Use configuration parameters to set the $DISPLAY environment
variable for thumbnail generation on Unix platforms other than Linux x86 64-bit.
About this task
On Unix platforms other than Linux x86 64-bit, you must configure the X Windows System display by
setting the X Windows System server 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
Locate FileNet.properties in the startup directory of the application server. For example, for IBM®
WebSphere® Application Server
running in the Windows environment, the startup directory is C:\Program Files (x86)\IBM\WebSphere\AppServer\profiles\AppSrv01. Tip: You can find the startup directory for your application server on the Content Platform Engine Startup Context (Ping Page). See the value associated with the Working Directory key on the Ping Page.
