Abstract

A parallel database is one where the data (i.e., tables, views, etc.) is "spread" over "n" nodes (i.e., physical nodes). Each node that is part of the "parallel database configuration" needs to know which other nodes are part of the configuration. This is accomplished via a "configuration file", with each node having the same copy of this file. A sample is as follows:

Graphical Interface to Save a "Parallel Database Configuration"

      A parallel database is one where the data (i.e., tables, views,
etc.) is "spread" over "n" nodes (i.e., physical nodes).  Each node
that is part of the "parallel database configuration" needs to know
which other nodes are part of the configuration.  This is
accomplished via a "configuration file", with each node having the
same copy of this file.  A sample is as follows:

        0                   node1

        1                   node2

        2                   node3

      This disclosure provides a graphical interface for creating and
distributing such a file to all nodes that comprise the "parallel
database configuration".

      PROCESSING DESCRIPTION - A user would perform the following
scenario to configure nodes for a "parallel database system".

1.  The user enters a command which brings up the initial 'selection
    list' window.

2.  The user places the sprite (i.e., mouse pointer) on the
    "Configure PDB nodes" row and clicks a mouse button.  The
    selected row will appear in reverse video and in below the
    "Selection" title (Fig. 1).

3.  The user places the sprite in "OK" box and clicks on a mouse
    button.  The user is then presented a window with all the
    possible nodes (Fig 2.).

4.  To add a node to the "configuration" the user just needs to move
    the sprite to the box on the left hand side of the node name and
    click a mouse.  When the node is "in the configuration" a scale
    bar appears below the node name (Fig. 3).  Clicking a mouse
    button on again deletes the node from the "configuration" and
    removes the scale bar underneath t...
