IBM Installation Manager History and Overview

! IBM Installation Manager product was originally introduced to support the installation of IBMRational desktop products.

! Currently adopted by multiple products across IBM A single instance of IBM Installation Manager can manage the product lifecycle for any

IBM Installation Manager based product, from WebSphere, Rational, Lotus, or any otherbrand within IBM.

! Provide full product install lifecycle management

Install/Uninstall Update/Rollback (Fixpacks and iFixes) Modify (Add/Remove features)

! IBM Installation Manager supports Full Graphical User Interface (GUI)

Command Line (IMCL) mode and response file

! IBM Installation Manager can install the product directly from Product (DVD) media IBM Passport Advantage web site Customer internal enterprise intranet

IBM Installation Manager - Repository

! Contain one or multiple product offerings that have both meta-data and actual payload forthe offerings

! Meta-data describes such aspects of the offering as Name, version, supported platforms, etc Components of the offering (optional/required feature) Relationships between offerings and features of the offerings

! Repository normally contains full content required to install certain offering of variousplatforms, operating systems, etc.

! Different IBM Installation Managers on different machines can reference the samerepository.

! Repository topologies can be generalized in the following 3 categories Public repository (accessible to general public using URL)

Enterprise repository (located behind the firewall, accessed by multiple machines withinthe enterprise)

Local repository (used by single user, not shared with others)! Tools are provided to copy offerings from one repository to another.

IBM WebSphere Application Server Product Packages

! IBM WebSphere Application Server V8.0 has multiple product offering packages. e.g. ND, Base, Express, HTTP Server and etc

! These product packages are packaged in the product DVD media and also available in IBMPassport Advantage site.

! IBM Installation Manager V1.4.3 or later is required to install IBM WebSphere ApplicationServer V8.0.

Early Versions of Rational Application Developer Shipped with IM V1.4.2! Same product offering package can be used to install or any supported distributed

platforms.

Install WebSphere Application Server Silently

! IBM Installation Manager also provides command line interface.! The command line interface can be used for basic install/modify/update/uninstall operations.! IBM Installation Manager also have the capability to record an install response file.! The install operations can be rerun with the command line interface and the install response

file.

Migration impacts by overviewMigration impact is gated by two overarching factors

1. The versions involved in the customer Migration scenario Moving from V6.1 to V8.0 would be different than V5.1 to V8.0

2. The amount of change introduced in these and the inner versions Moving from V6.1 to V8.0 involves changes introduced by V7.0 and V8.0 Moving from V5.1 to V8.0 involves changes introduced by V6.0, V6.1, V7.0 and

V8.0

Choosing the

right

version! Question: Which WebSphere Application Server version should I migrate to? ! Answer, as always -

It depends

End of Service date for your current version

WebSphere Application Server V5.1 was September 2008 WebSphere Application Server V6.0.2 was September 2010 WebSphere Application Server V6.1 is September 2012 WebSphere Application Server V7.0 EOS has not been announced . Estimated

earliest EOS would be April 2014 (per IBM Software EOS policy). WebSphere Application Server V8.0 EOS has not been announced. Estimated

earliest EOS would be September 2016 (per IBM Software EOS policy). Characteristics of your targeted version

End of Service date for the version most likely an estimate Estimated time to next migration JEE/JDK levels relative to targeted version New WebSphere Application Server features that benefits your organization Version requirements of vendor or IBM products that you have or want Version your Enterprise has committed towards Fix Pack level

33/42



WebSphere Application Migration

! Java Runtime compatibility (JRE), component of Java Standard E JREs focus on binary compatibility which the previous release

compatibility certification suite New APIs and implementation changes may result in subtle differences

! Java EE (JEE) compatibility Newer JEE versions intend to support older JEE versions But in some cases breaking clarifications do exist JEE supports incremental upgrade

Modules within an application can be earlier versions ! In general WebSphere APIs very compatible

Many V4.x Applications interfaces unchanged (except for zOS)

Most V5.0/V5.1/V6.0/V6.1/V7.0 interfaces unchanged ! No guarantee applications will run unchanged

Changes maybe required for Java, J2EE or WebSphere APIs

34/42



Deprecation policy

! Deprecation policy in place for all WebSphere Application Server APIs

! API supported for 2 full releases from the point of deprecation or 3full years whichever is longer

! API may be removed at such point but not always! Deprecations and Removals are documented in InfoCenter! 5+3 support statement as of March 2007

Five for standard, three for extended support. Updated April 2008 to include selected products within the

Information Management, IBM Lotus, IBM Rational, IBM Tivoli andWebSphere

See references for link to specifics

V5.0.xV5.1.x

V6.0.x

New API introduced Deprecated but still supported Deprecated but still supported

JRE 6 differences Java EE specification changes or enforcements

Free download, use in Rational and Eclipse based scenarios

V7.0: Support for V5.1, V6.0 and V6.1

v8.0: Support for V5.1, V6.0, V6.1 and V7.0! Application Migration

No significant impacts in v8 No change in Java Runtime specification level

Java EE 6 upgrade but 84% of sub-specification levels unchanged

! IBM WebSphere Application Server Migration toolkit:http://www.ibm.com/developerworks/websphere/downloads/migtoolkit/

No more wading throughdocumentation and source

code or performing trial-and- error to determine what willbreak in your application!

35


36/42



Administration scripting choices! JACL or Jython?! JACL was the only choice initially! Jython is the preferred direction

More industry support Better performance Priority in future deliverables

! No need to convert JACL No longer deprecated!

It is now

Stabilized

meaning it will not be removed but it will nothave further investment

Conversion tool included since V6.1 and available in RAD viadownload

!

Suggest an evolution Create new scripts using Jython

37/42



Multiversion Tools and Techniques! Cross version plug-in support

Higher level Web Server plug-in can work to multiple

WebSphere versions

The URI for a machine must be unique in therouting rules for the plug-in

V7.0 supports V5.1, V6.0, V6.1 and V7.0

V8.0 supports V6.0, V6.1, V7.0 and V8.0! Coexistence

Different versions of WAS: same machine, same time

Requires port conflict resolution of concurrentlyrunning servers

All Servers, TCP ports, IP names, resources etc. are migrated

Applications are migrated by default but can be just built to be deployedlater if desired

An option for larger topologies! zOS migration is only within the same LPAR

Five Network Deployment strategies

1. Side by Side Create a new cell and populate with scripts or manually No runtime migration tools

2. In Place - Copy and replace the cell Recreates the exact V6.x/V7.0 configuration in V8.0 DMgr and nodes are migrated

3. In Place - Copy and replace the DMgr Recreates the exact V6.x/V7.0 configuration in V8.0 Add new V8.0 nodes and move incrementally

4. In Place - Copy and coexist Recreates the exact V6.x/V7.0 configuration in V8.0 Modify the ports in the new cell and coexist

5. Side by Side - Fine Grained

Create a new cell and incrementally copy existingconfiguration Uses an intermediate profile, runtime migration and
