Need help - The network adapter could not establish connection
hi, I installed sql developer on my standalone PC. I am unable to create a connection. The following error is shown when try connecting:
IO Exception: The network adapter could not establish connection.
Should i set some Environment variable? Is there anything else i need to download/install?
Please help...! I am new to this...user11937618 wrote:

You need to ask your network admin folk to check your PC and ensure that it is correctly configured for IP networking for your network - valid IP address, valid IP subnet mask, etc.
You can look at your existing IP configuration in Windows by opening a command console and typing the command "+ipconfig+".
Once that is done, you need to test connectivity between your PC and the database server. You need the IP address of the server for that and use the "+ping+" command to see if you get a ping echo response from the server.
If you configure your Oracle client software (e.g. +%ORACLE_HOME%\network\admin\tnsnames.ora+ ) to use a hostname and not IP address, you need to make sure that your PC's IP stack can resolve that hostname into an IP address. Once again the "+ping+" command can be used, but this time using the hostname instead. The output will show the IP address the hostname resolved to.
All these are basic networking issues - and have nothing really to do with Oracle itself. You first need to get the networking to work on your PC, before attempting to use Oracle client-server. -
The network adapter could not establish connection
I encounter a strange problem:
I use a java application compiled JDK1.3 to access Oracle 8.1.5 through JDBC driver class111.zip, everything is ok. But after I modify it to JSP and put this JSP into iPlanet Web Server to do same thing, the error message as title occur. Why?
Your any hints or helps are highly appreciated. Thanks.i had quite the same pb:
it was because when i was connecting to my db, i was using SQL plus and i didn't have to give the name of the machine, just user, pass and instance
but with the driver i had to give the name of the machine,
so check in Tnsnames.ora if you are giving the good machine name...
i don't know if it helps...

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,

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.lovingbarcelona wrote:
* Yep I get the same on the dev box.

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? -

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

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

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
Dermot.

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.
Escape character is '^]'.
^]
telnet> quit
Connection closed.
then a fail:
$ telnet localhost 1522
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
$
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.

The network adapter could not establish the connection with Oracle
I installed Oracle in my laptop (windows 2008), and install Hyperion 11.1.2, when I configure Hyperion, it pops up with "the network adapter could not establish the connection with Oracle"?
Hi,
This usually means that the connection details you have put in for Oracle are incorrect or Oracle can not be contacted.
Double check your configuration connection details and make sure you can access Oracle using them details.
Cheers
