What is ASH?

ASH could refer to several different technologies or concepts, making it difficult to provide a single, definitive explanation without more context. Here are a few possibilities: 1. **Oracle Active Session History (ASH):** This is a performance monitoring and diagnostic feature in Oracle databases. It samples active database sessions and stores the data in memory, which can then be analyzed to identify performance bottlenecks. 2. **Adobe AIR Shared Object Helper (ASH):** In the context of Adobe AIR development, ASH could refer to a helper library or tool for managing shared objects (persistent data storage). 3. **Apple System Health (ASH):** Though less common, ASH could allude to a component within Apple's ecosystem relating to system monitoring or health management, though this is a less frequently used acronym. 4. **Abstract Syntax and Semantics for HTML (ASH):** This is a much older reference and less likely to be current. It related to defining formal semantics for HTML. Without further context, it's difficult to determine the specific meaning of "ASH". You'd need to clarify which domain or field you're interested in.
