Chapter 39. Libaio Native Libraries

HornetQ distributes a native library, used as a bridge between HornetQ and Linux libaio.
Refer to the Installation Guide for instructions on downloading and installing HornetQ on Red Hat Enterprise Linux.
libaio is a library, developed as part of the Linux kernel project. With libaio, writes are submitted to the operating system where they are processed asynchronously. When the writes have been processed, the operating system calls the code back.
This is used in the high performance journal if configured to do so. Refer to Chapter 13, Persistence.
These are the native libraries distributed by HornetQ:
  • libHornetQAIO32.so - x86 32 bits
  • libHornetQAIO64.so - x86 64 bits
When using libaio, HornetQ will always try loading these files as long as they are on the library path. Refer to Section 5.1, “Library Path”.
