Oracle 10g Client and ODAC Side-By-Side

Hi there, I was unable to find an answer to my query by using search, but apologies if this is a double-post.
I'm having some issues with a ASP.NET application running on a Windows XP Pro machine. The machine has Oracle 10g client installed (oraClient10g_home1), and also ODAC (ODACHome2).
The part of my web application that accesses our Oracle DB (10g), always gets a ORA-12154 error when it tries to connect, but SQL*Plus and tnsping for this TNS both work on the machine.
When I use tnsping from the command line it looks like its using parameter files from the ODAC home, rather than the 10g client home.
On my development machine (where ODAC is not installed), the application works fine.
Does anyone have any idea if there are any issues having both of these clients installed?
Or otherwise where my problem could be?
Thanks very much in advance,
James Simm

Thanks for the link, however it hasn't solved my issues:
The version of ODP.Net installed is 10.2.0.2.20, and the Oracle Client is 10.2, so according to that link it should be able to automatically switch between Oracle Homes.
The application I'm troubleshooting doesn't actually use ODP.Net, it uses System.Data.OracleClient, but ODP.Net is required for another application.
I'm extremely stuck, as I cannot understand why I'm getting ORA-12154 when every other Oracle application on the machine can access it.
Please let me know if there are any other things I can try, or if you need any information from me?
Thanks in advance,
James Simm

Error to connect oracle 10g client and designer BO 4.0

hello,
I try to connect oracle 10g client and designer BO 4.0.
I created an ODBC connection to function in the administration tools of data sources but I can not connect once in designer.
I tried using the driver directly oracle designer 10 but I have the same error that is this:
DBD: ORA-12154: TNS: connection identifier specified could not be resolved
someone there had the same concerns?
cordially

Hi,
so it looks like that your TNSNAMES.ORA file isn`t properly configured. Thats why you can connect with the IDT to your Oracle Database.
Your DBA`s should sent you the correct TNSNAMES.ORA file or the entry for your DB prior. After the tnsping works, you will be able to use the IDT properly.

(again) oracle 10g client and oracle 10g express in one computer

hi again, sorry if this question looks like a double post to you.
Well this is quite embarassing yet still make some headache for me. I have my office PC installed with Oracle 10g client using admin component option, for connecting some application with database on remote server. Now, after I have developed some basic map using Oracle 10g Express on my home PC, I want to test it in my office network. But everytime I tried to install Oracle Express, it web interface will working normally while all other aplication can no longer connected with remote server from the client. If I remove Oracle Express, all client connection will working again as if nothing happened. I already created Microsoft LoopBack connection using IP 10.10.10.10, edit TNSNAMES.ORA, etc that could possibly helpful but nothing fixed. Strangely, if I install Oracle 10g Database version, all connection to remote server working again, and map application also working. But this kind of installation takes up all my PC resources (grrrr!). Any more suggestion?
best regards

I'm sorry if the information not accurate, but the client connection made by application which try to connect is simply "not resolved" and show no error code/number at all. I'll try to connect from sqlplus though, maybe the error number will be known from this way.
About 10.10.10.10 tcp loopback, I got this work around from here: http://download.oracle.com/docs/cd/B19306_01/install.102/b14316/reqs.htm#BABGCEAI
in the Ora Database Preinstallation requirement, where it states like this:
+16.In the Properties dialog box, click Use the following IP address and do the following:+
a.IP Address: Enter a non-routable IP for the loopback adapter. Oracle recommends the following non-routable addresses:
+■192.168.x.x (x is any value between 0 and 255)+
+■10.10.10.10+ <---- this is the value suggested that I've been used in my home PC
b.Subnet mask: Enter 255.255.255.0.
c.Record the values you entered, which you will need later in this procedure.
d.Leave all other fields empty.
e.Click OK.
I'll try to remove the loopback later and see the ORA environment, to see the result. In the mean time, all suggestions is highly appreciated.
thank you n best regards

Oracle 10g client and Outlook Address Book

I have looked everywhere that I can think of, and nobody seems to have an answer to this problem. I support an extensive VB6 application, and one piece of functionality, which has been working without problems using Oracle 8i and 9i client, is now having problems when we use it on a client with 10g client installed.
The functionality in question is the ability to click a button that opens the user's Outlook Global Address Book, and return the e-mail address of the address selected. When the application is initially opened, the address book opens without problem. Once the user connects to Oracle (from within the application), from that point on, until the application is closed and restarted, clicking the button to open the address book produces the not-so-helpful error message "This application has failed to start because BJABLR32.dll was not found. Re-installing the application may fix this problem." The .dll is present, and the error only occurs AFTER an Oracle connection has been opened. I'm using an ADODB connection to connect to Oracle.
I have tried closing the connection, and setting the connection object to nothing, but this doesn't seem to make any difference. The Oracle connection appears to be working fine, the recordsets that are returned have the correct data in them, and updates perform correctly as well.
I have a sample application (about 175 lines of code) that I can use to consistantly reproduce the error.
If anyone can shine some light on this, it would be greatly appreciated. If this needs to be posted to a different forum, please let me know that as well. This forum seemed to be the closest match that I could find for this problem.

I am having the same problem, did you find an answer? other than resetting the Path, I shouldn't change all the client machines path

Install Oracle 9i client on a computer with Oracle 10g Client

Hello all!!
I'm using a computer with Oracle 10g client, and I access two databases. One server has Oracle 10g server, and the other server has Oracle 9i server.
I want to install 9i client, to have it also in my computer. I haver read that I just have to install it in a different ORACLE_HOME, but I have a doubt.
If I install 9i client, would I be able to use the utilities, (exp, expddp, sqlldr) of both versions, or which version will be used in the command line for the utilities.
Thanks a lot!!!

To start with, Home Selector is a "9i thing" (and older), in 10g there's the OUI -> Installed Products... -> Environment tab instead.
About the 9i dbca with other Oracle products installed. If you use launch.exe to start via dbca start menu shortcut, it uses ora92\assistants\dbca as working directory ("start from"). So when not looking for "numbered dlls" like oracore9.dll, a later/different version will be loaded if earlier in path, since loading goes through jre directories, ora92\assistants\dbca, then the dir's from path variable. From there it may start to link in libraries from different homes (on my laptop, "launch.exe dbca" uses files from 2 additional home paths!)
But, if you instead use dbca.bat started from ora92\bin, it will look in the right directories first and there's no dll mess-up. (But only when using the correct cwd!)
Plain and simple: stay very far away from multiple-general-home installs. It is possible to install allright, in different homes and all very nicely, but there will be pain when you decide to use the stuff (perhaps with sql*plus as the only exception, but I've run into bugs with that too).

Oracle 10g client connect to oracle 11g server

Hi All,
In my system, i have installed oracle 11g server(11.1.0.6.0). while i try to connect to this server by 10g client in my friends system,which is in the same network,it is showing
ORA-12545: Connect failed because target host or object does not exist,
then i tried with other system (using oracle10g client), its showing
ORA-12154: TNS:could not resolve the connect identifier specified
then i tried with one another system (using oracle 9i client) -- its is connected.
what may be the problem. not connecting using oracle 10g client. and also different error.

user12479258 wrote:
Hi,
The client version is 10.2.0.1
this version may not be connect to oracle 11g?
If so then which are the client version will connect to oracle11g server(11.1.0.6.0).A 10.2 client will connect to an 11.x database, but the sqlnet.ora and tnsnames.ora files must be configured correctly. The errors you reported are not uncommon and have been diagnosed repeatedly on this forum. Let's not confuse the issue by comparing / copying files from various machines, as that has already created a moving target of error messages.
On the client that is exhibiting the problem ...
Do you have a single ORACLE_HOME? A single TNSNAMES.ORA?
On that machine, at a command prompt, do a tnsping on the service in question. Also try to connect with sqlplus. Copy the entire session -- commands and results -- and paste it all back here.
On the server machine, log on as the owner of the oracle software, and at a command prompt enter the command "lsnrctl status". Again, Copy the entire session -- commands and results -- and paste it all back here.

Problem Installing Oracle 8i and Oracle 10g client on same machine

Hi Gurus,,
I am new on DBAside....
I have already installed Oracle 10g R2.m planning to install oracle 8i on same machine..
What steps should i follow in order to avoid conflict..
The OS is Windows XP SP3....
I know that installing oracle 8i first and than installing oracle 10g is more convinient..But my requirements are different..
so have to install oracle 10g first and then Oracle 8i on same machine..
Thanks in anticipation.

Hold on - it DOES matter - you shouldn't update new repository with old oracle installer, so be careful...

Problem to connect between Oracle 10g xe and VB2010 at Vista sp2

Introduction
Hi guys, good day... NEED RESCUE!! SOS!! Hmm.. i have trouble been 1 weeks trying connect between Oracle 10g xe and VB2010 on window vista sp2. Actaully im very new at Oracle 10g xe and VB2010 but i got a project is going to build up system database and i figure out Oracle 10g xe and VB2010 can use free so i just chows these appication to be my project. I been search around internet and there is several things i was found about the connection but i has try and tried still it wont work out.
Things i found and learned
Oracle
1. I have download Oracle 10g XE and installed in my windows vista sp2.
2. I notice the Oracle Developer Tools is needed for VB2010 (To add reference 'Oracle.DataAccess'). So i was downloaded ODT11beta and installed
3. I also edit TNSNAMES to following below:
OraDb =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = shin-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
4. My sqlnet like following below:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
5.I have try tnsping OraDB and its works.
6. I monitoring task manager and OracleServicesXE is running.
7. ora_dba is added in Group.
Problem in SQLPLUS
When i try connect SQLPLUS in cmd i get ERROR: ORA-12560: TNS:protocol adapter error.
i . In cmd i type sqlplus and enter then i been ask for username and password.
ii. After i insert my username and password and enter then i get the error of ORA-12560.
Visual Basic 2010
1. First i created my project, drawing label and button for test connection.
2. Then, i add reference Oracle.DataAccess into my project.
3. I type following script into my vb form:
Imports System.Data
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types
Public Class Logon
Private Sub cmdLogon_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdLogon.Click
Dim oradb As String = "Data Source = OraDb; User Id = system; Password = shin;"
Dim conn As New OracleConnection(oradb)
conn.Open()
Dim cmd As New OracleCommand
cmd.Connection = conn
cmd.CommandText = "select SName from Staff where SName = shin"
cmd.CommandType = CommandType.Text
Dim dr As OracleDataReader = cmd.ExecuteReader()
dr.Read()
lblOra.Text = dr.Item("SName")
conn.Dispose()
End Sub
End Class
Problem in VB2010
When i run my project and press the button i get error message ORA-12514: TNS:could not resolve the connect identifier specified at conn.Open()
Extra Question*
1. Im notice in my netbook xp home sp2, before i install ODT11beta my sqlplus look fine thought cmd but after i installed ODT11beta its same problem with my Vista sp2 now. Get error ORA-12560: TNS:protocol adapter error :( I tried uninstall ODT11beta again and restart its work fine again. Which i really dun understand. Izzit the version ODT11 is not suitable for 10g xe? And i dunno this problem is related with my connection between oracle 10g xe and vb2010 or not. So confuse@@
2. I wish to know more about connect between Oracle and VB, is there still a things i miss?(I mean steps or configuration that should i done)
3. Or i just lower my VB version could make more easy? If yes, what version VB should i use that could work out with oracle 10g xe?
4. Sorry for too bad my english but i really wish somebody could help me. Please try to understand my written or you could ask me mean if dont understand. Im stuck!! Stuck feel not really that good.....

Huhu..
Yo, henry
I thought the OraDb is just a name for entry but im not sure it is a service. I was refer http://www.oracle.com/technology/pub/articles/cook-vs08.html at topic Connection Strings and Objects.
Here is my lsnrctl service

Izzit ok? I notice there is no listed OraDb. but tnsping OraDb seem fine.
Actually there is somethings as a newbie i wondering long time alreadly ><
1. The origin of tnsname.ora is no OraDb or ORCL but i just simple add it by open tnsname.ora with notepad. Im just not sure it is function or not.
Also please check at my TNSNAME.ORA:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = shin-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)

OraDb =
(DESCRIPTION =

(SERVICE_NAME = orcl)
I got the feeling there is so close~~~!!!

Can't uninstall Oracle 10g client

Wow. I'm not sure this experience could have been any more frustrating. Now I can't uninstall oracle 10g client...
Some of the components you selected cannot be deinstalled because they are installed using Installer version 10.2.0.1.0. Please use Installer version 10.2.0.1.0 or higher
WHAT? Where do I find this new installer? I just want to revert back to 9i client so that hopefully my oledb connections to my oracle database will work again.
UPDATE: Okay. I managed to uninstall Oracle 10g client. It didn't solve my problem :(
I still get this error...
ORA-12705: Cannot access NLS data files or invalid environment specified
I just want to pretend like this whole upgrade episode never happened. What a nightmare.

I just had to click on the same setup.exe icon i used to install it. i didn't realize there was an uninstall option in the setup application.
As far as the error is concerned. When I installed 10g it set one of the registry values for 9i to "NA". Once I changed that registry value back to what it was it worked again. I guess Oracle changes the registry value of old installations in order to ensure they are not active anymore. Since I wanted a side-by-side installation of 10g and 9i I didn't want 9i deactivated. Everything is working fine now.

Slow first connection using Oracle 10g xe and Visual Studio 2008

{noformat}
Good day,
I'm slightly unaccustomed to using forums, so bear with me.
My initial connection to the Oracle database takes approximately 30 seconds. It seems to be waiting for a connection before timing out and trying another connection which works, as all subsequent connections work immediately. I'm unsure how other people's responses in forums can help me due to the plethora of configurations, so here's mine. My comprehension of the oracle world is still growing, you'll have to explain the terms you're using for me, Hoping you can help.
I'm using Visual Studio 2008, set to use 32 bit debug mode, on a Windows 7 Pro platform. Also using Oracle 10g Xe, and have installed the 32 bit version of ODAC 11.2 (11.2.0.1) to aid making a connection from Visual Studio to Oracle.
I have a database set up and a user with system admin rights. This is all local for a programming project and will never see the light of day outside of my personal machine.
I am using code to connect, not the GUI. I wish to code this project completely without the aid of the GUI. so my connection string within Visual Studio C# is (pw/id hidden)...
string xe = "Data Source=xe;User Id=xxxxx;Password=xxxxx;";
OracleConnection conn = new OracleConnection(xe);
My c:\devsuitehome\network\admin\sqlnet.ora file is this:
# sqlnet.ora Network Configuration File: C:\DevSuiteHome\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (LDAP, TNSNAMES, EZCONNECT, ONAMES, HOSTNAME)
And my c:\devsuitehome\network\admin\TNSNames.ora file is this:
tnsnames.ora Network Configuration File: C:\DevSuiteHome\network\admin\tnsnames.ora
Generated by Oracle configuration tools.
XE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = xe)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = <machine name)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = PLSExtProc)
Just for good measure, my tnsping xe shows:
"Used paramter files:<br/>
c:\devsuitehome\network\admin\sqlnet.ora<br/><br/>
Used TNSNAMES adapter to resolve the alias<br/>
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)))(CONNECT_DATA = (SERVICE_NAME = xe)))
OK (0 msec)"
So, how can I make that initial connection faster so I don't spend 15 years testing my application due to slow start-ups? :)
Thank you.
Kevin.

I have formatted my hard drive since my first post. I was running window 64 bit with a higher version of the ODAC and that proved to crash my machine with faulty error messages about memory. I have reverted to a previous version of the ODAC tools and everything works very smooth now. Still the connection time is consistently 20 seconds or longer on the first attempt.
Just a little more information.. I am currently taking a college course with 15 other students, as you can tell by the impersonal machine name, where programming using visual studio 2008, and Oracle 10g xe is expected. All of us are using a 64 bit environment and we all have difficulties cutting down the load time of making the first connection to Oracle. Some people are longer making the connection, but none are shorter.
One other note. After the first connection is made, taking 20 or more seconds, and is closed, all subsequent openings of the connection are instantaneous, for all of us.
If there is ANYTHING more I can get for you, please let me know. With my environment stable as it is, I will not need to format or change any information for the foreseeable future.
Here is the information you requested
1 The connection method I am using, I have chosen the manual connection for you, however the delay exists if the connection is made through the GUI as well.
Historically, I am getting slow connection speeds through adding the connection through the GUI or by a manual connection. Here is how I am doing it manually. I have the connection being created in 20 seconds, which is the best I can get.

I fought for weeks about the ODAC version 11.2.0.1 that you see in the previous post, and that would be a whole new thread. Suffice it to say I have a reliable environment to program in with this 10.2.0.1.0 version that I am running now, and the connection time has not changed, it is still minimum 20 seconds load time, sometimes up to 25.

Oracle(tm) Client and Networking Components were not found..

I installed Oracle 9i Client tools on my machine (Win2000 Server), and successfully installed the Oracle ODBC Driver, however, upon using "Oracle in OraHome92" option in my Administrative Tools System DSN I receive the following error upon attempt to connect to the database with my ASP scripts:
"The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and part of Oracle Version 7.3.."
I also receive the following error on my page:
Microsoft OLE DB Provider for ODBC Drivers (0x80004005)
[Microsoft][ODBC Driver Manager] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed
I have tried every trick I know and at this point am out of options. If anyone has a suggestion I'd really appreciate it.
Thanx
Phil

Need to download Oracle 10g client - 64 bit

I have to move many of my applications to a new server, and this one is a win2008, 64-bit system.
So... I need to download the oracle 10g client - but 64-bit version, and SQL Plus.
But I can't find it. I found 2 big files under databases for 11g, but I want the client; I don't want to set up a new database system. I just want to install the client so my software can continue to talk to existing databases.
Thanks,
Jon

If apps are 32-bit their libraries (e.g. Oracle Client libs) are 32-bit also - regardless if host system is 64-bit or not.

However - simplest way of supplying OCI libraries is by Instant Client.
It's just a few files and not even a real "install", just drop the files in PATH or in same folder as app executable file.
http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
(and if you find it's not suitable for your specific apps, then you could always remove and install the traditional Client package)
If you have ODP.Net, Asp.Net or OLE DB apps, then look for the ODAC package with Xcopy Deployment. It builds on Instant Client (and it is included).

TNS-12541: No listner on Windows VISTA (oracle 10g client)

Hi all,
After installing an Oracle 10g Client for Windows Vista, when trying to connect to the database, i got the error No listner (TNS-12541). I checked the database listner but it's running and i can connect there from XP OS client. Does anybody have an idea about that.
tnsping give the same error also but when i ping the server it gives response.
Any body has experioenced the same problem, if yes could you help please it's very urgent.
Thanks regards
raitsarevo

raitsarevo,
First of all: it's not very urgent. Very urgent requests end up in a SR at http://metalink.oracle.com.
Oracle doesn't support all editions of Vista and 10g may not even support Vista at all. Please refer to the download page for 10g at http://otn.oracle.com for further details.
A non-supported edition of Mickeysoft usually results in Oracle Net issues.
