Hi all,

Do you know if there is a way to create a Lock that is related to an existing transaction, in the sense that if transaction is finished (commit or rollback) Lock is removed. I ask this because in the following example Lock is there until process is killed.

Example :

TSTART

Lock +^MyLock

TROLLBACK

I know, that, Caché itself is locking internally a table register when doing an OpenId with exclusive flag during the transaction life. For example :

TSTART

I keep seeing <INVALID OREF>zMyproperty<

I have created a class that extends file operation, but can't find the object that has the value for the file path. Is that object in pRequest or is there an another object I should be used to see that value?

Hi, Community!

We have a new release here!

What has been introduced:

1. Better notifications

With this release I hope you will turn on back the email notifications because every new notification today in the beginning of itself will tell first, why did you get it describing the exact reason you got this particular notification. And if you don't want this type of notification to be delivered anymore click unsubscribe link in the notification and it will lead to the settings of this very type to alter.

(Possibly?) little-known fact: It's possible to use $ListBuild on the left hand side of the equals sign in a set command to extract multiple list values at once:

For example:

Hi Developers,

Python has a large and powerful ecosystem that contains thousands of libraries and packages available, especially in data science.

Therefore, I wanted to have a first try in using a recent feature of IRIS called Embedded Python, to simply import a python library called datetime, generate data with a timestamp component and persist it in InterSystems IRIS for Health Data Platform. The same will work on IRIS Data Platform as well.

I have just started to experiment with Using IRIS in Docker.

My first objective was to be able to enable global persistence within a Docker container. Using the following command I have managed to achieve this:

docker run --detach --publish 52773:52773 --volume /data/dur:/dur --env ISC_DATA_DIRECTORY=/dur/iconfig --name iris21 store/intersystems/iris-community:2020.1.0.199.0

Within this container, I have created a simple global:

for i=1:1:10 set ^tmp(i)=""

Hi developers!

Every day coding with IRIS and docker I call the following 3 commands in VSCode terminal. Always the same for any projects:

docker-compose build   ; to build the container

docker-compose up -d   ; to run the IRIS in container

docker-compose exec iris iris session iris ; to open the IRIS terminal

Is there any way to map the key sequence which will type me the rest?

e.g.

... but let’s first take a look at two relatively small topics, and namely:

Creation of a multi-page REST application

We only have one page for now. How about adding one more? Said - done.

Currently, namespace Alpha is configured to use database AlphaDB as its global database. How would we go about having namespace Alpha configured to use database AlphaDB for its global database except where global ^Customers(CustomerId) has a CustomerId greater than 10M, which we would like to have it redirected to database BetaDB.

In other words, ^|"AlphaDB"|Customers contains all customers between 1 and 10,000,000; and ^|"BetaDB"|Customers contains all customers greater than 10,000,000. Any help would be appreciated.

Named parameters can be achieved with SQLAlchemy :

from sqlalchemy import create_engine, text,types,engine

_engine = create_engine('iris+emb:///')

with _engine.connect() as conn:
    rs = conn.execute(text("select :some_private_name"), {"some_private_name": 1})
    print(rs.all())

or with native api

from sqlalchemy import create_engine, text,types,engine

# set URL for SQLAlchemy
url = engine.url.URL.create('iris', username='SuperUser', password='SYS', host='localhost', port=33782, database='FHIRSERVER')

_engine = create_engine(url)

with _engine.connect() as conn:
    rs = conn.execute(text("select :some_private_name"), {"some_private_name": 1})
    print(rs.all())

Talking with a friend of mine, Machine Learning specialist @Renato Banzai , he brought one of the biggest challenges faced by companies nowadays: deploying ML/AI in live environments.

hi all,

I am looking to make a JDBC connection to my Intersystems Cache using the JDBC driver 2.0.0.

I see the connection format is as "

   jdbc:Cache://<host>:<port>/<namespace>

"

What I really want to do is filter additionally by a certain database, i.e. connect my consuming application to a database under the namespace.

how can I do that? what will be the format
