The directory context for Sybase SQL scripts is found in the install-dir\DirXMLUtilities\jdbc\sql\sybase_ase\install directory on Windows or install-dir/lib/dirxml/rules/jdbc/sql/sybase_ase/install directory on UNIX/Linux platforms.
From a Sybase client, such as isql, log in as the sa user and execute the 1_install.sql installation script.
For example, from the command line, execute:
isql -U sa -P -i 1_install.sql
By default, the sa account has no password.
