This patch contains the following software changes:


PI28582:

   Problem: In a ClearCase nonpreserving replica with ACLs enabled, syncreplica replay of a mkelem oplog may generate a second "create file element" event in the database, which can cause failures in reformatvob and mkreplica -import.

   Fix: The duplicate "create" event will no longer be generated.


PI30193:

   Problem: When performing audited builds in a ClearCase dynamic view the customer will see an "ACCESS DENIED" error log entry when deleting a derived object, although the delete operation completes successfully.

   Fix: When a MVFS file is about to be deleted, MVFS tries to flush any pending change on the cache to its cleartext file, however derived object files are stored on a VOB, which are opened as read-only. Trying to flush files opened as read-only causes the "ACCESS DENIED" error seen on the log. Now MVFS only request a flush on such situation if the cleartext file is stored on a VIEW, and not on a VOB.


PI41700:

   Problem: ClearCase chtype may fail in windows client / server configuration due to missing cleartext; the cleartext is generated but there is a delay of ~ 5 seconds before the client sees the cleartext file (due to Windows SMB2 caching).

   Fix: The chtype command has been fixed to fail without committing any changes when a version's cleartext is unavailable.  
These Windows  registry keys can be set to '0'  (all DWORD) to disable the portion of Windows SMB2 caching causing the problem.
 
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation \Parameters 
DirectoryCacheLifetime=0 
FileNotFoundCacheLifetime=0 
FileInfoCacheLifetime=0


PI61697:

   Problem: When building in an ClearCase dynamic view, you may experience a hang.

   Fix: The lock acquisition rule has been fixed to resolve this specific case.


PI64788:

   Problem: After writing to a file and closing it, if an application sets its attributes, ClearCase MVFS will change the attributes back to the values the file had when it was closed.

   Fix: Before setting attributes after having a file changed and closed, MVFS now checks if the attributes has been set by an application and will persist it if so.


PI68851:

   Problem: When using the ClearCase Remote Client command line interface -- rcleartool -- attempts to use rcleartool mkattr to create or update a string attribute may fail with 'invalid string "{passed string}"'.

   Fix: Non-interactive invocations of rcleartool mkattr for string attributes no longer strips the embedded quotes and should apply the attribute properly.


PI69005:

   Problem: The ClearCase binary_delta  type manager may not remove temporary file(s) after a failed type manager operation.

   Fix: The ClearCase binary_delta  type manager was fixed to remove temporary files.


PI70236:

   Problem: When a building in a ClearCase dynamic view, you may experience sporadic random read/write errors

   Fix: This issue with IBM Rational ClearCase MVFS has been resolved.


PI73356:

   Problem: ClearCase "chmaster -stream" may not change mastership of timeline objects.

   Fix: On schema 80 and feature level 8, "chmaster -stream" will change mastership of timeline objects whether it has timeline folder or not.


PI73587:

   Problem: When working in ClearTeam Explorer (CTE) , you may find that the file you just checked out does not appear to be checked out only when the path is accessed through address bar.

   Fix: Check out status is displayed as expected in ClearTeam Details pane, even when the file is accessed from the address bar.
