Connecting to Oracle database in Java using TNSNAMES.ora

I have a program that can connect to both MSSQL and Oracle databases. It works fine when a user has defined an odbc connection, however if the user only has a tnsnames.ora, I don't know how to code the program in Java to connect to the database. I can't hard-code the server name because I don't know the database up front - I need to be able to read tnsnames.ora to get the information instead. How can I get this information? So far, the object OracleDataSource seems to be getting me the closest, however I am still failing to connect.

In 10.2, JDBC-Thin supports TNSNAMES entries lookup in tnsnames.ora, resulting in a much simplified and driver type independent Oracle Net descriptor. You must set the system property oracle.net.tns_admin to the directory that contains your tnsnames.ora file.
See the Oracle JDBC 10.2 doc.
Here is a code fragment from my book (see my blog below)
java -Doracle.net.tns_admin=$ORACLE_HOME/network/admin
or:
System.setProperty("oracle.net.tns_admin", "c:\oracle\net\admin");
OracleDataSource ods = new OracleDataSource();
ods.setTNSEntryName("tns_alias");
ods.setUser("scott");
ods.setPassword("tiger");
ods.setDriverType("thin");
Connection conn = ods.getConnection();

Hi,
I am trying to connect to the Oracle11g database server from the client machine using JAVA eclipse. I have installed the oracle client in the client machine. Once i try to execute the below code it was throwing below error:

OracleDriver drivers = new OracleDriver();
System.out.println(drivers);
Connection connection = null;
connection = (OracleConnection)DriverManager.getConnection(connectString,"ADMIN", "admin");
System.out.println(connection);
System.out.println("Connected to the database");

Using php to connect to Oracle Database 11g Release 2 Enterprise Edition EE

Greetings everyone!
Please i dont know how to connect to Oracle Database 11g Release 2 Enterprise Edition with php even though i connected with php successfully with Oracle Database 11g Express Edition with the php code below. can someone help please...Note im referring to oracle EE not XE.

if (!$conn) {

Edited by: user11273096 on Jul 15, 2011 12:03 AM

Find the hostname and service name of the database and use those values in the ORA_CON_DB constant.
Use 'lsnrctl status' on the database host to find the service name.
If you use a "tns" alias, you may need to create a tnsnames.ora file where PHP can access it.
Set the environment variable TNS_ADMIN (on Linux) to the directory containing the file.
See the section "Oracle Database Name Connection Identifiers" p 102 of the free book

Actually, there was a problem with my oracle client installation. I uninstalled it and then installed back again but still, even after following your instructions I get some error.
Here what I did:
Created tnsnames.ora file as below:

I Googled this error and tried to figure out what the problem is and came across the possible cause which is because I haven't specify that the service should run as a user who is in domain admin group.

do I really need to set this?

Note that this forum is for XE Beta, not EE.
Can you connect from some other client tool, such as sqlplus?
There's a {forum:id=178} forum that may be more suitable, if basic connectivity outside php works (i.e. issue is only php specific).

ODI topology connection error - oracle database

Hi,
I'm trying to connect to oracle database installed on a remote server through odi client installed on my windows machine. Oracle db is on RHEL 64 bit, I believe. I know the connection details such as hostname, sid etc but i'm not able to establish a connection using the oracle jdbc driver. I can perfectly connect to the db via sqldeveloper using tnsnames and also basic connection which rules out the possibility that i might be giving incorrect SID name in ODI connection since I'm using the same details for both
Error which i received is:

tnsping works fine. To solve the problem, I changed my JDBC connection string to another format which uses connect description with service name and that solved the problem. This is what I used.
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on) (ADDRESS=(PROTOCOL=TCP)(HOST=) (PORT=1521)) (ADDRESS=(PROTOCOL=TCP)(HOST=) (PORT=1521)) (CONNECT_DATA=(SERVICE_NAME=)))

DBA studio: Error add/connect database "Failed to parse tnsnames.ora file"

Also got this when I tried to manually add a database to a tree.
I can access the databases listed in my tnsnames.ora using SQL Plus with no error.
This is my tnsnames.ora.

Does anybody have any idea what is wrong? Thanks a lot. Changsong

Just found out this IS a string error in my Tnsname.ora. What i did is deleting all the entries in my tnsname.ora, and start adding each one back. I found one particular entry is responsible for the error. This is the old text
serv32.xxx.ge.com =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (COMMUNITY = TCP)(PROTOCOL = TCP)(HOST = sevr32.xxy.ge.com)(PORT = 1521))
(CONNECT_DATA = (SID = atmo32))
just looking by itself I can't see anything wrong. I just formatted it a little, making it looked like the other one that is working
serv32.xxx.ge.com =(DESCRIPTION =
     (ADDRESS_LIST =
     (ADDRESS =
     (COMMUNITY = TCP)
     (PROTOCOL = TCP)
     (HOST = sevr32.xxy.ge.com)
     (PORT = 1521)))
     (CONNECT_DATA=
     (SID = atmo32)))
and now it works fine. I Really can't tell the difference, except that some words were moved to the other line. What puzzled me is that the same old tnsname.ora worked in almost all the other circumstances, like sql plus, and other database enginee. But it is just not good enough for dba studio?
I admit I probably should have used the network utility to add a connection to avoid this type of format error.
Anyhow, I'm glad it is solved. by the way, the symjct.dll mentioned in the previous post should be symcjit.dll. I guess he mispelled the name. I renamed it to symcjit_old.dll and now the java error was gone. So that is another gain from this post. Thanks Joel for all the information.

Is the Windows firewall active? Have you enabled the port on the firewall, if it is?

Connection of oracle database in database server from application server

Hi,
I have two servers, one is application server and another one is database server…..
I want to connect oracle 10g database in database server to application server. In application server oracle 10g client is installed……In database server, I have set tnsnames.ora, Listener.ora …while checking in lsnrctl…the particular sid is running fine…
In application server, while I give as sqlplus
After giving username and password its showing error as
ORA-12545: Connect failed because target host or object does not exist
While surfing in net it shows check tnsnames.ora and listener.ora….. I have set the environmental variables here in application server…..
It’s connecting when I give
Sqlplus
Sql>username/password @ hostname: 1521/sid_name
Is it possible to connect with the username and password
I have set the host names in /etc/hosts….
If we are giving the hostname, port number and Sid name this connects without using tnsnames.ora…..
While pinging between two servers the connectivity is there between two servers…..
Could u pls help me out?
Thanks in advance

How to connect to Oracle database from webdynprojava application

Hi
How to connect to Oracle database from webdynprojava application. where can we provide the code to connect to database.?
Thank You.

Hi,
You need to create Java Bean model. The bean is a typical java bean with default constructor, getter and setter. You can have additional methods for query etc. The attributes in the class will be your model node and attributes.
However you need to configure the connection and create JNDI using visual administrator before writing the code.
You can also consider writing Session EJB with oracle and using them in WD.

Connect to Oracle database from SQL Sever

Can you help on an issue of connection from SQL Server to Oracle database:
In SQL Server, I create a "linked server" to connect to Oracle database on a different machine. But it will take a unreasonable time (about 30 seconds) to call a Oracle query from SQL Server.

No there are no entries required in the TNSNAMES.ORA
When you are using ODBC for connection, Oracle does not look fo rany enteries in TNSNAMES.ORA file.
Now I am able to connect to both SQL Plus and Forms 6i. But while connecting to SQL Plus its giving an error
Error accessing PRODUCT_USER_PROFILE
Warning: Product user profile information not loaded!
You may need to run PUPBLD.SQL as SYSTEM
Server not available or version too low for this feature
Connected to:
Oracle Open Client Adapter for ODBC 6.0.5.35.0
Microsoft SQL Server 08.00.0534
Also while disconnecting the Windows Program Error comes, and the application closes abruptly.
