What should I do? And when the server starts and I run the application, I get the following error:

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
Can anybody help me...?????
Can you try writing a testcase that allows you to connect to the database by going through JDBC ?

The Network Adapter could not establish the connection Error Code: 17002
Hi,
after upgrade b41 to b49, I get error from subject, without any changes in my app.
This occurs only on Oracle AS, on standalone OC4J application works OK.
I use connection defined in persistence.xml:
<non-jta-data-source>jdbc/MyAppDS</non-jta-data-source>
and can successfully test this connection in Enterprise manager.
Also, I tried all tricks mentioned here:
http://www.websina.com/bugzero/kb/oracle-connection.html
I know, that this is JDBC layer problem, but I am sure, that my connection is OK, and
after downgrade to b48 this problem fall away.

How have you deployed your application exactly, i.e. what is the structure of your ear. I use standard war for deploy.
Is the DataSource defined in your server, or your application? Defined on server, test on Enterprise manager passed successfully.
Try using a direct JDBC connection in your persistence.xml (driver/url), does this work?Not work, this same exception.
How do you access your entity manager? (managed, non-managed, jta, non-jta?)non-managed, non-jta.
FYI, I make downgrade to build 48, and this works - it is last version without this problem.
I added some tracing code to my SessionCustomizer:customize():
DatabaseLogin login = session.getLogin();
logger.fine("URL is :" + login.getDatabaseURL());
With build 48, connection defined using toplink.jdbc.* , the output is:

Io exception: The Network Adapter could not establish the connection
Hi All,
I run tomcat and connect to Oracle fine, both on the same machine.
I also run some batch processes daily and they often run without problems. The batch processes lots of selects and updates/inserts onto Oracle.
These tend to work fine, but sometimes when they run I get
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
So a batch process will be running doing lots of selects and updates then it just decides it had enough and throws this error each time it tries to connect. Meanwhile tomcat continues to run fine through the same TNS listener, but subsequent batch jobs fail to connect.I normally have to restart the TNS Listener.
I connect through the same class whether connecting through Tomcat or from the batch process with this:
public static Connection getConnection(String caller) throws SQLException{
try{
Connection con;
if (standalone){
try{Class.forName(driver);}catch(ClassNotFoundException e){}
con=DriverManager.getConnection(url,user,password);
return con;
}else{
if (ds==null)initialiseContext();
con=ds.getConnection();
return con;
}catch(SQLException e){
ds=null;
logger.debug("Problem in DBAccess.getConnection()...");
logger.debug(e.getMessage());
e.printStackTrace();
throw e;
I specifiy params such as MaxIdle with Tomcat using the xml config but not when its standalone - could this be affecting it?
Any idea?

Oracle should be able to handle lots of connections no problem, I agree, and it is through tomcat.
Yet the exception that you get says that it isn't. Oracle, for example, on a single box shouldn't be able to handle 100,000 simultaneous connections.
I would be very surprised if it couldn't handle 1,000. And if there was an issue at that point it would be a resource bound issue, like CPU (on the single box) rather than connections.
You suggested licensing issues?I believe at one time, not necessarily now, the Oracle server would be sold such that it limited the number of simultenous connections. This could have been a relatively low number. There are quite a few assumptions in that - the major one would be it is based on my faulty memory and second would be that it was years ago.
By the way you are not running this on a unix variant system without redoing the kernel limits to set up for a server system right? -

hi guys,

JDeveloper Oracle XE The Network Adapter could not establish the connectio
I installed JDeveloper 10.1.2 and oracle express on Fedora.
Now I cannot create a database connection from jdeveloper using the connection navigator
The hostname, port etc is correct.
Sqlplus and everything else regarding the database on the command line works fine.
Did I miss something ?
Maybe an environment setting ?
I did the following installation (all on the same host):
Java runtime
JDeveloper
XE Database
Testing a connection I used the Oracele Database Express Edition 2 Day PLus Java Developer Guide.
Is this documentation complete ?
Can someone also explain to me what the error message
Io exception: The Network Adapter could not establish the connection EXACTLY means ??
Where does it go wrong ?
Is there a checklist for thsi kind of thin-java connection problems ?Here some extra info, as I just said I did a default installation.
The listener is up on port 1521, see ouput:

"The Network Adapter could not establish the connection" error
I'm intermittently able to connect into my development database from my PC. When I'm not able to connect in, I'm getting a message of "The Network Adapter could not establish the connection" regardless of the client I'm connecting with. This database is located on a server and is Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production. I have a local install of WebLogic Server that has generated the error message when attempting to start. I have also received the message in SQL Developer and SQL Plus.
As I stated in my first sentence, the issue is intermittent this morning - sometimes I can connect and sometimes I can't...
I've been working successfully in this database for months now without this issue, so I'm guessing that the database itself is having issues, but I'm not a DBA...just a measly developer trying to use the database ;)
Are there good questions for me to ask of my DBA or ways to discover what could be causing the issue? Or, is there something I can do on my machine to get around this?!. Suggest contacting your DBAs first, but Id suggest seeing if the connection is up.
when you get it, check the tns connection. open a dos window
firstly tnsping the database name
tnsping <SID of database from your tnsnames.ora>
then try ping the machine where that SID is
then try telnet to the port of the database thats in your tnsnames.ora
telnet <host> <port>
if you get a blank screen then you know at least the listener is up and running on that machine. CTRL + [ will back you out of the telnet session. -

ashokAshok,
Your database connection URL doesn't look right to me. The default database connection listener port is 1521 (not 9200). You can check this using the "lsnrctl" utility.
To find the "host" and SID parts (of the URL), use the following SQL query:
select HOST_NAME, INSTANCE_NAME from V$INSTANCEGood Luck,

SQL error: Io exception: The Network Adapter could not establish the connec
Hi,
I am sure this question has been asked a million times and maybe i haven't searched the forum enough.
But here's the situation. I haven't used oracle too much. So I am not too familiar with data-source and what not..
I downloaded the latest version of oc4j(standalone) a few days back. I am trying to get the Oc4j j2eehome/demo/ormap to work .
I deployed the application manually by editing server.xml and http-web-site.xml files...
But i get this error
SQL error: Io exception: The Network Adapter could not establish the connection
I have no clue what that is..
I know its got to do with the bean not connecting to the Database. Do i need to download the oracle database server too.. The documentation says something about the cloudscape database.. Well basically i am lost..
Any information will be very helpful.
regards
-amitHi Amit --
This exception means that the container can't connect to the database instance to which it has been directed to use.
If you are using the ormap demo, then this is an entity bean based sample and will need a database.
The database configurations are stored at the server level in the j2ee/home/config/data-sources.xml file. In this file you will see entries that define a datasource using a set of "locations", provides details on where the database instance (host, port, sid) and what the logon details are.
For the container, a default-data-source is defined (ie one to use if no others are supplied) in the j2ee/home/config/application.xml.
<orion-application autocreate-tables="false"
default-data-source="jdbc/OracleDS">
To make it work simply, make sure that you have a datasource named jdbc/OracleDS defined in the data-sources.xml file (which should be there as a template) and that the connection details for it point to a valid database instance and user.

Java.sql.SQLException: Io exception: The Network Adapter could not establish the conn
Hello all!
First of all, I want to say I read all the answers to this problem that were posted in the past in this forum.
I try to connect from the intranet to an Oracle database, named bc01. The string I use is "jdbc:oracle:thin:@192.168.199.11:1521:bc01". On the 192.168.199.11 machine the listener and oracleservice services are started. The bc01 is correctly added to tnsnames.ora. If I issue a tnsping80 192.168.199.11 from the console it works. However, if I issue the same command from my workstation, it doesn't work (says No listener). So what am I missing here?
Any help is much appreciated !
Thank you very much!Faizan,
Normally this error is reported when the database is either not available or the URL is invalid. Please check the URL whether you have a valid DB connection there.
Also I see the getConnection missing e,g.
Connection conn = ds.getConnection();

I am trying to setup DataSource for my application and I am using oracle 8.1.6.3 database. I have following entry in the data-sources.xml file
<data-source
class="oracle.jdbc.pool.OracleDataSource"
name="jdbc/pool/OracleDS"
location="jdbc/ConnectionDS"
pooled-location="jdbc/pool/OracleDS"
url="jdbc:oracle:thin:@machine:1521:development"
username="user"
password="password"
min-connections="3"
max-connections="50"
wait-timeout="10"
inactivity-timeout="30"
/>
In my JSP code I am doing following to access the database
ResultSet sqlResultSet = null;
PreparedStatement stm = null;
InitialContext ic = new InitialContext();
DataSource ds = (DataSource)ic.lookup("jdbc/OracleDS");
stm = conn.prepareStatement(updtUser);
I got following exception when I ran teh code
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection

SamirHi,
according to the message, the database is not accessible. This can be because the database is down or the database connect information points e.g. to a wrong port

HOW TO RESOLVE(Test failed: The Network Adapter could not establish the connection)
Hii
I want to create new databse as sysdba in jdev.I followed the steps as given in
Oracle JDeveloper 11g Release 2 Tutorials - Designing and Building Database Tables
In step 7 create database user and database connection, I am not able to do that and getting the error
(Test failed: The Network Adapter could not establish the connection).
Please help me.Hi,
Could you please provide all value you pass to the connection properties on the connection creation panel? First of all, you should choose "Generic JDBC" as the connection type in order to use BDB SQL JDBC driver.
Regards,
Cindy -

Jdbc. The Network Adapter could not establish the connection. Help Please!!
I've found several responses over this issue, but none works for me.
I'm trying to setup a simple jdbc connection from a simple program.
Platform:
Fedora Core 4 (FC4) on AMD 64 bits
Java 1.4.2_04 (64 bits)
ORacle 10g or Oracle 9.2.0.4 (none works);
Tips:
- I can't connect to a remote server, nor to a local server
- I can connect using SQLplus
- TNSPing works fine
- Listener it's up
- my connection string is jdbc:oracle:thin:user/name@host:port:sid
- Also try jdbc:oracle:thin:user/name@//host:port/sid
- I'v tryied with classes12.jar, odbj14.jar
- my hostname it's ok.
I've monitored ip traffic on remote computer. While using TNSPING I detect activity. While using jdbc, no.
Please, any idea??Thanks for your reply.
To your questions:
- I´v tried both IP, host, and even host.domain
- I can connect from remote workstation using toad, and from local using sqlplus.
- I can´t connect via jdbc.
Folowing:
A) my sample code
B) the stack trace
C) the listener status (from my 9i server. Also tryied another servr with 10g)
when I call this program, I´ve tried severl connection strings:
jdbc:oracle:thin:user/pass@sdd51:1521:ebf
jdbc:oracle:thin:user/pass@:sdd51.sdd.com.ar:1521:ebf
jdbc:oracle:thin:user/pass@:10.10.10.51:1521:ebf
also try the other sintax:
jdbc:oracle:thin:user/pass@//sdd51:1521/ebf
In the classpath, I´tryied:
clasess12.jar
ojdbc14.jar
nls_charset12.jar
thanks

Top Link error 17002 The Network Adapter could not establish the connection
I have installed an application developped in an another environnement.
I have created the database schema in my own database.
I have created a database connection to this schema.
I have reconciled the schema using this connection (so the database and the connection are available and correct from jdeveloper)
I have updated the Mapping to use the new connection and new generated the mapping status report without any errors
and i still have this error ! The Network Adapter could not establish the connection when i access any jsp document containing data from the database.
I check and recheck everything and all is correct ... sure something is wrong somewhere ... where is the question ...Sorry I think you didn't read the thread or you read it too fast !
I'm not a beginner and I know what the problem is but all the settings are correct in jdev and the database and the listener are running ... i'm able to browse the tables, seeing data reconciling objects with the database connection referenced in the top link descriptor
It seem that top link is using something else and i don't understand from where it took the connection description. -
Hi, I'm running the following setup:
Mac OS X 10.8.4
Virtual Box 4.2.16 r86992
Oracle Developer Days (don't know the version, just downloaded it)
SQL Developer 3.2.20.09
Networking is host-only, I tried bridged but that doesn't make a difference for the problem at hand. I can ping my virtual box just fine, telnet to port 1521 looks good too:
$ ping 192.168.56.101
PING 192.168.56.101 (192.168.56.101): 56 data bytes

Connection closed by foreign host.
When I create a new connection with sql developer, with the same hostname / IP (192.168.56.101), Port 1521 (didn't change that) and SID orcl, basic connection type, it can't even connect, throwing the error mentioned in the subject:
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
I have looked at various threads in the forums here but I'm still stymied why the connection seems to be ok, yet sql developer has problems with it. If I create an ssh tunnel so sql developer only has to connect to localhost it works:
ssh -L 1521:192.168.56.101:1521 -l oracle 192.168.56.101

This may be of varoius reasons..
Is the database that you are connecting on the same PC?
You have specified Hostname: localhost.
If not please replace it with the IP of that server.
Else please check whether the database listener is started or not. if not please start the listener.
Check the SID by tnsping command.
Hope this will help you..
Thanks
Ashok
