This patch contains the following software changes:


PI05061:

   Problem: When you attempt to remove an IBM Rational ClearCase Unified Change Management (UCM) composite baseline, cleartool.exe may  crash with an application error.

   Fix: Cleartool no longer tries to remove a non-exist baseline from the baseline hash table.


PI12483:

   Problem: When you are working in the IBM Rational ClearCase/Cadence integration, you may find that when you delete a library in the Cadence Library Manager, the library directory is not removed as expected.

   Fix: The fix ensures library directory also gets deleted along with its contents.


PI15885:

   Problem: When using IBM Rational ClearCase 8.0.1.x and there are more than 30 VOBs hosted on a VOB host, for some platforms (such as 32 bit Solaris),  the vob_scrubber will print "too many open file" errors in the vob_scrubber log.

   Fix: With this change, the file descriptor leak in the vob_scrubber has been corrected.


PI18072:

   Problem: When running the IBM Rational ClearCase command "rcleartool lsact" on a Unified Change Management (UCM) stream, you may see a performance issue when there are a large number of activities on the stream.

   Fix: Incorrect initialization code in the sub command that fetch the full activity list for a stream, even when explicit activities were specified, has been removed.


PI44788:

   Problem: When using the IBM Rational ClearCase Remote Client command line interface -- rcleartool -- attempts to use rcleartool mkattr to create or update a string attribute may fail.

   Fix: Fix made to rcleartool to be sensitive to escape characters that must be preserved for subsequent processing.


PI45420:

   Problem: A synchronization problem in IBM Rational ClearCase MVFS may cause inconsistent time-stamp values for view private files.

   Fix: The way MVFS validates and sets time-stamps was improved. Additionally, the resolution of view private files time-stamps will never be better than the resolution of the view storage file-system.


PI46674:

   Problem: IBM ClearCase chtype operations fail with INTERNAL ERROR when ndata versions present.

   Fix: The ClearCase chtype command has been fixed to work correctly when ndata versions are present.


PI48531:

   Problem: When running a UCM deliver using IBM Rational ClearTeam Explorer, automatic merges may not occur and it would appear that a manual merge must happen. A manual merge is not actually required in this case and the deliver will appear to stop.

   Fix: Fixes a problem in the ClearTeam Explorer where UCM Deliver sometimes stops due to inability perform manual merges in a situation where no manual merge should be required.


PI48655:

   Problem: IBM Rational ClearCase CCRC Wan Server process consumes 14mb memory when it is started up, but over time the memory it consumes keeps increasing steadily. 

   Fix: Memory leaks have been fixed.


PI48834:

   Problem: Users of IBM Rational ClearCase may experience a kernel crash or applications may appear to hang when using pt_shell.

   Fix: MVFS was changed to handle file creation options appropriately.


PI50303:

   Problem: If you checkout a file in an IBM Rational ClearTeam Explorer web view before connecting to ClearCase and then try to connect, you will find that ClearTeam Explorer hangs and is unresponsive.

   Fix: Fixes a problem in the ClearTeam Explorer that causes the application to hang when the user navigates to a folder within a view without connecting to the server.
