SOLUTION:
The solution, as described in Doc ID 1949184.1 is actually a very simple one, all you need to do is enable to IOCP (I/O Completion Ports). The steps to do that are:
1.
Log in as root and run the following command:
# smitty iocp
Select Change / Show Characteristics of I/O Completion Ports.
2.
Change configured state at system restart from Defined to Available.
Restart the machine
3.
Run the lsdev command to confirm the IOCP status is set to Available:
$ lsdev | grep iocp
iocp0 Available I/O Completion Ports
4.
Relink Oracle Home. In order to do that, connect with the Oracle software owner user and then:
Set the ORACLE_HOME environment variableExecute $ORACLE_HOME/bin/relink all5.
That\'s it ! Now the \"dbca\" and \"dbua\" runs successfuly
收起感觉java版本的问题，查下12c需要的java版本及oracle用户的环境变量是否正确设置！
