Hi all,
I read "What is New in ClearCase 4.0" on Rational ClearCase Web site and
found the following new feature.
Extended VOB Support
The Extended VOB support feature upgrades the VOB database
to 64-bit addressing. This allows users to surpass the 2 GB
limit on string files and the 16 million record limit. The
supported platforms for this feature are Solaris 2.6 and
2.7, HP-UX 11.0, and Windows NT 4.0. Users that have reached
the 2 GB or 16 million record limit and decide to take
advantage of this feature will need to reformat their VOBs.
This is an optional reformat only for this feature and not
required for any other feature in 4.0. On Windows NT systems
if you take advantage of the new extended VOB format you
will also pick up support for storing native Windows NT SIDS
in Windows NT based VOBs. This new feature provides better
support for trusted domains when a ClearCase community of
users spans multiple domains and trust relationships are
changing.
Advantage: Improved scalability to allow greater than 2 GB
string files and 16 million records. Also provides better
support for changes to trusted domains on Windows NT.
What does " 2 GB limit on string files and the 16 million record limit"
mean? Does that mean one VOB in ClearCase 3.2.1 can contains no more than
2GB string files and 16 million records? How can I found usage of one VOB
has occupied and how much limit it reached?
Thanks for your help in advance!
Elynna
