Mastering the JDBC SQL Gateway

As we all know, Caché is a great database that accomplishes lots of tasks within itself. However, what do you do when you need to access an external database? One way is to use the Caché SQL Gateway via JDBC. In this article, my goal is to answer the following questions to help you familiarize yourself with the technology and debug some common problems.

Hi everyone,

I am very pleased to announce that the Readmission Demo has been released as open source. Many thanks to the Solution Factory team that worked hard on making this possible.

Transform custom healthcare messages to SDA

EHR (Electronic Health Record) systems are modeled in a proprietary format/structure and are not based on market models such as FHIR or HL7. Some of these systems can interoperate data in a proprietary format for FHIR and other market models, but others can not. InterSystems has two platforms that can interoperate proprietary formats for market ones: InterSystems HealthShare Connect and InterSystems IRIS for Health.

This article will provide tips and tricks on customizing Ensemble business hosts with configurable settings.

Ensemble production Settings are configurable values that control the behavior of a production and its hosts.

The documentation for adding and removing Settings and specifying categories and controls for Settings is provided at the link:

In this article, I will show how you can easily containerize .Net/Java Gateways.

For our example, we will develop an Integration with Apache Kafka.

And to interoperate with Java/.Net code we will use PEX .


Our solution will run completely in docker and look like this:

Diagnosing Framing Errors

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.

Good day, Developer Community!

As you know we have Company listings on Open Exchange. It lets publishing Open Exchange applications on behalf of companies so one can check which solutions in certain industries are being provided by companies.

Sometimes people are also looking for qualitative and proven implementation or consulting services on InterSystems products: IRIS, Caché, Ensemble, or HealthShare.

And recently we introduced a new option on Open Exchange to list the services your company provides related to InterSystems technology: implementation, consulting etc.

How to do that?

Open your company profile in the Services tab and create a service. Choose the type of service and give a description of what the service is about and why it is worth ordering it. Instructions.

Then publish the service by sending it for approval.

We are getting more and more request wondering if we could send/receive data via HTTPS to the outside world from within our Hospital Network. As you can imagine our Ensemble/Cache productions are not exposed to the DMZ or has access outside of the network. We only communicate with external vendors through a VPN, so communicating not using a VPN is rather new to us.

Currently there is a project to get rid of using Proxy, and instead of through a Load Balancer that can use rules to filter out traffic, which adds another layer of complexity.

I have a production with one Business Host - a Business Service which I need to scale automatically to consume ~80% of CPU time.
Business Service pulls data from a (non-FIFO) queue so that I can adjust pool size without any issues.

So far, I'm planning a different BS running every X seconds and sampling CPU with $system.Process.GetCPUTime() and scaling the pool size of the main BS up/down based on that metric.

Has anyone tried something similar? Any advice/code samples would be appreciated.

I'm trying to find a good way to control the Filename for X12 Acknowledgement files, but there doesn't seem to be a way to do that without custom coding. Here's what I figured out so far:

EnsLib.EDI.X12.Service.FileService allows you to set a Reply Target Config, which would likely be an X12 File Operation. The Service doesn’t have any settings related to the name of the Acknowledgement file though. That’s determined entirely by the Operation.

I want to deploy Iris Interoperability Production in multiple containers . The production has File Services that process files from EFS location. All the files being processed by multiple containers are in the same directory. The standard Adapter class does not have Check Complete option to lock a file so that other containers File Services looking in the same file path cannot process the same file.

I updated the Inbound File Adapter class to offer another Check Complete option LOCK that will lock the file until it is processed and archived.

My team is working on redesigning an Interoperability solution that currently runs on a HealthShare server that is part of a mirror. Most of the messages are delimited records processed using Complex Record Mapping. We were told to utilize cloud services available in AWS, use containers, autoscaling…

Credentials - Domain Account


I've a Service utilising the Adapter EnsLib.SQL.InboundAdapter, which uses a Credentials item set with the details of a local SQL account. This currently works, however, we're looking to use the credentials of an AD domain account.

The domain account is a member of an AD security group, which has the required permissions on the source SQL database. I've checked that access is possible with this account via SQL studio.
