IBM BPM Standard 7.5.1.1 - Problem importing snapshots into a Process Server

So I've been doing a lot of work with BPM snapshots and scripting recently.

This time around I was looking to install a snapshot to an offline Process Server, as follows: -

$ cd /opt/IBM/WAS/wasadmin1/app/profiles/dmgr/bin
$ ./wsadmin.sh -host processserver.uk.ibm.com -port 43003 -user tw_admin -password passw0rd -lang jython -p /home/wasadmin1/davehay_soap_override.props
wsadmin> AdminTask.BPMInstallOfflinePackage('[-inputFile /home/wasadmin1/LR2R3_1.zip]')

 which (sadly) failed with: -

WASX7015E: Exception running command: "AdminTask.BPMInstallOfflinePackage('[-inputFile /home/wasadmin1/LendingR2R3.twx]')"; exception information:
java.lang.Exception: java.lang.Exception: java.lang.NullPointerException

Want to know what was wrong ?

I was trying to install the actual TWX file, rather than the ZIP file that contains the TWX file ( as generated by BPMCreateOfflinePackage and BPMExtractOfflinePackage ).

What a muppet :-)

Updating WAS JDBC Data Source Passwords - Don't forget to reboot

In the words of The IT Crowd ( back on for a final time on September 27 ), "Have you tried turning it off and on again?".

As part of a normal password expiration process, we needed to update the JDBC Data Source passwords ( actually, the Java2 Authentication Aliases = J2C Aliases ) for a BPM Standard 7.5.1Process Server installation.

Having changed the passwords, remembering to add a comment indicating when and who, I tested the JDBC data sources, which immediately failed with: -

The test connection operation failed for data source LocalZoneDB on server nodeagent at node gbrdsr000000918_base with the following exception: java.sql.SQLException: [jcc][t4][2013][11249][3.61.65] Connection authorization failure occurred. Reason: User ID or Password invalid. ERRORCODE=-4214, SQLSTATE=28000DSRA0010E: SQL State = 28000, Error Code = -4,214. View JVM logs for further details.

The test connection operation failed for data source LocalZoneDB on server nodeagent at node gbrdsr000000917_base with the following exception: java.sql.SQLException: [jcc][t4][2013][11249][3.61.65] Connection authorization failure occurred. Reason: User ID or Password invalid. ERRORCODE=-4214, SQLSTATE=28000DSRA0010E: SQL State = 28000, Error Code = -4,214. View JVM logs for further details.

Hmmm, I thought - what have I missed ?

Initially, I restarted the Deployment Manager ( from where I was running the Test Connection ), but to no avail.

I then checked and rechecked the passwords that I'd entered via the Integrated Solutions Console GUI, by comparing them to the encoded passwords here: -

/opt/IBM/WAS/wasadmin1/app/profiles/dmgr/config/cells/ProcServ02Cell/security.xml

and confirmed that they were all exactly as I'd intended to enter them.

I then asked the DBA to validate the passwords; again, they worked perfectly ( he was testing from the DB2 server using su - for the respective user ID ).

Finally ……

I restarted the Node Agents :-)

And…. guess what ….. ?

It worked.

Why, I hear you cry ?

Because the JDBC Data Source Test Connection process, whilst initiated by the Deployment Manager, actually runs in the Node Agent JVM, hence the need for the restart :-)

Book Review - Shortcuts to Success: Project Management in the Real World - Second Edition

September 23, 2013, 11:08 am

This is the second edition of Elizabeth Harrin's excellent book on project management, the first of which I read a few years back.

Whilst I've never been interested in switching disciplines per se, I find it useful to maintain a working knowledge of the Project Management profession, especially as I've worked with so many good PMs over the years, most recently since I've worked in SWG Services.

This is the second PM book that I've reviewed in the past few months, with John Turner's A Project in your Pocket here on the blog back in July.

In Shortcuts to Success, Elizabeth has provided a really useful cookbook for PMs of all levels, whether new to the profession, or experienced practitioners.

This is a relatively short book - ~200 pages - and is chock-full of references, case studies and quotations. Each short chapter is clear and concise, focusing on a specific area of the discipline. It's not quite pocket-sized, but I'm absolutely certain that there's an ebook version for the ebook readers out there.

The covers all the important aspects of project management, from budgeting, through scope and people management, to teaming, collaboration and documentation.

As you can imagine, with my background in collaboration, some of my favourite chapters include those that focus on mentoring, matrix management, collaborative document management, and experience sharing.

Each chapter includes one or more case studies, hence the "real world" title, which are used to illustrate the particular point that Elizabeth is seeking to make.

The book is clearly based upon experience, both of the author and the contributors, which makes it a useful reference into which anyone involved in project delivery can, and, in my view, should, dip.

I strongly recommend this book to anyone working in a project delivery role, regardless of age, discipline and experience.

IBM Connections 4 - SPNEGO ain't working

September 24, 2013, 9:56 am

This was a blast from the past for me, having been away from IBM Connections and WebSphere Portal for nearly a year.

I took a call from a customer with whom I worked in 2010-12, who was finding that SPNEGO-based Single Sign-On was NOT working for IBM Connections 4, even though it WAS working for WebSphere Portal 8, both of which run on WAS 8, and use the same Active Directory infrastructure.

In essence, they accessed any protected URL in Connections, but found that the HTTP 401 Authenticate/Negotiate response was never issued.

I made a few suggestions on the call, including referencing back to my Connections/SPNEGO/AD presentation: -


including enabling tracing to see what's going on.

I also raised a question about DNS and reverse lookups ( IP addresses to hostnames ) as I know that had caused a problem in the past.

Later in the day, I received an email from my customer, with some good news - he'd fixed it, and it's all now working.

They enabled tracing, and could see the following in the logs: -

[24/09/13 14:23:17:458 BST] 00000081 WebAuthentica <  handleSSO: (null) Exit
[24/09/13 14:23:17:458 BST] 00000081 WebAuthentica 3   handleSpnegoWebAuthentication was skipped.

which made no sense, as the URL was definitely protected, and yet they were falling back to the fallback login page: - 

[24/09/13 14:23:17:458 BST] 00000081 WebAuthentica >  handleCustomLogin Entry
[24/09/13 14:23:17:458 BST] 00000081 WebAuthentica 3   Form based login is configured for the resource
[24/09/13 14:23:17:458 BST] 00000081 WebAuthentica >  getFormURL Entry

When they accessed an unprotected URL ( one not being protected by SPNEGO ), they could see a log entry acknowledging that the URL was to be skipped.

They then removed all of the SPNEGO filters e.g.

request-url!=noSPNEGO;
request-url!=/mobile;
request-url!=/nav;
request-url!=/bundles/js;
request-url!=/static

 validating them by reformatting the list in Notepad, and then identified the problem - they had: -

requesturl

rather than: -

request-url

:-)

Thanks to Dave and his team for sharing the problem and, better still, the solution :-)

IBM Business Process Manager (BPM) and IBM Application Performance Management (APM) - Made To Go Together

September 27, 2013, 12:05 pm

One of my IBM UK colleagues gave us an excellent overview of IBM's Application Performance Management (APM) solution, particularly in the context of IBM BPM.

Application Performance Management (APM) provides enhanced visibility specifically into application performance.

With Application Performance Management, you can:

• Detect performance problems quickly enough to minimize, or preclude business impact via integrated capabilities.
• Simplify operations management to cost effectively manage the complete IT and network infrastructure.
• Monitor end-user experience to identify and remediate problems before users are impacted.


As I say, we were specifically interested in APM in the context of BPM, as illustrated by this excellent developerWorks article: -


IBM Business Process Manager (BPM) optimizes critical business processes - you cannot afford for those critical processes to go down or perform poorly. With increasingly complex, dynamic IT infrastructures, ensuring continuous availability and peak performance is increasingly difficult. IBM has the tools you need to ensure the optimized performance of your BPM solution and its underlying IT infrastructure.
The IBM Business Process Manager (BPM) and IBM SmartCloud Application Performance Management (SmartCloud APM) teams have delivered a new BPM monitoring solution that is available now in both SmartCloud APM v7.6 and ITCAM for Applications v7.2.

BPM performance problems or process failures can be the result of business level problems or IT resource problems. An existing BPM monitoring solution - IBM Business Monitor - provides monitoring related to the business efficiency and effectiveness of the process itself. It focuses on giving real time visibility into the results of the business processes.

The new SmartCloud APM 7.6 monitoring solution extends IBM's BPM monitoring support by focusing on the IT infrastructure that is supporting these business processes. If a problem is identified, you have the information that you need to identify the change you need to make to the infrastructure to ensure the availability and performance of business processes.

My colleague, Stephen, also made reference to this rather lovely APM demo site: -


Go on, have a play.

Let me know if you need to know more.

Managing Snapshot Deactivation in IBM BPM 7.5.1.1

October 3, 2013, 10:36 pm

In IBM BPM 7.5.1.1 ( Fixpack 1 ), the behaviour of the Deactivate Snapshot command / process has changed.

By default, any running instances will be, effectively, locked, so that they can no longer be used, although they won't actually be terminated.

This is the default for 7.5.1.1, whereas, apparently, in BPM 8.X, the default behaviour is back to the former i.e. active snapshot instances will continue to be usable, although ( of course ) new instances cannot be started.

The behaviour can be reversed, by adding two lines into 100Custom.xml, and restarting the AppTarget cluster: -

<block-deactivated-snapshot-favorite-progression merge="replace">false</block-deactivated-snapshot-favorite-progression>
<block-deactivated-snapshot-task-progression merge="replace">false</block-deactivated-snapshot-task-progression>

Note that it is vital to add merge="replace" or the setting will stay set to true which isn't cool :-)

This Technote ( for WLE 7.2.0.4 ) provides more detail on the change: -


Having changed the default behaviour, I can now continue to progress instances for deactivated snapshots, although ( of course ) I cannot spawn new instances.

However, I'd NOT given the user the Operator role.

Monitoring and tuning a BPM platform at the system level is far away from getting process tracking points data and build nice scoreboards showing the process performance. But at the end if the system doesn't perform well the users will complain about how it's affecting their performance and how that is impacting the process SLAs.  And if that happens the BPM "system" will be seen as the reason for the bad business performance. Besides all that no one likes to use a system that is slow and has bad responsiveness.

IBM BPM - What is the Performance Data Warehouse ?

October 15, 2013, 7:33 am

Here's an introduction to PDW from Neil Kolban: -

The Performance Data Warehouse is a database responsible for collecting and managing data originated by Process Server instances. Think of this as the repository for information about the history of the system as is used for reporting of the outcome of processes. The sourcing of data for reporting comes from the single Performance Data Warehouse database which may be associated with multiple Process Server instances. This architecture allows aggregation of information from multiple servers to be achieved. Since generation of reporting knowledge can be computationally expensive, the separation of the Process Servers from the Performance Data Warehouse also allows for reports to be generated without impacting the operation of running processes.

and here's what the BPM documentation says: -

In Process Designer, define the variables that you want to track and then send tracking definitions to the Business Performance Data Warehouse.

The Business Performance Data Warehouse creates a database table to hold the tracked data.

Run instances of your processes on the Process Center Server or a Process Server in a runtime environment.

The Business Performance Data Warehouse retrieves tracked data for each variable from the Process Center Server or Process Server at regular intervals.

Create reports in the Designer that query the Performance Data Warehouse to retrieve the required data.

Reports that you define in the Designer display as scoreboards in Process Portal or a customized portal.

You can also query the Performance Data Warehouse from third-party tools like Microsoft Access to generate reports.

WebSphere Application Server JVMs - Dumping

Thanks to my mate, Mike, for this.

<caveat emptor>

Want to force a WAS JVM ( or, almost certainly, any other JVM ) to generate a core dump ( Javacore ) ?

Using Unix ?

If so, identify the Process ID ( PID ) of the JVM, perhaps using ps auxw | grep -i java and then, once you've checked AND double-checked that it's the right PID, issue this command: -

$ kill -3 12345

( where 12345 is an example of the PID )

The Javacore will be, by default, written to the WAS profile root e.g. /opt/IBM/WebSphere/AppServer/profiles/AppSrv01.

Want to force a heap dump ?

If so, fire up wsadmin: -

$ cd /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/bin
$ ./wsadmin.sh -lang jacl

wsadmin> set objectName [$AdminControl queryNames WebSphere:type=JVM,process=<JVM Name>,node=<Node Name>,*] 

which returns something like this: -
 
WebSphere:name=JVM,process=bpmPCapp01-server01,platform=proxy,node=primary_base,j2eeType=JVM,J2EEServer=base-bpmPCapp01-server01,version=7.0.0.25,type=JVM,mbeanIdentifier=JVM,cell=ProcCtr03Cell,spec=1.0

wsadmin> $AdminControl invoke $objectName generateHeapDump

Again, the heap dump  will be, by default, written to the WAS profile root e.g. /opt/IBM/WebSphere/AppServer/profiles/AppSrv01. 

</caveat emptor>

Interestingly, we saw this self-same issue in one of our BPM Standard 7.5.1.1 environments last week: -

Abstract

In IBM Business Process Manager V7.5.x and 8.0.x products, there is an intermittent issue that causes the wrong trust store to be used for SSL connections. This siutuation leads to different types of communication errors between servers.

Content

The communications errors continue until the affected server is restarted. This issue does not occur frequently. However, it has a high impact when it occurs. It is more likely that you might see this issue with IBM Business Process Manager V7.5.x, but it can also occur with Version 8.0. Due to the impact of this issue, you should apply the interim fix for APAR JR46822, which is available in Fix Central. For more information about the issue, see JR46822.

The fix is included in IBM Business Process Manager V8.5.

In this tutorial, you will use the tools in IBM® Process Designer to re-create the packaged Hiring Sample process application that is in IBM Process Center.

This tutorial gets you started with aspects of the Process Designer tool by having you iteratively model and test a hiring process instance. As you complete the lessons, you will learn about Process Designer so that you can build your own processes.

Note: This tutorial is a learning exercise that describes one way of modeling, implementing, and testing a process. Depending on your process and process application, other techniques might be more appropriate.

This tutorial is broken down into the following five modules:

• Model the process
• Implement the process
• Create the user interface
• Integrate the process with services
• Conduct the final playback

After you complete this tutorial, you will be able to do the following tasks:

• Model a process that is based on the process requirements.
• Implement the process, including data variables and services that are required by the process.
• Create the user interface for the process.
• Conduct playbacks at each phase to validate the work that you completed.
• Run and review the process.
