I received a patch from Baptiste M. that allows MySQLTuner to determine the architecture and total physical memory on a server running AIX 5L. I’ve rolled the patch into github, and you can download the updated minor release there.
The v1.1.1 release also contains a patch from Isart Montane which allows MySQL to check for users without passwords and for slaves that don’t have read_only enabled. This patch has been tested briefly and appears to work well. I didn’t make any recommendations based on the check since many DBA’s may not be interested in using this setting on a slave that is well secured.
