wso2 esb 连接超时调优

Question

配置： WSO2ESB 4.8.0\4.8.1 操作系统：Linux\FreeBSD

CLIENT <-> ESB <-> BACKEND

这是我的问题： 如果我为示例服务创建最简单的直通代理，该代理以> 60 sec 的延迟响应。当 esb 关闭与客户端的连接而没有任何响应时，我收到错误消息。顺便说一句，根据soap tracer日志，ESB从后端接收数据，但连接"CLIENT <-> ESB"当时已经关闭。

我尝试设置这些值：

存储库/conf/axis2/axis2_client.xml

    <transportSender name="http" class="org.apache.axis2.transport.http.CommonsHTTPTransportSender"
            (...)
            <parameter name="SO_TIMEOUT">120000</parameter>
            <parameter name="CONNECTION_TIMEOUT">120000</parameter>
        </transportSender>
        <transportSender name="https" class="org.apache.axis2.transport.http.CommonsHTTPTransportSender">
            (...)
            <parameter name="SO_TIMEOUT">120000</parameter>
            <parameter name="CONNECTION_TIMEOUT">120000</parameter>
        </transportSender>

没有运气。 测试后端 URL：http://rzrbld.ru/timeout/index.php（硬编码 70 秒超时）

Answer 1

由于您使用 nhttp 作为传输，因此在 nhttp.properties 中添加 [1] 和 [2]

[1] 和 [2] 将帮助您在服务器端和客户端分别定义超时

[1]http.socket.timeout.receiver = 侦听器的套接字超时 [2]http.socket.timeout.sender = Sender 的套接字超时

示例 [1] http.socket.timeout.receiver=120000 [2] http.socket.timeout.sender=120000

Answer 2

在 nhttp.properties 中增加 http.socket.timeout 将无济于事，因为 ESB-4.8.X 默认使用 passthru 传输。请将 http.socket.timeout=600000 添加到 ESB_HOME/repository/conf/passthru-http.properties 文件并重启服务器。

Answer 3

传递代理使用默认配置的匿名端点，您应该尝试添加和使用可以配置超时的命名端点。

另一种解决方案是使用标头“To”并发送中介。在这种情况下，应该考虑使用 http.socket.timout 配置的超时时间：

<header name="To" value="http://host:port/xxx"/>
<send/>
