[INS-20802] Oracle Net Configuration Assistant failed.

by ·0 Comments

Product:

Cognos Controller 10.3

Microsoft Windows 2008 R2 server

Oracle 12c database drivers install issue

Symptom:

Cognos Controller demands that you install both 64 and 32 bit oracle client on the controller application server. When you install the Oracle 32 bit client you get an error.

Error message:

[INS-20802] Oracle Net Configuration Assistant failed.

Cause:

The full 32-bit oracle client installation needs to have Microsoft Visual C++ 2010 32 bit installed.

 

Oracle client is downloaded from here:

Oracle Database Client (12.1.0.2.0) for Microsoft Windows (x64)
  winx64_12102_client.zip (64-bit) (925,039,944 bytes)
 

Oracle Database Client (12.1.0.2.0) for Microsoft Windows (32-bit)
  winnt_12102_client32.zip (32-bit) (902,922,170 bytes)

 

Solution:

Download and install MVCPP 2010 from Microsoft
