I want to start this project and wants to know the best practices, you guys using to arrange the project. I have done lot of mvc projects and API's in c#. But Intersystems is new to me. Please give me some suggestions like how can I Arrange the objects. Like for eg. Where can I store the productions objects like services,process and operations. will that be like under each resouces folder name? and what are the base classes, and how can I store them? basically please give me some idea about how Can I arrange them .

Bookkeeping in Business Operation

In my Business Operation I need to execute a bookkeeping method every X seconds.

How can I do that?

There are two workarounds (I dislike both):

  1. Execute bookkeeping on process start - but there might be no requests at all
  2. Create a BS that sends messages to BO every X seconds - it makes production more complex and also queues might not guarantee that the method is executed on schedule.

Thoughts?

Interoperability with IRIS and Pharmacy Robotics

I have attached a document that describes the product I have developed called NiPaRobotica Pharmacy. This is an interface I developed that accepts Pharmacy Dispense Requests and converts the line items on the order into dispense dialogues which it sends to pharmacy robots. I deployed the interface into 3 Hospital pharmacies two of which had 6 robots that were arranged in such a way that the dispense chutes channelled medications to desks by the pharmacists sitting in windows serving 1200 patients a day. The robots cut the average waiting time from 2 hours down to one hour.

Interoperability Alerts - routing and aggregating

Alerts are automatic notifications triggered by specified events or thresholds being exceeded.

InterSystems Documentation

I have a Business Service connected to a machine with ~100 sensors. BS receives sensor values once a second.

Several conditions determine if a Business Serviceshould raise an alert (it's a list of: sensor id > threshold).

I have three questions:

  1.  Should I write these conditions as a business rule and call this rule from the Business Service, and if the rule returns 1 call SendAlert? Or is there some other way to do that?

IRIS Interoperability Message Bank

I heard about Message Bank when we started redesigning a Health Connect production to run in containers in the cloud. Since there will be multiple IRIS containers, we were directed to utilize Message Bank as one place to view messages and logs from all containers.

How does Message Bank work?

I added Message Bank operation to our Interoperability Production. It automatically sends messages and event logs to the Message Bank.

Resending Messages

The Message Bank provides an interface for portal user to resend messages from the Message Bank portal.

Mirroring Ensemble service information

I have some system with heavy production. There are about 500GB of journals daily. And I'm looking at the ways, how to decrease the amount of data that appeared there.

I found no way, on how to split have the journal separately for mirroring databases and for others. So, I'm thinking about moving some of the globals to CACHETEMP. So, they will disappear from journals. So, thinking about Ens.* globals, I have about 30% of data in journals just for such data. Which production data can be safely moved to CACHETEMP, with no issues for mirroring?

Updating active Business Processes

I have a BPL Business process which always processes messages - mainly it waits for responses since downstream systems are seriously async.

I need to update this process.

Wwould the existing instances of this Business Process complete correctly after the update?

My BPL changes would result in:

  1. New S method in the Thread class
  2. New OnResponse method in the context class

Both changes are in the middle of the process, so there are S/OnResponse methods before and after my change.

What if it's only a new S method? What if it's only a new OnResponse method?

Try out InterSystems FHIR Transformation Service - we want your feedback!

Hello Developers!

Have you ever had to convert HL7v2 messages to FHIR (Fast Healthcare Interoperability Resources) and found the process complicated and confusing? InterSystems is rolling out a new cloud based SaaS offering called InterSystems FHIR Transformation Service, which makes the process easy.  We are excited to announce an Early Access Preview Program for our new offering, and we would love to have you kick the tires and let us know what you think!  All you need is a free AWS account, with an S3 bucket to drop in your HL7v2 messages, and another S3 bucket to get your FHIR output.

Creating a PEX Business Operation

PEX is a new InterSystems IRIS feature to allows extends IRIS with existent features from Java or .NET.

It is possible create interoperability inbound and outbound adapters, business services (integrate from external to internal) and operations (integrate internal to external).

To create a PEX component it is necessary import .NET (InterSystems.EnsLib.PEX.*) or Java (com.intersystems.enslib.pex.*) packages and extends or implements the properly class.

In this article I will use my OCR Service.

Calling production from a REST Broker

Productions often need to receive REST requests.

Here's how to do that.

1. Create proxy Service:

/// Empty BS we would use to send Produciton requests
Class production.ProxyService Extends Ens.BusinessService
{
}

2. Add it to production as RESTService (or any other name).

3. Write your rest broker (docs, )

4. In your handler method create the message and call target BP/BO like this

Include Ensemble
Class test.REST Extends %CSP.REST
{

XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>
<Route Url="/launchProcess/:processName" Method="POST" Call="launchProcess"/>
</Routes>
}

ClassMethod launchProcess(processName As %String) As %Status
{
    #dim sc As %Status = $$$OK
    
    // BS from which we would call BP
    #dim serviceName As %String = "RESTService"
    
    #dim message = ##class(Ens.StringContainer).%New(%request.Content.Read($$$MaxStringLength))
    
    set sc = ..invokeHostAsync(processName, message, serviceName)

    quit sc
}

/// Call production host in async mode
/// Thirs arg is BS caller, testing service by default - testing must be enabled in that case
ClassMethod invokeHostAsync(targetHostName As %String, message As %Persistent, serviceName As %String = "EnsLib.Testing.Service", sessionId As %Integer = "") As %Status
{
    #dim sc As %Status
    
    #dim prod As Ens.Config.Production = ..getCurrentProduction()
    if '$isObject(prod) quit $$$ERROR($$$GeneralError, "Produciton is not running")
        
    #dim item As Ens.Config.Item = ..findConfigItem(targetHostName)
    if '$isObject(item) quit $$$ERROR($$$GeneralError, "Host " _ targetHostName _ " not found")
    
    #dim service As Ens.BusinessService
    set sc = ##class(Ens.Director).CreateBusinessService(serviceName, .service)
    if $$$ISERR(sc) quit sc
    
    if (sessionId '= "") set service.%SessionId = sessionId
    
    set sc = service.SendRequestAsync(targetHostName, message)
    
    quit sc
}

/// Get current production
ClassMethod getCurrentProduction() As Ens.Config.Production
{
    #dim sc As %Status
    #dim prodName As %String
    #dim prodState As %Integer
    
    // Get produciton name
    if '##class(Ens.Director).IsProductionRunning(.prodName) quit ""
    
    
    // Open produciton by name
    #dim prod As Ens.Config.Production = ##class(Ens.Config.Production).%OpenId(prodName, , .sc)
    if $$$ISERR(sc)
    {
        $$$LOGERROR($System.Status.GetErrorText(sc))
        quit ""
    }
    
    quit prod
}

/// Find host by name
ClassMethod findConfigItem(name As %String, businessType As %String = "", enabledOnly As %Boolean = 0) As Ens.Config.Item
{
    #dim sc As %Status
    
    // Get current production
    #dim prod As Ens.Config.Production = ..getCurrentProduction()
    if '$isObject(prod) quit ""

    // Search for our target
    #dim item As Ens.Config.Item
    #dim result As Ens.Config.Item = ""
    for i = prod.Items.Count():-1:1
    {
        set item = prod.Items.GetAt(i)
        
        if '$isObject(item) continue
        if ((businessType '= "") && (item.BusinessType() '= businessType)) || (item.Name '= name) || (enabledOnly && 'item.Enabled) continue
                        
        set result = item
        quit
    }
    quit result
}

}
