Technical Deep Dive into IBM WebSphere Liberty Dr Alex Mulholland WAS Liberty Architect

Please Note Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will experience will vary depending upon many factors, including considerations such as the amount of multiprogramming in the user’s job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

•  WAS leads on per Processor

performance as well beating WL 12.1.3 on the latest Intel Haswell EP processors as per results published on SPEC

IBM is World Leader in Enterprise Performance

Both published Feb 2015

… but you asked us for something more…..

•  Lightweight •  Composable •  Simple •  Flexible •  Dynamic •  Open & Extensible •  Cloud-ready

…. but as production-ready as the original….. …. with even higher management scale!

Simple to configure

24

•  ONE required configuration file •  ${wlp.install.dir}/usr/servers/server_name/server.xml •  User configuration for kernel and features

•  Optional files in same server directory •  server.env –  read by server script –  useful to override locations

•  eg. JAVA_HOME, WLP_USER_DIR, and WLP_OUTPUT_DIR •  jvm.options –  provided to JVM at startup –  JVM settings, system properties

•  bootstrap.properties –  to initialize core runtime (before XML config is read) –  predefined properties –  any custom property, variable for XML config etc

Simple to configure

25

•  All features have useful built-in defaults for their XML config

View the defaults easily in the WDT config editor

•  Some default config instances are also provided

<distributedMap id="defaultCache” jndiName="services/cache/distributedmap” memorySizeInEntries=”5000" cacheProviderName="default"/>

Attribute values for default instances can be overridden in server.xml

Simple to configure

26

•  server create command generates simple working server.xml

!  Runs servlets and JSPs

!  Default endpoint shown to make port overrides easy

Simple to share config files

27

${wlp.install.dir}/usr/servers/server_name/server.xml

<server description="new server"> <featureManager> <feature>jsp-2.2</feature> </featureManager> <include location="${shared.config.dir}\common-config.xml" /> </server>

•  Include files from local filesystem or network

derbypath=/usr/derby

bootstrap.properties file

<variable name=”derbypath" value=”/usr/derby" />

server.xml or included xml file

export derbypath=/usr/derby

environment variable

<fileset id="DerbyFileset" dir="${derbypath}" includes="derby-10.10.1.1.jar" />

•  Use variables to maximise sharing

${wlp.install.dir}/usr/servers/shared/config/common-config.xml

Simple to update •  Architectural Goal: Zero migration for unchanged apps

Bring your config

Choice: Features limit runtime behavior change Existing features remain unchanged eg. servlet-3.0 New feature versions contain updates, eg. servlet-3.1 No custom properties for behavior switching

Point to your existing JRE Within supported software levels. Java 6 will not last forever New Java EE features may require higher versions of Java

8.5.5.2

8.next

Your configuration, applications,

resources WLP_USER_DIR

java -jar wlp-developers-runtime-8.5.5.2.jar

java -jar wlp-developers-runtime-8.next.jar

Spec updates often force behavior changes

invalid configuration

Existing features run on updated kernel •  support existing applications with no change in

behavior New features are available for new and changed applications These features are singletons and cannot be configured into the same server instance

31

Java EE 6 & 7 toleration

servlet-3.1

websocket-1.0 (servlet-3.1)

A full feature stack is always supported

jsp-2.2 jsf-2.0 websocket-1.0 etc… servlet-3.0

Some EE7 features will prereq others, affecting the allowed configurations

servlet-3.1

jsf-2.0 jsp-2.3 el-3.0

Not all combinations are possible, per spec requirements and practicality

servlet-3.0

jsf-2.0 jsp-2.3 el-3.0

8.5.5.5 runtime

Flexible Java support •  Bring your own Java…6, 7 or 8

32

Develop and test apps on your macbook

Flexible deployment: server package •  Package runtime, config and app in an archive

33

myapp.war server.xml runtime

minify option packages only the runtime features used by the server

server package myServer –include=minify

•  ftp to hosts, unzip and run

Resulting installs fully supported with fix packs and iFixes
