Recently viewed a demo on the new Dynamic Objects in InterSystems (we are still running 2016.1); together with the upcoming IRIS data platform I started thinking about possibilities of building dynamic databases. That is, I can imagine some projects were it might be really nice to store dynamic objects and then run sql queries on them without ever defining the fields of the dynamic objects (i.e. not at storage, but only if you run your sql query).

Hi Community!

Consider I have InterSystems IRIS server in a cloud and want to introduce a DR server for it.

Are there any requirements for DR server for InterSystems IRIS if it is in a cloud?

Should it be the same subnet? One private cloud?

Can DR server be placed on another cloud, say Primary on Google Cloud and DR on Azure? Are there any caveats/concerns?

Hi guys!

As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).

1. Get it by as a property of an instance with "Object access":

ClassMethod GetPropertyForID(stId As %Integer) As %String

{

set obj=..%OpenId(stId)

return obj.StringData

}

2. Get it as a value of a column of the record with "SQL access":

Is there a way to get dynamic object from iterator?

set arr=[1,2,3]
set iter=arr.%GetIterator()

I pass iterator several frames down and I'd rather avoid passing both the array and iterator, but for debugging I need to access original object in a situation where only iterator is available.

Is there a way to do it?

Say I have an ObjectScript object called Book. It has 2 properties title and author. It extends JSON.%Adaptor, so I can call book.%JSONExport() and get this output:

{ "title": "For Whom the Bell Tolls", "author": "Hemmingway" }

In my web service I want to have a search function that returns an array of Books along with the total number of responses, like this:

Pyodbc supports calling stored procedure , but if the IRIS Stored Procedure ROWSPEC has a column with datatype specified as %Date or %Time, Pyodbc fails to fetch it and throws this error.

"

pyodbc.Error: (' 2201', '[ 2201] [Cache ODBC][State : 22018 ][Native Code 22005]\r\nERROR #388: Unknown error, code 22005 (22005) (SQLGetData)')

"

on printing the cursor execute description, pyodbc reads the column as <int>.

Hi, we suddenly noticed that one of the edge storage increased by 30% and it was due to ERROR globals which was throwing repeated error for 7 days and it consumed 35GB space. Is there a way to log the storage of edge production on daily basis and compare the increase in storage with previous day and if increase is 5% more than trigger an email to system admit to look why the storage increased suddenly.

We are using Native .NET API from IRISProviderCore21 package, inside .NET Core app, and having issue when trying to call function that takes instance of the class as parameter. The server is IRIS 2020.1.0.217.1

In a nutshell, the code looks like this:

// Create instance of the parameter class, proxy object

var paramObject = iris.ClassMethodObject("MyParameterClass", "%New") as IRISObject;

paramObject.Set("property", "value");

Hey everyone.

I have a process where I create a new %Stream.FileCharacter object, specify the filename (including it's path), write data to the stream, and then save. However for some reason, if the user account does not have write access to the directory, the %Save method is still returning true even though it was unable to actually write the file to the folder.

The location is a UNC path, and I'm wondering if this is tripping me up?

I have run into two annoyances when using VS Code for server-side editing of Objectscript and was wondering if anyone knows of any solutions or workarounds.

1. In .mac routine files, class names that aren't fully qualified (e.g. ##class(example) instead of ##class(Package.example)) fail to be understood, so the class will have a red squiggly underneath it and a problem that reads

"Class 'example' does not exist. InterSystems Language Server".
