IBM Tivoli Storage Manager V6.3 Fix Pack 5 (6.3.5.000) Server Downloads

APAR status

• Closed as program error.

Error description

• The Tivoli Storage Manager BACKUP NODE/NAS command with TOC=YES
  will pin the active log (recovery log) while generating the
  table-of-contents information into a temporary table.
  
  After completion of the NDMP backup process, either with
  success or failure (i.e. an admin issues CANCEL PROC against
  the backup), the server can leave a pinning transaction open
  to this TOC temporary table for the duration of the server
  TOCLOADRETENTION parameter.  By default, the TOCLOADRETENTION
  parameter is 120 minutes.  The minimum value is 30 minutes.
  
  This behavior can lead to unexpected active log growth.
  
  Customer/L2 Diagnostics:
  Collect log pin diagnostics to determine if an active
  transaction exists against the NDMP.Nodes temporary table,
  but no corresponding thread exists for the transaction.
  
  Initial Impact:
  Medium
  
  Tivoli Storage Manager Versions Affected:
  All V6 Tivoli Storage Manager server users
  
  Additional Keywords:
  TSM ACTIVE LOG PIN PINNED PINNING NDMP CONTENTS TOC PROC
  NDMP.IMAGE.CONTENTS NDMP.NODES TEMP TEMPORARY TABLE CANCEL
  

Local fix

• Run BACKUP NODE without the TOC=yes parameter.  If TOC=yes
  is required, reduce the TOCLOADRETENTION parameter to 30
  minutes to lessen the impact.
