Before we begin, I'd like to mention that I am by no means an Ensemble expert, so take this with a grain of salt and please feel free to offer any suggestions for improvement. That being said, I have enjoyed working with Ensemble and wanted to share the approach I took to poll an external REST API for patient data in the hopes that it might help others with a similar goal.
Many mobile applications that enable users to get information about road fines and pay them, send notifications about newly added fines. This functionality can be efficiently implemented using push notifications sent to users’ devices.
Our application was not an exception. The server side is based on the Ensemble platform that offers integrated support of push notifications starting from version 2015.1.
Below is a simple alert processor based on the EnsLib.HTTP.OutboundAdapter to send text alerts via an SMS Gateway service. Typically, all that is needed to send an HTTP Post to the gateway service is the destination phone number, a source phone number, credentials, and the URL.
The code below is based on the Anveo gateway whose interface is as follows:
Framing refers to the characters that mark the start and end of an HL7 message (or other types of framed messages). Most HL7 services and operations have a Framing setting that allows the user to define this framing. The most common choices are available as defaults, but with the AsciiMM/NN setting, components can be configured to recognize any framing characters.
This short article was motivated by a problem of one of my customers. They use Ensemble to integrate many systems, some of them use just plain files.
So they naturally selected File Outbound Adapter to write into target file. Things were running smoothly for years, until recently, when the volume of data being written to the file reached large size of tens of megabytes. The operation took around half an hour to complete, causing timing problems where subsequent operations within the process had to wait, and third party system was not happy to wait so long.
When calling out to web services there are several settings of the Business Operation that play together in controlling what will happen when a response is not returned in the desired time.
We are sometimes asked for examples of how to do 3rd party SQL database selects/updates/inserts/stored procedures from an Ensemble SQL Business Operation.
In the attached file there are 4 sample Ensemble Operations that demonstrate four different types of transactions with an external SQL DB:
In Ensemble 2016.3 ‘Java Business Hosts’ provides the means to create new Business Services and Business Operations using Java without need for any ObjectScript coding. There are two major reasons to use this capability:
