Hello community,

I am trying to parse the below HttpResponse in Cache. Cannot get the Iterator to work. Is there a single loop which can parse both or single messages and grab the error?

{
error:[
{ txt1:'error msg1'},

{ txt2:'error msg2'},
]
}

{
error: {
txt1:[
'error msg1',

'error msg2'
]
}

Thanks,

Jimmy Christian

Serializing Python objects in globals

Motivation

This project was thought of when I was thinking of how to let Python code deal naturally with the scalable storage and efficient retrieving mechanism given by IRIS globals, through Embedded Python.

My initial idea was to create a kind of Python dictionary implementation using globals, but soon I realized that I should deal with object abstraction first.

So, I started creating some Python classes that could wrap Python objects, storing and retrieving their data in globals, i.e., serializing and deserializing Python objects in IRIS globals.

I am currently working with someone who is in the process of moving an application written in Cache Object Script over to a Windows server. It was previously running on a Linux server so all of the paths are unix style paths. Is anyone aware of a way to have cache remap paths to different paths so this user won't have to go through all of the scripts and change them?

Count Number of Pages?

Hello,

We are working on creating a metadata file to accompany PDF documents produced by one of our third party systems for ingestion into our DMS. One of the pieces of data that the metadata file must contain is the number of pages of the PDF document.

In Cache ObjectScript does anybody know if there is currently a way of counting the number of pages within a file (specifically a PDF) without invoking a non-Caché ObjectScript program/function from within Caché ObjectScript?

We are planning to use Caché users on a SOAP web-service, so the WS-security tokens will be used.
It will be username and password only for now.
The passwords should expire on a regular basis and this will be configured in the system-wide security settings.
The consumer of the web-service should be able to change their password on-demand or when it has expired, via a web-service call.

For the on-demand change, I can create a service method which can be called by the consumer to change the password.

I am experimenting with Relationships, both Parent to Child and One to Many.

I have done some SQL look-ups and have searched through the documentation, however not in a lot detail, but wonder if there are more and better ways to access both sides of Relationships through SQL?

Thank you in advance for any help provided.

Windows write caching

(This article was reviewed in February 2021. It is still relevant to Caché-based installations and similarly applies to IRIS-based installations.)

This article discusses the Windows write caching setting which can leave systems vulnerable to data loss or corruption in the event of power loss or operating system crash. The setting is on by default in some Windows configurations.

Hi,

I'm unable to locate a set of instructions that would allow me to encrypt the traffic to/from the Cache' Management Portal (that is - run it over HTTPS)

I am referring to the Management portal as hosted by the private Apache Web server instance installed with Cache. (I know how to do this for regular web sites hosted on, for example, IIS).

I would imagine the steps would involve, (a) enable SSL on that apache instance and (b) deploy certificates into the Apache web server.

Does anyone have a step-by-step guide on how this is accomplished ?

Hi,

I would like to know if anyone has had some experience in building systems for multiple end-users.

To keep things simple, in a hypothetical example, say an Event Booking System, where a Venue could sign up to use such a system and define it's Venue, costs, calendars, etc.. and then invite their customers to book the Venue on different days/times.

If I wish to offer such a system to many Venues, there are a number of options available.

problem with Mirroring

Hello, Thanks in advance for all replies. I have been practicing setting up mirroring between two development servers in preparation for mirroring our production server in a few weeks. I started by setting the servers up with minimum security which worked easily, then I set it up in lock down mode again without any issues. Now I am setting it up in lockdown mode with encryption and this one is testing me. I have everything setup but my async dr member cannot connect to the primary.

Hi,

We recently updated Ensemble, on our Unix DEV server , from version 2013.x to 2015.2.3 (Build 855U) and when we test our SSL/TLS configuration we get the following error:

ERROR #729: Certificate /qmd/ens_chldev_1/mgr/SILCert/SILCSSSJR-CER.cer is not valid for TLS Web client authentication .

The certificate was working fine before the update in DEV and it is working fine in our PROD Unix server with Ensemble 2012.x. Any ideas why we are getting this error?

Convert HL7 to FHIR

Hello Greetings-

I am exploring on converting HL7 to FHIR.

1. I saw there are built in DTLs “FHIR.FromSDA” and “FHIR.ToSDA” to convert SDA -> FHIR and FHIR -> SDA. Similarly Do Intersystems have DTLs for HL7 -> FHIR and FHIR -> HL7?

2. The reason why I am asking is, I see in HSLIB namespace HS->GateWay->HL7->HL7toSDA3 and HS->GateWay->SDA3->SDA3toHL7 DTLs. Like-wise I am trying to locate HL7 -> FHIR and FHIR -> HL7. Please help me to locate them

The object and relational data models of the Caché database support three types of indexes, which are standard, bitmap, and bitslice. In addition to these three native types, developers can declare their own custom types of indexes and use them in any classes since version 2013.1. For example, iFind text indexes use that mechanism.

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?

ZPM is now InterSystems Package Manager (IPM)

I'm pleased to announce a milestone in the lifecycle of the ObjectScript package manager, ZPM. The package manager has offered developers the ability to neatly package up ObjectScript code and deployment configuration settings and version information in a convenient way. Over the last few years, it has evolved greatly into an integral part of many development workflows.

This text is a continuation of my article where I explained the structure a Caché database. In this article, I described the types of blocks, connections between them and their relation to globals. The article was purely theoretical. I made a project that helps visualize the block tree - and this article will explain how it works in great detail.

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>
