by the way I am able to connect with sql*plus ... lsnrctl gives the lsnr so thats running... tnslsnr is also running...also installed the latest java sdk i.e 1.5... i have set new path to point to this new java.exe i.e 1.5 one... this is really crazy and havent see such probs in any tools i have ever used and that too using it in normal pc ...

I've had the same problem when I installed the latest version of SQL developer (1.2.1.32.13) on a machine that still had an older, working version. My problem went away when I changed from an IP name to an IP address. on the connection setup window.

Network Adapter could not establish connection during installation

Hi,
I'm trying to install html db v10.2.0.1 and http server on the Fedora Core 4 platform and am getting a "Network Adapter could not establish connection during installation" error. This occurs after pressing Next at on the Specify HTML DB Database Details dialog box. Note that I'm not new to oracle databases or html db. I can't seem to find a similar thread on this forum related to the html db v2 install and I've read the FAQ related to the installation, making sure that I unset the TNS_ADMIN and ORACLE_HOME environment variables before launching the installer. I also checked that I can connect to the database via the listener, sqlplus sys@database as sysdba. I checked the listener status:

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...

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.

Network adapter could not establish connection

I get this error on WLS 6.1 SP2 and WLI 2.1 SP1. This is the scenario. I have
two instances of Weblogic installed on the machine. I first start oracle then,
I bring up the first server run an application and then shutdown the server.
When I try to start the second server, I get this error when the server tries
to make an Oracle database connection.

I too an recieving an error when trying to connect to Oracle 8.1.5 with the thin drivers.

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...

Network adapter could not establish a connect from external server

hi,
I've set up a jdbc thin driver properly using
the following input:
"jdbc:oracle:thin:@ipaddress:1521:DBname",
"username", "password"
When outside users try to connect externally (outside the network) there is a different ipaddress. Although they are able to ping,
telnet, run jsp etc... using the external address, they get the following error when they try the thin driver connection:
i/o exception: network adapter could not establish a connection
They change the ipaddress in the connection string to match the external ip. We are using oracle 8i, JRun on Linux. I have a feeling it has something to do with the tnsnames.ora file but I can't be sure.
Any ideas?
Thanks in advance!

this is expected behavior ...
the jdbc thin driver requires the use of an ip address that the calling program has acces to ...
internally you have one ip address exposed.
apparently you have another ip address set up for the external customer.
fyi
jdbc thin driver don'ts use the tnsnames.ora file -- they use "host:port:sid" because they are required to be platform independent and not access local datafiles or environment variables on the execution platform.
jdbc oci drivers do use tnsnames.ora which provides the host:port:sid info in their entries.

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.

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:
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:

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

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

Failure-lo exception:The network adapter could not establish the connection

Hi All,
any one can assist me .
I installed latest SQL developer in my home laptop
I am trying to connect using my SQL developer using my database UN and PW.
It is giving the following error message
Failure-lo exception:The network adapter could not establish the connection
Thanks in advance.
Regards,
Veera Lenin

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?

Failure -lo exception: The Network Adapter could not establish the connecti

I get the following error when I attempt to connect:
Failure -lo exception: The Network Adapter could not establish the connection
I'm running 64-bit Windows XP Pro. Is that possibly an issue? I can ping the server. I am going to go now and install Oracle client software, to see whether I can tnsping and then connect from that.
The remote listener is up and running. I did check that.
What else might be the problem?

Kris,
I don't mind having to re-key connections between versions of Raptor, but if Raptor is going to save a connection that worked when I entered it, I expect that connection to work when I restart Raptor.
If you can't save a connection with just the TNS Alias, at least save it as something that works - convert it to the basic format.
Having said that - I would certainly prefer the connection to be saved as the TNS Alias if it could be. We have in the past had cases where we have modified the SID or Listener Port behind a TNS Alias to reduce downtimes during upgrades. With a centralised TNS Names file (which we have), there is only one place to update - if we are saving the full details behind the connection on every developer's PC, there is then a lot of additional places where the details need to be changed.

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?
