About ClearCase automatic views

Question & Answer


Question

What should I know before using ClearCase® automatic views?

Answer

V8.0.1.7

Notes on using automatic views

CM API: folder read omits removed files

In an automatic view, a local read (readProperties()) of the Folder.CHILD_MAP or Folder.CHILD_LIST properties omits files is removed; for instructions on accessing the omitted files, see http://www.ibm.com/support/pages/node/524953.

Limitations

Automatic views do not support all of ClearCase® functionality. For a list of limitations, see http://www.ibm.com/support/pages/node/526891.

Known issues

Automatic views are affected by the following problems:

V8.0.1.8

New support

Automatic views now support the following features:

  • Unix and Linux servers, with the limitations that Solaris x86 and multicomponent VOB tags are not supported
  • Integrations with ClearQuest®, Rational Team Concert, Visual Studio, and Rational Desktop products
  • ClearCase® MultiSite
  • The rcleartool remote command line interface

Support for rcleartool

This release introduces new rcleartool commands and changes to several existing commands to support automatic views. Some limitations apply.

New commands

rcleartool hijack pname ...

Hijacks file elements. This command is supported in an automatic view only.

  • pname specifies the file that is to be hijacked; you cannot specify a directory or a symbolic link.

rcleartool unhijack [-keep] pname ...

Unhijacks hijacked file elements. This command is supported in an automatic view only.

  • -keep creates a view-private copy of the file named element-name.keep.
  • pname specifies the file that is to be unhijacked.

Changed commands

  • The edcs command has separate synopses for web and automatic views:
    • Web view: edcs [ –ove/rwrite | –ren/ame ] [ –pti/me ] [ file ]
    • Automatic view: edcs [ –ove/rwrite | –ren/ame ] [ file ]
  • The mkview command for automatic views includes a new -ptime option:
    • mkview –automatic –tag automatic-view-tag ] [ –tco/mment tag-comment ] [ –tmo/de { insert_cr | transparent | strip_cr } ] [ -ptime ] [ –str/eam stream-selector ] [ –clt/xt_storage cltxt-cache-storage-pname ] automatic-view-storage-pname
  • The setcs command has separate synopses for web and automatic views:
    • Web view: setcs [ –force ] [ –ove/rwrite | –ren/ame ] [ -ptime ] pname
    • Automatic view: setcs [ –force ] [ –ove/rwrite | –ren/ame ] pname
  • The update command has separate synopses for web and automatic views:
    • Web view–update elements: update [ –print ] [ –ove/rwrite | –nov/erwrite | –ren/ame ] [ –ptime ] [ pname ... ]
    • Web view–load elements: update –add/_loadrules [ –print ] [ –ove/rwrite | –nov/erwrite | –ren/ame ] [ –ptime ] pname [ ... ]
    • Automatic view–update elements: update [ –print ] [ –ove/rwrite | –nov/erwrite | –ren/ame ] [ pname ... ]
    • Automatic view–load elements: update –add/_loadrules [ –print ] [ –ove/rwrite | –nov/erwrite | –ren/ame ] pname [ ...]

Support for disconnected mode

The use of rcleartool in disconnected mode is not fully supported.

Unsupported commands

The following rcleartool commands are not supported in an automatic view (they are supported in a web view):

  • chactivity
  • checkin -atomic
  • deliver
  • diff
  • get
  • merge
  • mkbl
  • mkbranch
  • rebase

About VOB symbolic links

Some limitations affect VOB symbolic links in the context of an automatic view:

  • You cannot supply a path that includes a symbolic link as an argument to an rcleartool command such as checkout.
  • Similarly, the objects selected by rcleartool find might not include VOB symbolic links.

However, the interactive traversal of symbolic links is supported; for example, you can use the rcleartool cd command to navigate paths that include symbolic links.

Note: You cannot create symbolic links in ClearTeam Explorer, regardless of the view type.

Limitations

Automatic views do not support the following features:

  • Atomic checkin
  • Version-extended pathnames from non-ClearCase tools
  • Client-side shared-cleartext cache scrubbing
  • Unix or Linux client support
  • Proxy server support
  • Authenticating firewall support

Modifying a ClearCase installation to add automatic view support

Some configuration is required after you modify an 8.0.1.8 installation to add automatic view support; for instructions, see http://www.ibm.com/support/pages/node/530295.

Known issues

  • The clearmake build utility.

Changes to CM API

A new property and a new method that support automatic views are introduced in this release:

  • The CcDirectory.AGGREGATED_VIEW_PRIVATE_LIST property allows callers to retrieve a list of view-private files that does not include hijacks or checkouts.
  • The CcView.updateServerUrl() method allows users to continue to use their views after a server rename operation.
