Charts and images not appearing

Charts and other images do not appear in reports in Cognos Analytics Reports if IBM® Cognos® Analytics is installed on a UNIX operating system that does not have X server software installed.

To resolve this problem, configure IBM Cognos Analytics to run with X server software.

Procedure

  1. Find the bootstrap_*.xml file located in the install_location\bin directory or in the install_location\bin64 directory.

    The exact bootstrap_*.xml filename depends on the version of UNIX that you are using.

  2. Add the line <param>-Djava.awt.headless=true</param> to the following startup parameter in the bootstrap_*.xml file: 
    <process name="catalina"> 
       <start>
           <spawn sync="1" wait_time="5">
               <path>${java_home}/bin/java</path>
               <param>-d64</param>
               <param>-Djava.awt.headless=true</param>
               <param condName="${ip_protocol}"
condValue="IPv6">-Djava.net.preferIPv6Addresses=true</param>
               <param>-Xmx${dispatcherMaxMemory}m</param>
<param>-XX:MaxNewSize=${dispatcherMaxMemoryBy2}m</param>
  3. Save the modified file, and then restart the IBM Cognos Analytics server from the IBM Cognos Configuration tool.
