wso2 bps bpel日志记录和故障排除 [英] wso2 bps bpel logging and troubleshooting

问题描述

我必须管理WS2 BPS(3.6.0)，它对内部异常不是很了解. 有关问题排查的文档中有一小章 ，但是此设置仅记录传递到端点的消息.

I have to admin the WS2 BPS (3.6.0) is not very revealing about internal exceptions. There's a small chapter in the documentation about troubleshooting, however this setup logs only messages passed to the endpoints.

问题:

• 是否可以查看是在处理还是未处理的BPEL执行期间引发的内部异常? (例如表达式或脚本中的错误).也许在Apache-ODE级别上?
• 有什么方法可以访问"catchAll"故障处理程序捕获的故障?

谢谢大家的提示

推荐答案

1)解决问题的一种方法是启用BPEL运行时调试日志，您可以在其中查看执行流程.

1) One way troubleshoot is, enable BPEL Runtime debug logs, where you can see the execution flow.

log4j.logger.org.apache.ode.bpel.runtime =调试

log4j.logger.org.apache.ode.bpel.runtime=DEBUG

如果需要更多信息，还可以为ODE引擎启用调试日志.

If you need further information, you can enable debug logs for ODE engine as well.

log4j.logger.org.apache.ode.bpel.engine =调试

log4j.logger.org.apache.ode.bpel.engine=DEBUG

2)没有OTB方法可以实现这一目标.这是BPEL 2.0规范中的限制.在BPEL 2.0中，您只能捕获在伙伴服务WSDL中定义的故障.此外，您可以为错误消息分配一个变量.由此，您可以访问有关故障的信息.

2) There is no OTB way to achieve this. This is a limitation in BPEL 2.0 spec. In BPEL 2.0, you can catch only faults that are defined in the partner service WSDL. Additionally, you can assign a variable for the error message. From that, you can access information about the fault.

但是CatchAll不与变量关联.它是一个通用的故障处理程序.

But CatchAll doesn't associate with a variable. It is a generic fault handler.

我建议使用基于标志的解决方案来处理catchall中的错误. (这是我在大多数解决方案中所看到的.)

I would suggest using flag based solution to handle errors within catchall. (That is what I have seen in most of the solutions.)
