WDMap: Reindexing an HFSQL data file
Not available with this kind of connection
WDMap can be used to determine whether an HFSQL data file needs to be reindexed, as well as to reindex an HFSQL data file. Two types of reindex operations are available: - Normal reindexing: Classic reindexing (with statistics and without compaction).
- Reindexing with Compaction: Reindexing with compaction (retains only active records. All the crossed or deleted records are permanently deleted).
Reminder: - The indexes are reorganized by the reindex operation. After the indexing operation, the access to indexes is optimized. The indexing operation may be required if the index file is lost or damaged.
- WDMap allows you to easily reindex a data file. However, to reindex a data file more completely, use the WDOptimizer tool.
- A data file can also be reindexed using Windows Explorer. Simply select the "Optimize" option from the context menu of the data file to be re-indexed. Then, the reindexing is performed by WDOptimizer.
WDMap started from the editor To reindex a data file: - Display the data file to reindex (for more details, see Viewing the records found in a data file).
- To perform:
- normal reindexing: select "Tools ... Reindexing . Normal" option.
- a reindexing with compaction Select the "Tools . Reindexing . With compaction".
WDMap started by the "WDMAP.EXE" program To reindex a data file: - In the wizard, select "Reindex a file" and go to the next step.
- Select the data file to be reindexed and confirm.
