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.
