#InterSystems IRIS

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.

Hi,

when I using ObjectScript Trigger Code , I want to get whether the fields has changed by using "{fieldName*C}" , actually, fieldName in "{fieldName*C}" is a real field name ,but in my code, fieldName is a variable as follows:

Hi developers!

As a follow-up to my previous post on the Node.js Native API, I created a quick poll because it may be interesting to see what technologies developers are using in their applications around the world with IRIS & Caché. I put a poll below, just check all boxes you have used or plan to use with InterSystems technology.

Thank you all for your cooperation!

How do I create recursive classmethod which stop all methods from running when condition are meet?

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');

Hi,

I'm often required to copy the database from production to test.

This is to 'refresh' the database on test.

To achieve this I copy all required IRIS.DAT files from production to test.

The nodes are mirrored on production.

The nodes are not mirrored on test.

Each of the database files IRIS.DAT has a mirror attribute.

Is there a way of checking if the mirror attribute is set for the database file? eg. an objectScript program

Sessions and specifically %session are paramount to our application to login users to the application (the Web Gateway user logs into the server and then users login to the application).

A mistake happened and records were assigned the wrong assigning authority name: PID3.4.

Everything else was correct. This resulted in duplicate records. Ex

Record 1: MRN1 has AA1 and clinical data

Record 2: MRN1 has AA2 and the same clinical data as Record 1 + more clinical data that is not in Record 1

I would like to remove Record 2 ensuring that there are no orphan records left.

Hi all.

I have a scenario where I am receiving NACKs and I'd like to adjust the error handing of the operation based on the content of the NACK.

For example, I could receive the following and want to move onto the next message:

MSH| ^~\&|||||20221025083135.489+0100||ACK ^A02^ACK|9271|D|2.5.1
MSA|AE|1664378390234
ERR|||207 ^Application internal error ^HL70357^^^^^^Cannot transfer patient, encounter is cancelled.|E

However, I could also receive the following and want to keep retrying:

Hello ALL!

I am having trouble fining a way to derive (a list, an array, a file doesnt matter yet how it returns) ALL of the targets of a routing rule.

For example lets say I have:

• a router of class: EnsLib.MsgRouter.RoutingEngine
• Business Rule: HappyRRN
• 1 rule set having 5 rules that each send to 1 DTL and 1 Operation (5 targets total)

My intent is to use some utlities we have created to disable all of the target operations of this router if the router errors out.

To do that I need the list of target operations.

Hi developers!

Those who code IRIS solutions in VSCode using Docker often use the convenient ObjectScript menu, which contains links to Management Portal, Class Reference, Unittest portal, Productions, etc.

While drilling down to a Dev Container to code Embedded Python there is no such option, at least within my settings:

So I don't know how to connect to it.

Thoughts?

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).

I have installed Iris in Docker container with the above version. I need to create an additional user to log in via ssh. I have created a user and put in both the irisuser and irisowner groups, and created a user in iris with permissions. But, when I run "iris session iris" I originally got an error about permissions: /usr/irissys/bin/irisdb: Permission denied.

I looked @ the /usr/irisys directory and the permissions was only (r-x------). I changed to (dr-xr-xr-x.)and now I get a different error:

Invalid ownership for ./irisdb

Any suggestions?
