Cause

I/O Completion Ports (IOCP) module is not enabled on the server.
 
For 12c as a prerequisite one need enable IOCP https://docs.oracle.com/database/121/AXDBI/pre_install.htm#AXDBI8086
 

Solution

To check if the IOCP module is enabled, run the lsdev command:

$ lsdev | grep iocp

The following sample output shows the IOCP status is set to Defined and hence not enabled:

iocp0 Defined I/O Completion Ports

By default, IOCP is set to Defined. To enable IOCP, set IOCP to Available using the following procedure:

  Log in as root and run the following command:

  # smitty iocp

  Select Change / Show Characteristics of I/O Completion Ports.

  Change configured state at system restart from Defined to Available.

  Run the lsdev command to confirm the IOCP status is set to Available:

  $ lsdev | grep iocp
  iocp0 Available I/O Completion Ports

 

Perform a system restart to make the changes permanent.
