Pre-requisite - Basic knowledge of ENSEMBLE and ObjectScript

My both previous sessions were related to OBJECTSCRIPT.
This time, we are going to add a flavour Ensemble/Healthshare,
to be informative and fast.

In this session we are going to discuss about - 
"Informative and Fast WEB API VIA ObjectScript and Ensemble/HealthShare"

Web API can be REST or SOAP. We will taking example of SOAP in this session.
However, whatever I demonstrate today, will also be applicable for REST.

In today's Session, we will creating 2 versions of same API and will Compare there performance using tool called SOAP U

Cogs Library

Over the next few months I will be releasing a number of open source libraries and tools to the Caché community.

Most of the code has evolved from previous production grade solutions over the years and I am collating it together under a single overarching library package that I am calling Cogs.

Hi developers!

Every day coding with IRIS and docker I call the following 3 commands in VSCode terminal. Always the same for any projects:

docker-compose build   ; to build the container

docker-compose up -d   ; to run the IRIS in container

docker-compose exec iris iris session iris ; to open the IRIS terminal

Is there any way to map the key sequence which will type me the rest? 

e.g.

irisb for docker-compose build,

irisup for docker-compose up -d,

irist for docker-compose exec iris iris session iris

I know and use keyboard sequences for mac, but it doesn't work in VS

In many projects I was faced with storing hierarchical data (tree) in classes.
By tree, I mean such data, where each node has a parent node — an object of the same class.
Many examples of such data can be given. For example, a catalog in the online store. Suppose that this online store sells books, in this case, the category tree might look like this:

The number in front of the name is the category ID.
For storage, you can create classes:

The MyApp.Category class  is used to store the category tree and contains the property “Parent” - reference to the same class.

But it’s not convenient to work wit

In this article we are going to compare $Increment and $Sequence functions.

First of all, a note for readers who have never heard of $Increment. $Increment is a Caché ObjectScript function which performs an atomic operation to increment its argument by 1 and return the resulting value. You can only pass a global or local variable node as a parameter to $Increment, not an arbitrary expression. $Increment is heavily used when assigning sequential IDs. In such cases parameter of $Increment is usually a global node. $Increment guarantees that each process using it gets a unique ID.

Hi Developers!

Happy to share with you the release notes of InterSystems Developers community site in August 2019. What's new?

• Direct messages between registered members;
• Accounts merging;
• Better navigation for serial posts;
• Spanish DC enhancements: translated tags, analytics.

See the details below.

Let's have a round of CodeGolf!

As usual the goal is to write the shortest solution for a specified problem.

Today we have one of the classics: FizzBuzz.

Write a program that prints the numbers from 1 to 100.

But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”.

For numbers which are multiples of both three and five print “FizzBuzz”

​​​​​​We have Full time or Part Time Cache\ENSEMBLE\IRIS programmer positions available with our UK and US/North American teams.

For details on what we do and our products please see our web site intsoftsol.com  

Interested persons should email reply to admin@intsoftsol.com

Leveraging an Open Analytics Platform

Hi all,

I'm looking to set up monitoring for several interfaces. I understand that I can set an Inactivity Timeout. However, obviously there are messages coming through more frequently during certain hours than other hours. 

Is there a way to set an Inactivity Timeout for each hour of the day instead of one value that is used all day long? 

Best,

Erin

I've setup ODBC connection so I can access Cache data within SQL Server.

I want to be able to write SQL queries for internal monitoring purposes, similar to what's possible with SQL Server.  Specifically I want to be able to check mirroring status (i.e. check which is the current primary mirror member), check the status of any Ensemble productions (started/stopped), check the status of business hosts etc.  I want to do all of this from SQL Server to go with our other system monitoring solutions.

Does anybody know if this is possible, and if so the names of tables/namespaces which might store the

I discovered the upload file button does not appear to work properly but you can still attach files under 'change additional settings'.  Are there plans to fix this?

Hello Everyone

I'm trying to open an XML that I get inside a GZIP file.
However, I can only open the contents when I save the file to a folder.
I would like to know if there is a way to get the contents of XML without saving the GZIP in a folder.

The code below is functional, however, you are saving GZIP before you can get the contents of the XML.

SET tGZIP = $System.Encryption.Base64Decode("############")
SET tFile= ##class(%File).%New("####")
SET tSC = tFile.Open("WSN")
SET tSC = tFile.Write(tGZIP)
DO tFile.%Save()
DO tFile.Close()
SET tSC = tFile.Open("RUK:::/GZIP=1:/NOXY=1")
WHILE 'tFi

Has anyone had any success receiving a DICOM TCP in, and then using a process to write to a file while responding to the sender correctly? I'm pulling my hair out, and would love to know where I'm going wrong.

Hello community,

I need to know if there is any method which can me say specified imported files or namespaces in Cache.

To better specification of my problem, I've got two installer manifests. Firts one did some resource changing and import some files and classes, second one must be started after the first one, because it's only his update, which creates some nemaspaces. So i need to check if the first manifest ran succesful and I can start the second one.

Is it good way trying to do this by some method or are there some other, better ways maybe by ccontrol, I don't know?

Thanks so much f

Hello,

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:

(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()

License Server summary view of active key.

     Distributed license use:

Current License Units Used =        1

Maximum License Units Used =        1

License Units   Authorized =      200

     Local license use:

Current Connections =      1  Maximum Connections =      1

Current Users       =      1  Maximum Users       =      2

(From Linux OS Terminal)

[jhipp@test-sbox ~]# csession TEST "##class(%SYSTEM.Lic

Good morning,

I'm trying to understand $ZF function, but only documentation isn't enought in this way. So my question is is there any possibility to get enviroment variable by this function into ensemble?

I've tried this as example from ducumentation, but there is an error and  I don't know why...

Thanks for your solutions.

Hello Community,

How do i disable an operation explicitly based on a value in a variable?

I set the ReplyCodeAction to E=D.

In the Operation Code i am throwing an explicit ERROR

THROW ##class(%Exception.General).%New("Shutting Down Operation",999,,"My own special exception")

But my operation still remains up.

Any suggestions please will be appreciated.

Thanks,

Jimmy Christian.

I'm not saying that this is in anyway "best practices," but I'm in a peculiar situation where I need to restrict users from starting a "retired" Ensemble Production in a namespace that's been renamed. It's still an "Ensemble-activated" namespace; we need to keep it available for Ensemble Message Viewer access ... fortunately, only for a little while.

It's a bit of a hack ...

Open the Production class in Studio and add the following classmethod:

ClassMethod OnStart() As %Status
{
    Return $system.Status.Error(5001,"THIS PRODUCTION IS DISABLED.")
}

A Production won't start if its OnStar
