Unable to connect to Oracle Discover Application: ORB Initialization failure

We are running Discoverer 4.1.37 in a DMZ. Some of our internal users receive a "Unable to connect to Oracle Discoverer Application: ORB Initialization failure ..." error when trying to use Discoverer Plus. Our external users are able to connect using Discoverer Plus. We have SSL and Gatekeeper was configured with the machine's IP address (Exterior address), port 443 (exterior port), and exterior proxy address. Networking changes were made to enable users to use one web address instead of two (one for external and one for internal). Also, if I trying to use the machine's IP address in the web address, Discoverer just says "Loading" in the Discoverer Plus status box. If I use the one web address (originally, the external web address), I can log into Discoverer.

How are you trying to connect the database using JPA?
Has your datasource got bind successfully. You should check all these things first. If your datasource has not got binded then debug for that.

Unable to connect to Oracle Applications database (afscpgcs) after clone

Hi,
I have just moved (clone using rapidclone) two of our 11.5.10.2 install from a solaris SPARC 8 to 10 . After the clone, while discoverer 10g works perfectly well in one environment, it is giving the error below in the another environment.
- Failed to connect to database - Unable to connect to Oracle Applications database (afscpgcs)
Notes:
1. For the 2 environments, nothing as changed apart from the hostnames.
2. The password has not changed on both - from source to targets.
3. This happens when launching discoverer 10g from Apps.... discoverer works well on it own if not launched from apps.
I raised a SR with oracle and the 2 things they said have not worked. they said
1. change signon password case parameter - but I cannot find that in the list of system parameters on our system.
2. The other note says apply patch 6430269 and I can confirm this patch has been on the system for sometime.
Please advise on this if you have come accross this before and you can help here.
Thanks

Thanks for your concern. I have used the notes you listed but no luck. One thing I have to point out here is that I have always cloned from solaris 8 to 8 for years without this problem. Now I am cloning from solaris 8 to 10 and the problems is on just one environment. The other is working well. The problem seems to be related to the apps password but the password has not changed at all. Also, I have tried to change the password to something else and ran autoconfig but no luck. Please help

Unable to connect to Oracle Applications database invalid username/password

Hi,
Ou Requirement is we want to connect to Oracle Applications using discoverer plus and discoverer viewer.
Application Server used : 10.1.2.0.2
Oracle Applications : R12 RUP4
We have installed application server 10g with OID and when we try to connect to oracle applications we are getting
A connection error has occurred.
- Failed to connect to database - Unable to connect to Oracle Applications database: invalid username/password.
Regards
Ketan

Hi,
I think better to check with your sysadmin or DBA on this, I had the same isuse before but Apps 11i with Discoverer, I talked to ERP sysadmin and worked fine.
Since applications userid cannot talk with Discoverer schema (eul10_us) and it should directly talk with APPS user and then APPS user can talk with Discoverer user.
To the best of my knowledge I provided.

Did you manage to solve this issue?
I'm running into the exact same error, but installing 11.1.1.7.0 on Windows 2003
Haven't found anything on MOS yet :(
Kind regards,

Unable to connect to oracle driver

I am unable to connect to oracle driver. My code is as follows --
try {
Class.forName("oracle.jdbc.OracleDriver").newInstance();
} catch (ClassNotFoundException e) {
System.out.println("Can't find class oracle.jdbc.OracleDriver");
System.exit(1);
} catch (Exception e){
e.printStackTrace();
When I run the code, I am getting the 'ClassNotFoundException'. I have JVM 1.4 and have included classes12.zip and ojdbc.jar in the class path.
What am I missing?

or better yet, upgrade to a less ancient driver jar.
The driver classname you supplied is correct for Oracle 9i and later, but the driver jar you use is for Oracle 8. It's also for Java 1.2 (hence the "classes12" name), and seriously lacking in features and performance compared to more modern versions.
Of course if you're stuck with a 10 year old database version you have little recourse but to use it, but no reputable company would use something that old any longer, especially since it's been out of support for ages.

FW: ADF BC4J unable to connect to database on Application Server 10.1.3.1.0

Please see ADF BC4J unable to connect to database on Application Server 10.1.3.1.0

Hello Steve. I'm getting the same error message as Carlos got when he tried to fire up the SRDemo. Following logon the splash screen has this error message:
Error
Failed to checkout SRService application module. Ensure your datasource name is SRDemo [case-sensitive!] and that connection settings are properly defined for a database with the SRDEMO schema installed. See server log for more exception details...
Apparently you guys have figured out a fix for this, but my command of JDeveloper/J2EE jargon is pretty limited at this point in my learning curve. (I've heard about Jndi, but have no idea what it does). Is there a statement I can add to the web.xml file that will fix this? If so, what is that statement, and where does it go in web.xml?
Thanks in advance.

Unable to connect to Oracle using OCI Drivers on Linux

Hi Everyone!
I am facing a peculiar issue while using Instant Client on Linux ( 64Bit ) running on Red Hat 4.1.
I have downloaded the instant client version 10.2.0.3(.zip) .so files from the below URL
http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/linuxx86_64soft.html
UPloaded all the files to a directory under /opt and changed the .bash_profile file, the latest content looks like
ORACLE_HOME=/opt/instantclient_10_2
export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME
export PATH
TNS_ADMIN=/opt/instantclient_10_2

export PATH
CLASSPATH=/opt/instantclient_10_2:/opt/instantclient_10_2/ojdbc.jar
export CLASSPATH
Java.library.path=/opt/instantclient_10_2

As i have downloaded the Sqlplus utility as well, i am able to connect to the Oracle FARM via sqlplus.
On the other hand, i am unable to connect to the same database via the application. It constantly gives me the following exception,

I have used the classes12.jar and ojdbc.jar which came with the download and nothing seems to work. A bit surprising when sqlplus works and not the application. I suspect there could be an issue with the driver class. I have been struggling to figure this out for days now...
Can anyone please share their thoughts if something similar was observed earlier please.
Any quick help will highly be appreciated.

ORACLE_HOME=/opt/instantclient_10_2
export ORACLE_HOMEYou don't set ORACLE_HOME with Instant Client.
PATH=$PATH:$LD_LIBRARY_PATH
export PATHThis is unnecessary.
CLASSPATH=/opt/instantclient_10_2:/opt/instantclient_10_2/ojdbc.jar
export CLASSPATHThis is wrong.
It should be:
CLASSPATH=/opt/instantclient_10_2/ojdbc14.jar:<whatever else you need there>
Java.library.path=/opt/instantclient_10_2
export Java.library.pathThis is useless; java.library.path is not an environment variable.
java.lang.UnsatisfiedLinkError: no ocijdbc10 in java.library.pathThe case is pretty clear. You want to use the OCI driver (your URL starts with "jdbc:oracle:oci:"), so the Java Virtual Machine is looking for libocijdbc10.so in the Java library path but cannot find it.
What is also clear is that the program does not use the CLASSPATH environment variable you set, because then it would never have found the Oracle Driver.
So it seems that your program is ignoring the environment you set (which would explain why it also ignores LD_LIBRARY_PATH which you set correctly).
You must have the environment variables set and exported in the shell that starts the "java" executable.
Also, check that there is no other ojdbc14.jar on this machine (use "find").
To help you debug your problem, let me explain how Sun Java sets Java library path on Linux:
- If you start java with "java -Djava.library.path=/some/dir:/other/dir ...", the Java library path is set to exactly that value.
- If you do not specify -Djava.library.path, the Java library path is taken from the environment variable LD_LIBRARY_PATH.
- Directories listed in /etc/ld.so.conf have no influence on the Java library path (which gave me quite a headache in the beginning).
Do you really need the OCI Driver? If you can do with the Thin Driver (i.e., use an URL that starts with "jdbc:oracle:thin:") you don't need any shared libraries at all.

Laurenz Albe

Unable to connect to Oracle 11g server using instantclient_11_1 in AIX

Hi,
I downloaded instantclient-basic-11.1.0.7.0-aix-ppc64.zip from oracle site and used the same for connection to 11g server for testing my application on AIX 5.3 machine. I am also using easysoft driver for the connection. But I am uhnable to connect to Oracle 11g server from AIX 5.3 using instantclient_11_1 client
libraries. I get the error "Could not load oracle libraries". Error is as below:
WARNING: Setup was unable to contact your ORACLE
WARNING: server by using the connection options
WARNING: you specified.
WARNING: Error connecting to DB: -1
WARNING: HY000: [unixODBC][Easysoft][Oracle]Could not load oracle libraries
But I could connect to the same server from AIX 5.3 machine using instantclient_10_2 libraries and same eaysoft drivers successfully.
Looks like there is issue with connecting with instantclient_11_1 client libraries from AIX 5.3. I also tried with using 11.1.0.6.0. Same issue is observed.
Did anybody else face similar issue?
Thanks and Regards,
Prema S
Edited by: user6404935 on Jan 27, 2010 9:47 PM

I you find nobody who has the same problem, here are some hints:
- Try to connect using "sqlplus" from the instant client. If that fails, there is probably a problem with your setup.
- Look if the Easysoft driver supports Oracle 11.1 as client.
Yours,
Laurenz Albe

Unable to connect to the OracleForms application through a J2EE application

Hi there,
I have deployed a custom J2EE application in Middleware instance of my Oracle 10g AS 10.1.2
The application is sso enabled . Once a user logs in the application he is able to see a jsp in which i display hyperlinks for him to access.
One of these hyperlinks is pointing to the forms application.
the url is http://psc-pc0592:7778/forms/frmservlet?config=abs_deploy[b]
Once i click on the URL the forms applet begins to load but as the applet opens up i get the database logon screen.This should not happen
I am already logged and have been verified by sso.
Also the forms configuration is associated with a datasource.
I am not able to get as to why i get that screen when it shoud directly connect to the forms application.
Any help on this is appreciated.
Thanks & Regards,
Madhur Pant

when you go through your carrier provider, there is an additional step in the SSL tunnel. Not sure how this transcribes, but it is possible that your carrier does not use the same port as the one you want it to use.

Client unable to connect to Oracle 10g on linux

I have installed Oracle 10g on an Intel box running RedHat AS 3.0. The database installation was succesful but I am unable to connect to it from the client on my laptop running Oracle 10g client and Winfdows XP Pro. The server ip is 192.168.1.10 and I can ping it from the client:

What am I doing wrong this time?
Your help would be greatly appreciated

ADF BC4J unable to connect to database on Application Server 10.1.3.1.0

Hi,
We had an ADF BC4J application deployed on application server 10.1.3.
We recently migrated the application server to 10.1.3.1.0 (SOA Suite).
The look up is made via JNDI and as far as I can tell my JNDI tree is empty.
This can be checked by going to OC4J_Instance > Administration > JNDI Browser.
The stack trace follows:
==============================================================

==============================================================
The datasource is properly configured and I can test it, so all i can assume is that the jndi lookup is failing and the default datasource which by the way doesnt exist on this oc4j instance is getting used.
Once again i stress that there is no data on the JNDI browser.
Any lights?
Thx in advance

Hello Steve. I'm getting the same error message as Carlos got when he tried to fire up the SRDemo. Following logon the splash screen has this error message:
Error
Failed to checkout SRService application module. Ensure your datasource name is SRDemo [case-sensitive!] and that connection settings are properly defined for a database with the SRDEMO schema installed. See server log for more exception details...
Apparently you guys have figured out a fix for this, but my command of JDeveloper/J2EE jargon is pretty limited at this point in my learning curve. (I've heard about Jndi, but have no idea what it does). Is there a statement I can add to the web.xml file that will fix this? If so, what is that statement, and where does it go in web.xml?
Thanks in advance.

Unable to connect to oracle database 10.1.0.2.0 from jdeveloper 11.1.2.1.0

Hello,
I am trying to connect to oracle database 10.1.0.2.0 from jdeveloper 11.1.2.1.0 to develop an ADF application.
But it is giving me the error
Test failed: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
connection type:oracle(JDBC)
Role :SYSDBA
Driver:thin
Host:localhost
JDBC port:1521
SID:webaid
I am able to connect to the database using SQL*Plus with the same credentials.
Any help is appreciated!

I take it you solved this problem, since you posted this: installing Oracle 10.1.0.2.0 (32 bit) on windows 2003 server

Unable to connect to Oracle database on RHEL4

Hi,
I have completed installation of Oracle 10g release 2. on RHEL 4.
On logging on to the RHEL 4 machine, I am able to start Oracle database and use sqlplus.
However, I am unable to connect to it from my desktop, which is windows xp. The tnsnames.ora file in the windows desktop has been updated. However its not able to connect to this machine. The RHEL4 machine is configured with DHCP. Could this be the problem? I would not be able to configure it with static IP, is there a way to configure it with DHCP? tnsping does not identify the database instance either. I get the following error.
TNS-12560: TNS:protocol adapter error
Regards,
Rishikesh

rishikesh,
On the RHEL4 machine
1. check the listener:
-check if the service name of your database is registered
-check on which NIC/ip address the listener is listening
2. check if you can login using TCP
-do a tnsping of the connection descriptor you are using
If both tests succeed, go to the client (windows XP machine)
1. check if the RHEL4 machine responds to the ping command
if that works:
2. check if the hostname used in ping is the same as the hostname in the connectstring
3. check if the service name in the connectstring is the same as in the listener
4. check if the port number in the connectstrings is the same as in the listener
