Tivoli Storage Manager for Databases, Data Protection for MS SQL
The collocate parameter for the storage pool assigned to the Data Protection for
filespace
the MS SQL client node should be set to
to ensure that individual data
stripes stay on separate removable volumes. The default value is no. Not doing
so may require more operations to make the data for each stripe of a restore
simultaneously accessible.
The txngroupmax option in the dsmserv.opt file must be at least one more than
the maximum number of stripes to be used for backup or restore operations
regardless of media. The default value is 40.
Tivoli Storage Manager for Mail, Data Protection for Lotus Domino
To optimize the recover process, use collocation for the file space containing the
transaction log files if they are stored on sequential media on the Tivoli Storage
Manager server. The transaction log files are stored in a separate file space from
the database files on the Tivoli Storage Manager server.
Tivoli Storage Manager for Mail, Data Protection for MS Exchange
The txngroupmax parameter must have a value of 12 or greater.
A singe restore can require a full backup, a differential backup, or multiple
incremental backups. We recommend using collocation if these backups are
stored on removable media. Use a collocation by file space if you plan to restore
multiple storage groups in parallel. This is recommended because all data for
any one storage group is required within one Storage Manager Server file space.
Tivoli Storage Manager for Advanced Copy Services
Increase the value of the commtimeout option in the dsmserv.opt file to 600
seconds to prevent a time-out from occurring during large database backups.
