Use configuration parameters to set the $DISPLAY environment
variable for thumbnail generation on Unix platforms.
About this task
On Unix platforms, you must configure the X Windows System display by indicating what
device the X Windows System
server uses as the main display.
Procedure
To set the Thumbnail.OI.XWinDisplay parameter:
- Optional: You can use X Virtual Frame Buffer
to improve thumbnail generation performance. No graphics card is
needed on the server.
- Install and configure the X Virtual Frame Buffer (XVFB)
software. For installation instructions, see The X Virtual Frame Buffer.
- Start XVFB. For example, run the following
command.
#/usr/bin/X11/X -force -vfb :1 &
- Set the Thumbnail.OI.XWinDisplay property
in the FileNet.properties file by using the IP address
of the X Windows System server. If no value is supplied for the Thumbnail.OI.XWinDisplay property
in the FileNet.properties file, then the $DISPLAY environment
variable is used. The $DISPLAY environment variable
can be set in the startup script for your application server. A typical setting is as follows:
Thumbnail.OI.XWinDisplay=198.51.100.11:1.0
You can assign multiple values by using a comma-separated
list:Thumbnail.OI.XWinDisplay=198.51.100.21:1.0,198.51.100.22:1.0
For a local X Windows System
server, you might leave out the value of the IP address or server
name:Thumbnail.OI.XWinDisplay=:1.0
