What is WebSphere Application Server Liberty Profile?

 A new flexible dynamic profile of WAS which is focused FIRST on the development experience.

– Fast

– Lightweight

– Simplified Configuration

 Fidelity with full-profile WAS

– But radically refactored to focus on the development experience

What is WebSphere Application Server Liberty Profile?

 Support for Liberty Profile in Rational Application Developer

– Enterprise development - advanced programming, cloud, collaboration, and quality tools – Available stand-alone or bundled in WAS - Tools Edition

and WAS Network Deployment - Tools Edition

 Support for Liberty Profile in WebSphere Application Server Development Tools for Eclipse – Subset of RAD focused on core programming models

– Simple Eclipse feature update for Eclipse 3.6 (Helios) or 3.7 (Indigo) – Available on Eclipse Marketplace for Eclipse Juno, Kepler

– Available unsupported at no charge, or supported for a fee – WAS for Developers – Tools Edition for Eclipse

 Development tools can install the runtime.

 Additional platform support for z/OS - runtime only, i5/OS

and Mac OS runtime & tools (development only not supported for production)

Simplified server configuration

Simplest case: one XML file

for all server configuration

Editable within the

workspace

Exportable, shareable,

versionable

ws-security.xml server.xml etc. resources.xml

X

No need for Admin Console, wsadmin,

or enhanced EARs

Simplified server configuration

<server>

<featureManager>

<feature>jsp-2.2</feature>

<feature>jdbc-4.0</feature>

</featureManager>

<logging trace.specification="webcontainer=all=enabled:*=info=enabled" />

<application type="war" id="tradelite" name="tradelite" location="tradelite.war" />

<jdbcDriver id="DerbyEmbedded" libraryRef="DerbyLib"/> <library filesetRef="DerbyFileset" id="DerbyLib"/>

<fileset dir="${shared.resource.dir}/derby" id="DerbyFileset" includes="derby.jar"/>

<dataSource id="DefaultDatasource" jdbcDriverRef="DerbyEmbedded" jndiName="DefaultDatasource">

<properties createDatabase="create" databaseName="${shared.resource.dir}/data/product"/> </dataSource>

</server>

features control which capabilities (bundles) are installed in the server

'singleton' configurations specify properties for a runtime service like logging

'instance' configurations specify multiple resources like applications and datasource definitions

Any of this configuration could be put into a separate xml file and 'included' in this 'master' configuration file

(11)

Flexible configuration

 Shareable configuration snippets <server>

...

<include location="http://cfgserver/global.xml" />

<include location="${shared.config.dir}/global.xml" /> <server>

server.xml

 Configuration can be componentized at any level of granularity, from one file to many (update configuration for thousands of servers by one xml file change)(

 Can use WDT to associate configuration snippets with a server configuration.

 Visualization through WDT tools as a single logical view.

Flexible Configuration

 Configuration defaults are specified by contributing features

 Configuration by exception – any property can be overridden in user-specified server config

 Config can be changed dynamically, changes are “observed” and are injected back into the

Liberty profile for i

 iAdmin command

– supports operating a Liberty profile server on the IBM® i platform – wlp/lib/native/os400/bin

 iAdmin task [options] – task could be:

• POSTINSTALL – configures server to run in QWAS85 subsystem • PREUNINSTALL – removes objects created by POSTINSTALL • GRANTAUTH – grants QEJBSVR user necessary permissions – options

• Required only for GRANTAUTH task • --userprofilename QEJBSVR

• Optional for GRANTAUTH (ignored by other tasks)

• --outputdir wlp_user_dir – directory for server generated files • --rolename role_name – the only supported role is server • --userdir wlp_user_dir – shared resources directory

(16)

Deployment options

 An “Embedded Server” profile is a production instance of the configured Liberty server type. – Package the application, configuration and server you just tested into an archive file.

• server package server_name --archive=package_file_name.zip --include=all – Application centric – server pre-configured for a specific application.

(17)

Deployment of applications

 Drag & drop

– dropins directory

• ${server.config.dir}/dropins

– Place the archive file with its identifying suffix (ear, war, wab, and so on) directly into the /dropin

 Add to server configuration file

<application context-root="helloworld" type="war" id="helloworld" location="helloworld.war" name="helloworld"/>

 Context root is determined in the following precedence: – context-root in the server.xml file

– application.xml, if an EAR application – ibm-web-ext.xml, if a web application

– name of the application in the server.xml file, if a web application – Manifest.MF, if a WAB application

JVM properties

 File jvm.options

– jvm-specific start options • for example -X arguments – One option per line

 ${wlp.install.dir}/etc/jvm.options – Settings apply for all servers

 ${server.config.dir}/jvm.options

(19)

Starting and stopping server from command line

server command in ${wlp.install.dir}/bin directory

 server start <servername> – Start server in background

 server run <servername> – Start server in foreground

– Write console output to the window – Ctrl+c or kill to stop the server

 server debug <servername> – Start server in debug mode

 server stop <servername> – Stops the server

 server status <servername>
