Error description

  • APAR content:
    =============
    Headline:
    CCRC compare in a symlinked directory errors with 'The internal
    operation 'get_cleartext' failed.'
    
    APAR description:
    
    In IBM Rational ClearCase Remote Client (CCRC) 7.1.x, performing
    a 'Compare with Predecessor' or 'Compare with Another Version'
    operation results in errors similar to either of the following:
    
    -----
    Failed to invoke compare operation
    null
    -----
    
    -----
    Unable to access the version data for
    'C:\ccweb\user1\ccrcview\vob1\symlinktest\dir1\file1.txt': No
    such file or directory
    The internal operation 'get_cleartext' failed.
    -----
    
    - The issue only occurs in directories which are symlinks.
    
    - It has been seen to only occur when two or more elements
    within the same symlinked directory are checked out (all but the
    last checked out element within the directory will fail).
    
    - It can be seen regardless of whether the symlink target is
    within the same VOB or another (cross-vob symlink).
    
    - It occurs whether the target of the symlink is loaded or not.
    
    - It does not occur if the checkouts are performed first in the
    symlink target location.
    
    
    Steps to reproduce the issue:
    
    1. From IBM Rational ClearCase Explorer, add a new directory
    'symlinktest' to source control.
    
    2. Within 'symlinktest', add a new directory 'dir1' along with
    three new file elements contained within: file1.txt, file2.txt,
    file3.txt.
    
    Example structure: \vob1\symlinktest\dir1\file1.txt (file2.txt,
    file3.txt)
    
    3. Within 'symlinktest', add a new directory 'dir2'.
    
    Example structure: \vob1\symlinktest\dir2
    
    4. Right-click 'dir1' in the right-hand pane of ClearCase
    Explorer and select Symlinks > Create Symlink. Select 'dir2' as
    the target.  This will create a symlink path similar to
    '\vob1\symlinktest\dir2\dir1'.
    
    5. Log into CCRC, creating a view loading this VOB.
    
    6. Navigate to \vob1\symlinktest\dir2\dir1.
    
    7. Checkout files individually in this order: file1.txt,
    file2.txt, file3.txt.
    
    8. Attempt to 'Compare with Predecessor' for file1.txt or
    file2.txt.  The operation will error.  Attempt the same for
    file3.txt and the operation will complete as expected.
    
    
    Workaround:
    
    - Perform the checkouts in the symlink target location.
    
    - Ensure no more than one element is currently checked out in
    the directory.
