Hi All!

I asked previously about the DR server in the cloud but actually, I'm curious about the backup server to use as analytics server more than for recovery in DR case.

There is a recommended practice to use an async mirror as a server for BI (InterSystems Analytics, DeepSee)

The question is if I have PRIMARY in the cloud (AWS, Google, Azure, etc) "how far" should async mirror member be placed? Same cloud, same private cloud or it doesn't matter at all for analytics purposes?

Sometimes global mapping of the same globals can be defined in different ways. E.g., I need to define it for 3 globals ^qAuditC, ^qAuditLog, ^qAuditLogC from the same database named APP-NOJOURN. Which approach should be better from the performance point of view?

1) qAudit* => APP-NOJOURN (one record in global mapping table)
or

2) qAuditC => APP-NOJOURN
qAuditLog => APP-NOJOURN
qAuditLogC => APP-NOJOURN (three records in global mapping table)

Node.js using SQL query

I am attempting to use Node.js to perform a simple query against the database using some identifying information to get the ID. This is what I am attempting to do:

var irisobj = require('iris');
var myData = new irisobj.IRIS();
var result = myData.open({ path:"C:/InterSystems/IRIS/Mgr",
username: "USERNAME",
password: "PASSWORD",
namespace: "YOURNAMESPACE"
}
);

Is there a way to set null in dynamic object without using %Set methods?

I have this method and I need to set NULL as, well, null and not string.

ClassMethod node(name) [ CodeMode = expression ]
{
{
    "name":(name),
    "content":($case(##class(%Dictionary.ClassDefinition).%ExistsId(name), $$$YES:"mycontent", $$$NO:"NULL"))
}
}

Hello everyone,
It is my first post in the community. Very recently I started working using IRIS, creating services with Cache.
Today they gave me a new task and I'm really lost.

How can I use an oracle database to create services using iris?

Throughout the day I was looking for a guide to use a remote Oracle database. but unfortunately I only managed the connection in SQL Gateway

Can anyone clarify to me about the differences between these two classes?

People in this topic https://community.intersystems.com/post/using-class-queries-sqlstatement-versus-libraryresultset stated that %SQL.Statement (I am assuming they mean to talk about %SQL.StatementResult) is newer than %Library.ResultSet. But I don't really know what are the advantages of %SQL.Statement over %Library.ResultSet as the people in the topic somehow didn't mention them.

Hey,

I am pretty new to Docker and everything around that. I installed the container image from DockerHub and followed the instructions (https://hub.docker.com/_/intersystems-iris-data-platform/plans/222f869e-567c-4928-b572-eb6a29706fbd?tab=instructions). Everything is working fine except for the part where I want to change the default password.

Good evening Intersystems Community,

I want to participate in the Advent of Code 2020 and followed the installation instructions in "The Advent of Code 2020 contest ObjectScript template" (https://openexchange.intersystems.com/package/aoc2020-objectscript-template).

Unforunately I get "Error: Invalid Community Edition license, may have exceeded core limit." at the step "docker-compose build".

I have an SQL text index defined like this

Index TextIndex On (Text) As %iFind.Index.Basic(IGNOREPUNCTUATION = 1, INDEXOPTION = 0, LANGUAGE = "en", LOWER = 1);

If I run a query like this:

SELECT
Text
FROM Post
WHERE %ID %FIND search_index("TextIndex",'ABC')

I get 20 results with posts containing the term ABC.

But each post can contain the term ABC several times.

Hello,

I have established an ODBC connection with our client based on credentials they provided. The test connection was successful and after using the Link Table wizard I can now see the client's tables and properties. However when we try to execute a query in IRIS we are getting error code -226. I'm trying to determine if this could be just a simple setting problem in IRIS or something with the client.

We have tried with PostgreSQL as well as with TSQL. Same result for each.

Hi all,

I'm looking for a user-friendly way to make a method library available in DTL, and by user-friendly I mean via '..MyMethod()' or '$$$MyMacro()' rather than '##class(MyPackage.MyClassName).MyMethod()'.

Does anybody know of a way to add a second superclass or a set of macros to a DTL ... or some other trick?

Cheers,

Otto
