TNS: No Listener on Oracle 10g Express Edition

I have installed oracle database 10g Express Edition but get a ORA-12541:TNS:no listener exception when I try to connect to the database. I can connect using SQL plus.
My listener.ora file looks like this:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP)(HOST = IBM-T8OGB066772)(PORT = 1521))
DEFAULT_SERVICE_LISTENER = (XE)
When I run LSNRCTL STATUS to check the listener status I get:

It seems the TNS listener has not configured correctly.
I have tried re-installing but have no luck. Can anyone help with that the listener.ora file should look like?
Many thanks,

Network issues in Windows, and the impact on Oracle install in general, are discussed here:
http://download-east.oracle.com/docs/cd/B19306_01/install.102/b14316/reqs.htm#BABIAEEC
Bottom line - you will need to come up with a useable & consistent IP address (from the loopback adapter, usually you use 127.0.0.1). I'd suggest, then you reinstall XE to use that IP address, get it working locally, then use the Application Express screens to 'enable it for the network'.
XE has it's own forum. Needs separate registration and needs you to sign in to the forums (daily) to see it after registration. This has been discussed in detail many times in that forum. Registration is at http://www.oracle.com/technology/xe/registration and this link Oracle Database Express Edition (XE) will get you there after signing in again.

Oracle 10g express edition browser login problem

Hi
I installed oracle 10g express edition and after installing successfully logged in browser , unlocked hr login and also created one form then I shutdown the database and rebooted my pc and since then when I try to login to "go to Database Home page" after starting database , I get a cookie 127.0.0.1 with username and password, First of all I am not sure what username/password it is expecting, I believe it requires my Windows XP username and password , I tried to enter couple of times my pc login username which has administrator privileges, I also checked it has ora_dba group but after entering pc username , password browser opens saying "unauthorized". I created another os user and tried with that still same. I tried entering oracle password "SYSTEM" and password for it but still could not login, I tried HR username password still nothing.
I tried disabling firewall but still same issue. I tried to re-install two time but still same .
Start database dos prompt does show all the process are started successfully .
I also did ping for 127.0.0.1 and it does ping.
I tried everything what I knew.
Can anyone please help me ..to resolve this issue .

Hi
This is how I resolved the browser login problem .
I checked the listener log
C:\OracleXE\app\oracle\product\10.2.0\server\NETWORK\log
And found the error
TNS-12542: TNS:address already in use
TNS-12560: TNS:protocol adapter error
TNS-00512: Address already in use
I have another version for oracle installed on my pc .
I ended both the oracle process (Oracle.exe) through the Task Manager
Then manually started OracleServiceXe service through Component Services
Control Panel Performance & Maintenance Administrative Component Services
Then did following
Programs Oracle Database10g ExpressEdition Start Database
Programs Oracle Databse10g ExpressEdition Go to Database Homepage
Enter username SYSTEM
Enter password xxxxxx whatever given at the time of installing.
And I did successfully login to the browser .
Hope this will help to those of you who have run into similar problem which I faced
Good Luck .

1) which Linux(freeware) flavor should I install ?Ordinarily, I'd recommend getting Oracle Linux (http://eDelivery.oracle.com/linux) because the default install includes all the prerequisite RPM packages you will need. And failing that, also offers another RPM package "oracle-validated" which will cause the installation of the necessary prerequisites.
But... you mentioned customer: if this is a revenue-producing situation and customer money is at stake, I strongly recommend they obtain commercial O/S support with either Oracle, Red Hat, or maybe SuSE/Novell. Compared to the cost of a downed business, an O/S support arrangement is cheap, cheap, cheap.
2) is there any virtual enviornment available for Linux Os on which I can install 10g Express Edition database ?Sure. You can run Oracle VirtualBox on most Linux, Windows, or Solaris boxes. http://VirtualBox.org for info.
3) If available, is there any difference in using the Linux Os in Virtual enviornment and actual installing Linux ? will there be any difference in installing database and configuration for both the cases?No real differences in either environment.
4) need download link for latest version of Red Hat Linux setupWhat, you didn't try http://eDelivery.oracle.com/linux yet?

Java Connection Pooling issue with Oracle 10g Express Edition

Hello
I have a Java based web application that uses the Oracle 10g Express Edition database. I am using a connection pool to get connections to the database.
I use the NetBeans IDE and run my web application on the bundled Tomcat server(5.5.7) that comes with the IDE. Though when I initially run the application from the IDE, the connection pool is set up fine, when I recompile my java code and try to run the application again, I get the following error each time:
Listener refused the connection with the following error:
ORA-12516, TNS:listener could not find available handler with the
matching protocol stack.
The logs before the error shows up, indicate that the connection pool object is fine and gives me the number of available connections and the number of active connections and so on, which I have printed from the constructor of the Connection Pool class:
For e.g.:
Cache size = 17
Available Connections = 17
Cache Limit = 1000
Active size = 0
However, if I kill my Tomcat server process and run the application again, it works fine with no error.
I looked around for possible causes and solutions and all I could find
was increasing the processes parameter value in the init.ora file. I have increased the parameter value to from 100 to 20000 now, in increments of 500/1000 each time but it hasnt worked so far.
Someone else suggested that I increase the size of my connection pool; I initially had it set to a minimum limit of 5, an initial limit of 10 and a maximum limit of 1000. However if I set the Initial Limit to anything above 17 connections, I see the following log on the Bundled Tomcat log and my application doesn't run at all:
Log: Loading JDBC Driver : class=oracle.jdbc.driver.OracleDriver ...
Log: Loaded JDBC Driver
Log: Connection with URL=jdbc:oracle:thin:@localhost:1521:xe as username/password
Error code not handled : 0
Exception Message :java.sql.SQLException: Listener refused the connection with the following error:
ORA-12519, TNS: no appropriate service handler found
The Connection descriptor used by the client was:
localhost:1521:xe
// End of log
And the Bundled Tomcat server automatically shuts down.
Again the System.out statements from the Connection Pool class constructor show that the cache has been initialized and that currently there are free connections available in the pool.
E.g.
Cache size = 18
Available Connections = 18
Cache Limit = 1000
Active size = 0
Has anyone faced anything similar? Could someone please suggest what I'm doing wrong here and what I should do to set right this problem?
Swetha

hello, please pardon me, my english is basic. i do of my best. i had the same problem until reading the pdf documentation 2 days for java devvelloper.it is simple, follow this way.
try {OracleDataSource ds;
Connection conn;
ds = new OracleDataSource();
ds.setURL("jdbc:oracle:thin:@localhost");
conn = ds.getConnection("userid","password");
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
don't forget to Dowload the user client of oracle Express Edition. do the rest of your program and it will work. take a look to the documentation pdf for java develloper. all it is explained. good look

Connecting oracle 10g express edition to jdeveloper

I am having all kinds of problems connecting oracle 10g express edition with my jdeveloper 10.1.3.3. I can query the database from my command line so I know it is set up, but for whatever reason jdeveloper will not connect with it. When I try to connect with the database through jdeveloper here is the error I keep getting:

Please any help would be appreciated I have been at this for days, thanks.

This has to be some kind of bug with 10g express because I see lots of people having similar problems. I'm in the process of uninstalling 10g, and I will re-install it see if that makes a difference. Again if anyone has any other ideas please keep them coming because this is utter BS it shouldn't be this hard.

Can not connect Oracle 10g express edition from report builder.

I have newly installed report builder . Different home was selected for Report builder and oracle. Oracle database server is also in the same machine. But i am not able to connect my oracle 10g express edition database. It throws error ORA-12154 : TNS could not resolve service name.( same error displayed while trying to connect from SQL Plus).But from toad i am able to access the database. May be because here I am able to select the proper home.
Here i am adding my tns entry

(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 1ECA66A679AB494)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
can any one suggest what the actual problem is?
Thanks ..........

Hello,
Oracle 10g XE is rather specific and, I'm not sure that you can upgrade it to 10.2.0.4 .
However, Oracle published an Upgrade Guide for Oracle Express Edition but, it's limited to *10.2.0.3*:
http://download.oracle.com/docs/cd/B25329_01/doc/server.102/b32391/toc.htm
But be careful:
Once you have upgraded to Oracle Database 10g, you cannot downgrade back to Oracle Database Express Edition.Hope this help.
Best regards,
Jean-Valentin

Issues during reinstallation Oracle 10g express edition and Forms 6i

I've been racking my head over this issue for the past two three days. Exasperated, I tried searching in the forums but could not find a specific scenario like this.
I am facing issues while trying to get forms 6i to work with oracle 10g Express edition
i have windows XP home edition (installed service pack 2) and installed oracle 10g express edition as well as the oracle 10g express client and SQL developer on the same machine. The database started fine and I was able to use Enterprise manager.
After that I tried installing Forms 6i and whatever i try i am not able to connect to the database from Forms though I was able to connect easily from SQL developer. I used to get the error 12154 "TNS:could not resolve service name"
I dont know if Forms 6i expects the database connector string in some particular format. I searched on the net and found some people solved the issue by reinstalling the database software.
My machine name was complex so I changed it as well and reinstalled the software. Again the DB was fine and connections were fine but no way I could get forms to connect to the DB. All the time
I tried installing Forms to the same folder that Oracle express edition home in the hope that it might fix the problem. That only caused my database to crash. The oracle xe service shows as started but the Enterprise manager link does not work and it seems the database is down. I tried uninstalling and reinstalling client and server to no avail.
Has anyone gone through such a situation and solved this ? Appreciate your help.

The statement about XP Home is correct, but in this case I would say the initial problem (Forms and ORA-12154) is independent of that, it also happens in a supported environment. I think it's the old problem, a second Oracle home was installed, but tnsnames.ora containing the connect informations is located in the first home.
Either tnsnames.ora is copied from to <Second_ORACLE_HOME>\network\admin or the environment variable TNS_ADMIN is set system-wide to <First_ORACLE_HOME>\network\admin.
I think now it's necessary to create a clean machine (remove all Oracle components as explained in the database installation guide for Windows). Then repeat the installation , but XE and Forms 6i in different ORACLE_HOMEs.

i want one more instance of database.Can you perhaps explain why? I have a fair share of production and development servers - and not a single one of them needs to run more than one database instance.
So I'm interested in what requirement you are trying to satisfy by using two database instances on a single platform.
Oh yeah - if you want to create a custom XE instance (different SID, different tablespace sizes, more/less PL/SQL stuff installed, hack standard), make a copy of your XE db creation script (in your XE's +$ORACLE_HOME/bin+ and called createdb.sh ) and modify that for your needs.
PS. even with a different SID, only a single XE instance can be run at a time - you can however have 2 different ones defined and then use one at a time (e.g. testing international settings, init param differences, etc.)

I'm an Italian university student and I have to make a presentation about Oracle 10g Express Edition for an exam. The points of this presentation will be:
- Portability
- Compatibility with SQL92 standard
- Interfaces
- Installation and hardware resources
- Costs and license
- Security
- Performance
I'm very new in the Oracle world, can anyone help me or suggest sites where I can retrieve the information I need.
Thanks

Si offende qualcuno o semplicemente capisce meno gente? Penso più la seconda, ma mi sembra più "educato" usare l'inglese, in modo che tutti capiscano.
Translation :
I think it would be more correct using English, so that everyone can understand.
