If you have configured automatic calls for a contact, you may set a delay before placing an automatic call. If you do NOT want to accept calls from unknown servers, follow the steps above but click the Decline Calls from Unknown MassTransit Servers option in step 3 ( Require Password checkbox will be disabled). Note: Before calling another Server, make sure that the contact running the software has chosen to receive calls from unknown Servers and ask if a password is required. As a result, scripts cannot access passwords. Note: For security, MassTransit encrypts passwords before storing them. Thereafter, a password will not be required, because MassTransit will recognize the calling Server. If you check the Require Password checkbox, you can enter a password (in the field next to the Require Password checkbox) which will be required for the calling server the first time they call you. In the Server-to-Server Connections area, click the option Accept Calls from Unknown MassTransit Servers.In the Setup window, click the Special tab.To accept a call from an unknown HP Server, follow these steps: Click on the OK button in the Setup window to save the changed settings.Ī calling Server is considered unknown until added to the receiving Server's Contacts window.Verify or change the name you want to use to identify yourself to the other Servers in the Server Name area of the window.In the Setup window, select the Outgoing Calls tab.Open the Setup window by clicking on the Setup button from the Navigation Bar or by selecting the Setup.Note: This name will be used to identify you at all contacts you have. Identify Your Serverīefore connecting to another HP Server, you may want to verify the name to be used by MassTransit to identify yourself to the remote Server. Find detailed information about how to configure them below. 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.There are some very useful additional configurations that can be set. In these situations, it's best to dust off and nuke the site from orbit - at a much later time obviously. Some errors take a while to resolve, say a remote service is down or a SQL server has crashed. 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). You can use multiple calls to these methods to specify filters for multiple exception types: 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. With no argument, all exceptions of specified type will be either handled or ignored. 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. Specify exception types using either the Handle or Ignore method. 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 Retry after a delay, for each interval specified Retry after a fixed delay, up to the retry limit When configuring message retry, there are several retry policies available, including: Policy Learn how to configure message retry in this short video (opens new window).
