Those of you who are following the FullStack competition here in the Developer Community will know that I submitted an entry named qewd-conduit.  I wanted to summarise why I think it's something worth you taking a bit of time to check out.

qewd-conduit uses the Node.js-based QEWD framework alongside IRIS to implement the back-end REST APIs for something known as the RealWorld Conduit application:

This is a very cool initiative as it provides a platform for lots of different people to implement technically different solutions for both the back- and

One of the most useful features in Studio is code snippets.

Here's how to add snippets to VSCode.

Here's a generalized instructions.

1. Go to File - Preferences - User Snippets and choose objectscript.

2. Add your snippet, here's an example:

"SQL Statement": {
    "prefix": ["sql"],
    "body": ["#dim rs As %SQL.ISelectResult",
            "set rs = ##class(%SQL.Statement).%ExecDirect(,\"SELECT * FROM\")",
            "while rs.%Next() {",
            "\twrite rs.ID, !",
            "}"]
}

In here:

  • prefix - what you need to type for the snippet to appear
  • body - snippet body

Even better,

We've just finished the second day of focus sessions - with a LOT of great content!  With parallel tracks, it's hard to keep up - but one advantage of a virtual conference is that you can watch anything you missed on-demand!

In yesterday's blog (Highlights of Day 1), I covered most of the special announcements such as InterSystems IRIS Adaptive Analytics and the FHIR Accelerator Service, so time to turn to a few broader strategic themes today.

Operations and System Management:   We're seeing more and more customers running in the cloud, as well as people that are employing modern deployment

Question Steve Riddle · Oct 9, 2020

Hi All,

I'm being asked if I can set up a AWS EC2 containerised version of IRIS and a separate AWS EC2 installation of Apache to serve IRIS web files.

Creating the Apache EC2 and containerised IRIS EC2 is the simple bit but getting them both to talk to each other does not seem quite so simple and I cannot find any documentation to describe how this can be achieved.

Has anyone else managed to achieve this?

I am trying to configure IRIS using python. The first task I wanted to do it change the journal directory. I cannot figure out the right way to work with the Config.Journal class with python. I can get the text to query the current setting.

returnValue = dbnative.classMethodValue("Config.Journal","GetList")
print(returnValue )

But I don't see a straightforward way to parse the $List returned by GetList() I was hoping there was an easier way.

How do I

1. Query configuration parameters?

2. Set configuration parameters?

Using python?

$LIST string format and %DynamicArray and %DynamicObject classes

IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values.  A data sequence that has been available for many years is the $LIST string.  Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation.  These two sequences involve very different tradeoffs.

$LIST String Format

$LIST format was invented some time ago when memory address spaces were small and when disk drives

Now that 1.0 has shipped and is featuring in various sessions at Virtual Summit 2020 it seems like a good time to offer some guidance on how to report problems.

InterSystems ObjectScript for VS Code consists of three collaborating VS Code extensions. For ease of installation and management there's a fourth entity, the InterSystems ObjectScript Extension Pack. It's a great way to get started with minimum clicks, and handy to have even if you have already installed the other extensions.

This modular architecture also means there are three different GitHub repositories where issues can be created.

Task: Identify your slowest SQL queries and tune them for better performance
Approach: Use InterSystems’ query profiling and analysis tools. Discuss how system configuration can affect performance
 

This session will show you how you identify the weakest link in your application SQL and introduce you to the fine art of tuning those queries. To do this we will take a look at InterSystems query profiling and analysis tools, as well as how system configuration can impact SQL performance.

Problem: Obscurity on how our SQL engine works

Question Jeffrey Drumm · Oct 23, 2020

I'm attempting to extract some very large messages from Interoperability/Ensemble, and I'm just not getting something right ...

The closest I've come to getting something useful is this:

ClassMethod GetHL7Msg(pId As %String) As %Stream.TmpCharacter [ SqlName = GetMsg, SqlProc ]
{
    Set tHl7 = ##class(EnsLib.HL7.Message).%OpenId(pId,,.tSC)
    Throw:$$$ISERR(tSC) ..GetErr(-400, "HL7 Message with ID "_pId_" Not Found.")
    Set tMsg = ##class(%Stream.TmpCharacter).%New()
    Set tSC = tHl7.OutputToLibraryStream(.tMsg)
    Do tHl7.%Close()
    Return tMsg
}

  1. I liked the transactional analytic DBMS and Advanced Analytics segmentation concept.
  2. The 1.0 version IRIS plug-in to VSCode is amazing. The partnership between community and InterSystems was very positive to it. However a low code option would do very well for IRIS in the near future.
  3. The Dynamic Gateways/Native API positions IRIS as the most advanced data platform for the main open languages in the market, but it is necessary use the public package managers from these languages, specially maven public repository.
  4. The API Manager is a good option but it is not available to the community

Prometheus is one of the monitoring systems adapted for collecting time series data.

Its installation and initial configuration are relatively easy. The system has a built-in graphic subsystem called PromDashfor visualizing data, but developers recommend using a free third-party product called Grafana. Prometheus can monitor a lot of things (hardware, containers, various DBMS's), but in this article, I would like to take a look at the monitoring of a Caché instance (to be exact, it will be an Ensemble instance, but the metrics will be from Caché).
