Agenda  Problems Facing Datacenters  Oracle’s Solution  Management Topology  Features – Daily Administration – Performance Monitoring  Q&A

Problems Facing Datacenters

 Complex environment – Several components to Application Server – Variety of target types (hosts, DBs, apps, network)  No specialized Application Server administrator  No budget for extensive training  Not aware of issues with application performance until trouble ticket is logged  Difficult and time consuming in diagnosing poor performance

Oracle’s Solution

Oracle Enterprise Manager

Management Topology

OracleAS Console  Installs with every OracleAS instance  Version inline with Oracle10 i – 10.0  Unique port and IAS_ADMIN password for each OracleAS Console  Real-time monitoring of single OracleAS instance  “Administration console”  Relies upon OracleAS management stack  DCM  OPMN  DMS

OracleAS 2 OracleAS Console 2 OracleAS 1 OracleAS Console 1 OracleAS Console (cont’d)

Central Console  New with Enterprise Manager V4  Installs from separate CD-ROM from OracleAS software  Version not inline with OracleAS –  Provides consolidated management and monitoring of entire enterprise  Out-of-box monitoring and alert notification  Historical collections for trend analysis  Group Management  Application Performance Management  Drilldown to OracleAS Consoles

Manage from Anywhere New Enterprise Manager v4 Portals HTTP/S OracleAS Console 1 HTTP/S OracleAS Console 2 HTTP/S Central Console Management Repository HTTP/S Firewall Mobile Device Management Service

Features: Administration  Application Server Home Page  Deploying J2EE Applications  Management through Grids  Port Management  Diagnostic Logging  Something re: reassociation  Enterprise Configuration Management  Component Management

Deploying J2EE Applications Consolidated view of J2EE apps across all OC4J instances Configure Java Messaging Services for J2EE apps Only Oracle AQ and third party Configure and monitor Message Driven Beans Configure J2EE data sources easier with new “create-like” feature Improved deployment Wizard More comprehensive error messages

Management through Grids

 Consolidate distributed targets for more effective management – Web Applications – Application Servers – Databases – Hosts  Monitor key performance metrics and alerts for all targets  Drilldown into more details  Quickly isolate and diagnose root cause of problem

Management through Grids (cont’d)  Cluster info – File-based repository supported by DCM – Create file-based repository via command line, not via Oracle10 i AS Console – Perform file-based repository cluster management operations via Oracle10 i AS Console

Port Management

 View port ranges and ports in use across all components  Configure various ports from central location – Access to port dependency info  Port dependencies documented in OracleAS Admin Guide

Diagnostic Logging

 Log Viewer – Access all Oracle10 i AS diagnostic logs from single location  Log Loader – Automatically load log data into a file-based repository for easier investigation – Cross-correlation queries

Something re: reassociation

Reassociation  Ability to reassociate (ie reconfigure) Oracle10 i AS Infrastructure with an application’s mid tier  Types of reassociation – Identity Management – Metadata Repository – DB Managed Cluster  Customer use cases – Disaster recovery (backup & recovery) – Identity Management reconfiguration – Support for application lifecycle (test  stage  production)

Reassociation: Identity Management  Intuitive ‘Change Identity Management Wizard’ to step user through reconfig  Supports reassociation of OID, SSO or both

 Intuitive ‘Change Metadata Repository Wizard’ to step user through reconfig  Configuration performed at DB instance level  For Portal mid tiers, dads.conf file automatically updated with new Metadata Repository Reassociation: Metadata Repository

Reassociation: DB Managed Cluster  Intuitive ‘Change DB Managed Cluster Wizard’ to step user through reconfig  No support for file based clusters

Enterprise Configuration Management

 Automatically gather and store hardware and software configuration data – OS registered software – Hardware resources – Patch levels – Dependencies  Configuration management operations – Locate and download Oracle software patches directly from MetaLink – Search for and compare software installations

Component Management

 HTTP Server  OC4J  Web Cache  BC4J  Discoverer  Forms  CM SDK  Internet Directory  Personalization  Portal*  ProcessConnect*  Reports*  Syndication Server  Ultrasearch  Wireless * Offers key new features

Component Management (cont’d)  Consistency across all Oracle10 i AS components – Common look-and-feel – Consistent level of management  Administration  Monitoring

Central Console Management  Application Server Home Page  Monitoring Oracle10 i AS  Consolidated Group Management  Application Performance Management  Enterprise Configuration Management  Drilldown to Oracle10 i AS Consoles Sites with both Oracle10 i AS and database, like LLNL, thought the Central Console was key to managing their enterprise.

Application Server Home Page Consolidated, at-a-glance view of key Oracle10 i AS information  Availability  J2EE apps  Resource usage  Alerts  Diagnostics  Administration

Features: Monitoring  Out-of-the-Box Monitoring  Historical Collections and Analysis  J2EE Application Diagnostics  Application Performance Management

Out-of-the-Box Monitoring

Monitoring Oracle10 i AS  Monitor Application Server level as well as component level – Real-time performance and availability monitoring – Lights-out monitoring defaults – Historical collections for trend analysis  Out-of-box notifications for critical alerts  Summary view for rapid problem identification  Easily compare performance across Oracle10 i AS instances

Application Performance Management

 Web application “client” experience – Direct measurement of real end-user performance against your web app  Business transaction monitoring – Emulate and monitor client experience from remote locations  Monitor availability of web apps  Monitor performance of application transactions Beta customer Digital River sees APM as the key tool for application management. It’s the first feature they are rolling out in the Central Console.

Application Performance Management (cont’d)  Cross-tier tracing of business transactions – Trace web site transactions through the application server stack  Breakdown of processing time ­HTTP Server ­OC4J container ­Data source
