New features and other changes in Rational ClearCase version 9.0.2.x

Question & Answer


Question

What are the new features and other changes in ClearCase®?

Answer

Descriptions of the changes are organized by version-specific tabs.

V9.0.2.4

OS native installer for MVFS, Linux only

As of this release, on Linux only, the multiversion file system (MVFS) is installed through the OS native installer when using IBM Installation Manager. Note that the Configuration panel in the Installation Manager related to the MVFS module is no longer displayed. In the unlikely case that the installation of the MVFS fails, a warning displays at the end of the installation. The installation of the rest of ClearCase completes normally.

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

Now, the composite and recommended baselines from the public and private VOBs cannot be removed by default when using the rmbl command. When the rmbl command is executed with the [ –public ] argument, only the composite and recommended baselines from the public VOB cannot be removed.

ClearTeam Explorer (CTE)

  • IBM Rational ClearCase ClearTeam Explorer now supports derived objects.
  • For IBM Rational ClearTeam Explorer, the ClearCase Search feature is enabled for Dynamic views. On the ClearCase Search dialog box, use the Checked out resources option to do a search for the checked-out files at the View level only. For more information, see also technote http://www.ibm.com/support/pages/node/6457899.

Installation

  • While installing the ClearCase product package using the Installation Manager GUI, you can now select the versions of Microsoft Visual Studio that you want to integrate with ClearCase. This feature is only enabled when Microsoft Visual Studio is already installed on your computer. For supported versions of Microsoft Visual Studio, see the Software Product Compatibility Report (SPCR) Tool http://www.ibm.com/software/reports/compatibility/clarity/index.html.
  • The name of the Automatic View Client feature is changed to Automatic Views in the ClearCase product package.

ClearCase CCRC WAN servers on Apache Tomcat

You can now use the Tomcat server to host an automatic view WAN server. For more information, see technote http://www.ibm.com/support/pages/node/872402.

V9.0.2.3

Cadence Virtuoso integration enhancements

The Check-out function and the Check-in function now support multiline comments.

Changes to commands

By default, the checkvob command skips an element that is already locked and indicates the element was skipped. Now, the checkvob command can analyze the locked element for a problem if invoked with the -process_locked argument. Additionally, the checkvob [-process_loc/ked] command indicates for any issue found in the locked element, though the issue cannot be fixed.

ClearTeam Explorer (CTE)

While logging in to CTE using the SmartCard option, now you can use a customized friendly name instead of the default name CTESmartCardCert for the authentication. To use the customized friendly name, create the file .cte_cert_label (for ClearCase®) or .cmi_cert_label for (for ClearQuest®) under the HOME directory on the client side. Additionally, the file must contain the same friendly name as provided in the SmartCard certificate.

V9.0.2.2

Audited Build Executor

For parallel or distributed builds, clearmake is updated to address a specific scenario related to a build host override with the NOTPARALLEL targets. This change helps to prevent an Audited Build Executor (ABE) reassignment that could result in a stuck build. This update is applicable to override builds, or builds where makefiles or environment variables contain the CCASE_BLD_HOST variable, and the build server host list changes for different targets.

Cadence Virtuoso integration enhancements

  • The WorkArea Manager (WAM) can now recover items with a version as "checkedout but removed" in a dynamic view. As part of this change, Recover checkedout but removed files is now available on the ClearCase menu.
  • In the ClearCase-Cadence integration, if a user cancels a checkout of a version and provides the -keep option, then the _keep file is created irrespective of any change made to the checked-out file. The _keep backup file is created only if the element is changed and the CCASE_CDS_CANCEL_WITH_KEEP environment variable is set.

Changes to commands

The setcs command now provides an option to update the configuration specification (also referred to as the config spec) separately if invoked with the -nupdate argument without updating the snapshot view. To update the snapshot view, you can use cleartool update. The setcs -nupdate command helps to update the config spec successfully irrespective of existing or non-existing load rules.

Installation

ClearCase® 9.0.2.2 now supports Installation Manager 1.9.x.

New platform support

  • Windows 10 CU 2004
  • Red Hat Enterprise Linux (RHEL) 8.2
  • Red Hat Enterprise Linux (RHEL) 7.8

V9.0.2.1

Audited Build Executors

For parallel or distributed builds, the Audited Build Executor (ABE) session tracking limits the number of ABEs to be equal to the -J value or the number of build server hosts, whichever is smaller. This update is applicable to override builds, or builds where makefiles or environment variables contain the CCASE_BLD_HOST variable and the build server host list changes for different targets.

ClearTeam Explorer (CTE)

When you use the Add to Source Control option in ClearTeam Explorer (CTE) and select the Include descendant artifacts of the selected directories option, then the Checkout artifacts after adding to source control option is disabled. This update helps to avoid the automatic deletion of files from a folder when you select the Undo Checkout option.

Changes to commands

Clearmake builds now execute correctly with the -v option during the normal Clearmake executions. Previously, clearmake builds executed with the -v option used to cause an inadvertent error message even though the build continued successfully (Error: Unable to invoke operation "compare" for manager "text_file_delta": No child processes).

New platform support

  • Windows 10 version 1909 (November 2019 Update)
  • Red Hat Enterprise Linux 8.1

V9.0.2

Installation

  • Launchpad is no longer available. If you want to use IBM® Installation Manager to install ClearCase® and you do not already have it, you must manually download and install Installation Manager. To get Installation Manager, see technote http://www.ibm.com/support/pages/node/609575.
  • The Roll Back function in IBM® Installation Manager is not supported between major ClearCase® product versions such as 9.0.2 and 9.0.1.x. For more information, see technote http://www.ibm.com/support/pages/node/130797.

Security

Crypt::SSLeay v0.72 is removed from the product due to incompatibility with OpenSSL 1.1.1d.

If you use ratlperl, ccperl, cqperl, SSL/TLS connections, LWP::UserAgent, and Crypt::SSLeay in your own perl scripts, you are affected by this change.

The suggested fix is to stop importing the Crypt::SSLeay SSL implementation module in your perl scripts and letting LWP::Protocol::https default (or explicitly use) to the provided IO::Socket::SSL module.

About upgraded Net::SSLeay to version 1.88, for change history and usage, see http://metacpan.org/release/CHRISN/Net-SSLeay-1.88.

About upgraded IO::Socket::SSL to version 2.066, for change history and usage, see http://metacpan.org/release/SULLR/IO-Socket-SSL-2.066.

If you use ratlperl, ccperl, cqperl, and use either Net::SSLeay or IO::Socket::SSL, then you are affected by these changes. See the corresponding module documentation for interface changes.

ClearCase on AWS

ClearCase® can run successfully on the Amazon Web Services (AWS) Cloud. AWS provides virtual machines and other services that can be used to run ClearCase® servers and clients. For more information, see the article Using ClearCase in AWS.

Status of the feature level
