Iweb not establishing a connection
I am trying to upload my website to a ftp that has worked without a problem in the past. I keep getting a message that says it can not establish a connection. I have verified the information for the ftp and it is all correct. My hosting company has verified that the account is working. Why won't iWeb establish a connection if all the information is correct, and the hosting site is working?
If you follow Ethmoid's suggestion and find that the problem lies with iWeb and it's builtin FTP client you can try the following:
delete the iWeb preference files, com.apple.iWeb.plist and com.apple.iWeb.plist.lockfile, that resides in your Home() /Library/Preferences folder.
go to your Home()/Library/Caches/com.apple.iWeb folder and delete its contents.
Click to view full size
launch iWeb and try again.
If that does'nt work you may have to continue to use Cyberduck to upload your website files to your server. This tutorial may help in that situation: iW01 - Uploading Only Those Newly Published or Edited Files When Using a 3rd Party FTP Client

Hi
I have installed coheI have installed coherence server "fmw_12.1.3.0.0_coherence_Disk1_1of1.zip" along with Examples on windows machine and C++ client coherence-cpp-12.1.3.0.0b51709-windows-x86-vs2012.zip on the same machine.
I have built the "contacts" C++ Example successfully and while I execute this "contacts" using run I am facing TcpAcceptor error.
On my coherence server the TcpAcceptor is listening on port 8088, so I have modified the extend-cache-config.xml file with values "ip address of my windows machine" and port as "8088".
All the time I am getting below error,
coherence::net::messaging::ConnectionException: could not establish a connection to one of the following addresses: {10.242.152.242/10.242.152.242:8088}; make sure the "remote-addresses" configuration element contains an address and port of a running TcpAcceptor

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

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. -
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:

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? -
Error: The Network Adapter could not establish the connection
hi, i am using classes111.zip (the oracle 8.0.5 thin driver) with
linux and gnu jsp pages. the backend is an oracle 8.04 NT
database.
i get this error: "The Network Adapter could not establish the

Hi,
Iam new to using Oracle please help me in this problem. Iam trying to connect oracle8i in my home pc(win 98) in java.. I have said..
String url="jdbc:oracle:thin:@testhost:1521:sid";
DriverManager.getConnection(url,"scott","tiger");
Actually i have added the service name using Oracle Net 8 Assistant ... it asked me service name so i gaved "fobjects". then host and port number then i gave "testhost" and port number as 1521. then i tried to use the test service but i couldnt get it... it gaved me error called " ORA12545- Connect failed because target host or obejct doe not exist ..Even then i pressed finished button to accomplish the thing...ans when i executed the java program with the above service name setup it said SO Excpetion : Network adapter could not establish the connection.
Well What the wrong i have done, help me...

Network adapter could not establish the connection oracle 11g
Hi All,
I Have oracle 11g database in remote system.When I am trying to access through my Oracle Jdeveloper in my system,I am getting this error:
"Test Failed: network adapter could not establish the connection oracle 11g"
I also checked the ipaddress and listener status by giving lsnrctl status and service in remote system.Both are running.
What Should I do now?
Thanks in advance902286 wrote:

For starters, you make sure that there is even the possibility of a network connection between your client machine and the machine hosting the "remote system". What happens when, on the client machine, you issue a 'ping <ip address of remote system>'? -
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. -

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

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

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.

then a fail:

$
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.
