  • VersionVault:
    res/erve [ –c/omment comment | –cfi/le comment-file-pname
    | –cq/uery| –cqe/ach | –nc/omment ] [ –cact ] pname ...
  • VersionVault Remote Client:

The reserve command changes the checkout status of a checked-out version of an element from unreserved to reserved. A temporary reserve checkout of version event record is written to the VOB database.


ACL authorization

If ACLs are enabled, the principal must have the following permissions:
  • read-info on VOB object
  • mod-checkout on the element

Non-ACL authorization

You must have one of the following identities:

  • Element owner
  • Element group member
  • VOB owner
  • root (UNIX® and Linux®)
  • Member of the VersionVault administrators group (VersionVault on Windows®)


An error occurs if one or more of these objects are locked: VOB, element type, element, branch type, branch.


(Replicated VOBs only) Your current replica must master the branch.


There must be no reserved checkouts of the branch.

Options and arguments

Event records and comments

Creates one or more event records, with commenting controlled by your .versionvault_profile file (default: –nc). See the comments reference page. Comments can be edited with chevent.
–c/omment comment | –cfi/le comment-file-pname |–cq/uery | –cqe/ach | –nc/omment
Overrides the default with the option you specify. See the comments reference page.

Specifying the elements

Reserves each checked-out version in the change set of the current activity in your view.
pname ...
One or more pathnames, each of which specifies an element. The checkout in the current view is changed, unless you use a view-extended pathname to specify another view.


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.
