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!
Enabling Direct NFS Client – documentation
Oracle Database Installation Guide for Microsoft Windows – Oracle Database Postinstallation Tasks – 126.96.36.199 Enabling Direct NFS Client: http://docs.oracle.com/database/121/NTDBI/postcfg.htm#CHDFGFDC
ps. on Windows the supported ‘nfs_version’ is still NFSv3 :(
Ah, an old client is trying to connect to Oracle 12c (presumably)… ;)
Also “ORA-03134: Connections to this server version are no longer supported” can occur.
This actually implies that the authentication protocols use between client and server do not match. In Oracle 12c, the authentication protocol uses SHA-2 encryption algorithm by default, where older clients use SHA-1. So when an older client is used with defaults, the server will not accept the connection.
The best option would be upgrading the client, but when older dll’s are used (like ojdbc14.jar and you can not change this), this is a problem. The database instance can be told to accept older clients and use the older SHA-1 encryption algorithm.
Well, I have configured some 30 ‘Data Guards’ by now, but I never came across this warning, it seems it’s new in 12c:

During the installation of Oracle 12c (12.1) I encountered the following error:
Error in invoking target 'irman ioracle' of makefile
See '/u01/app/oraInventory/logs/installActions2015(...).log' for details.
Inside the logfile the following error is encountered:
INFO: collect2: ld terminated with signal 9 [Killed]
According to metalink doc 2040972.1 this is due to less memory available (in a VM environment). Continue reading
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
