问题描述
我正在尝试调试一个BPEL流程。我使用BPEL Designer for Eclipse（3.7.2），我使用Ode 1.3作为引擎。我不知道如何调试我的进程。我可以在调试会话中将其部署到ode上，但我不明白我可以做什么。
你可以在上部署以WS-BPEL 2.0标准开发的BPEL流程。
在WSO2 Business Process Server上部署BPEL流程后，您可以使用以下机制来调试/排除故障。
1.使用Message Tracer。这使您可以查看BPS服务器的入站和出站邮件。为BPEL流程启用邮件跟踪日志;
将以下条目添加到$ CARBON-HOME / lib / log4j.properties
log4j.logger.org.apache.ode.bpel.messagetrace = TRACE log4j.logger.org.wso2.carbon.bpel.messagetrace = TRACE
应优先配置log4j appender，使其具有TRACE级别的阈值。如果CARBON_LOGFILE是log4j appender，则应更改如下。默认情况下设置为DEBUG。
eg - log4j.appender.CARBON_LOGFILE.threshold = TRACE
Re - 启动服务器。
2.使用实例信息页面中的事件表（图1）。成功执行后，每个活动都应该有3个事件。如果一个活动只有2个事件，或者如果它有一个ActivityFailureEvent，那么这个特定活动中的某些事情就会出错。您可能需要参考WSO2 BPS服务器的日志文件以便进一步调查此问题。
I'm trying to debug a BPEL process. I made it using BPEL Designer for Eclipse (3.7.2), i'm using Ode 1.3 as engine.
I have no idea how to debug my process. I can deploy it on ode in a debug session but I don't really understand what can i do after that.
You can deploy BPEL processes developed in WS-BPEL 2.0 standard on WSO2 BPS server.Once you deploy the BPEL process on WSO2 Business Process Server, you can use following mechanisms to debug/troubleshoot failures.
1.Using Message Tracer. This enables you to view the inbound and outbound messages to and from BPS server. To enable message trace logs for BPEL processes;
Add the following entries to the $CARBON-HOME/lib/log4j.properties
log4j.logger.org.apache.ode.bpel.messagetrace=TRACE log4j.logger.org.wso2.carbon.bpel.messagetrace=TRACE
The preferred log4j appender should be configured such that it has a threshold of TRACE level. If CARBON_LOGFILE is the log4j appender, it should be changed as follows. By default this is set to DEBUG.
eg - log4j.appender.CARBON_LOGFILE.threshold=TRACE
Re-start the server.
2.Using the Event table in the 'Instance Information' page (Figure 1). Each and every activity should have 3 events upon the successful execution. If an activity only has 2 events or if it has an "ActivityFailureEvent", then something must have gone wrong within that particular activity. You may need to refer the log file of WSO2 BPS server in-order to further investigate on the issue.
