Hi,

We are developing a .NET6 application using Iris database. We would like to use ORM for easier code maintenance.

I saw a doc about Entity Framework: https://docs.intersystems.com/iris20231/csp/docbook/DocBook.UI.Page.cls?KEY=BNET_eframe, but even it's newest Iris version, the Entity Framework is very old .NET Framework (2013) and not supported by Microsoft anymore. Are there any plans to support Entity Framework Core?

The new $system.external interface (aka "InterSystems External Servers") is used to call/integrate with external language code/libraries, it replace the old gateways (for example Java gateway) that required the import of proxy objects.

Note that the documentation for the old gateways has been removed from IRIS, so only the new $system.external interface is somewhat (i.e. insufficiently) documented.

Regarding the migration from old gateway to new $system.external interface the documentation says:

I'm at a loss with configuring the IRIS ODBC driver (v02.10) on my Amazon Linux machine, connecting to a REMOTE IRIS backend. It should be simplified by not requiring a DSN (the app uses a DSN-less connection and generates the connection string). I have

hi!

I am going to develop a ASP .NET Core Application. In that Hos can use IRIS Entity Framework. I searched but I couldn’t find IRIS Entity Framework for .Net Core . Please kindly help me to overcome this issue.

thank you in advance

I have updated some legacy VB/ASP.NET code and changed the references of InterSystems.Data.CacheClient to InterSystems.Data.IRISClient. I am struggling with the code as I am not a .NET expert and there is little or no documentation.

Our ERP solution runs on different sql databases (such as ms sql and posgre). We are using the same code for all plattforms, doing database-specific changes in the db driver for each type of database.

There is one function in our program, where the user can store long text to discribe something, which is used in print and web. This text is treated/stored as html and can include pictures. The pictures in the html are stored base64 coded inside the html and the html is stored as text in a column. In other database systems, this is treated as TEXT or BLOB, and workings just fine.

Hi

I am upgrading our application from dotNet Framework to dotNet Core.

Prior to the upgrade I was able to connect to both my Cache & IRIS instances using the IRIS ADO.NET driver.

However, in dotNet Core, whilst I can connect to IRIS, I get the following error connecting to Cache.

InterSystems IRIS Provider is not compatible with Cache xDBC server

I am using the IRIS driver from the Windows (x86-64) 2022.1 distribution (the one in dev\dotnet\bin\net5.0).

The cache version is Cache for Windows (x86-64) 2018.1.2

Thanks

Integrating Cache with .net may be difficult, as we need to know both technologies and tools involved. Let’s follow the simplest possible example and see the pitfalls lurking on our way.

1. Creating .Net Assembly

.Net assembly is unit that contains compiled code and other resources.

Let’s create the simplest .Net assembly that will contain the code we want to execute.

We will use assembly of type Class Library, as we will use classes and their methods contained within. This type of assembly has .dll extension.

Introduction

InterSystems IRIS 2020.1 includes PEX (Production EXtension Framework) to facilitate the development of IRIS Interoperability productions with components written in Java or .NET.

Thanks to PEX, an integration developer with knowledge of Java or .NET can benefit from the power, scalability, and robustness of the InterSystems IRIS Interoperability framework and be productive in no time.

Hi, I tried the following exercise from the IRIS documentation. I updated the username, password and IP address, but receiving this error;

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. --->

I can use the same credentials and IP address to connect ok via VSCode to my local IRIS...

Any pointers much appreciated.

Hello,

I have an error connecting the InterSystems cache with the odbc driver with the ODBC-2017.2.2.865.0-lnxrhx64.tar version using the ubuntu versions 20.04 and version 18.04 (which works with the .Net Core 3.1 version) with the Net 6.

Error:

I'm new to cache, come from an oracle and sql server background. In oracle and sql server I could write basically a stored procedure like script and pass it in as text to the command to execute.

Example:

Below would be the _sqltext

DECLARE @Id INT;

select id into @Id from something;

if @Id = 9

BEGIN

do something

END

The _sqltext would work in sql server, what would be the equivalent for cache for it work?

I get a generic error when I try it with cache
