Instant client

On Windows XP, do I need adminstration rights to install the 'instant client' from oracle?
I've tried to install it with a normal user. It says it's installed correctly, but when I go to the 'ODBC Datasource Administrator' and want to add it to my user ODBC-Connections, it's not in the list.
What am I doing wrong?
This is what I've done so far:
Downloaded Instant Client + ODBC addon. Unzipped both contents to a new folder, then executed odbc_install.exe. Then I've added the directory to my users PATH.
Now it should get listed in odbc-sources, but it's not.

Hi,
I updated yesterday's thread: database access
Anyway, you could ask your sysadmin to try to set this up with his administrative account?
But there should be no need for this. The instantclient ODBC driver should now be available when you create a new ODBC data source.
Regards,
Yoann.

Not able to connect VS Web Developer Express through instant client 10

I just spent 10 hours attempting to connect Web Developer Express 2010 to an Oracle 10g database. In the end the solution was beyond simple, but with the existing threads there is a lot of talking around the problem. I’m posting this in case it might help someone else.
Obtain the Oracle instant client software that will work for your database. You will only need the basic package.
http://www.oracle.com/technetwork/database/features/instant-client/index-100365.html
Extract the contents to a temp location on your hard disk
Create a directory for the application – it could be anything, but here is what I used
C:\instantclient
Copy the extracted files into the directory you just created.
Right click on my computer and choose properties
Under advanced and environment variables you will need to add the directory you created above to the system variables PATH. You will need to create a new system variable called TNS_ADMIN and put the same c:\instantclient path in it.
Create the file tnsnames.ora under the c:\instantclient directory and put your customized entry in it. Below is an example.
tnsnams.ora file contents
<Alias for this tnsnames entry> =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = <Your Oracle Server>)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = <Your database instance>)
It’s a good idea to restart your system after this installation.
In web developer express use the .NET Framework Data Provider for OLE DB.
Here is the key piece of information!!
Under server name you need to use the alias from the tnsnames.ora file entry. If you do not do this it will not pick up the SERVICE_NAME parm and will give you some goofy error like:
ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect descriptor
or
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Why do I need instant client if I installed 11g1 and it works

sqldeveloper works
em works
sqlplus works
I have a problem with oci8, php 5.2.6, apache 2.2 ...all are installed and working
All the instructions I've found (and there are many) talk about
(1) Zend installs what I already have
(2) installing apache, oci8, php and instant client form scratch
I am NOT going to reduce a working system to scratch.
BTW my oci programs work and they have in the past worked through a client.

What Oracle Software is installed on the machine: client or server?
I concur that there is no need for Instant Client here, indeed it would be a bad idea.
Anything that works with Instant Client should also work with the regular client.
If you encounter any Oracle-specific error messages, feel free to post them and ask for an opinion (even though this forum is reserved for Instant Client, it might be an obvious problem).

Failed to install php-oci8 with instant Client for linux 64

Hello,
I have a 64-bits Linux box with RHEL4, and PHP version has been upgraded from 4.3.9 to 5.1.6. I try to make the connection to remote oracle server.
I download instantclient-basic-linuxppc-10.2.0.2-20060327.zip , and follow the instruction to
install it.
But when i try to install php-oci8*.rpm, no matter which i use:
php-oci8-5.1.6-1.el5.i386.rpm or php-oci8-4.3.9-2.2.el4.i386.rpm
The installation always failed due to dependencies errors with oracle instant client.
I also tried with some other packages like: php-oci8-4.3.9-3.el4.x86_64.rpm
All my tries gave me dependency errors.
sometime like:
error: Failed dependencies:
libclntsh.so.10.1 is needed by php-oci8-5.1.6-1.el5.i386
oracle-instantclient = 10.2.0.3 is needed by
php-oci8-5.1.6-1.el5.i386And I cannt find the right RPM for oracle instant client for linux 64 bits box, and php-oci8 5.1.6 64 bits.
I have been trying on this problem for more than one week, and so frustrated. I will appreciate if I can be guide on this issue.
Thanks in advance!

Instant Client with Entity Framework (ODAC 11.2.0.2.40 Beta)

Is this at all possible (with the current Beta version of ODAC) using the Instant Client installation?
I have got this working using the ODAC1120240 innstallation. But it would be nice for our customers to not having go through this (not all of them are tech savvy:-).
I would like to avoid spending hours hunting for documentation, forums etc if this is simply not possible at the moment.

Any help greatly appreciated!

Hi Rolf,
It's works when you don't have a oracle.dataaccess.client settings(like to change oracle types).
At the end I had to install ODAC using Beta 2, because i am using mapping settings(oracle.dataaccess.client).
I am looking to test the new version 11.2.0.2.50, it's looks like have a XCopy version.
Let us know if you test the new version.
Thanks,
Jorge

Availability of RPM Linux x86-64 10.2 instant client

good morning,
an increasingly important platform for us is Linux x86-64 (actually RedHat Enterprise Linux 4 x86-64), the instant client is available only in zip packaging. Could you indicate whether and approximatically when it could be made available in .rpm package.
It is very important for our deployment on all of the client machines.
I thank you a lot in advance for your time and answer,
eric
PS: on RHEL3 x86 platform, we use the RPM version of the 10.2 Linux x86 and this is very convenient. We would reproduce the same ease of deployment for RHEL4 x86-64

Instant Client on 64-bit Windows 7: Driver does not appear in System DSN

Instant Client on 64-bit Windows 7: Driver does not appear in System DSN tab when creating a new Data source.
What I did so far:
I downloaded the basic and odbc zips for Window 64-bit.
Unzipped the basic zip.
Unzipped the odbc zip to the same directory.
Added the dir path to the System Environment Variable called Path.
Double-clicked on the odbc_install.exe to run it from Windows Explorer.
Then I tried to add the driver to create a new data source but it does not appear in the list of drivers.
From a cmd window, I navigated to the instant client directory and tried to run odbc_install again.
I got the message: Oracle ODBC Driver with same name already exists.
What am I missing?

hello, I did it like that you say,but the result also is "oracle odbc driver with same name already exists". I don't kown what can I do it ,Thank you!

Unable to install 64-bit Oracle ODBC Instant Client on Windows 2008 R2 machine.

I am trying to upgrade the Oracle ODBC driver from the 32-bit version currently installed (ODBC Instant Client Release 10.1.0.5.0, April 2006) to a newer 64-bit version but have not been successful. I have had success at uninstalling and reinstalling the existing 32-bit version package (release 10.1.0.5.0) however when I've tried to install the 64-bit ODBC Instant Client (Release 12.1, December 2012), I run the odbc_install.exe application inside the package. it appears to run without issue/compliant, but then I do not see the 64-bit Oracle ODBC driver anywhere, either if I go via the traditional Administrator Tools --> ODBC Data Sources or if I go to the c:\windows\syswow64\odbcad32.exe route. Further investigation into the ReadMe file (ODBC_IC_Readme_Win.html) reveals that you need the 3 DLLs oci.dll, oraociei11.dll and orannzsbb11.dll which the package does not come with. Where could I obtain the correct version of these DLLs or else where can I get an installation package which already contains them?
Any help with this is greatly appreciated. Thank you

Windows 7 64 Bit machine with Instant Client and 32Bit application

Hello everybody,
the last days a tried to get a 32Bit application to run on a Windows 7 SP1 64 Bit machine ... unfortunately with no success. The application runs on XP Pro and Vista Pro 32 Bit machines against a 11g RDBMS for years. As a refenence we use SQLTools from sqltools.net. It has nearly the same behaviour like the application, because it is a 32 bit application too.
First thing was to install a 64 bit environement to verify if the connection is allright.
- Downloaded instantclient-basic-windows.x64-11.2.0.2.0.zip an instantclient-sqlplus-windows.x64-11.2.0.2.0.zip
- Unpacked both packages into C:\oracle so that they reside in C:\oracle\instantclient_11_2
- Made a directory C:\oracle\tnsnames with tnsnames.ora in it, because the app uses it
- Set the environement variables TNS_ADMIN to point to C:\oracle\tnsnames and added C:\oracle\instantclient_11_2 in front of the path variable
- Restarted the machine
- Opened a commnd shell and startet sqlplus user/password@sid
Everything was allright, I was able to connect to the database as expected
Second thing was to start SQLTools, but as I feard it quitted with an error message when trying to access oci.dll of the instant client.
So i decided to switch to a 32 bit environement as a third thing.
- Downloaded instantclient-basiclite-nt-11.2.0.2.0.zip and instantclient-sqlplus-nt-11.2.0.2.0.zip
- Deleted the old C:\oracle\instantclient_11_2
- Unpacked both 32 bit packages into C:\oracle so that they reside in C:\oracle\instantclient_11_2
- Didn't change anything in the environement, because nothing changed from the view of the system
- Opened a commnd shell and startet sqlplus user/password@sid
But now I wasn't able to connect and got the following error
ORA-28547: connection to server failed, probable Oracle Net admin error
SQLPlus was able to start now, but when trying to connect to the database I got the same error like when connecting with sqlplus.
Does anybopdy have an idea how to manage to get a 32 bit application to run on a Windows 7 64 Bit machine?
Thanks in advance
My packages:
Windows 7 64 bit SP1
Oracle Instant Client basic lite 11.2.0.2.0
SQLPlus 1.5 22D

Have you tried WOW64 ? I have not used this emulator for sqlplus but it works for other 32 bit applications.

Can I install Oracle XE on a system that has the Instant Client installed?

Hello,
After installing Oracle XE (Oracle Database Express Edition 11g Release 2 for Windows x64) on my Windows 8.1 64-bit system, I can not connect to the "Get started" url (http://127.0.0.1:8080/apex/f?p=4950).
The output of "Start database" shows:
The OracleXETNSListener-service is being started.
The OracleServiceXE-service is being started.
The OracleServiceXE-service has been started.
The OracleXETNSListener service refuses to start. Could the presence of the Instant Client have something to do with this?
The Instant Client is installed in C:\Apps\Oracle, with a tnsnames.ora in C:\Apps\Oracle\network\admin.
Oracle XE is installed in C:\Apps\OracleXE.
There is a system wide environment variable ORACLE_HOME, pointing to C:\Apps\Oracle.
In the registry under HKLM\Oracle there are keys KEY_odac, KEY_ORACLE_HOME, KEY_XE, ODP.NET and OracleMTSRecoveryService.
HKLM\Oracle\KEY_ORACLE_HOME\ORACLE_HOME = C:\Apps\Oracle
HKLM\Oracle\KEY_XE\ORACLE_HOME = C:\Apps\OracleXE\app\oracle\product\11.2.0\server
Thanks,
George

XE was the last installed Oracle product. I installed it on my development laptop, so I can use an Oracle database when not connected to the company network.
The instant client was broken by the XE install. Uninstalling Xe fixes this, even without a reboot.

Is my PHP + Oracle9i + Instant client setup ok ?

Hello
I have to developp a script in PHP for windows, using an Oracle 9i database.
Here's my setup :
Windows 2003 Server R2 (all patches applied)
PHP 5.2.0
Oracle 9i 9.2.0.1.1
Instant client 10g 10.2.0.2-20060508
Oracle9i was installed in C:\oracle\
Oracle Instant client extracted to C:\dev\oracle\instantclient_10_2
Here 's the PATH env variable (only oracle partis shown):
C:\Program Files\Oracle\jre\1.3.1\bin;C:\Program Files\Oracle\jre\1.1.8\bin;C:\dev\php5.2;C:\dev\oracle\instantclient_10_2
I deleted the "C:\oracle\ora92\bin" from PATH env variable in order to
the Instant client to be used instead of. Is this a good solution ? Since now I have no more oracle tools available in command line without specifing full path.
PHP is configured to use php_oci8.dll of course. No problem with that.
I tryied to activate PDO but get an error message :
When I run PHP from command line, same error message :
Warning: PHP Startup: Invalid library (maybe not a PHP library)
'php_pdo_oci8.dll' in Unknown on line 0
Maybe it's a bug in PHP, I m not the first complaining about that as far as I know.
My main question remains : Is my configuration the best way to do ? Is there a way not to loose oracle9/bin from PATH ?
Thanks in advance

What is "Oracle Runtime"?
Did you install Instant Client from the Oracle Client CD or did you download Instant Client from http://www.oracle.com/technology/software/tech/oci/instantclient/index.html ?

Connectionstring to be used in ASP for instant client ??

Hi,
I'm trying to use oracle instant client for one of my projects.
I have installed basic, sqlplus and ODBC for instant client.
I have set all the environment variables. I have the tnsnames.ora and sqlnet.ora
So far I have succeeded in connecting to a DB Server through sqlplus. I also created a DSN successfully using the driver "Oracle in instantclient10_2" which gets installed when I install instant client ODBC. These indicate that mos tof settings are right. It is good so far.
Now I'm trying to use a connection string in ASP which connects to a DB server using this instant client.
I need one DSN connection string and one DSN-less connection string.
So far I have tried the following:-
1)
Driver={Oracle in instantclient10_2};Server=<Service Name>;Uid=<UserID>;Pwd=<Password>;
This resulted in the error:-
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Oracle][ODBC][Ora]ORA-12560: TNS:protocol adapter error
2)
StrCon.Open "Driver={Oracle in instantclient10_2};Dbq=<Server IP address>:<port>/<serviceName>", "UserID", "Password"
This resulted in the error:-
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Oracle][ODBC][Ora]ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Can you please help me out with these?
Thanks in advance
Jai

Hello,
I tried to use either of the 2 connections you gave but I still get an error:
DSN
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
Specified driver could not be loaded due to system error 5 (Oracle in instantclient10_2).
DSN-less Connectionstring:
Specified driver could not be loaded due to system error 5 (Oracle in instantclient10_2).
Thanks in advance,
Do you have an idea as why this happens?

Using SQLDriverConnect with special characters in password fails, same info with ODBC (Oracle instant client) works fine

Hi,
on a windows 2008 machine that has the Oracle instant client 11_1 installed (11.01.00.06) i am calling SQLDriverConnect in the following way:
std::string str = "Driver={Oracle in instantclient11_1};Dbq=//10.10.101.66:1521/orcl;;Uid=myUser;pwd=a;b";
odbcRc = SQLDriverConnect(hdbc, NULL, (SQLTCHAR*)str.c_str(), str.size(), (SQLTCHAR*)szConnStrOut, 1024, &cbConnStrOut, SQL_DRIVER_NOPROMPT)) == SQL_ERROR);
as long as the password contains no special chars (namely semicolon) it works fine. but when I try to use special chars in the password It stops working, with an invalid username/password error.
State: 28000 Native error: 1017 Message: [Oracle][ODBC][Ora]ORA-01017: invalid username/password; logon denied
i tried different variations of adding " (\") over the password, over the entire pwd=a;b or braces { but nothing seems to work.
the thing is that using ODBC works! what I did was:
open ODBC, go to System DSN tab, add "Oracle in instantclient11_1", then fill the following information:
Data source name: Anything
TNS Service Name: //10.10.101.66:1521/orcl
User ID: myUser
then i press test connection, enter the password "a;b"
and it works!
I cannot figure out what's my problem.
Thanks,
Roy.

I've created your test table in my Oracle database using this extra character and I'm able to describe it properly.
SQL> desc test;
Name Null? Type
ATTIVITÀ VARCHAR2(40)
My character set being used is:
SQL> select * from v$nls_parameters;
NLS_CHARACTERSET
WE8ISO8859P15
NLS_NCHAR_CHARACTERSET
AL16UTF16
NLS_LENGTH_SEMANTICS
BYTE
So as long as it doesn't work for you in your native Oracle database I don't think it would work with DG4ODBC. So yes, it would be best to log a service request so that the Oracle database support can check out the NLS issue.
Edited by: kgronau on Sep 28, 2011 9:21 AM
To be complete here the describe of the MySQL table native and using DG4ODBC:
mysql> create table TEST (attività Varchar(40));
Query OK, 0 rows affected (0.00 sec)
mysql> desc TEST;
---------------------------------------------------+
| Field | Type | Null | Key | Default | Extra |
---------------------------------------------------+
| attività | varchar(40) | YES | | NULL | |
---------------------------------------------------+
1 row in set (0.00 sec)
SQL*Plus: Release 11.2.0.2.0 Production on Wed Sep 28 09:20:17 2011
SQL> desc "gateway"."TEST"@MYSQL_DG4ODBC_EMGTW_1122_DB;
Name Null? Type
attività VARCHAR2(80)
So in general it should work.

Oracle Instant Client and OUT Parameter of custom type in Stored Procedures

Hi @ all!
I try to set up a simple client application, that calls a stored procedure via Instant Client from C#.
The stored procedure and assiciated types looks like this:
TYPE MYVALUE AS OBJECT
      Id      INTEGER,
      value     FLOAT
TYPE MYVALUELIST AS TABLE OF MYVALUE;
PROCEDURE ReadValues( ID IN INTEGER,
                                    RESULTSET OUT MYVALUELIST)
                                       IS
...I created an Oracle Command executing this SP and added OracleParameters for ID and (where I got stuck) the RESULTSET.
Is it possible to pass a parameter with a custom type from C# in some way?
I already tried it as a function with SELECT * FROM TABLE(ReadValues(1));
With my parameter RESULTSET as the RETURN type. But since I use DML within the procedure, this does not work inside of a query...
Any suggestions?
Thanks in advance!

Hi Greg!
Sorry, I misunderstood the forum topic then. =(
Anyway, in the example you provided in the link, this is nearly exactly my situation. But there the Oracle.DataAccess.Client is used, where the OracleDBType can be called to initialize an object of type person. I use the instant client libraries called by using System.Data.OracleClient. There is only the OracleType enum, that does not contain an object or something similar.
So I do it right now after trying a bit with a ref cursor parameter and an OracleDataAdapter - the ref cursor is passed back from Oracle as a DataReader, so die DataAdapter is able to use it for a .Fill():
OracleCommand cmd = new OracleCommand();
cmd.Parameters.Add("RESULTSET", OracleType.Cursor).Direction = ParameterDirection.Output;
OracleDataAdapter odr = new OracleDataAdapter(cmd);
DataTable result = new DataTable();
odr.Fill(result);Within my stored procedure I just added the following OUT parameter:
PROCEDURE ReadValues( ID IN INTEGER,
                                    RESULTSET OUT sys_refcursor)
                                       IS
currentlist MYVALUELIST;
... [Adding elements to that list] ...
OPEN resultset for select * from TABLE(currentlist);It works now, but I don't like that solution that much since I'm always afraid that there are lots of opened cursors idyling around. Do I have to close this one explicitly after filling my table by the DataAdapter?

Orai18n-mapping.jar in Instant Client, but not in JDBC Driver

Hello,
i searched about my question, but no answer. :(
I downloaded the complete JDBC Driver packages (*ojdbc5.jar* + ojdbc6.jar + orai18n.jar) for Oracle 11g at:
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_111060.html
I downloaded the Basic + JDBC supplement packages of Instant Client of Oracle 11g at:
http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html
There is a mismatch of files between 2 ways of getting the jdbc drivers. In the Instant Client version via JDBC-Supplement, the orai18n-mapping.jar is present, but not in the JDBC way.
Why is the orai18n-mapping.jar present in one way, and not the other? Is it an error? It's all about 11g version of oracle....
Thanks
Bruno Lavoie
Edited by: brlav35 on Mar 4, 2009 3:57 PM

Well, in my understanding, Instant client and JDBC drivers are completely different products: JDBC driver is a full-featured set of packages required to run JDBC-compatible program, i.e. it's enough to run a program in any supported Oracle environment. On the other hand, Instant client is a lightweight version, which does not include several JARs and some of them are present in different form, but it's enough for most JDBC-programs. See: orai18n.jar is a required package for correct Oracle object's VARCHARs attributes handling. It contains locale files for different languages. In orai18n-mapping.jar, there's no many of them, but I suppose it would be enough for the same task (probably they do not store locales in that JAR version, but rather build them on the fly if needed with help of DB - but I don't know for sure).
