SAP ASE version 16.0 introduces changes to some existing utilities.
When you install SAP ASE into a directory with a specific user, other users may not be able to use it because they lack write permission for the installed $SYBASE directory.
SAP ASE 16.0 lets you specify another user for both configuring new servers during or after installation, thereby allowing multiple users to use the same installed SAP ASE directory.
To support this new feature, SAP ASE 16.0 uses the -D data_directory option for these utilities to specify a directory other than the default.
