Rampant TechPress is proud to offer the STATSPACK Viewer product for Oracle.  The STATSPACK viewer has been renamed Ion for Oracle, and is now available (at a far lower price then the Oracle STATSPACK viewer) at this site:

Also, beware of foreign unauthorized sites selling the STATSPACK viewer as Ion for Oracle, Rampant TechPress is the only authorized seller for the former STATSPACK viewer software.
