Or, this way?

The Grid VisionHave minimal number of LARGE DatabasesUse Grid Computing

– Clustering ++– Low Cost Components– Higher Quality of Service

Have Business Intelligence (BI) next to Operational Data– Less number of moving parts– Faster processing– Faster Business Intelligence

Use Web Applications– Browser based access– Management of the applications in the data center. No

Grid Computing

Grid computing treats computing as a utility.– Consumers don’t care where computing

occurs.– Producers ensure computational power is:

Oracle Enterprise Manager 10g: Grid Control

Oracle Enterprise Manager 10g Grid Controlprovides the framework for monitoring andadministering the grid, including the following:– A comprehensive overview of the grid’s status– A single point of monitoring for all associated

targets– Alerts with drill-down capability to identify

trouble spots– ASLM to enable holistic management of

application performance

Viewing a List of Hosts in Your GridFrom the Hosts target page you can quicklycheck the status of all host servers in your grid.

Host Home PageThe Host home page allows you to quicklydetermine the state of the host.

Viewing Performance InformationThe Host Performance page shows you howthe host is using its available resources.

Comparing Metrics ofMultiple Database TargetsThe Database Targets page makes it easy tocompare resource usage of different databases.

Database Home PageThe Database Home page presents an overview ofdatabase status and resource consumption.

Monitoring Grid Control

Grid Control must be functioning efficientlyto effectively monitor targets. Whenmonitoring the Grid Control framework, youshould:– Examine management repository operations– Ensure that management services are

functioning properly– Check management agent performance

Application Service LevelManagement (ASLM)

With Application Service LevelManagement (ASLM), you can:

– Manage application availability– Monitor application performance– Diagnose application response-time

issues

Manage Systems HolisticallyAdminister the grid holistically with ASLM:

– Monitor the end user’s view of an application– Correlate performance issues between all components

of an application– Trace transactions and URLs through the entire stack

rather than in only a single component

BeaconsMonitor availability from your key usercommunities:

Define AvailabilityDefine application availability based on a keybusiness transaction that is tested from criticalend-user communities:

Diagnose PerformanceProblems

Interactive transaction trace:– Trace transactions on demand– Find transaction performance bottlenecks

quicklyMiddle-tier performance drilldowns:

– Evaluate historical J2EE activity breakouts– Click to drill down to EJB and SQL levels– Correlate performance
