E.5.1

Video Files and Your System Resources

On Sun systems, the video files are loaded into your AnswerBook2 server’s directory.
Each video file in this AnswerBook2 document can be as large as 60 Mbytes. The size
of the video file is displayed next to its video icon in the AnswerBook2
documentation.

When you click on the video icon, AnswerBook2 downloads the file to your local
system’s

/tmp

or

/swap

directory, and then launches the video player for which

your browser is configured.

On Sun systems, usually the system administrator often configures the

/tmp

or

/

swap

directory to be about twice the capacity of the system memory. On the Sun

system where you will be viewing these videos, make sure that the system
administrator configures the system

/tmp

or

/swap

directory to support playing

video files as large as 60 Mbytes.

When you quit the video player, the

/tmp

or /swap space is released. If you do not

quit the player, then it is possible for your

/tmp

or

/swap

directory to become full.

We recommend that you quit the player after watching each video.

Downloading video files can take a few minutes, depending on the size of the file
and the amount of network traffic. Because load time is so dependent on your
network environment, it is impossible to be more specific. The status bar at the
