Maximo 7 comes with BIRT automatically installed.  The problem with this is that if you have a high traffic production environment, having all reports run on the same machine can be taxing and cause performance issues.  There are a few options to consider to improve BIRT performance.  You can install BIRT on report only server, just like some of you did with Actuate, or you could run a second database instance for reporting on an another external system.  But before you go out and start buying new servers, read the BIRT performance consideration guide.  Also take a look at the BIRT reporting feature guide.  [IBM Support]
