Astah Share Notes

Astah Share System Requirements

Please see the System Requirements. Hardware requirements vary according to number of Astah files, diagram sizes, number or users and max number of concurrent requests.

What you should know before you start Astah Share

  • Performance of Astah Share changes depending on the size of Astah files, machine specifications of both Clients and Servers and the max number of concurrent accesses.
  • Size of Astah file to upload must be less than 10 MB. You are not able to upload any Astah files that are more than 10 MB. Please divide the Astah file into several files and then upload if you want to upload a Astah file that is more than 10 MB.
  • When you upload Astah files, memories are used for the drawing processes of diagrams in proportion to the size of length and breadth of diagrams.
  • Astah Share uploads only one Astah file at one time. If you try to upload more than one Astah file at the same time, the former one will be in the queue for registration so other Astah files will be on a wait until the first Astah file process completes.
  • We recommend you to take a backup regularly to avoid data loss.

Tips in order to use Astah Share smoothly

  • Adjust the JVM option of Tomcat to your environment
    JVM option is configured in the ASTAH_SHARE/startup.sh.
    Default configuration : CATALINA_OPTS="-Xms64M -Xmx512M -Xss2M"
    (Initial memory pool:64MB, Maximum memory pool:512MB, Thread stack size:2MB)
  • When you upload Astah files, do not upload them all once. After you upload one Astah file, please wait for a bit before you upload another one. Because the most of server resources have been used to complete the first Astah file's process.
