Checking I/O Completion Port (IOCP) settings

If you are installing Network Manager on AIX and plan to connect to an Oracle database then you must make sure that the IOCP setting is correct.

You must perform the following steps as the root user.
  1. Issue the following command 
    /usr/sbin/lsdev -c iocp -F status
    Proceed as follows:
    • If this command returns the result Available then you do not need to complete any more steps in this task.
    • If the command returns something other than the result Available, for example, Defined, then complete the remaining steps in this task.
  2. Issue the following command: 
    smitty iocp2
  3. Select Change/Show Characteristics of I/O Completion Ports.
  4. Change State to be configured at system restart from Defined to Available.
  5. Reboot the AIX server.
