InterSystems FAQ rubric

Temporary globals stored in the IRISTEMP/CACHETEMP databases are used when a process does not need to store data indefinitely, but requires the powerful performance of globals. The IRISTEMP/CACHETEMP databases are not journaled, so using temporary globals does not create journal files.

The system uses the IRISTEMP/CACHETEMP databases for temporary storage and are available to users for the same.

Hi Community,

Watch this short exercise in writing basic code snippets in InterSystems ObjectScript using Copilot in VSCode and the GPT-4.0 engine. This screencast covers "Hello, World," global manipulation, class creation, and building a simple REST API application.

I have the class ConfigUtils.ConfigSettingsTable, which is a persistent object. I know I need to map packages from the original namespace. In this case, I have mapped ConfigUtils.ConfigSettingsTable from the originating namespace (IRISTST database) across all other namespaces.

Parallel query hinting boosts certain query performances on multi-processor systems via parallel processing. The SQL optimizer determines when this is beneficial. On single-processor systems, this hint has no effect.

Parallel processing can be managed by:

1. Setting the auto parallel option system-wide.
2. Using the %PARALLEL keyword in the FROM clause of specific queries.

%PARALLEL is ignored when it applied to:

InterSystems has released new point updates to resolve a defect affecting the most recent prior versions of 2025.1.0, 2024.1.4, 2023.1.6, and 2022.1.7, for the following supported product lines:

Hello Community,

Is it possible to track or determine where the global variable was set (routine or class) in a form of like label+offset^routine?

Hey everyone,

I'm diving deeper into Caché ObjectScript and would love to open a discussion around the most useful tips, tricks, and best practices you’ve learned or discovered while working with it.

Whether you're an experienced developer or just getting started, ObjectScript has its own set of quirks and powerful features—some well-documented, others hidden gems. I’m looking to compile a helpful set of ideas from the community.

Some areas I’m especially interested in:

Hello Community,

When I run the following code with x undefined in terminal, it throws a syntax error and returns control to the program stack. After issuing a GO command, execution continues, and setting the global variable ^zz1.

When using standard SQL or the object layer in InterSystems IRIS, metadata consistency is usually maintained through built-in validation and type enforcement. However, legacy systems that bypass these layers—directly accessing globals—can introduce subtle and serious inconsistencies.
