Bonjour.

J'ai plusieurs applications web déployées sur le serveur par défaut de WAS. L'une d'elle lance régulièrement un traitement de sérialisation, découpage d'un flux XML qui prend pas mal de ressources.
Le 1er lancement suite au démarrage du serveur se passe toujours bien. Les suivants plantent en OutOfMemoryError alors qu'ils sont identiques au 1er.
En arrêtant et relançant le serveur, ce traitement fonctionne de nouveau correctement.

C'est d'autant plus bizarre que ce genre de traitement, en beaucoup plus lourd (avec des flux bcp + volumineux) se passe sans problèmes sur d'autres serveurs d'appli (WAS5 Tomcat etc..)
Je ne sais pas si c'est lié à WAS6 ou aux autres applications installées sur le serveur mais je ne sais pas ou diriger mes recherches.
Y'a-t-il de la mémoire mal libérérée par une de ces applis?
Existe-t-il sous WAS des informations qui pourraient orienter ma recherche?

J'ai par ailleurs alloué + de mémoire à la jvm utilisée par le serveur (Xms Xmx) sachant que cela n'est pas utile sur les autres serveurs d'appli, mais ça ne change rien.

[trax020]

Je vis ce calvaire aussi, avec WAS 6.0
Si tu es sur une piste, merci de nous en faire part...

Up !

Hi,

Tu peux essayer deux outils qui devraient te donner pas mal d'information et de nouvelles pistes pour resoudre tes problemes,

• Tivoli Performance Viewer (un outil fourni avec Websphere AS normalement)
• Utiliser un profiler soit celui fournis avec les outils de developpement Websphere ou Rational, soit OptimizeIt qui est assez bien fait.

Peut-tu donner le message d'erreur du OutOfMemory? et la configuration des arguments de la JVM?

Sinon une technique bien pratique et peu connus consiste a modifier la taille de la Heap Size (je te laisse chercher ce que c'est, mais c'est en gros l'endroit où java crée ses objects)

Dans les arguments de demarrage de ton server d'application (pas celui d'administration celui utiliser par l'application) ajoute l'argument suivant: -XX:MaxPermSize=256M

J'espere que cela pourra t'aider.

J'ai le même problème.

Utilisez-vous hibernate? J'ai l'impression que c'est associé.

Voici mon log :

Voici ce que j'ai trouvé :

1)
Augmenter le "heap size" dans la configuration du serveur:
Admin console > Application server > server1 > Java and process managment > Process def > Java virtual machine

Initial heap size = 384
and max size = 1024

2) (solution à la 6-4-2 mais bon...)
Mettre en commentaire les mapping que l'on utilise pas pour le développement en cours dans : hibernate.cfg.xml
