Software as a service: Usage based metering and billing for multi-tenant Web service resources using IBM Tivoli Usage and Accounting Manager
This demo explores how a SaaS service provider can meter and bill usage of multi-tenant Web services and related resources like databases, portals and LDAP directory server, by users belonging to multiple tenants. A scenario is shown where IBM Tivoli Usage and Accounting Manager (ITUAM) and a Java Management eXtension (JMX) based usage logging component is used to meter the usage of Web services and its resources. IBM Tivoli Usage and Accounting Manager job files and report server is used to generate billing invoices, usage metrics, and graphs for tenants.

Utilizing IBM Directory Server proxy authorization (impersonation) within Web applications
Web applications providing gateway access to LDAP services, such as
an enterprise-wide phone and mail directory, are usually
designed to authenticate using an LDAP "superuser" account.
As a result, the user reads and updates the directory according
to the rights of that high-privileged account
instead of his/her own LDAP privileges.
IBM Tivoli Directory Server offers a powerful
feature, known as proxied authorization (RFC 4370),
which enables programmers to write applications
that authenticates themselves using a specific account but operates
on behalf of the real user, thus delegating all
privilege enforcements to the LDAP server.

Build a custom static parser plugin for LTA-JD
The huge amount of data to analyze after system failures poses the initial difficulty
in problem determination -- this is especially true when the failures are related to
concurrent usage and stress. The Log Trace Analyzer for Java Desktop (LTA-JD) is a
powerful tool for problem determination and analysis once the text logs are properly
extracted as Common Base Events. But what's the easiest way to extract, say, Java
Virtual Machine (JVM) logs from the WebSphere Application Server (WAS) so they can be used by the LTA-JD? This
article introduces the design of a custom static parser as a plugin for LTA-JD to
construct a meaningful, common language from the plain text WebSphere Application Server JVM logs.

Designing manageable resources with Apache Muse
Do you want to evolve from creating WSDM-compliant projects with Apache Muse to creating
WSDM-optimized projects? Any new user can use Apache Muse to design the Web
services interface for a manageable resource, generate the necessary Java code, and
build a deployable artifact with little thought towards the underpinnings of the Apache
Muse runtime. But if you are creating Web services to expose a large number of manageable resources or even just a single resource that is fairly complex, it pays to understand the core concepts behind the Muse programming model. Read this article, and the following tutorial, to
discover the core concepts that will take you from creating WSDM-compliant projects with
Muse to
creating WSDM-optimized projects with Muse.

Report Data Analyzer: Interpret EWLM performance data
As a workload manager (and not a capacity planning tool), the IBM Enterprise
Workload Manager focuses on real-time data and, thus, only retains performance data
covering the past 24 hours. There was a customer requirement, however, to have this data
available for later analysis. And so, the Data Hardening plug-in was added. This plug-in
allows on-the-fly dumping of performance data onto the file system. But, the
dumped data can't be directly exploited: Enter EWLM Report Data Analyzer.

Muse and WEF eases event reporting
The Web Services Distributed Management (WSDM) Event Format (WEF) is an OASIS standard that describes how to serialize events related to systems management in XML. The standard goes into detail about required values, optional values, and the semantics of both, but it offers no instruction for actually implementing the system. Fortunately, the Apache Muse project has an implementation of WEF that lets you create, send, and receive WEF events using a simple Java API. This article shows you how to handle these tasks from within an Apache Muse application.

Hit the ground running with AIDE, Part 7: Better IT management
The IBM Autonomic Integrated Development Environment (AIDE) facilitates a model-driven approach to touchpoint development, which is a useful, factory-style, wizard-assisted pattern for producing generic touchpoints. However, at some point in the AIDE-driven workflow, the touchpoint must be made specific to a given application. You can do this either at the model design stage or manually through hard-coding. In this tutorial -- the seventh in the series -- discover techniques for creating both generic and specific touchpoints, and learn how to produce touchpoints that have the right mixture for a given management application.

Calling Java classes from AME
The Autonomic Management Engine, a primary component of the IBM Autonomic Computing Toolkit, allows the use of JavaScript to define decision tree scripts that can be used for analysis, planning, and so on. Given that Java code is more powerful than JavaScript, it might be preferable to use Java code for creating the analysis components, whereas JavaScript might be suitable when simpler functionality is required. This article shows you how to call Java classes from the decision tree scripts as well as the associated setup. It also provides some guidance on issues that can potentially cause your decision tree scripts to fail and hints on what you can do to smoothly integrate Java code with the decision tree script.
