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

RFC JDBC Exception Handling

Hello,
i have the following scenario:
RFC receiver adapter (synchronous) <> XI <> JDBC receiver adapter (to MS SQL-database)
Is it possible to catch JDBC-exceptions, e.g. "duplicate primary key" and pass it to the calling rfc adapter?
thanks for your help
Christian

Hello,
still my problem is the exception handling of the synchronous JDBC - call.
If an error occurs I get the error "no payload found" in sxmb_moni_bpe
I think this is a problem of where the error occur, in the SOAP header
In sxmb_moni i get the following Error:

The root cause of this exception is: java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
1. From Weblogic Admin Console, go to this Datasource and TEST the connection and see if it is connecting successfully. May be the Host/Port for the Oracle connection and username/password or SID name may be invalid or wrongly configured.
2. If you have any client to connect to this database like SQL Developer etc, try to connect to that db schema from this tool and see if this works.
3. One more thing. Check the Firewall settings and specially if the DB Port is open on the server where the database is running. In our Env, usually unless we open the port like for Oracle 1521, outsiders or other machines cannot connect to that database either from SQL Developer or from weblogic datasoures. So check for the port not open issues.
4. Last option is if the Network is down and not able to connect to that db server. Check with Network guys.

Jdev. Db connection - Io exception: The Network Adapter could not establish

Hi,
I installed Oracle 9i and forms 9i in my PC. Both are working fine including SQL.
Now i would like to use Jdeveloper. When i try to create a database connection "Io exception: The Network Adapter could not establish the connection" error returned.
My Db connection details are
Driver thin
host name harry
jdbc port 1521
sid oradb
where oradb is database name and harry is host name.
also i try to give the following details in Enter Custom JDBC Url option
jdbc:oracle:thin:@harryt:1521:oradb
But, i get the same error. So, can you pl. help me to fix this problem.
- Murali

The Network Adapter exception is caused because:
1. The database host name, port number, or database instance name is wrong.
2. The database TNSListener has not been started. The TNSListener may be started with the lsnrctl utility.
C:\>lsnrctl start

ERROR:DBCP borrowObject failed: java.sql.SQLException: Io exception: The Network Adapter could not establish the connection

Does anyone know what this error means?I have already installed Analyzer 6.5 on Win NT, on locally installed Tomcat web server and the oracle 9i database is on a solaris box.I think the problem is it is not able to connect to the oracle repository but I don't know how to fix it. Thanks,Haroon

Joe,
It may happen during testOnReserve, too.

That means the Oracle URL you supplied to the pool is incorrect forconnecting to the
DBMS you want. If the same pool definition works sometimes and sometimesnot,
then it's an oracle problem with rapid connection requests. Make the poolmake all it's
connections at startup, by setting init=max, and this shouldn't happen.

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.

I am running an application which is accessing Oracle database, it worked fine these days , but now it is showing the following error in the server like,
SQLException: Io exception: The Network Adapter could not establish the connection
This is the actual code setup
setERPDB("jdbc:oracle:thin:@sc221lh1-pb1.am.mot.com:1570:proa611","chefcs2erp","Dcfcs2Erp");please help me in this problem..
note:
oracle server machine is Solaris only..
thanks in advance...
regards,
Java@2007

Check this:
- ping sc221lh1-pb1.am.mot.com
- Is the port number correct, usually it's 1521 and yours is 1570.
What the exception basically says is that is cannot find the machine or connection is refused or something similar. Did you install a firewall recently?

Localhost linux java.sql.SQLException: Io exception: The Network Adapter co

I recently upgraded from Redhat 9 to Fedora Core 4, and am running an Oracle 9i on this machine.
Since this upgrade, I'm unable to connect from the machine itself to the db, using the JDBC thin driver. This worked on Redhat 9.
I'm also able to connect from any other machine to this db with the JDBC driver.
Also, any ping, tnsping, sqlplus work from localhost and other machines.
Only the JDBC connection from the localhost itself fails, with following exception:

EtherrealTake this with a grain of salt; I know a lot of the theory but don't have much hands on experience...
Not a bad idea, but you need to understand more if it's going to work (it might not). Etherreal and most other sniffers work by capturing traffic at the network interface (NIC) level, this allows the NIC to be switched into "promiscuous" mode and capture all the network traffic "on the wire" in that network segment, even traffic destined for other machines.
You can think of "networking" as an onion, or a stack of layers (see "OSI 7 laye model", Google or http://www.webopedia.com/quick_ref/OSI_Layers.asp for one theoretical approach), and etherreal works at pretty "outside" ot "low" level; the "internal" traffic that your interested in seeing either never gets to the level that Etherreal is monitoring, or is doing so in an area that is parallel to the one you're monitoring.
It's possible that you might be able to configure etherreal to see the "loopback" traffic. I suspect that somewhere, you can specify which network interface is to be monitored, and you can change it to monitor the "local" network interface. If your Linux setup is typical, etherreal is probably monitoring interface "eth0" and you probably want to monitor "lo" to see local traffic.
You can find out what interfaces you have with the command:
ifconfig -a
On the Red Hat Entrerprise that I have, that command is not in the default PATH, but is in /sbin; on other flavors of Unix I know it is found in /usr/sbin
If you can get etherreal monitoring the local interface, you should be able to see the traffic generated by "ping 127.0.0.1"
BTW, that command will also give you raw counts of the number of packets on all interfaces; if you have the machine to yourself, you might try a connection attempt and see which (if any) interfaces have packet numbers increase; if none do, then the connection attempt is failing before it gets to the packet level and Etherreal won't tell you anything.

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.

Dear all,
I have been trying to connect to Oracle 8 from Java but without success.
I am using the following driver: oracle.jdbc.driver.OracleDriver

Dear colleague,
I am using a stand alone database running on my windows 98 laptop.
I connect successfully via sql plus using the user id: scott and password tiger.
Below is the entry of my tnsname.ora:
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(CONNECT_DATA =

I am finding difficult to specify a host, but I have tried the following combinations:
DriverManager.getConnection ("jdbc:oracle:thin:@koudry:1521:PLSExtProc","scott", "tiger");
where the machine name is koudry and PLSExtProc the sid.
DriverManager.getConnection ("jdbc:oracle:thin:@localhost:1521:PLSExtProc","scott", "tiger");
and also 127.0.0.1 which is the ip address of the localhost. All these give me the following error:

Java.sql.SQLException: Io exception: The Network Adapter could't establish connection

Hi,
I run java application on one Sun Solaris (5.8) server and call Oracle 8.1.6 MTS database on another Sun Solaris (5.8) server.
When I am using jdbc:oracle:thin:@host:port:sid, I got:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection.
So, I changed to jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostip)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=databasename)(SERVER=DEDICATED))). It works.
But, when I tested java application with jdbc:oracle:thin:@host:port:sid on other Sun Solaris 5.8 server, using same classes12.zip and connect to same MTS database, all of them worked.
Right now, there is only one Sun server does not work with jdbc:oracle:thin:@host:port:sid format. And on this SUn server, using jdbc:oracle:thin:@host:port:sid format connect to other dedicated Oracle database is fine.
Thanks for your help advance.
Paul

This is going to sound stupid, but have you made sure that the server that couldn't connect resolved the name of the database server correctly? We had some problems with some of our field offices not correctly resolving the IP address for our server when the name was given. I would first try and put the IP address for the server/host name:
jdbc:oracle:thin:@1.1.1.1:port:sid
That's just a thought, hope it works for you.

actually I changed the hostname for plesk. when I restarted the server then error appears:
java.sql.SQLException: Io exception: The Network Adapter could not establish the connection
thanks & best regards

1) What is "plesk"?
2) java.sql.SQLException implies that you have a Java application using JDBC to connect to the database. That would seem to imply that this has nothing to do with ODBC.
3) When the JDBC driver raises this error, there should be additional information about what particular Oracle error was raised. Do you have that information?
4) Can you connect to the database using a different application? Like SQL*Plus, for example?
5) Taking a wild guess, I'd tend to suspect that you would need to change the host name configured for the client's connection string. That might be in your tnsnames.ora file, it might be in a n application config file, it might be in an application dialog, or that information may have been embedded into the application.
