The server runs the following software:
- Handle System 7
- Tomcat 6 with Jersey
- PostgreSQL 8.4
- OpenJDK 6 (Java SE 6 runtime)
- daemontools
- CentOS 6
In addition, a placeholder for the website is provided by publicfile running under tcpserver from ucspi-tcp
The Handle System server process has full access to the handle database.
The EPIC process uses the Handle System server to query and modify the handle data. In addition the EPIC server had read-only access to the handle database for queries that cannot be done through the Handle System API or that are too slow.
Scripts for the profile feature are executed in a separate sandbox process without special permissions. This means that scripts have read-only access to handle data.
