I have a CSP page in the a namespace(UTIL) that calls a class which lives in a different namespace (DEV). I’ve set up the appropriate global/package mapping in UTIL so the class can be accessed.
I am creating a class to validate JSON body of requests. When I use the method %ValidateObject to check errors in the object, if I define some properties with %DynamicObject or %DynamicArray and use the Required parameter, this method does not work, it ignores validation, only works with properties %String, %Integer etc.
$System.Util.GetEnviron("USERPROFILE") returns "C:\WINDOWS\system32\config\systemprofile". I don't know what that is, but that folder doesn't even exist. The correct value which I need is "C:\Users\robert.steed", as seen via the Windows command line "set" command.
Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)
NAMING THINGS RANDOMLY
We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare.
In the modern world, the most valuable asset for companies is their data. Everything from business processes and applications to transactions is based on data which defines the success of the organization's operations, analysis, and decisions. In this scenario, the data structures need to be ready for frequent changes, yet in a managed and governed way. Otherwise, we will inevitably lose money, time, and quality of corporate solutions.
Can I please check if anyone has built a simple web interface for maintaining custom SQL lookup class.
We have a simple persistent class in HealthShare which is used for storing Pathology test codes. Test codes in this lookup class is used for message filtering and applying additional logic when processing pathology results/orders.
If you are in the business of building a robust High Availability, Disaster Recovery or Stamping multiple environments rapidly and in a consistent manner Karmada may just be the engine powering your Cloning Facility.
Being impressed by the graphics of the package GBLSizeMonitor from @Ashok Kumar T I ask for his help, and this is the result of our cooperation. As in the previous package, all is running from a CSP page. And it is all classic CSP written with InterSystems ObjectScript, JavaScript, HTML
Surely you wanted to use the OpenAPI Specification (OAS) JSON you used for your spec class on the iris-web-swagger-ui iris package. The generated OAS from the ##class(%REST.API).GetWebRESTApplication(...) method is very crude, with no description on the parameters or the expected response structure.
So after creating your REST application from an OAS you should have:
Hello and welcome to the Developer Ecosystem News!
The third quarter of the year was full of exciting activities in the InterSystems Developer Ecosystem. In case you missed something, we've prepared a selection of the hottest news and topics for you to catch up on!
We’re updating the Developer Community search engine this weekend to make it faster and more accurate (we hope 😉).
During the update, you may experience occasional slowness or brief interruptions in search performance. If you notice anything unusual or run into issues, please let us know in the comments below - your feedback helps us ensure everything runs smoothly.
In my DB, it has more than 10,000 files. I tried to search for a particular file (mac), but there is no search option to find it. Can you help me find that option to search for a file?

This web interface is designed to facilitate the management of Data Lookup Tables via a user-friendly web page. It is particularly useful when your lookup table values are large, dynamic, and frequently changing. By granting end-users controlled access to this web interface (read, write, and delete permissions limited to this page), they can efficiently manage lookup table data according to their needs.
The data managed through this interface can be seamlessly utilized in HealthConnect rules or data transformations, eliminating the need for constant manual monitoring and management of the lookup tables and thereby saving significant time.
Note: If the standard Data Lookup Table does not meet your mapping requirements, you can create a custom table and adapt this web interface along with its supporting class with minimal modifications. Sample class code is available upon request.
The built-in task manager is limited. How can I implement a robust, distributed job scheduler in IRIS with support for dependencies, CRON syntax, and failover recovery?
We run mixed workloads in IRIS. For analytical queries, are bitmap indexes effective? What are the caveats for concurrent OLTP updates, and how should I maintain bitmap indexes efficiently?
We require user-specific row access (row-level security). How can we enforce this in SQL and ObjectScript using custom class parameters and dynamic WHERE clause injections?
When writing dynamic SQL queries using embedded SQL, how can I force or ensure that filter conditions are pushed down to the data access layer rather than evaluated in memory?
I have large joins involving millions of rows. How can I profile and tune the SQL engine’s parallel execution? Are there EXPLAIN plan features to inspect threading and task distribution?
We want to expose both REST and GraphQL endpoints over the same data models. Is there a way to implement or integrate GraphQL with ObjectScript and map to class methods?
We’re encountering occasional deadlocks when accessing persistent objects. How can I trace lock acquisition and identify cyclic dependencies in real time?
What are the best practices for creating a multi-tenant app in IRIS? How can I isolate data per tenant using namespaces, control resource usage, and delegate access via roles securely?
We're encountering occasional deadlocks in a mirrored IRIS deployment. How can we track down which global or object write caused the lock cycle, and how does IRIS mirror lock propagation internally?
We want to iterate over large global structures in real-time without blocking or locking readers. How can we safely use $Order() and implement a lock-free analytics approach?
We need to authenticate users via Azure AD or Okta. What are the best practices to implement federated authentication using OAuth2/OIDC or SAML in IRIS Management Portal or custom web apps?
We are using IRIS with a sharded architecture. Complex SQL queries (with joins, aggregates, and subqueries) are performing slowly. How can I design queries or indexes to optimize distributed execution across shards?
