Jak naprawić błędy "Nie można uzyskać blokady po 15 sekundach" w Wildfly

Question

Mam aplikację internetową, która jest <distributable/>, ale również jest wdrażana w pojedynczych instancjach Wildfly do prac związanych z rozwojem lokalnym. Czasami mamy wywołania do zaplecza, które mogą zatrzymać się na kilka sekund, co często prowadzi do wyjątków, takich jak ten pokazany poniżej.

Jak mogę to naprawić, ponieważ nie mam wpływu na długo działające żądania backendu?

Answer 1

Uważam, że odpowiedź jest aktualizacja infinispan konfigurację jak ta, która zwiększa limit czasu blokady do 60 sekund.

<cache-container name="web" default-cache="passivation" module="org.wildfly.clustering.web.infinispan"> 
       <local-cache name="passivation"> 
        <locking isolation="REPEATABLE_READ" striping="false" acquire-timeout="60000"/> 
        <transaction mode="BATCH"/> 
        <file-store passivation="true" purge="false"/> 
       </local-cache> 
       <local-cache name="persistent"> 
        <locking isolation="REPEATABLE_READ" striping="false" acquire-timeout="60000"/> 
        <transaction mode="BATCH"/> 
        <file-store passivation="false" purge="false"/> 
       </local-cache> 
      </cache-container>
