Figure 51. Whole consistent backup, commandfile backup_offline_beach
To guarantee that a database’s datafiles are consistent, shut down the
database with the NORMAL, IMMEDIATE or TRANSACTIONAL options
before making a whole database backup. To bring up the database in the
desired state., we chose the sequence:
shutdown immediate;
startup force dba;
shutdown immediate;
startup mount;
Note: Unlike TDP for Oracle for UNIX, we do not need to specify as many
channel definitions. The only one that is required is DSMO_AVG_SIZE, the
rest are left as defaults.
Channel definitions:
DSMO_AVG_SIZE is a size estimate used by the TSM server to reserve
space on TSM storage
The allocation of multiple channels is only possible when TSM node’s
MAXNUMMP (maximum mount points allowed) is greater than or equal to
the number of channels.
