Your AI agent needs a Data Constitution, not just better prompts
The article discusses the evolution of Artificial Intelligence towards Agentic AI, which are autonomous agents that can perform complex tasks. However, it highlights the fragility of these agents when they utilize poor-quality data from sources like flat files or vector databases. To enhance reliability, a “Data Constitution” is necessary, ensuring data integrity through a structured…

23c – Simplified PDB hot cloning in a Physical Dataguard environment
In one of the previous articles I superficially mentioned a relevant limitation in the combination of Multitenant + Dataguard in 19c: It simply cannot execute a synchronized hot cloning (primary cloning cascading to the standby). Today we are going to address that issue in detail, and we will discover an important improvement that we find…

23c – Floating PDBs – The Lab
The main objective of this laboratory is to understand the behavior of PDBs (Pluggable Databases) and services based on their configuration, particularly focusing on a “floating PDBs” configuration. We are interested in observing if the clusterware properly distributes the PDBs and their services during startup, verifying the behavior in case of a node failure in…
