MS SQLServer Linked Server using Instant Client?

Does anyone have an example of setting up a linked server in SQLServer using instant client ODBC?

Have issue of connecting to a remote oracle server after following several tutorial online from step A-Z. http://www.dbatoolz.com/t/installing-oracle-instantclient-basic-and-instantclient-sqlplus-on-win32.html
I am the DBA that installed the remote oracle too so every information are right.Either you are mistaken or Oracle is in error.
I doubt Oracle mis-reports reality!

These are the errors: ORA-12154 or ORA-12560 TNS: protocol adapter error.ORA-12154 ALWAYS only occurs on SQL Client & no SQL*Net packets ever leave client system
ORA-12154 occurs when client requests a connection to some DB server system using some connection string.
The lookup operation fails because the name provided can NOT be resolved to any remote DB.
The analogous operation would be when you wanted to call somebody, but could not find their name in any phonebook.
The most frequent cause for the ORA-12154 error is when the connection alias can not be found in tnsnames.ora.
The lookup operation of the alias can be impacted by the contents of the sqlnet.ora file; specifically DOMAIN entry.

Problem using instant client with Win 7

Hi,
I have a Powerbuilder application that runs very well with Win XP and Oracle client 8 to 10.
With new computers (Win 7), we try to use instant client... but there are problems with accents ! In fact, all accents are replaced by a "¿" in the database.
It only appears when we are using our programs from a Win 7 machine with instant client.
Do you know if there is something to configure to solve this problem ?
Best regards.

If the characters only appear on certain clients, then they are NOT being "replaced ... in the database". What you are seeing is an issue with presentation, not data.

Linked server using kerberos working fine then after inacitive for 10 minutes start receiving the anonymous logon error

Linked server using kerberos working fine but after leaving the session inactive for 10 minutes is startin to fall down to ntlm and receive the anonymous logon error

we are connecting to SQL mgmt studio app published on citrix, using Windows authentication and Kerberos to forward the credentials to the linked servers and avoid the double hop issue, that part is working fine, we already have the Constrained
delegation, SPNs and Active directory settings for the Service accounts and the authentication is working, we can connect to the linked servers without errors, it's only whe the Session get idle when we faced the issue, the citrix team already have verifyed
any timeout setting and they mentioned there is no 10 minute timout setting anywhere, we also looked at the Kerberos AD Global policy settings to see if maybe the kerberos service ticket was expiring, but the configured values are Maximum lifetime
for service ticket 600 minutes Maximum lifetime for user ticket 10 hours Maximum lifetime for user ticket renewal 7 days, if you have any other suggestion please let me know.

Hi,
This Could be a double hop problem or some thing could have gone wrong with your SPN
This could also be non trusted Service Account under which your SQL Server is running

How to connect sql server using oracle Client

Hi,
I am working in oracle9i and windows os 32 bit.
I need to connect SQL server 2000 from my oracle client..
I heard about heterogeneous connectivity ...
Please expalin me the steps what to add and how to connect the sql server...
Regs....

Are you trying to connect to SQL Server from your Oracle database (i.e. create a database link in Oracle to SQL Server)? Or are you trying to connect to SQL Server using your Oracle client software (i.e. SQL*Plus)?
The former just requires Heterogeneous Services with Generic Connectivity. The latter is functionality that has been depricated and probably no longer works in your environment.

Problem using Instant Client 10g with PHP4.3.10-16 on Debian Sarge

Hello,
My current email is [email protected]
I am trying to use PHP on Debian box using Oracle 10gR2 on a RH 4 server. Everything works fine individually, but I cannot get PHP4 to use InstantClient to connect to the Oracle Server. This is what I've done:
Oracle 10gR2 works fine on the RH 4 server. Listener is running and all required OS security is in place and works (TCP_wrappers, etc.).
Client machine runs Debian 3.1 (Sarge). It works fine and SSH connectivity to RH4 server works.
Instant Client 10gR2 installed on Debian client and works fine. Tested SQL*Plus connection to the RH server. I installed Instant Client from the zip file.
I did have to add libclntsh.so to /etc/ld.so.conf and run ldconfig to get Debian to use it, though.
Apache2.0.54-5 on Debian client works fine. Web pages on it can be opened in browsers from other machines.
Installed PHP4.3.10-16 on Debian client using following:
./configure --with-oci8-instant-client=<dir of my choice>
--enable-sigchild
I first checked ./configure help and the option with-oci8-instant-client was there.
Configure went well. Log showed checking for Instant Client files.
Ran make. Saw numerous Instant Client message as words scrolled.
Ran make install. Successful.
Restarted Apache2 with following env variables:
LD_LIBRARY_PATH=<my Instant Client directory)
TNS_ADMIN=<same directory where I put my sqlnet.ora and tnsnames.ora files).
SQLPATH=<same directory>
I know this is correct because Instant Client SQL*Plus can connect.
Browsers on other machines can view simple php scripts run from the Debian box.
BUT, phpinfo does NOT show an OCI8 section.
phpinfo does show the correct extension directory, though.
Somehow, my PHP4 configure and make is not using the --with-oci8-instant-client option.
I checked $PHP4HOME/ext/oci8/config.m4 file and the verbiage IS in there to use the --with-oci8-instant-client option, either with the default location or the extension_dir location.
I tried using the new ZendCore product, even though it is not certified for Debian. It installed okay but I could not get PHP5 to work. I uninstalled it successfully and redid all of the above.
So, any ideas as to what else I can do here? Other than not use Debian (which is probably the wisest thing to do). And I suppose I could install a thick Oracle client, assuming that Debian would take it. But I prefer the Instant Client.
I tried the PHP ./configure syntax I've seen several places on this forum.
./configure --with-oci8=instantclient,<directory>
This syntax may work on Red Hat machines but it throws a syntax error on Debian and aborts the configure.
Thanks for any help.

Thanks, but that did not work. Configure aborts because it cannot find the required OCI8 libraries. The --with-oci8 option is for the Oracle "thick" client. I have only the Instant Client...and am not interested in loading the older client.
I may have my own solution next week, though. I will be loading RH4 on a new server and will then install ZendCore and forget all about using Oracle with Debian.
Update on trying ZendCore on Debian Sarge:
I tried installing it again yesterday. The install seemed go to well, and said it was successful.
It did NOT load PHP5, however. Nor did it load the Instant Client. My previously installed PHP4 and Instant Client remained in my original directories.

How to use Instant Client 10G DSN-less feature with SQLDriverConnect?

We have been trying to use the DSN-less feature of the latest Instant Client, instantclient10_2, with the ODBC programming interface using SQLDriverConnect.
We are getting ORA-12560 errors and believe that our connect string isn't correct. The docs don't provide an example or indicate the correct keyword(s) to use.
The help file's "Format of the Connection String" page doesn't provide any clues and DBQ is definitely not working.
What format should be used?
Thanks

...So I take it that I'll have to have the server
export to csv or a db format that will provide a
connection on a stock xp or vista box.I'm not sure exactly what you're saying here. Are you suggesting that you'd export the data on the server to a CSV file, copy that to a network share, and have your application create an ODBC connection to the CSV file?
Are you wedded to installing absolutely nothing else? The Oracle Instant Client, for example, just requires copying 3 or 4 DLLs to a directory & setting some environment variables in order to install a minimal Oracle client and ODBC driver (though it won't work with the Microsoft ODBC driver for Oracle). That's normally a pretty minimal burden for an application to include in its installation scripts.

#Deleted in all fields using Instant Client ODBC

Finally I got Instant Client ODBC installed and working. The trick seemed to be defining ORA_HOME, TNS_ADMIN, and the PATH to point to the Instant Client directory - and alphabetizing the entries in tnsnames.ora!
Anyway, now in linking tables within MS-Access there is one particular table that displays "#Deleted" in all columns of all rows. If I link to the same table using the regular Oracle ODBC driver, everything displays as it should.
I don't believe there is anything unusual about the table, no bigints. I show the columns below. Is there an explanation, and more importantly, a fix for this?
ML_TRANSACTION_ID VARCHAR2 16
ML_NAME_FIRST VARCHAR2 50
ML_NAME_LAST VARCHAR2 50
ML_ADDR1 VARCHAR2 64
ML_ADDR2 VARCHAR2 64
ML_CITY VARCHAR2 32
ML_STATE CHAR 2
ML_POSTAL_CODE VARCHAR2 10
ML_COUNTRY VARCHAR2 50
ML_PHONE VARCHAR2 25
ML_EMAIL VARCHAR2 150
ML_TRANSACTION_DATE DATE 7
ML_TRANSACTION_FREQ NUMBER 3,0
ML_TRANSACTION_AMT NUMBER 11,2
ML_TRANSACTION_TYPE CHAR 5
ML_REPEAT_ID VARCHAR2 16
ML_REPEAT_DATE DATE 7
ML_COMMENT VARCHAR2 512
DONATION_ID NUMBER 22,0
IS_PROCESSED CHAR 1
FILEDATE_STRING VARCHAR2 10
IMPORT_DATE DATE 7
BATCHNO VARCHAR2 16

Hi all. Just got ODBC working w/the instant client and would like to add what I've found with this with some quick testing.
I created a new Access 2002 database and created links to a test database on our 8.1.7.4 db. Created a link to the same schema/table in the test 10g database. The table from 8x works fine. The table from 10g has the #deleted for all data. On tables from 10g where the primary key is defined using a numeric column (seq number generated) the data look fine. If the table has a text based PK then I get the #deleted for all rows. The same keys in the 8x tables work fine.
Hope this helps in tracking down what might be amiss.

OCIEnvCreate fails with -1 using Instant Client 10.2.0.1 on Windows XP

I have a working application (using the full Oracle install) and I'm trying to see if I can get it to work using the instant client. I installed the client, changed my path and rebooted. According to the instant client how to install - it should just work but then if everything worked like it was documented then lots of support folks wouldn't have jobs. The only parameter I'm setting is the OCI_THREADED flag. The database is on a different server - but that shouldn't matter I'm not getting that far. I am logged into an administrator account on the client box - so I'm not sure what else could be wrong. Also if anyone knows why we always seam to need administrator accounts that would be a great piece of info too.

It should work if you follow the instructions on the instant client page on OTN:
http://www.oracle.com/technology/tech/oci/instantclient/index.html
Are you able to connect to SQL Plus after setting up instant client ?

Help Using Instant Client ODBC on Linux

I am familiar with using ODBC and visual basic under Windows. I would like to use the Oracle instant client ODBC under Red Hat ES3 within a C or C++ program to access an Oracle database.
Where can I find documentation related to this:
a) setting up an ODBC connection on Linux
b) installing the Oracle instant client on Linux
c) building an application with Oracle instant client ODBC
Am I correct in assuming that any C/C++ ODBC code examples from windows could also be used on Linux.
Thanks,
Werner

We are also interested in the very same thing. We are using third party compiler called SIMSCRIPT from CACI which has a module called SDBC for database connectivity. SDBC requires ODBC to be installed/configured. Our application is for Linux, therefore we are interested in using the ODBC driver on Linux clients to connect Oracle database servers on Linux and Sparc. I see the odbc related zip (for 10g) and rpm (for 11g) instant client files on the OTN Instant Client download page. How to install/configure odbc instant client? Is there a document/whitepaper/Metalink Note ?
Thank you

TNS_ADMIN (path to tnsnames.ora) using Instant Client IGNORED

Hi,
I developed a simple utility which uses OCCI LIB from 10g release. I'm deploying it with Oracle Instant Client lite libraries.
Everything works fine when tnsnames.ora is present in the same dir. When I move it somewhere else and set TNS_ADMIN to that directory, it doesn't work anymore:
C:\uplob>set TNS_ADMIN=c:\tns;
C:\uplob>echo %tns_admin%
c:\tns;
C:\uplob>uplob u/p@xe 15 input.dat
Exception:12154 ORA-12154: TNS:could not resolve the connect identifier specif
ied
This seems very simple, but I still cannot determine why TNS_ADMIN is not being taken into account.
Thank you for any help with this issue,
david

I think for Windows ,
You may have to set this in MY-COMPUTER-->Advanced-Env-Variables
and reboot to take effect.

Unable to connect remote databse via windows XP(using Instant Client)

I have downlaod instant Client and the PATH env variable automatically is set when I install Instant Client. Then I try to connect using the following(from the path C:/XEClient/bin):
sqlplus username/passwd@//host:[port][service name]
I get the following error:
ORA-12170: TNS: Connect timeout occurred
When I ping the host I get reply.
Also I am able to connect to that same database thru perl( so I presume there is no problem with the database not avaiable or port not open etc), where additionally ORACLE_HOME and ORACLE_SID env variable are set to the path in the remote machine. The databse version is Oracle 9.2
Below is the sqlnet.log:

===========================================================
Am I missing some set up.
Can anybody help please...I have been trying since last 3 days.
Thanks

Hi Laurenz,
Sorry to say...but it still does not connect(incorporated your suggestions), nor is the trace generated. sqlnet.log looks no different. As about any other oracle clients...I did not have any until yesterday evening when we installed the entire 10g oracle...client and database.
Anyways now too after having installed oracle 10g on D drive, no succes in connecting to remote databse.
Two questions:
1. Is XE client compatible with 10g database? As I am trying to connect to 9.2 version as mentioned in my initial query.
2. When I ping the host I do get reply. BUT when I telnet i.e.
telnet host port
....it says "could not open connection to the host, on port XXX: connect failed"
Does it mean there is a firewall at the remote end which is preventing the successfull connection? But then how do I connect thru' Perl with no extra info...
Any other suggestion please let me know...and also do you suggest I uninstall all oracle clients other than XE...or is there any way out ...having multiple clients?
Another query...hope I can use toad after having set up the XE client?
Thanks in advance...

Linked server using ASEOLEDB

Hello.
Has anyone managed to get a linked server working between SQL 2008R2 and Sybase ASE 15.7 using the SAP/Sybase OLE DB driver and not using an ODBC DSN?
I've tried what seems like every combination of parameters to create the linked server both through the GUI and using sp_addlinkedserver, all to no avail.
If you could supply an example sp_addlinkedserver call that would be really helpful.
Thanks.

Hi Hedgehog,
According to your description, you need to create a linked server to Sybase by using ASE OLEDB provider, right?
If in this case, you need to install the DataDirect OLEDB Provider for Sybase on the machine running SQL Server. And you need to create and configure a Data Source before creating a linked server. Here is a blog which describes how to create a linked
server in SQL Server Sybase ASEdatabase using OLEDB provider.
