Answer 1

Cause

The security limits requirements were not set according the recommended values

The message [client(15674)]CRS-10001:CRS-6021: No msg for has:crs-6021 [n][65536] makes think about the value recommended for oracle hard nofile 65536 in /etc/security/limits.conf

Then these messages makes think that probably the other parameters in /etc/security/limits.conf were not set [client(15669)]CRS-10001:CRS-6021: No msg for has:crs-6021 [l][unlimited] [client(15672)]CRS-10001:CRS-6021: No msg for has:crs-6021 [c][unlimited]

Solution

Using root user make sure that /etc/security/limits.conf are set as follows oracle soft nproc 2047 oracle hard nproc 16384 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft stack 10240

Answer 2

I was installing unsupported version, correct version for Linux 7.1 is 11.2.0.4
