I've been working for some days in the connectivity between NodeJS client applications and IRIS as server using web sockets.

You can get all the information in relation to the web socket connections using IRIS as a client or as a server from this URL: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...

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())

Monitoring IRIS through SAM (sam:1.0.0.115)

While I've used to make it work in the past, I'm not able any more to fix the already faced issue : "State: Unreachable"

Despite all the ip-addresses attempts (or hostname = host.docker.internal) and while "/api/monitor/metrics" is running well...

Could someone provide good practices to make it work cleanly ?

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

Ensemble 2017.2.

I am writing a DTL code action based on the solution described in the posting "How to avoid truncation in HL7 messages with very large fields (32K+)". Because the source value is in a repeating segment, and the specific repetition in which the value is located can vary, I would like to use a variable (specifically the k1 key) to specify the repetition to get. I have been unable to get it to work.

OBXgrp is the location in the path at which the repetition occurs. Hard-coding an index, as in the example below, works.

This is a series of programming challenges for beginners and experienced Caché programmers.

For an introduction : goto to article https://community.intersystems.com/post/advent-code-2016-day1-no-time-ta...

The input in today's challenge consists of an encrypted name, a dash, a sectorID, a dash and a checksum between brackets.
A name is real if the checksum is equal to the five most common letters in the encypted name.

New and Upcoming Embedded Git features

It's been a while since I've posted about Embedded Git on the Developer Community, and I'd like to provide an update on the massive amount of work we've done this year and where we're going next.

Context

If you're building solutions on IRIS and want to use Git, that's great! Just use VSCode with a local git repo and push your changes out to the server - it's that easy.

But what if:

in Management Portal on Freespace screen there are links to compact and truncate a database.

Can these tasks be done programmatically? I have looked through documentation and dont see anything but I hope I just missed it.

Thanks,

Does anyone have experience with CircleCI or really any automation tool using %UnitTest?

I have built my app and ran my unit test in a Docker container automated by CircleCI. However, after many of the tests failed I see:

How do you halt out of the IRIS session and return an exit code to the shell?

I have a script in my repo that I pass into IRIS after CircleCI does the code checkout

iris session IRIS < inFile

I am doing an implementation of a SAML 2.0 SingleSignOn protocol integration which requires a signed message with the signature element in the body of the SOAP message, not the header as is default SOAP security handling. Any suggestions for how to do this would be greatly appreciated. When it is passed in the header, it is not processed by our partner and we just get a "Signature Required" response.

I've created a scheduled task that dumps HL7 messages to flat files. It uses the OutputToLibraryStream() method of EnsLib.HL7.Message. I'd like to be able to run it on a mirror member host whether it's primary or backup.

When run against a database that's mounted read-only, it works fine. However, when I attempt to run it against a mirror backup database, I get the following error:

#5002: Cache error: <PROTECT>%LoadData+7^EnsLib.HL7.Message.1

Tracing that back to the source, I find:

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'm looking for information, suggestions, video (courses) on make a lot more use of the documatic system already built into Cache,

Probably talked of before within this forum, but after an hour or two of searching, can't find the articles that I mmay have seen before.

I want to do a lot more documenting of my installation, we use and actively comment classes and methods, but I want to take it further by actually documenting the "why" and high level "how" my system works. Documatic seems a good place to put that knowledge.

Hi all,

For special definition of the company, we need to define a PoolSize according to the environment that the "Ensemble" is working.

So the first try as been add the parameter into "System Default Setting"

However, this parameter is not available in "Setting default values" in Setting tab.

I've opened the code of my production and I've noted that this parameter is a attribute of the XML element of this item

"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.

Introduction

This paper describes how Ensemble behaves after a system crash or similar uncontrolled shutdown or failover. Ensemble is normally configured to start processing messages automatically when the operating system restarts or when the system has failed over to a cluster member or mirror member. No manual intervention is required. But, in order for your system to robustly handle system failure and restart, you must understand how Ensemble handles these conditions and develop your productions using the rules and guidelines in this document.
