Scaling the Collaborative Lifecycle Management (CLM) solution across an enterprise

Scaling the Collaborative Lifecycle Management (CLM) solution across an enterprise, is the title of the webinar Tim and I presented recently. Tim and I have worked on this content for a while and consider it important. Please also see  Tim’s related post Getting to a right-sized Jazz environment. There is additional reading below.

Objectives of the presentation

Scaling the v6.0.x Collaborative Lifecycle Management (CLM) solution across an enterprise often includes multiple instances of a given Jazz application. What multi-Jazz application options are available and what are the considerations?

  • What topologies and general multi-Jazz application options are available
  • How Jazz applications such as Change Configuration Management (CCM), Quality Management (QM) and Requirements Management (RM) relate to a Jazz Team Server (JTS)
  • The impact, advantages and disadvantages of multiple CLM Applications
  • What to consider when scaling and developing usage models adopting one of these deployment options to avoid surprises

If you are interested in this presentation, you can find the replay of the webinar here in the Rational Team Concert Enlightenment Series.

The slides are shared here.

Can’t connect to RTC running with Jazz Authentication Server

Are the Eclipse client and RTC 6.0.x Plain Java Client Library based automation and tools no longer working since RTC was set up with the Jazz authentication Server? This could be due to an issue with the shipped codecs.

There is apparently an issue with Java API clients in environments where CLM, especially the RTC Server is set up with the Jazz Authentication server. The Eclipse client and Plain Java Client Library based automation can not connect to RTC any more. See the related RTC RFE 371953.

The reason seems to be due to the codecs shipped with the Eclipse client and the plain Java Client libraries. Please see the post RTC Plain Java API and Jazz Authentication Server.


The issue seems to be:

  1.  Jazz Authentication Server requires at least version 1.4 of the Apache commons-codec library.
  2. The RTC Java client includes version 1.3.  Replacing 1.3 with 1.4 or higher resolves the issue.

General Solution

In the Eclipse client and the Plain Java Client Libraries folders, find and replace the file org.apache.commons.codec_1.3.0.v20100518-1140.jar with a 1.4 or later.  Version 1.10 is the latest  you can get it from all prior versions are here:  Then update your classpath to point to the new .jar.

How to implement this, differs for the several options like Eclipse Client for a user, Eclipse Client for SDK and Plain Java development and so forth. If you create extensions and automation, my suggestion is to develop against a Jetty based test server and a real development Apache or WAS Liberty Profile based system without the  Jazz Authentication Server. If you want to use the automation against a life server, you can follow the description below to get your final automation up and running.

I will try to find the time to describe more details for the Eclipse client itself, but would suggest to get in contact with IBM support in the mean time.

Solution for Plain Java Client Libraries

I was able to test this today and got it working for a Plain Java Client Libraries application that was running stand alone outside of the Eclipse client. So far I tested RTC 6.0.2.

This did not work for me with RTC6.0 against an RTC 6.0.3 M6.

I downloaded the file from and extracted the content. In the extracted file I located the commons-codec-1.10.jar file.

I created a folder ApacheCommons in the same folder that contains my Plain Java Client Libraries JAR file and placed a copy of the commons-codec-1.10.jar there.

The application is in a file application.jar. I use a batch file to start it. I just added the folder ApacheCommons to the class path as first entry. This way the first commons codec that is found is the newest one. When running the batch file the plain java client libraries application ran as expected.

The batch file looks as follows.

set JAVA_HOME=..\TeamConcert\jazz\client\eclipse\jdk
set PLAIN_JAVA=../PlainJavaAPI
set COMMONS=../ApacheCommons
set USERID="deb"
set PASSWORD="deb"

%JAVA_HOME%\jre\bin\java -Djava.ext.dirs=%COMMONS%;%PLAIN_JAVA%;%JAVA_HOME%/jre/lib/ext -cp %COMMONS%;%PLAIN_JAVA% -jar automation.jar %REPOSITORY% %USERID% %PASSWORD% "deb"

Another approach is

  1. Find the codecs plugin from a 6.0.3 client e.g. named org.apache.commons.codec_1.6.0.v201305230611.jar.
  2. Replace the codecs plugin shipped with the plain java libs with the one from the first step.


I hope this helps some people out there. I will try to add more details if I can find the time.

Upgrading your CLM system? – Definitive checklist.

Upgrading the IBM CLM solution is sometimes received as complex and users struggle with it. Yesterday I was notified that there was a blog from a colleague providing a check list that helps making this easier and more likely successful. I thought this is worth reblogging to make it easier to find.

Please find the information in Paul’s blog post Upgrading your CLM system? – Definitive must-read checklist just published. The link points to our Deployment Wiki which is always worth looking at for all things related to deployment, install, setup and configuration.

How to filter RTC email notifications by project or by user

Spamming the in-boxes of your project with notification mails? This is a reblog of Marks internal blog.

The RTC Mail Filtering Problem

A common requirement for Rational Team Concert administrators is the need for limiting email notifications for a single RTC project or user.  There are many scenarios which might drive this need.  Here are some examples:

  • Thousands of work items are imported and you want to not cause notifications for the new work items.
  • A new field is added and data from the old field is copied over, affecting many work items.  We don’t want users to be notified.
  • A subset of users now use a different RTC server, and they no longer want notifications from the old project, but they need to remain active in the old project.

Unfortunately, the current RTC product as of version 6.0.1 does not support this requirement.  Notifications are controlled at the Jazz Team Server level.  The JTS may control multiple RTC, Rational Quality Manager, and Rational Doors Next Generation repositories.  Turning off notifications in the JTS turns off mail for all RTC, RQM, and RDNG projects from all repositories controlled by that JTS server.  Mail  generated for all of those RTC, RQM, and RDNG projects while notifications are off in the JTS are lost.
This leaves administrators with a tough choice:  lose all mail for everything connected to the JTS, or live with excessive and unwanted notifications for a single project.

A Solution:  Milters

We have found and implemented a solution for this requirement, milters.  Milters are plugins for Sendmail that add additional functionality to Sendmail.  The “milter-regex” milter plugin permits filtering mail using regular expressions.

These are the overall steps for utilizing the regex milter:

  • Set up a machine with Sendmail and install the milter-regex plugin
  • Configure Sendmail to allow mail from the JTS server machine in /etc/mail/access
  • Develop a set of regular expressions which cause mail from a particular project or user to be found and filtered out and update the /etc/mail/milter-regex.conf configuration file
  • Restart the milter-regex service
  • Edit the email settings of the JTS to point to your Sendmail machine as the mail SMTP Server

You can easily add and remove projects and users from the filtering list by editing the /etc/mail/milter-regex.conf file.  You can turn off filtering completely by restoring the JTS SMTP Server value back to its original setting.

Regular Expressions

You’ll have to examine your email templates to determine the project and user information for the various email formats.  Here’s an example of the configuration statements for our email templates to filter out all mail for project “Project XYZ”:

reject “Mail filtered for project: Project XYZ”
body ,Team Area:.* Project XYZ,i
body ,Project Area:.* Project XYZ,i

Both “body” statements are required.  The “reject” statement defines a message which is logged into the /var/log/messages log file when a piece of mail is filtered out.

This is an example of filtering for a single user:

reject “Mail filtered for user: Mark E. Ingebretson”
body ,The user ‘Mark E. Ingebretson’ made a .* request,i*
body ,Mark E. Ingebretson mentioned you in,i
body ,Mark E. Ingebretson.*changed on,i

If you are a user of our IBM Systems servers and need email filtering, you can submit an ITHELP request.

Other Approaches

There is another approach from Sam provided on the forum here: Manage User E-mail Preferences for Mass Updates. It has been sitting on my Interesting Links page for a while. Time to show it here.

A new solution s available for RTC 6.0 starting with iFix03 if you are using the Java API. Use the Skip Mail Save Parameter.



I found the topic very interesting and related questions also come up on, so I decided to re-blog and promote this when Mark showed this to me. I hope it helps our users all over the world. I hope that this solution can help other RTC administrators address this important requirement.

JavaScript Attribute Customization – Where is the log file?

A lot of users try Java Script based attribute customization and often run into issues. They ask on the forum to get the issue solved. Unfortunately the questions usually lack the information required to help. This post explains how to retrieve log information to be able to provide this information.

Where are the Script Log files?

Java Script attribute customization can use the console to log text messages into a log file.

console.log("My message");

The question is, where are the log files?

The script context

Java Script attribute customization scripts are, as far as I can tell, run in one of the following contexts:

  1. The Eclipse Client
  2. The Web Browser
  3. The RTC Server

Dependent on the context it is run, the log information can be found in a log file that is created and maintained by the

  1. The Eclipse Client
  2. The RTC Server

Please note that the logging information is not in the RTC Application log file CCM.log.

The Wiki entry about attribute customization provides hints about how to log data and how to log data and how to debug scripts in the section Debugging Scripts. Similar information is provided in the Process Enactment Workshop for the Rational solution for Collaborative Lifecycle Management.

Unfortunately both only talk about how to find the server log information for Tomcat. Since Websphere Application Server and WAS Liberty are also valid options, how can one find the log files in this case?

Find The Eclipse Workspace Log

As background, note that the Eclipse Client as well as the RTC Server are based on Eclipse technology. This common technology is used to log the data and determines the log file location and name.

Each running Eclipse has a workspace location and stores meta data and log information in this workspace. The workspace is basically a folder in the file system. The metadata is stored in a sub folder with the name .metadata. The log file is in this folder and named .log.

For the RTC Eclipse client and for scripts that run in this context, open the Eclipse workspace folder that is used and find the .log file in the .metadata folder.

For the RTC Server, the easiest way to find this workspace and the enclosed log file that I have been able to find is to search for the folder .metadata. For Tomcat and WAS Liberty standard installs go to the folder where the RTC Server was installed and then into the sub folder server. From here search for the folder .metadata.

For Websphere Application Server (WAS) go the profile folder for the profile that includes the RTC server deploy and search there.

Here an example search for a test install based on WAS Liberty:


Note that every Jazz application has its own Eclipse workspace with metadata folder and workspace log file. The one interesting for RTC attribute customization is the workspace of the RTC server. The folder structure includes the context root of the Jazz application. Each application has a different context root which typically matches the application war files name prefix. The RTC application typically has the context root and application war files name prefix ccm. Open the workspace for this application and find the log file.

Looking Into the Log File

You can look into the log file. Please make sure to use a tool that does not block writing to the log file, while you are browsing its content. The log file is kept open by the server when it is running and blocking it from writing is not what is desired. Use more or an editor that reads the file and does not block it. For windows users: notepad does lock the file for writing. Use a different tool such as notepad++.

The Process Enactment Workshop for the Rational solution for Collaborative Lifecycle Management provides some examples for how logs look like and can be created. If you can’t find the log entry you are looking for, always check the server log as well. Maybe the script runs in a different context than you expect.

Here an example for log entries:


Load Errors

It might happen, that an expected log entry is not found in any of the log files. In this case make sure to check for script loading errors as well as thrown exceptions at the time the script was supposed to run.

Load errors can be caused by different reasons.

One reason can be that attachment scripts are not enabled. There are enough indicators in the Attribute customization editor in Eclipse that a user should have spotted this these days.

Another reason can be that the script is syntactically not correct and can not be interpreted as a valid JavaScript. One reason for a script not being recognizable as a valid script that I have seen recently is an incorrect encoding. If an external editor is used to edit the script and the script is then loaded from the file, make sure that the script has a correct UTF-8 encoding. If in doubt change the encoding to UTF-8 and reload the script.

Why would the encoding be important? The encoding controls the format of the content. it is hard to determine the encoding from a file and it is often not checked. But expecting a specific encoding but loading a file that was encoded in a different one can cause to find unexpected content. This can can cause the JavaScript not being recognized as JavaScript and the load fails.

Debugging vs. Logging

Using the debugging techniques explained in the Wiki entry in the section Debugging Scripts and in the Process Enactment Workshop for the Rational solution for Collaborative Lifecycle Management should be the preferred option and is usually more effective.

Looking at the logs is still a valid option, especially to be able to log execution times and to find script loading issues and for scripts that are run in the background in the server context, such as conditions.

I found using the Chrome Browser and the built in Developer Tools to be most effective. The scripts can easily be found in the sources tab under the node (no domain). Make sure to enable the debug mode as explained here: Debugging Scripts.



This post explains how to find the log files that contain log information written by JavaScript attribute customization scripts. I hope that this helps users out there and makes their work a little bit easier.
