Oledb and path length - Oracle client and networking components ...

Hello,
I've been suddenly getting the
"Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation."
error when trying to connect to an oracle 9.2 database using the msdaora oledb provider.
"..ora92/bin" is in my PATH environoment variable and the hints about setting read and execute permissions on the ..ora92/bin direction didn't work for me. However, what did do the trick, was reducing the length the PATH environement variable to under 182 characters.
Anybody else seen this that can explain what's gonig on here?
Erik

Hello Kamal,
Thanks for your reply
My system looks like this:
OS: MS Windows XP Professional Service Pack 2
msdaora version: 2.81.1117.0
This problem has only recently surfaced, but has now appeared on at least two other systems as well as my own. Any system changes must have happened on all three systems. I have "automatic updates" setup on my computer and they maybe setup on the other computers - could the be responsible for breaking oledb?
Other things I have tried:
The Oracle Oledb provider is also not working. It gives me the error:
"OraOLEDBpus.dll: the specified module could not be found"
When I reduce the size of the PATH variable it works too.
I am always able to run executables from the ../ora92/bin directory. So the path is only being wrongly interpreted by the Oledb providers.

Hi Guys,
I am wondering about this error as while I am using the same code to connect to the Oracle database server in my Windows program with Win Forms, the connection to the Oracle server is established and working fine.
But when I have tried to use it with Web Forms for my ASP.NET Application, it throws me out with these exceptions :
?ex.Message
"Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation.

What is an Oracle Client and why is it needed

Hi,
I have an application that is using an Oracle database as data source. Application and database is located on two different servers. Now I will move application to a new server and to do this I need to install an Oracle client and install this on the new application server. From my understanding this Oracle client is needed to make it possible for the application server to communicate with the database server. I wonder if someone can tell me more about this Oracle client, functionality, role and why it is needed?
I have been recommended to install the Oracle client 10g version. Where can I download this together with instructions of installation process?
FYI - database used is Oracle 10g EE.

Third-party products (and Oracle's own too) need certain Oracle DLLs in order to connect to the database. This set of files is called the Oracle client. You may also want to learn about tnsnames.ora because you need to edit it in order to use Oracle client to Oracle database.

Oracle client and... Forms&reports client?

Hello, to all; may be you could help me:
I have installed a Oracle 9.2.0.6 database in PC-1, in PC2 I want to install the oracle client and the forms and report client... (I mean, PC2 is the PC where I will copy my Forms 6i client/server application and the idea is to put an direct access icon on the desktop to a .fmx... to be able run my application)
I've already insalled the Oracle client, only runtime version (I think 9.2.0.1, which was included in the oracle database installation cd's) but .. I need one more thing.. because I can't execute forms.. I need ifrun60.exe I think.. Where is it? Is there any forms & reports 6i client or similar? or is necessary to install the developer 6i (I don't think so.. but...)
Thank you very much
Jose.

I was reading lots of post and I've seen this two from 2001 related to Forms 5, I suposse they're applicable to Forms 6i?
Forms Client Runtime : where are you ?
Enviado: 27-sep-2001 15:34 Responder
Which version can I install as a pure client version of Forms 6i on a light desktop ? Is there a Forms client runtime like there was with the versions 5.0 and earlier, which we could use just to run a Form, without using any web server, Forms werver, nor using the extra/inter/intra-net ?
Thanx for your help !!
Eric.
re:Forms Client Runtime : where are you ?
Enviado: 27-sep-2001 17:58 en respuesta a: eheede Responder
Yes there is. Just choose Form/Report Server installation and choose customs. There you can choose Form or report runtime only (under Forms and Reports tree node) and click on install!
Remember to choose customs install so that oracle installer bring you the list of the component.
Do you agree? Could it be just begin the Forms&reports installation and after that.. Chosoe custom.. an choose to install runtimes?
(I'll try tomorrow and I will say the result here) I hope it works!!
Thanks

ZAV, Oracle client and applications

Hi,
I have a old client/server software that need a Oracle 9.2 client.
As a test I have created a new snapshot, installed and configured Oracle client and the actual application on Windows XP, second snapshot, did a few changes and built the project.
First I test this on the same build machine - working fine. Then I test the file on a clean Windows XP machine, working fine, started the same test on a clean Windows 7 machine - working fine.
But when I test on a standard Windows 7 machine (with Oracle 10g client) it does not work.
The big question is how to isolate Oracle 9 client from other Oracle client resides on the host machine, or have I isolated too much (I created a cmd link within the virtual application and when I try tnsping within the virtual machine I get time out error.
Does anyone have any luck on virtualize Oracle 9 client and run it on machines with other Oracle clients on?
Regards,
Bjarte

The goal is that SQL*Net will be inter-operable within two major versions.

SSIS used to integrate SQ Server and Oracle - Is it necessary both 32 and 64 bits Oracle Clients installed?

Hi all,
SQL Server 2012 EE 64 bits (SOURCE)
Oracle 12c 64 bits (DESTINATION)
To make my solution - integrate SQL Server with Oracle - work, i had to install both 32 and 64 bits of the Oracle 12c Client. After that, i had to change the properties of my SSIS package to run on 32 bits only (properties > Debugging >
Run64BitRuntime set to FALSE). Before i made this change, the execution of my package was failing, but after setting Run64BitRuntime to false, the package ran successfully. Why is that?
I am thinking of unistalling the 64 bits ORacle Client from my Windows Server, but i fear that if i uninstall, my package stop working.
Any suggestions/corrections will be most appreciated.
Thanks in advance
OBS1: I am using ODBC as the source and destination tasks.

Hi FabrícioPJ,
The 32-bit and 64-bit versions of a provider have the same ID. Therefore, the SSIS runtime will select the appropriate version of the provider to use. 32-bit SSIS Designer always requires and uses the 32-bit version of a provider at design time. However
when running the package in 64-bit mode that the Run64BitRuntime project property is True, it automatically switches to the 64-bit version of the provider. When it couldn’t find 64-bit version of the provider, the package would be failed. For more details,
please see:
http://dougbert.com/blog/post/64-bit-considerations-for-sql-server-integration-services-final.aspx
So in your scenario, it seems that there is not a 64 bit provider for Oracle in your environment, so the issue occurs. Please make sure you have installed the correct 64-bit version of the Oracle provider.
To download Microsoft Connectors v2.0 for Oracle in SSIS 2012, Please refer to the link below:

How to find version and arch of Oracle client installed

Hi all
I have sles 10 sp2 x86_64 on which oracle client 10.2 is installed. this installation was not done by me!
so i dont know what version/architecture (32/64 bit) mode of the oracle client is installed on the client.
from sqlplus -V i get only the version which is installed and not whether it is 32 or 64 bit. how can i find that out.
sqlplus -V
SQL*Plus: Release 10.2.0.1.0 - Production
with a bit of googling i found only the below link which says 10g client 32-bit cannot be installed on a 64 bit system.
i read this Installing 32-bit RDBMS Client software on x86_64 Linux. [ID 1075717.1]
Installing 32-bit RDBMS Client software on x86_64 Linux.
The only release of 32-bit RDBMS Client software that will properly install on an x86_64 Linux OS system is 11gR2 (aka 11.2.0.x)
    * 9iR2 (aka 9.2.0.x) 32-bit RDBMS Client software will NOT install on any x86_64 Linux OS system.
    * 10gR1 (aka 10.1.0.x) 32-bit RDBMS Client software will NOT install on any x86_64 Linux OS system.
    * 10gR2 (aka 10.2.0.x) 32-bit RDBMS Client software will NOT install on any x86_64 Linux OS system.
    * 11gR1 (aka 11.1.0.x) 32-bit RDBMS Client software will NOT install on any x86_64 Linux OS system.
The answer to "why", is that the 11gR2 Client software is the first version that includes syntax so that a 32-bit object is linked.can someone please throw more light on this?

If you have "64bit" string in V$VERSION it means Oracle 64bit is running.
SQL> select * from v$version;

Oracle Client and SqlPlus on Mac Os X Leopard Configuration Script

Hello,
I have just written 2 bash scripts for the installation and configuration of SqlPlus and the Oracle Client v10.2.
The first script MacSqlPlus.sh install the client set the environment variables, the second TNSconnectMac.sh help to configure the tnsnames.ora. They can be found here
http://www.danilovizzarro.it/script/MacSqlPlus.sh
http://www.danilovizzarro.it/script/TNSconnectMac.sh
In order to have them working it's required to download the oracle client basic lite and SqlPlus in the /var/root directory.
A step-by-step tutorial can be found here http://www.danilovizzarro.it/?p=10
Soon I will try to upload a demonstration video.

Doug,
It is possible that there could be data corruption, because this is not a tested, thus not supported, setup. I hope that helps!

I am having trouble installing and using remote desktop client and admin on the same imac. I need help?

Can you give me a step by step on getting the client and the admin part of remote desktop to work? I am new to this and I need for remote desktop to work to install the Faronics Deepfreeze enterprise console on the new imac in office. The OSx version is 10.8.3 Any help will be greatly appreciated. Also, when I go to install the admin, it says that the remote desktop client is not updated and I cant get mac app store to show any updates. May be doing something wrong.

This is what I usualy do to setup ARDclient on a client computer.
on the client computer
go to menu bar (white bar at top of the screen)
click on the apple menu
chose system preferences
click show all button
click Users & Groups
click the lock to unlock
click + to create a new account
chose new account: type "administrator"
name the user some thing applicable like "ARDuser"
set a secure password
click create account
click show all button
click sharing
set the computer name to some thing descritpive that identifies the computer
check remote login
click on remote login
set allow access for: "only these users"
click the +
chose the ARDuser from the list
click select
check remote management
click on remote management
set allow access to "only these users"
click the +
select the ARDuser from the list
click select
check: observe, control, genereate reports, open & quite applications, delete and replace items, start text chat or send messages, restart & shutdown, copy items
click ok
click the lock to lock system preferences
click show all
quite system preferences
At this point you should be able to connect to the client using Apple Remote Desktop using the ARDuser setup above. Make sure the client and the ARD computer are on the same network the same way. IE both on ethernet or both on wifi. On the same internet conenction, if your were trying to conenct to a client over the internet there is more involved.
on the ard computer:
open apple remote desktop
from the left column select discover
make sure the list is set to bonjour
the client computer should show up on the list, with the name set above
select the client from the list
click control
you will be prompted for the user/pass to log into the computer. that's the ARDuser setup in the steps above.

Task dependencies and scheduling in Oracle projects and project management

Am I correct in the belief that Oracle projects/project management does not have the ability to create, manage and track dependencies between tasks in a project ? And to achieve that micro level of planning I need to use something like Microsoft Project Integration ?

Gordon,
Project integration is the link between Oracle Projects and MS Projects.
If you want to define dependencies between tasks, MS Project is best bet
for you.
