New features and other changes in Rational ClearCase version 9.1.0.x

V9.1.0.5

Decorate eclipsing resources in dynamic/automatic views

On the preferences page of Rational® ClearTeam Explorer (CTE) for Eclipse, the Decorate eclipsing resources in dynamic/automatic views option is renamed to Decorate eclipsing resources in dynamic/automatic views (requires restart). If you want to decorate or not decorate eclipsing resources in the ClearTeam Details view, you should enable or disable this option and restart CTE.

Eclipse upgrade

The Eclipse runtime used by ClearTeam Explorer is updated from version 4.6 to 4.23.

Installation

• For the IBM® Rational ClearCase 9.1.0.5 installation on Linux and Windows, you must have a 64-bit Java Runtime Environment (JRE) specifically for Java 11 installed before you install ClearCase. A Java 11 JRE can be obtained from Adoptium at https://adoptium.net. For more information, see IBM Documentation.

  Note: Java 11 is not required for the Core ClearCase (UNIX) and the Server only (linux_ppc64le and linux_s390x) platforms, which do not include any Java-based software with ClearCase. Java 8 is no longer supported.

• When installing or updating or uninstalling ClearCase on a Windows platform, the installation process is improved to avoid a reboot of your system if the MVFS is successfully loaded or unloaded. If you are installing ClearCase on a system for the first time or reinstalling after a successful uninstall, then a reboot is not required. Some situations might still require a reboot, which is normal. However, if you are uninstalling ClearCase, or updating to a newer version, ensure that there are no open references to MVFS resources to avoid the reboot. The ClearCase Control Panel now displays a list of processes that have reference to MVFS resources when you press the Stop ClearCase button on the Services tab. By closing the processes with references to MVFS resources, you can avoid the need for a reboot. For more information, see technote https://www.ibm.com/support/pages/node/7028842.
• The rcleartool command-line interface is now automatically configured by the installation process. The setup process that was previously required when running rcleartool for the first time is now not required.
• On Linux_x86_64, when you update an earlier version of ClearCase to ClearCase 9.1.0.5 or later, then the Update Not Supported panel is displayed with the message An update is not supported and the only way to do the update is to uninstall the current version and install the new version. For more information, see technote https://www.ibm.com/support/pages/node/7015375.

IBM Rational ClearCase Admin Console GUI

On the IBM® Rational ClearCase Admin Console GUI on Windows, when you click View Name in the All Views section or VOB Name in the All VOBs section, the respective Properties dialog opens as expected.

Support for ClearTeam Explorer

The ClearTeam Explorer is only available on Windows (win_x86_64) and Linux (linux_x86_64) platforms.

Cadence Virtuoso integration enhancements

When you set the CCASE_CDS_SIMPLIFIED_MSG environmental variable to TRUE, now Cancel check-out messages will also be logged into the Command Interpreter Window in a simplified form along with the existing check-in and check-out messages.

Changes to commands

The lsbl command, when executed with the -stime_desc option, can print the baseline list in reverse or descending order based on the timeline.

New platform support

Microsoft Visual Studio integration enhancements

• After integrating IBM® Rational ClearCase 9.1.0.4 with Microsoft Visual Studio, projects added in ClearCase® now show glyphs and context menus when you open a project in Microsoft Visual Studio 2019 and later versions. Additionally, now you can check out the project. For more information, see technote https://www.ibm.com/support/pages/node/6619671.
• After integrating ClearCase® 9.1.0.4 with Microsoft Visual Studio 2022, you can now create a new project from the Microsoft Visual Studio 2022 UI. You can still create a new project from Microsoft Visual Studio 2019 after clearing the cache or resetting the user data.

The abe_starter link is referenced as the default method for a clearmake process to start an audited build executor (abe) on a remote UNIX/Linux machine. Remote abe executions are only used when there is a -J value specified with clearmake and a build host file or list is also specified with the list of remote build servers.
• ClearCase® 9.1.0.3 and later now support RHEL 9. The prerequisite packages for RHEL 9 are different from RHEL 8. For more information about the prerequisite packages, see technote https://www.ibm.com/support/pages/node/6600045.

For more information, see https://www.ibm.com/support/pages/node/205891.

Integration of ClearCase and Microsoft Visual Studio

After the integration of ClearCase® 9.1.x with Visual Studio 2019 and Visual Studio 2017, when you navigate to Visual Studio 2019/2017 > Tools > Options, it now correctly displays the source control bindings as Rational ClearCase.

Cadence Virtuoso integration enhancements

• Added new environment variable CCASE_CDS_SIMPLIFIED_MSG. If the environment variable is set to TRUE, the check-in and check-out messages will be logged into the Command Interpreter Window (CIW) in a simplified form.
• Now, a warning message is displayed in the Cannot CheckIn/Cannot Cancel Checkout dialog box when you accidentally do a check-in or do a check-out of an edited view in the Library Manager. This helps to avoid an override of the changes.
• While checking in files from the Library Manager or Work Area Manager (WAM) or cellview editors, now you have the option to do the check-in and label simultaneously. To do this, select the Apply Label Post Checkin checkbox on the Check In dialog box and enter the appropriate values in the Label Operations and the Label Options fields.

Changes to Commands
