#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

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?

Hi Friends,

I have a requirement to convert pdf from URL to Base64 format. I have created one utility method and used in the DTL.

Working fine for small pdf files , we got one pdf with size 4MB , this method is failing (creating corrupted base64 content).

Could you please suggest me the way to convert big pdfs?

Hi,

I need to do a DELETE and then do some INSERT transactions on a linked table and don't want the DELETE and need to be able to ROLLBACK the DELETE if any of the INSERT transactions fail.
I have tried Object Script transaction processing (TSTART, TCOMMIT and TROLLBACK) and the SQL transaction processing (START TRANSACTION, COMMIT and ROLLBACK), but neither work.
Could I be doing something wrong in the way I am implementing these, or do does transaction processing simply not work for linked table?

Thanks for any advices, in advance.

Neil

Folks!

Could you please share any best practices on how to debug Embedded Python code?
