I need connect to cache2016 database by python to get some data, but   I don' t know how to connect by python, did anyone know how to create connection？

If you can provide any python code, that will be better! 

Hi Friends ,

We have requirement to load data into chache tables from external database (ref data). This process will take 1 min to complete all data load.

Currently I have created Business Service  to trigger Business Operation with out bound db adapter to load data into cache tables.

process will be trigger when i restarted business service.

But requirement  is  , this business service should be triggered from outside ensemble environment i.e , this should expose as REST endpoint and share with the external team.

How to expose Business service as REST endpoint? I need help for this regard.

Thank

I'm wondering how I would go about adding headers to a csv file which has already been created. I am unfamiliar with ObjectScript. 

For example if I were to use R, I would simply write..

test <- read.csv("file/path/example/Extract.csv", header=FALSE)
colnames(test) <- c("A","B","C","D","E")

I do not have embedded Python installed either as I would know how to do it in that also.

How could I mirror this in ObjectScript please?

My current create file method:

Hi,
is there a way to know where IRIS or CACHE current instance is installed from objectscript?

Something like "iris list"

It will be easy to make a $ZF, iris qlist, and get the info, but i hope that there's something less complex than that.

Thanks

Pietro

Hi,

I have a IRIS mirror set

. all running on SUSE Linux

. each on a separate server

consisting of

Primary

Backup

Arbiter

My arbiter is the ISCagent.

Question

=======

Is there a Linux command showing me the status of the ISCagent as arbiter?

The systemctl service command below shows if the service is running but not if it is acting correctly as an arbiter.

I'm looking for a command like iris list which you can run on the Primary or Backup

===

systemctl list-units --type=service|grep -i isc
ISCAgent.service                                                                          loaded active running

Hey Community,

Here is a digest of the Developer Community videos on InterSystems Developers YouTube Channel in February 2023:

Hi Friends,

I have created one utility method to check given id exist some reference table or not. If exist the method return1 otherwise 0.

But some times the backed table data will be reload with another process (REST request) , on any point of time. This reload process max it will take 30 seconds.

My Requirement is , the utility method should wait , if table reload is in progress.

Could you give me any suggestion for this issue.

Thanks,

Prashanth

This tutorial is a follow on to Working with %Query    
It was displaying the content of the input stream chopped in fixed-size chunks.
But often those streams are structured and have well-defined separators (e.g HL7)
So as a side subject of this tutorial, this chapter shows how to break a stream into PIECES.

It is exactly the same idea as the $PIECE() function for strings with some add-ons.

My previous article introduced you to SQL based Basic Class Query
where a clever wizard created all the required code for you and your essential
contribution was an SQL statement. 

Now we enter the real Custom Class Query that provides more freedom but
requires a deeper understanding of the mechanic behind the scene.
The full code example is again on GitHub

My previous article introduced you to the COS based Custom Class Query.
There were some features missing like more lines of the stream displayed
and numbered.

Is there a way to do something like $SYSTEM.OBJ.ExportAllClassesIndividual() for the routines?

I'd like to export all routines in single files

I am new to setting up a mirror environment....

We will have a Arbiter, Two Failover members (A,B), and a Async (DR) member (C). I have the two failover members in sync and are configured for Arbiter Control.

My question is about the Async member, when I initially set it up I pointed it to the mirror on the primary node A.

Is that correct?

What happens to the Async member (C) if we fail over the mirror to the secondary member B?Does there need to be a VIP just for the mirror outside of the VIP we have for our systems to connect too?

Introduction

This is a simple tutorial on the quickest way I found to create a sample database for any purposes such as testing, making samples for tutorials, etc.

Creating a namespace

1. Open the terminal
2. Write the command "D $SYSTEM.SQL.Shell()"
3. Write "CREATE DATABASE " and the name you want for your namespace.

Now you have a new namespace in a faster way than creating it from the Management Portal - which of course offers way more configuration options.

To select it, quit the SQL Shell writing "q" and then typing 'zn "namespaceName"'.

Hi Guys,

I'm using the below code but I'm getting an uncomplete JSON file, so it seems that the command S obj=Httprequest.HttpResponse.Data.Read(Httprequest.HttpResponse.Data.Size) is not reading the whole file, so maybe the file is too big so is there a max size or can I change something in my call ?

The uncomplete file that I received so far is about 3.5MB 

set Httprequest = ##class(%Net.HttpRequest).%New()
  Set Httprequest.SSLConfiguration="RTLS"                              
   Set Httprequest.Server="vibra-api-prod.azurewebsites.net"                 
  Set Httprequest.Https=1

Hi Developer Community! 

Learning Services is always looking to improve -- and we want to hear from you! Please take this 3-minute survey to tell us what you think.

Hello everyone,

As someone who is new to the world of InterSystems technology, I have been looking for the best resources to learn more about it.

I have heard great things about InterSystems technology, particularly its speed and scalability, and I want to make sure I have a solid understanding of it before diving in further. From what I understand, the official InterSystems courses cover a wide range of topics and are taught by experts in the field.

I would appreciate any recommendations on which courses to take, particularly if there are any that provide a good foundation for beginners.

I have pdf documents stored in repo edge HS.IHE.XDSb.Repository.Documents. Is it possible that this can further compress this type of binary stream?

below is the code I can see but Is this applied on 2021.1?

Property Document As %Stream.GlobalBinary;

Class %Stream.GlobalCharacter Extends TmpCharacter [ System = 2 ]
{Parameter COMPRESS = 1;}

Is there a way to escape a comma in a comma delimited list? (ObjectScript)

Example: In("Connected, Connected, but issues, Not Connected")

(How) can I escape the comma in the 2nd value?

Thanks,

Brian

Does anyone have insight into how the Stream Global Compression works in 2022? I'm particularly interested in the XDSb repository on the Edges. As I understand it anything new will be compressed. Is there a compression method that is used that can be utilized by other code? How are the retrievals aware that the contents are compressed in order to de-compress them? 

Hi,

Question about ZMIRROR routine.

I analyze a problem with the label NotifyBecomePrimary. It seems not performed after a switch.

After installing ZMIRROR routine in %SYS, is a restart required?
If It's required, It could be explain my problem.

Thank you.
