Bonjour,
J’ai un soucis de chargement des données en utilisant la commande
curl -X POST -H « Content-Type:application/rdf+xml » --data-binary @flux-10691-202105161037.rdf « http://localhost:9999/blazegraph/namespace/kb/sparql »
j’obtiens ceci :
Caused by: java.lang.OutOfMemoryError: Java heap space
Est ce que mon fichier es trop gros ?
Dois-je créer plusieurs flux ?
Merci
Bonjour,
Je tente de charger la base dans blazegraph sur ma raspberry pi sans succès.
Cela fonctionne sous windows.
J’ai ceci d’un côté :

Pourriez-vous me dire comment vérifier que la base est bien chargée svp ?
merci
Bonjour,
Vous devriez augmenter la mémoire dédiée à Java grâce aux paramètres :
-Xms512m -Xmx4g
Dans votre premier message, vous limitez la mémoire de Java à 800Mo, ce n’est clairement pas assez pour le chargement de l’ensemble des données du dataset.
Cordialement.
