ins-20802 - oracle net configuration assistant failed during installation - centos 7

Question

Hello I am trying to folow the manual for installing the Oracle 12c. Actually it was already installed on the machine, and then deinstalled.

During installiation I get the "[ins-20802] oracle net configuration assistant failed during installation" error window. And proposed detail log file, where I can see:

Maybe problem is because:

PRCI-1144 : Failed to retrieve Oracle Grid Infrastructure home path
PRKC-1144 : File "/etc/oracle/olr.loc" not found.

Any ideas what I am dooing wrong and how finally install the Oracle?

Answer 1

I found the reason for this exception. If somebody will face the same problem just create /etc/oracle folder and give to it 777 permissions. For me it helped

Answer 2

I also got error "[INS-20802] Oracle Net Configuration Assistant failed" while installing Oracle 12c (12.2.0.1.4) on Centos7.

In my case the error went away after adding an entry in the /etc/hosts file with the hostname and its local network IP.

After that change the installation was able to finish successfully.

Resulting /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
