Oracle ODBC driver has been enhanced to prefetch LONG and LONG RAW data to improve. To do this, the maximum size of LONG data ( MaxLargeData) has to be set in registry on Windows (also need to add the registry key MaxLargeData in the DSN), and in odbc.ini file on UNIX platforms manually.

Hopefully this blog would help you in getting the common question which I found is very difficult to search and get answer. I have created a UDL file and opened via both commands prompts.Īs we can see above, we can see provider under 32 bit but not 64 bit. Hopefully you know that there are two cmd.exe on 64-bit machine, one is under C:\Windows\System32 and another is under C:\Windows\SysWOW64. You can do that by creating a UDL file as suggested in the link and opening it via 32-bit command prompt. Now you may ask, how do I get 32-bit version? Well, it’s already available as a part of the operating system. Oracle no longer supports applications that use OCI version 7 calls, and these technologies are deprecated. Microsoft OLEDB Provider for Oracle (msdaora.dll) and Microsoft ODBC driver for Oracle (msorcl32.dll) are built by using Oracle Call Interface (OCI) version 7. If you are using Oracle data sources, you should migrate to the Oracle-supplied provider and driver. Here is a snip from one of Microsoft connect item. Oracle is a provider which is supported by Oracle.Oracle has a 64-bit version that is usable for us. For 64 bit, we need to download and use the Oracle client and the provider from their site for connecting with SQL.It was last updated for Oracle 9, and is no longer being updated. MSDAORA is no longer supported by current versions of Oracle.
This blog has highlights of a lengthy conversation. During my recent conversation about Oracle linked server with one of my client, I learned something new about “Microsoft OLE DB Provider for Oracle”.
