Detecting and managing failover

I have Ensemble/Healthshare running in a production environment which is setup with a mirror failover and an arbiter sitting between them.

In the event of a failover we have a number of connections that need stopping/monitoring and starting in a certain order.

Is there a programmatic way we can detect the failover and stop certain services and operations immediately and then start them up again in the required order, checking their connection state before starting the next connection.

Hi there,

I'm working on a project where I retrieve RawHL7 message(ORU R01 2.3.1) content from a database in a BPL. I've created a context object of type Enslib.HL7.Message, and I need to populate it with the contents from the RawHL7 message so that I can use this context object as source for my DTL transformation.

Does anyone have suggestions on the best approach to achieve this? I'm looking for guidance on how to efficiently transfer the data from the RawHL7 message to the context object.

Thanks in advance for your help!

Being interoperable is more and more important nowadays. InterSystems IRIS 2022.1 comes with a new messaging API to communicate with event streaming platforms like Kafka, AWS SQS/SNS, JMS and RabbitMQ.

This article shows how you can connect to Kafka and AWS SQS easily.
We start with a brief discussion of the basic concepts and terms of event streaming platforms.

Hi, guys,

I'm working on zen report to display an examination report for a client.

They stored order information in several tables. Examination findings and diagnosis were recorded in a html page and codes of the page was stored in another table. We need to put them together in one single report.

So far we can only read the html codes from that table which is a whole page since it start from label <html> and have <header>. We know that if we are using javascript we can display the page by assigning the codes to innerHtml property of an iframe object.

Code Golf: Diamonds
To start the year let's have a round of CodeGolf!

You know the drill. Shortest solution wins.

Print a size ascending range of Diamonds using the numbers 1 to 9, ranging from size 1 to size N, each diamond separated by a blank line.

A size 1 diamond should look like this, a single centered 1:

         1

With the size N=9 diamond looking like this:

Debugging Business Operations

Often we need to debug a Business Operation. Tracing and logging work but sometimes you want to work with a BO as with your local terminal session.

Here's how you can do that on any operating system.

Windows has a great tool for debugging Business Operations - Foreground mode. In that mode Windows launches a local terminal with operation job.

Using embedded Python while building your InterSystems-based solution can add very powerful and deep capabilities to your toolbox.

I'd like to share one sample use-case I encountered - enabling a CDC (Change Data Capture) for a mongoDB Collection - capturing those changes, digesting them through an Interoperability flow, and eventually updating an EMR via a REST API.

Now the Classes/Rutines/DeepSee files will be automatically exported to the working directory after saving or compiling and files will be automatically deleted .

Installation

To install isc-dev , you just need to download and import the file isc-dev.xml from last release.
Some ways to import isc-dev .xml file:

  • Go to Management Portal -> System Explorer -> Classes -> Import and select the XML file.
  • Drag the file over Studio.
  • Terminal command:
NS>do $system.OBJ.Load("yourpath/isc-dev.xml","ck")

NS>zpm
zpm: NS>install isc-dev

How to enable this feature:

  • After importing the class in the target namespace, run the following method to set up the working directory:
NS>do ##class(dev.code).workdir("/path/to/your/working/directory/src/")
  • Go to Management Portal -> System Administration -> Configuration -> Additional Settings -> Source Control.
  • Select the target namespace and set the dev.FileManExtension class as the main one and save it.
  • Try to create a new class in the studio and save/compile it
  • Enjoy!

Hello, I need to determine the best way to split a class containing multiple methods(about 20), into multiple classes in which each method is in its own class. I am wondering if there is another way other than manually creating the different classes, and copying each method into each class. Doing this in Intersystems Studio.

Hi,

I have tried to install the module git-source-control into my USER namespace, but get the following error.

ERROR! ObjectScript error: SQL error(s) have occurred during the running of the 'statsINFO()' method. Invoke the following method for additional details: set errID=##class(%SYS.PTools.Stats).getPToolsError(...) WHERE errRowID={2763|2764}>

I've writing a short classmethod that extracts an HL7 message from EnsLib.HL7.Message by ID and returns it as a stream. It's to be called as a stored procedure via ODBC (or ADO.NET) to fetch messages into an application.

I'm not using an SQL query in the classmethod itself, but it will be called as part of an SQL query via ODBC, but I can't figure out how to set a custom SQLCODE and error text from within the classmethod that propagates back to the external application. I thought %sqlcontext would be useful for this, but it doesn't appear to do anything. Here's the class:

Hello,

We have defined four BPL Business Processes. One gets occasionally errors when pool size is two. No errors happen with pool size one. The error happens on calling %Save() on a large objects with many references to other objects.

Error #5803: Failed to acquire exclusive lock on instance of 'classname'.

Error #5002: Cache error: <ROLLFAIL> %TRollBack+10^%occTransaction

The error happens on a particular large object.

Our FileService gets the same Errors #5803 and #5002 with class 'EnsLib.EDI.X12.Document'

Pattern Match with Cache

I'm trying to interpret a ObjectScript pattern and I am stumped on the first part. I understand everything else but not sure what 1.A means. I know A stands for Alpha characters just not sure what the 1. means

Hi,

Is there a way you can limit the amount of physical memory Cache uses?

During Cache backup it appears that all the available memory on the server is being used.

We are running Ensemble 2016.1 on Windows Server 2008 R2 with 32GB of RAM.

The database we are backing up is about 300GB.

Thanks,

Graham
