We're in the process of creating several courses for creating custom business components for productions. This includes custom business operations, BPL processes, and custom business services. Custom Business Operations and Custom Business Services are both aimed at software developers while BPL processes can be also be created by business analysts. What are some gotchas or best practices you've learned that you wish you knew when first building these components?
We'd love to include what you've learned into these courses so others can learn from them as well!
I have a process that I am trying to duplicate from SQL Integration Services (SSIS) into Ensemble so that the rest of my team can help support any issues that may happen.
This particular job creates multiple dictionary files, but for each one of the dictionary files it creates, it also creates a control file that tells the vendor what to process.
Can we use Functions and Methods with multiple parameters and refer objects by reference as parameters inside Routing rule ?
How do we handle DB related workflows in Business Rules ? How can we perform Response object based handling in Business Rules ? Can we try by extending methods with Ens.Util.FunctionSet and pass in the Context object from the rule as a parameter for certain functions ? Can we split the Business Operations into methods that can be used from the routing rules and create the message route request flow ?
We would like to retry message so that it's restored to end of operation's queue. This is in situation where order of messages is not needed to be handled by Ensemble, there is version number in message data and receiving application can ignore incoming message if necessary.
We would try to send message until it's accepted (or manually suspended), but this should not block operation's queue.
We have already this in actions:
D - Disable the Operation, log an error and restore the message to the front of the Operation's queue.
I am currently working on an interface that needs to communicate to a SOAP/ITK endpoint.
I am using the EnsLib.ITK.AdapterKit.Operation.SOAPOperation to interface with an ITK service, but it is proving to be more complex than originally expected to set up the web client against that particular end-point since I haven't been provided with a WSDL from ITK service side as the vendor state they are following the ITK standard and no WSDLs are needed.
I had attempted to create a REST Operation before but did not have success. As I am going through the Tutorials and Documentation everything references REST services, but I have a case where I want to create a REST Operation that makes Epic API calls against Interconnect. I have done SOAP operations before and we currently have one in our Production Namespace, but from what I understand SOAP has the wsdl which defines al the structures and etc, where REST does not.
Is their a way to queue messages in a business operation to be processed later? I want to process messages over a certain size on a schedule, but let everything else process in real time. Is their a way to do this with one business operation or would I have to queue the large messages in a different business operation?
I have several stored procedures that when I execute them they will only return a single snapshot. In my BP I have been setting this to a Snapshot variable then looping using a WHILE through the snapshot variable just to get that single value.
Since it is only a single row, is there an easier way where I don't have to do a WHILE loop to pull the values out of that row? Can I call First Row or something like that to get me just the row into the Snapshot variable?
Trying my first REST call operation to our internal EMR (Epic) server, and I am receiving "ERROR #6097: Error '<READ>Read+28^%Net.HttpRequest.1' while using TCP/IP device '9999'" when I attempt to test my operation. When I look up the General Error Messages for 6097 I am seeing...Error '%1' while using TCP/IP device $zu(189,1)='%2'. What does this mean?
First time setting up a SSL/TLS connection, and I am running into issues when I call it from within a Business Operation. I used openssl to generate a RSA 4096 SHA512 key/csr request for our Active Directory Certificate Service to generate a Certificate Chain for me to use within RedHat. I was
able to connect to our Web Service server using a generic request from terminal, however when I try it from our Business Operation I am running into issues.
I tested the SSL/TLS connection using the following commands from the terminal...
DEVCLIN>set request=##class(%Net.HttpRequest).%New()
I'm trying to add an Operation to store DICOM files but each time I add a Operation using the class EnsLib.DICOM.Operation.TCP it reverts into Services and I cannot work out why this is happening. I've tried following the guide online (link at the bottom) but the Operation still reverts to a Service.
I'm trying to establish a communication between my edge, which is in one server, with my HUB which is in another one. In EDGE, when the HS.Gateway.HSWS.WebServices component sends a message to the HUB component, it receives the following error: "Cannot invoke method RegisterGateway; WebServiceClientClass 'HS.Hub.HSWS.WebServicesClient' could not be instantiated, or the WebServiceURL Location could not be determined".
I'm working with a REST API that will sometimes rate limit our requests by returning an HTTP 429 Too Many Requests status code. Is there a good way in a business operation to handle this by throttling our requests until we get a success response? My initial thoughts are:
I created Business Operation in my ENSDEMO namespace that will connect to an external REST endpoint to send data to this external REST Service.
I also created an http service in Home>Healthshare>Service Registry, under the Service Type: http. I entered the REST endpoint Name, Host, SSL Configuration, and URL.
We have just completed a migration of a test environment from Ensemble 2012 to Ensemble 2017 on a new server. This is the last in a series of migrations but the first to encounter this particular issue. All web clients making SOAP requests to a particular external web service are receiving a fault that states:
The SOAP action specified on the message, '', does not match the HTTP SOAP Action, 'http://<expected target service action follows here>'.
I have a production that writes x12 file with a EnsLib.EDI.X12.Operation.FileOperation. I am trying to get file name that was used back to the business process. What is the best way to do this?
I just deployed my production from test to acceptance but I found that the deployment misses some Soap Webclient classes which are used by my business operation components. I have used the management portal to create the deployment (i.e. production settings -> Export) and I expected that all classes used by the production were automatically included. Apparantly, that is not the case. Is this default behaviour for Ensemble? And can I somehow force Ensemble to automatically include these classes?
I'm writing a SOAP client in Ensemble (2017.2.2) that is required to pass empty elements to the SOAP server in the form <xsi:type="ns:ResponsibleUser"/> where ResponsibleUser is a class that itself has no properties. I initially thought I'd found the answer with the XMLIGNORENULL parameter of XML enabled classes but this didn't make any difference for SOAP requests, only working when I wrote the XML to a file.
