Operating Systems AIX What are the ideal ulimit settings for root user in AIX? Post 302902410 by rbatte1 on Tuesday 20th of May 2014 11:46:30 AM

The limits are there to protect you. For a superuser account and indeed any other account, you have to ask yourself how much damage it could do by not having a limit.

I don't think that performance will come into it much unless your processing goes wild and an unlimited (or loosely limited) account starts grabbing all the system resources. This need not be a superuser either. We're had other software holding accounts grind a server to unusable. It's hard trying to escape even if you are already logged on as a superuser. Things like ps start failing and the like.

As a rule, I'd generally allow the least that I actually require.


Just my humble opinion though.

XDG-SETTINGS(1) 						xdg-settings Manual						   XDG-SETTINGS(1)

NAME
xdg-settings - get various settings from the desktop environment SYNOPSIS
xdg-settings {get | check | set} {property} [subproperty] [value] xdg-settings {--help | --list | --manual | --version} DESCRIPTION
xdg-settings gets various settings from the desktop environment. For instance, desktop environments often provide proxy configuration and default web browser settings. Using xdg-settings these parameters can be extracted for use by applications that do not use the desktop environment's libraries (which would use the settings natively). xdg-settings is for use inside a desktop session only. It is not recommended to use xdg-settings as root. OPTIONS
--help Show command synopsis. --list List all properties xdg-settings knows about. --manual Show this manual page. --version Show the xdg-utils version information. PROPERTIES
When using xdg-settings to get, check or set a destkop setting, properties and possibly sub-properties are used to specify the setting to be changed. Some properties (such as default-web-browser) fully describe the setting to be changed. Other properties (such as default-url-scheme-handler) require more information (in this case the actual scheme to set the default handler for) which must be provided in a sub-property. EXIT CODES
An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned: 1 Error in command line syntax. 2 One of the files passed on the command line did not exist. 3 A required tool could not be found. 4 The action failed. EXAMPLES
Get the desktop file name of the current default web browser xdg-settings get default-web-browser Check whether the default web browser is firefox.desktop, which can be false even if "get default-web-browser" says that is the current value (if only some of the underlying settings actually reflect that value) xdg-settings check default-web-browser firefox.desktop Set the default web browser to google-chrome.desktop xdg-settings set default-web-browser google-chrome.desktop Set the default mailto URL scheme handler to be evolution.desktop xdg-settings set default-url-scheme-handler mailto evolution.desktop AUTHOR
