Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good ). You can download from GitHub and compile it into your system, generate sample data and play a bit with it. It's done for InterSystems IRIS but it also should work in last

Question David.Satorres6134 · Aug 19, 2019

Hi all,

One of the most useful features for me in IRIS was the queue page. From there, I could see how the different elements (BS, BP & BO) from a production were behaving, thanks to the possibility of auto-refresh every second. Great thing.

But we have updated to 2019.1 and this possibility is gone... we need to refresh manually! So, is there any way to set a parameter somewhere to have the queues status refreshed automatically?

Thanks a lot.

 I have two local instances:

  • IRIS for Windows (x86-64) 2018.1.2 (Build 626_3U) Wed Jun 12 2019 19:07:59 EDT
  • IRIS for Windows (x86-64) 2019.1 (Build 510U) Thu Mar 14 2019 14:13:37 EDT

I'm using Java Gateway to talk to external system.

Both instances are using the same:

  • jar
  • generated class
  • java version


They are calling the same method with this java signature:

package isc.rabbitmq;
public class API {
    public void sendMessage(byte[] msg) throws Exception {}
}

On the InterSystems IRIS side I'm calling it like this:

Hi,

Is there any way to set environment variables in Linux from Cache?

I see a way to get an environment variable with: $system.Util.GetEnviron()

Essentially I am converting from VMS (DCL) to Linux.

In VMS we used $ZF(-1,"SETSYM") in Cache to a value and then interpreted that value in a DCL procedure.

The newer dynamic SQL classes (%SQL.Statement and %StatementResult) perform better than %ResultSet, but I did not adopt them for some time because I had learned how to use %ResultSet. Finally, I made a cheat sheet, which I find useful when writing new code or rewriting old code. I thought other people might find it useful.

First, here is a somewhat more verbose adaptation of my cheat sheet:

I have a list property that I query from the database to get the values contained in that list using $LISTFROMSTRING() when the list is returned the list values contain a rectangle like character similar to when you copy past something to the Terminal and it has a preceding space .The problem is I need to compare those values to other values and they do not match because of this value I have tried to use $EXTRACT(value,*W) and *P but this is not striping the preceding character how do I get rid of this character any ideas please. 

the values returned from the Database

We have created a custom SDA container to store a certain kind of new, customized patient data.

We are observing a behavior in the correspoding analytics table for this custom SDA class where rows are added for a patient for which the MPI is null and the patient record does not exist.

Hi

Is there any way to control what control sequence is sent to a device when a   "write #" is executed?

I have an application that establishes a banner at the top of the terminal window and when we do a   "write #" the banner disappears.  I need to be able to recreate the banner line as part of the screen clear.

Thanks

I have an OAuth 2.0 development environment where Caché is serving all three roles as the Authorization Server, Client and Resource Server based on a great 3-part series on OAuth 2.0 by @Daniel Kutac. I have a simple password grant type where an x-www-form-urlencoded body (as described in this post) is sent as a POST to the token endpoint at https://localhost:57773/oauth2/token and a response body with a HTTP Response 200 header is returned. The response body looks something like this.

Hi,

I am trying to use the  LogicialToDate method in the %Library.FilemanDate class.  In the class documentation it talks about the parameter STRICTDATA (see below).  I would like to set the STRICTDATA to a 1 but I am not sure how to do that when using this method because the method does not reference this as a parameter to be passed into it.  (see below).

How do I set the parameter?

Thanks

parameter STRICTDATA = 0;

Hello,

How should I go about it to add a page to the EnsPortal? I want to display a dashboard like page and I would like to be able to have it accessible from Management Portal. I hope there is a better way than typing the URL in address bar. Is the menu for Management Portal editable?

Thanks,

Oliver

Question Robert Marsden · Aug 12, 2019

Hello All.

In need of some help.

We are currently migrating Interfaces from JCAPS to HealthConnect 19.1 and have done a lot of work on our Dev server.  I am looking to copy/export this work over to the Test server and have managed to export the production and Rules, HL7 custom Schemas etc.  The only thing left now are the Data Transformations but so far I can only find ways of copying the transformations over individually.  Is there some way to copy all of the transformations we have produced in our namespace to another server in one go?  

Thanks

Hello everyone,

I was first introduced to TDD almost 9 year ago, and I immediately fell in love with it. 
Nowadays it's become very popular but, unfortunately, I see that many companies don't use it. Moreover, many developers don't even know what it is exactly or how to use it, mainly beginners.

Overview

My goal with this article is to show how to use TDD with %UnitTest. I will show my workflow and explain how to use cosFaker, one of my first projects, which I created using Caché and recently uploaded to OpenExchange.

So buckle up and let's go.

What is TDD?

Question Robert Gasper · Aug 8, 2019

Just wondering if anyone knows if there is a way to get daily emails or alerts about changes to a cache database.  I know that all of that information is contained within the journal files, just wondering if there is a way to bundle it up each day and send it off for auditing, etc.

Any solution where a plain-text/readable format of changes to the cache database could be sent or stored for review would solve the issue.

Thanks!
