  13. 13. 13 So you say: “I simply use Tomcat”? • Most people use a *lot* more than just Tomcat. What about: • Once you add all of these (and more), how do you make it work together? (i.e. 3rd party CDI wont work with 4th party JTA, etc.) • What is the performance of all of the above with all the JAR scanning going on? • How do you test/manage/secure/debug all of this? • Are you coding to standards? Are you coding your app or building your own Java EE server? • Lack of API support in Tomcat leads to lost development productivity and additional expense for integration and testing REST SOAP JPA WS-* JTA Security JMS CDI Bean validation OSGI JTA EJB WebRTC Batch Concurre ncy Oauth SAML Other Java EE? vs.

  22. 22. 22 Global transactions • Enterprises often have to update data in: • Databases (DB2, Oracle DB, MS SQL, Informix) • TP monitors (CICS, Tuxedo) • Messaging servers (IBM MQ, Tibco EMS, ActiveMQ) • Caching servers (WXS), etc. • What happens if there is a failure during the transaction commit? • Tomcat and tc Server do not include a transaction manager • Only support local transactions (with a single resource) • Without a distributed transaction manager, there is no support for two-phase commit for global transactions, where the scope is across multiple resources • Writing business critical code without global transaction management is possible, but is very complex (i.e. error prone and expensive) • WAS and Liberty support distributed transactions with two-phase commit and automatic data recovery in the event of a network failure, ensuring transaction integrity

  24. 24. 24 Automatic transaction log failover & recovery WAS ND Full Profile provides failover of 2PC transactions • WAS ND can be configured to store transaction logs for each server on shared file system or in the HA RDBMS, which allows all peers to see all logs • When a WAS ND cluster member fails, a peer is elected to recover the Transaction Log from the failed server • In Doubt Transactions from a failed Server are recovered very quickly • Significantly faster and cheaper than hardware clustering (seconds vs. minutes) JBoss, Tomcat and Liberty Profile do not provide similar capabilities, which leads to longer recovery times and more admin labor
  25. 25. 25 JBoss high availability issues • Repeated application redeployments eventually require server restarts due to the memory leak issue (Sun and Open JDK PermGen heap gets full and crashes server) • HTTP servers and JBoss App Server JVMs often need restart after configuration updates • Examples: changing the data source pool size or other settings, changing JMS configuration, re-deploying an EAR multiple times (only WAR hot-deploy works, the EAR hot deploy only works for the first couple of times, then causes out of memory errors and JVM crash), etc. • WAS does not need to be restarted as above updates are dynamic • JON server uses database for configuration and monitoring data (Postgres or Oracle) • The DB must be made HA to avoid SPOF and this requires extra license and hw costs • Ripple restart of application servers in a cluster is not provided. Administrator must manually restart servers in a cluster one by one • Transaction log, JMS queues and topics require manual failover effort in case of server failure • WAS failover is automated and takes seconds • Application deployment causes service interruption • WAS ND solves this by introducing the application versioning and graceful client transfer High availability with JBoss may be difficult to achieve without introducing significant redundancy and admin effort

  32. 32. 32 WAS classic console command assistance Automatic capture of administrative actions and generation of scripts to be replayed later • While administrator performs actions in the admin GUI (start, stop, deploy, create, etc.) all his actions are automatically written as Jython command script for WAS • This script can be customized and executed multiple times thus saving time to create complex administrative actions and reducing the learning curve Liberty, Tomcat and JBoss do not offer comparable capabilities
  33. 33. 33 How do customers really use JBoss EAP in production? • Vast majority of JBoss EAP and WildFly customers are not using clustering • Must tolerate lower quality of services ($$$) and • Red Hat customers are forced to purchase 3rd party management tools, monitoring tools, configuration management tools, performance profilers, etc. • 3rd party tools require license and support payments ($$$) • 3rd party tools are not always in synch with the desired version of JBoss ($$$) • 3rd party vendor viability poses risks ($$$) and • Most JBoss customers invest significant staff time to build home grown scripting frameworks for JBoss management (a combination of shell scripting and generation of JBoss XML files using XSLT, Java or other template mechanism) • Cost to develop, debug, maintain such scripts can be significant ($$$) • New major versions of JBoss (major or minor) are not backwards compatible, causing significant rework of home grown scripts and tools ($$$) • WAS provides needed administrative tools out of the box at no extra cost ”One minute of system downtime can cost an organization anywhere from $2,500 to $10,000 per minute. Using that metric, even 99.9% availability can cost a company $5 million a year” - The Standish Group
  34. 34. 34 IBM Garbage Collection and Memory Visualizer (GCMV) GCMV provides analysis and views of your applications verbose gc output. GCMV uses a powerful statistical analysis engine which provides tuning recommendations in these areas: • Memory Leak Detection • Detect Java heap exhaustion and memory leaks • Detect "native" heap exhaustion and memory leaks • Optimizing garbage collection performance • Analyze output from different gc modes (optthruput, optavgpause, gencon, balanced ) • Compare output from multiple logs – side by side • Determine gc overhead, detect long or frequent gc cycles and causes • Recommend settings to avoid long or frequent gc cycles • Recommend optimum gc policy • Fine tuning of Java heap size • Determine peak and average memory usage • Recommend Java heap settings • Flexible user interface makes it possible to carry out further analysis of the data and to "drill down" into the causes of trends and export of data into .csv or jpeg Oracle Java Mission Control (JMC) is free for development use only. JMC does provide data visualization, but it does not make tuning recommendations, nor does it compare various run results side by side. This is a major usability issue.

  36. 36. 36 IBM WebSphere Performance Tuning Toolkit (PTT) PTT is designed to help users tune the performance of WAS using statistical technology. The toolkit collects performance data and consolidates it into a multidimensional data cube. • Find potential performance problems • PTT shows detailed status of system with easily understood charts and forms. Users can analyze the performance data from various perspectives. • PTT helps to find an error as soon as it occurs - monitor the servlet errors, transaction rollback, transaction timeout, JDBC connection timeout, thread hung, etc. • Accelerate performance tuning process • User can tune many servers in one step in a centralized view by running tuning scripts within the workbench, download or upload performance related settings manually or via script • Health Check • PTT can detect the performance decline and take actions automatically based on predefined rules. Rule engine detects the abnormal symptoms according to user defined rules (with ability to create and edit existing rules) • Operations to facilitate problems determination • PTT can generate thread dump and heap dump for the JVM, enable trace settings, extract the connection pool contents • Report engine • Online and offline analysis and reporting (generate, export and print report) Those using WebLogic, JBoss and Tomcat must spend considerably more effort finding all the right tuning variables. In these products the monitoring data is scattered across multiple locations in the Admin GUIs or worse – only available for custom JMX programs

  38. 38. 38 IBM Monitoring and Diagnostic Tools for Java - Health Center Health Center is a diagnostic tool for monitoring the status of a running JVM. It uses a small amount of processor time and memory, and can open some log and trace files for analysis: • Monitoring a running Java application or recorded activity for offline analysis • Very low performance overhead allows to connect to and monitor a live Java application (or replay recorded activity), such as CPU, environment, IO, gc, locking, threads, memory, method tracing with timings, etc. • Save data from a monitored Java application, then reload the saved data later on, without making a live connection. You can load data from multiple files by loading one file, then appending more files. • Viewing the data collected • Displays the data collected using different views (graphical and tabular) • Triggering dumps • Trigger the JVM to generate System Dumps, Heap Dumps, and Java Dumps • Troubleshooting • The first step in troubleshooting is to view the log files that are produced by the Health Center client and agent. Then read the information provided for some of the common problems that you might encounter. • Performance hints • The Health Center agent has little effect on performance. You can improve the performance of the Health Center client by reducing the amount of data collected or displayed. • You can use the Health Center API to write your own code for manipulating Health Center data

  76. 76. 76 Zero migration by design • Why upgrade? • Gain new APIs in a new Java EE level, stay on a supported version of the Application Server, protect against security vulnerabilities, gain speed by moving to the faster new version of JDK or newer hardware • How easy is it to upgrade? Does it cost a fortune? • Liberty implements Zero Migration by design • There is no migration needed for Liberty configuration - the same server configurations can be used with different versions and service levels • Existing features will not change behavior, new feature ‘versions’ will be added and will contain all updates and changes • Tomcat and tc Server require considerable migration effort • Fresh server install and careful configuration updates and testing are required • No automated upgrade or migration tool is provided • JBoss is not backwards compatible and migration is a pain • Backwards compatibility was broken between JBoss v3.x, v4.x, v5, v6. Each of these releases have been disruptive and changed many properties and configuration files, scripting commands, CLI, Admin UI, APIs, etc. Upgrade path for JBoss is to manually copy configuration files and applications to new installation. • These issues result in increased administration costs when using JBoss because of lost productivity related to unnecessary software development.

  78. 78. 78 Considerations for moving off WAS What do you expect to gain from switching? What is the exact criteria to measure if it was a viable move? Moving applications from WAS to JBoss will involve significant effort and cost, including: • Training for operations team • Migration of operational scripts and documentation • Validate the operational characteristics of JBoss • Building missing functions in JBoss • Purchase additional hardware capacity • Purchase more licenses for JBoss • Security • Additional license costs • Unreliable messaging in JBoss • Lack of dynamic clustering and SLA management in JBoss • There are many other capabilities included with WAS that JBoss does not provide See speaker notes for details
  79. 79. 79 WebSphere Application Server Migration Toolkit • No Charge plugins for Eclipse and RAD Rule sets for multiple source / destination combinations (e.g. WLS->WAS, etc.): (a) The tool scans Java source code, JSP files and deployment descriptors and identifies the changes required (allows for Java upgrade also). (b) The tool scans server configuration files (looking for Datasources, servers, JMS settings, etc.) and generates appropriate Liberty or WAS configuration. In most cases the toolkit is capable of making the application changes itself. After the “scan” and “conversion” are done the toolkit generates report on the results of the migration and any manual migration tasks (if required). • Free migration RedBook and developerWorks articles on migration • No Charge Migration Assessment Workshop for qualified customers Now easier then ever before to migrate your applications to WebSphere Application Server (1) Liberty Profile or (2) WAS v7, v8, v8.5, v8.5.5 WebSphere Migration Toolkit (Eclipse and RAD plugins) WAS 5.1 – 8.x WebLogic Oracle OC4J (OAS) Tomcat IBM migration tools and offerings: http://whywebsphere.com/?s=migration (a) Java, JSP source and DDs (b) Server configuration objects JBoss new

  110. 110. 110 Oracle software licensing does not permit soft partitioning Logical/soft partition with WAS ND on 2 cores Logical/soft partition without WAS on 6 cores WebSphere AS ND is licensed for 2 cores License & support cost for 5 years= $53,928 WebLogic Server Enterprise is licensed for 8 cores. License & support cost for 5 years = $210,000 VMware image with WebLogic Server Enterprise on 2 cores VMware images without WebLogic on 6 cores (one still must pay for these) You pay Oracle for all CPUs on a server vs. CPUs that are assigned to the logical VM. Oracle does not allow the use of soft partitioning as a means to determine or limit the number of software licenses required for any given server. Read detailed analysis here: http://bit.ly/1JZFy8V Example: Based on publicly available information as of 7/10/2015 comparing Oracle WebLogic Server Enterprise Edition to IBM WebSphere Application Server Network Deployment. Both include maintenance and support for 5 years. IBM: 70 Processor Value Units per core, Oracle: 0.5 processor multiplier, both are on an x86 server, 2 sockets, quad core each.
