would be better to think of DLPAR as an operation to dynamically alter a virtual machine aka LPAR.

WPAR can be seen as the AIX implementation of the jail concept. Solaris has a similar construct known as containers. WPAR differentiate from others in that there are two types - system and application WPAR's.
An application WPAR isolates the application encapsulating the application in a protected environment that can be moved between AIX systems running at the same level.
A system WPAR appears as if it is a regular system. if you know where to look you can see the difference. System WPAR are also mobile capable.

Hope this helps.

Tk_SetAppName(3)					       Tk Library Procedures						  Tk_SetAppName(3)

__________________________________________________________________________________________________________________________________________________

NAME
Tk_SetAppName - Set the name of an application for 'send' commands SYNOPSIS
#include <tk.h> const char * Tk_SetAppName(tkwin, name) ARGUMENTS
Tk_Window tkwin (in) Token for window in application. Used only to select a particular application. const char *name (in) Name under which to register the application. _________________________________________________________________ DESCRIPTION
Tk_SetAppName associates a name with a given application and records that association on the display containing with the application's main window. After this procedure has been invoked, other applications on the display will be able to use the send command to invoke operations in the application. If name is already in use by some other application on the display, then a new name will be generated by appending " #2" to name; if this name is also in use, the number will be incremented until an unused name is found. The return value from the proce- dure is a pointer to the name actually used. If the application already has a name when Tk_SetAppName is called, then the new name replaces the old name. Tk_SetAppName also adds a send command to the application's interpreter, which can be used to send commands from this application to others on any of the displays where the application has windows. The application's name registration persists until the interpreter is deleted or the send command is deleted from interp, at which point the name is automatically unregistered and the application becomes inaccessible via send. The application can be made accessible again by calling Tk_SetAppName. Tk_SetAppName is called automatically by Tk_Init, so applications do not normally need to call it explicitly. The command tk appname provides Tcl-level access to the functionality of Tk_SetAppName. KEYWORDS
application, name, register, send command Tk 4.0 Tk_SetAppName(3)
