In the sample below, an image file is encoded into a Base64 string in a class property, saved, decoded again with Base64, and restored to another file.

【Usage class】

Class User.test Extends %Persistent
{
Property pics As %GlobalBinaryStream;
}

【When importing】

  set x=##class(User.test).%New() // create a new object

  // prepare an image
  set file=##class(%File).%New("c:\temp\Mii.png")
  do file.Open("RUK\BIN\")
  for {
       if file.AtEnd=1 quit
       // Convert image to Base64 format in chunks of 1024 bytes
       set cnt=file.Read(1024)
       set b64=$system.Encryption.Base64Encode(cnt) // b64: 1402byte
       do x.pics.Write(b64)
  }
  do x.%Save()
  do file.Close()

On Linux, use the iris command to execute a routine or method from a shell and get the return value.

For more information,  please refer to the document "About Instance Connections".

An example of a command is as follows.

iris terminal instname [arguments]

The return value of a shell script can be specified using a special variable using the Terminate() method of the %SYSTEM.Process class when the process ends, rather than by specifying an argument in the QUIT or RETURN command that is specified when a routine or method ends. Use the method of returning a value to $?

Is it possible to have a single MUMPS variable representing all subscripts for a global? For example, if I have an ^ABC global and the ^ABC(1,2) node exist, is it possible to have a variable TEMP so that ^ABC(TEMP) would represent ^ABC(1,2)? TEMP="1,2" obviously does not work since it is interpreted as a single subscript, not two subscripts.

Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. In the previous part, we created a basic front-end React application. In the second part of this article series I will show how to choose the right back-end technology for your application. You will see Caché allows you to use many different approaches to link your front-end to your Caché server, depending on your application's needs. In this part we will set up a back-end with Node.js/QEWD and CSP/REST. In the next part we will enhance our basic web app and connect it to Caché using these technologies.

We are retiring a hosted application for an electronic health care records (EHR) system which stored the data on Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2017.2.2 (Build 867_4_20245) Thu Oct 8 2020 16:58:40 EDT.  The hosting company is providing me with a single CBK file.  I need to install a database system to restore the database and provide occasional SQL access for reports when necessary.  I'll need to maintain access to the data for an approximately 10 year retention period.

Need your company a help developing projects on Intersystems Caché /  Iris plataform?

Hello,

I need to ensure that the task created/scheduled, by system user, is created in the routine database and not remotely in the ECP to which it is connected. How can I guarantee the creation/scheduling of this task?

Here is a suggestion for creating the routine in both environments:

Is there another option?

Hi,

I'm trying to configure a specific process which dynamically sends messages to different endpoints based on datalookup keys, I've configured this aspect. What I'd like is to be able to visually see these connections without hardcoding them so is there a way to dynamically link them, i'll share what I tried below.

Thanks.

ClassMethod OnGetConnections(Output pArray As %String, pItem As Ens.Config.Item)
{

//Set pArray(..#endpoint)

 DO pItem.PopulateModifiedSettings()

&SQL(SELECT %DLIST(KeyName)
INTO :OutBoundlist 
FROM Ens_Util

Is there any built-in functionality to send out an email or a text message when a mirror member fails?

The meaning of each timeout value is as follows.

1. [Server response timeout]

If IRIS/Caché processing (routine or query execution) does not finish within this set time, the browser will return an error.

For example, if this value is 60 seconds and it takes 90 seconds to execute a routine/method/query, an error will occur.

2. [Queued request timeout]

For each IRIS/Caché server configured in CSP/REST, you can limit the number of processes that can run CSP/REST concurrently.

Hi,
I am dealing with a very old code base (some routines date back to 1985 and were running on a M system 😉). It is rather huge and currently contains around 5000 compilable *.int routines.

My goal is to export all routine code as *.int UDL files and setup a git repository containing all routines.

The issue is, approximatively 200 of those routines have storage names that differ only in case. I am using Windows and when exporting those routines using vscode, files gets overwritten depending on routine export order, as Windows NTFS file system names are not case-sensitive.

Hello InterSystems Community Members,

I hope you are all doing well. I am currently facing an issue while trying to set up the SNMP subagent functionality for my InterSystems Cache installation.

I am using InterSystems Cache for Windows (AMD64) version 5.2.4 (Build 809_0_9006U). The SNMP subagent functionality requires the iscsnmp.dll dynamic library, which I have been unable to locate in my installation directory.

I have checked my installation directory thoroughly, typically located at C:\InterSystems\Cache, and its subdirectories, but I couldn't find the iscsnmp.dll file.

As the iscsnmp.dll

It can be retrieved using the schema INFORMATION_SCHEMA.

INFORMATION_SCHEMA is a system schema and is not displayed by default in the SQL menu of the Management Portal.

The method to display it is as follows.

1. Open Management Portal → System Explorer → SQL menu.
2. Check "System" on the left of the schema drop-down.
3. Select INFORMATION_SCHEMA from the schema dropdown.

The SQL to get the ID, field name (COLUMN_NAME), data type (DATA_TYPE), description (DESCRIPTION) for the specified table (Sample.Human) is as follows.

Currently, the SQL privileges (SELECT, INSERT, UPDATE, DELETE) are managed at the tables level, which can be very tedious when you have to administer many roles in an organization, and need to keep them sync with a constantly evolving data models.
By managing privileges at the schemas level, will allow to give SELECT and other DML privileges to *all* or *several schemas* to a role|user, fixing the need to manually synchronize the new tables|views to the roles.

If you agree, I invite you to vote for this idea.

We often get questions about recent and upcoming changes to the list of platforms and frameworks that are supported by the InterSystems IRIS data platform.  This update aims to share recent changes as well as our best current knowledge on upcoming changes, but predicting the future is tricky business and this shouldn’t be considered a committed roadmap. 

With that said, on to the update…

  • RHEL 9.2 & RHEL 8.8 were released in May, 2023. Red Hat is planning to support these releases for 4 years.

Hello Everyone,

We currently have CSP application that runs under 2 servers(usually primary), and every month the server reboots for patching SERVER1(primary) in the morning and SERVER2(backup) at night.

Whenever the SERVER1 reboots SERVER2 behaves as primary and when SERVER1 comes back up it will act as backup server.

First Patching:

So, when SERVER1 is down, I need to start httpd service for SERVER2 and stop httpd service for SERVER1 (which is now backup server).

I tried using the code below in terminal to start httpd service for SERVER2 with no success.

Hi all,
I am trying to execute a query like the below code.
set statement = ##class(%ResultSet).%New("some_class:query_method").   // here query method is empty and with rowspec some columname

statement.Execute(param1)

I want to fetch data type of column value returned from above. eg - Name - VARCHAR, amount - INTEGER etc.
How can I get it. Or if not possible directly. Is there any other way to validate or get datatype of values returned. Line we have type() in python3

You can avoid the error by specifying a stream object as the argument of %ToJSON() used when generating a JSON string from a dynamic object.

A code example is below.

USER>set##class

I'm working with clients planning migrate from Caché to IRIS and I want to summary advantages to go to IRIS. I think is:

1. IntegratedML - AutoML - Agile machine learning
2. IAM - InterSystems API Manager
3. Interoperability
4. Advanced Reports (JReport)
5. Cloud Manager/Docker and DevOps support
6. ZPM - Package manager
7. Native API - Node.js, Python, Java and .NET interoperability
8. Core based license x user based license
9. InterSystems Support and new features
10. Improved management and monitoring features

Can you help me to think or detail these 10 topics?

The program below works perfectly when I call it directly from the Terminal, however when I call it from within a CSP it does not work (It does not do the SELECT).

In the USER namespace, the program works both in the Terminal and on the CSP , but in another namespace it only works when called directly in the Terminal.

PropList(class) ;
 k pl S c=0 s class="'"_class_"'"
 K ^PropList s ^PropList=class
 S lista=$SYSTEM.SQL.Execute("SELECT * FROM Projet.GerePageCSP")
 while lista.%Next() {
 S c=c+1,pl(c)=lista.

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD
• Why containers?
• Containers infrastructure
• CD using containers

In the first article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software.

In the second article, we covered GitLab Workflow - a complete software life cycle process and Continuous Delivery.

In the third article, we covered GitLab installation and configuration and connecting your environments to GitLab

In the fourth article, we wrote a CD configuration.

In the fifth article, we talked about containers and how (and why) they can be used.

In the sixth article let's discuss main components you'll need to run a continuous delivery pipeline with containers and how they all work together.

In this article, we'll build Continuous Delivery configuration discussed in the previous articles.

By specifying the start and end values ​​of the IDs for which you want to rebuild indexes in the arguments of the %BuildIndices() method provided in the persistent class (=table) definition, you can rebuild only the indexes within that range.

For example, to rebuild the NameIDX index and ZipCode index in the Sample.Person class only for ID=10 to 20, execute the following code (the ID range is specified in the 5th and 6th arguments). 

 set##class

$LB() is the $ListBuild() function. The %BuildIndices() method uses it to specify the index name.

The FHIR® SQL Builder, or Builder, is a component of InterSystems IRIS for Health. It is a sophisticated projection tool used to create custom SQL schemas using data in an InterSystems IRIS for Health FHIR repository without moving the data to a separate SQL repository. The Builder is designed specifically to work with FHIR repositories and multi-model databases in InterSystems IRIS for Health.

The objective of the Builder is to enable data analysts and business intelligence developers to work with FHIR using familiar analytic tools, without having to learn a new query syntax.
