Hi all,

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!

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.

I need to deploy an Ensemble production to several different clients.  Each client requires certain production settings to be set specific for them, things like pool sizes, IP addresses, SSL configurations, etc.

What is the best way to customize configuration settings when a production is deployed?

Is there any issue with using a pool size setting greater than 1 for an  inbound file service? The reason I ask is we can easily dump 100k+ files to a folder in minutes, but using a pool size of 1 can take hours for that backlog to clear.

Hi All

 

I have a BP which has a transformation. 

when I run the process I end up with the following error: 

----

ERROR <Ens>ErrBPTerminated: Terminating BP Propirion.BP.GetServices # due to error: ERROR <Ens>ErrGeneral: Object is immutable
+
ERROR <Ens>ErrGeneral: Object is immutable 

----

I have created a context named : HL7Message  type of: EnsLib.HL7.Message  and in the start of the BP assigned the request to it  (using set in assigned activity)

 

What did I miss ?

 

Thanks 

Gadi

Some time ago, I was started to work at a new company even in other country, and more important in a different sphere when I have not been worked before, in HealthCare. It's a very new project even for company. Since I have not experience in HealthCare, I looked at what I can use in my project, and found that I should not reinvent the bicycle, and think about how to store all my data which I need and how to get access to this data. And I can use FHIR, which is looks like everything what I need, what else I need it's just a client.

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.

Hi

I do not really have much information yet about an upcoming mission but i know it is about to seal a flatfile and then send it further. I think  SHA256 HMAC will be used. There is a fixed sealkey to be used each time. Does anyone know if the Ensemble supports this ? I have looked in the documentation but not really found anything .

Regards,

Michael Lundberg

Hello everyone,

Does anyone know how to create integration tests using the Cache unit test framework in order to test an Ensemble production?

For example, what would be the best way to create automated tests for a BPL that calls multiple business operations (SQL, WebService ...)?

Should we create some kind of mock service/operation to simulate the response from the business operations ?

The FT keys InterSystems currently make available to us in the zips from the download pages are due to expire at the end of this month (31-Aug-16). Will there be new keys soon?

Also wondering when we might expect new FT builds for 2016.2 and 2016.3. The last published ones were 24-Jun-16 and 16-Jun-16 respectively.

I haven't seen an Atelier update for a while either.

Is there an out-of-the-box or accepted standard method for loading up mappings between different code sets and then referencing these mappings (both directions) from DTL? First thought was the built in Lookup() and corresponding data tables but these only work in one direction (key -> value) and not the reverse. Obviously I can build my own classes to support a two way mapping but am wondering if there's a standard way of achieving this. The mapping should contain the code and display name from each of the code sets and allow mapping based on either code or display name.

Thanks

We have an incoming ADT adapter and the ACK MODE is set to IMMEDIATE.  This is what the docs say: 

Send back (commit) ACK reply message immediately upon receipt of the inbound message.

 

An inbound ACK shows up as a square in the visual trace.  These do not.  How can I view them?

I have the following Ensemble request:

Class MyApp.MyRequest Extends (%Persistent, Ens.Request)
{
Property idToTokenArray As %ArrayOfDataTypes;
}

On SMP Testing service page it looks like this:

But my attempts to set idToTokenArray have not yielded any positive results so far. How do I need to fill it?

Hello community,

I have productions running in several different namespaces.  They all use a common credentials ID for sending email, which is set up in only one of the namespaces.  The documentation says that credentials are entered by namespace.  When I ran a production in a second namespace, the error log said that credentials were not found (expected), but later attempts to send a file thorugh the production did successfully send an email.  I'm wondering if Ensemble is able to look in other namespaces for the same credentials ID?

We are using the Ens.Alert alerting process to send alerts (via email) to our external service desk application (Service Now). 

Is there a way to suppress multiple alerts for the same error (within a specified timeframe)? (Either Rule or BPL?)  (i.e.  a system starts sending bad data which fails validation or is NAKd by a downstream system -- causing every message to create an Alert.)

Otherwise, every message creates an Alert, which creates a ticket in Service Now.  

 

Thanks,

 

Brian

At the Global Summit several folks had mention that they developed their own production monitor. I am looking to create a monitor similar to eGate that we only display those Services/Processes/Operations that are in trouble, and those Errors that are showing up in the Event Log. Does anyone have any examples of this?

Thanks
