Yes, enabling the Oracle 12c direct NFS client on Windows and it is documented, but I didn’t get changed on Oracle Support (I have send an improvement request for Doc ID 1468114.1)…
One needs to run ‘%ORACLE_HOME%\bin\enable_dnfs.bat’ now, which does NOT copy the ‘oranfsodm12.dll’ over the ‘oraodm12.dll’, but it copies the ‘oranfsodm12.dll’ to the ‘%ORACLE_HOME%\rdbms\lib\odm\’ directory!
After the file has been copied and Oracle is restarted, the [Oracle instance running with ODM: Oracle Direct NFS ODM Library Version 3.0] line in the alert.log is shown!

ps. on Windows the supported ‘nfs_version’ is still NFSv3 :(

Quick Reference To Patch Numbers For Database PSU, SPU(CPU) And Bundle Patches [ID 1454618.1]
This document is getting replaced by Note 2118136.2:
Download Reference for Oracle Database/GI PSU, SPU(CPU), Bundle Patches, Patchsets and Base Releases [ID 2118136.2]
Oracle Database, Networking and Grid Agent Patches for Microsoft Platforms [ID 161549.1]
In 10g and 11g Enterprise Edition, one could select which options to install or not to install during the installation process (excl. the 10g ‘custom database’ option, you would get partioning, OLAP and rat). In 12g, one is not able to choose during install anymore, you will get all the options and they must be removed afterwards. Remove / disable them after installing the database software (only), but before creating databases.
The best way to do this is using the ‘chopt’ tool, or when the option is not available, the Oracle Universal Installer must most likely be used. It’s available in Windows and Linux. When using Windows, one can also rename the .dll’s which ‘enable’ the options. It will NOT remove the objects from the database! Continue reading
I have been trying to run VBoxManage.exe from the Windows Task Scheduler to periodically list vms. The problem I had was that it wouldn’t list the VM’s I had registered, even if the task was run as the user that created the VM’s and with the ‘Run with highest privileges’ selected.
When searching the Internet, I saw more people having difficulties running it this way, so I started experimenting. Using ‘psexec‘ and ‘runas’ (use the /savecred option and run it once manually from command line) did work when running the VBoxManage.exe as the VM’s creator user while being logged as someone else, but running it from the Task Scheduler still did not work.

I recently updated to Internet Explorer 10 (Windows 7 64bit) and when I browsed to a website with a security certificate problem: “There is a problem with this website’s security certificate.”, the “Continue to this website (not recommended).” option was missing!!!
The issue here is that Microsoft restricted access to pages which are using a key using less than 1024 bits for protection. Some Oracle product using websites (including Oracle VM Manager) are still using this!
I had this problem, when trying to connect with the External Authentication Method, using the Remote Display server in VirtualBox (4.1.8 and 4.2.0). When I want to connect with Microsoft’s Remote Desktop (mstsc.exe), it failed every time with “Your Remote Desktop session has ended. Your network administrator might have ended the connection (…)”.
Sometimes… as Oracle DBA you need to connect to SQL Server (with Oracle SQL Developer and jTDS plug-in installed).
When using ‘SQL Server Management Studio’, the ‘Server name’ is in the format:
This won’t work in SQL Developer:
Status : Failure -Unknown server host name 'SERVERNAME\INSTANCE'.
This can be solved using the ‘hostname’ in the next format in SQL Developer:
For me it worked :)

The Oracle Database version compatibility matrix and version support status matrix are almost mandatory when installing or upgrading clients or servers.
For information about patches, go here: Oracle database patches for Linux and Windows (on Metalink).
For announcements of security fixes, go to Critical Patch Updates, Security Alerts and Third Party Bulletin.
Oracle Database client / server version compatibility matrix
Oracle calls this Client / Server Interoperability Support, Note ID 207303.1
Oracle Database version release support status matrix
Oracle calls this the Database Releases Support Status Summary, Note ID 161818.1
You will be redirected to Oracle Support and you must be registered to gain access to the pages. I did not include the matrices, because these change over time.

Installing the Oracle Instant Client will save you ~600 megabyes compared to the ‘full’ Oracle Client.
- Read some basic info here…
- Download Basic Package for Oracle site
- Unzip to directory x (your ORACLE_HOME)
- Set PATH (Windows) or LD_LIBRARY_PATH (*nix) to the Instant Client directory x
- Move TNSNAMES.ora to directory x/network/admin (or set TNS_ADMIN and ORACLE_HOME).
- Extend with SQL*Plus Package from (optional)
- Start your application
Read my full article here: Whiteblog – Installing the Oracle Instant Client. (links in referred blog might not work!)
OLE DB, .NET and ASP.NET drivers are not included in the instant client (first Oracle link might suggest it is). These are included in the ODAC package, download them separately at these locations:
