In this article, we will run an InterSystems IRIS cluster using docker and Merge CPF files - a new feature allowing you to configure servers with ease.

On UNIX® and Linux, you can modify the default iris.cpf using a declarative CPF merge file. A merge file is a partial CPF that sets the desired values for any number of parameters upon instance startup. The CPF merge operation works only once for each instance.

Our cluster architecture is very simple, it would consist of one Node1 (master node) and two Data Nodes (check all available roles). Unfortunately, docker-compose cannot deploy to several servers (although it can deploy to remote hosts), so this is useful for local development of sharding-aware data models, tests, and such. For a productive InterSystems IRIS Cluster deployment, you should use either ICM or IKO.

I have done Python - Cache binding setup following the guide from http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=.... I have also run test.py from sample3 folder and it able to run and complete successfully.

However, when I try to run the same test.py code via $zf, it gives error with exit code 1.

I've tried running help("intersys.pythonbind3") via $zf and also running from Cache terminal as follows:

Hello Community,

I want to secure a SOAP Webservice (an EnsLib.SOAP.Service one, if that matters) adding a SSL/Username Policy to it. As im not sure how detailed my request here should get, ill try giving a detailed as-is description of my setup, what I've tried, how I tried to test the connection and what problems including some logs I ran into.

As a small foreword: I'm pretty new to the whole security aspect of intersystems and soap itself.

IRIS Document Database (DocDB)

InterSystems IRIS Document Database (DocDB) offers a flexible and dynamic approach to managing database data. DocDB embraces the power of JSON (JavaScript Object Notation), providing a schema-less environment for storing and retrieving data.

It is a powerful tool, enables developers to bypass a ton of boiler plate code in interaction with existing applications, serialization, pagination and integration. the seamless flow of DocDB with Interoperability Rest services and operations, gives a big leap in API production and management.

for full DocDB documentation Here. in the context of this article i will showcase a use case in which DocDB will make a perfect fit.

In this article, we will establish an encrypted JDBC connection between Tableau Desktop and InterSystems IRIS database using a JDBC driver.
While documentation on configuring TLS with Java clients covers all possible topics on establishing an encrypted JDBC connection, configuring it with Tableau might be a little bit tricky, so I decided to write it down.

Hello everyone,

I have a doubt, its possible to use interface like C# using COS?

Remember, interface is different from Abstract Class, because a abstract class can implement code in the method, so I don't want this, I want only define the methods from Class, not allowing implement code.

This formation, accessible on my GitHub, will cover, in half a hour, how to read and write in csv and txt files, insert and get inside the IRIS database and a distant database using Postgres or how to use a FLASK API, all of that using the Interoperability framework using ONLY Python following the PEP8 convention.

Under the previous python binding method (Cache) it was possible to pass in parameters, execute a class query, and fetch the result sets. I have been unable to find a way to do this via PYODBC or the Native API (perhaps I am just missing something).

My work around is to create a SQLquery string and execute it through a cursor. I would much prefer to simply execute the debugged and more secure class queries that already exist and and have been precompiled.

Any pointers would be greatly appreciated

Thanks,

Sinon

[Background]

InterSystems IRIS family has a nice utility ^SystemPerformance (as known as ^pButtons in Caché and Ensemble) which outputs the database performance information into a readable HTML file. When you run ^SystemPerformance on IRIS for Windows, a HTML file is created where both our own performance log mgstat and Windows performance log are included.

Hi,

I would like some help/ information regarding queued messages.

I have 1040 messages that are queued, but I only want to process the first 28 of them. Is there a way that I can do that?

If I abort them, would all of them go away?

Would appreciate if you can advice me on this

Regards,

Eric

Hi guys,

Open question for all of you...

We are getting some warnings in our code of a class definition when switching namespaces in the code, because the classes we use in different namespace wouldn't exist in each other's... an example:

ClassMethod DoSomething() {
     set oldNS=$zutil(5)
     znspace "SECONDNS"
     set ok=##class(MyPackage.MyClass).MyMethod()
     znspace oldNS
}

In that example, the vscode "Intersystems Language Server" extension would tag "MyPackage.MyClass" as a problem because that class only exists in the second namespace.

Extend XData UrlMap

Hi all,

I'm wondering if is possible to extend the UrlMap.

I want to create a base class and one method will be in all extended classes, so I've tried to create the map route in parent class, and the specific methods in extended class. But it doesn't work.

I've create the method in parent class and I've wrote the map in extended class. It works, but I want to put it in base class to prevent forget this call.

Note: The base class extend to %CSP.RES

Best regards,

Francisco Lopez

Hi,

If I test the Native api for Node.js from the documentation, I noticed (if I'm correct) all methods and calls are synchronous. By default due to the nature of Node.js, there is only one thread of execution and normally all JavaScript methods and all calls should be asynchronous and use either a callback function (the "old way") or promises or the async/await contruct to return their result, e.g.:

I have a table, with autoincremented id

CREATE TABLE users (
    id SERIAL NOT NULL,
    name VARCHAR(30) NOT NULL,
    PRIMARY KEY (id)
)

I can add a new item there with an explicit id 

INSERT INTO users (id, name) VALUES (2, 'fred')

And while my id is autoincremented, I can omit it

INSERT INTO users (name) VALUES ('ed')

So, this time, I don't know the id, and I want to somehow get it.

I could do it with LAST_IDENTITY() function, but it just uses %RowID, and have no relation to the primary id

I have a permanent job opportunity which would ideally suit someone from Europe who want's to experience the UK (initially London), the requirements are fluent in Cache Objects, SQL, XML, Integration, English Language and be self motivated with a desire to experience London.

I am NOT a recruitment agency and will offer personal help in relocation and culture differencies to handle moving countries.

I do not offer a relocation package but will offer advice, guidance and help in relocation.

Hi community,

I would like to ask how to correctly enforce SSL on all "developer traffic" -- that is Management portal and Studio connections -- on a Caché instance.

Given large developer permissions, I would like to eliminate all plaintext credentials on the wire.

Currently, we compile our own httpd with SSL support for Management portal, but this breaks Add-Ins for us, in particular the SOAP wizard. So I guess this is not the "canonical way".

Thanks for any suggestions

Jiri
