AIX has <i>commands</i> for tuning. The files where the tuning parameters are stored are not meant to be edited by hand.<br />
<br />
The respective commands are:<br />
<br />
<i>ioo</i> - I/O options<br />
<i>lvmo</i> - Logical Volume Manager options<br />
<i>nfso</i> - NFS options<br />
<i>no</i> - Network options<br />
<i>raso</i> - RAS options<br />
<i>schedo</i> - Processor scheduler options<br />
<i>vmo</i> - Virtual Memory Manager options<br />
<br />
Each command has its manpage and would recognize the flags &quot;-h&quot; for command usage, &quot;-L&quot; and/or &quot;-a&quot; for a list of tunable values and &quot;-h <i>parameter</i>&quot; for a detailed description of the named parameter.<br />
<br />
For your information, the files storing the values are in the <i>/etc/tunables</i> directory, namely:<br />
<br />
<i>lastboot</i> - values effective at last reboot<br />
<i>nextboot</i> - non-default values to be set/changed at next reboot<br />

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.
