IC86558: TIVOLI STORAGE MANAGER SERVER NEEDS TO MUCH TIME TO RESPOND ON QUERIES FROM DATA PROTECTION FOR EXCHANGE.

IBM Tivoli Storage Manager (TSM) server V6.3.3.x interim fix downloads

APAR status

• Closed as program error.

Error description

• Tivoli Storage Manager server has to scan all grouped backup
  objects from application files and to verify that each Meta-data
  object has the corresponding Data-data object available, per
  current design.
  Since Exchange server 2010 Microsoft changed the default size of
  the log files to 1 MB due to performance reason in a DAG
  environment, there might be a huge number of objects (several
  thousands) grouped together.
  Depending on the number of mailbox databases and the number of
  backup versions, kept from each mailbox database, the response
  on a query for all backup objects, issued by Tivoli Storage
  Manager for Mail, Data Protection for Exchange may take a very
  long time, even if just the few FULL backups will be listed.
  
  Data Protection Versions Affected:
  Tivoli Storage Manager Server on all supported platforms and at
  all current supported versions.
  
  Initial Impact:
  Medium
  
  Additional Keywords:
  TSM TDP zz61 zz62 zz63
  

Local fix

• Limit the number of objects that has to be queried by:
  1) Query for active backups from all mailbox databases only.
  2) Query for all backup objects - active and inactive - from one
  mailbox database only.
  
  Increasing the size of the log files might also be an option on
  a single Exchange server installation, but this is not
  recommended in a DAG environment
