    ORA-12547 TNS LOST during 12c dbca on grid infrastructure.


      Hi All,


      In my test environment, I have installed the grid infrastructure on VMWARE 9 and REDHAT 6.4. After successful installation of grid infrastructure and database binaries when I try to create database with dbca, it shows me ORA-12547 TNS LOST.


      The installation is 2 node grid infrastucture with ASM on shared disc. Using grid and oracle users for grid and database binaries respectively.


      I have searched forum and METALINK also, I got some below documents.


      1. Doc ID 1069517.1it says to check the permissions on oracle binaries as below. I found it ok.

         -rwsr-s--x 1 oracle asmadmin 184286251 Aug  9 16:25 /home/oracle/app/oracle/product/11.2/db/bin/oracle

      2. Many docs suggested to check libaio-*. rpm. I found that  libaio x86_64 rpms are installed , but libaio i686 rpms were missing. I installed them also.

      But still i am getting the error.


      Please suggest.
