Routing Rule Usage -

Can we use Functions and Methods with multiple parameters and refer objects by reference as parameters inside Routing rule ?

How do we handle DB related workflows in Business Rules ?
How can we perform Response object based handling in Business Rules ?
Can we try by extending methods with Ens.Util.FunctionSet and pass in the Context object from the rule as a parameter for certain functions ?
Can we split the Business Operations into methods that can be used from the routing rules and create the message route request flow ?

Problem in Telnet

Hello folks,

We have recently upgraded the cache (5.x) to cache 2016. All are working perfectly. But i am struggling in Telnet.

Working Good,

when i connect to telnet it automatically gets the username(for example when we give the system ip addr(148.168.2.50), the ip address is taken as username) and directly goto the Password field in Telnet on old cache (5.x).

Now my problem is,

I can't get the same from my new upgrade instance 2016. When i connect to telnet it directly goes to username field but not to password field.

I need to create a routing rule where I've got to check for the value of "-" in field 5 of a repeating RQD segment, if the "-" is found in any of the RQD-5 I want to send it to a transform, if the rule doesn't find a "-" in any of the RQD-5 I want to send it to another transform.

Unfortunately we are running an older version of Ensemble and the foreach function is not available.

The other thing to add is the transforms are writing the output to a flat file so my business process is using the EnsLib.MsgRouter.RoutingEngine class.

Hello all,
I am creating a REST API with a spec-first approach. However, I am using the try-catch method to handle any exception if any occurs. But whenever any error related to syntax or something occurs, we get internal server error

{

"errors": [

{

"code": 6220,

"domain": "%ObjectErrors",

"error": "ERROR #6220: Internal Server Error",

"id": "InternalError"

}

],

"summary": "ERROR #6220: Internal Server Error"

}

Named Parameter In SQL with Python

Quick Tips: Total Productive Maintenance

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())

Security Scans

We are looking for a 3rd party application that can scan our IRIS based Cache Object Script code for vulnerabilities or coding weaknesses. There are many, many applications/vendors out there that do code scanning but none seem to support Cache Object Script or scanning the IRIS environment. If anyone is aware of a company/product that can scan our code / IRIS environment, I would love to hear about it.

Thanks in advance for the help.

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 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

Hello,

I had an issue when using the method Exists, I noticed that if you provide a directory for this method it returns 1.
This is really misleading, because sometimes the input could be a directory and the only way to predict this is to also test if the file is a directory.

I didn't tested using the Attributes method, but I supposed that this means could also be a solution for that issue.
But still, I expected the Exists method to return 1 for files and 0 for directories, since there's also method called DirectoryExists already.

Hey Developers!

Do you want to reap the benefits of the advances in the fields of artificial intelligence and machine learning? With InterSystems IRIS and the Machine Learning (ML) Toolkit it’s easier than ever.

Join InterSystems Sales Engineers, @Sergey Lukyanchikov and @Eduard Lebedyuk, for the Machine Learning Toolkit for InterSystems IRIS webinar on Tuesday, April 23rd at 11 a.m. EDT to find out how InterSystems IRIS can be used as both a standalone development platform and an orchestration tool for predictive modelling that helps stitch together Python and other external tools.

"SELECT %SYSTEM.SQL_TableExists('table name') "could work as expected under SQL shell,

but for "CALL %SYSTEM.SQL_TableExists('table name')" does not work (not any error reported, it just show nothing).

Is there any reason why CALL could not be applied to a stored procedure?

Thanks.

IRIS Drivers with maven

Once again I would like to know, if there are any plans to make Java libraries available through normal channels like public mvnrepository, like the whole world it's doing, where anyone can find any JDBC driver to any database in the world but InterSystems.

Currently there is only some useless garbage. There are just very empty files. What was the point of posting it there?

Creating and listing XData definitions

Hi InterSystems Community!

The ObjectScript language of InterSystems IRIS has the ability to extend classes using a very interesting feature called XData.

It is a section in your class that can be used to create custom definitions to be used within the class itself and also externally.

To create one or more XData definitions for your class is very easy, see the example:

Is anyone using Atelier with 3 environments (instances with multiple namespaces) (DEV, TEST, PROD) using GitHub as the source control.

I would be interested in how its all setup. So for example;

Would you have three branches for the code or 3 repo's.

Would you have three projects in Atelier to communicate with the environments and GitHub?

I have 3 existing environments that I wish to put under source control and also provide the ability to promote code between the environments in a controlled manner.
