"cleartool space" reports on the space usage of the vob itself, on the file
system itself.
This is not what should be of interest to you. Use "string_report.sun5" as
David mentioned,
to look INSIDE the strings file and see if there is any space left for
further expansion.
I had to call the US support office to obtain this file (they will have to
email it to you, as
it does not come as part of the standard package).

Hi Alex,
Thanks for your information. The tool I was told by Rational support is
"cleartool space". But it seems not the report I want to see. I got another
sample report from another user in CCIUG that is what I prefer to see. He
doesn't mention any tool to generate that report. I will keep you posted if
I get any infomation about that .
Regards,
Elynna

ClearCase uses a database to track all of the ClearCase meta-data i.e.
every
time you create a new element, checkin a version, label a version etc. an
event
record and/or an element record is created in the database.
So, if you have a very long lived database with a large number of files, it
is possible
to reach the maximum number of records that the database can reference, at
which point
no further operations will be possible, as they will no longer be recorded.
The strings file is used to store just that - strings. These strings can be
the result of
derived object creation etc., so certain operations will add to this
string,
unfortunately this
string file never shrink. Even by removing a large number of elements etc
plus event history
the file may then contain "hollow regions" however the size of the file
itself will not shrink,
as such it is difficult to know when the limit is going to be exceeded.
Rational provide a utility, which you will have to ask Tech Support for,
which will produce
a report of the strings file informing you of its spare capacity.
Hope this helps.
Alex.

Subject: [cciug] 2GB limit
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
