Complete the instructions in this section only if you have a headless node or if you plan to install on a Mac OS.
Prepare a Headless Linux or Solaris Server
There are two headless server scenarios that require special procedures on Linux and Solaris systems. One is for a system that has no video card; the other is for a system that has a video card, but does not have an X server installed. In some situations -- particularly if your server doesn't have a video card -- you will have to perform both procedures to properly generate reports with the BA Server.
Systems without video cards
The java.awt.headless option enables systems without video output and/or human input hardware to execute operations that require them. To set this application server option when the BA Server starts, you will need to modify the startup scripts for either the BA Server, or your Java application server. You do not need to do this now, but you will near the end of these instruction when you perform the Start BA Server step. For now, add the following item to the list of CATALINA_OPTS parameters: -Djava.awt.headless=true.
The entire line should look something like this:
export CATALINA_OPTS="-Djava.awt.headless=true -Xms4096m -Xmx6144m -XX:MaxPermSize=256m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
If you intend to create a BA Server service control script, you must add this parameter to that script's CATALINA_OPTS line.
If you do not have an X server installed, you must also follow the below instructions.
Systems without X11
To generate charts, the Pentaho Reporting engine requires functionality found in X11. If you are unwilling or unable to install an X server, you can install the xvfb package instead. xvfb provides X11 framebuffer emulation, which performs all graphical operations in memory instead of sending them to the screen.
Use your operating system's package manager to properly install xvfb.
Adjust Amount of Memory Mac OS Allocates for PostgreSQL
If you plan to install the software on a Mac OS, and you choose to use PostgreSQL, you need to increase the amount of memory that the Mac OS allocates for PostgreSQL. You can skip these instructions if you plan to install the software on Windows or Linux.
PostgreSQL is the name of the default database that contains audit, schedule and other data that you create. PostgreSQL starts successfully only if your computer has allocated enough memory. Go to http://www.postgresql.org/docs/devel/static/kernel-resources.html and follow the instructions there on how to adjust the memory settings on your computer.
