Hi, everyone!


I want to share a personal project that started with a simple request at work: 

Is it's possible to know how many Caché licenses we are using? 

Reading other articles here in the community, I found this excellent article by  David Loveluck

A quick question regarding to SQL Query Plan:
Why these two requests have different plans, in particularly, why second request needs temp file? To me, temp file is a bad thing which should be avoided, right?

  1. select * from Test.Log where cdate = 1
  2. select * from Test.Log where cdate > 1

Plan for 1:

Read index map Test.Log.cdateIndex, using the given %SQLUPPER(cdate), and looping on ID.
For each row:
 Read master map Test.Log.IDKEY, using the given idkey value.
 Output the row.

Plan for 2:

Hello,

I am working on Ensemble 2017.2.1 .
I need to export my security settings into an extern database, in order to make a report.

I've created a Business Operation with an SQL Adapter into a Namespace, but I don't know how to get every security data from "%SYS" Namespace  ( SQLPrivileges , Resources , Roles , Services , Users ... ).

I dont't want to use the terminal and the ^SECURITY routine, because i don't want to store a XML file on the server.

Cache / Ensemble version 2016.2.2.853.0

I have a need to restrict ODBC access to certain users to prevent unwanted access to our cache database.

We have a limited number of legacy applications that use ODBC to connect to read data and are currently not in a position to have these amended any time soon so in the interim, I am hoping someone will be able to provide me with some assistance.

Any suggestions on where to start?

Hi

I'm using this query "Config.MapMirror.List" To get information of the list of servers that are in the mirror system.

I'd like to know how can I know which of the list is the primary and which is the failover or async member.

Is there a way to do it with this query? Is there another query to get this info?

Thanks a lot

Hello,

I am reading in an X12 document into my production that needs to be processed and returned as a CSV file.  I have created a record map to support the fields I want to extract with a batch class to store headers.  I have a DTL mapping the data to the appropriate fields in the record map and am sending the record map to a EnsLib.RecordMap.Operation.BatchFileOperation.

I'm trying to tie IRIS (2019.1) into our Concord Fax cloud-based email-to-fax workflow. We have some sites that require a fax be sent to multiple locations based upon certain data (ie Radiology and Emergency departments). Unfortunately, CC-ing does not work with Concord Fax so I need a way to send the email, change the recipient, and then send it again if certain criteria are met. Is this possible? Do I need to duplicate and rename the method, calling the second one in the MessageMap?

Here's what my code currently looks like:

Hello everybody,

My question would be, how is the recommended way to access Windows shares, also in view of future demads. Of course, I'm also happy about an explanation or code snippet of how the library, which is mentioned in the following , can be used under cache.

The classic jcifs library is easy to use, also with Cache, but as microsoft ceases support for smb1, we are currently looking for alternatives. jcifs-ng is such a library, which we took a closer look at. In java code a jcifs-ng file operation looks like this:

Hi,

 

I'm attempting to use the $EXTRACT function in my routing rule but I'm seeing 'Expression Parsing' error messages when trying to save the rule.

I want to check the last character of a post code by using the following code:

$EXTRACT(HL7.{PID:PatientAddress(1).ziporpostalcode},*)="Z"

Could anyone assist with this?

 

Thanks, 

 

Martin

Hello,

When we need to create a utf-8 encoded XML file, we  use the Charset property of %XML.Writer:

set writer=##class(%XML.Writer).%New()
set writer.Charset="UTF-8"

 

How can we create regular txt files with such encoding?

Our Cache Installations are 8 bit and not unicode.

 

Thanks,

Nael Naser eldeen

Hi Developers!

"objectscript.conn" :{
      "ns": "IRISAPP",
      "active": true,
      "docker-compose": {
        "service": "iris",
        "internalPort": 52773
      }

I want to share with you a nice new feature I came across in a new 0.8 release of VSCode ObjectScript plugin by @Dmitriy Maslennikov and CaretDev.

The release comes with a new configuration setting "docker-compose" which solves the issue with ports you need to set up to make your VSCode Editor connect to IRIS. It was not very convenient if you had more than one docker container with IRIS running on the same machine. Now, this is solved!

Read below how it works now.

Intro

For many in today's interoperability landscape, REST reigns supreme. With the overabundance of tools and approaches to REST API development, what tools do you choose and what do you need to plan for before writing any code?
This article focuses on design patterns and considerations that allow you to build highly robust, adaptive, and consistent REST APIs. Viable approaches to challenges of CORS support and authentication management will be discussed, along with various tips and tricks and best tools for all stages of REST API development. Learn about the open-source REST APIs available for InterSystems IRIS Data Platform and how they tackle the challenge of ever-increasing API complexity.
The article is a write-up for a recent webinar on the same topic.

Hi Developers!

Recently we released the updated version 0.1.3 of ObjectScript Package Manager (ZPM) which comes with the support of simplified ObjectScript sources folder structure.

What 'simplified' does mean?

Before 0.1.3 ZPM expected the following structure:

/src

---/cls  - for ObjectScript classes

---/cls/package_name/class_name.cls

---/cls/package_name/class_name2.cls

---/mac - or Mac ObjectScript routines

---/mac/package_name/mac_routine.mac

---/mac/package_name/mac_routine2.mac

---/inc - for ObjectScript macro include files.

---/inc/package_name/include_file.inc

Hi all,
I'm having issues with mounting custom database on top of IRISHealth 2019.1 docker container. Data gets mounted only in Read-only mode. This means read operations are successful but I couldn't make the image  with databases mounted  in Read/write, both modes. Is anyone having similar issue?

In this post I show strategies for backing up Caché using External Backup with examples of integrating with snapshot based solutions. The majority of solutions I see today are deployed on Linux on VMware so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

Ok so I am way outside of my comfort zone, and had to build an application using CSP to give users the ability to access SQL configuration tables. These SQL Configuration tables will affect the data that is sent to the downstream system. 

I saw in the examples where we were able to import GIF's/IMAGES into the CSP folders to use as a reference in our CSP pages. My question is how do you do that? If I try to import through studio, it tells me the file is invalid.

Just trying to make it a little more user friendly then blocks on a page.
