Hey Scott.

If you were open to having a Service in your production which is what your function sends its two variables (and the service then passes it onto your Operation) you could have something like this:

ClassMethod SendPage(PagerNumber As %String, Message As %String) As %Status
    //The String passed to Ens.Director must match a service name within the active production
    set tsc = ##class(Ens.Director).CreateBusinessService("Pager From Function Service",.tService)
    if ($IsObject(tService))
        set input = ##class(osuwmc.Page.DataStructures.Page).%New()
        set input.PagerNumber = PagerNumber
        Set input.Message = Message
        set tsc = tService.ProcessInput(input)
        Quit tsc
    Quit 0

and then you have a custom service that looks a little like this:

Class osuwmc.Services.PageService Extends Ens.BusinessService
Property TargetConfigName As Ens.DataType.ConfigName;

Parameter SETTINGS = "TargetConfigName";

Method OnProcessInput(pRequest As osuwmc.Page.DataStructures.Page) As %Status
    set tsc=..SendRequestAsync(..TargetConfigName, pRequest)
    Quit tsc


Then when you add the service to your production (remembering to match it to the name declared in the service code), you can select your target operation as a config item, and when the function is triggered it should go Function -->Service-->Operation.

Edit: my Service Class example had an error in the SETTINGS parameter, I have corrected it. 

Hey Scott.

I think you can achieve this by setting the second parameter to a comma delimted list of the request names, and then pass each value afterwards (in the same order you have the names).

For example:

Method Sample(pReq As osuwmc.Page.DataStructures.Page, Output pResp As %Net.HttpResponse) As %Status

    Set FormItems = "PNo,PMsg"
    set tSC = ..Adapter.Post(.tResponse,FormItems,pReq.PagerNumber,pReq.Message)

    if ('tSC)




    quit tSC


Hey Mufsi, I had this happen to me and according to WRC this is a known issue fixed in 2020.1.1.

It is caused by an attempt to get an exclusive lock on a specific node for the mirrored database (which is read only) where the task is being scheduled.

There is an alternative workaround to the steps you took by using the ^TASKMGR interface from the %SYS namespace in a Terminal session as it doesn't try to perform any write operations on the read-only mirror databases.

Just to expand on Davids response - the File Outbound adapter will create a new file per message assuming the filename settings are configured so that the filenames it produces are unique per message.

If you were to set the Filename property to a specific value rather than use the timestamp specifiers (so for example set it so that the filename is output.txt) then each message should write the data at the end of the file, giving you a single file with all of the entries.

You won't be able to do this using the built in viewer, however you can query the sql tables directly and then interrogate the results using your preferred method.

For example, I had a spike in activity on the 20th of Dec which made a disk fill a lot more than usual, but the purges meant I couldn't just check the messages as they had since been deleted. So I ran the following in the SQL option in the management portal:

FROM Ens_Activity_Data.Days
Where TimeSlot = '2020-12-20 00:00:00'

I then used the print option to export to CSV to then use a simple Pivot table to work through each Host name to see what had a dramatically higher number of messages to what I would usually expect. (I actually exported a few days worth of data to compare between days, but hopefully you're getting the idea)

You could always explore using Grafana to produce a nice visual representation of the data that you've surfaced using a method like this.

Hey Werner.

I know I have ignored your request on how to call a class method (Jeffery has you covered by the looks of things), but you could use $PIECE to break the string apart and then insert what you need.

For example if "source.{PhoneNumberHome(1).Emailaddress}" is equal to "myemail@myemaildomain.co.uk" then 


will return: 


The idea being that we

  • Start the new string with "test"
  • take everything before the first period with $P(source.{PhoneNumberHome(1).Emailaddress},"."1) 
  • Add "test" in again
  • Add a period that gets dropped from the $PIECE from using the period as the delimiter
  • Provide everything from the second period onwards with $P(source.{PhoneNumberHome(1).Emailaddress},".",2,*)

Hey ED Coder.

There are built in classes to manage this in a nicer way.

##class(Ens.Util.Time).ConvertDateTime() is a good starting point. For example:

Here is the filled in classmethod call for easy copy/pasting:

Set NewDate = ##class(Ens.Util.Time).ConvertDateTime(HL7Date,"%Y%m%d%H%M%S","%Y-%m-%d %H:%M:%S")

The values for each section of the date are defined by the following: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

Hey Ahmad.

If this is all happening in the one production, then you will have an inbound service for each port.

You could setup a router with a specific rule for each destination, and then use the rule constraint to be restricted on the source service. That way, if you point all three services at the one router, it will only use the rule within the router that has the service listed as a constraint.

For example:

I hope that helps!

Hey, this should be controllable using the Service setting of AckMode:

Control of ACK handling. The options are:
  • Never: Do not send back any ACK.
  • Immediate: Send back (commit) ACK reply message immediately upon receipt of the inbound message.
  • Application: If message passes validation, wait for ACK from target config item and forward it back when it arrives.
  • MSH-determined: Send back ACK reply messages as requested in the MSH header of the incoming message.
  • Byte: Send back an immediate single ACK-code byte instead of an ACK message. Byte ASCII code 6 = 'OK', ASCII code 21 = 'Error'

In your case, you'll be interested in the Application ACK.

So if your HisEmrRouter is running with 10 jobs, which then sends to ADTRoutingRule that has half the number of jobs available, then I can see that this would introduce some form of a bottleneck.

It's worth considering the impact of increasing your app pool beyond 1 when working with healthcare data, and the details of which are noted here: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

It also mentioned not having the poolsize exceed the number of CPU (I assume it means CPU cores) , however this has been contested in the past by other users as seen by the comments of Eduard here: https://community.intersystems.com/post/ensemble-introduction-pool-size-...

If FIFO is not required for your use case, I would at the very least try setting the poolsize to the same value.

Hey Yone.

It doesn't look like There was an ORU^R30 in the standard until HL7 2.5, so that would explain why there isn't a schema.

Depending on your source, you might want to look at how the source system thinks it is providing you a v2.3 ORU^R30 as it's possible they're using the 2.5 schema and then incorrectly calling it 2.3 in the header.

If that is the case, you could create your own schema based off of the 2.5 ORU^R30 to match what you're receiving.
