Java changes – Java SE 8 & decoupled JVMs

• WAS V9 traditional requires 64-bit Java SE 8 (5761-JV1/5770-JV1 option 17)

• 32-bit JVM is not supported for WAS traditional runtime

• 32-bit JVM is supported for Liberty

• Distributed version of WAS V9 now supports a decoupled JVM like IBM i

• Meaning the JVM life-cycle is now independent from WAS and can be updated independent from WAS fixpack level. Used to be shipped with WAS image

• The default JAVA Max heap (-Xmx) is calculated as following if it is not defined by the user:

• 25% of available memory up to a MAX of 4 Gbytes.

• If available memory cannot be calculated then it is set to the JVM default which is 2 Gbytes for JDK 1.8

• The managesdk command: The SDK names are changed from

1.<SDK version>_<bitness> to <SDK version>.0_<bitness>. Example:

1.8_64 becomes 8.0_64

7


wsadmin Scripting Change

• Updated wsadmin jython scripting language version to jython 2.7

• jython 2.1 and JACL still functional and supported, but deprecated

• wsadmin will detect the language used and switch to JACL if the first line entered is in JACL

• By default, wsadmin will assume a jython 2.7 script

Note: most old jython scripts will work with jython 2.7

• jython 2.1 can be selected with command-line option

-usejython21 true

• List of deprecated commands and features

Service stream model changes

16


Service stream Model Changes

▪ WAS v7/v8/v855 service model remains unchanged, IBM will continue to supply group PTFs for WAS fix packs until EOS of the product(s)

▪ WAS v9 is serviced using either:

▪ GUI

▪ IBM i Web Admin GUI provides an easy to use interface for installing fix packs for WAS v8, v855 and v9

▪ Command line

▪ Using IBM Installation Manager (IM), administrators may install fix packs using either the IBM live repository or create their own local repositories

▪ Details on both options are at this IBM POWER Systems webpage (http://www-03.ibm.com/systems/power/software/i/websphere/v90/index.html) under the “Fix packs” tab

▪ The following slides have screen shots and commands used to install

http://www.redbooks.ibm.com/redpieces/abstracts/sg248048.html



• The extended support dates (EOES) for WAS 7.0 and 8.0 will only cover WAS

updates and not JDK 1.6. Users of WAS 7.0 and 8.0 will acknowledge that

IBM will not offer support for new JDK 1.6 problems discovered after Dec 31st 2017

WAS 8.5.5: JDK 1.6 meta data will be removed after April 30th 2018

The above will affect users on IBM i V7R1 and V7R2

• The JDK 1.6 meta data will be removed in a future fix pack after April 30th 2018

• The removal of the metadata may prevent an application server or a WAS

command from running if either the default WAS profile or the command default

JDK is set to use JDK 1.6

• Users are advised to update all their WAS profiles, command default and

new profile default to use JDK 1.8 and start testing their WAS environment

• Users can upgrade to JDK 1.7 but are advised to update to JDK 1.8

Should be done before April

30th 2018

40



• Before you upgrade a profile to use JDK 1.8 or 1.7, make sure you have the 1.8 or

1.7 IBM JDKs installed on you IBM i V7R1 or V7R2 system

IBM i V7R1 IBM i V7R2

JDK 1.8: 5761JV1 options 16 and 17




• Use the WAS_HOME/bin/managesdk command to update the WAS profiles,

command default and new profile default JDK

Example:

STRQSH

cd /QIBM/ProdData/WebSphere/AppServer/V85/ND/bin

./managesdk -setNewProfileDefault -sdkname 1.8_64

./managesdk -setCommandDefault -sdkname 1.8_64

./managesdk -enableProfileAll -sdkname 1.8_64 -enableServers

IBM i V7R1 memo to users and IBM i V7R2 memo to users have more

information. Please search for managesdk in the documents.

Sets new profile JDK

Sets command default JDK

Updates all profiles’ JDK

https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_72/rzaq9/rzaq9.pdf



• IBM will make every effort to make the removal of JDK 1.6 metadata

in a future fix pack after April 30th 2018 as painless as possible but user

intervention may still be required

• Fix pack exit code will be added to update the JDK(s) of the default profile,

command default and new profile default to 1.8 or 1.7 depending on the

availability of the JDK on the machine

• IM requires JDK 1.7 to be installed, so at a minimum, the exit program will

update the JDK to 1.7

42


Liberty Product Overview

43


Lightweight composable runtime

44


• Liberty is a lightweight Application Server for hosting Java EE and other

applications during development, test and production.

• Supports Java EE 6 and 7

• Has a small footprint compared to the traditional WebSphere Application

server, 250 Mbytes versus > 1 Gbytes

• Fast startup time. Few seconds (5.5 seconds on IBM i depending on the

system’s model and Liberty features used versus > 30 for traditional

WebSphere)

• Can be installed using IM (IBM Installation Manger), or

• Can be installed by extracting the wlp<version>.zip file Into a folder in

the file system.

45


Configuration, start/stop, logging, install and

administration

46


Liberty directory locations and properties

• ${wlp.install.dir}

Root of the Liberty installation, eg:

/QIBM/ProdData/WebSphere/Liberty/BASE

• ${server.config.dir}

Server configuration directory, eg:

/QIBM/UserData/WebSphere/Liberty/BASE/wlp/usr/servers/<server_name>

• ${server.output.dir}

Server output directory, eg:

/QIBM/UserData/WebSphere/Liberty/BASE/wlp/output/servers/<server_name>

47


Configuration

• A Liberty Server is created by a simple command:

${wlp.install.dir}/bin/server create myServer

Under ${server.config.dir}, you will see:

• The folder structure is very simple and there is one main configuration file

server.xml. You seldom have to edit any other file than server.xml

• In contrast to traditional WebSphere, Liberty has fewer configuration files

• In addition to the above files you can add a jvm.options file to define JVM

options for Liberty server to use

bootstrap.properties defines

properties used in server.xml

server.xml is the

main configuration

file

server.env is used to define env

variables, eg JAVA_HOME

apps and dropins is

where the apps are

dropped and

expanded

48


Configurationserver.xml:

<server description="new server">

<featureManager>

<feature>jsp-2.2</feature>

<feature>ssl-1.0</feature>

</featureManager>

<httpEndpoint httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint" host="ut30p24" />

<keyStore id="defaultKeyStore" password=“{xor}JjAqLQ8+LCwoMC07" />

<applicationManager autoExpand="true"/>

<application context-root="hello" type="war" location="Sample.war"/>

</server>

• <featureManager> element specifies features enabled by the current Liberty server and

usually indicates the features needed to run the current Application(s). The fewer the

faster!

• Execute “${wlp.install,dir}/bin/featureManager featureList /tmp/list.xml”

to list all supported features and their dependencies. Some features bring in other

dependent features. Eg, jsp-2.2 depends on servlet-3.0

49




<featureManager>



</featureManager>





</server>

• <httpEndpoint> element specifies the HTTP and HTTPS ports of the server. Liberty

defaults are 9080 and 9443 respectively.

50




<featureManager>



</featureManager>





</server>

• <keystore> element specifies password for the server’s SSL keystore

• Use ${wlp.install.dir}/bin/securityUtility to encode the password

${wlp.install.dir}/bin/securityUtility encode password

51




<featureManager>



</featureManager>





</server>

• <applicationManager> element can be used to expand the WAR or EAR files into the

${server.config.dir}/apps/expanded folder.

52




<featureManager>



</featureManager>





</server>

• <application> element can be used to set various attributes of a deployed application from

context root to security roles.

53


Configuration

• Please see Configuration elements in the server.xml file for a list of

all configuration elements used in Liberty’s server.xml configuration

file: https://www.ibm.com/support/knowledgecenter/en/SSD28V_8.5.5/com.ibm.webspher

e.wlp.core.doc/autodita/rwlp_metatype_core.html

https://www.ibm.com/support/knowledgecenter/en/SSD28V_8.5.5/com.ibm.websphere.wlp.core.doc/autodita/rwlp_metatype_core.html


Starting and stopping a serverLiberty server can be started in foreground and background mode:

Foreground mode:

- From Qshell:

${wlp.install.root}/bin/server run <server_name>

The above will run the server in the foreground so you can see the

console.log output on your screen; useful for development phase:

55

Application available message

Features installed. Not everything is

loaded like in traditional WAS


Starting and stopping a serverBackground or batch mode:

- From Qshell:

${wlp.install.root}/bin/server start <server_name>

The above will run the server in the background in the QWAS9 subsystem

or as a JVM job depending on how Liberty was installed.

Stopping a Liberty server:

${wlp.install.root}/bin/server stop <server_name>

56


Logging and tracing

• All logs are kept in ${server.output.dir}/logs folder:

• console.log has all standard out and error output from the

server. File is truncated on a new start

• messages.log same as above with more messages

• trace.log does not exist by default, contains all enabled tracing

Tracing:

Tracing can be enabled by adding a logging element to server.xml:

Example:

<logging traceSpecification="*=info:app.manager*=all" traceFormat="ENHANCED"

consoleLogLevel="INFO"></logging>

The above will create a trace.log in the logs folder specified above.

All config changes in Liberty are dynamic. You can update the trace

specification string without having to restart the server.

57


Installation

1- Preloaded:

Liberty can be configured to be preloaded on new IBM i systems and is part of the ESS

(Entitled Systems Support) catalogue and can be ordered at any time by IBM i systems

owners.

- PID 5733-WE3 contains WebSphere Application Server Base edition 9.0

and Liberty BASE 9.0, eGA 6/2016

- Users who have Liberty 8.5.5 can apply Liberty 9.0 fix packs on top of their current

installations as part of the continuous delivery model

58

http://www-304.ibm.com/servers/eserver/ess/index.wss


Installation

2- Installed using IBM Installation Manager (IM):

Liberty can be installed using IM. Please see Using the IBM Web Administration for i

Console for a tech note on how to install Liberty and other WAS products using IM.

Please note that if Liberty is installed using IM, then the server jobs will

user profile similar to traditional WAS.

===> wrkactjob SBS(QWAS9)

59



Installation

3- Install using the unzip archive method

Users can download the latest Liberty Image from wasdev:

https://developer.ibm.com/wasdev/

• Select Download Latest Stable Release, accept the license terms

• Save the .zip file to an ifs folder on IBM I and unzip it

• cd to the wlp/bin folder and create/start a server

The Liberty server will run under the user profile which started the server and not QEJBSVR

Using the iAdmin command:

• Please see the iAdmin command for information on how to set up Liberty to run in the

WAS9 subsystem and under QEJBSVR user profile.

• Note: The iAdmin command will not add Liberty install to the

IBM Installation Manager’s list of installed products.

60

https://developer.ibm.com/wasdev/

https://www.ibm.com/support/knowledgecenter/SSEQTP_liberty/com.ibm.websphere.wlp.core.doc/ae/rwlp_command_iadmin.html


Administration

• Liberty does not have the extensive built in admin capability that traditional WebSphere

has such as wsadmin or ws_ant

• Liberty provides additional tools and methods for administrators such as JMX. Please

see Administering Liberty for more details

• The WebSphere® Application Server Developer Tools for eclipse can be used to update

Liberty configuration and test the apps on a development work station (windows™,

linux or macOS™)

• After the user is satisfied with the WDT results, the server.xml and the app can be then

copied to the IBM i and tested

• A Liberty “admin center” GUI is provided which can be used to start/stop apps, view

server.xml configuration elements and update them and monitor the JVM such as

heap usage, active threads, etc

61

https://www.ibm.com/support/knowledgecenter/SS7K4U_liberty/com.ibm.websphere.wlp.zseries.doc/ae/twlp_admin.html

https://developer.ibm.com/wasdev/getstarted/


Administration

• The Liberty Admin Center is a feature that has to be installed and configured

• Users do not have to have admin center installed in production for efficiency purposes

To enable Liberty Admin Center:

• Install the feature

${wlp.install.root}/bin/installUtility install adminCenter-1.0

• Add the following feature to server.xml under <featureManager>:

<feature>adminCenter-1.0</feature>

• Add the following elements:

<quickStartSecurity userName="admin" userPassword="password" />

<keyStore id="defaultKeyStore" password="{xor}Lz4sLCgwLTs=" />

• The above will enable a Liberty Admin Center accessible via:

http://<server_name>:<http_port>/adminCenter

User id: admin, password: password

The connection will use https62

Dynamic Configuration, no restart for most updates

and Plugin-cfg.xml generation

64


Dynamic configuration

• Updates to the server.xml configuration file do not require a server restart

• All configuration updates to server.xml are rendered available by Liberty, examples:

• Dropping new apps into the dropins folder

• Adding or updating a data source

• Enabling or disabling security

• Adding or removing a trace specification.

• Adding or removing a feature

• Automatic updates can be turned off by adding the following element to server.xml:

<config updateTrigger="disabled"/>

In this case, The Liberty server will need to be restarted for config changes to take

effect.

65


plugin-cfg.xml

• plugin-cfg.xml is used by the WebSphere plugin to configure routing of http/https

requests to apps from IHS (IBM HTTP Server)

• The Liberty server generates this file for its configuration when it is started, or if

server.xml config is updated, or an app is deployed or undeployed

• This file is for a single app server configuration only

• The plugin-cfg.xml is generated in ${server.output.dir}/logs/state folder

• If you need to generate a plugin-cfg.xml file for a Liberty collective, use the Liberty

tool, found at ${wlp.install.dir}/bin/pluginUtility

• The Liberty generation of this file is different from traditional WAS and may require

some editing and manual setup steps as described in this tech note

66



Continuous delivery model

67


Liberty releases and fix packs

• Liberty v8.5.5.0 was first released on 6/2013 as a stand alone install instead of a feature of

traditional WebSphere Application Server v8.5.0

• Liberty v9.0 was first released on 6/2016 and the versioning of the product was changed from

the usual 9.0.0.x to Y.R.M.F: year.release.modification.fixpack format. Fix packs are now

released quarterly

• Based on the above, the version of the first Liberty 9.0 release is 16.0.0.2. The latest fix pack

is 17.0.0.1 which is Year 17 and 1st Quarter.

• Execute the following to obtain the fix pack level of a Liberty install:${wlp.install.dir}/bin/productInfo version

• Liberty follows the continuous delivery model which means there are no hard

migrations any more. Applying the fix pack will get you all the new function.

For example, the websockets-1.0 feature was added in Liberty v8.5.5.5.

Users do not have to upgrade to new releases to get new function! 68


Liberty fix packs can be applied to 8.5.5 and 9.0Liberty Continuous Delivery

69

WAS V9 introduces a new 9.0.0.0 service stream for traditional WAS fixpacks.

WAS Liberty follows a continuous delivery model with a single service stream .

Liberty fixpack numbering is set to:

Y.R.M.F: year.release.modlevel.fixpack

eg 16.0.0.4 would be the fourth fix pack in 2016

The next fixpack after 8.5.5.9 is the second fixpack of 2016 and is numbered 16.0.0.2.

It is just a number - there is no migration required at all to the first V9 release of Liberty: 16.0.0.2.

Migration to Liberty

71



• IBM provides tools to migrate traditional WebSphere apps and configuration to

Liberty. The tools support migration from JBoss™ and WebLogic™ as well

• The migration from traditional WebSphere to Liberty is done on an application basis

• The tools require you to specify your source WebSphere version, JDK level and in

some cases the JEE target level of certain technologies

Three Tools are provided:

1- A command line Migration Toolkit for Application Binaries which is used to scan

the Application and create various reports about the Application:

- Application evaluation report. J2EE technologies the Application uses

- Application Inventory Report (WARs , EARs, Servlets, JSP’s etc)

- Liberty feature list report (features used by the Application)

- Detailed migration analysis report which details potential problems
