job_type
This attribute specifies the type of job that you are creating. If it is not specified, an error is generated. The supported values are:

'PLSQL_BLOCK'
This specifies that the job is an anonymous PL/SQL block. Job or program arguments are not supported when the job or program type is PLSQL_BLOCK. In this case, the number of arguments must be 0.

'STORED_PROCEDURE'
This specifies that the job is a PL/SQL or Java stored procedure, or an external C subprogram. Only procedures, not functions with return values, are supported.

'EXECUTABLE'
This specifies that the job is a job external to the database. External jobs are anything that can be executed from the operating system's command line. Anydata arguments are not supported with a job or program type of EXECUTABLE. The job owner must have the CREATE EXTERNAL JOB system privilege before the job can be enabled or run.

'CHAIN'
This specifies that the job is a chain. Arguments are not supported for a chain, so number_of_arguments must be 0.
