Enabling asynchronous I/O on AIX

IBM® Tivoli® Directory Server requires asynchronous I/O be enabled on AIX® systems.

About this task

Asynchronous I/O must be enabled on AIX systems if the system hosts IBM Tivoli Directory Server.

Without asynchronous I/O, DB2® database instances cannot be started successfully.

Without asynchronous I/O, Oracle database instances cannot be started successfully.

To enable asynchronous I/O, follow these steps:

Log in to the system as root.
Open a terminal and run the following command:
```
smit chgaio
```
From the System Management Interface tool (SMIT) dialog box, change STATE to be configured at system restart from defined to available.
Click OK.
Exit SMIT.
Run the following command from the command line:
```
smit aio
```
In the System Management Interface tool (SMIT) dialog box, select Configure Defined Asynchronous I/O, and then click Enter.
Restart the system to enable the changes.
