Websphere Application Server
Websphere Application Server (WAS) Community Edition is an open source application
server software based on Apache Geronimo. It is the main competitor to Jboss.
Community Edition integrates Apache Tomcat with several of the most commonly
used open source components. IBM began to offer customers solutions based on Apache
Geronimo in May of 2005 when it acquired Gluecode Software.
It launched WAS Community Edition in November of 2005. Key features of Community
Edition include:
- J2EE 1.4 certification with support for both IBM Java Virtual Machine (JVM)
and Sun® JVM. IBM JVM is an industrial-strength performance leader and also
the same JVM shipped with other WebSphere Application Server products.
- Apache Tomcat as the default Web container.
- Easy-to-use, fully supported administrative console.
- Supports Web tier clustering and load balancing.
- Supports hot deployment and remote deployment via both console and the Eclipse
Integrated Development Environment.
- IBM Cloudscape V10.1 database is embedded in Community Edition and supported
for use in development and production.
- Supports DB2®, Oracle® databases, Microsoft® SQL Server, and MySQL database
server. IBM DB2 JDBC driver is included in Community Edition.
- InstallShield installation with small footprint download packages. Community
Edition can typically be installed in less than five minutes; ISV vendors can
easily embed Community Edition.
- IBM WebSphere product look and feel.
- Migration aids from Gluecode Standard Edition, Apache Geronimo, and Apache
Tomcat to Community Edition, and from Community Edition to other WebSphere Application
Server products.
- IBM LDAP integration.
- Eclipse plug-in J2EE profiling feature that alerts you when you are using
non-J2EE APIs in your application.
- Documentation.
- Liberal product license; users can freely use Community Edition in
development, testing, and deployment.
- IBM world-class product support available for a version for 1.5 years. (IBM
Apache Geronimo support requires more frequent updates since it is tied closer
to the Apache Geronimo community.)
When you download WebSphere Application Server Community Edition, you are automatically
entitled to
limited online support during a 30-day trial period, at no charge.
Community Edition system prerequisites:
- Windows® platforms on Intel® Architecture - 32 bit (IA-32) processors
- Microsoft Windows Server 2003 with Service Pack 1 (SP1)
- Microsoft Windows XP Professional Edition with Service Pack 2 (SP2)
when restricted to a development environment
- Linux® platforms on Intel Architecture - 32 bit (IA-32) processors
- Red Hat Enterprise Linux Version 4 Update 1 through Update 3 (4u1-4u3)
WS, ES, AS
- Novell® SuSE Linux Enterprise Server 9 Service Pack 2 through Service
Pack 3 (SP2-SP3)
Community Edition can run on other platforms, but one of these environments must
be used to obtain support, if desired:
- A supported Java environment:
- IBM Java 2 Standard Edition (J2SE) Software Development Kit (SDK) Version
1.4.2 SR4-1
- IBM Java 2 Standard Edition (J2SE) Java Runtime Environment (JRE) Version
1.4.2 SR4-1
- Sun® Microsystems Java 2 Standard Edition (J2SE) Software Development
Kit (SDK) Version 1.4.2 build 1.4.2_10
- Sun Microsystems Java 2 Standard Edition (J2SE) Java Runtime Environment
(JRE) Version 1.4.2 build 1.4.2_10
If you do not already have a supported Java environment, you can download an
installation bundle that includes the recommended IBM J2SE SDK
WebSphere Application Server is Java 2 Enterprise Edition (J2EE) application
server and development environment. Among stated by IBM the benefits of J2EE are
the following:
A simplified architecture based on standard components, services and clients,
that takes advantage of the write-once, run-anywhere Java technology.
- Services providing integration with existing systems, including Java DataBase
Connectivity (JDBC); Java Message Service (JMS); Java Connector Architecture
(JCA); Java Interface Definition Language (Java IDL); the JavaMail API; and
Java Transaction API (JTA and JTS) for reliable business transactions.
- Application development is focused on unique business requirements and rules,
rather than common application aspects, such as security and transaction support.
This improves productivity and shortens development cycles.
- Scalability to meet demand, by distributing containers across multiple systems
and using database connection pooling, for example.
- A better choice of application development tools and components from vendors
providing standard solutions.
- A flexible security model that provides single sign-on support, integration
with existing security schemes, and a unified approach to securing application
components.
As typical for IBM WebSphere Application Server is available in
multiple packaging options. Each package is designed to provide a tailored environment
for a specific set of clients.

This IBM Redbook provides detailed information about
problem determination for various WebSphere products
in a real-life scenario. It is a valuable resource
of information for IT administrators, IT specialists
and application developers.
Part 1, “Introduction”
offers an explanation of how the book is organized
and how it should be used for problem determination.
It also provides details about the solution chosen
for the book to better understand the environment
and to provide a real-life scenario.
Part 2, “Problem Determination details” is the
core of the whole book. This part starts with two
chapters discussing problem determination tools,
one chapter for the runtime environment (AIX) and
one for the development environment (mainly WebSphere
Studio Application Developer V5). The following
chapters go into details about problems (symptoms)
with each product: WebSphere Application Server
Enterprise V5, WebSphere MQ V5.3 and WebSphere Business
Integration Message Broker V5.
The “Appendixes” extend the book with problem
determination tools on other platforms, mainly z/OS.
It also provides insight into the methodology used
for this book to document problems, tools and problem
determination techniques.
IBM Software on UltraSPARC T1 License Policy
IBM announced their
new Software license policy for UltraSPARC T1 chip based Sun Servers. A 4 core
or 6 core T1 chip requires 2 software license entitlements and a full 8-core T1
chip requires 3 software license entitlements. (Its a win-win considering before
this announcement it was 8 software license entitlements for a 8-core T1 chip.
One thing to also note that a Sun Fire X4200 /X4100 with dual core Opterons require
1 license entitlement for every dual core chip. (Read the foot note for descriptions
of "Multiple server families" which includes SunFire x64 servers.
The best way to distribute the news is to point people to the
PDF Copy of the IBM Software License Policy

10.7. Monitoring
WebSphere Application Server.
What should you configure in osagent.conf.xml
to monitor your WebSphere application server / J2EE application ?
10.7.1. Checks for monitoring
WebSphere application server
- Checking running java jvm processes with
PROC
- Checking open sockets on port ( web-container(s), admin-console,
servlet container ) with
SOCKETS
- check, if your web-container returns a defined result
WEBAPP
- Checking the SystemOut.log / SystemErr.log with
LOGS
- Checking your WebSphere MQ (aka MQSeries) with
Section 9.21, “Configuration for the
mqs check”
10.7.2. Example
configuration for monitoring WebSphere

A new research report found that WebSphere Application Server (WAS) Community
Edition -- IBM's (NYSE:IBM -
News) open source application
server software based on Apache Geronimo -- is gaining share nearly three times
as fast as rival JBoss.
According to Evans Data Corporation, in a single year WebSphere Application
Server Community Edition gained 16 points of market share with Eclipse developers,
versus only a 6.6 share gain for JBoss.
The second Annual Eclipse Global Enterprise Report from Evans Data Corporation
surveyed software developers on their attitudes, awareness, perceptions and
concerns of developers regarding Eclipse and Eclipse-related products. Eclipse
is an open source, platform independent framework for developing software applications.
... ... ...
WAS Community Edition, which is free to download and use, pre-integrates
Apache Tomcat with several of the most commonly used open source components,
such as web services, security, authentication, messaging and web tier clustering.
IBM began to offer customers solutions based on Apache Geronimo in May of 2005
when it acquired Gluecode Software. It launched WAS Community Edition in November
of 2005.
... Additionally, Novell's Integrated Stack for SuSE Linux (ISSLE) includes
WAS Community Edition and IBM DB2 Express-c.
