Inspecter la base h2

les bases h2 sont interrogeable en SQL, avec un client java. l'accès n'est pas partagé et tant que geonetwork forntionne, il est impossible d'accéder à la base de données. la documentation du SQL compris est très bien faite1).

Ci dessous une copie de session montrant la base h2 /var/lib/tomcat8/geonetwork.h2.db.

  • :!: Le nom d'utilisateur par défaut est admin et le mot de passe par défaut est gnos.
  • :!: En cas d'erreur de frappe dans le nom de la base de données, une base toute neuve sera crée, sans avertissement. Ça peut surprendre.
