The document discusses how the WebSphere Application Server - Configure plug-in for IBM UrbanCode Deploy can be used to automate configuration management for WebSphere Application Server. It describes how the plug-in discovers WebSphere configuration, templates it, and applies configuration across environments. The plug-in supports simplifying configuration data, using tokens and snippets, live configuration comparison, and WebSphere migration. A demo is shown promoting dynamic cluster configuration from a development to quality assurance environment. Resources and prerequisites for using the plug-in are also provided.

- 6. WebSphere Configure Plugin – Discover Steps are provided to pull configuration data from WAS, parse it to cell, node, server, and cluster components, and templatize the configuration data so it may be applied to multiple environments 5 Deployment Manager Node Node Node Node Node Node Node Node Node Cell Cell Server Server Server Server Server Server Artifact Library
- 7. WebSphere Configure Plugin – Apply Applying the configuration uses the data from the UCD repository to update the configuration data on the target middleware environment 6 Deployment Manager Node Node Node Node Node Node Node Node Node Cell Cell Server Server Server Server Server Server Artifact Library
- 8. WebSphere Configuration Plugin – Compare • Compare will compare the data from the UCD repository with the live middleware environment 7 Deployment Manager Node Node Node Node Node Node Node Node Node Cell Cell Server Server Server Server Server Server ? = Artifact Library
- 9. Sample Application/Processes Getting started with configuration data
- 10. Examples are Provided • Example Application – Included with the plug-in – Applies changes and manages live compare • Example Generic Processes – Several example generic processes are included with the plug-in – Additional example generic processes are available on the plug-in site – Example processes walk through discovery/extract/templatize/component creation 9
- 11. Simplifying Configuration Data Getting what you want without the extras
- 12. Simplifying Discovered Configuration Data • The example processes assume Discovery is run at the Cell level – This discovers everything, resulting in large amounts of config data – In large environments, it may take hours to run • It is possible to run Discovery at a Node, Server, or Cluster scope – Results in less configuration data – Executes much more quickly 11
- 13. Simplifying Discovered Configuration Data • Users may also specify which config objects they wish to discover • Returns the specified objects and their children • May specify multiple config objects • Example: – Specify JDBCProvider as the config type to discover – Run Discovery at the Server scope – Result: Only the config data for that server’s JDBC Providers is returned 12
- 14. Simplifying Discovered Configuration Data • A configuration file may be split into multiple files • Configuration files are merged before Apply is executed 13
- 15. Tokens & Snippets Giving you flexibility in managing configuration data
- 16. Adding Tokens to Configuration Data • Properties in your configuration data may be replaced by tokens • Tokens are then replaced with the corresponding UCD property values as a process is executed 15
- 17. Snippets • Configuration data may be broken down into smaller pieces called snippets • May represent a configuration object that may be applied independently (example: a JDBC Provider to be added to a node) • May be a piece of configuration data extracted for easier management (JVM settings extracted to their own file but applied as part of a server’s overall configuration) 16
- 18. Applying Snippets/Tokenized Values • Processes may be created to replace tokenized values on the fly – “Modify JVM heapsize values on an application server” – Value(s) are not saved in config data but is applied to new server WebSphere 17
- 19. Live Compare Config Drift Detection
- 20. Live Compare • In IBM’s ideal world, WAS configuration changes would only be made through IBM UrbanCode Deploy • In the real world, users may make WAS configuration changes without going through UrbanCode Deploy • Steps are provided to detect changes between your configuration data and what is live in WAS • Processes may be built to perform certain actions if changes are detected (email someone, re-apply configuration changes, etc.) 19
- 21. WebSphere Migration Support Are you moving your configuration data from WebSphere 7 to WebSphere 8.5.x?
- 22. WebSphere Migration • Capture configuration data from your WebSphere 7 instance • Deploy configuration data to WebSphere 8.5.x instance • Recent customer engagement promoted configuration for a single cell instance that contained 7 nodes, 87 dynamic clusters and 91applications – Moved from WebSphere 7.0.0.39 to WebSphere 8.5.5.9 – Applications redeployed using the WebSphere Application Server – Deploy plugin – Can use their captured configuration data as the basis for managing their WebSphere configuration devops needs going forward 21
- 23. Demo Promoting Dynamic Cluster Configuration from DEV to QA
- 24. Demo • Topology discovery • Example process for WAS ND with dynamic cluster • Show how configuration data is stored in UCD (could also use alternative source controls like Git, Rational Team Concert, etc) • Add components to resource tree • Show example application and its processes • Compare configuration data versions • Promote across environments featuring Dynamic Clusters • Rollback 23
- 25. Resources
- 26. Prerequisites • Urban Code Deploy 6.2 or later (6.2.0.2 or later strongly encouraged) • WebSphere Application Server – Configure plug-in (Recommend the latest version) • WebSphere Application Server – Deployment version 92 or later • If using Dynamic Clusters, WebSphere 8.5.5.7 or later 25
