  • It is recommended to use a machine that has multiple CPUs or multi-core processor to run Astah Share, because in some circumstances there may be many concurrent requests for Astah Share.

Notices

  • Other Java environment except Oracle Java is not currently supported.
  • It depends on the numbers of Astah files and access users, diagram sizes and maximum number of multiple concurrent requests, however the system environment for Apache Tomcat, Java (which are included in Astah Share installer) and Astah Professional is basically a recommended system environment for running Astah Share on.
