PROCÉDURE
Il est recommandé d’effectuer régulièrement une compression pour garantir l’intégrité de la géodatabase versionnée. Cette opération supprime les états qui ne sont plus référencés par une version et déplace des enregistrements des tables de deltas vers leurs tables métier correspondantes. La fréquence de modification des données a une incidence sur la durée de l’opération de compression. Lors de la sortie des utilitaires 10.3 et 10.2.1 et du correctif 1 Telco, un journal supplémentaire sur la compression a été prévu pour présenter le déroulement complet de la procédure.

Remarque : Si la géodatabase d’entreprise SQL Server est gérée par un utilisateur DBO (et non SDE), changez le propriétaire des tables et passez de SDE à DBO pour déclencher l’opération.
