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 IBM® Informix® Backup and Restore Guide.

If you use ontape, the tape size and tape block size for the storage-space and logical-log backup devices must be identical. 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.
