**The SYSTEM and TEMP tablespace sizes are minimums for Enterprise Manager only repositories. On raw file systems Oracle recommends using more than the minimum size to help prevent space constraint issues. These tablespaces are defined with AUTOEXTEND set to ON by default to help mitigate space constraint issues. The actual size of the MGMT_TABLESPACE could vary widely from deployment to deployment due to variations in target type distribution, user customization, and several other factors. *These are strictly minimum values and are intended as rough guidelines only. Table 13-3 Total Management Repository Storage Deployment Size However, evaluating these trends regularly can be helpful in evaluating any other changes to the deployment. Step five is only required if you intend to grow the deployment size in terms of monitored targets. You must complete steps two, three, and four before you continue on to step five. These steps are essential to an efficient Enterprise Manager Cloud Control site regardless of its size or workload. Steps two, three, and four must be done, regardless of whether you plan to grow your Enterprise Manager Cloud Control site, for the life of the deployment on a regular basis. Step one need only be done once for a given deployment. Periodically evaluate your site's vital signs (detailed later).Įliminate bottlenecks using routine DBA/Enterprise Manager administration housekeeping.Įxtrapolate linearly into the future to plan for future sizing requirements. If you have not already installed Enterprise Manager Cloud Control, choose a rough starting host configuration as listed in Table 13-1. Here are the steps to follow to enact the Enterprise Manager Cloud Control sizing methodology: It also assists in keeping your deployment performing at an optimal level. This information, combined with an established, rough, starting host system size and iterative tuning and maintenance, produces the most effective means of predicting capacity for your Enterprise Manager Cloud Control deployment. The Oracle Enterprise Manager 12 c documentation is available at the following location on the Oracle Technology Network (OTN): Īn accurate predictor of capacity at scale is the actual metric trend information from each individual Enterprise Manager Cloud Control deployment. Oracle Enterprise Manager Grid Control Installation and Basic Configuration The Management Repository - The schema is an Oracle Database that contains all available information about administrators, services, and applications managed within Enterprise Manager.įor more information about the Cloud Control architecture, see the Oracle Enterprise Manager Cloud Control 12c Release 12.1.0.1 documentation: The Management Service - A J2EE Web application that renders the user interface for the Cloud Control console, works with all Management Agents to process monitoring and jobs information, and uses the Management Repository as its data store. The Management Agent is also responsible for communicating that information to the middle-tier Management Service and for managing and maintaining the system and its services. The Management Agent - A process that is deployed on each monitored host and that is responsible for monitoring all services and components on the host. The components of Enterprise Manager Cloud Control include: Each component of Cloud Control can be configured to apply both these concepts. The architecture for Oracle Enterprise Manager Cloud Control exemplifies two key concepts in application performance tuning: distribution and parallelization of processing. Overview of Repository and Sizing Requirements for Fusion Middleware Monitoring Overview of Oracle Enterprise Manager Cloud Control ArchitectureĮnterprise Manager Cloud Control Sizing and Performance Methodology This chapter contains the following sections: Receiving good baseline values for the Enterprise Manager Cloud Control vital signs and setting reasonable warning and critical thresholds on baselines allows Enterprise Manager to monitor itself for you. By maintaining routine housekeeping and monitoring performance regularly, you insure that you will have the required data to make accurate forecasts of future sizing requirements. It can also help you with capacity planning, sizing and maximizing Enterprise Manager performance in a large scale environment. This chapter describes techniques for achieving optimal performance using the Oracle Enterprise Manager application. Oracle Enterprise Manager Cloud Control 12c Release 12.1.0.1 has the ability to scale for hundreds of users and thousands of systems and services on a single Enterprise Manager implementation. 13 Sizing Your Enterprise Manager Deployment
