Recently we have been observing bunch above alerts in 12.1.0.2.0 DB below are the hots details.

Linux picid101 3.10.0-693.17.1.el7.x86_64 #1 SMP Sun Jan 14 10:36:03 EST 2018 x86_64 x86_64 x86_64 GNU/Linux

As per Oracle docs, we got the below solution.

# /sbin/sysctl -a | grep randomize
kernel.randomize_va_space = 1

If the parameter is set to any value other than 0 then ASLR is in use.

On Redhat 5 to permanently disable ASLR.

  add/modify this parameter in /etc/sysctl.conf

kernel.randomize_va_space=0

kernel.exec-shield=0

Is the above solution applicable for my current version ( OS )

Howdy, Stranger!
