Oracle Database has published two AHF Fix Flow articles and a video, showing how to use AHF to diagnose and resolve ORA-04031 and ORA-07445 errors.

ORA-04031: unable to allocate bytes of shared memory, occurs because more shared memory was needed than was available.

ORA-07445 exception encountered: core dump, can happen anywhere within Oracle code. It’s caused by an operating system exception occurring which should result in the creation of a core file.

Both of these error are frequently seen by Database customers.

The AHF team have created two new Fix Flow articles showing how to use AHF to collect diagnostic collections for either error. Each article explains why the error occurs and gives step-by-step guidance to use AHF to capture a diagnostic collection, then how to use it to either find a resolution or get more help from Oracle Support.

As part of the efforts to provide the most accessible experience to our users, AHF 24.3 introduces the next accessibility features.

Accessibility refers to the design and implementation of digital products and environments that are usable by all people, regardless of their abilities or disabilities. This includes ensuring that people with disabilities can perceive, understand, navigate, and interact with digital content and interfaces effectively.

Accessible Home Button

Revamped Home tab to make it more user-friendly, especially for those using screen readers. Now, it behaves exactly like a tab should, eliminating any confusion caused by its previous behavior as a button.

Enhanced Accessibility within Home Page Regions

Support for screen readers to all items within the Topology and Insights sections in Home page. This means that users relying on screen readers can now easily identify and understand each item they’re focusing on along with the valuable information it provides.

Accessible Navigation in Timeline

Replaced the old pagination component in Timeline it with a sleek new scroll bar, making it easier for you to navigate through content without losing focus. The new scroll bar ensures a seamless browsing experience, specially for the users using screen readers.

Introducing Accordions

Now, within the Best Practice Issues section, you’ll find accordions that act as top-level details for each check. When expanded, these accordions reveal check-related data points, providing you with a clear and organized view of the information you need. This not only preserves the functionality of the previous layout but also eliminates the nested tables pattern, ensuring better accessibility support for all users, including those relying on screen readers. With this update, accessing and understanding your reports has never been easier!
