    Which of the following are valid program types for a lightweight job? (Choose all that apply.)
    A. PLSQL_BLOCK
    B. EXECUTABLE
    C. JAVA_STORED_PROCEDURE
    D. STORED_PROCEDURE
    E. EXTERNAL

      PLSQL_BLOCK and STORED_PROCEDURE are the only valid program types that can be used with a lightweight job.
    Programs
    A program object (program) describes what is to be run by the Scheduler. A program
    includes:
    An action: For example, the name of a stored procedure, the name of an executable found
    in the operating system file system (an "external executable"), or the text of a PL/SQL
    anonymous block.
    A type: STORED_PROCEDURE, PLSQL_BLOCK, or EXTERNAL, where EXTERNAL indicates an
    external executable.
    Number of arguments: The number of arguments that the stored procedure or external
    executable accepts.
    A program is a separate entity from a job. A job runs at a certain time or because a certain
    event occurred, and invokes a certain program. You can create jobs that point to existing
    program objects, which means that different jobs can use the same program and run the
    program at different times and with different settings. With the right privileges, different
    users can use the same program without having to redefine it. Therefore, you can create
    program libraries, where users can select from a list of existing programs.
    If a stored procedure or external executable referenced by the program accepts
    arguments, you define these arguments in a separate step after creating the program. You
    can optionally define a default value for each argument.
