Hello,

I’m creating a REST API service but I need to convert my object in JSON.

The Class “A” is extended from another Class “B”:

Class message_B Extends Ens.Request
{

Property ClientId As %String(MAXLEN = "");

Property mesagge As %String(MAXLEN = "");

}

Class message_A Extends message_B
{
Property idDate As %String;

Property Datetime As %String;

Property time As %String;

​}

When I use:

Hi All,

I am receiving this alert every couple of minutes. I am trying to figure out what is causing this and if it is just the settings on my TCP operation or if this indicates an actual issue. Is it an issue with my framing (MLLP) or reply code actions (not set)? Something else?

Error:

ERROR <Ens>ErrTCPTerminatedReadTimeoutExpired: TCP Read timeout (30) expired waiting for terminator SegTerminatorAscii=13, on |TCP|7049|12692, data received =''
(alert request ID=2071)

Hi

I've got a string variable which I need to convert into a XML one.

My main goal here is to use the XML bit I've extracted from a HTML file in a message I need to pass over to an operation.

I'm doing the following which always errors

classMethod WriteNodes(myfile As %String)
{
Set status=##class(%XML.TextReader).ParseString(myfile,.reader)

....

Any easy way of making this happen?

Kind regards

Below is a simple alert processor based on the EnsLib.HTTP.OutboundAdapter to send text alerts via an SMS Gateway service. Typically, all that is needed to send an HTTP Post to the gateway service is the destination phone number, a source phone number, credentials, and the URL.

The code below is based on the Anveo gateway whose interface is as follows:

This is the first in a pair of articles on SQL indices.

Part 1 - Know your indices

Based on user request in zenpage, i am running the method ConvertMDXtoJSON in background and loading the status in progressbar.

D ..%RunBackgroundMethod("ConvertMDXtoJSON",MDX)

From this background method ConvertMDXtoJSON() i want to return the value(sjson) and store it into session.

How can i do this?

Below is my code.

Recently I have been posting some updates to our JSON capabilities and I am very glad that so many of you provided feedback. Today I would like to focus on another facet: Producing JSON with a SQL query.

Hi Everyone,

I am trying to built a SSIS package thru BIDS Visual Studio 2013. My Datasource is a InterSystems Cache Database, I wanted to Import Tables records from the Datasource to MS SQL Server 2014.

As a Sanity check. I only created one Package to import one Table to MSSQL Server to try out. The connection to the InterSystems Cache Database was successful. The DSN for the InterSystems Cache Database is created in the System for 32 and 64 Bit.

Hi Developers!

Recently we launched InterSystems Package Manager - ZPM. And one of the intentions of the ZPM is to let you package your solution and submit into the ZPM registry to make its deployment as simple as "install your-package" command.

To do that you need to introduce module.xml file into your repository which describes what is your InterSystems IRIS package consists of.

This article describes different parts of module.xml and will help you to craft your own.

I will start from samples-objectscript package, which installs into IRIS the Sample ObjectScript application and could be installed with:

zpm: USER>install samples-objectscript

It is probably the simplest package ever and here is the module.xml which describes the package:

<?xml version="1.0" encoding="UTF-8"?>
<Export generator="Cache" version="25">
  <Document name="samples-objectscript.ZPM">
    <Module>
      <Name>samples-objectscript</Name>
      <Version>1.0.0</Version>
      <Packaging>module</Packaging>
      <SourcesRoot>src</SourcesRoot>
      <Resource Name="ObjectScript.PKG"/>
    </Module>
  </Document>
</Export>

Server:

The technology of load balancing between several servers with relatively low capacity has been a standard feature of Caché for quite a while. It is based on the distributed cache technology called ECP (Enterprise Cache Protocol). ECP provides a host of possibilities for horizontal scaling of an application, and yet keeping the project budget fairly low. Another apparent advantage of ECP network is the possibility to conceal its architecture in the depths of Caché configuration so that applications developed for the traditional (vertical) architecture can be fairly easily migrated to a horizontal ECP environment. The ease of this process is so mesmerizing, that you start wishing it was always this way. For instance, everybody is used to having a possibility to control Caché processes: the $Job system variable and associated classes/functions work magic in skilful hands. Stop, but now processes can end up being on different Caché servers…

This article is about how to gain as much transparency in controlling processes in ECP environment as in traditional (non ECP) one.

hi

I cannot connect to Caché sometimes, the error message is

[Cache JDBC] Communication link failure: Communication error: Connection reset

and I cannot access the management portal

so I plan to restart Caché with "ccontrol stop cache"， it prompted "unable to get access to pid table"

what's the problem?

thanks!
