6 Middleware Application servers (i.e., middleware) reside between the frontend and the backend The mostly (but not always) host and execute web application code and web services Oracle WebLogic Server is one such application server Raastech, Inc All rights reserved. Slide 6 of 58

7 Introducing Oracle WebLogic Server Obtained through acquisition of BEA Systems in 2008 Latest version is Oracle WebLogic Server 12c (12.1.3) Industry s best Java EE application server Oracle marketing stuff: New features for lowering cost of operations, improving performance, enhancing scalability Provides flexibility between on-premise and third-party clouds Increases developer productivity with mobile application development and maven support Optimized for Oracle Exalogic Elastic Cloud Provides extreme cloud performance, scalability, and elasticity, unmatched integration with Oracle s Database 12c including multi-tenant database support Raastech, Inc All rights reserved.

8 WebLogic Server: Foundation for Fusion Middleware WebLogic Server is the core foundation of all Oracle Fusion Middleware products (and applications) OEM Grid Control OBIEE Access Manager SOA Suite WebCenter Portal Data Integrator Oracle WebLogic Server Clustering JNDI Resource Adapters JDBC Security Self Tuning Raastech, Inc All rights reserved. Slide 8 of 58

9 Monitoring versus Management Monitoring involves being aware of the state of the system View real-time state of the environment Obtain historical metrics for analysis purposes Receive notification and alerts Management involves the ability to take action somehow Turn on/off services and components Modify configuration settings Execute jobs (e.g., purge, backup, queues, etc.) Issue a garbage collection Raastech, Inc All rights reserved. Slide 9 of 58

10 Key Areas of Monitoring and Administration We want to monitor/administer key areas in WebLogic Server, such as: Managed servers Persistent stores JMS servers JMS destinations (i.e., queues, topics) Work managed (i.e., threads) Java applications Clusters Data sources and connection pools Security realms (i.e., users) Logs Raastech, Inc All rights reserved. Slide 10 of 58

13 WebLogic Server Administration Console Indispensable All administration performaned through here View real-time state of environment Does not have to be running for your applications to run, but highly recommend Raastech, Inc All rights reserved. Slide 13 of 58

14 DMS Spy Servlet The DMS Spy Servlet is available with WebLogic Server Provides real-time metrics of your environments at this URL: Can be invoked via command line as well for scripting purposes Raastech, Inc All rights reserved. Slide 14 of 58

16 Oracle Enterprise Manager Cloud Control OEM Cloud Control 12c is the ideal tool for monitoring WebLogic Server (as well as your entire infrastructure) Perform administration, schedule jobs, correlate events, receive triggered alerts, and much, much more Be prepared to spend some money on this Raastech, Inc All rights reserved. Slide 16 of 58

20 VMware vfabric Hyperic Was a decent monitoring tool, though less comprehensive than OEM Very cost effective (at least before VMware acquired them) Many other 3 rd party tools on the market exist as well (e.g., AppDynamics, etc.) * We are not endorsing any product over another; just merely demonstrating the availability of 3 rd party monitoring tools Raastech, Inc All rights reserved. Slide 20 of 58

27 Agents All monitoring tools require an agent to be installed on the target server Usually employ a push concept Management Server Agent Agent Agent Agent Target Target Target Target Advantages Agents can continue collecting even if there is no connectivity to the management server Powerful features and capabilities can be built into the agents Disadvantages Becomes painful if trying to install / upgrade hundreds or thousands of agents Raastech, Inc All rights reserved. Slide 27 of 58

29 WLST (WebLogic Scripting Tool) WLST is WebLogic Servers s preferred scripting language Common among administrators from a BEA background WebLogic Server centric Uses Jython (which allows Python scripts to be executed) Scripts can be developed cross-platform, requiring little to no changes Example of starting up a managed server using WLST: $WL_HOME/common/bin/wlst.sh wls:/offline> connect('weblogic', 'welcome1', 't3://adminhost:7001') wls:/soa_domain/serverconfig> start('soa_server1', 'Server') Raastech, Inc All rights reserved.

33 WebLogic RESTful Management Service Oracle WebLogic Server 11g introduces the RESTful Management Services The monitoring resources are hosted by an internal web application This is a feature that must be enabled It provides access to key metrics easily accessible via REST (i.e., essentially another API into WebLogic Server metrics) They are generally accessible via a URL, for example: Raastech, Inc All rights reserved. Slide 33 of 58

39 Disadvantages of the RESTful Management Service No historical metrics (only real-time, similar to the DMS Spy Servlet) No administrative capabilities (monitoring only) Limited to the following object types: Servers Clusters Applications Data Sources Raastech, Inc All rights reserved.

41 Remote Monitoring Our definition of remote monitoring: Not-at-your-desk monitoring Could be through: s Web-based console Mobile app Only alerts, but cannot view adhoc Difficult if VPN access required first Ideal scenario Raastech, Inc All rights reserved. Slide 41 of 58

42 Remote Management Our definition of remote management: Issue commands when away from your desk Could be through: Parsed replies Web-based console Mobile app Was cool back in 2004 Difficult if VPN access required first Ideal scenario Raastech, Inc All rights reserved. Slide 42 of 58

44 Raastech Mobile Manager Raastech Mobile Manager for Oracle Fusion Middleware Developed by Raastech Beta launch in October 2015 The world s only mobile monitoring and management solution for Oracle Fusion Middleware Raastech, Inc All rights reserved. Slide 44 of 58

46 Designed with UX and CX in Mind Emphasis placed on usability Extremely responsive UI, even when viewing huge data sets Focuses on top 20% core features Management requests are instantaneous Can literally get up and running within minutes Raastech, Inc All rights reserved. Slide 46 of 58

48 Remote Management Runs on GlassFish Server or WebLogic Server, with a backend MySQL database Relies on cloud service for notifications The 3 components are: Raastech Mobile Manager Raastech Management Server Raastech Notification Server Raastech, Inc All rights reserved. Slide 48 of 58

49 Customizable Views Display data as: Raw Percent bar Line graph Time bar Framework allows the ability to dynamically add additional metrics to monitor Raastech, Inc All rights reserved. Slide 49 of 58

51 Agentless Architecture No agent required on target servers Employs a pull concept Intended to simplify provisioning Simply enter host, port, username, and password! Target Management Server Target Target Target Raastech, Inc All rights reserved. Slide 51 of 58

52 Management & Administration Start and stop managed servers Start and stop JMS servers Start and stop data sources Start and stop JMS resources such as topics and queues Dump thread stacks Garbage collect Logs Raastech, Inc All rights reserved. Slide 52 of 58

53 Complete Oracle Fusion Middleware Current: Oracle WebLogic Server Near term: Oracle SOA Suite Oracle Service Bus (OSB) Oracle Business Activity Monitoring (BAM) Oracle Business Intelligence Enterprise Edition (OBIEE) Oracle Data Integrator (ODI) Oracle Access Manager (OAM) Oracle Internet Directory (OID) Future: TBD Raastech, Inc All rights reserved. Slide 53 of 58

56 Summary Monitoring approaches: Console-based Tool-based Custom-based Poor remote monitoring and management options No mobile app solution by any vendor (except for Raastech Mobile Manager), likely due to complexity They re missing the point, the key is to narrow focus to the most widely used areas Raastech, Inc All rights reserved.
