Changes for Version 3 Release 7--September 1999

The following changes have been made for this edition:

Creation of portable backup sets for clients
The server can create portable backup sets for clients that are at the latest level of Tivoli Storage Manager. The function consolidates a client's active backup files onto portable media that may be directly readable by the client's system for restore operations.

See the following new commands for details:

DEFINE BACKUPSET
DELETE BACKUPSET
GENERATE BACKUPSET
QUERY BACKUPSET
QUERY BACKUPSETCONTENTS
UPDATE BACKUPSET

Performance enhancements
Performance enhancements include the following:

Automatic tuning of selected server options
Selected server options can be tuned automatically by the server. See Appendix B, Tailoring Server Options for a list of options.

Flat file throughput
Capability for overlapping BSAM I/O can increase throughput for flat files.

Database, recovery log, and all storage pool volumes
TSM can specify a size from 0 to 64MB for VSAM I/O pages to allow a faster throughput of data for operations involving the database, the recovery log, and all storage pool volumes.

Support for InfoSpeed communication protocol
The server now supports IBM InfoSpeed for high speed transfer of backup-archive data between the Tivoli Storage Manager server and the UNIX and Windows NT clients over ESCON and SCSI interfaces. See Appendix B, Tailoring Server Options for details.

Database page shadowing
Database page shadowing mirrors every write to a database page so that the server can recover pages that have been partially written to should an outage occur that affects both mirrored volumes. Combined with the MIRRORREAD and MIRRORWRITE server options for the database and recovery log, you can specify your preferred level of protection, recoverability and performance. See Appendix B, Tailoring Server Options for details.

Database load and audit enhancements
A new utility has been added to recover the contents of the database when the server is offline. See the DSMSERV UNLOADDB command for details.

Database snapshot
You now have the choice a making a database snapshot, which is a full database backup to media that can be taken off-site. The database snapshot does not interrupt any database backup series and cannot have incremental database backups associated with it.

See the changed commands for details:

BACKUP DB
DSMSERV RESTORE DB
QUERY VOLHISTORY
RECONCILE VOLUMES

Proxy Web services
See Quick Start for details.

Password expiration controls
You can reset the password expiration period for all or selected users.

See the following changed commands for details:

REGISTER NODE
REGISTER ADMIN

Licensing changes
Some features that formerly required the purchase of licenses are now part of the base Tivoli Storage Manager product.

See the REGISTER LICENSE command for details.
