Hi

Columns in ezscript monitor table (ezscheduled_script) is defined as "not null default ''" which is not oracle compatible.
Probably, the "default ''" should be removed as the column should never have empty value

Don't forget to update share/db_schema.dba, kernel/sql/mysql/kernel_schema.sql and kernel/sql/postgresql/kernel_schema.sql when fixing this ( in addition to the sql files in the extension itself )
