Settings for Routing Processes
Provides reference information for settings of EnsLib.HL7.MsgRouter.RoutingEngine business process, which you use to route most kinds of virtual documents.
EnsLib.HL7.MsgRouter.RoutingEngine has the following settings:
|Basic Settings||Validation, Business Rule Name|
|Additional Settings||Act On Transform Error, Act On Validation Error, Alert On Bad Message, Bad Message Handler, Response From, Reply Target Config Names, Response Timeout, Force Sync Send|
|Development and Debugging||Rule Logging|
The remaining settings are common to all business processes. See “Settings for All Business Processes” in Configuring Ensemble Productions.
If True, causes errors returned by a transformation to stop rule evaluation and the error to be handled by Reply Code Actions setting.
If True, causes errors returned by validation to be handled by Reply Code Actions setting.
If True, any document that fails validation automatically triggers an alert.
If the document fails validation, and if the routing process has a configured Bad Message Handler, it sends the bad document to this business operation instead of its usual target for documents that pass validation.
See “Defining Bad Message Handlers,” earlier in this book.
The full name of the routing rule set for this routing process.
If True, make synchronous calls for all “send” actions from this routing process. If False, allow these calls to be made asynchronously. This setting is intended to ensure FIFO ordering in the following case: This routing process and its target business operations all have Pool Size set to 1, and ancillary business operations might be called asynchronously from within a data transformation or business operation called from this routing process.
If Force Sync Send is True, this can cause deadlock if another business process is called by a target that is called synchronously from this routing process.
Note that if there are multiple “send” targets, Force Sync Send means these targets will be called one after another in serial fashion, with the next being called after the previous call completes. Also note that synchronous calls are not subject to the Response Timeout setting.
Specifies a comma-separated list of configuration items within the production to which the business service should relay any reply documents that it receives. Usually the list contains one item, but it can be longer. The list can include business processes or business operations, or a combination of both.
This setting takes effect only if the Response From setting has a value.
A comma-separated list of configured items within the production. This list identifies the targets from which a response may be forwarded back to the original caller, if the caller requested a response.
If a Response From string is specified, the response returned to the caller is the first response that arrives back from any target in the list. If there are no responses, an empty “OK” response header is returned.
The Response From string also allows special characters, as follows:
The*character by itself matches any target in the production, so the first response from any target is returned. If there are no responses, an empty “OK” response header is returned.
If the list of targets begins with a+character, the responses from all targets return together, as a list of document header IDs in the response header. If none of the targets responds, an empty OK response header is returned.
If the list of targets begins with a-character, only error responses will be returned, as a list of document header IDs in the response header. If none of the targets responds with an error, an empty OK response header is returned.
If this setting value is unspecified, nothing is returned.
Maximum length of time to wait for asynchronous responses before returning a “timed-out error” response header. A value of -1 means to wait forever. Note that a value of 0 is not useful, because every response would time out. This setting takes effect only if the Response From field has a value.
If logging is enabled controls the level of logging in rules. You can specify the following flags:
e—Log errors only. All errors will be logged irrespective of other flags, so setting the value to 'e' or leaving the value empty will only log errors.
r—Log return values. This is the default value for the setting, and is also automatic whenever the 'd' or 'c' flags are specified.
d—Log user-defined debug actions in the rule. For details on the debug action, see “Adding Actions” in Developing Business Rules. This will also include 'r'.
c—Log details of the conditions that are evaluated in the rule. This will also include 'r'.
a—Log all available information. This is equivalent to 'rcd'.
