Full-text search indexes must be rebuilt when you upgrade to 6.0.6.1 or later
First occurrence
6.0.6.1
Problem
In the 6.0.6.1 release, the Apache Lucene full-text search engine was upgraded to a more recent version. This upgrade requires all existing full-text search indexes that were created in 6.0.6 or earlier to be rebuilt. Full-text search indexes must be rebuilt for both the ELM servers and the Engineering Workflow Management Client for Eclipse IDE.
Workaround
Typically, when you upgrade an installation by using the upgrade scripts, the full-text search indexes from the earlier installation are copied to the new installation. However, the upgrade scripts in 6.0.6.1 and later do not copy previous indexes from version 6.0.6 or earlier (including interim fixes). Instead, the new server automatically rebuilds the indexes in the background after you start it. Results of full-text searches might be incomplete until the reindexing operation is finished; the progress of the reindex is periodically written to the server log file.
Alternatively, instead of allowing the server to rebuild full-text search indexes online, you can rebuild them manually by running the repotools-<app> -rebuildTextIndices command after the upgrade is complete, but before you start the server, where <app> is one of am, ccm, or qm. Note that reindexing might be a lengthy process and can take many hours for a large database. In the web client, a system alert in the banner states that reindexing is in progress.
If you follow a manual upgrade procedure instead of running the upgrade scripts, you must ensure that the full-text indexes are not copied from the old installation to the new installation. If the new installation is configured to use the same full-text index location as the old installation (the value of the com.ibm.team.fulltext.indexLocation property in the old and new teamserver.properties file is the same absolute path name), you must either run the repotools-<app> -rebuildTextIndices command before you start the server, or delete the contents of the folder at that location before you start the server. You might want to preserve the old contents if you decide to abandon the upgrade and roll back to the previous release.
If an application is clustered, the offline reindexing procedure (using repotools) or the online procedure (ensuring that the full-text index folder is empty before starting the server) must be performed on each node in the cluster.
The Engineering Workflow Management Client for Eclipse maintains a local full-text search index for the Team Artifact History view. When you upgrade the Engineering Workflow Management Client for Eclipse to version 6.0.6.1 or later, the full-text search index is automatically deleted, which means the artifact history is cleared and will accumulate artifacts again after the upgrade.
For ELM servers, complete one of these steps:
For online background indexing, no action is required except to ensure that the full-text index folder is empty before you start the server
For offline indexing before you start the server, run the appropriate repotools-<app> -rebuildTextIndices command.
The Rhapsody Model Manager server and client require a locale setting for non-English support
First occurrence
6.0.6
Problem
Rhapsody elements for non-English labels display incorrectly in the Rhapsody Model Manager web interface, unless the correct locale is set on the client machine.
Workaround
Manually set the locale on the client machine.

The Associate Change Request action in 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 Rhapsody client, you must already have defined a Change and Configuration Management (CCM) repository connection in the Engineering Workflow Management 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 Engineering Workflow Management Eclipse client to the server that manages the work items:
1. Open the Engineering Workflow Management 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.
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.
- Log in to Jazz Team Server, go to jts/admin > Server > License Key Management and note all the licenses on the server.
- In IBM Rational License Key Center, under License Management, click Return Keys.
- Click the product link that you want to return the license keys for, and then click Return.
- After the license is returned, click Get Keys.
- Click the product link to generate licenses for.
- When prompted, provide the required information and click Generate.
- Download the file that contains the new licenses.
- Log in to Jazz Team Server, go to Server > License Key Management and reimport the new license files.
- To add a license, click Add, accept the license agreement if you agree to its terms, and then complete the steps in the wizard.
- Log in to Jazz Team Server, go to jts/admin > Server > License Key Management and note all the licenses on the server.
- In IBM Rational License Key Center, go to View keys by host or View keys by user.
- Enter the information about the host or the user.
- Select the product to generate the license for.

The file path for the Rhapsody client on Windows is limited to 256 characters
First occurrence
6.0.5
Problem
It’s not possible to open and save a Rhapsody model to a path that is longer than 256 characters.
Workaround
It’s recommended to use a short path to the EWM sandbox folder to avoid reaching 256 characters.

You cannot associate a change request when you delete an OSLC link from DOORS Next or DOORS
First occurrence
6.0.5
Problem
When you create an OSLC link from DOORS Next or 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 DOORS Next or 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:
Navigate from DOORS Next to Rhapsody Model Manager by clicking the OSLC link that you want to delete.
In Rhapsody Model Manager, delete the existing OSLC link, and then you can select a change request to associate with the change set.
