J'ai un flux CEP qui a un débit élevé avec plus de 100 messages par seconde.WSO2 CEP 420 JMSEventAdapter - Le saut d'événement dans la file d'attente de travaux de l'adaptateur de sortie est plein
Et je publie le résultat de mon traitement dans un éditeur JMS avec la configuration suivante:
Output Event Adapter Type* : JMS
JNDI Initial Context Factory Class: org.apache.activemq.jndi.ActiveMQInitialContextFactory
JNDI Provider URL *: tcp://localhost:61616
Connection Factory JNDI Name *: QueueConnectionFactory
Destination Type *: Queue
Destination *: myqueue
aussi, afin d'essayer si le problème était de ne pas avoir accès simultané i ajouté:
Concurrent Publishers: Allow
au JMSPublisher
et je reçois l'erreur suivante:
ERROR {org.wso2.carbon.event.output.adapter.jms.JMSEventAdapter} -
Event dropped at Output Adapter 'kpis' for tenant id '-1234',
Job queue is full, Task [email protected]
rejected from [email protected]
[Running, pool size =1, active threads = 1, queued tasks = 10000,
completed tasks = 176986]
java.util.concurrent.RejectedExecutionException: Task
[email protected] rejected from
[email protected][Running, pool size = 1,
active threads = 1, queued tasks = 10000, completed tasks = 176986]
Existe-t-il une limite sur le débit d'un activemq JMS?
Aussi, jusqu'à présent, il n'y a pas de consommateur dans la file d'attente à laquelle j'écris tous les messages. Cela peut-il avoir un impact négatif sur l'éditeur WSO2 CEP causant cette erreur et dégradant les performances?
À la lecture de certaines informations en ligne, il semble que cela pourrait être un problème direct avec la taille de la piscine!
Est-il possible d'augmenter la taille du pool JMSEventAdapter? si oui, alors comment?
