Help with listener.ora

I'm trying to set up my linux box so someone can telnet in and run a couple of queries in SQL*PLUS. I have th tnsnames.ora file setup correctly - I think. I'm not sure what I'm supposed to do with listener.ora. I know that this file is used by lsnrctl. Can someone give me some help with this? Thanks.

How did u know that your tnsnames.ora works, when you have not setup listener.ora?
Anyway, this might help:

Help with Listener.ora file location on Suse Linux

Hi
Ok, 2 scenarios
Scenario 1
Installed Oracle 10.1.0.3.0 on Suse 9.2, the location of the listner is: /oracle/dborafiles/application_name/instance/admin/netadmin/
Which is great, as this is where i want the listener and tnsnames.ora files to be under.
Scenario 2
Installed Oracle 10.2.0.1.0 on Suse 9.2 (using exactly the same method for doing the above instllation), and for some odd reason, the location of Listner and tnsnames.ora files are under:
/oracle/dboracle/orabase/product/10.2.0.1.0/network/admin/
This is the wrong location for me, I want the listner and tnsnames .ora files to be under same like scenario 1.
2 Questions:
Q1: why the listener.ora and tnsnames.ora files are diffrent location in Scenario 2 comapred to Scenario 1.
Q2: How do I correct it.
Note: the TNS_ADMIN in .profile is exactly the same for the above 2 installations, changed the applciation name and sid offocure, but all the same:
TNS_ADMIN=/oracle/dborafiles/applicatio_name/instance_name/admin/netadmin
export ORACLE_SID ORACLE_BASE ORACLE_HOME PATH
Can someone please help?

For a long time now, the tnsnames and listener files have been placed in the ${ORACLE_HOME}/network/admin by default. That is the location that the installer will create these files in.
Don't know why 10.1.0.3.0 install created the files in that folder. That is not the default behaviour in versions prior to this and versions after this.
Check the settings of the environment variables that were in effect at the time of 10.1.0.3.0 install.

Trouble with listener.ora and tnsnames.ora

I can't get the listener running.
Trying to start the listener results in the following message:

TNS-12560: Message 12560 not found; No message file for product=network, facility=TNS
I suspect i have a configuration error in listener.ora or tnsnames.ora, but I'm stumped at this point.
Can anyone help?
Much appreciated.

Assume you've got $ORACLE_HOME
We'd end run listener problems by setting/exporting TNS_ADMIN and putting tnsnames.ora and listener.ora files in a standard place ( ../dbs for our site) rather than Oracle's defaults.
We'd also found that there is a parsing problem of the tnsnames.ora file by 9.2 ( its in AIX and MAC versions at least). Placing the entire description section on a single line consistently resolved problem.
Opening a Tar on that one.
So Now we're accessing Dbs based on mac and AIX from Multiple MAC and AIX remote sites with SQLPLUS and thin clients.

Grad student needs help with Listener

I am doing my Masters project on Distributed Database and am trying to connect 4 database to one listener on one machine. The first two appear to connect OK as listenermral and listenermrny. But the next two keep on giving me TNS-01150 errors-address of specified listener name is incorrect. I check with Metadata and the suggestion was to build the listener.ora file with netmgr, but it hangs when I launch it. This is my code:

Thanks in advance for any help

Fedora is free and Oracle has given it the thumbs up. Plus there are tons of docs available, from installation to trouble shooting. I would go with Fedora, especially since it won't hurt your budget.

I like to see that show me with pictures as I am new in this aspect of oracle .... and want to learn it .... thank you very much

Hello friend..
The error you are getting *"ORA-27101: shared memory realm does not exist"* may be coz you are trying to connect to your database which is already shutdown not as sysdba user but as some other user, becoz of which you are getting this error. It sometimes happen that the service of the database is already started but when you try to connect to a shutdown database as users other then sys even having the DBA priviledges you cannot connect to database.
Try to connect as SYS user hope your problem will be resolved.

Need Help with Listener on JInternalFrame

Below is the code as it is currently.
public class addCustomer extends JInternalFrame implements ActionListener{
//Variable declarations here
private JPanel panel = new JPanel();
private JLabel label1,label2,label3,label4,label5,label6,label7,label8,label9,icon1;
private JTextField CustNum,CFName,CSName,Address1,Address2,City,PostCode,Tel,Cell;
private JButton Cancel, Add;
private ImageIcon pic,FrmPic;
addCustomer() {
super ("Add New Customer",true,true,true,true);
setSize(350,370);
setResizable(false);
On the Frame I have a textfield that I would like to add a listener to. When text is typed into the textfield it should enable a JButton on the frame. My problem is that as soon as I implement KeyListener or EventListener on the above code I get an error of the class is not defined as abstract. If I define it as abstract my main declaration that looks like this gives me an error :
public static void main(String args[]){
new Video().show();
Can anyone help me with a work around.

Help with Listener design please

i have an JFrame with a bunch of components...i guess i want all the interactive parts (buttons, jtextfields) to use the same actionlistener...
but i dont want the jframe class to implement it an actionlistener but to use its own listener obj
the one good thing about a class implementing a listener is that the listener has access to all the classes variables (buttons etc), how do i separate the listener into its own class while having access to the implementing class' variables?
this is the way im doing it now
public class IssuePoolListener implements ActionListener{
    private IssuePoolGUI2 owner;
    private JTextField symbolField;
    private JTextField descField;
    private JTextField searchField;
    public IssuePoolListener(IssuePoolGUI2 owner){
        this.owner = owner;
        symbolField = owner.getSymbolField();
        descField = owner.getDescriptionField();
        searchField = owner.getSearchField();
    public void actionPerformed(ActionEvent e){
    //have access to owners variables
}its ugly.
if i where just to have
public class myJFrame imlements ActionListener{
//all myJFrame code [maybe lots of lines]
    public void actionListener{
    //maybe lots of lines
       if(command.equals(blah)
          blah();
       else if(command.equals(blah2)
           blah2();
       etc
blah(){...have access to all variables...};
blah2(){....have access to all variables...};this way i dont need all those getters, but the myJFrame class is way bigger...
is there a better way? thanks

If the task is small, most any approach will eventually succeed. But you should get in the habit of
writing cohesive classes. And when it comes to making ActionListeners, I like using Action.
As far as the division between your frame (or GUI class) and the ActionListener, if your Listener
knows about IssuePoolGUI2 , methods getDescriptionField and so on, it is then so closely tied to
your GUI class it might as well be part of it -- say an inner class.

Problem With Listener Service: Long Delay Starting Listener, Intermittent Connections

I am having trouble connecting to my Oracle database. I'm not sure what the cause was, but now when I connect to a database that has been working fine for the past two years, I usually get a ORA-12541 error.
I run lsnrctl status on the server and get a prinout like this:
Copyright (c) 1991, 2010, Oracle. All rights reserved.
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=dqaswn02)(PORT=1521)))

TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
   64-bit Windows Error: 2: No such file or directory
I've also tried manually stopping the service via services.msc and then restarting via lsnrctl start, but when I do this I get a really long delay (10+ minutes) before it returns with something like:
TNS-01153: Failed to process string: 0í≈♥
I'm pretty lost as to what is wrong. I've been messing around with listener.ora, but I don't see anything problematic in there. Here's a copy:
# listener.ora Network Configuration File: E:\app\myc0714\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora

LOG_FILE_LISTENER = LISTENER
TRACE_LEVEL_LISTENER = SUPPORT
TRACE_FILE_LISTENER = LISTENER
However, a few times during this I've been able to connect to the server, via sqlplus, but it has taken 10 minutes before the connection comes online. Once I'm connected, I can query my tables as expected, but I need an application to connect.
If anyone has any ideas on what could be wrong, please let me know.

When I opened up netca, I didn't have any listeners configured, which seems very strange. When adding it, I get this message in the cmd window:

I killed the service via services.msc again and tried starting the lsnrctl. This time I've got a new listening service going:

Listener.ora file on RAC 11gR2 with SCAN

Hello,
I have 11.2.0.1 Rac with 2 nodes configured to work with SCAN.
The following listener.ora file was created during the rac installation.
(I only changed the name of the instance to XYZ in the output bellow).
There is only one listener.ora file for both the rdbms instance and the ASM instance.
Is it a good best practice or should i consider to create a seperate listener.ora
to the rdbms instance and to the ASM instance ?
The listener.ora is look as follow:
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_XYZ_=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_XYZ)))) # line added by Agent
LISTENER_SCAN3=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3)))) # line added by Agent
LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN2=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN3=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_XYZ=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by AgentLSNRCTL> show current_listener

Is it a good best practice or should i consider to create a seperate listener.ora to the rdbms instance and to the ASM instance ?No, you should not be creating separate listener for each Grid & DB. Listener is node specific resource. Oracle recommends in RAC environment the listener should be configured from GRID home and it will be able to serve both Grid and DB services.
It also helps in maintenance where as you can upgrade DB without bothering Listener, can have several db instances, and can have several versions of DB supported by a single listener.
I hope this answers your question. if yes please mark the question as answered and do not forget marking answer as a Correct answer.

This makes no sense. You don't configure a listener nor a tnsnames.ora "in a database".   I hope this is just a language issue and not reflective of a fundamental misunderstanding of how tns works.

Need help solving listener and Oracle problems with Mac OS X 10.4 "Tiger"

I have Oracle 10g working on Mac OS X 10.4 "Tiger" except for the listener and Oracle net 8 configuration. I have not been able to get the Oracle listener to work with my built in Mac Airport wireless network card or built in ethernet card. I keep getting the errors
connection refused cannot start listener. Can anyone offer help?
Thanks

Hi Ben,
how does your listener.ora look like ?
Mine is:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ronald-g4-eth)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = ronald-g4-wifi)(PORT = 1521))
and listens to the ethernet and airport address.
When do you get the problems ?
regards,
Ronald

Configuring tnsnames.ora / listener.ora with HOST = localhost

Dear Oracle experts,
presently I'm trying to configure an Oracle installation on a Win2k server
to work with HOST = localhost entries in my tnsnames.ora and listener.ora.
I have to do that because I want to use that Oracle installation as an image
for several computers which will get different IPs and computer names.
My problem is, taht I only can configure my entries with a real IP adres (127.0.0.1 does not work ) or with the present name of the system but not with localhost or 127.0.0.1.
My listener.ora looks like below :
# listener.ora Network Configuration File: D:\oracle\product\10.1.0\Db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SDU = 4096)
(SID_NAME = EMS)
(ORACLE_HOME = D:\oracle\product\10.1.0\Db_1)
(PRESPAWN_MAX = 10)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost )(PORT = 1521))
The listener above lead to a
ERROR - ORA-12541: TNS:no listener
if I try to connect via iSQLPlus. If I exchange HOST = localhost with HOST = mydnsname the I can connect to the computer via isqlplus.
Is there any possibility to configure the listener and tnsnames without using real IP adresses ?
Best regards,
Daniel Wetzler

Hi maran,

But I cannot conect to my database....
I pasted my tnsnames.ora below.
Perhabs there's a bug I didn't fins yet. But if I replace in both files t(tnsnames.ora and listener.ora the "localhost" with my local IP it works just fine...

What's wrong with my listener.ora?

Hello.
I must say I've never understood how listener.ora works (it used to work but someone modified it), but by now it'd be enough to know what's wrong with this:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = zippo)(PORT = 1522))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = CSR2)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = CSR2)
My problem is that when I try to connect from my PC "sqlplus csr_admin@csr2/csr" I get "ERROR: ORA-12154: TNS: could not resolve service name"
This is my entry in my local tnsnames.ora:
CSR2.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = zippo)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = CSR2)
An this, the entry in the entntry at the server's tnsnames.ora:
CSR2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = zippo)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = CSR2)
Release 9.2.0.3.0
Thanks in advance.

It's funny but the date I posted this topic isn't OK (more than 3 years ago)
