Synopsis

endview [ –ser/ver ] view-tag

Description

Deactivates the specified view. The view tag must be registered in the same region as that of the host at which this command is issued. If the view tag is registered in another region, this command reports that the view tag cannot be found. Do not deactivate a view for the purpose of backing it up.

The exact behavior of this command varies according to the kind of view.

Dynamic view

The endview command deactivates the dynamic view. It removes all references to the view from the MVFS on the current host. The view tag is no longer displayed in the MVFS directory (on Windows this directory is, by default, M:\). The –server option terminates the view's view_server process. Without –server, endview does not affect the view's availability from computers other than the current one. For information about view_server, see the IBM Rational ClearCase Administrator's Guide.

If a Windows drive was assigned to the view, the drive is marked unavailable in the drive table (see the Windows net use command) and can be reused.

In a mixed UNIX, Linux, and Windows environment, any NFS drive that was mounted to support access to the view storage directory is unmounted (assuming no other active views or VOBs require it).

Important: Processes set to or associated with a view are stranded if you deactivate that view without exiting the processes, which can cause MVFS activities to fail. To recover from this situation, use startview or setview to restart the view on all computers that were using it, or kill the processes manually with the UNIX and Linux kill command or the Windows Task Manager.

To avoid this situation, follow these guidelines:

  • Before you run endview (without –server) on your computer, exit all processes on your computer that are set to or associated with the view, including any processes started by other users. Any processes that are running when you deactivate the view will be stranded.
  • Before you run endview –server, exit all processes set to or associated with the view, including processes on other computers, processes, or both that are started by other users.

Snapshot view

When issued with the -server option, endview ends the view's view_server process on the host where the view-storage directory resides. Any ClearCase command issued from the view-storage directory restarts the snapshot view's view_server process.

endview used without the -server option has no effect on a snapshot view.

Restrictions

With the –server option, you must have permission to modify the view.

Options and arguments

Stopping the view server

Default
endview does not stop the view's view_server process; the view remains accessible from other network hosts.
–ser/ver
Terminates the view's view_server process.

Specifying the view to deactivate

Default
None. You must supply a view tag.
view-tag
Deactivates view view-tag if view-tag specifies a dynamic view. If view-tag specifies a snapshot view, -server must also be specified to deactivate the view.

Examples

The UNIX system and Linux examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.

The Windows examples that include wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the UNIX system and Linux shells or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.

  • Deactivate the dynamic view r3_main on the local host. Do not terminate the view_server process.

    cmd-context endview r3_main

  • Same as previous example, but terminate the view_server process, making the view temporarily unavailable to all hosts.

    cmd-context endview –server r3_main

  • On a Windows system, stop and restart the dynamic view alh_main, which is currently assigned to drive W.

    cmd-context endview alh_main
    cmd-context startview alh_main
    net use
    ...
    Unavailable W:    \\view\alh_main       ClearCase Dynamic Views
    ...    net use w: \\view\alh_main
    Command completed successfully.

  • Deactivate the snapshot view r4_main.

    cmd-context endview –server r4_main
