JDBC+oracle+network adapter!!!

I have a jdbc program question:
the oracle jdbc example Employee.java,I can run it under (win2000+oracle8.05),but when I run it under
linux(redhat 6.2+Oracle8.16),the error show:"the network adapter can not estblish the connection",I can use the network adapter to ping other machines,and others can telnet this linux machine,I don't know what is wrong with the program or linux or network adapter or machine,If you can answer me,
I thank you from the bottom of the heart.

hi,
what dirver you are using?

UPDATE BLOB type with J2SE (JDBC ORACLE outbound adapter)

Hi all,
I'm trying update row into Oracle table with column type BLOB via XI 3.0, but it doesn't work.
Does anyone send me some sample of correct XML file, with update column type BLOB ?
Thanks
My test XML document :
?xml version="1.0" encoding="UTF-8"?>
<root>
<StatementName1>
<SAPXI_OUTPUT action="UPDATE">
<access>
<DGPODPIS >sdcfo2JTiXE=</DGPODPIS>

Hi !
I have make some test's today. I copy the adapter from our productive system P15 SP3 to the developers D15 SP6. Then we take the same message and send this from sap p42 to sap xi d15 sp5 to the adapter d15 (copy from p15 sp3) to the same Oracle database and it's working.
SAP P42 - Orders - XI D15 SP6 - Orders - Adapter D15 (copy from P15SP3) = it's working Record > ca. 800
I think we have a problem in the patch sp5.
We found also some different size in the adapter files.
This are the jar- files with different size:
SAPAdapterService.exe
adapter.properties
aii_msg_adapter.jar
aii_msg_runtime.jar
aii_rfcadapter.jar
aii_util_grmg.jar
aii_util_misc.jar
aii_util_rb.jar
inqmyxml.jar
lcrclient.jar
logging.jar
I make tomorow, a test with a adapter sp4.

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

I am not a DBA hence finding it hard to resolve the issue. Your help is highly appreciated.
Edited by: user3533384 on Jul 10, 2009 6:12 AM

Are you talking about the Enterprise Manager Console provided by the oracle or some other enterprise software? If it is enterprise software then you need to the do the proper setting for network connection to database. Probably you will have to configure tnsname.ora and sqlnet.ora. Can you connect through SQL*Plus utility? Go to Run-->SQLPLUSW type in the username password and tnsnames entry for the database. See if you can connect. If not post us the error message.

JDeveloper Oracle XE The Network Adapter could not establish the connectio

I installed JDeveloper 10.1.2 and oracle express on Fedora.
Now I cannot create a database connection from jdeveloper using the connection navigator
The hostname, port etc is correct.
Sqlplus and everything else regarding the database on the command line works fine.
Did I miss something ?
Maybe an environment setting ?
I did the following installation (all on the same host):
Java runtime
JDeveloper
XE Database
Testing a connection I used the Oracele Database Express Edition 2 Day PLus Java Developer Guide.
Is this documentation complete ?
Can someone also explain to me what the error message
Io exception: The Network Adapter could not establish the connection EXACTLY means ??
Where does it go wrong ?
Is there a checklist for thsi kind of thin-java connection problems ?

Here some extra info, as I just said I did a default installation.
The listener is up on port 1521, see ouput:

So still I dont known what is going wrong here, the following properties are used by this connection:
Type: Oracle (JDBC)
Driver: oracle.jdbc.driver.OracleDriver
User: hr
URL: jdbc:oracle:thin:@linux900:1521:XE
Is the driver used by JDeveloper correct ?
There is a note on XE that the use of oracle.jdbc.driver.* classes is deprecated but still supported.

Ashok,
Your database connection URL doesn't look right to me. The default database connection listener port is 1521 (not 9200). You can check this using the "lsnrctl" utility.
To find the "host" and SID parts (of the URL), use the following SQL query:
select HOST_NAME, INSTANCE_NAME from V$INSTANCEGood Luck,
Avi.

JDBC says: "The Network Adapter could not establish the connection"

Hi all! I'm trying to run a servlet that does SQL queries, but I keep getting a "The Network Adapter could not establish the connection" SQL exception on the connection attempt. Code follows.
import java.io.*;
import java.sql.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class InterpreteSQL extends HttpServlet
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException

               Class.forName("oracle.jdbc.driver.OracleDriver");
               Connection connection=DriverManager.getConnection("jdbc:oracle:thin:@labdb.dsi.unive.it:1521:lab","[my account here]","[my password here]");
               Statement statement=connection.createStatement();
               ResultSet res=statement.executeQuery("SELECT * FROM TabellaProva");
               stampaResultSet(res,response.getWriter());
          catch (Exception e)
               response.getWriter().println(e.toString());
// stampaResultSet method here, which would just print the result set.
Of course, the bits in brackets have the actual account and password in the code. ;)
If I make a standalone program with the same code, it works fine. I'm using Tomcat 4.0.3 on a Windows 98 machine. The machine is not directly connected to the internet, but through a router. There's a firewall but it isn't blocking the program. Since the standalone version works, I suppose it's a Tomcat configuration issue.
Can anyone help?

I too had the same problem
Check out for the related services. It must be running.
One way to know about is try using SQL+ and execute some query.Thats it.

JDBC Error - The Network Adapter could not establish the connection

Hi all,
I appreciate if anyone could help me out with my issue. I wrote simple java code on win 2000 to test whether I will be able to access Oracle 8i DB resided at some xxx.xxx.xxx.xxx machine within the network.
The code is:
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@111.111.11.11:1526:DBinstance","user","password");
The fist line here is executing and the problem is with second line of code. After executing this application from my DOS window, I am getting error:

I have installed Oracle client, where I can access the same database using SQL * Plus, but why I am unable to access the database from a Java Application? Do I need any web/application server to access it?
Any suggestions please?
Thanks,

I am sorry guys, I was using the port number as 1526, where I need to use 1521...

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 advance

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>'?

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.

How can i restore my connection.
Thanks

Hi,
According to the result of "ipconfig /all", the physical adapter dosen't appear.
Please check if the physical network adapter works properly. We can verify this in Device Manager.
To open Device Manager by using the Windows interface
Click Start, and then click Control Panel.
Click Hardware and Sound.
Click Device Manager.
If the network adapter is working properly, please make sure that the Internet Protocol Version 4(TCP/IPv4) has been checked in the properties of the physical network adapter.
If issue persists, please try to uninstall the Oracle Virtual box.
Best Regards.

IO Error: The Network Adapter could not establish the connection in oracle

Hi experts,
I have oracle developer days installed in my vitrual box machine. The connection to oracle datatase (11.2.0.2) contained in the oracle developer days was working fine via sql developer. I use eclipse to write some java programs to connect the database. However, somehow, I cannot connect the database via sql deveoper anymore. This is the error I got when I tried to connect it via basic connection type:
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Can anybody shed a light on this issue please. Thanks a lot in advance.

I, too, am running Oracle Developer Days inside VirtualBox.
On which system is SQL Developer installed?
The post errors indicate an OS/networking issue.
when was last time all worked without error?
what changed since then?

I have checked all the setups. Its as per document.
I will appreciate any help on this.
Thanks & Regards

Hi,
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,
Cindy

JDBC+oracle+network adapter!!!
