Database Administration Utilities
With the Uncompression utility, you can expand a compressed database file created by the Compression utility. The Uncompression utility reads the compressed file and restores the database file to its uncompressed state.
You can access the Uncompression utility in the following ways:
From Sybase Central, using the Uncompress Database wizard.
At the command prompt, using the dbexpand command. This is useful for incorporating into batch or command files.
