After installing IRIS 2023.1 on a live copy of our production machine our REST Service now consumes a CSP Session with every request. The request is handled as expected, but uses one of the 5 CSP Session per license. So after 25 requests, the license is used up. The Grace time always shows 0 and the session stay for very long. (Maybe the 900 Seconds timeout). 
On Caché 2018, we had the same settings for the Webapp and there, only a single Session was set for all requests. The Caché request didn't use any cookies. 
Here we also used  $system.License.

There are several ways of classifying cryptographic algorithms: 1) Secret Key Cryptography (SKC) - Uses a single key for both encryption and decryption. It is also called symmetric encryption. Primarily, it was used for privacy and confidentiality; 2) Public Key Cryptography (PKC) - Uses one key for encryption and another one for decryption. It is also called asymmetric encryption. Initially, it was utilised for authentication, non-repudiation, and key exchange; 3) Hash Functions - Uses a mathematical transformation to irreversibly "encrypt" information, providing a digital fingerprint.

Some time ago I introduced a new driver for Django for IRIS. Now, let's see how to use Django with IRIS in practice.

SQLBuilder is a flexible and powerful SQL query string builder for InterSystems IRIS,

With SQLBuilder you have nice and clean object oriented methods, instead of having to use concatenation and substituition to generate dynamic queries.

Hibernate is the most popular framework to do ORM (Object Relational Mapping) projects. With Hibernate a software can use the main DBMS in the market, including the capability to change the database vendor any time, without source code impact. This is possible because the Hibernate supports dialects. Each database product has a different dialect that can be assigned into a configuration file. So, if a software is using Oracle and is looking to evolve to InterSystems IRIS, just change the configuration file with connection and dialect information.

Hello,

I am looking for information about garbage collector. I already looked at documentation but I could not find anything about it.
Here is some questions :

1) is there a garbage collector per process (each process has it's own memory and GC is done per process) or is it global (eg: shared memory) ?
I know there is some memory allocated per process at startup but also globally (gmheap).
2) when a GC / cleanup occurs somewhere,  is it possible that it block the other processes for a short moment ? (eg: a "stop the world" GC that pause everything while job is being done).

Hi,

     I am trying to load all the data tables from one iris server to a client server but some of the tables data failing to load all the time. But I can load around 100 tables successfully  but 8 to 10 tables are failing all the time. I made an IRIS odbc connection using odbc driver to load the data from tables.

Also I can see read server loop error message on the iris server side as the same time the table loading fails.

Please find the screen shot attached which shows the error on client server.

Can anyone provide me an advise how to fix the issue.

Thanks

Iris DAT file is filling up  the Internal Storage with available Free Space to Zero. Is there any Alternative measures to reduce the File size or to control the Capacity.  Is there any chance to save Local storage. 

Once the Local Storage is full, Production is not responding and throwing Out of Space Error.

Does IRIS has any Internal Cloud Storage which can be used for managing and Storing  Database Operations. If yes, How can we configure it,

I am trying to setup our first SSL/TLS configuration so we can possibly connect to the EMR FHIR server to pull data into the Interoperability engine.

I am running on Red Hat, and created and submitted a openssl CSR request to our Windows ADCS system.

I used the following command to generate the key and CSR request to submit to Windows ADCS

openssl req -new -sha512 -nodes -newkey rsa:4096 -keyout xxxxxxx.key -out xxxxxxxx.csr

When the certificate was generated I was able to download the individual certificate (cer) and the certificate chain (p7b) in  DER or Base64.

This is a bit of an IRIS question but also and OAuth 2.0 questions:

I am using %OAuth2.JWT.JWTToObject() to "validate" a JWT.  My questions:

- While I am checking claims with the returned body, does the return status of the method "count" as a validation step? In other words, if I weren't checking claims and $$$OK was returned from that method call (passing in the token and public keys), I could feel confident that this token came from the expected auth server?

When manually coding REST services and using GET /api/mgmnt/v1/:namespace/spec/:application/ to return an OpenAPI spec, how do you specify supported properties (OpenAPI Properties in Use | Creating REST Services | InterSystems IRIS Data Platform 2021.1) like responses, definitions, and information in paths like summary and description?

GET /api/mgmnt/v1/:namespace/spec/:application/ | Creating REST Services | InterSystems IRIS Data Platform 2022.2

Using a very basic manual REST service that returns a JSON string I get a pretty basic spec that is not really helpful when it comes to documentation.

I have the following setup: REST broker calls inProc BO via BS. As BO initialization is time-consuming, I want to reuse the same BO during the CSP process lifetime.

I have tried the following approaches:

1. Set %session.Preserve to 1 (I would prefer not to use it as the BO object is not linked to a specific client)
2. Set $$$EnsInProcPersist to 1 (looked relevant)
3. Cached BS between calls

However, every time I call my REST endpoint, I get a new BO. Is there a way to cache inProc BOs in the CSP context?

To run the sample, import it into any interoperability-enabled namespace, start in.

Hi InterSystems Community

We recently had an issue where we weren't able to parse a JSON HTTP request, but the issue went by unnoticed. We also did not have a trace of what the raw HTTP request was that we couldn't parse. I'm looking at improving our this by:
Tracing the raw request using $$$TRACE

Raising an alert which will hit our Ens.Alert router which will compose and send an email

I'm having an issue with consistently raising the alert (I've seen it raise an alert before, and then it wouldn't raise it again on a subsequent message), and also the error back does not really make sense.

The InterSystems documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl… says: "If you do not already have these files, contact the InterSystems Worldwide Response Center (WRC) for download information."

Hibernate is the most used framework to do database persistence. All databases in the market allows get hibernate driver in public repositories, InterSystems no. It is a barrier to InterSystems adoption in the Java Community.

When InterSystems will provide Hibernate jar file to public download, into a public maven repository? 

Any news about JDBC driver and Hibernate dialect on a public java repository, like mvnrepository? Today I need to download the jdbc driver and hibernate jar, add as an external resource on my maven config file to works.

Good morning!

I am developing a Java project (Spring Boot + Maven + Hibernate) but I've a big issue when I try to define the Hibernate Dialect org.hibernate.dialect.InterSystemsIRISDialect... that dialect is neither in the Hibernate library nor in the IRISDriver class com.intersystems.jdbc

How should I define the IRISDialect in my project?

Thank you in advance!

I am hoping someone can let me know if I've gone down a dark path or not:

• I'm using the record mapper to create a business service that waits for a .txt file and sets pipe delimited data to the mapper's record class
• That record (essentially the raw data) is sent to a business process 
  • OnRequest() is implemented where it opens or creates an instance of the target object and validates and transforms and sets the data to the target object as needed; the response is that target object.

InterSystems announces its sixth preview, as part of the developer preview program for the 2023.2 release.  This release will include InterSystems IRIS and InterSystems IRIS for Health.

Highlights

Many updates and enhancements have been added in 2023.2 and there are also brand-new capabilities, such as Time-Aware Modeling, and enhancements of Foreign Tables (but still as an experimental feature). Note that some of these features or improvements may not be available in this current developer preview.

Another important topic is the removal of the Private Web Server (PWS) from the installers.

Hi all,

 I'd like to start playing around with some simple Angular app with IRIS REST Api but I'd like to do so in the best way possible, did you have any best practices and/or VSCode setup to make life easier? 

Keep in mind I've never developed an Angular APP before, so also some simple example will be really useful.

Tnx.

I have created a global say ^myglobal and entered some data. I am storing the name of global in databases and fetching the name based on some criteria. I am getting "^myglobal" in return from databases but i am not able to fetch the data I stored in the global. 

I tried set var = result.global which gives me "^myglobal" in var. Doing WRITE var will return "^myglobal" and not the data i stored in this global.

It can sometimes be useful to list or export all of the subclasses that are derived, directly or indirectly, from a given class. In Studio, the Class -> Derived Classes menu option will show such a list, but I'm not aware of a built-in API for programmatically exporting their source code.

Yesterday I wrote some code for exporting derived classes, and I'm thinking about cleaning it up and putting it on Open Exchange. But if there's a simple way to do this that someone has already figured out, I'd be happy to know about that (and help others find that solution) rather than reinventing the wheel.
