#InterSystems IRIS

29

InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

I am trying to use EnsLib.SQL.Operation.GenericOperation for retrieving (multiple) rows. But I am looking for a way to handing a StreamContainer returned by the operation, in my business process such as receiving it in the Context object and packing it to a request to call another business operation.

Does anyone have sample code to do this?

Thanks.

Hi Friends,

In my production already we have business components (business service , process, operations) and all are working fine.

Now I have change the package structure of few classes and want to update the references in settings for Business components in Management portal.

As this class field is read only , Any other way to update the class reference, instead of creating new business component?

This is not an issue in ObjectScript, due to its typeless nature. But it's essential for external programming languages that care a bit more about types of variables.

And in any case, it's still reproducible in ObjectScript. I have table

CREATE TABLE some_table (
        id INTEGER NOT NULL, 
        x INTEGER, 
        y INTEGER, 
        z VARCHAR(50), 
        PRIMARY KEY (id)
)

And data

INSERT INTO some_table (id, x, y, z) VALUES (1, 1, 2, 'z1');
INSERT INTO some_table (id, x, y, z) VALUES (2, 2, 3, 'z2');
INSERT INTO some_table (id, x, y, z) VALUES (3, 3, 4, 'z3');
INSERT INTO some_table (id, x, y, z) VALUES (4, 4, 5, 'z4');

Hello guys,

i try to call a Operation within 3 foreach loops.

When i try to do this, i always get the following error:

I dont get any Errpr when i log my request message at this time i want to call a operation.

Everything works and i get no error. But when i try to call the operation i get this error.

Then i tried to call a operation in the first Level (not in a ForeachLoop) it works.

Trying to make some scripts to do some IRIS initialization during startup, I noticed that iris start and particularly stop takes too much time, and it starts to many processes in the background.

nostu is mostly useless for system initialization but could help in some scenarios, such as setup passwords, but it is still too slow

irisowner@4ea1bfb50b7f:~$ time iris start iris nostu
Starting IRIS
Using 'iris.cpf' configuration file

Starting Control Process
Global buffer setting requires attention.  Auto-selected 25% of total memory.

InterSystems IRIS is started in single user mode.
To log into InterSystems IRIS, type:
    iris session IRIS -B

real    0m0.513s
user    0m0.090s

For instance, I have no idea why it starts so many AUX processes, even during NOSTU. With a normal start with no extra volumes attached, just plain start, I see no reasons to have so many AUX processes as well.

For my Embedded Python ONLY demo package I need some user input.
Similar to ObjectScript

read "say somthing",reply

I use the Python equivalent

reply = input("say something")

And this works excellent without problems from Terminal or Doker console

BAD SURPRISE:
with WebTermnial ObjectSscript works fine, but embedded Python fails badly.

Monitoring Platforms

With System Alerting and Monitoring (SAM) being deprecated in the near future..

  • What is everyone's go-to for Monitoring IRIS?
  • What is readily available?
  • What is the cost surrounding it?

Just trying to get ideas floating around of what we might need to start looking at to satisfy IT leadership.

Thanks

Hi, I was wondering if anyone already dealt with this issue:
"System has been suspended for over X seconds, exceeding the maximum duration specified. Allowing system activity to resume. Any ongoing backup has presumably failed. Next InterSystems IRIS backup must be a full one"

our backup system "Commvault" is automatic, how do you tell it once you get this message that the next backup should be full?

thanks,

Eyal

This code snippet uses %ZEN.Auxiliary.jsonSQLProvider. The namespace and string of SQL can be edited for different situations. The class method "test" runs the code:


Class eduardlebedyuk.passQuestionParams
{
    classmethod test(pValue = 50) {
        s ns = $Namespace
        zn "samples"
        s tSQL = "SELECT ID, Name FROM Sample.Person WHERE Id > ?"
        s tPR = ##class(%ZEN.Auxiliary.jsonSQLProvider).%New()
        s tPR.sql = tSQL
        s tPR.%Format = "tw"
        s tPR.maxRows = 100
     
        s tParam = ##class(%ZEN.Auxiliary.parameter).%New()
        s tParam.value = pValue
        d tPR.parameters.SetAt(tParam,1)
      
        d tPR.%DrawJSON() 
        //d ##class(%ZEN.Auxiliary.jsonSQLProvider).%WriteJSONFromSQL(,,,,,tPR)  //same thing
        zn ns
    }
}

Hi,

I need to route a message synchronously to multiple targets using a routing rule.

In IRIS I built a general routing rule set, made up of a couple of rules. For one Rule in particular, and based on a common condition, I want to send the incoming message to 2 different targets. (no transformation is used)

I can select, in the single SEND action, multiple target names, or, I can create consecutive SEND actions, one after the other, each sending to their specific target.

Running predictive models natively in an InterSystems IRIS Business Process has of course always been the goal of our PMML support, but somehow never made it into the kit because there were a few dependencies and choices that needed addressing and answering. Anyhow, thanks to some pushing and code kindly provided by @Amir Samary (Thanks again Amir!), we finally got it wrapped in a GitHub repo for your enjoyment, review and suggestions.

Hi!

I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns.

Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Here is my code:

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:

A lot of developers like to work with Studio and have been looking into source code version control such as GIT or into enabling modern development workflows like CICD or DevOps processes.

This article describe an elementary solution to get you started in CICD and DevOps, even if you are not yet ready to move to Atelier or forth coming VS Code approach which enable client side source code version control.

Did anyone run into this error when stopping a Production from Ens.Director?

Ens.Director::StopProduction => ERROR <Ens>ErrProductionNotQuiescent: IRIS can not become quiescent

It happens sporadically when an automated unit test from a class that extends %UnitTest.TestProduction runs a test on a Business Process. I already increased the parameter MAXWAIT to 30 seconds, but the error still happens.
