When creating a new database, large file processing is enabled if the .st file specifies a fixed-length extent size or a maximum size for a variable-length extent that is greater than 2 GB. Large file processing requires an Enterprise database license and is enabled by default. Large file processing is not available for sub-Enterprise license and is disabled by default. The following example shows the .st file of a database with large file processing enabled:

# Sample Structure Description File: largedb.st
#
# largedb.st to create database largedb with large file processing enabled.
#
# A fixed length bi file of 1GB and a variable length bi file with a maximum # size of 4GB.
