  20. Dynamic ClustersSimplified Configuration with Scalability and Elasticity Simplified Operations for Cluster Scale Out Simplified Initial Cluster Configuration Dynamic Cluster 1 Dynamic Cluster 1 Server Template Server Template Server 2 Server 2 Server 1 Server 1 Server 4 Server 3 Server 6 Server 5 Elastic scaling for Cloud Environments Server 8 Server 7

  21. Dynamic ClustersScale Clusters by Changing one Parameter How it works Create cluster with dynamic servers based on server template Servers inherit attributes from template Rules for calculating server-specific attributes Server name, listen ports, machines….. “N” servers available in the configuration Configuration changes are dynamic Start /stop servers to scale cluster Supported with Console, WLST, Enterprise Manager Elastic JMS (not WSM, ASM, UOO, UOW, SAF) Managed Coherence Servers Dynamic Cluster 1 Server Template Server 2 Server 1 Server 4 Server 3 Server 6 Server 5 Server 8 Server 7 Scale to “N” Managed Servers

  22. Coherence Managed Servers WebLogic Domain/Coherence Containers Machine Node Manager • Streamlined development and management environment for distributed applications • Introduces the Grid Archive (GAR) • Follows the Java EE model • Consolidates configuration into a single distributable entity • Provides Application Isolation & Lifecycle Events • Leverages WebLogic infrastructure to provide: • A Coherence container similar to EJB, JMS and JCA • Management through Configuration Wizard, WebLogic admin console, WLST, JMX, FMWC • Deployment of Coherence applications (GARs) • Node Manager for lifecycle management • Release and install Coherence libraries on the system classpath (no need to package in your application) • Coherence remains available “standalone” Admin Server Machine Machine Node Manager Node Manager Java EE/Coh Server Java EE/Coh Server Cluster Standalone Coherence Clusters Coherence Server Coherence Server Cluster

  23. Enterprise Manager Cloud ControlMoving to Staging & Production

  24. Considerations for Production Environments • Managing WebLogic Server performance & availability • Across the enterprise • Across multiple domains • Enterprise Java Application performance & availability • Business transactions span shared components / services • Deployed across several tiers in different containers • Control over changes that • Affect application availability • May not be authorized • Lead to compliance & security concerns • Administrative tasks to patch, clone & scale up that are • Time consuming • Error prone

  25. WebLogic Management via Enterprise Manager • Performance Monitoring and Diagnostics • Manage across multiple domains • Improve performance and availability of Java EE and web service applications • Diagnose performance problems across tiers • Trace business transactions in the context of the payload • Configuration Management • Track and maintain configurations • Minimize/eliminate downtime due to infrastructure changes • Comply with security and compliance standards • Lifecycle Management • Automate time consuming, manual installation, patching, disaster recovery, and configuration process • Middleware and Java as a Service • Streamline communication with support when encountering bugs Reduce IT operational cost and improve Quality of Service

  26. Centralized Mgmt & Out-of-box Monitoring Monitor all applications, all domains, multiple versions from one console • Manage multiple domains centrally • Monitoring spans: • Clusters and servers • Applications (servlets, JSPs, EJBs) • Hosts • Resources (JVM threads, JDBC connection pool, JMS, data sources) • Predefined metrics • Performance and availability • Real-time monitoring • Historical monitoring for trending and reporting

  27. Routing Topology Viewer • Predefined, graphical topology of middle-tier environment • Understand routing details (e.g. Web Cache to OHS to WLS to data source) • Assess overall health across domain • Search/filter topology • Overlay performance data • Context sensitive menus via right-mouse click on nodes • Print as .PNG file Identify potential performance problems impact across tiers

  28. Log Viewer • Access WebLogic and Fusion Middleware log files from single console • Search and correlate messages across log files based on time, severity or Execution Context ID (ECID) • Download log files or export messages to file Gain access to log files regardless of where they reside

  29. JVM Diagnostics Diagnosing Java apps in production with 24x7 visibility • Always on, real-time and historical monitoring and diagnostics • No application instrumentation or server restarts required • Complete visibility into the JVM stack heap and threads • Analyze impact bi-directionally JVM to DB, DB to JVM • Deploy on any JVM (i.e. Sun, JRockit, IBM) • Accelerate production JVM diagnostics with minimal impact

  30. Enhanced Configuration Comparison for WLS • Find configuration data across domains more efficiently • Support for comparing WebLogic Domains • Predefined, customizable configuration compare template • Ignore expected differences • Receive email when differences detected • Save output of compare in printable, data-centric format • Provision and synchronize configurations via Application Configuration Console • Understand differences across environments quickly

  31. Deploy/Rollback Java EE Applications • Control roll-outs and reduce need for multiple administration consoles • New deployment procedure automates deploying, redeploying, rolling back application(s) to/from domain(s) • Include archive, deployment plan, pre/post deployment scripts, additional files as part of operation • Specify staging mode, start mode, whether to deploy archive as library • WLS domain provisioning also available for complete domains • Reduce need for multiple administration consoles

  32. Patching Oracle WebLogic Server • Automate application of patches across managed servers • Search for and download WebLogic Server patches available on My Oracle Support • Automate applying one-off patches and critical patch updates across domain via Patch Plan • Eliminate downtime by applying patches in rolling mode (parallel mode also supported) • Rollback already applied patches in cases where new problems occur • Automate application of patches across managed servers

  33. Automate Disaster Recovery Operations • Primary and standby sites represented as Generic System targets • Supports stopping and starting a site, Switchover, and Failover operations • Automatic pre-check performed prior to any operation • Operations initiated via EM Command Line Interface (EMCLI) • Track progress of Switchover or Failover operations via Cloud Control console • Available with EM12c Bundle Patch 1 and 12.1.0.2 Plug-in Update • Ensure high availability as well as data protection

  34. Java PaaS “Middleware” as a Service • Self-service deployment of Java apps • Underlying runtime/container delivered as a platform • Enables developers to focus on building and deploying application logic • Chargeback based on application usage and WebLogic configuration • Self-service application lifecycle • Start, stop, monitor, scale-out • Consistent with Oracle Cloud implementation

  35. Wrap-Up

  36. Summary • Automation and standardization are important at all stages • Management tools in WebLogic and Cloud Control complement each other: automation and standardization in the platform and across the data center • Combination of tools in WebLogic and Cloud Control offer full functionality from development to production
