Anatomy of the application server JVM in WebSphere Application Server

Sometimes servers do not start. Maybe it is due to a bad build, the configuration has gotten corrupted, or it just stopped working. This blog helps you understand the anatomy of the Application Server start up process. It provides you with troubleshooting and debugging techniques to determine why the server is not starting or why the server is not stopping.

Extending IBM Business Process Manager to the Mobile Enterprise with IBM Worklight

This redbook was published a few weeks back: -

Extending IBM Business Process Manager to the Mobile Enterprise with IBM Worklight

In today's business in motion environments, workers expect to be connected to their critical business processes while on-the-go. It is imperative to deliver more meaningful user engagements by extending business processes to the mobile working environments.

This IBM® Redbooks® publication provides an overview of the market forces that push organizations to reinvent their process with Mobile in mind. It describes IBM Mobile Smarter Process and explains how the capabilities provided by the offering help organizations to mobile-enable their processes.

This book outlines an approach that organizations can use to identify where within the organization mobile technologies can offer the greatest benefits. It provides a high-level overview of the IBM Business Process Manager and IBM Worklight® features that can be leveraged to mobile-enable processes and accelerate the adoption of mobile technologies, improving time-to-value. Key IBM Worklight and IBM Business Process Manager capabilities are showcased in the examples included in this book. The examples show how to integrate with IBM Bluemix™ as the platform to implement various supporting processes.

This IBM Redbooks publication discusses architectural patterns for exposing business processes to mobile environments. It includes an overview of the IBM MobileFirst reference architecture and deployment considerations.

Through use cases and usage scenarios, this book explains how to build and deliver a business process using IBM Business Process Manager and how to develop a mobile app that enables remote users to interact with the business process while on-the-go, using the IBM Worklight Platform.

IBM Operational Decision Manager 8.7 - Overcoming an earlier issue with duplicate JDBC data sources

This problem has been nagging me for a few months, since first I installed IBM Operational Decision Manager (ODM) 8.5 for a client.

In brief, I was finding that the following exception: -

 [wsadmin] WASX7017E: Exception received while running file "/opt/ibm/WebSphereProfiles/ODMCell1Dmgr01/bin/rules/configureDSRulesNetworkDeployer.py"; exception information: com.ibm.websphere.management.exception.ConfigServiceException: ADMG0037E: A new instance of the DataSource object cannot be created because the jndiName attribute of an existing DataSource object has the same value as jdbc/resdatasource.

The additional pair of datasources turn up after the WAS profiles are created, and after the node(s) are federated into the cell.

The temporary solution is to delete jdbc/resdatasource ( one for each node ) via ISC *BEFORE* running the configureDSCluster.sh script.

However, I was looking for a more permanent solution, especially as I experienced the same issue with ODM 8.7 today.

I dug around inside IBM Support, and found the solution ...

It was the way that I was building the environment.

Briefly, I was creating the Deployment Manager and Node profiles, using manageprofiles against the profile templates for DM: -

/opt/ibm/WebSphere/AppServer/profileTemplates/rules/management/ds/

and Managed Node: -

/opt/IBM/WebSphere/AppServer/profileTemplates/rules/

This was part of the problem :-)

I need to play with this further, but I was able to overcome the issue by creating "bog standard" profiles for DM and Node, using the out-of-the-box templates, creating the WAS cell ( federating the nodes into the cell ), and then augmenting the Deployment Manager profile with the ODM template.

I'm going to write this up as a separate blog post shortly.

Bottom line, it's all in the profile templates, mate :-)

IBM Business Process Manager V8.5 Performance Tuning and Best Practices

Published last month: -

This IBM® Redbooks® publication provides performance tuning tips and best practices for IBM Business Process Manager (IBM BPM) V8.5.5 (all editions) and IBM Business Monitor V8.5.5. These products represent an integrated development and runtime environment based on a key set of service-oriented architecture (SOA) and business process management (BPM) technologies. Such technologies include Service Component Architecture (SCA), Service Data Object (SDO), Business Process Execution Language (BPEL) for web services, and Business Processing Modeling Notation (BPMN).

Both IBM Business Process Manager and Business Monitor build on the core capabilities of the IBM WebSphere® Application Server infrastructure. As a result, Business Process Manager solutions benefit from tuning, configuration, and best practices information for WebSphere Application Server and the corresponding platform Java virtual machines (JVMs).

This book targets a wide variety of groups, both within IBM (development, services, technical sales, and others) and customers. For customers who are either considering or are in the early stages of implementing a solution incorporating Business Process Manager and Business Monitor, this document proves a useful reference. The book is useful both in terms of best practices during application development and deployment and as a reference for setup, tuning, and configuration information.

This book talks about many issues that can influence performance of each product and can serve as a guide for making rational first choices in terms of configuration and performance settings. Similarly, customers who already implemented a solution with these products can use the information presented here to gain insight into how their overall integrated solution performance can be improved.
