⏯ How to Create and Submit an Application for InterSystems IRIS Online Programming Contest 2020

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.

In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

I'm building a container from store/intersystems/iris-community:2019.4.0.383.0 .

I need to add my folder to the LD_LIBRARY_PATH  so that my custom shared library would load at runtime.

How can I do that?

Here's what I tried:

ARG IMAGE=store/intersystems/iris-community:2019.4.0.383.0
FROM ${IMAGE}

USER root

ENV MYDIR /usr/mydir

ENV LD_LIBRARY_PATH $MYDIR:$LD_LIBRARY_PATH

RUN mkdir "$MYDIR"; \
	chown -hR $ISC_PACKAGE_IRISUSER:$ISC_PACKAGE_IRISGROUP $MYDIR; \
	chmod -R 777 $MYDIR; \
	echo "LD_LIBRARY_PATH=\"$MYDIR\"" >> /etc/environment; \
	echo "$MYDIR" >>

Hello,

The application I am working on for Iris Contest needs to send an email. Is anybody aware of a configuration for SMTP server, port, credentials that I can use for the contest or any demo application?

Thanks,

There are several options how to deliver user interface(UI) for DeepSee BI solutions. The most common approaches are:

• use native DeepSee Dashboards, get web UI in Zen and deliver it in your web apps.
• use DeepSee REST API, get and build your own UI widgets and dashboards.

The 1st approach is good because of the possibility to build BI dashboards without coding relatively fast, but you are limited with preset widgets library which is expandable but with a lot of development efforts.

The 2nd provides you the way to use any comprehensive js framework (D3, Highcharts, etc) to visualize your DeepSee data, but you need to code widgets and dashboards on your own.

Today I want to tell you about yet another approach which combines both listed above and provides Angular based web UI for DeepSee Dashboards -  DeepSee Web library.

⏯ InterSystems IRIS Cloud Roadmap

Hi all. Yesterday I tried to connect Apache Spark, Apache Zeppelin, and InterSystems IRIS. During the process, I experienced troubles connecting it all together and I did not find a useful guide. So, I decided to write my own.

Introduction

What is Apache Spark and Apache Zeppelin and find out how it works together.Apache Spark is an open-source cluster-computing framework.It provides an interface for programming entire clusters with implicit data parallelism and fault tolerance.So, it is very useful when you need to work with Big Data.

Hi ,

I have a code written in cache  sql and trying to understand it, below is the code , can anyone help me understand what does that mean 

ex - !! dosage_unit !!

SELECT (CASE WHEN (order_description IS NULL OR (order_description='')) THEN '' ELSE (order_description) END) !! (CASE WHEN (dosage IS NULL OR dosage_unit IS NULL OR (dosage='') OR (dosage_unit='')) THEN '' ELSE (', ' !! dosage !! ' ' !! dosage_unit !!

Thank You in advance.

Good Day;

looking at disabling Telnet - on Windows - Cache 2012,2017. The security scans don't need it on network.

But still leave users able to use `Terminal - direct - on the box should be fine.

am posting here for quick refs (as this is a common security vulnerability out there).

Hi everyone,

I have a javascript function in *.js file. This function has to access to variable set by server.

I've tried setting the variable in *.js like this;

function dummy(){

var myText = '#(myText)#';

}

However it seems like the webserver doesn't understand this coding convention. The js file sent back to client set myText in dummy() with the hard-value #(myText)#. It's not the value of myText variable in server side.

I know I can achieve this by putting dummy() directly in csp file. However I have to put dummy() in separated file, so that other files can use it.

My current work-around

Hello,

Has anybody successfully taken a recordmap business service to business operation integration and converted it into a Batch pipeline?  I am trying to wrap my head around the documentation (https://cedocs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=EGDV_recmap_batch) and cant seem to get this to the finish line, what I end up with is publishing a batch record with exactly one record in it in real-time while when I really want to excersise the RollOver limit of about 50 records.  I have no requirement for fancy headers or trailers, just multiple records.

Hi, 

I know there are several alternatives, but I would like to find the easiest & simpler ones to store data coming in Json format from post requests and also allowing me to do SQL queries. 

I want to have a property called favouriteColors. I want to store a few colors, and I want to be able to do queries to get top favorite colors, etc... so not handling the list of colors as just a fixed string or fixed object. 

If I want to store this information, I have several alternatives, like %DynamicArray, list of %String o maybe just %String, but I  want to find the best way to store the property in

I am using the SOAP Wizard in Studio to try to read in a WSDL file that is physically on our HealthShare server.    I keep getting the same error:

As I am not trying to connect via HTTP ( and I don't see anywhere to add an SSL connection), I am not sure what I am doing wrong.

Any suggestions & solutions gratefully accepted.

Hi,

I was wondering if there were any guides, similar to the ones for an upgrade, that walkthrough at a high/medium level the process for migrating an Ensemble Instance.

I am presuming that the general flow would be to install a fresh instance in the target environment, and migrate items over.. but any specific order? gotchas? things to avoid? Some things that should/shouldn't be im/exported (ie, must be manually migrated) ?

Doing some googling I found this page, and i have confirmed I don't need Endian xlation or DB Extent conversion.

We're going from Windows -> Windows , physical to VM

Does anyone have an anonymize script for SDA?

Hi All

When performing an update transaction on  patient data in GUI Apex 5.8 cache2017, we randomly get a ‘Database Connection Lost’ error. Subsequently the application quits and the incomplete transaction is rolled back.
 

We have confined its not a network issue as we can still query the database using CHUI Apex when these events occur.

so any input appreciated.

Someone have experience consuming special wss ?

I need generate this values on Iris :

for any help,  Thanks in advance

Has anyone tried using the TCPKeepAlive function?  I've been reading the documentation on this and it might be what I need to use.  Any examples of how this is being used?  thanks!

I have a C string and I need to build a $lb from it.

This code works fine for strings shorter than 254 characters:

char *str = "some string";
int len = strlen(str);
int add = 2;
char *list = malloc(len + add + 1);
char lenChar = len + add;
sprintf(list, "%c\x01%s", lenChar, str);

Thought maybe someone can share the code for longer strings?

The client part of the code for this game is on the MS Excel sheet and consists of:

1. m-commands  for random arranging ships on the playing field  (21 cells)
2. m-command to enable on-click m-trigger on all 100 cells of the playing field (1), red font
3. m-trigger (1), red font

The server part of the code (vmx.ro) is installed onсе, it not change depending on the task, is the same for IRIS, CACHE, 16, 8-bit encoding, any applications, games, reports.  The server side creates and maintains ‘virtual excel’ in M.

⏯ Durable Data Storage with Containers

Hello all!

As we ObjectScript developers have been experiencing, preparing an environment to run CI related tasks can be quite the chore. This is why I have been thinking about how we could improve this workflow and the result of that effort is IRIS-CI.

See how it works here.

Quickstart

1.Download the image from the Docker Hub registry:

docker pull rfns/iris-ci:0.5.3

2. Run the container (with the default settings):

docker run --rm --name ci -t -v /path/to/your/app:/opt/ci/app rfns/iris-ci:0.5.3

Notice that volume mounting to /path/to/your/app? This is where the app should be.

I am attempting to pragmatically create a bunch of roles and then assign the appropriate resources to that role.

Currently, the only ways to add resources to a role are to:

1. Do through Management Portal

2. Go through ^SECURITY (add resource one at a time)

My Intention would be to do the following: do ^SECURITY Role Setup Edit Role When prompted for resources to add, be able to use *

Additionally, I was thinking that an additional method can either exist (that I seem to can't find) or create a new method called AddResources: ##Class(Security.Roles).AddResources("role name", "resources to add

In my Data Transformation, the Target class needs to create a new List of objects (ListOfObj), depending on some conditions of Source class (Source/Target are completely distinct/different classes).

I experimented with Lists of 'primitive' data types (ListOfDT), and I could add new %String items (as an example) to a List of %String property, with "append" action in DT.

Does anyone have an example, or guidance, how to create new Lists of Objects in data transformation?

For example, if I have a 'container' class like this, it works:

Class Json.SalesOrderContainer Extends

Looks like the $get is actually trying to use the property getter instead of evaluating the GetAt as a method first.
Should this be considered a bug?
