Real Time ADDM - wykład

Real Time ADDM
Real-Time ADDM automatically monitors the database in real time.
Real-Time ADDM proactively detects and diagnoses transient high impact problems
such as these before they threaten application performance:
■ High CPU
■ I/O spikes
■ Memory
■ Interconnect issues
■ Hangs and deadlocks
When Real-Time ADDM detects a possible performance problem, it triggers data
collection. The data is saved in the report repository (part of AWR). When you view a
Real-Time ADDM report from EM Express, an analysis is performed, and findings and
recommendations are made. Because Real-Time ADDM reports are stored in AWR,
they can help you identify recurrences of a problem over time.
