Tutorial ======== Once Orthanc is installed, you can test your installation with: $ xdg-open http://localhost:8042/app/explorer.html Then click on the "Upload" button, drag/drop a DICOM file, click on the "Start the upload" button, and you should be going. For more info, check out the Orthanc Book, starting with the "Quickstart" section: https://orthanc.uclouvain.be/book/index.html Optimizing boot time ==================== If the postgresql package is installed on the local host, the Orthanc service will start after PostgreSQL service. This is because Orthanc can be configured to use PostgreSQL as its database back-end instead of the default SQLite back-end (cf. the "orthanc-postgresql" package). This dependency of Orthanc against PostgreSQL can slightly impair the boot time if Orthanc is configured to use SQLite or an external PostgreSQL server. If you wish to optimize your boot time, you can safely remove "postgresql" from the following part of "/etc/init.d/orthanc": >>>>> # Should-Start: postgresql # Should-Stop: postgresql <<<<< provided that the 2 following conditions are both met: (1) Orthanc uses SQLite OR an external PostgreSQL server, AND (2) the local "postgresql" package is installed. Upgrading the Orthanc database ============================== [ This section was contributed by Karsten Hilbert . For more context, check out the Debian issue #829380 (orthanc: please provide orthanc_upgrade script). ] As explained in the Orthanc Book, the schema of the Orthanc database has evolved over time: https://orthanc.uclouvain.be/book/developers/db-versioning.html The latest versions of Orthanc still use the same schema as Orthanc 0.9.5, that was released back in December 2015. If you need to upgrade an Orthanc server from some version < 0.9.5, you'll have to start the new version of Orthanc with the "--upgrade" command-line argument: https://orthanc.uclouvain.be/book/users/replication.html#upgrade-the-database-schema The script "/usr/sbin/orthanc_upgrade.sh" automates this call.
