Workarounds and Limitations: Known issues in Rhapsody Model Manager 6.0.6

Rational Rhapsody 8.3.1 and Rhapsody Design Manager are not updated from the server if you installed the feature to import Design Manager projects to Rhapsody Model Manager

First occurrence
6.0.6

Problem
If you install Rhapsody Model Manager, including the feature to import projects from Rhapsody Design Manager, and you open a Design Manager model in Rhapsody, the expected message that notifies you of updates to Rhapsody and the Design Manager client is not displayed.

Workaround
In the rhapsody.ini file, change the EnableDmToRmmMigration value to FALSE, and open the Design Manager model again. After the updates are applied, change the value of EnableDmToRmmMigration back to TRUE.

Rhapsody Model Manager displays unresolved OSLC links to remote artifacts

First occurrence
6.0.6

Problem
If you open a Rhapsody Model element in the Rhapsody Model Manager property editor, you might see unresolved OSLC links to remote artifacts. This problem can happen when you navigate from another application to open a model, for example, from requirements in Rational DOORS Next Generation, or when you use a direct link to the model element without specifying the OSLC configuration context as a URI query parameter. Because Rhapsody Model Manager doesn’t have the OSLC configuration context, it can’t retrieve the details of remote artifacts.

Workaround
On the toolbar, click the Current Configuration menu and select a configuration to work in. This action reloads the page in the correct configuration context.

The Associate Change Request action in Rational Rhapsody requires a repository connection

First occurrence
6.0.6

Problem
If you want to associate a change request with a Rhapsody Model Manager change set that is in the Rational Rhapsody client, you must already have defined a Change and Configuration Management (CCM) repository connection in the Rational Team Concert Eclipse client. Otherwise, you get the following error:

Error while associating work item to change-set containing files
L:\Demo Sandbox\Model\Model_rpy;Pkg.sbsx
Failed to associate work-item https://server:9443/ccm/resource/itemName/com.ibm.team.workitem.WorkItem/10 to change-set:
Repository connection was not found for work item identified by the following URL:
https://server:9443/ccm/resource/itemName/com.ibm.team.workitem.WorkItem/10

Workaround
You need to create a new repository connection from the Rational Team Concert Eclipse client to the server that manages the work items:

1. Open the Rational Team Concert Eclipse client.
2. Create a new Jazz Repository Connection.
3. Specify the URI path to https://<server>:<port>/ccm/

Licensing errors might occur if you upgrade the Java environment or upgrade applications to 6.0.5

First occurrence
6.0.5

Problem
If you upgrade your version of Java to a fix pack that was built after April 2017, or you upgrade an application to version 6.0.5 or later and are using WebSphere Liberty, licensing errors might occur. The errors occur because earlier licenses were signed with the MD5 algorithm, which is now blocked by newer versions of Java.

For example, the License Key Management page for Jazz Team Server might display the following error in the Description field: CRJAZ1236I A development time license is being used. Similarly, the jts.log file might display the following error: CRJAZ0965I The file was not a valid server or client access license activation key.

The latest license files no longer contain the MD5 algorithm because IBM and Oracle Java introduced restrictions on JAR files that are signed with weak algorithms and keys.

Workaround
The licenses in the IBM Rational License Key Center were updated to use a different signature algorithm.

After you upgrade your server to version 6.0.5 or later, obtain the updated licenses from the IBM Rational License Key Center to replace your current licenses. If you previously used floating, token, or authorized user single install licenses, install their updated versions. Your existing user license assignments are kept during the installation of the updated licenses.

Important: If you are not upgrading all applications at the same time, you must apply an interim fix to the applications at earlier versions before you upgrade Jazz Team Server. The following interim fixes contain the compatible version of Java:

• 6.0.4 interim fix 007 and later
• 6.0.3 interim fix 010 and later
• 6.0.2 interim fix 015 and later
• No version of 5.0.2 contains a compatible Java version. For 5.0.2, complete the steps in the IBM Support flash article.

If you cannot apply the interim fix before the upgrade, upgrade Jazz Team Server and then complete the steps in the IBM Support flash article. If you do not apply the interim fix or complete the steps in the article, the internal licenses do not load on Jazz Team Server and the applications might experience issues.

To update your current license files, follow the instructions in the Interactive Upgrade Guide or complete the following steps based on the type of license:

For term (floating or authorized user) or token licenses:

Note: For token licenses, you are only required to download the jazztokens.zip file. You do not have to download the license.dat file because it does not contain changes.

1. Log in to Jazz Team Server, go to jts/admin > Server > License Key Management and note all the licenses on the server.
2. In IBM Rational License Key Center, under License Management, click Return Keys.
3. Click the product link that you want to return the license keys for, and then click Return.
4. After the license is returned, click Get Keys.
5. Click the product link to generate licenses for.
6. When prompted, provide the required information and click Generate.
7. Download the  file that contains the new licenses.
8. Log in to Jazz Team Server, go to Server > License Key Management and reimport the new license files.
9. To add a license, click Add, accept the license agreement if you agree to its terms, and then complete the steps in the wizard.

For non-term floating and authorized user licenses:

1. Log in to Jazz Team Server, go to jts/admin > Server > License Key Management and note all the licenses on the server.
2. In IBM Rational License Key Center, go to View keys by host or View keys by user.
3. Enter the information about the host or the user.
4. Select the product to generate the license for.
5. Click View Licenses for Selected Product Lines.
6. Select the license and click View Details.
7. Click Download Keys.
8. Log in to Jazz Team Server, go to Server > License Key Management and reimport the new license files.
9. To add a license, click Add, accept the license agreement if you agree to its terms, and then complete the steps in the wizard.

Note: If you imported trial licenses before the newer versions of Java were adopted, you might still receive errors in the jts.log file even after you import the updated licenses. For example, you might receive this error: CRJAZ0965I The file was not a valid server or client access license activation key. You can ignore these errors.

Rhapsody Model Manager cannot be registered on a CLM server upgraded to 6.0.5 on WebSphere Application Server Liberty

First occurrence
6.0.5

Problem
After you upgrade to 6.0.5, you must register Rhapsody Model Manager because it’s a new application that did not exist before 6.0.5. However, when you try to register, you get the following error:

The server could not access the discovery URL for the application. If you have configured a virtual host for an application, the virtual hostname must be used in the URL for the application. ID CRJAZ2081E

The working copy of the WebSphere Application Server Liberty configuration application.xml file, which is located in the <Installation Folder>/server/liberty/servers/clm/conf folder, does not contain an entry representing the Architecture Management (AM) application. You get this error because this configuration file was copied from the older version of the server, which is not aware of the new Rhapsody Model Manager application.

Workaround
After the upgrade to 6.0.5 and before registering the Rhapsody Model Manager application, follow these steps:

1. Stop the server.

2. Open the <Installation Folder>/server/liberty/servers/clm/conf/application.xml file in a text editor.

3. Add the following content before the “<!–  Applications that delegate authentication to a JTS –>” comment:

<application type=”war” id=”am” name=”am” location=”${server.config.dir}/apps/am.war”>
       <application-bnd>
           <security-role name=”JazzAdmins”>
               <group name=”JazzAdmins” />
           </security-role>
           <security-role name=”JazzProjectAdmins”>
               <group name=”JazzProjectAdmins” />
           </security-role>
           <security-role name=”JazzUsers”>
               <group name=”JazzUsers” />
           </security-role>
           <security-role name=”JazzGuests”>
               <group name=”JazzGuests” />
           </security-role>
       </application-bnd>
   </application>

4. Optional: If, during the installation, the default root context of the RMM application was changed, make the corresponding changes to the <application …> tag entry:

    a) ID field

    b) Name field

    c) Name of the WAR file

5. Save the changes.

6. Start the server.

7. Register and configure the Rhapsody Model Manager application in the usual way.

You cannot associate a change request when you delete an OSLC link from Rational DOORS Next Generation or Rational DOORS

First occurrence
6.0.5

Problem
When you create an OSLC link from Rational DOORS Next Generation or Rational DOORS to Rhapsody Model Manager, you can associate a change request to track corresponding modifications.

However, when you try to delete an existing OSLC link from Rational DOORS Next Generation or Rational DOORS, you don’t have this ability, because these applications do not provide a dialog box where you can select a change request.

If the Require Work Items and Comments precondition is selected on the server side for a given project area, deleting the link fails with an error message.

Workaround
This workaround is available starting in 6.0.5 interim fix 001:

1. Navigate from Rational DOORS Next Generation to Rhapsody Model Manager by clicking the OSLC link that you want to delete.
2. In Rhapsody Model Manager, delete the existing OSLC link, and then you can select a change request to associate with the change set.
