Are you considering migrating your data from Rational DOORS to Rational DOORS Next Generation(RDNG)?
Are you looking for guidance and best practice before you begin to be successful first time?
If so, then your starting point is definitely the detailed guidance on developerWorks on how to Migr
New Sizing and Best Practice Guide on Jazz.net's Deployment wiki
Since the developerWorks article was published, we realized that more detailed sizing information was required prior to executing the migration of data packages from DOORS 9 to RDNG. We collated pertinent sizing information from the Rati
There are significant improvements to the import timings with RDNG 6.0.2 release, so please refer to this article if you are evaluating an existing or future migration as this could indeed be an influencing factor.
The document details:
Sizing Guidelines for Rational DOORS Next Generation 6.x
Recommendations on the maximum sizes of your modules, projects and repositories so as to maximize your success when importing your packages and working in the future within RDNG.
The considerations for hardware are simplified from guidance published elsewhere in the Deployment wiki, but here they are explained within the context of how to plan for your new world.
Guidance on how to convert your Rational DOORS modules prior to migration
Invariably there will be modules and projects within DOORS 9 which will not match up to the guidance prescribed for RDNG. Use this section to understand how to easily manipulate your data before migrating.
What if the data to be migrated exceeds the recommendations?
The guidance is clearly aimed for the general use cases and is very much our strongest recommendation.
It is understood that there are very large enterprise requirements management estates out there. It is recommended that you contact IBM if this applies to you.

The Jazz architecture allows for multiple instances of specific application servers, such as the Change and Configuration Management (CCM) application (Rational Team Concert), Quality Management (QM) application (Rational Quality Manager) and Requirements Management (RM) application (DOORS Next Gen). These application servers are registered to a common Jazz Team Server (JTS) to form a CLM Instance. The architecture further allows multiple CLM Instances to be formed. You should be aware of the tradeoffs and architectural considerations when multiple instances are needed in order to scale to support your user population/load.
The following article on jazz.net provides details about application, server and architectural considerations in addition to functional differences that you should review while planning: Planning for multiple Jazz application server instances

In DOORS 9, it is not possible via the user interface to manage the "baseline power" for users.
But it is possible to modify the original behavior of DOORS by editing a DXL file and by creating a "special" group for those users.
When a user attempts to create a baseline from the UI, this code will be executed and only users in the group will be able to create baseline.

A tag is a defined value that you can add to configurations to filter the artifacts.
Use content assist to conveniently tag work items in the Eclipse client or Web UI work item editor.
For a particular Project Area, you can identify a list of tags available in work-item in IBM Rational Team Concert (RTC) and export them.

With the new CLM 6.0.1 and upcoming IBM Rational Collaborative Lifecycle Management (CLM) releases, IBM WAS Liberty has replaced the Apache Tomcat application server. The current documentation will not assist you to configure the WAS Liberty to run as a Windows service.
There is an existing Enhancement Request for the same:
As a workaround, you can use the Apache Commons Daemon as an option.
Steps to create the service using Apache Commons Daemon to run CLM 6.0.1 in IBM WAS Liberty:

After installing CAD Integrator on a CAD users machine and assigning the appropriate security groups and licenses, does the user get an error indicating that they do not have a valid CAD Integrator license? Do not panic! This blog is meant especially for you.
The likely cause of the problem is that a problem occurred during the license assignment process. First, double check that the users profile contains the license. If it is missing there, be sure to add it. Second, go to License Manager and click on the radio button next to IBM TRIRIGA CAD Inte

Have you upgraded your IBM TRIRIGA platform only to find that you cannot see any of the graphics that were visible in your previous platform release. If so, you may want to reprocess your drawings.Please note that reprocessing your drawings can take some time, so you might want to plan this process to run during off peak hours.
To reprocess your drawings, follow these steps.
1 - As an application administrator, login to the IBM TRIRIGA Admin Console.
2 - Click on the radio button next to Database Manager
3 - Click on the link titled "Reprocess published drawings".
Under certain conditions, the reprocessing of your CAD drawings may have encountered issues during the upgrade process. It is important to always review the server log file from the 1st server startup after an upgrade. In the case of your drawings, look for "Reprocessing" in the log file. Most of the entries after that line will contain information about the reprocessing of each individual drawing. If a drawing is processed without issue, you should see a series of 7 informational messages starting with "DXF: Processing Header "to "DXF: EOF" if there is a problem during the reprocessing process, you will likely see either an error or warning message between those two informational messages. If that is the case, you will want to follow the steps outlined above once the upgrade processing has completed on that 1st server.
