New features and other changes in Rational ClearCase version 9.0.1.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.

V9.0.1.4

Cadence Virtuoso integration enhancements

There are now uniform dialogs for operations such as checkin, checkout, and cancel checkout across all graphical user interfaces.

Metadata and other files in libs and cells are now visible to the designers so that they can perform data management operations on them.

In the Hierarchy Manager, on selecting Show Hierarchy in Tree View , cellviews in the Hierarchy tab will be displayed in a tree representation and data management operations can also be performed in Tree Representation.

The Rational ClearCase Cadence Virtuoso integration is now available as a separate extension offering and can be independently installed using IBM Installation Manager. For instructions on how to install this integration, see technote http://www.ibm.com/support/docview.wss?&uid=ibm10718519.

Changes to commands

The rcleartool command now supports the mkcomp , lscomp , and rmcomp subcommands.
Note: For the rcleartool command, rmcomp works only when used with a server running ClearCase 9.0.1.4 or later.

For the mkcmprovider subcommand, the disableRTCBridge key can now also go on the VOB config (in the connection section). The same key at the stream level will override the VOB key. Also, it can go in a -data file as connection.disableRTCBridge .

Depending on your operating system, these are the updated trust store file paths. You can compare the updated templates to your versions in the corresponding pathnames without the .template suffix.

  • UNIX: /var/adm/rational/clearcase/config/cacert.pem.template
  • Windows: C:\Program Files (x86)\IBM\RationalSDLC\ClearCase\config\ccrc\ccrc_ucmcq_key.*.template

ClearTeam Explorer (CTE) enhancements

With UCM you can now refresh the activity list on a stream during any common dialog box operations (for example, Check Out, Check In, Add to Source Control, Rename, Move, and so on). If any activity is added or deleted after a common dialog box is opened, in the drop-down list for the Select Activity section, select <Refresh…> to refresh the activity list.

Cadence Virtuoso integration enhancements

  • Apply and Remove Label operations have been consolidated into a single Label dialog box. You can either choose to apply or remove labels from the selected items. In addition, you can filter cellviews and select from a choice of label options such as locking and unlocking a label type. Both apply and remove operations now present a consolidated label report as well.
  • Fetching the label types now lists them in a sorted order in the Label dialog box.
  • The ClearCase Work Area Manager (WAM) now shows the attached labels on design elements in a newly introduced Label column. Also for the selected element, labels, if any, are listed in the Label list box on the Work Area Manager window.
  • For ClearCase Delete, in addition to the originally selected elements, you can now add more elements such as other libraries, cells, and cellviews; and then all the selected elements can be deleted at the same time.
  • Use the ClearCase Config Spec Editor to set your configuration specification for your workspace. This editor lets designers configure their workspace in terms of libraries, cells, cellviews, and design hierarchies based on provided version selectors.

New platform support

  • WebSphere Application Server / IBM HTTP Server 8.5.5.12
  • Ubuntu 16.04.2 4.8-HWE on the following platforms:
    • Linux 32-bit (linux_x86) and 64-bit (linux_x86_64)
    • Linux Power PC 64-bit Little Endian (ppc64le)

      Recommendation: For the support on ppc64le, during the installation phase, select the Yes, rebuild MVFS using the current kernel source directory option in the IBM Installation Manager.
  • In 9.0.1.1, linux_x86_64 and linux_ppc64le platforms now use a VOB database on-disk format that is compatible with linux_x86. If you used the 9.0.1 release for VOB storage on either platform, before you upgrade to 9.0.1.1, see compatibility details and instructions for reformatting in technote http://www.ibm.com/support/docview.wss?uid=swg22004783.

Microsoft Visual Studio support

This release introduces support for Visual Studio 2017 and discontinues support for Visual Studio 2012.

V9.0.1

ClearTeam Explorer (CTE) enhancements

You can now merge into a hijacked file using the ClearCase Version Tree view. While merging into a view-selected version, you can merge into the hijacked copy and keep up-to-date with changes without converting the hijacked file to a checkout.

Cadence Virtuoso integration enhancements

  • Improved performance in operations involving scanning of checked-out elements in ClearCase Work Area Manager (WAM).
  • You can now specify comments during a rename operation.
  • By default, ClearCase Hierarchy Manager (HM) now displays the design hierarchy in a tree view. Tree view representation ensures better performance for large hierarchies. (This view default is set on the Specification tab. If you clear the Show Hierarchy In Tree View check box, the design hierarchy displays in a flat view.)
  • The .oalib, data.dm and cdsinfo.tag files in unmanaged libraries are now automatically added to source control from the ClearCase Work Area Manager (WAM) and Hierarchy Manager (HM) if the designs (cellviews) in these libraries are being added to source control.
  • For the Cancel Checkout operation, when attempted with the 'keep' option on, cellviews now maintain a view-private copy of the cellview directory.

New platform support

  • Linux 64-bit (linux_x86_64) on the following distributions. For information about the required system packages for ClearCase version 9.0.1 linux_x86_64, refer to technote http://www.ibm.com/support/docview.wss?uid=swg22003747.

For information about changes to automatic views in this release, refer to technote http://www.ibm.com/support/docview.wss?uid=swg21699087.

Changes to commands and APIs

  • The clearmake command now provides insight into where its elapsed time is consumed if invoked with the -d argument. This is particularly helpful for parallel distributed builds, where the time spent waiting for build hosts, or for more parallelism (audited build executor processes or abes), is presented.
  • To improve performance, in the cleartool command facility, for the lsview subcommand, the output of the -prop argument now prints out IP addresses (instead of hostnames). Additionally, the performance of this command is improved by reducing the time spent waiting for responses from off-line view hosts.
  • In the rcleartool command facility, the merge subcommand now supports the -insert and -delete arguments.
  • The CM API CcVersion interface has a new doIsAncestorOf method, which checks the ancestor relationship between two versions.
