Disabling AIO (Asynchronous Input/Output) native transport in WebSphere Application Server

Troubleshooting


Problem

IBM Support might request you to disable the AIO native transport code. In certain cases, this code can have a fairly large native memory footprint, and if the application server is short on native memory, disabling the AIO native transport can increase the available address space for native memory.
