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
-amit

Hi 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.

Sql exeption: Io exception: The Network Adapter could not establish the connection

when i tried to connect to a oracle server using visual age for java i had this error message:
"java.sql.SQLException: Io exception: The Network Adapter could not establish the connection"
any ideas ...

if u r using think jdbc driver then check the Host name/address (IP Address) of the server and the SID and the port number.. there is no other reason for this.
Sometimes.. when the database is behind the firewall and the ports/IP is not open then due to denial of access this error occurs.

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();

Hi. This is definitely an oracle-only problem, so you should simplify the problem
down to a small standalone program using the oracle thin driver to make a connection.
Once you get this to work, weblogic will also be able to do it. Make sure that
when you try to have weblogic succeed after you can do it with oracle code only,
that the driver you used to succeed with, is ahead of any weblogic jars in
the server classpath. Note that we ship a classes12.zip in our packaging, but
Oracle has since released a newer one (with the same name!) that has some bugs
fixed. Make sure the later one is the one the JVM will pick up.

"You're not providing a lot of information here, but I'll assume a few

Ensure the URL param is set properly in the pool def. Check hostname,
port and database/TNS entry. Also, try dbpinging the database with the
following:
java utils.dbping ORACLE <user> <password> <dbname>
substitute the appropriate values where necessary. For example, I have
a TNS def called 'jforum.world' for a particular oracle instance. User
is 'auser' and the password is 'apass'. The following command will
test the connection:
java utils.dbping ORACLE auser apass jforum.world
Alternatively, you can try tnsping, an oracle util, to test the
connectability.
If either of these utils work, then it's probably a typo somewhere in
the pool properties.

SQL Developer Connection Error: Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection

Hi, I'm running the following setup:

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:

Hi Ali,
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

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?
Thanks.

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?

SQL Developer 1.5 - The Network Adapter could not establish the connection

I was using SQL Developer 1.2 until this afternoon. I saw that 1.5 was available so I decided to try it out.
Unfortunately, I cannot connect. I've tried connecting the same way I've done with 1.2 and it gives me the error:
"Io exception: The Network Adapter could not establish the connection"
No firewall changes, tns changes have been done the whole 10 minutes I was transitioning over from 1.2 to 1.5.
Any ideas how I can get 1.5 to connect?

Hi Echoi ,
1/Do you want us to look at the tnsnames.ora and see if we spot anything?
2/There are complications with existing ORACLE_HOME s:
Re: 1.5 not working at all for me
post from dooneill:
Hi Thomas,
SQL Developer does pick up the JDBC drivers from your local ORACLE_HOME.
To ensure your using the shipped JDBC drivers you could use the following small script.
I would appreciate if you could tell me if this works and what version of Oracle you have installed locally.
1) Close SQL Developer
2) Create a sqldeveloper.cmd file in the SQL Developer root directory
3) With the following contents
SET ORACLE_HOME=%CD%
start sqldeveloper.exe
4) Run sqldeveloper.cmd
Thanks

Failure-Io Exception:The network adapter could not establish the connection

Hi,
I am new to sql developer and need help regarding establishing connection in my PC.
I gave the following details for establishing connection.
Connection Name: DB
Username: myDB
passwd: xxxxx
Role: Default
Connection Type: Basic
Host Name: localhost
Port: 1521
SID: xe
When I tested the connection the following error occured:
Failure -Io Exception: The network adapter could not establish the connection
Please help me out.
Thanks in advance.

Some information showing:
How to check if there is something listening on a machine/port (there are also port scanners like nmap)
first a success: ctrl - ] typed in by me.
$ telnet localhost 1521
Trying 127.0.0.1...
Connected to localhost.

^]
telnet> quit
Connection closed.
then a fail:
$ telnet localhost 1522

Oracle also has tools to get the status of the 'listener' which is listening on the port, including database names for example 'lsnrctl stat' but it may have too many dependencies and privileges required to go into here.
If you do not have XE, you can install it with very few restrictions.

THis error usually means there is no network path to the database host, or there is a firewall in the way.
What details are you using in the connection definition?
Where is the database - on the same machine or on another machine?

Ashok,
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,

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.

JDBC Error - The Network Adapter could not establish the connection

Hi all,
I appreciate if anyone could help me out with my issue. I wrote simple java code on win 2000 to test whether I will be able to access Oracle 8i DB resided at some xxx.xxx.xxx.xxx machine within the network.
The code is:
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@111.111.11.11:1526:DBinstance","user","password");
The fist line here is executing and the problem is with second line of code. After executing this application from my DOS window, I am getting error:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:169)
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:211)

at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at DBConn.getConn(DBConn.java:15)
at DBConn.main(DBConn.java:40)
I have installed Oracle client, where I can access the same database using SQL * Plus, but why I am unable to access the database from a Java Application? Do I need any web/application server to access it?
Any suggestions please?
Thanks,
cs

I am sorry guys, I was using the port number as 1526, where I need to use 1521...
