Open a sisHYD project

If a sisHYD project is opened with data storage in Oracle, sisHYD offers to automatically convert the project.

If the question is answered with “no”, the project opens as before and uses Oracle for the data storage. The question is not asked again for this project.

If the question is answered with “yes”, the project is transferred to the project converter for conversion.

Project converter

The following converter exists for the conversion of “sisHYD projects with data retention under Oracle” to “sisHYD projects with database file”.

If the converter is started from a sisHYD project (File > Convert project), only that project is closed and only that project suggested for conversion.

• Add projects – Permits the selection of a folder which is scanned for sisHYD projects. The search can be terminated by clicking on “cancel”. Found projects are listed and selected (released for conversion).
• Delete selection list – Empties the list of the sisHYD projects found.
• Convert – Starts the conversion for the selected projects. The conversion takes places as follows:
  • Only the projects which are selected in the project list are converted.
  • Projects with outdated database schema are first saved with Oracle export before the Oracle database schema is updated. Finally, they are migrated.
  • The progress of the conversion work is documented in the message range and any problems are announced.
  • When a project migration is finished, sisHYD archives are created which can be read by previous sisHYD versions.
  • If a project is successfully converted, it is removed from the list.
  • The conversion can be terminated by clicking on the “cancel” button.
    • If errors arise during the conversion, the project remains intact and continues to use Oracle data storage – identifiable by the text [ORACLE] in the title bar of the application window.
• Cancel – Button to terminate process started in the background (search, conversion).
• Further remarks – The Oracle data are not changed by the conversion, i.e. if unexpected errors should arise, the raw data is still available.

Edit project

When a sisHYD project is opened, a local copy of the database file is created. The copy is copied back into the project folder when the project is closed.

When a project is opened, sisHYD creates a check file in the project folder, in which a session number, the login name of the user and the computer name are saved. During the project session, no other user can access the project as long as the file is in use.

Note: The software works faster on the local database copy.

Note: The database file is located in the project directory under the name sishyd.sdb.

Continuation after program crash

If the program crashes, the interrupted session is suggested the next time you choose “Open project”.

• Select “yes” to continue the interrupted session. Thus, you keep changes made before the crash.
• Select “no” to reject the last session’s changes.
• Select “cancel” if you do not want to open the project.
