To use a compressed dump for an archive database, you must create the compressed dump
using the with compression = <compression level> option of the
dump database or dump tran command, and create a
memory pool for accessing the archive database.
Note:
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
Creating a Compression Memory Pool
When SAP ASE reads a page from a compressed dump, it selects a compressed block from the dump, decompresses it, and extracts the required page.
