Presenter: Mark Bolinsky
Task: Provide failover for distributed systems without using a VIP
Approach: Demonstrate using InterSystems’ database mirroring with external traffic managers such as F5 LTM/GTM

With distributed environments and even public cloud environments, the use of a VIP sometimes is not desirable or even possible given network topology or deployment. The session will demonstrate integrating database mirroring with external traffic managers such F5 LTM/GTM using API based triggers in InterSystems products to interface with the F5 appliances. This not only presents automated redirection for the local mirror members, but also provided automated client redirection to asynchronous DR mirror members.

I had a question about using ZSTART, ZSTOP, and ZMIRROR.

• If we use them and it is not correct, does it mess up with any of the existing functionality?
• So, if I create a ZSTART with a simple command of starting the %JDBC Server will that mess up anything existing in the Startup sequence?
• Is ZSTART, ZSTOP, and ZMIRROR just an extension of the existing functionality, or does it alter how the built in functionality runs?
• Should we tread lightly in the use of them?

I think there have been articles published here before but I'm struggling to find them:

I'd like to be able to create my own customised version of the official IRIS Community Edition Container, eg with Node.js and a number of modules pre-installed. So, for example, can I create my own Dockerfile that begins with something like:

FROM containers.intersystems.com/intersystems/iris-community-arm64:2023.2.0.227.0

and then I can add my own stuff to it?

... or is there another recommended approach?

Any info appreciated

Hi all,

I'm wondering if exists any command or method to replace a text using parameters.

In C# I use the Format property

Following "Adding Custom HL7 FHIR packages to the HL7 FHIR server" at https://learning.intersystems.com/course/view.php?id=1721 I'm able to create an FHIR extension of type string as well as a search parameter.

However, I need to create an extension as well as a search parameter of type Reference. And this is not working.

Did anyone successfully add an extension and search parameter of type Reference?

We have code with the line

HI,

I have made a query with class definitions and all their properties and put them in a view.

All is good besides Parameters is showing junk characters. Is there a way to do it cleanly besides getting into the code??

SELECT
CC.ID As CompiledClass,
CC.SqlSchemaName,
CC.SqlTableName,
CP.Name As PropertyName,
CP.SqlFieldName,
CP.Type,
PD.Parameters

FROM %Dictionary.CompiledProperty CP
JOIN %Dictionary.CompiledClass CC
ON CP.Parent = CC.ID

Hi,

we are moving an existing ZEN-Application to a new version of Caché (2017.2.2). It is a rather old application and we need to do some modifications due to the thightend security of ZEN in this and prior release (we came from 2013.1). One of the changes required is to alter a table Name of a ZEN-Table on the server-side. Anyway this gives us a problem, since we receive an error

ERROR #5001: Client modification of protected property ( tableName) disallowed for security reasons.
SOURCELEMENT: %ZEN.Component.tablePane (tpSimilarity)

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.

Hi everyone,

It could be great if some of you have had experience in hl7 v2 messages. The question is about FHIR to hl7 v2.5 conversion. I have to translate a binary resource, encoded in base64 into an orl_o22 message. Do you have advices? Which field could be used for that datatype?
I have found some implementation using nte segment but it is limited in characters.

Thank you

Hey community!

It's time to elevate your unit tests to the next level with iris-TripleSlash new solo feature!

We are bring to the game Setup and Tear down events!

Just add description on class, with special tags like:

• beforeAll
• beforeOne
• afterAll
• afterOne

The tripleSlash will turn it to:

Hi Guys,

my understanding that Arrow can't be used in left or right joins as the example below, so is there an alternative ?

SELECT Sample.Employee.Name, Sample.Company.Name AS CompName
FROM Sample.Employee LEFT OUTER JOIN Sample.Company
ON Sample.Employee.Company->Name = Sample.Company.Name

Thanks
