DB Connection Problem: Redhat 4.1-Oracle 10.2-Apache 2.0.54-PHP 5.0.4

Hi I have all the above running on a single Redhat server
Apache starts fine
PHP config page shows fine on Apache with OCI module loaded
sqlplus scott/tiger@tnsentry> connects fine
sqlplus scott/tiger@//<ip>/<service> connects fine
... but PHP will just not connect to the db
I've tried
oci_connect("scott","tiger","<service>")
OCILogin("scott","tiger","<service>")
OCILogin("scott","tiger","//<ip>:<port>/<service>")
OCILogin("scott","tiger","(CONNECTION=(....))")
and all I can ever get are ORA-12154 and ORA-12514 errors
eg the following line....
if ($c=OCILogon("scott","tiger", "//<ip>:<port>/<service>")) { echo "Successfully connected to Oracle.\n"; oci_close($c); } else { echo "Oracle Connect Error "; print_r(oci_error()); }
gives me....
Oracle Connect Error Array ( => 12514 [message] => Error while trying to retrieve text for error ORA-12514 [offset] => 0 [sqltext] => )
I've set ORACLE_HOME and ORACLE_SID prior to starting apache
I've tried putenv("ORACLE_HOME=<oracle home path>") in PHP prior to OCILogon
but nothing seems to work and I'm tearing my hair out
One thing to note is that "root" owns apache and "oracle"owns the oracle software so not sure whether this might be a problem and whether it's recommended not to do this?
If anyone can help me with this I would really be grateful - thanks very much in advance!

Hi there MartynC
Just wanted to let you know that I screwed up - as usual, the simplest of errors.... I created a script around apachectl to start apache and prior to the apachectl start line I inserted
ORACLE_HOME=<my oracle home>; export ORACLE_HOME
...only I mistyped <my oracle home> so apache wasn't finding it
I've corrected that, restarted Apache and now PHP, Apache and Oracle are working fine!
Thanks very much for your offer of help (the only consolation I can take is that possibly this will someone reading this will take note and double check the dumb stuff and save themselves a lot of time and heartache)
Also I should note for anyone interested that my Linux installation is actually Centos 4.1 (a Redhat "clone")

Instant Client Connection Problem - Excel 2007 to Oracle 10g

Dear users,
I would some help to connect Excel to Oracle.
I am using Excel 2007 (32-bit) on Windows Vista Enterprise 64-bit. I want to connect to an Oracle 10g database through our local network using ODBC. I need to fetch some data once into an excel sheet.
There are no firewall issues or connection issues between my current machine , as I can connect from my machine, using SQL developer as a local client to the Oracle Database which is on another machine on the network.
I tried to make an ODBC connection but Oracle is not listed as a driver.
I beleive ODBC is the best way to do this, but please correct me if I am wrong.
It is an Oracle 10G database.
I downloaded instantclient-basiclite-windows.x64-11.2.0.2.0.zip a
I also downloaded the extra ODBC components: *Instant Client Package - ODBC: Additional libraries for enabling ODBC applications.
I unzipped both in a folder called C:\instantclient_11_2
The system path included that. I checked after rebooting.
I placed my tnsnames.ora (which I copied from the server) in that folder.
I got ti from the server : D:\Oracle\Ora10gR2DB\network\admin\tnsnames.ora
I ran the exe "odbc_install" and It told me the ODBC was intalled successfully.
When I went the control panel, administrative tools, ODBC
In the user dsn tab
I added a new entry. I chose the Oracle driver (previously it was not in the list)
Used the following values
Data Source name: OracleL
Description 123
TNS Service NAme: I chose fro ma drop down menu our prod environment. (There are two entries with the production name, one in caps and the other in lowercase)
Userid: my username
I tried Test the connection and got this:
Unable to Connect
SQlState=S1000
[Oracle][ODBC][Ora]ORA-12545: Connect failed because target host or object does not exist
Any suggestions please.
Thnaks in advance.
A.
Thanks for all your help, in advance.

You probably should remove current ic packages and get the 32-bit ones instead.
Start over.

Connection problem for d2k with oracle 9i

Hi,
GoodDay, This is Ramesh. I have loaded the D2K as well as the Oracle 9i to my Windows-XP OS.But whenever i am trying to connect the database through D2K it is not being possible.After giving the user name & password it is showing error message like "TNS Error". Can anyone help me out with the process of connection??
Regards,
Ramesh.

You gave only user name and password, no database string? (hint: the tnsnames.ora file in your Dev2K install should point to the database, which happens to be on the same machine)
Which TNS Error? There are hundreds if not thousands of TNS error messages.

Connection problem to Oracle 11.1.0 on Windows Professional XP (SP2)

Hello
I've recently performed default installations for 3 Oracle Databases, into seperate homes on a newly formatted Windows
Professional XP (SP2) standalone laptop. For all databases Oracle 10.2.0 (rover), Oracle XE (xe) and Oracle 11.1.0 (fido) I
installed APEX and they worked perfectly.
I then installed my Wireless O2 Broadband for my internet which uses DHCP
I am unable to connect to my databases with the wireless broadband connected. I then bring down all databases and turn
off/disable the Broadband,then restart all databases.
Using commands
Set ORACLE_SID=ROVER
sqlplus system/rover@rover
Set ORACLE_SID=XE
sqlplus system/xe@xe
Set ORACLE_SID=FIDO
sqlplus system/fido@fido
Connections are successfull apart from the Oracle 11.1.0 (fido) database with error
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
Can anybody identify my connection problem to Oracle 11.1.0 (fido) database by reviewing my listener.ora, tnsnames.ora and
other configuration files below.
Many thanks in advance
Regards
Ade

How to solve Oracle SQL Developer connection problem ?

Folks,
Hello. I am using Oracle Database 11gR1. The Database Control Console https://localhost.localdomain:1158/em works correctly. I can create a Database and a table successfully.
My OS is Linux and connects to internet successfully.
In order to run SQL statements. we need to use Oracle SQL Developer. I connect Oracle SQL Developer in the following way:
Connection Name: DB1 (this is my database name as well)
Username: SYS (this is the user name I used to login to the Console)
Password: SYS (this the password used to login to the Console)
Connection Type: Basic
Host Name: localhost
Port: 1158
SID: DB1 (this is created during installing the Database)
But the error message comes up: "Status: Failure - IO exception Connection Reset."
Can any folk tell me how to solve Oracle SQL Developer connection problem ?

password: enter_your_correct_password given at the time of oracle installation
role: select sysdba if you would connect as sysdba else select normal for users other than sys
hostname: enter your oracle server hostname or ip address eg:- 192.168.11.12
to find the hostname open terminal/command prompt in oracle installed machine
type ---> hostname
type ---->ping hostname
you can find the ipaddress of the server
port number: 1521 (default) ----> i guess , else check the port number in the tnsnames.ora file under your ORACLE_HOME/network/admin folder

try it

IIOP connection problems .: JDeveloper 3.1 and Oracle 8.1.6

This is my 4th day working on this problem. I cannot get an IIOP connection to work.
I have verfied that the listener is running on port 2481, I have been inside of the init.ora, listeners.ora, I have read the error inside of listeners.log, and I have been trying things with the Net8 Assistant also.
Most of the posts on this subject seem older, I am wondering if anyone has had this problem recently with the versions that I am using. There are so many things I have been told to change, I'm wondering if there is a definitive list of steps to fix this problem.
Any help is greatly appreciated.

Oracle Database Connectivity Problem.. Please Help

Hi , i am having a problem in connecting my JSP page to Oracle. I dont know how to work from Scratch like which classes to download for driver and where to put them so that it works for me please also help me in writng connection String. i am writing this code but it generates an error.
<%
try
Connection conn=null; // defining variable
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@serverName:1521:myDatabase", "scott", "tiger");
Statement st = conn.createStatement();
String sql = "SELECT * FROM POS";
ResultSet rs = st.executeQuery(sql);
String name = rs.getString("DNAME");
out.println(name);
catch(Exception e)
out.println(e);

and the Error is
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver
I shall be thankful to you for your help.

Adeel

Thanks for your reply and sugession. We cannot stop
using JSP actually. I meant while learning JDBC and attempting to debug it.
I have been working with ODBC
drivers and haven't got any problem. Now here you are
talking about Class.... We haven't download the
driver yet thats what i was trying to ask that from
where to dowload those drivers/classes and where to
put them or how to config them . Your Help is always
appriciated because it can be really crucial for some
one else. Any way Thanks again hope to see a reply
from you.That isn't what your OP suggested. It suggested specifically that you didn't know what a class not found exception meant.
You can down load the drivers from oracle. Or you can get them from the Oracle client install - just drill down under the install directory.
As for where you put them, it would be the same place that you put the other drivers that you already have experience with.

JDBC Connection problem in Oracle 11g

Hello Everyone,
Recently we have upgraded our Oracle server from 9.2 to 11g. Since then our Java program scheduled in a shell script (on the Sun Unix server) is not working
and is giving below error
"java.sql.SQLException: ORA-12154: TNS:could not resolve the connect identifier specified"
What is strange is that our Web application which is on the same server (application server is iPlanets) is able to connect successfully. Also I ran the same program on
my local machine and it is able to connect to the 11g database. It is only on unix server (where the app server resides) that is giving problem. FYI the unix server
does not have Oracle client installed so we are using the below in db.properties file (used by application for connection details).
URL=jdbc:oracle:thin:@59.90.26.156:1521:LDPR
The Web application and the stand alone java program (giving problem) call the same program to db connection and also share the same environment (class folder/library files etc).
Also the program was working perfectly fine with Oracle 9.2. Please suggest the solution as I have tried everything that came to my mind.
Regards,
Sid.

Hi ...
Yeah BPEL connect from the back end rather than using weblogic, but to change it ... we need to change the code from BPEL side to connect from the weblogic JDBC services.

Client side connection problems with Oracle

Hello,
I'm using JUnit to test my code and am having client connection problems.
Weblogic server 6.1sp2, oracle 8.1.7, win 2000
I create an oracle user on the fly (with a dynamic name) and then need to connect
so I'm getting a direct connection, rather than using a connection pool.
it works fine when run through the container, but when run through JUnit I get the
following error:
java.sql.SQLException: The pool driver only works within the WebLogic server, it
cannot be called directly in a client. Use the t3 driver.
So i changed the code to:
driver = (Driver)Class.
forName("weblogic.jdbc.t3.Driver").newInstance();
from:
driver = (Driver)Class.
forName("weblogic.jdbc.oci.Driver").newInstance();
and now i get this error:
java.sql.SQLException: No suitable driver
Any ideas??
Thanks!
Sara

Hi Sara,
You may want to look at Cactus framework. This is a JUnit extension
for serverside tests. You won't need to care about server/client
configuration:

Here's the code in the config.xml:

And if I change the above DriverName to weblogic.jdbc.pool.Driver the poolno longer
works, and the direct connection (attempted with weblogic.jdbc.oci.Driver)does not
work either.
Thanks for your help!

I am trying connect to Oracle 8 database through JSP and the webserver is Tomcat5.5. The classes.jar file is in the Tomcat5.5\common\lib directory and the path has also been set to mentioned directory. But I am getting exceptions. The code and the error are given below.
Need help at the earliest.
Thanks in advance.
CODE
Class.forName ("oracle.jdbc.driver.OracleDriver");
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@insrs013:1521:GCR","BILLING_USER", "BILLING_USER");
PreparedStatement pstmt = null;
ResultSet rs = null;
pstmt = con.prepareStatement("INSERT INTO PROJECTIP(PROJECTID, PROJECTSERVERNAME, SERVERIP) VALUES(?,?,?)");
ERROR

hi,
FIrst make one thing clear. By classes.jar you mean either classes111.jar or classes12.jar.Right?If not,please check tht.
Also,u needn't set any classpaths for Tomcat.

Connection problem with LDAP

Hi,
Is it possble to connect 10g version of database using LADAP from forms 6i ?
Thanks
Bcj

Hi Wilfred,
I would like to describe the tests and results which i have tried regarding the connection problem between forms 6i and Oracle 10.2 through OID(LDAP),
Test 1.
Installed forms 6i + patch 17 and Oracle 10.1.0.2 separately, and assigned the forms home to oracle 10 .1.0.2
Received ,the message as, ORA -12154: TNS: could not resolve service name
Test 2.
Installed forms 6i + patch 17 and tried to install Oracle 10.1.0.2 in to the forms home then received an error message as "Oracle 10g database cannot be installed into an existing 7.x or 8.0.x ORACLE_HOME "
Test 3.
Installed Oracle 10.1.0.2 and installed forms 6i + patch 17 in to the Oracle 10.1.0.2 home, here I was able to connect through tnsnames.ora, but not through LDAP.
When tried through LDAP , received the error message as , ORA -12154: TNS: could not resolve service name
Here, forms created NET80 folder and it was trying to connect the database from this folder.
Test 4
Forms installed in test 1 and test 2 were able to connect through the oracle home which created at the time of test 3.
Test 5
Also tried to install the Oracle 10.1.0.2 into the oracle home which created at the time of third test, here again I received the error message as same as the second test.
So, i agreed that it cannot, when this form version is tightly integrated to its oracle net libraries.
After test 3, i have checked the oracle home in the registry all the variables pointing to the 10g database, here i was thinking is it possible to configure the oracle net libraries or any other to get connected.
Thanks for your help

STRUTS - JDBC connection problem

im using tomcat 5.5.9, jdk 1.5, oracle database...
� have a project in struts...
my project works with my compiler with no problem...
*i setup tomcat on C:\jakarta-tomcat-5.5.9
and � made these setting for tomcat:
� added these strings to my CLASSPATH
--C:\jakarta-tomcat-5.5.9\common\lib\servlet-api.jar
--C:\jakarta-tomcat-5.5.9\common\lib\jsp-api.jar
after � deployed my project under tomcat there was a "classes12.zip" file under this path:
C:\jakarta-tomcat-5.5.9\webapps\BILGISU\WEB-INF\lib
� changed it to class.jar
also � have other .jars under the same path above.
these jars are:
classes12.jar
commons-beanutils.jar
commons-collections.jar
commons-dbcp.jar
commons-digester.jar
commons-fileupload.jar
commons-lang.jar
commons-logging.jar
commons-pool.jar
commons-validator.jar
jakarta-oro.jar
jdbc2_0-stdext.jar
struts.jar
struts-legacy.jar
THE PROBLEM IS:
my index page is a "login" page..
i can open the login page under tomcat.
but when � enter the username and password, page says it is wrong username or password although these are true parameters...
i think i still have a connection problem but � dont know how to solve...
MY SEARCHES SAYS:
you have to reconfigure "C:\jakarta-tomcat-5.5.9\conf\server.xml" like that:
<Resource name="jdbc/myoracle"
auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:[email protected]:1521:mysid"
username="scott"
password="tiger"
maxActive="20"
maxIdle="10"
maxWait="-1"/>
Resource name="jdbc/myoracle" ->HERE WHAT IS "myoracle"??? DOES IT BELONG TO MY PROJECT?
you have to reconfigure "C:\jakarta-tomcat-5.5.9\conf\web.xml" like that:
<resource-ref>
<description>Oracle Datasource example</description>
<res-ref-name>jdbc/myoracle</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
will i write this to my web.xml
and what is "auth=Container" here???????
thanks in advance

ONE MORE QUESTION
Im defining the datasource in my "struts-config.xml"
do i have to define them again in "tomcat/conf/server.xml" ...

Connect to different Databases like Oracle, SqlServer,Access,Db2

Hi all,
i'm in the process of developing an application using jsp , which should be capable of connecting to all datbases like Oracle, SQL Server,Access DB2, Sybase etc,
How can i establish that?
Also what all are things i need to take care,which are specific to each of these databases,like datatype differences etc?
Any information or links with sample codes is helpfull.
regards.
Isaac

Theoretically if you use just the JDBC API then you should be able to access all these databases. This will be true if you're not using 'exotic' datatypes or functionality. If you are, then you may be in for problems - for example I've had problems with clobs and Oracle that required Oracle specific code, which goes against what you're doing. If that happens, just have call outs to helper classes that use the vendor specific stuff, and only load these classes if you detect that particular JDBC driver, and abstract these vendor specific classes to a standard interface.
