Good evening Intersystems Community,

I want to participate in the Advent of Code 2020 and followed the installation instructions in "The Advent of Code 2020 contest ObjectScript template" (https://openexchange.intersystems.com/package/aoc2020-objectscript-template).

Unforunately I get "Error: Invalid Community Edition license, may have exceeded core limit." at the step "docker-compose build".

Hi all,

I am trying to delete an item from a production through a routine that installs and disables items.

To add any item, I have no problems, even to enable and disable some particular items.

The problem arises when I try to eliminate the production item, because when it does, the production become unstable and only works again when this item is added again in the collection (or the item is deleted manually in the production.cls)

This is my code attempt:

We will receive an ORM message in Business Service in Iris. From that ORM, an ADT^A31 message will be generated and sent out to the EMR before the ORM message is sent out. The ORM message has to wait until Iris receives an acknowledgement from the EMR indicating the ADT message was received. Then, the ORM message will be sent to the EMR. What do I need to set up to hold the ORM message until the acknowledgement is received?

(I wasn't able to find this in the docs or the Community, so feel free to point me to a reference that I missed)

How can I determine the effective User and Group that will be used when an InterSystems IRIS process is doing file I/O on the file system for UNIX? Bonus points if you can tell me how to do it from within InterSystems IRIS as well as from the host OS.

Thanks!

Maximum Global Size ?

Dear people,

I (really) spent hours on finding the maximum size a Global is allowed to be (for Windows, if that matters). All I seem to run into are database sizes (derived from a max number of blocks and block size), but I refuse to believe that is correct because too small to be realistic. surprise

Read data from Excel

Hello,

I work as a contractor for the Department of Veterans Affairs. I want to read data from an Excel workbook. I searched posts here and saw Apache POI suggested. I believe Apache POI is not approved for use within VA. I also believe we should be able to run SQL query against Excel. Has anybody done such a thing or are there other ways to read data from Excel workbooks?

Thanks

Iris vs Java

Hello. I'm having problems migrating a java application that is running with cache 2018 to Iris
The application uses json generated by the cache to receive it as a string in java.

in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?

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

Hi,
For a REST application, when a user connects, I have to write a message in an application log.
The login is processed by the /login routine by default.

How can I add a process to the login process?
Is there a callback ?
Should I create a login method in my class that extends %CSP.REST ?
I'm not sure and can't find information in the documentation ?

I try this (not working) :

<Routes>

<Route Url="/lists" Method="GET" Call="GetLists" />

<Route Url="/me" Method="GET" Call="GetUserInformations" />

IRISPIP Cryptodome C++ Error

Hello,

I need AES ECB with PKSC7 padding for an interface.
Unfortunately, the %SYSTEM.Encryption.AESEncode cannot do this.

Therefore I wanted to include the following python lib.
PyCrptydome -> https://pycryptodome.readthedocs.io/en/latest/index.html

We need to install the package offline on the system. So I downloaded it and put it in the MGR/Python/ directory.

However, when I try to install it, I get the following error message:

Hi everyone,

Lately, I've been spending a lot of time with Visual Studio Code (VSC), and I've been wondering if there's a terminal or a panel within VSC that acts like the Intersystems Studio Output panel, which serves both as an input and output window and allows the execution of ObjectScript commands.

Could anyone help? Thanks :)

Hello!

I am taking the 'Creating an InterSystems Class Definition' course, and the Exercices asks to open a Terminal from the Management Portal to create and interact with a new object. I didn't found how to acces tot the Terminal from the Management Portal, and the documentation I have seen doesn't help me... sad

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');
