To use a compressed dump for an archive database, you must:
Create the compressed dump with the with compression = <compression level> option of the dump database command.
Create a memory pool for accessing the archive database.
Dumps generated with “compress::” cannot
be loaded into an archive database. Therefore, any references to
compression in this chapter refer to dumps generated using the with
compression = <compression level> option.
Compression logic has changed in version 12.5.4. For information about compatibility issues, see “Compatibility issues for a compressed dump”.
