Creating table space definition information
A table space definition image (TDI) is created after a full database backup completes successfully. It is stored on the IBM Storage Protect™ server with the database backup image. Only database backups for which a corresponding TDI is available can be used for redirected restore with Backup Object Manager.
About this task
The Backup Object Manager must be used to create a TDI
for an offline database backup image. For example, this command starts
an offline database backup by using two sessions:
backom -c b_db -a database alias -S 2A TDI is not created when you use the DB2® command-line interface to run an offline database backup.
There are two methods
available to create a TDI for an online database backup image:
- One method is to use the Backup Object Manager backup function.
For example, this command starts an online database backup by using
two sessions:
backom -c b_db -a database alias -S 2 -O
- Another method is to use the DB2 command-line
interface to start an online backup with the BACKOM_LOCATION parameter
set in the vendor environment file. When the value of this parameter
specifies the backom executable file, the TDI is
stored on the IBM Storage Protect server
after the backup completes successfully. This statement must be included
in the DB2 vendor environment
file:
BACKOM_LOCATION=fully qualified path and name of the backom executable
The DB2 backup command can then be entered on the DB2 command-line interface:db2 backup db database alias online load shared library open 2 sessions
