Rational ClearCase Commands Reference

Mounting All VOBs

The mount –all command mounts all public VOBs listed for your host's network region in the VOB registry. (It does not mount private VOBs or VOBs whose tag entries include the mount option noauto.) On UNIX systems, this command executes at ClearCase startup time; see the init_ccase reference page.

UNIX—Mounting of Public and Private VOBs

A public VOB can be activated by any user; if the mount-over directory does not already exist, it is created.

A private VOB can be activated only by its owner. The root user or VOB owner can use the standard mount(1M) command to mount a private VOB; other users cannot mount it. The mount-over directory must already exist and be owned by the VOB owner.

Windows—Mounting of Public and Private VOBs

A public VOB can be activated with the following command:

Usually, the system administrator automates this command for ClearCase users at login time.

Any user can mount any VOB, public or private. The private designation means only that a VOB must be mounted separately, by name.

VOB Tags and the VOB Storage Registry

You reference a VOB by its VOB tag (the full pathname of its mount point), not by its storage area pathname. The mount command uses the VOB tag to retrieve all necessary information from the ClearCase registry: pathname of VOB storage area, pathname of mount point, and mount options.

Making a Mount Persistent

Specifying Mount Options

Note: The time-out values specified in several of these mount options affect the view's metadata latency (the delay before changes to VOB metadata become visible in a dynamic view other than the one in which the changes were made). Longer time-out values improve performance at the expense of greater latency. Shorter time out values decrease latency, but also have an impact on view performance because the caches must be refreshed more frequently.
