Integrating WebSphere Message Broker with IBM Business Process Manager

This from my IBM UK colleague ( and fellow bon viveur ), Paul Smith, with whom I've shared mainly a fine Hursley Park club-house breakfast: -


This article shows you how to integrate WebSphere Message Broker with IBM Business Process Manager Standard Edition, with pragmatic ways to get the two products working together at both design time and run time.

This article describes the integration of IBM® WebSphere® Message Broker (hereafter called Message Broker) with IBM Business Process Manager Standard Edition (hereafter called IBM BPM) . Because Message Broker V8.0.0.1 is going to change the way in which services are created, this article focuses on bottom-up scenarios for the time being. As soon as Message Broker Fix Pack 1 is available, the top-down scenarios can be completed.

This article describes pragmatic ways to get the two products to work together from both design-time and run-time perspectives. For design time, integration involves methods that will make the different tools look more or less aligned. The key deliverable is to make the tools look like they work together in an aligned way so that you can easily do demo's, pilots, and proofs-of-concept (PoCs).

The article focuses on out-of-the-box features, even though many utilities have been developed to extend Message Broker capabilities. The article does not cover development governance, impact analysis, or changes to existing implementations, which will need to be addressed in the future. Also, the article covers only web service integration between the two products, and leaves JMS and MQ integration for a future article.

WebSphere Application Server 8.5.5 - High Performance Extensible Logging (HPEL)

IBM WebSphere Application Server V8.5 enhances the High Performance Extensible Logging (HPEL) feature that was first introduced in V8.0.

As the name suggests, HPEL was created to significantly outperform the existing application server logging and tracing mechanism
plus provide a powerful way to extend log and trace entries with extra fields.

Beyond that, HPEL provides a number of ease of use improvements for working with log and trace content.

Enabling HPEL is quick and easy, and does not require any code changes to your applications.

HPEL is a new log and trace content storage and access system for WebSphere Application Server. HPEL stores log and trace content produced by the existing log and trace APIs, in particular the java.util.logging API.

HPEL addressses a number of common needs:
  • Log and trace performance
  • Log and trace entry extensibility
  • Automating log/trace analysis
  • Application separation
  • Request tracking
  • Remote access to logs/trace

In short, HPEL moves away from the traditional WAS logging mechanism - SystemOut.log, SystemErr.log etc. - and creates a log repository, and a potentially much better way to interact with the logs, either via a GUI ( part of the Integrated Solutions Console ) or a command-line tool ( see below for both examples ).

This is how HPEL looks: -


This is how one configures HPEL: -


and this is how one uses the LogViewer tool in the event that one doesn't like a GUI :-)

IBM Redpaper - WebSphere MQ Primer: An Introduction to Messaging and WebSphere MQ

I've just finished this nice little ( 64 real pages ) book on the iPad, and would recommend it to anyone wishing to learn a bit about WebSphere MQ.

It's written against the version 7.X codebase, but should still be relevant to version 8. It makes brief reference to WebSphere Message Broker ( now IBM Integration Bus ) and WebSphere Application Server ( JMS etc. ), and does provide a few examples to create Queue Managers, Queues, send/receive messages in C and Java etc.

Definitely worth a read: -

Adding WAS as a Unix service

This came up in a conversation during a WAS 8.5.5 enablement session today.

It is possible to register and run a WAS server as a service on Linux.

This is how: -

$ /opt/IBM/WebSphere/AppServer/bin/wasservice.sh

CWSFU0010I: Usage: wasservice [options]
options:
[-start] <service name>
-add <service name>
-serverName <server name>
-profilePath <service profile directory>
[-wasHome <install root>]
[-userid <user id>]
[-startArgs <additional startServer parameters>]
[-stopArgs <additional stopServer parameters>]
-remove <service name>
-stop <service name>
-status <service name>


$ /opt/IBM/WebSphere/AppServer/bin/wasservice.sh -add foobar -serverName dmgr -profilePath /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/

Interestingly, the service name foobar gets "renamed" to foobar_was.init as evidenced here: -

$ls -altrc /etc/init.d/

-rwxr-xr-x   1 root root  1938 Jun 23 16:51 irqbalance
-rwxr-xr-x   1 root root  2571 Jun 23 16:51 mdmonitor
-rwxr-xr-x   1 root root  9980 Jun 24 13:30 jexec
drwxr-xr-x.  2 root root  4096 Jun 24 15:20 .
-rwx--x--x   1 root root  3335 Jun 24 15:20 foobar_was.init


and: -

$ chkconfig --list | grep -i foobar

foobar_was.init 0:off 1:off 2:on 3:on 4:on 5:on 6:off

I can now manage the server using standard Linux commands e.g.

$ service foobar_was.init start

Starting WebSphere Application Server - dmgr ...
ADMU0116I: Tool information is being logged in file
           /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/logs/dmgr/startServer.log
ADMU0128I: Starting tool with the Dmgr01 profile
ADMU3100I: Reading configuration for server: dmgr
ADMU3200I: Server launched. Waiting for initialization status.
ADMU3000I: Server dmgr open for e-business; process id is 54588

$ service foobar_was.init status

WebSphere Application Server - dmgr is running.

$ service foobar_was.init stop

Stopping WebSphere Application Server - dmgr ...
ADMU0116I: Tool information is being logged in file
           /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/logs/dmgr/stopServer.log
ADMU0128I: Starting tool with the Dmgr01 profile
ADMU3100I: Reading configuration for server: dmgr
Realm/Cell Name: <default>
Username: wasadmin
Password:       
 ADMU3201I: Server stop request issued. Waiting for stop status.
ADMU4000I: Server dmgr stop completed.

 
*UPDATE*
 
One thing that I realised after the event was that I'd neglected to specify the -userid parameter on the wasservice command, meaning that, when I started the Deployment Manager, it automatically started as root, rather than the required wasadmin.

This led to some problems when I tried to access the admin. console, where certain elements were completely blanked out, and I saw: -

...
[6/24/14 19:42:06:622 BST] 0000011d WorkSpaceMast E WKSP0012E: Exception while extracting cells/bpm85Cell/nodes/bpm85Node1/servers/dmgr/server.xml from ConfigRepository--com.ibm.websphere.management.exception.DocumentIOException: Unable to create temp file for document: cells/bpm85Cell/nodes/bpm85Node1/servers/dmgr/server.xml

...

in the logs.

I validated this by inspecting the generated script - foobar_was.init - which contained: -

...
# *** THE FOLLOWING BLOCK IS PROGRAMMATICALLY MAINTAINED. ***
# *** PLEASE ALTER ONLY VIA THE WASSERVICE TOOL. ***
# START BLOCK
SERVERNAME="dmgr"
PROFILEPATH="/opt/IBM/WebSphere/AppServer/profiles/Dmgr01"
WASHOME="/opt/IBM/WebSphere/AppServer"
STARTARGS=""
STOPARGS=""
SERVICENAME="foobar_was.init"
RUNASUSER=
# END BLOCK
...

I fixed this by removing the service / script: -

$ /opt/IBM/WebSphere/AppServer/bin/wasservice.sh -remove foobar

and then recreated it as follows: -

$ /opt/IBM/WebSphere/AppServer/bin/wasservice.sh -add foobar -serverName dmgr -profilePath /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/ -userid wasadmin

which changed the foobar_was.init script: -

...
# *** THE FOLLOWING BLOCK IS PROGRAMMATICALLY MAINTAINED. ***
# *** PLEASE ALTER ONLY VIA THE WASSERVICE TOOL. ***
# START BLOCK
SERVERNAME="dmgr"
PROFILEPATH="/opt/IBM/WebSphere/AppServer/profiles/Dmgr01"
WASHOME="/opt/IBM/WebSphere/AppServer"
STARTARGS=""
STOPARGS=""
SERVICENAME="foobar_was.init"
RUNASUSER="wasadmin"
# END BLOCK
...
 
which now works as expected.

Installing and Using Oracle Java7 on Red Hat Enterprise Linux

So, having downloaded the latest Oracle JRE from here: -


I wanted to set it as the default JVM on my Red Hat Enterprise Linux Server release 6.5 (Santiago) box ( instead of the stock OpenJDK JVM ): -

$ java -version

Saving time with IBM Monitoring and Diagnostic Tools - By Mr John Pape Esq

From Mr John Pape Esq: -

As a member of the IBM WebSphere foundation SWAT team, my daily job typically revolves around solving problems that customers run into using IBM software such as WebSphere Application Server and WebSphere eXtreme Scale. Much of the time I'm working out what diagnostic material is needed to draw the inferences and conclusions into the light so an actionable resolution can be put in place.

From the pen of Eric Herness - BAM, IBM Business Monitor and Continuous Process Improvement

Customers often ask me why they need BAM, in the case of the IBM Smarter Process Portfolio, why do they need IBM Business Monitor.    The answer is a bit complex, but offers a key lesson about business process management in general.  This blog post will begin to tell this story and leave some room for interpretation and discussion.

Samsung TV - When YouTube becomes NoTube

So my bro-in-law has a rather shiny 46" Samsung D6530 3D TV, with which I was so impressed I bought a similar model ( albeit only the 2D version as I don't have Sky, BluRay or a passion for foolball ).

One thing that made him sad was that the native YouTube app failed to work - it'd just hang there, and never actually get past the logo.

A quick Google later, and I suggested that the firmware might need to be updated.

He was on 001006, and 001026 appears to be the current version.

I downloaded it from here, as a ~120 MB .EXE file: -


extracted it to a USB thumb-drive ( using a Windows VM on my Mac ), and then used the Samsung's menu to update the firmware from the USB key.

Once updated, we're in like Flynn, and YouTube is pushing ABBA out across the lounge .....

So IBM ODM 8.6 was released last week - Friday 6 June

More on Java and Canonical Hostnames

Following up on my earlier post: -


I've refined my Java class - hostStuff.java: -

import java.net.InetAddress;
import java.net.UnknownHostException;

public class hostStuff
{
public static void main(String[] args)
{

try
{
InetAddress address = InetAddress.getLocalHost();
System.out.println("My IP address ( via InetAddress.getLocalHost() ) is " + address.toString());
System.out.println("My hostname ( via InetAddress.getHostName() ) is " + address.getHostName());
System.out.println("My hostname ( via InetAddress.getCanonicalHostname() ) is  " + address.getCanonicalHostName());
}
catch (UnknownHostException e)
{
       System.out.println("I'm sorry. I don't know my own name.");
}
}
}


The class does the following things: -

Get the localhost's IP address InetAddress address = InetAddress.getLocalHost();
Report the IP address System.out.println("My IP address ( via InetAddress.getLocalHost() ) is " + address.toString());
Get the hostname for this IP address System.out.println("My hostname ( via InetAddress.getHostName() ) is " + address.getHostName());
Get the Canonical ( fully qualified ) hostname for this IP address System.out.println("My hostname ( via InetAddress.getCanonicalHostname() ) is  " + address.getCanonicalHostName());

My next trick is to write a class that iterates through ALL of the known IP addresses ( many boxes have multiple Network Interface Cards and, therefore, many addresses ) and report on the hostnames for each.

The rationale behind this is where one configures Kerberos/SPNEGO using the Canonical hostname of a server - it's important to know WHAT the fully qualified hostname is, and to ensure that DNS can return a valid hostname for an IP address, as well as a valid IP address for a hostname.

Here's some examples: -

Red Hat Enterprise Linux running on IBM PureApplication System

$ java hostStuff
My IP address ( via InetAddress.getLocalHost() ) is vm-004-039/10.34.4.39
My hostname ( via InetAddress.getHostName() ) is vm-004-039
My hostname ( via InetAddress.getCanonicalHostname() ) is  vm-004-039.hurpas01.ipas.hursley.ibm.com

Mac OS X

$ java hostStuff
My IP address ( via InetAddress.getLocalHost() ) is DMHMBP.local/10.61.32.78
My hostname ( via InetAddress.getHostName() ) is DMHMBP.local
My hostname ( via InetAddress.getCanonicalHostname() ) is  10.61.32.78


Red Hat Enterprise Linux running on VMware

$ java hostStuff
My IP address ( via InetAddress.getLocalHost() ) is rhel6.uk.ibm.com/127.0.0.1
My hostname ( via InetAddress.getHostName() ) is rhel6.uk.ibm.com
My hostname ( via InetAddress.getCanonicalHostname() ) is  localhost

Of the three, only the IPAS environment is "properly" configured, in that InetAddress.getCanonicalHostname() returns the fully qualified host/domain name of the server.

Engage Business Users in Process Improvement with IBM Blueworks Live

More from IBM about the benefits of IBM Blueworks Live

...
A critical success factor in any business process improvement project is engaging business users. They are, after all, the ones who know best how the current-state process works, as well as the various ways in which it doesn't work. And they are also the ones whose daily work life will be most directly impacted by any process changes. The trick is getting business users directly engaged in the project. They are used to that being "IT's job," although they often complain that IT doesn't listen to their requirements, or at least does not adequately understand them. But if you can somehow get those users to actively collaborate with your business analysts and consultants in documenting the current process, analyzing its shortcomings, and describing in detail a proposed new and better process, your chances of successful process improvement significantly increase. That requires new tools that not only eliminate the barriers that have always gotten in the way of business users but encourage active business user participation in the project.

From the field - Lean and BPM: Two peas in a pod ?

From my IBM UK colleague, Sunil Aggarwal, comes this rather useful post about IBM BPM and lean techniques: -

...
Recently I have seen a resurgence of customers adopting lean techniques in their projects. In general, these have been very successful due to speed of delivery, quality of deliverables and output, and the ability to drive fundamental change to the business process being implemented. The result is significant and can offer quantitative cost reduction.

Updating IBM Installation Manager via the command-line

So this ties up with a piece of work that a colleague is undertaking on the IBM PureApplication System.

As part of his work, he needs to update IBM Installation Manager (IIM) in place from 1.6.2 to 1.7.2

Here's the process: -

Before

$ /opt/IBM/InstallationManager/eclipse/tools/imcl listInstalledPackages

com.ibm.cic.agent_1.6.2000.20130301_2248
com.ibm.bpm.ADV.v85_8.5.1.20131107_1830
com.ibm.websphere.ND.v85_8.5.5001.20131018_2242

During

$ /tmp/foobar/userinstc -acceptLicense -dataLocation /home/wasadmin/var/ibm/InstallationManager/

Updated to com.ibm.cic.agent_1.7.2000.20140227_0303 in the /opt/IBM/InstallationManager/eclipse directory.

After

$ /opt/IBM/InstallationManager/eclipse/tools/imcl listInstalledPackages

com.ibm.cic.agent_1.7.2000.20140227_0303
com.ibm.bpm.ADV.v85_8.5.1.20131107_1830
com.ibm.websphere.ND.v85_8.5.5001.20131018_2242

The pre-requisite is that one must have IIM 1.7.2 downloaded from here and unpacked into /tmp/foobar.

WebSphere Application Server - Monitoring for performance - IBM Monitoring and Diagnostic Tools for Java - Health Center

Added to my other post: -


we also have this tool: -


The IBM Monitoring and Diagnostic Tools for Java - Health Center is a free low-overhead diagnostic tool and API for monitoring an application running on an IBM Java Virtual Machine.

The IBM Monitoring and Diagnostic Tools for Java - Health Center (Health Center) enables you to assess the current status of a running Java application. Health Center continuous monitoring provides information to identify and help resolve problems with your application:

• Identify if native or heap memory is leaking
• Discover which methods are taking most time to run
• Pin down I/O bottlenecks
• Visualize and tune garbage collection
• View any lock contentions
• Analyse unusual WebSphere® Real Time events
• Monitor your applications Thread activity
• Detect deadlock conditions in your application
• Gather class histogram data
Use Health Center to help you:

• Optimize application performance
• Improve application stability and uptime
• Reduce system resource usage
• Reduce the time to resolve problems
• Drive down development and maintenance costs
• Trigger System dumps for analysis in IBM Monitoring and Diagnostics Tools for Java Memory Analyser
• Turn on verbosegc collection for analysis in IBM Monitoring and Diagnostics Tools for Java Garbage Collection and Memory Visualizer


Now I've only briefly played with this, during a day-long session with the excellent Java Technology Centre team from IBM Hursley Park.

However, I've already used the Health Center client ( the GUI part of it ) running natively on my Mac (!) against WebSphere Application Server Network Deployment running on Red Hat Enterprise Linux.

I'll write a post about this in due course, but Health Center is definitely going to be in my kit-bag going forward ......

WebSphere Application Server - Monitoring for performance - IBM Application Performance Diagnostics

So I need to write this up more fully, but I've been brought up-to-speed with two rather useful tools to facilitate the monitoring of WebSphere Application Server ( and other Java workloads ): -


IBM Application Performance Diagnostics (APD) is a powerful yet lightweight tool that can be deployed quickly to help optimize the performance of your WebSphere Application Server and WebSphere Portal applications.

What it does for you

Adoption Scenarios for IBM PureApplication System

In my role as Capability Lead for Cloud and Infrastructure, I'm frequently looking at opportunities where IBM PureApplication System (IPAS) can be of use to my clients, either as an on-premise appliance or, more recently, made available via the IBM SoftLayer cloud hosting platform.
