Free Database Space by SwaggerTools

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

Besides the graphic, you also get concrete numbers freshly collected from your local
instance or from remote instances that also installed the package. 

The final result

The processing steps 

  • A CSP page is called by its URL
  • In method OnPreHTTP
    • The System Query fills the temp table from %SYS
    • If the correct URL parameter is provided 
    • ?SERVER=IP-Address[:SuperServerPort[:Username[:Password]]]
    • Actual data are fetched from this server using the Native API for ObjectScript

[Video] Advanced SQL join table cardinality estimates

Hey Community!

We're happy to share a new video from our InterSystems Developers YouTube:

⏯  Advanced SQL join table cardinality estimates @ Ready 2025

Thomas Henchel presents his team’s recent work on improving cardinality estimates in SQL query optimizers - a key factor that affects join ordering and query performance. The team implemented a new state-of-the-art estimation method based on 2023 research. When tested on benchmark queries, most results showed no change, but around 21% of queries ran slower and only about 11% improved. These mixed results highlight challenges in balancing over- and underestimation. The group continues refining optimization techniques to achieve faster, more efficient queries and invites feedback on patterns or concerns from real workloads.

🗣 Presenter: @Thomas Hentschel, Systems Developer, InterSystems

Enjoy watching, and subscribe for more videos! 👍

Empêcher le rollback de données de tables spécifiques

Rubrique FAQ InterSystems

Certaines données, telles que les données du journal d'exécution, ne doivent pas être restaurées à leur état antérieur, même en cas de restauration lors d'une transaction. Pour ce faire, placez ces données dans la base de données IRISTEMP, qui ne sera pas restaurée.

Temporary Globals and the IRISTEMP Databas

En mappant les entités de table à conserver à cette base de données, vous pouvez conserver les informations après le rollback. Cependant, le contenu de cette base de données sera effacé au redémarrage d'IRIS. Si vous souhaitez le conserver définitivement, vous devrez le copier dans une table permanente (après un rollback, etc.). Vous pouvez également rendre une opération de table non transactionnelle en arrêtant la journalisation du processus avant l'opération, puis en la relançant une fois l'opération terminée. Cependant, cette méthode n'est pas compatible avec la mise en miroir.
