This patch contains the following software changes:


MVFS:

   Problem: IBM Rational ClearCase users might encounter STOP errors when accessing files using dynamic views on Microsoft Windows(R) platforms

   Fix: The ClearCase MVFS filesystem has been modified to provide significant enhancements to reliability when running Dynamic Views on Windows and improvements in ClearCase compatibility with antivirus software on Windows platforms.


PI05748:

   Problem: The IBM Rational ClearCase mvfsstat utility can report an incorrect value for maximum RPC delay time on multi-processor systems.

   Fix: IBM Rational ClearCase has been modified to report the maximum RPC delay time correctly.


PI07723:

   Problem: IBM Rational ClearCase users might encounter STOP errors when using Cygwin version 1.7.25 or 1.7.26 inside a dynamic view.

   Fix: IBM Rational ClearCase has been modified to eliminate the STOP errors when using Cygwin in a dynamic view.


PI09398:

   Problem: A system on which a parallel audited build is running in IBM Rational ClearCase may hang due to a locking deadlock in the file system.

   Fix: The order of locking file system resources when writing audit records during a parallel audited build was modified to avoid a potential deadlock.


PI09606:

   Problem: During Rational ClearCase builds customers may experience a system crash due to a race condition.

   Fix: IBM Rational ClearCase MVFS has been modified to avoid this system crash.


PI09946:

   Problem: Rational ClearCase Clearmake may cause BSOD.

   Fix: Memory management was corrected and resolves this issue.


PI11080:

   Problem: During Rational ClearCase builds customers may experience a system crash due to a race condition.

   Fix: IBM Rational ClearCase MVFS has been modified to avoid this system crash.


PI11919:

   Problem: During Rational ClearCase builds customers may experience a system crash due to a race condition.

   Fix: IBM Rational ClearCase MVFS has been modified to avoid this system crash.


PK67686:

   Problem: Applications running in a ClearCase dynamic view context cannot make TCP calls on systems running Microsoft Windows(R) Vista or later operating systems.

   Fix: Applications running in a ClearCase dynamic view can now make TCP calls correctly.


PM13349:

   Problem: Executing a program out of an IBM Rational ClearCase Versioned Object Base (VOB) can cause a system panic on a Microsoft Windows(R) system if certain anti-virus programs are enabled.

   Fix: IBM Rational ClearCase has been modified to work properly in the presence of anti-virus software.


PM18005:

   Problem: IBM Rational ClearCase builds on Microsoft Windows(R) XP systems will not always list executable programs created as derived objects in the audit files for subsequent steps in the build.

   Fix: IBM Rational ClearCase will now list executable files created as derived objects in audit files.


PM18831:

   Problem: When you execute a program that is stored as a view private file in a dynamic view in IBM Rational ClearCase on Microsoft Windows(R) 7 the task manager may list the name of the program as the name of the cleartext file in the view storage directory and not the name of the executable.

   Fix: IBM Rational ClearCase will now cause the task manager to display the name of an executable file properly.


PM35859:

   Problem: A system panic could occur on Microsoft Windows(R) 7 systems running java under IBM Rational Clearcase.

   Fix: The Multi Version File System (MVFS) of IBM Rational ClearCase has been modified to prevent these system panics.


PM68899:

   Problem: IBM Rational ClearCase users might sometimes encounter STOP errors when making large builds using dynamic views on Microsoft Windows(R) platforms

   Fix: IBM Rational ClearCase  has been modified to prevent STOP errors while doing large builds.


PM75360:

   Problem: The Perl stat() function performs slowly when accessing files in remote dynamic views under IBM Rational ClearCase.

   Fix: IBM Rational ClearCase has been modified so that the stat() function in perl will perform better.


PM76839:

   Problem: Setting the Registry Key MvfsViewAttachMup can cause IBM Rational ClearCase users to receive permission denied errors when using robocopy.

   Fix: IBM Rational ClearCase has been modified so that the MvfsViewAttachMup is no longer needed and robocopy now works correctly.


PM84238:

   Problem: A Micorosoft Windows(R) system running IBM Rational ClearCase and Symantec Endpoint Protection can encounter a system panic when moving a file from a local disk into a dynamic view.

   Fix: IBM Rational ClearCase has been modifies so that Symantic Endpoint Protection will no longer cause a system panic moving files into a dynamic view.


PM87962:

   Problem: If Microsoft Security Client is installed on an IBM Rational ClearCase client system, running an executable which was winked in during the build process can cause a Windows STOP error.

   Fix: The ClearCase Multi Version File System (MVFS) has been modified to be compatible with Microsoft Security Client.


PM88679:

   Problem: When Symantec 12.1.2.x is installed on a Microsoft(R) Windows system running the IBM Rational ClearCase client, applications which write to a temporary file in a scratch directory could trigger a Windows STOP error when that temporary file is renamed as a view-private file.

   Fix: The MVFS filesystem has been updated to be compatible with the filter drivers in Symantec 12.1.x.


PM90121:

   Problem: IBM Rational Clearcase on Microsoft Windows 7 may encounter a system hang when performing parallel builds within a dynamic view

   Fix: The IBM Rational Clearcase Multi-Version File System code has been modified to alleviate hangs during parallel builds.


PM90880:

   Problem: When stopping IBM Rational ClearCase services on an HP-UX system which had been running a substantial load, it was possible to receive errors unmounting some VOBs, and that in turn prevented successful unmount of the viewroot.

   Fix: Changes were made in the ClearCase Multi Version File System (MVFS) file inactivation code to correctly release all resources on the last close of a file which had been opened by multiple processes.


PM99147:

   Problem: IBM Rational ClearCase users would enounter occasional system panics during large builds  on Microsoft Windows(R) systems

   Fix: IBM Rational ClearCase has been modified to prevent system panics during large builds on Microsoft Windows(R) systems.
