PRVE-0044 : No entry in configuration file when checking locked memory limit on node <nodeN>
It seems a minor error, OUI may not require you to fix. But the solution is pretty easy, just add the settings to limits.conf on both nodes.
[root@primary01 ~]# vi /etc/security/limits.conf
...
oracle soft memlock unlimited
oracle hard memlock unlimited

Let’s see the configuration:
[root@primary01 ~]# su - oracle
[oracle@primary01 ~]$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 33315
max locked memory       (kbytes, -l) 134217728
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 16384
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

Now, you can click “Check Again” button on the installation screen again to verify the result.
