Dbspace and logical-log tape backup devices

You can specify different tape devices for the primary and secondary database servers.

If you use ON-Bar, set the ON-Bar configuration parameters to the same value on both database servers. For information about the ON-Bar parameters, see the HCL OneDB™ Backup and Restore Guide.

The following ONCONFIG parameters must have the same value on each database server:

LTAPEBLK
LTAPESIZE
TAPEBLK
TAPESIZE

To use a tape to its full physical capacity, set LTAPESIZE and TAPESIZE to 0.
