Decoding Base64 PDF File

Hello, I am writing some cache code that will pick up a PDF file, Base64 encode the contents and then send on to a third party system within a Long String (via their API). I have been testing this and discovered that the PDFs do not open within the supplier system (I get an error saying that it hasn't been decoded correctly). I wanted to prove that the issue does not lie with the way that I have Base64 encoded it within Ensemble, and therefore as a test wanted to Encode the PDF stream, then decode the stream and write out to a new file.

InterSystems has corrected a defect that can lead to missing resource data in FHIR search results.

This problem exists for:

  • HealthShare Unified Care Record 2020.1.0 b7015

This defect occurs due to an incorrect resource being deleted from the search index. Subsequent FHIR Resource requests against the FHIR Repository may return incomplete results due to that missing index. Any type of FHIR resource data can be lost, and depending on when the defect occurs, the same FHIR request could return different result sets.

Linux Server or Windows Server

We are in the process of using Ensemble for HL7 translations, and wanted to know is it better to use it on Linux Server or Windows Server? We are mostly a Windows shop but just wanted to make sure there is nothing we will be missing out using the Windows application.

Morning everyone,

I would appreciate some advice please- hopefully there is plenty of experts out there.

We are setting up an sFTP share between hospital trusts here in the UK and I have set the outbound operation up using a custom extension of EnsLib.HL7.Operation.FTPOperation.

We are configuring a VPN tunnel to run between the sites also so there is a bit of firewall / network routing to take place to enable the connection but to add in a complication we are on a mirrored cluster and usually present on a Virtual IP address.

I would like to know if there is a way of having a callback or something similar, on persistent classes that is always called after the execution of the operation (failed or successfull).

%OnOpen is executed prior to the action, and there is no post callback

%OnAfterDelete and %OnAfterSave are executed after a successfull operation

Dear All,

I would like to block ADT_A18 and ADT_A47 HL7 2.3 messages with an empty MRG:1 field.

This is to prevent my current HL7 ADT router (Business process) sending blank Merges downstream.

I've attempted to create a business rule where this would return out the business role process. However the messages still loop though the other rules.

Any advice would be great.

Kind Regards

Stuart

Ignore BREAKs

Hi!

I'm running a unit test via terminal, and sometimes someone from another team/squad add a few BREAKs and my tests stop until I skip one by one.

Is there a way to ignore BREAKs?

Hey,

I am pretty new to Docker and everything around that. I installed the container image from DockerHub and followed the instructions (https://hub.docker.com/_/intersystems-iris-data-platform/plans/222f869e-567c-4928-b572-eb6a29706fbd?tab=instructions). Everything is working fine except for the part where I want to change the default password.

Was wondering if anyone had a simple way of calling ##class(Ens.Director).EnableConfigItem() within a Business Process or adding code to a Custom Service to start or stop the object?

The use case is that I have a Process that uploads a file into a external SQL table. When it is finished I want it to kick off another Service that does the processing of the data that it just uploaded. Once it is finished the response is sent back to the service and when the service receives the response from the process, I want to stop that service from running.

so...

Hello everybody,

In the documentation I read the following:

Alerts are messages generated by production components. InterSystems IRIS automatically writes the alerts to a log file and sends then to the production component named Ens.Alert. If your production does not have a component named Ens.Alert, then InterSystems IRIS writes alerts to the log file but does not send them to any component. The component named Ens.Alert can be of any class. The most frequently used classes for Ens.Alert are:

DTL vs. ObjectScript

As I've become a little more familiar with HealthShare, I'd like to start exploring different ways of doing things. To date, the bulk of my data transformations have been using DTL; only using ObjectScript for a few operations that write to external SQL tables that were largely based on examples provided by my sales engineer.

Get STACK of another process

Hi,

How can I read the stack of another process?

I know about ^JOBEXAM, but I only know how to use through terminal, and I need to get a string, or at least do a method that returns me a string

For example:

I have process A and B

B monitors process A at each second.

B logs information about process A in a table

Informations about lock I get through %SYS.LockQuery and the process through %SYS.Process

Hello,

We would need to know the Ens.Response SourceConfigName to identify which Operation has raised an exception.

We have tried:

$$$LOGINFO("..%Process.%PrimaryResponseHeader.SourceConfigName..: "_..%Process.%PrimaryResponseHeader.SourceConfigName) //It outputs an empty string
 
$$$LOGINFO("response.SourceConfigName: "_response.SourceConfigName) //It generates an exception

We would need to get from an Ens.Response which body is null, its SourceConfigName:
