4 Oracle Quality of Service Management - The Objective In real-time you need to be confident that: When resources across the datacenter are sufficient they are continuously deployed to ensure performance and availability objectives will be met. When resources are insufficient to meet demand more business critical objectives will be met at the expense of less critical ones. When load conditions severely exceed capacity, resources remain available. 4 Copyright 2013, Oracle and/or its affiliates. All rights

9 Oracle Clusterware Server Pools Dynamically manage DB resources for services by Policy Control availability with Min, Max, & Importance attributes Easily Manage large clusters consolidating databases 9 Copyright 2013, Oracle and/or its affiliates. All rights

10 Performance Classes Performance Classes are a group of work requests whose service levels are to be managed. Work Requests are defined by Performance Classifiers containing the DB Service Name and optionally session parameters Initial set of Performance Classifiers are automatically discovered and created from CRS-managed services Performance Objectives are defined on Performance Classes by Policy 10 Copyright 2013, Oracle and/or its affiliates. All rights

11 Performance Policies Policies are named sets of Performance Objectives and Server Pool Overrides to meet Business Objectives Performance Classes can be ranked for their criticality to maintain their performance objectives. Server Pool properties Min, Max and Importance can be overridden to assure resource availability. Only one policy is active at any time. 11 Copyright 2013, Oracle and/or its affiliates. All rights

12 Performance Objectives Performance Objectives can derive from your SLAs. Performance Objective for Database 11gR2 is Average Response Time per database request. Performance Objectives made comparable through the new Performance Satisfaction Metric (PSM) PSM quickly shows how well you are doing against your objective 100% -100% 12 Copyright 2013, Oracle and/or its affiliates.

15 Which Resources Does QoS Manage? - CPU Resources targeting OLTP workload demand surges Manages CPU shares per Performance Class Will recommend increasing CPU shares for target PC Will recommend decreasing CPU shares of competing PC Enables schema-based consolidation within a single database Manages current CPUs per slice (DB) per server Will recommend increasing CPU_COUNT for target slice Enables database consolidation per server pool Manages current sizes of Server Pools Will recommend moving servers between pools Enables database consolidation within a single cluster 15 Copyright 2013, Oracle and/or its affiliates.

16 Integrated Memory Guard Protects Resources Receives a stream of OS Memory metrics from CHM Analyses once a minute for over-committed memory conditions Free Memory(including caches) Swap used < 0 Clusters need to pass CVU swap check to receive benefit Issues alert should any server be at risk Protects existing work and applications by automatically closing the server to new connections Stops all CRS-managed services transactionally on the server Automatically re-opens server to connections once the memory pressure has subsided Starts up all CRS-managed services that are not disabled 16 Copyright 2013, Oracle and/or its affiliates.
