The Ferret utility, ferret, lets you display and set storage space utilization attributes of the Teradata Database. Ferret dynamically reconfigures the data in the Teradata file system while maintaining data integrity during changes. Ferret works on various data levels as necessary: vproc, table, subtable, WAL log, disk, and cylinder.
The Ferret utility allows display and modification of the WAL Log and its index.
Ferret includes the following:
- The SCANDISK option includes checking the WAL Log by default.
- The SCOPE option can be set to just the WAL Log.
- The SHOWBLOCKS and SHOWSPACE options display log statistics and space.
