to do this
//i doubt it is
I have tried several different ways to write the listener, the example in the code above is following the java swing tutorial by explicitly defining the checkbox. I have tried to write the listener as i am creating the checkbox, which doesn't seem to work or i am wrting it wrong, which is entirely possible. Once the listener sets the value i think it should repaint the screen but i am sure that that is wrong right now as well. As my hunch is the repaint will reset the checkbox to DESELCTED the default value. I will come to that issue once i figure out how to get the listener working. Ideally i want to be able to set the listener for the checkboxes regardless as to how many there are. As stated above i am generating a list of checkboxes, comboboxes and other fields based on a variable that is defined in one of my objects. If the user selects checkbox 3 than combobox 3 should be changed, and the others should not. if the user selects all the checkboxes than all the comboboxes change.
thanks for any help. Still plugging along on it trying to figure this one out.

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

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

IOS Zone firewall (ZFW) & changing SSH listening port

I'll have to check into the deetails again but I recall there being a way to change the listening port for SSH. Not only do you have to configure SSH itself to listen on a new port but I think there was something about making the inbound interface part of a rotary group or something.
Anyway, my question is more about how the zone firewall reacts to this. If I have inspect set for SSH, (or pass) and yet change the default port for it, does the IOS still know to take the configured action on the protocol? I'll try to test this myself once I have an opportunity but may not be able to for several days, plus if anybody has anything further to add regarding any other implications this port change mgiht have, please share
Thanks!

Hi Julio,
You are ever helpful sir Howver, things are not making sense.
Ok so to take it from the top. So far I have done the following:
Router(config)#ip ssh port 2340 rotary 1
Then:
Router(config)#line vty 0 123 (123 = max # of vty lines, my actual # is different)
Router(config-line)#rotary 1
This of course does not make SSH on port 2340 work from the Internet zone to Self as I have not yet modified the firewall nor done the ip port-map command. It does work from the LAN side to Self since that zone-pair is more forgiving, however, it works on both 22 and 2340 which I thought odd since I thought the ip ssh command changes the SSH server listening port.
I have not yet permanently set the ip port-map command. However I ran it once and then did a sh ip port-map ssh
This showed system defined ssh port maps for tcp and udp on 22, and then my user defined one for tcp port 2340. Interesting that the system-defined ones are both UDP and TCP - I thought SSH was TCP only.
According to the IOS command referendces (for release 15.2), I should not be able to remove the system-defined port map entries as it would give an error. However, I did no ip port-map ssh port tcp 22 and the same for the UDP entry and they disappeared - so now for sh ip port-map ssh I get no results returned. Yet, SSH still works on 22 and 2340.
Be that as it may, after some further testing I've concluded that with or without use of the ip port-map ssh port tcp 2340 entry, SSH works (from LAN to Self) on either port 22 or 2340. It seems ip port-map has no effect on the SSH server itself (?). Or perhaps PAM is overridden by the ip ssh commands?
So at that point I decided to stop testing, not doing anything with firewall yet, until I understand things better. So far, the IOS is very confusing in it's behavior.
Changing the SSH server's listening port via ip ssh command to something other than 22 seems to not actually change anything, it just adds that port in addition to 22.
Port-application mapping appears to have no effect on the SSH server (I have not tested whether ip ssh overrides PAM or vice versa)
So far there seems to be no way to actually change port 22 usage - even "deleting" the PAM entry for ssh via 22 has no effect.
Confusing!

Changing the listening ports of ARD

I know how to change the listening port of SSH from 22 to some other number.
Is there any way to configure ARD (in plist maybe?) so that it can try connecting to SSH on a non-default port number.
Whilst I know how to secure SSH (not properly secured in OS X by default) I would rather change it's listening port to avoid the traffic that will simply try to bruteforce in.
So if I edit ssh_config and sshd_config on my Macs will this break ARD? Or if these conf files are properly edited (ssh_cnfig on client changed to port 22222 and sshd_config on server changed to 22222) will ARD connect seamlessly?
In short does ARD absolutely need Remote Login (SSH) to be running on the default port 22?

hmm okay, but i don't need to port forward 22 from my router to my mac to allow ARD access, only ports 5900, 5988 and 3283.
That improves things since 22 is not visible to the WAN.
Still, I'd like to know the answer to my question in the previous post.
And what about re-mapping VNC from 5900 (another obvious target although prob not vulnerable to VNC exploits since I expect Apple have modified this service and somehow hooked it into the authentication of the ssh protocol)?
