Cause:


The issue occurs since 11g as we are now using /dev/shm when using native PLSQL compilation.




This requires that /dev/shm is of type tmpfs and is mounted with the following options:
With rw and exec permissions set on it
Without noexec or nosuid set on it


If /dev/shm is mounted with "noexec" such an error occurs.


Solution:


Ensure that the /dev/shm mount area is of type tmpfs and is mounted with the following options:
With rw and exec permissions set on it
Without noexec or nosuid set on it"




# cat /etc/fstab
...
tmpfs /dev/shm tmpfs defaults 0 0
...


Old setting in /etc/fstab 


tmpfs /dev/shm tmpfs defaults,nodev,nosuid,noexec 0 0

New setting which fixed the issue 

tmpfs /dev/shm tmpfs defaults 0 0
