9 Hybrid Columnar Compression Overview Compression Unit 10x to 15x Storage Reduction Hybrid Columnar Compressed Tables New Approach to Compress Database Tables and Partitions Compressed Tables Can Still be Modified using Conventional DML Operations, such as INSERT and UPDATE Useful for Data that is Bulk Loaded and Queried Update Activity is Light (Archive) How it Works Tables are Organized into Compression Units (CUs) Compression Units are Larger than Database Blocks Within Compression Unit, Data is Organized by Column Instead of by Row Column Organization Brings Similar Values Close Together, Enhancing Compression Copyright 2014, Oracle and/or its affiliates.

10 Heat Map Heat Map gives you a detailed view of how your data is being accessed, and how access patterns are changing over time Programmatic access to Heat Map data is available through a set of PL/SQL table functions, as well as through data dictionary views Data modification times are tracked at the row level and aggregated to the block level Modification times, full table scan times, and index lookup times are tracked at the segment level Copyright 2014, Oracle and/or its affiliates.

24 Setting cpu_count: Partition Approach to Manage CPU Partition CPUs among the database instances 32 cpu_count settings sum(cpu_counts) <= # cpu threads 28 Partitioning provides maximum isolation No CPU contention between instances But if one instance is idle, its CPU allocation is unused Best for performance-critical databases Instance D: 4 CPUs Instance C: 4 CPUs Instance B: 8 CPUs Number of CPUs 4 Instance A: 8 CPUs 0 Copyright 2014, Oracle and/or its affiliates. All rights reserved. Public 27

25 Setting cpu_count: Over-Subscribe Approach Over-subscribe the CPUs among the database instances 32 cpu_count settings sum(cpu_counts) <= 3 x # cpu threads Monitor CPU utilization to see if there s room! Over-subscribing provides efficient CPU utilization Instance D: 8 CPUs Instance C: 8 CPUs Number of CPUs Some contention for CPU if databases are sufficiently loaded 12 Instance B: 8 CPUs Contention is controlled, so system is still stable Best for non-critical databases Instance A: 8 CPUs Copyright 2014, Oracle and/or its affiliates.

26 Instance Caging to CDB Resource Plans Pre-12c: databases managed with Instance Caging 12c: PDBs managed with CDB Resource Plans To convert from Instance Caging to CDB Resource plans Use cpu_count as PDB s share Use cpu_count / num_cpus as PDB s utilization limit (optional!)
