Listener problem

Hello,
I have created new database and added connection string in to tnsnames.ora file but i am not able to connect with new database remotely.

Message Listener Problem (iDoc)

I am receiving an iDoc successfully in the Message Listener within Mii. I have created a Processing Rule for the Message Type and tied it to a simple BLS. The BLS has an XML input parameter which is selected in the Processing Rule.
The BLS simply maps the XML input parameter to an XML output parameter and that's it as I want to make sure communication is working before creating any BLS logic.
The iDoc Message goes into failure status and this is what I get in the log:
Unable to process request com.sap.jms.client.message.JMSObjectMessage@431f1d25
[EXCEPTION]
com.sap.xmii.bls.exceptions.TransactionLoadException: Unable to create transaction instance
Any ideas why this is happening?

After much searching and trial and error, I was able to locate the source of this problem. While I was modifying the "Log Level" in the Processing Rule, someone else changed the Transaction Security to include the "SAP XMII Developer" role. Once I remove this role from the BLS, the same symptom occurs.
It seems this is the only role that allows the Processing Rule to trigger the BLS's. Is this hard coded somewhere in Mii that this role is required? If so where can I find these types of requirements so I can avoid going through this for other Mii functionality in the future?
Thanks

On metalink, solutions are client side, but I have this problem on server side.
I try to change host name to ip add, but problem persist.
I try to reboot server (because I think the problem was the oracle istance) but the db works correctly.
What can I do?
thank u so much!!!

Hello Pedro,
Please can you tell me if you resolved this issue you were having and how did you resolve this. I am having the same issue now....
We did a restore to a different box and now cannot connect to the database and having same issues you described.
Your help will be appreciated,

Oracle Listener Problem

I am having a problem starting the Oracle Listener after a system crash on Windows NT.
However, if I first connect to the internet and then try to restart, everything works ok.
Why should I have to connect to the internet with my laptop in order to start the Oracle Listener?
The message I am getting is as follows.
C:\WINNT\Profiles\timh\Desktop>net start OracleStartORCL
The OracleStartORCL service is starting..........
The OracleStartORCL service was started successfully.
C:\WINNT\Profiles\timh\Desktop>net start OracleTNSListener80
The OracleTNSListener80 service is starting.
The OracleTNSListener80 service could not be started.
A system error has occurred.
System error 1067 has occurred.
The process terminated unexpectedly.
null

some more info.
Given below is the output of status. does anything look bad or am I doing something wrong?
for the service"abcd" it says has two instances, one of the status is unknown. does that matter is it always like that or I am asking very dumb questions?
Please excuse me if that is the case.

9.2 and 10g on same machine, listener problem

Hi,
i had a 10g db on a solaris server. then i installed a 9.2 database on this server. I know that i should use the 10g listener for 9.2 database.
But i cant manage to configure it correctly.
The 10g listener name is LISTENER and 9.2 listener name is TPRS.
what i did ? i opened netmgr and created a new listener named TPRS. added the database to it.(on the menu database services)
when i try to start TPRS i get the following error message
bash-2.05$ lsnrctl start TPRS

oracle   28694 17439 0 17:49 pts/0    00:00:00 grep tnsYou can choose for a "more than one listener" solution or "only one listener". Whatever you do the unix user that starts the oracle, listener executables have to be the same OR sicky bits have to exist on the executables (so the user is allowed to start the executables and access the memory realms as if it was the actual owner).
The moment you don't use the defaults - aka "LISTENER" or a non default port (1521), you will have to define this via the database parameter
LOCAL_LISTENER
SQL> conn / as sysdba
SQL> show parameter local_listener
NAME                                 TYPE        VALUE
local_listener                       string
SQL> ALTER system SET LOCAL_LISTENER=
        "(ADDRESS=(PROTOCOL=TCP)(HOST=sun3.tuprasnet.local)(PORT=1522))"
        scope=BOTH;
System altered.
SQL> show parameter local_listener
NAME                                 TYPE        VALUE
local_listener                       string      (ADDRESS=(PROTOCOL=TCP)(HOST=sun3.tuprasnet.local)(PORT=1522))Now the database "knows" that it has to register itself against "sun3.tuprasnet.local" and will be serviced via port 1522.
After been set on database level, the "LOCAL_LISTENER" value can be resolved via the string itself or (*most common way of doing it is using a tnsalias*) is resolved via the tnsnames.ora file (the string given in LOCAL_LISTENER is an tns ALIAS).
If you use ONE listener, then databases can register themselves against SQL*Net compatible listeners. So you don't have to use a 9i listener for a 9i database. A 10g database is also allowed.
If I use a ONE listener solution, then I normally pick the listener from the highest database version and let all database versions use this listener.
The post given here (http://www.liberidu.com/blog/?p=116): "Registering non-default XMLDB HTTP/WebDAV and FTP ports on a non-default Oracle Listener port" describes a use case which is even more "extreem" regarding shared server functionality, based on TWO listeners and NON-DEFAULT PORT addressing, based on an Oracle 9 and Oracle 10 environment on the same machine.

OAS 4.0.8 http listener problems

I am running OAS 4.0.8 on NT w/ SP5. I followed the instructions for install in the latest (Jan 2000) release notes. The problem I am having is with the listeners. The admin and www default listeners start up fine, but if I create a new listener, it will not start up. The error message tells me to check the NT Event log but there is nothing there. Also there is no svwww.err file available to check because it never starts!
I am completely lost on this one. Any help is appreciated.
Thanks

Try to use root for startup. Remember that port bellow 1024 is protected for root only.

Menu/submenu managing and Event Listening problem

Hi guys,
I'm creating a flashwebsite and I've got a problem with submenu appearing/disappering.
What is extremely easy in html/jquery is taking me overburned in actiuonscript: make appear a submenu only when the mouse cursor is over its button and not over itself.
Indeed I've my button/MC, that contains its submenu (which is a vertical list of MC), and when I go over it, submenu appears, when I leave, sub menu becomes invisible.
BUT, when I go over the space under the button (where my invisible submenu is), submenu become visible another time. I know that cause is the listener associated to the main button is linked to all its nested MC.
My question is: there is a way to declare a listener only to a MC and not for all is nested elements?
If not, what shopuld I do for my pourpose?

        item.addEventListener(MouseEvent.MOUSE_OUT, function(e) {
            for(var i:int = 0; i < subMenuAnim.length; i++){

        item.visible = false;
        item.coccinella.rotation = (Math.random() * 200);
        nav_container.addChild(item);

What are you doing to make the submenu invisible? If you set its visible property to false it should not interact with the mouse, but if you are changing its alpha property to 0, it will react.

Parallel Port Listener problem

hello everyone,
I have downloaded the javax.comm package and installed it as given in the installation instructions. I can print my files using the javax.comm classes. But i do not get the Parallel Port Event even if i register a listener.
Also for all the methods such as is PrinterError(), isPrinterTimedOut(), isPaperOut() etc i do not get anything else but flase. Even if the printer is online or not, or if the paper is out etc, in all cases only false is returned by these methods. Please tel me what could be the problem.
All these methods return false even when the printer is online or not :
parallelPort.isPrinterBusy()
parallelPort.isPrinterError()
parallelPort.isPrinterSelected()parallelPort.isPrinterTimedOut()
parallelPort.isPaperOut()

Well, i think you should be looking for specs about the printer(s) to find out how they communicate with windows. That might not be that easy because not all company's will be very open about that. You should realise that any message windows gives you about the printerstatus comes to you via the drivers for that printer. The drivers know how to communicate with the printer, and that's different per printer.
The most used standard for printing is Postscript (I believe HP6L is a postscript printer) wich is supported by the 'bigger' printers. There will be info about Postscript on the web, but it is owned by Adobe and I son't know how free the specs are...
An older dot matrix printer is more likely to be using the lines that are signal out busy, error etc. You will find the pin layout here: http://www.doc.ic.ac.uk/~ih/doc/par/doc/regpins.html
If all your after is printing your files you might want to use java.awt.PrintJob wich will let you print through the spooler of the operating system, thus letting the OS handle the printer with the right drivers.

HTTP Listener problems

Good day all,
I have some problems regarding HTTP Listener:
1. I cannot startup my www listener on port
80, only Node Manager listener can be
started. It gives out the errors:
OWS-08811 & OWS-08851.
2. I even cannot either view or edit the
configuration for my HTTP listener.
When I clicked on the properties such
as Network, Server, etc, it just doesn't
show up the configuration that I needed
to see.
I have already checked the environment variable: WV_GATEWAY_CFG, and it is in the right path. What could possibly went wrong?
This is the specification of my installed products:
Platform: Windows 2000
DB: Oracle 8i Enterprise Edition 8.1.7.0.0
Oracle 9ias 4.0.8.2.1a
Any ideas? Thanks.
- Alfian

As far as I know, there is no utilities to view the configuration as you have mentioned. All configurations are in configure files,
they are
httpd.conf
jserv.conf
jserv.properties
zone.properties
If someone does know such a utility, please tell me. :-)

I've read on this list that it might be a shared_memory_pool problem, So I
think I've maxed out the mount of shared memory. This is a Sun Fire V240
with 8G RAM, so /etc/system has:
*set shmsys:shminfo_shmmax=268435456
*set shmsys:shminfo_shmmax=4294967295
set shmsys:shminfo_shmmax=8254455808
set shmsys:shminfo_shmmin=200
*set shmsys:shminfo_shmmni=200
set shmsys:shminfo_shmmni=1024
set shmsys:shminfo_shmseg=1024
set semsys:seminfo_semmap=250
set semsys:seminfo_semmni=500
set semsys:seminfo_semmsl=500
set semsys:seminfo_semmns=2000
set semsys:seminfo_semmnu=500
set semsys:seminfo_semume=100
set semsys:seminfo_semvmx=32767
set semsys:seminfo_semopm=100
set noexec_user_stack = 1
I am totally at a loss as to what the issue might be save some new tags
needed in listener.ora... Any pointers/help more than welcome...

well, oracle's path seems to see 10g's version of the listener:
hosts% which lsnrctl
/data/oracle/app/oracle/product/10g/bin/lsnrctl
I'm running this on the same host. ie loopback.
After the error, the listener seems to be in the process table - but nothing can talk to it:
oracle 856 818 0 20:05:06 pts/2 0:00 egrep lsnr

URGENT!! 8.1.6 / 7.3.4 on same box - LISTENER problems

Hi all!
Ever had one of those days? I have installed 8.1.6 onto our 7.3.4 server as directed in the installation notes etc.
I have amended the listener.ora file as directed and this contains both the 7.3.4 instance and 8.1.6 instance. You can log on to the 8.1.6 via SQL*Plus with no problems, but when you try to get to the 7.3.4 instance, you get:
ORA-12500: TNS:listener failed to start a dedicated server process
Heellppppp!
Thanks and regards,
GR

Hi All,
I am trying to confugure the listener services on an existing Oracle 7.1.6.2 running on Digital Unix 4.0f. I installed Net Services from Oracle 7.2 CD ad with this Listener was installed successfully. But when I try to connect the server it gives the error oRA-12500.
Can anyone comment on this.
Tks,
Ravi
I ran into a bug (specific to my os - digital unix) when running an 8.1.5 listener and trying to connect to 7.3.4. It sounds like this may be the issue if you are on digital unix - the bug number is 740014.
Hope this helps.

URGENT : EVENT Listener Problem

Hi All,
Thanks for your time. I am facing a Small issue with Event
dispatcher and Add Event listener. Well i will explain the problem.
I am having one MovieClip named BUTTON_SET and i gave
"ButtonSet.as" as linkage Class.
Inside that BUTTON_SET i am having some Buttons and they are
also having "UIButton.as" as linkage class
UIButton Dispatching press and release events, But unable to
capture it using ButtonSet Class. Here with i have attached the
Code and i gave the Source URL Too.
upto my Knowledge : UIButton class is not initiated When the
ButtonSet is ready to addListener.
Please Help me to fix this.
if i don't find a solution i need to change all my class
structures.
CLICK HERE FOR SOURCE
CODE

According to your Code, When you are calling the InitHandler
Functionction the Buttons may/may not be Initiated. So use the
Enterframe to check whether its loaded or not.
Write down this in the ButtonSet to replace the init Handler
Call.
this.onEnterFrame = Delegate.create(this, initHandler);
inside the initHandler remove the function This will help you
if you are not using any Enterframe for any other manipulation)
delete this.onEnterFrame;

Listener problem in our production environment

Hi Everyone,
I faced a problem in our production primary DB like

Listener problem when "unloading" externaly loaded SFW's

Sorry for double post!
While loading an external SWF in to an Flex application is
easy, removing it again seems to bring a few problems.
What i want to acomplish is the following: Make a portfolio
website in Flex, in which i can show images, movies and SWF's.
So I want to be able to load a SWF i made (which is not part
of the application) made with flex or flash.
The problem that i'm having is that if the loaded SWF adds
listeners to the stage or to it self, the listeners keep calling
functions even after the SWF was removed using unload or by loading
different content.
I've tried this with both AS3 and the flex framework and with
SWF's created in both flex (using the flex framework) en flash.
Setting the listeners with weak reference seem to work for
AS3 (Loader).
But this is missing the point, since i want to be able to
load just
any SWF file (Flash 9, AS3 offcourse).
Any help would be welkom

Well you have to ways to go arround this:
You can remove the event listeners when you unload the
movieclip from the SWFLoader, or you can impement an UNLOAD event
listener in the containing SWFLoader or the stage, the UNLOAD event
bubbles witch means that you'll be able to catch this event and
remove the listeners. Still, you'll have to know witch events the
swf has registered to, I haven't been able to find any function to
know witch events a specific object is listening to. I don't think
there is :(.
On the other hand any swf compiled with flash 8 or prev.
shouldn't have this problem since it will work in a different
virtual machine... still you wont be able to control them ether.

JComboBox listener problem

Hi all,
I have following problem, i use combobox and i need to write listener for selecting item.
But both ActionListener and ItemListener are unusable for me, because i dont know how to differ between selecting item when combobox is poped up.
I dont want to react on going thru items in popup, but only to FINAL select of button.
Please Help.
Mathew, HSIGP

     This works on non editable combo boxes
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;
public class ComboBoxAction extends JFrame implements ActionListener
     JComboBox comboBox;
     public ComboBoxAction()
          comboBox = new JComboBox();
          comboBox.addActionListener( this );
          comboBox.addItem( "Item 1" );
          comboBox.addItem( "Item 2" );
          comboBox.addItem( "Item 3" );
          comboBox.addItem( "Item 4" );
          // This prevents action events from being fired when the
          // up/down arrow keys are used on the dropdown menu
          comboBox.putClientProperty("JComboBox.isTableCellEditor", Boolean.TRUE);
          getContentPane().add( comboBox );
     public void actionPerformed(ActionEvent e)
          System.out.println( comboBox.getSelectedItem() );
          // make sure popup is closed when 'isTableCellEditor' is used
          comboBox.hidePopup();
     public static void main(String[] args)
          final ComboBoxAction frame = new ComboBoxAction();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.pack();
          frame.setVisible( true );
}
