IBM SOA Foundation product integration: A complete ESB Gateway solution featuring WebSphere DataPower, Tivoli Access
Manager, and WebSphere Service Registry and Repository
Leveraging the concept of a service-oriented architecture usually brings
with it the ability to connect an increasing number of systems within an enterprise
-- but also across enterprises. While enabling a higher degree of automation and
reduced processing time, this also leads to growing concern about managing and
securing the underlying connections between heterogeneous IT systems. This article
describes how to address these concerns by implementing an ESB gateway using three
of the products within the IBM SOA Foundation platform, beginning with integrating
a IBM WebSphere DataPower SOA Appliance with IBM Tivoli Access Manager for security,
and then adding IBM WebSphere Service Registry and Repository for endpoint address
management.

Improve the run-time performance of the Generic Log Adapter, Part 2: A guide to writing efficient custom plug-ins
The Generic Log Adapter (GLA) is an important tool that can be used in autonomic computing systems to collect data from different data sources with many different formats. The performance of the GLA, which is typically used in problem determination, becomes critical to the performance of the entire autonomic computing system. Part 1 of this series took a look at an important dimension of the performance of the GLA, the performance of the rules that the GLA executes at run time. The GLA's performance is also affected by the performance of the individual components that are configured to execute the various functions of the Generic Log Adapter. This article looks at the performance aspects of these individual components as well as other general factors and configurations that influence the performance of the GLA. It also looks at the feature of running multiple contexts provided by the adapter and builds a custom outputter that can be shared among these contexts.

Improve the run-time performance of the Generic Log Adapter, Part 1: A guide to writing efficient rule sets
Data collection is an important aspect of autonomic computing problem determination and self-healing systems. Consequently, a performance bottleneck in data collection slows down the entire operation of the autonomic computing system. It also can be difficult to re-engineer because the data collection components are often built first. This article describes different techniques for writing efficient regular expressions that form the basis for rules in the Generic Log Adapter and discusses various issues with building custom plug-in components. By reducing the performance bottleneck at the lowest levels of granularity, it is possible to improve the run-time performance of the adapter over multiple operational cycles. This article also discusses other factors that might affect adapter performance and provides a guide for when you're designing rule sets and custom components for the Generic Log Adapter.

Introduction to cryptography, Part 3: Asymmetric cryptography
The security afforded by asymmetric cryptosystems depends on mathematical problems that are difficult to solve, such as factoring large integers into primes. Public key systems use two keys such that one key, the public key, can be used to encrypt some text that can then only be decrypted using the securely-held private key. Alternatively, the private key can be used to encrypt some information that anyone with access to the widely-available corresponding public key can decrypt, so satisfying themselves that the message was generated by the holder of the private key.

Automated System Recovery in Static IP environments using Tivoli Storage Manager
The current Tivoli Storage Manager Automated System Recovery Process supports Networks which supports DHCP. In networks that does not support DHCP and uses Static IP's,the local backup sets are used to recover these systems in case of a crash or total failure. In very large environments, servers cannot be ported on DHCP as the applications hosted in the servers are IP conscious. A typical example of such an environment would be a datacenter with multiple application servers that access the multiple database servers. In these environments, the servers are necessarily configured with static IP's. This article describes an Automated System Recovery process which facilitates system recovery in Static IP environments.

Autonomic Computing Expression Language
This tutorial shows how to use the Autonomic Computing Expression Language (ACEL), an XML-based expression language, to create an expression, parse it, prepare input for it, and evaluate it. ACEL was originally developed as a part of the Autonomic Computing Policy Language to describe conditions when a policy should be applied to a managed system. To learn more about how policies can be used to manage an IT system, download IBM Policy Management for Autonomic Computing (PMAC) from alphaWorks. However, ACEL is applicable in many other contexts such as specifying service level agreements, pricing, scheduling, and provisioning of services. In general, ACEL can be used to specify various types of expressions (numeric expression, Boolean expression, string expression, and so on) in XML documents.

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.

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.

Bulk attestation within Tivoli Identity Manager
As part of compliance requirements, organizations are required to perform attestation of a user's entitlements for access to systems. This process usually requires a responsible party (for example, the user's manager) to assert that the user continues to require access to a particular system. IBM Tivoli Identity Manager (ITIM) provides account attestation as part of its core functionality, and hence can implement complex attestation requirements. However, setting the attestation for a large number of target systems can be a chore. In addition, when a responsible party is asked to perform attestation for many users of a system as part of a continuous attestation cycle, the task becomes laborious. This tutorial gives the reader some methods for scaling attestation from a manageability perspective, using features available within ITIM 5.0.

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.

The autonomic computing edge: Can you CHOP up autonomic computing?
The autonomic computing architecture provides a foundation on which self-managing information technology systems can be built. Self-managing autonomic systems exhibit the characteristics of self-configuring, self-healing, self-optimizing, and self-protecting; these characteristics are sometimes described with the acronym CHOP. This article discusses the self-CHOP attributes and, in particular, explains why they are not independent of each other and how self-managing autonomic systems can integrate the CHOP functions.

Symptoms deep dive, Part 3: Classify your symptoms
To identify symptoms, a standard symptom taxonomy is an excellent starting point -- although it is not the only tool you need for this task -- because it provides a common framework with which symptoms authors can expand and promote the reuse of their individual symptoms in a more standardized way. This article introduces you to a standard taxonomy of autonomic computing symptoms used to categorize the types of situations described by the symptom. It also presents the methodology used for the identification of these categories, a methodology that also applies when new symptoms are discovered and when new categories need to be created or assigned to the symptoms. I'll also discuss some best practices for deciding whether a taxonomy needs to be extended.

Command line adapter for Tivoli Identity Manager
When using IBM Tivoli Identity Manager (ITIM) adapters, it often becomes necessary to execute an auxiliary function that is not provided ”ready to use” by the adapter. For example, when
provisioning an Active Directory (AD) account, there might be a need to create a default set of folders and files in the user's home directory. This paper discusses developing a custom ITIM adapter that allows these auxiliary functions to be implemented using shell commands. The paper also discusses the advantages of running this custom adapter over the use of postexec and preexec functions. It is assumed that the audience of this article is familiar with ITIM and Tivoli Directory Integrator (TDI).

The autonomic computing edge: Common Base Event Best Practices
Event-driven systems are an important part of enterprise IT management. The autonomic computing architecture defines an event representation called the Common Base Event that is the basis for the Web Services Distributed Management (WSDM) Event Format (or WEF). As the adoption rate of this event format races forward, IBM found it prudent to generate some best practices for its use; these best practices were published earlier this year. This article offers a perspective on those best practices and discusses their application in IT management systems.

Log files in action: Convert z/OS logs in a snap
Discover how to find z/OS log files and how to convert them to a format useful for autonomic computing components. Before log files can be used for such autonomic computing purposes as problem determination, they must be in a common language (such as the Common Base Event format). Not only can binary-format z/OS logs not be used by autonomic computing systems in their native state, they are often difficult to locate. This article explains how to find and convert z/OS logs to a text format, rendering them useful for autonomic computing components.

Create GLA components using Release 2 of the Autonomic Computing Toolkit
The Generic Log Adapter (GLA) lets you to process log files and transform their contents into events that follow the Common Base Event (CBE) format. Internally, the GLA consists of a chain of components that have different roles in the transformation process. The last member in the chain is the outputter, the component that externalizes a CBE instance generated by the GLA. Typical destinations for CBE instances include the console, a file, or an autonomic computing log agent, and the GLA ships with outputters for each of these destinations. However, your specific needs might not be addressed by the standard GLA outputters. This tutorial shows you how to write custom outputters. By following the same general pattern you can write any type of GLA component.

Create a problem determination scenario from scratch
This tutorial chronicles the building of an autonomic computing system that monitors a Java application to demonstrate the ability to detect and resolve issues within the system, a problem determination scenario. In the autonomic computing world, a problem determination scenario is one in which you can demonstrate how an overall system can detect, diagnose, and resolve problems. The Problem Determination Scenario, which you can download from the developerWorks Autonomic computing content area, is an example of a system that does just that by showing you how you can use the various pieces of the Autonomic Computing Toolkit together. In this tutorial, you can follow along and create each piece of our own simple problem determination scenario, which will give you an in-depth understanding of key autonomic computing concepts by using the Generic Log Adapter Runtime and Rule sets, the Resource Model Builder, and the Autonomic Management Engine.
