I want to connect Oracle Database use JDBC2,but...

I get this error :
Error in connecting Database java.lang.classNotFoundException:Oracel.jdbc.driver.Oracledriver.
My code only one sentence:
Class.forName("oracle.jdbc.driver.OracleDriver");
My classpath like this :
set classpath=c:\jdk\lib\classes12.zip
Platform:Windows 2000,JDK 1.3.0
Why?How do I do?

You have to catch the errors, totherwise it gives you compiling errors.
include this in your program for Class.forName:
catch(ClassNotFoundException E)
System.out.println("Error:"+E.getMessage());
include this for DriverManager.getConnection
catch(SQLException E)
System.out.println("Error:"+E.getMessage());

JD3.* could connecting Oracle database 5.05 but not new version

Dear Sir,
JD3.* could connecting Oracle database 8.05 but not new version of Oracle_Database at all(8I and 9I in OTN version), but could run on Borland JBuilder.
Error message : IOException
Could you tell me, help me too.

(This week in Openworld and and email: [email protected])

Steve -- My guess would be that you need to upgrade your JDBC drivers for your client program. They are downloadable from OTN. I expect that JBuilder has its own JDBC drivers which are newer than what you have and that is why it does not have a problem.
Thanks -- Jeff

How to connect Oracle database using C/C++ on Mac OS X PPC G4, XCode 2.4.1?

Hi All,
How to connect the Oracle database using C/C++ on Mac OS X? I have used Instant Client library "instantclient-basic-macosx-10.1.0.3" provided by the Oracle but could not be success. I'm using PowerPC G4, Mac OS X 10.4.9, and XCode version 2.4.1.
Specially Mr Oscar Armanini has done this in C on Mac OS X. Please let me know. I would be very thankful to you.
Thanks,
Ghufran

Hi Ghufran

How to Install, Configure and Test Oracle 10g Instant Client Basic,
SQL*Plus and SDK Packages for Mac OS X
(Runs OCI sample code - cdemo81.c)
https://metalink.oracle.com/metalink/plsql/showDoc?db=NOT&id=332588.1
How to Install, Configure and Test Oracle 10g Instant Client Basic,
SQL*Plus and SDK Packages for Mac OS X
(Runs OCCI sample code - occidml.cpp)
The first Metalink Note uses an OCI examples and it is pasted here below,
in case you don't have a Metalink ID.
The second Metalink Note uses an OCCI example.
I have never used Instant Client (neither on Os X or on other platform),
but I was successful on compiling C programs (no GUI involved) using the
Full Client installed on my PowerBook G4.
I'm a DBA, but I was a developer years ago (about when Oracle 7.3
was considered a giant step forward): I installed the Oracle 10.1 db
(a complicated job for a developer) and I got the Full Client
installed as well, for free, so I was happy to compile one of the demo C sources
(those that you can find in the Oracle Pro*C manuals:
by the way, Oracle Pro*C manuals are really worth reading).
Good luck
Oscar
Applies to: Oracle Server - Enterprise Edition - Version: 10.1.0.3
Apple Macintosh PowerPC
Goal
This article will show you how to install and configure your 10g Instant Client (IC) Software for the Mac.
It will install the following packages:
the Basic package
the SQL*Plus package and
the SDK package
and then test its connectivity to an Oracle database using SQL*Plus.
It will also show you how to setup and test a sample program, cdemo81.c, that uses the Oracle Call Interface (OCI)
to connect to the database.
The sample program is located under the <Instant_Client>/sdk/demo directory.
Solution1. Download the following three (3) files from the Oracle Technology Network (OTN) website.
You will need an account to do this.
Macintosh OS X 10g Instant Client Software
a. instantclient-basic-macosx-10.1.0.3.zip (32,395,622 bytes)
b. instantclient-sqlplus-macosx-10.1.0.3.zip (326,740 bytes)
c. instantclient-sdk-macosx-10.1.0.3.zip (293,913 bytes)
NOTE: The above three (3) files will be updated as new patches are released for the 10g Instant Client software. 10.1.0.3 or later versions (10.1.0.x) of these files may be used similarly with this article.
2. Save the following text into a file called tnsnames.ora:
# If you receive an
# ORA-12154: TNS:could not resolve the connect identifier specified
# error when running the setup script and attempting to connect to Oracle
# from SQL*Plus then the name of your SERVICE NAME (i.e. ORCL) may require
# that you include the DOMAIN (i.e. US.ORACLE.COM) in order to connect successfully.
# To obtain the DOMAIN of your environment, type "hostname" from your shell
# and it should report this information back to you. Configure your SERVICE
# NAME to look like Example 2.
# Example 1
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = database_machine.us.oracle.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = orcl)
# Example 2
#ORCL.US.ORACLE.COM =
# (DESCRIPTION =
# (ADDRESS = (PROTOCOL = TCP)(HOST = database_machine.us.oracle.com)(PORT = 1521))
# (CONNECT_DATA =
# (SERVER = DEDICATED)
# (SID = orcl)
3. Save the following text into a file called sqlplus_script.sql:
SELECT user FROM dual;
SELECT sysdate FROM dual;
SELECT 'successful ' AS TEST_RESULTS FROM dual;
exit;
4. Save the following text into a file called setup1:
# ===========================================
# MAC OS X INSTANT CLIENT 10g SCRIPT - SETUP1
# ===========================================
# DESCRIPTION
# ===========
# This script will install and configure your 10g Instant Client (IC) Software
# for the Mac. It will install the Basic, SQL*Plus and SDK (OCI/OCCI) packages
# and then test its connectivity to an Oracle database using SQL*Plus.
# Once this script has completed, you will need to run the script SETUP2 to build
# and run the CDEMO81.C sample application located under the <IC>/sdk/demo folder
# in your newly installed Instant Client home.
# NOTE: In order for this script to run successfully, you MUST perform any
# necessary actions required under the SETUP section below.
# SETUP
# =====
# (1) You MUST be in a directoy with ALL of the following files

# 2 - instantclient-sqlplus-macosx-10.1.0.3.zip
# 3 - instantclient-sdk-macosx-10.1.0.3.zip
# 4 - tnsnames.ora (configured properly)
# 5 - sqlplus_script.sql (connectivity test)
# 6 - setup1 (this file)
# 7 - setup2 (will run this file later)
# (2) Edit the TNSNAMES.ORA file and update it with the necessary information
# to connect to a database on your network. Be sure to note the comments
# in this file. You will have to change the following information:
# SERVICE NAME (orcl or orcl.us.oracle.com)
# HOST (database_machine.us.oracle.com)
# PORT (1521)
# SID (orcl)
# (3) Go to the end of this scrip and modify the following line:
# ./instantclient10_1/sqlplus scott/tiger@orcl @sqlplus_script.sql
# Replace "orcl" with the SERVICE NAME you used in step (2) above.

5. Save the following text into a file called setup2:
# ===========================================
# MAC OS X INSTANT CLIENT 10g SCRIPT - SETUP2
# ===========================================
# DESCRIPTION
# ===========
# This script will build and run the OCI sample application CDEMO81.C inside
# your Instant Client (IC) software located under the <IC>/sdk/demo folder.
# NOTE: In order for this script to run successfully
# (A) you MUST have already run the script SETUP1 successfully
# and
# (B) you MUST perform any necessary actions required under the SETUP
# section below.
# SETUP
# =====
# (1) You need to edit the CDEMO81.C application PRIOR to running this script to
# change the connection information. By default, the application will attempt
# to connect as user SCOTT with password TIGER to a local Oracle database using
# the BEQ-LOCAL network protocol. This will not work.
# (A) You need to make sure you have the SCOTT/TIGER schema created in your database.
# If not, have your DBA create it by running the script "SCOTT.SQL" from your
# <ORACLE_HOME>/rdbms/admin folder.
# (B) You need to modify the CDEMO81.C application to connect to the database
# you have configured inside your TNSNAMES.ORA file.
# (i) Open the CDEMO81.C file located under the <IC>/sdk/demo folder.
# (ii) Find the following line of code:
# (void) OCIServerAttach( srvhp, errhp, (text *)"", strlen(""), 0);
# and change the two empty strings to the SERVICE NAME you are using like so
# (void) OCIServerAttach( srvhp, errhp, (text *)"ORCL", strlen("ORCL"), 0);
# (iii) Save the file.
# (2) You MUST be in the initial directory where you copied all of the files listed
# in script SETUP1. In this same location you will find SETUP2. Run SETUP2 from
# this location.

6. Take all seven (7) files and move them into the same directory on your OS where you want to install the Instant Client software from:
1 - instantclient-basic-macosx-10.1.0.3.zip
2 - instantclient-sqlplus-macosx-10.1.0.3.zip
3 - instantclient-sdk-macosx-10.1.0.3.zip
4 - tnsnames.ora
5 - sqlplus_script.sql
6 - setup1
7 - setup2
7. Open the file tnsnames.ora. Be sure to review the comments in this file. You will have to change the following information to connect to a database on your network:
SERVICE NAME (orcl or orcl.us.oracle.com)
HOST (database_machine.us.oracle.com)
PORT (1521)
SID (orcl)
Save the file.
8. Open the file setup1, go to the end of this script and modify the following line:
./instantclient10_1/sqlplus scott/tiger@orcl @sqlplus_script.sql
Replace orcl with the SERVICE NAME you used in Step 7 above. Save the file.
9. You are now ready to install the 10g Instant Client software for Mac OS X. From the location where your seven (7) files reside, issue the following command:
[macosx]/oracle> . setup1
NOTE: Be sure to include the period "." and a space " " before the word "setup1" so all environment variables persist for the current session.
This will install the Instant Client Basic and SQL*Plus software and connect to the database specified in the tnsnames.ora file.
10. Here is the sample output of a successful execution of the setup1 script:
[macosx]/oracle> . setup1
MAC OS X INSTANT CLIENT 10g SCRIPT - SETUP1
TNSNAMES.ORA FILE
# If you receive an
# ORA-12154: TNS:could not resolve the connect identifier specified

Sorry, for my english

you are actually using JDBC so the DSN entry does not matter.
2 things.
Make sure that your oracle database driver is in your classpath on your tomcat server.
I.E. copy the file classes12.jar into your common/lib folder of tomcat, or into your WEB-INF/lib folder of your application. and RESTART your server. classes12.jar can be found on the internet or more easily somewhere within your oracle installation. just search for it.
Make sure your jdbc url is correct. I believe it goes like this.... fill in the blacks
connection conn = DriverManager.getConnection("jdbc:oracle:thin:scott/tiger@MyOracleHost:1521:MyDB");Note how the username are passed in the first string there fore there is no need to pass additional parameters. This method may be depriciated, but if so, just take out the user and pass from the string and continue to pass them as 3 seperate strings.
connection conn = DriverManager.getConnection("jdbc:oracle:thin:MyOracleHost:1521:MyDB","scott","tiger");That should get your connection. if not, post your errors.

Regards,
SumantaIf you have a listener on host BLRD025AL1, and that listener knows about a service named 'sumanta', then you don't need to do anything to your tnsnames.ora to use it with Toad -- or any other client tool. You just have to provide the correct connect string.
What have you actually tried?
What result did you get?
Any oracle errors (ora-nnnnn or tns-nnnnn)?

Unable to connect to Oracle Database using Oracle Sql developer 2.1.1.64

Hi Everyone,
I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:
An error was encountered performing the required operation Got a minus one from read call .Vendor code 0
However i am able to connect using Sql Plus by supplying the username SYSTEM and the corresponding password.
My TNSNAMES .ora file is as follows:

I am new to Oracle and so i need someone in this forum who can help me resolve this problem. Also i even tried connecting to the database using Toad 10.5.0.41. It give me the following error:
ORA 12537 : TNS Connection closed
Thanks for your patience and help in advance.

Connecting to an Oracle database using ASP

Hi
I am having problems connecting to an Oracle database using ASP. I am trying to do this for a school project the school's database server is running Oracle 9i. The repository is version 6. The web server I have access to only has ASP not ASP.net. What kind of connection string would I need to be able to connect to the database?

You do need to ensure that the Oracle client and Oracle server are compatible, but that is generally pretty easy to accomplish. Unless you are trying to cross more than one major release (i.e. 9.2 client to a 7.3.4 database), you're pretty safe there.
You could try downloading and installing the latest 8.1.7.x Oracle ODBC driver from OTN on the machine with the 8.1.7 Oracle client (I believe the last ODBC patchset was 8.1.7.10), but I don't have particular confidence that that will solve the problem. If it doesn't, we can do an ODBC trace to focus in on the issue, but installing a new driver is a much easier process, so that probably ought to be the first step.

Problem about using Oracle Form 6i to connect Oracle Database 10g express.

Sorry to interrupt all of you.
I have encountered a problem about using Oracle Form 6i to connect Oracle Database 10g express.
As I would like to
I use Oracle Net8 Easy Config to create a connection.
According to "tnsnames.ora", the paramater of connection is as follows;
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA = (SID = XE))
Unfortunately, when I use Oracle Net8 Easy Config to test the connection, an error message is prompted as follows:
Connecting....
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
After I google it, I still have no idea how to solve the problem. I would like to ask, could anyone mind providing some hints or solution to address the issues.
Thanks for your assistance in advance.

I don't believe the Net8 Easy Config (NEC) will create a compatible entry in the tnsnames.ora. I have Forms 6i running successfully against a 10g Express database, but I did not use the NEC - I created the entry myself. Here is the entry I use:
XE=
(DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=<<servername or IP address>>)
      (PORT=1521)
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SERVICE_NAME=XE)
)Hope this helps,
Craig B-)
