WAS Support & Monitoring Tools

  1. 1. WAS Support andMonitoring Tools
  2. 2. WAS ND Support for Apple vac• Royal Cyber 24*7 Support for IBM Websphere Application Server – Installation, Migration, A dministrations & Clustering – Performance Monitoring & Troubleshooting – Routine Supports & Deployments – Writing Automation Scripts
  3. 3. Apple vac Websphere Landscape
  4. 4. Apple VacationsWhat were Apple vac Pains? – Response Time – Load Balancing & High Availability in Peak Hours – Connection Timeout – Thread Hang – Class Loader issues – Memory Leak
  5. 5. Tuning Methodology
  6. 6. Royal Cyber Inc brings solutions for all of yours WebSphere Needs • Monitoring WebSphere Server performance • Problems in managing WAS – Connection Timeout problem – Thread Hang problem – Classloading problem – Memory Leak problem – JVM Heap size problem – Managing thread problem settings – And more! • wsadmin scripting • Clustering & Load Balancing for High Availibity
  7. 7. Analysis Tools to find root cause of issue
  8. 8. Troubleshooting server hang issues– WebSphere process hang detection steps– Once a hang is suspected, obtain a thread dump or javacore– For a typical hang, collect three dumps at a few minutes interval– To see if anything is moving within the process (but slowly)– Examine the thread dumps with Thread Analyzer or by hand– Hang detection tools– ThreadMonitor architecture was created to monitor thread pools within– ThreadAnalyzer– GUI-based tool Gathers and analyzes thread dumps from a WebSphere Application Server– Provides recommendations based on analysis

  10. 10. How to troubleshoot crashes• Symptoms• Process terminated with Java exception or native signal Usual causes• Out of memory exception• Call stack overflow• Unexpected exception (for example, out of disk space) Optimizer failure (for example, JiT)• Bad JNI call or library problem• Segmentation violations while executing native code
  11. 11. How to troubleshoot OutOfMemory error?• Java virtual machine error Not enough memory to allocate an object; can be caused by• the following:• The Java heap is too small• Memory is available in the heap, but it is fragmented (for JDK 1.4.2• and earlier)• Memory leak in the Java code• Not enough space in the native memory

  14. 14. Monitoring and Tuning of Thread Pools• IBM Tivoli Performance Viewer is a tool embedded in the administrative console that lets you view the PMI (Performance Monitoring Infrastructure) data associated with almost any server component.• The viewer provides advice to help tune systems for optimal performance and recommends alternatives to inefficient settings.

  22. 22. Step 1) Manage and Monitor the Hardware and Operating Systems IBM Tivoli Monitoring (ITM) I need monitoring for my heterogeneous physical or virtual operating system environments or any custom, home-grown or industry vertical application. Windows Server VMware 1 Citrix IBM AIX  IBM AIX LPAR  IBM AIX DLPAR HP Unix  IBM AIX WPAR SUN Solaris  SUN Containers  SUN Zones Linux Operating Systems  SUSEMonitoring for Operating Systems Includes:  Red Hat  Others . . . . .IBM Tivoli Monitoring (PVU Priced )IBM Tivoli Monitoring for MS Apps Entry ( Per Server Pricing)IBM Tivoli Monitoring Agentless ( Per Server Priced ) 22
  23. 23. Step 2) Manage the Applications (Microsoft Flavour) ITM for Microsoft Applications AdvancedI need a turn-key monitoring solution for my Microsoft Applications and the Microsoft Application infrastructure environments upon which they depend. Microsoft .NET Microsoft Exchange Server  Microsoft Sharepoint  Microsoft Biztalk VMware Citrix Microsoft SQL Microsoft IIS Server Microsoft Active Directory Microsoft Windows  Operating Systems Custom Monitors  Microsoft Hyper-V Microsoft Entry Pricing  Microsoft Clusters23
  24. 24. Step 2b)Non-MS Applications ITCAM for Applications 3-Pack or Full Pack I need a monitoring solution for my heterogeneous Application and Application Infrastructure environments upon which they depend. Messaging Backbone E-mail and Collaboration • WebSphere MQ • Lotus Domino • Message Broker Databases  DB/2 Web Resources  Oracle Operating Systems  WebSphere  Sybase  Virtualized Environments  Apache  Custom Environments VMware Citrix Applications  SAP  Siebel  PeopleSoft1 Included with Operating System or available separately Custom Monitors 1 24
  25. 25. Step 3) Lets drill down and get a better idea of what is going wrong ITCAM for Application Diagnostics I need to specifically understand why the Websphere Application is running slow Know what line of Database Delay ( jitter ) is detected code is the offender so the Development team can fix. Websphere Application End User is having Issue 25

  28. 28. Case StudyChallenge In order to maintain and monitor a large databaseof their clients ,Apple Vacations have to monitortheir system’s response time, protecting systemform any harm and to measures theavailability, performance and content. IBM Tivoli Composite Application Manager helped a busy website to control hardware, software and laborProblem … costs by tracking and improving server utilization Monitoring systems is not available . No alerts, no treatment or consolidation Business Benefits Manual monitoring causing human errors. Lack of IT Change Management leading to error ITCAM directly measures the prone high risk changes. availability, performance and content of these No formal IT processes and lack of tools to services through periodic polling from strategically enforce their execution. distributed Points of Presence.Solution… It produces both real-time alerts on service In order to cope with this problem, Royal Cyber response and Web-based reports of historical suggested a solution IBM Tivoli® Composite service performance, relative to a flexibly definable Application Manager (ITCAM) for Websphere SLA. IBM Tivoli Monitoring (ITM) Complexity reduction of monitoring environment Universal Agent for URL Monitoring Better monitoring information to support root Unix Log Agent for Logs Monitoring cause analysis www.royalcyber.com
