Hi. This about  a migration of code from a DEV environment to a PROD environment.

If an (under development) business host is Enabled in DEV environment  and the production class is migrated across environments, this means that the Enabled status of the same business host in PROD would also become enabled (even if it may have been disabled before the update)

Hey everyone, 

I stumbled across a comment in this post that mentioned that the %SYS.GlobalQuery is a potentially faster alternative to %GSIZE. I tested it out and while I like the %SYS.GlobalQuery I noticed that it has some size discrepancies against a %GSIZE with details.  Can anyone tell me which is more accurate for estimating the size of globals?

Ensemble HTTP OnProcessInput

I am just trying to make a quick hand off HTTP production. I have the class built and compiled onto the server and the production is running as a service. When the production is called (by an inbound job) I can see that the HTTP.InboundAdapter is being used successfully and the stack continues all the up to ProcessInput where OnProcessInput is called in Ens.BusinessService.

I am receiving this alert every couple of minutes.  I am trying to figure out what is causing this and if it is just the settings on my TCP operation or if this indicates an actual issue.  Is it an issue with my framing (MLLP) or reply code actions (not set)?  Something else?


ERROR <Ens>ErrTCPTerminatedReadTimeoutExpired: TCP Read timeout (30) expired waiting for terminator SegTerminatorAscii=13, on |TCP|7049|12692, data received =''

Troubleshooting Disconnects

One of our Departments are claiming that we are loosing HL7 messages that are sent from their Vendor's system to Ensemble.

I know interfaces 101 if we have no record of the message then we never received it, however they are insisting they are sending it.

I asked them to provide the ACK's if they sent the messages but Ensemble had no corresponding Message Control ID (MSH.10) .

Currently I have the following settings...

Hi everybody,

I created my own REST service class by extending   EnsLib.REST.Service.

In some particular conditions of  the parameters of the request,  the REST  service should respond to the client with an HTTP status response code 400 "Bad request".

I read the article "RESTful Exception Handling "  and I try to use the suggested:

do ..ReportHttpStatusCode(400)

But the server seems ignore it and  get back to client  the 500 http response code.

Any suggestions?

Good morning,

Background to task: Shut down Ensemble from a task in Task Manager.

I have a batch file that shuts down Ensemble when run as administrator. I can confirm this works, as it brings up the shutdown/restart prompt for Ensemble, however I now need to plug this into Ensemble's Task Scheduler so it can be run on-demand.

At present I am trying to use: do ^execute: %windir%\system32\cmd.exe Z:\Scripts\shutdown.lnk

We have noticed in the course of the last 18 days our CACHE.dat has grown by 20 GB. Is there a way we can break down the data in CACHE.dat to see what could be growing in size?

Let me state it another way.....Is there a way to see what space an Operation/Service/Process is taking up within a certain Production?

Most of my development experience is with HL7v2 interfaces and I don't have a background in web development and I'm very weak with javascript.

I'm looking for suggestions of learning resources to learn FHIR  and 'SMART on FHIR' (JavaScript, OpenID connect, OAuth2) for developers like myself who mostly do HL7v2 integrations - but see FHIR as the future - and want to develop their skills!

I've found these

I have a process which is passed a .rtf within a GlobalBinaryStream. I am trying to then output just the .rtf to a folder on a server, but not even sure where to start.

Is there a Built in Operation that I can pass the GlobalBinaryStream to which will then write the file to a folder, or do I need to use a custom class for the operation?

PDFs and Reading them

I know there are numerous Java libraries available to scan a PDF meta data, but is there a way to scan a PDF using native cache object script? We are looking to take a PDF from an external vendor, scan for meta data, create the HL7 message, and embed the PDF within the HL7 message.

I'm getting mad trying to get data from an external REST service that uses Basic Authentication from Ensemble. The BO worked fine when I was using a test server without authentification, but as soon as we need to go to production I cannot have it working.

So far, I've created the username/password at the credentials page (Ensemble-Configure-Credentials). I've setup the BO to use this credentials. But nothing happens.

I've tried with the Rest Client (addon for Mozilla), and using the same address, port and user/pwd works just fine.

Hi All,

I am fairly new to Ensemble and I wanted to know I have inbound business service (EnsLib.File.PassthroughService) which is looking for pdf files once it finds a pdf file (within the business process) it needs to find the associated xml file which would be in the same directory. Once both of these files are found they need to be sent to the business operation and deleted from the source (EnsLib.File.PassthroughOperation).
