verify that the performance counters perfDisk,perfProc, and perfOS are not disabled.

Redelivery is a form of retry (some refer to it as second-level retry) where the message is removed from the queue and then redelivered to the queue at a future time. To avoid this exception, manually remove AGENTORACLEHOME related. In these situations, it's best to dust off and nuke the site from orbit - at a much later time obviously. Fortunately, many open source projects are leveraging log4net to provide a configurable level of runtime information that can be useful in figuring out.

One feature that is often overlooked in software development is the output of information that can be observed by operations once the application is in production. Some errors take a while to resolve, say a remote service is down or a SQL server has crashed. Performance Counters Added to MassTransit 14 October, 2009. If a DataException is thrown matching the filter expression, it wouldn't be handled by the second retry filter, but would be handled by the first retry filter. In the above example, if the consumer throws an ArgumentNullException it won't be retried (because it would obvious fail again, most likely). AddMassTransit ( x => ) Copy to clipboard You can use multiple calls to these methods to specify filters for multiple exception types: MassTransit has extensive exception handling options, including retry and redelivery, and also supports poison messages by moving them to an error queue as w. No further filtering is possible if this version is used. Non-generic version that needs one or more exception types as parameters.You can also specify a function argument that will filter exceptions further based on other parameters. Take, for example, a consumer that simply throws an exception. But before getting into that, an understanding of what happens when a message is consumed is needed. With no argument, all exceptions of specified type will be either handled or ignored. Fortunately, MassTransit provides a number of features to help your application recover from and deal with exceptions. Generic version Handle and Ignore where T must be derivate of System.Exception.A filter can have either Handle or Ignore statements, combining them has unpredictable effects. If the user credentials do not have administrative access likely they will not have the ability to create the performance counters and errors will be logged. Specify exception types using either the Handle or Ignore method. If MassTransit does not detect the performance counters it wishes to write to it will attempt to create them. To implement this, you can use an exception filter. Sometimes you do not want to always retry, but instead only retry when some specific exception is thrown and fault for all other exceptions. Retry after a steadily increasing delay, up to the retry limitĮach policy has configuration settings which specifies the expected behavior. Retry after an exponentially increasing delay, up to the retry limit 3.9K views 2 years ago MassTransit Episode Twelve covers error handling, including fault events published by MassTransit, as well as moving faulted messages to the error queue. Retry after a delay, for each interval specified
