You need to enable TCP services on SQL Server.

Java.sql.SQLException: The TCP/IP connection to the host has failed.

Hello. I hope you had a happy new year! Now its back to work.
I am having a problem connecting to a remote SQL Server DB. I am using NetBeans 5.5 and the latest J2EE. I am able to see the tables in the IDE and bind objects to data. But when I run it it gets this:
java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: no further information

I checked the SQL Server Configuration manager on that machine and TCP/IP connections are allowed. What else could be wrong?
Thank You.

"Connection refused" means that the client sends a packet saying "I would like to connect to port number NNNN please" to the server computer, and the server computer's OS sends the reply "there is no process listening to that port on the network interface you are using".
The database server is not running, or running but not listening to TCP/IP connections, or at a different port from what you think, or listening to only selected network interfaces (it is possible for a process to listen to a specific interface or a wildcard for all interfaces). A less likely scenario is that a firewall is sending the "connection refused" message.
First aid check list for "connection refused":
- Check host name in connect string.
- Check port number in connect string.
- Try numeric IP address of server host in connect string, in case name server is hosed.
- Are there any firewalls between client and server blocking the port.
- Check that the db server is running.
- Check that the db server is listening to the port. On the server, try: "telnet localhost the-port-number". Or "netstat -an", there should be a listening entry for the port. You need to configure the database to accept TCP connections; the server documentation or google should explain how.
- Try "telnet server-host-name the-port-number" from the client, to see if firewalls are blocking it.
- If "telnet" fails: try telnet with the numeric ip address.
- If "telnet" fails: does it fail immediately or after an obvious timeout? How long is the timeout?
- Does the server respond to "ping serverhost" or "telnet serverhost" or "ssh serverhost"?

The TCP/IP connection to the host has failed.

Hi everyone;
I have project with Java and Sql server 2000.My application server is Jetty.I work this tool successfully in Windows 2000 Server but I cant in XP Pro Service Pack 2.I take this message :
The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: connect
My Sql Server TCP/IP enabled and port 1433.There is problem here.Because I cant connect 1433.I tried this command.
telnet localhost 1433 .It is failed.I tried to open this port in firewall.Still problem is continue.
I am waiting for ur answer...

please help me by giving the solution.Help yourself by fixing the connection settings OR your network. The error is very clear: no connection can be made to the database. So what could it be? Wrong IP? A firewall is blocking you somewhere?
Nobody can tell you, you are the only one with access to your server settings and network environment.

ES2: The TCP/IP connection to the host has failed

A very simple error message appears against a stalled livecycle process which runs upon a flex form submission. You'd think that the connection to the server was lost.This custom process ("completion") is attempting to write out to the backend database at that time.
However,the "read" process to prepopulate the form already correctly uses the same JNDI connection. And that works. Every time.
The solution was to go into the "completion" process and move around the individual nodes, re-save and deploy again
Why is this - seems to be more problems in ES2 than we bargained for perhaps.

RemoteGui.bat Login attempt failed:connection refuse to SDM

Heloo Guru's,
I am trying to deploy service via running path: D:\usr\sap\XIG\DVEBMGS00\SDM\program <b>RemoteGui.bat</b> file .
I am giving password for SDM user but error coming on clicking login button
Error:could not establish connection to server <host> at port <50018>:connection refused:connect.
Please advise.

Hi Gaurav,
You can find the SDM configuration file in \usr\sap\<system_id>\<instance no>\SDM\program\config with file name sdmrepository.sdc. In this file you will find your sdm host name and gui port number (default 50018). You change it from here and restart the server if its not set properly.
Go to the mmc, select your serve node, expand instance 0 and look at the process table, you should have dispatcher / server0 and SDM nodes with their states set as started.
It is possible that SDM was kept in standalone mode and not started with your server. If that is the case
Run sdm jstartup "mode=integrated"
restart your cluster.
Regards,
Prateek

Mpd and pulse problem - Connection refused [SOLVED]

I'm having problems getting mpd to play nice with pulse-audio. Pulse is installed and works with vlc, mplayer, flash, etc. just fine. When I try to play through mpd the song in the gui simply shows a status of "paused" and the following gets written to the mpd.log.
Advice is appreciated.

The pulseaudio wiki suggests that a 'pulse' group and 'pulse-access' and even 'pulse-rt' groups may be required? I have used mpd for a year now with no such groups on my system.

TCP DNS Connection Refused

I am testing an application which uses tcp for dns.
My ActionTec router is set to "Medium" so it should allow all outbound connections.
When I use a dns server on my network all is well. When I try to use the ActionTec for dns I get connection refused with tcp requests but udp requests go through. I suspect the dns server on the ActionTec does not support tcp but I would like confirmation in case there is a setting I can change to make it work.
$ host yahoo.com
yahoo.com has address 98.138.253.109
yahoo.com has address 98.139.183.24
yahoo.com has address 72.30.38.140
yahoo.com mail is handled by 1 mta5.am0.yahoodns.net.
yahoo.com mail is handled by 1 mta7.am0.yahoodns.net.
yahoo.com mail is handled by 1 mta6.am0.yahoodns.net.
$ host -T yahoo.com
;; Connection to 192.168.1.1#53(192.168.1.1) for yahoo.com failed: connection refused.
Thanks,
AustinPowered

Keep in mind the ActionTecs are based around the dnsmasq lightweight DNS resolver if I remember correctly. If Verizon/ActionTec is using a version of dnsmasq older than v2.10, then it is a known limitation of dnsmasq to not support TCP queries. If someone can confirm what version the FiOS routers have, that would be great. This tool may be able to identify it:
http://netalyzr.icsi.berkeley.edu/
If you'd like me to analyze it, please send me a private message with the URL to your result, unless you don't mind your IP address being given out to the forums.

Decision Service calls failing with connection refused

Hi All,
Breifing of the bpel process - Async bpel process XX_BPEL_ASYNC_002 calls decision services and a sync bpel process XX_BPEL_SYNC_001.
We have moved to cluster 10.1.3.5.0 from 10.1.3.3.0 and the deployement of the bpel process and the decision service done on two nodes i.e., node51 and node55.
But the bpel process is able to call the decision service only when the node 51 is UP and running, but if node 51 is down and node 55 is up and running it is failing with connection refused error. It is also working when 55 is DOWN and 051 is UP.
the exact error is:
exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Connection refused.
We are using file based repository.
It is failing when it tries to call particular url:
http://loadbalancerurl:7777/orabpel/domain001/XX_BPEL_ASYNC_002/1.0/decisionservices.decs
Can anyone please help me or advice me for finding some solution.
Thanks

Hi Fatsah,
It has been a while since we resolved this problem. But these were the basic steps that we had taken.
The receiver was configured a File adatpter with FTP:
Port: 10021
Connection security : FTPS (FTP using SSL/TLS) for Control and Data Connection
Command Order: AUTH TLS,USER,PASS,PBSZ,PROT
Problem: The message was blocked in our firewall.
FTPS in this case used 10021 as the control port and the firewall allowed to pass the control request.
Once the connection was accepted at the control level, it generated a random port number to pass data on the channel.
This random port number was blocked in the firewall.
We monitored the data port numbers generated at firewall. Then we configured the firewall to open any port number between the specific IP addresses of the sender and the receiver. That resolved the problem.
Hope this helps!
Please give points if this is helpful.
Thank you.

The error is probably caused by the port number where the SQL Server is listening for the client connection.
If port number is different than the default number, you must specify the port number in the connection url
Also check the API for getConnection
[http://java.sun.com/j2se/1.4.2/docs/api/java/sql/DriverManager.html]
Connection conn = DriverManager.getConnection("jdbc:sqlserver://localhost:portnumber;username,password");

MSSQL's JDBC random connection refused

I am writing this app at home and my SQL server is at office (behind a router with SPI firewall, but i have port forwarded TCP port 1433 for the connection). If I telnet to SQL server, i wont get any error message but a blank screen, it looks like the server side is waiting for my console input.

SQL Server 2005 : connection refused

Hi,
I have installed SQL Server 2005 (Enterprise trial) on my PC,
then configured windows Admin Tools/ODBC DataSource.
I did not give a server name, so it picked up my computer name (OK-6400) as server name.
Created a DB called ZM there, a few tables, added some data, so it works fine through ODBC (with SqlDbx).
It never asked for port, so I assume it is 1433, am I wrong?
Now I need to connect to it through JDBC.
Tried several times through Eclipse (342) Database Development wizard.
1) With MSFT JDBC driver tried to use URL: jdbc:sqlserver://localhost:1433;databaseName=OK-6400/ZM
Tried with or without that server name:
"The TCP/IP connection to the host has failed. java.net.ConnectException: Connection refused: connect"
2) With JTDS driver URL: jdbc:jtds:sqlserver://localhost:1433/ZM - same connection refused
or with jdbc:jtds:sqlserver://localhost:1433/ZM;instance=OK-6400 -
- "java.sql.SQLException: Unable to get information from SQL Server: localhost."
Am I doing something wrong ? Please help !
(Haven't used SQL Server before)
Using Win XP.
Thank you,
Oleg.

I am not sure what is causing this. Any help would be appreciated.
Thanks in advance,

Hello Frank,
Thanks for your response. I checked the browser proxy settings in Jdeveloper, nothing is set there right now. Use HTTP Proxy Server is unchecked. What do I need to set this to?
