I tried to recreate the listener with netmgr, netca but I got this:
[oracle@serverbd bin]$ ./netmgr
**** ORACLE_HOME environment variable not set!
ORACLE_HOME should be set to the main
directory that contains Oracle products.
Set and export ORACLE_HOME, then re-run.
[oracle@serverbd bin]$
[oracle@serverbd bin]$ ./netca
**** ORACLE_HOME environment variable not set!
ORACLE_HOME should be set to the main

Set and export ORACLE_HOME, then re-run.
[oracle@serverbd bin]$
Just in case, I could startup normally the database.
What can I do???

I renamed the listener. ora file to listener.org and run this env|sort this is the result:

Can not startup the oracle db after reboot

Hi.
I have an Oracle 10g DB running on Linux9 server. It works well before I reboot the server this morning. I can not startup the db.
$ sqlplus /NOLOG
SQL> CONNECT sys/password AS SYSDBA
Connected to an idle instance.
SQL> STARTUP
ORA-17503: ksfdopn:2 Failed to open file +DATADG/orcl10g/spfileorcl10g.ora
ORA-15055: unable to connect to ASM instance
How can I do to restart the db??
Any hints are highly appreciated.

Yes, it seems all right. But the real problem is: after I start listener,
Oracle Enterprise manager 10g Fatabase Control and iSQL*Plus, I can not connect to the http://localhost:5500/em. The Alert says: The connection was refused when attempting to contact localhost:5500.
I can connect to the iSQL*Plus. I mean, the http://localhost:5560/isqplus/, but can not login. The Error says: ERROR-ORA-12514: TNS: listener does not currently know of service requested in connect descriptor.
When I see the status of listener,

And How can I check the db is startup? If the db is started, can I use sqlplus even without listener?

When I upgraded iOS 7.1 software when a call comes in I can not click the "listen" when the screen is in lock mode

when I upgraded iOS 7.1 software when a call comes in I can not click the "listen" when the screen is in lock mode

User troubleshooting steps as outlined in the manual include restart, reset, restore, restore as new. Have you tried any of these? Restart involves powering off your phone and powering back on. Reset involves the following procedure:
Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)

Can I startup the Powerbook from an Iomega external CD burner?

Can I startup the Powerbook from an Iomega external CD burner? We no longer have the removable internal drive. The computer will not start up, and I need to start it up on a utility CD from an external drive, but I've been unsuccessful so far. The external drive is an Iomega CD-RW/DVD-ROM drive.
Thanks for any help.

If the external drive is an USB drive, you probably can't boot a Mac OS X disk from it; the only known exception is an USB 1.1 drive with the Tiger DVD on a clamshell iBook.

Then I checked for the listener.ora under admin dir and there is no listener.ora file there.I think,there should be that file because in my first installation of oracle 10g developer suite,I am aware of there is listener.ora and in that time ,I have some trouble connecting to the database from sql plus and can't login .So I deinstall and reinstall after that I have no listener.ora file.I hope somebody can help me out.
I have oracle 10g developersuite and oracle xe database installed.Anybody can advise me from the scratch because I am just a beginner.Thanks.

I already configured three listeners and tested it by call lsnrctl start and lsnrctl status and the error is still the same :

How can I add the listener to the CellRenderer

My class named NoteColumnRenderer extends DefaultTableCellRenderer
and thhe getTableCellRendererComponent() returns JButton .
My question is how can I add MouseMotionListener to the JButton
or how can I add MouseMotionListener to the NoteColumnRenderer ?
The code below,and there is no effect
public class NoteColumnRenderer extends DefaultTableCellRenderer {
public NoteColumnRenderer(boolean multiSelection) {
super();
System.out.println("b="+this.getListeners(MouseMotionListener.class).length);
this.addMouseMotionListener(new MouseMotionListener(){
public void mouseDragged(MouseEvent e) {
System.out.println("mouse+++++++");
public void mouseMoved(MouseEvent e) {
System.out.println("mouse-------");
m_button.addMouseMotionListener(new MouseMotionListener(){
public void mouseDragged(MouseEvent e) {
// TODO Auto-generated method stub
System.out.println("mouse=====");
public void mouseMoved(MouseEvent e) {
// TODO Auto-generated method stub
System.out.println("mouse=======");
System.out.println("a="+this.getListeners(MouseMotionListener.class).length);
m_multiSelection = multiSelection;
if (m_multiSelection) {
     m_check = new JCheckBox();
m_check.setMargin(new Insets(0, 0, 0, 0));
m_check.setHorizontalAlignment(JLabel.CENTER);
          } else
m_button.setMargin(new Insets(0, 0, 0, 0));
m_button.setSize(new Dimension(5, 5));
m_combobox = new JComboBox();
     } // IDColumnRenderer
     /** Mult-Selection flag */
     private boolean m_multiSelection;
     /** The Single-Selection renderer */
     private JButton m_button=new JButton();
     /* The Multi-Selection renderer */
     private JCheckBox m_check;
     private JComboBox m_combobox;
     protected void setValue(Object value) {
          if (m_multiSelection) {
               boolean sel = false;
               if (value == null)
     else if (value instanceof Boolean)
          sel = ((Boolean) value).booleanValue();
               else
          sel = value.toString().equals("Y");
               m_check.setSelected(sel);
          else
               if (value == null)
               else
     if(value.toString().length()>10)
m_button.setText(value.toString().substring(0,10)+"...");
                    else
                         m_button.setText(value.toString());
                    m_button.setBackground(Color.WHITE);
     public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
          setValue(value);
          if (m_multiSelection)
               return m_check;
          else
               return m_button;
}

Listener can be added to a cell editor, not cell renderer.
Set relevent cess(s) to setEditable == true when you use your custom cell editor.

Urgent: can not startup the database in unix server

hi...i am facing a treamendous problem...
to shutdown the database(unix environmment), I have connected through putty and from there in the sysdba login, I have given the command "SHUTDOWN IMMEDIATE"
but after that suddenly the power failure occurred and my local machine from which i was accessing the unix server, got shutdown..
after the restart, when I am again accessing the putty and connected to the oracle11g server and from sysdba login, given the "STARTUP OPEN" command, then it is showing the error...
SQL> startup open
ORA-10997: another startup/shutdown operation of this instance inprogress
ORA-09968: unable to lock file
Linux-x86_64 Error: 11: Resource temporarily unavailable
Additional information: 29770
please help...its very urgent..

My advice is, as your request is 'urgent', you submit a Service Request at level 1 at My Oracle Support.
This is a discussion forum and not a support forum, and it is manned by volunteers, not by Oracle Support Engineers.
Thank you for your current and future cooperation not to submit 'Urgent' requests in a forum of volunteers.

I had anof of Nvidia how can we make the listen???

okay i have been having thsi problem the last 4 days with my GFX Geforce 9600GT i customiced it with a Thermalright cooler and a low noice fan.
ever 15 sek i get a black out on my screen and 15 sek after the game comes back up.
windows Vista64 comes up with this
Display Driver Stopped Responding and Has Recovered
i have used 4 days now to find out what could be the problem,
and there is no awser.
there ar a thread on Nvidia's forum with more that 250threads in it only regarding this subject, and Nvidia has don NOTHING, not even awserd the thread....
thinks i have done;
got the lates drivers
got Beta drivers
got oldes driver
used driver from my CD that came with my card
i made a TdrLevel (3) in the Regedit
i forced the new drivers to expand and old NVL.in_ file into its folder as a NVL.ini
i tryed running without driver (not a sucses)
and alot more.
and i have read and read and read up on people whining over there GFX has been ruined. its sad to have a new GFX that just breaks becouse of sofware, couse most firms in scandinavian wont take things in return unless its hardware related
and now...im givving up. i siply cant find an awser for what to do.
maybe if MSI phoned up Nvidia and got some awsers, that might help
NinZ :D

i have been running XP pro before with the modification, and now problem at all. i have not tried the card in another PC, since im very sure of its not a HArdware problem, but a Vista64bit/nvidia driver problem.
if u go google; Display Driver Stopped Responding and Has Recovered
u will find out that there are people in 10.000 that are having hte same problem as we speak and some evne had it for a long long time.
her are my specs
# Intel Q9300 2.5 @ 3.1Ghz (i have also tryed it stock, but didnt help)
# MIS P35 platnium Combo
# Crosair TwinX2 Dominator 4x1Gb 1033Mhz
# MSI Geforce 9600GT
#2x500Gb sataII
# luquid cooling on CPU
# Vista64bit SP1

thx for the fast respons btw^^

Can't get the listener to read the selection

All I want my code to do is read the name selected in the JComboBox and print it to the GUI. However it doesn't seem to want to work. It's not reading the ComboBox and getting the string. Here is the code I'm working with trying to get it to work. Any help would be appreciated.
public FriendSearchPanel()
String[ ] friendStrings = {"Select...", "David", "John", "Dustin", "James", "Charnetta", "Dozier" };
         JComboBox friendList = new JComboBox(friendStrings);
         friendList.setSelectedIndex(0);
         friendList.addActionListener(new ComboListener());
inputLabel1= new JLabel("Select a friend to help:");
outputLabel1= new JLabel("");
help = new JButton ("Help friend");
         help.addActionListener (new ButtonListener());
add (inputLabel1);
         add (friendList);
         add (outputLabel);
private class ComboListener implements ActionListener
         public void actionPerformed (ActionEvent event)
            if (event.getSource().equals(friendList))
               String name = (String)friendList.getSelectedItem();
               outputLabel.setText(name);
      }

in your FriendSearchPanel() constructor you have this
JComboBox friendList = new JComboBox(friendStrings);
which makes friendList local to the constructor.
then in ComboListener's actionPerformed() you have
if (event.getSource().equals(friendList))
if the compiler does not produce an error "cannot resolve symbol - friendList"
then you must have friendlist also declared as an instance variable
try changing
JComboBox friendList = new JComboBox(friendStrings);
to
friendList = new JComboBox(friendStrings);

How can I know that the listener is starting up?

Hi,
I follow the instruction in ACS Oracle Installation guide. I believe that many of you use the document to install oracle. I have a question when I try to start the listener. when I execute ./listener8i stop or ./listener8i start I got the same message, which is different from the message in the ACS document.
Here is the message:
Oracle 8i listener start/stop
Startting the Listener for 8i:
LSNRCTL for Linux: Version 8.1.6.0.0 - Production on 31-AUG-2000 14:00:00
(c) Copyright 1998, 1999, Oracle Corporation. All rights reserved.
TNS-01106: Listener using listener name LISTNENER has already been startd.
Is the message above correct? How can I know the listener is started up?
TIA,
Tony

try "lsnrctl status" on the linux command line.
for further info use "lsnrctl help"

The Listener

Hi
I am calling functions from .so files from the Developer PL/SQL. These .so files are on the database server. How do I set the LD_LIBRARY_PATH for the extproc listener? Or Is there anotherway to tell the listener to tell the place of the library files.
PS. The first library path and file name is specified with absolute path in the create command.
Help Please
Regards
Santosh

That is normal, because the instance will register itself with the listener when an actual connection request is made. That is the automatic-registration feature of oracle.
Alternatively, you can add a SID_LIST_LISTENER (or was that SID_LISTENER_LIST?) entry to your listener.ora, so that you will get "the listener supports the following services" automatically after you startup the listener.
null

Where is the listener on this server?

I read that the listener is the main server side networking component that allows connections to be established between clients and the Oracle database.
I am looking at the listener file on my machine to follow along.
However, when I try to find the listener.ora file on a different server here in the company I work in, I cannot locate it. (Not in the Network folder, not anywhere).
Why is this? Is the information needed to listen for client requests simply held in the tnsname.ora folder (which I can find on the server side).
Any bright ideas, thanks a million.

(I have tried the lsnrctl in the command line, but just get the message that its not recognised as an internal or external command.)

listener.ora is the file used to configure listener it is located at the ORACLE_HOME/network/admin at the database side. If ever it is changed, it is located according to the value of the TNS_ADMIN environment variable.
listener.ora can only be found on db server installations, not on client installations, just in case you are looking on the wrong oracle home.
When you type:
lsnrctl statusyou can see where the listener is located by this line:
Listener Parameter File G:\Oracle\product\11.1.0\db_1\network\admin\listener.ora
Listener Log File G:\Oracle\product\11.1.0\db_1\network\log\listener.log~ Madrid

I can't start the WebLogicServer after open the -ea option BEA-000386

After I set the JAVA_OPTIONS=${JAVA_OPTIONS} ${enableHostswapFlag} -ea* in the setDomainEnv.sh file,I can't startup the server.
It threw the fllowing exception:
<Critical> <WebLogicServer> <BEA-000386> <Server subsystem failed. Reason: java.lang.AssertionError: The ManagementService has not been initialized & runtimeAccess is null

Thank you for your hlep!

I am having the exact problem. We need to enable assertions (-ea) because we have a continuous integration environment setup which automatically deploys our application onto WLS and runs tests against it. Those tests require that assertions be enabled. It's a fairly common practice and we have never had an issue on previous versions of WLS (all the way back to 8.x). Our "last known good" version that this worked on was WLS 10.3.0.
Any suggestions?

I can't startup the listener
