请教weblogic 专家

当在集群环境中采用 jdbc session persistence 的时候， 什么时候会触发 如下 语句
update wl_servlet_sessions set wl_session_values = :1, wl_is_new = :2, wl_is_valid = :3, wl_access_time = :4, wl_max_inactive_interval = :5 where wl_id = :6 and wl_context_path = :7

我的weblogic 配置如下

请问上上面那句update 语句上面时候会被执行啊 。

集群间的Session同步复制时？
