Using Memory Visualizer


This GUI utility helps you visualize memory use and track it through time, by displaying a graphic plot. This tool is deprecated, though, and we recommend you use IBM's Optim™ tool.

On AIX systems, if you don't have an X server and the GUI utilities installed, you will need to set up a client workstation.

In our example, since we did not have any application accessing the database, we started the Control Center to provoke activity on the database. This ensures that the database allocates and uses memory. You won't need to do this on an active database.
