Large file support for databases created, copied, or opened using this and later releases of OpenEdge will differ based on license level. This change will affect databases created or copied using the following commands and utilities:
  • PROSTRCT CREATE
  • PROCOPY
  • PRODB
  • CONV1112
  • PROREST

For systems running with Enterprise license, large file support will be enabled by default.

Opening a database on systems running with Enterprise license will enable large file support if it is not already enabled. The following message will be written to the database .lg file upon enabling large file support: 
Database with large file support disabled is being opened under
Enterprise license. Large file support will be enabled. (19400)

Large file support is not available for systems running with sub-Enterprise license (Workgroup and Personal) and is disabled by default.

Opening a database on systems running with sub-Enterprise license will disable large file support if it is enabled. The following message will be written to the database .lg file upon disabling large file support:
Database with large file support enabled is being opened under
sub-Enterprise license. Large file support will be disabled. 
(19399)
In the event existing file extents exceed 2GB when opening a database running with sub-Enterprise license, the database will fail to open and the following message will appear on screen and in the .lg file:
Database having existing file extents greater than the 2GB large 
file size limit cannot be opened under a sub-Enterprise license. 
(19401)

Large file support may be enabled or disabled depending on the license when the database is opened in a non-read only mode.

Note: Although large file support is enabled in an OpenEdge database, it is still limited by the operating system support.
