Introduction 

The JobSchedulerPLSQLJob JITL job provides a standardized and parameterized interface for executing Oracle PL/SQLs statements.  The JobScheduler offers out of the box capability to execute PL/SQLs, passing parameters to the PL/SQL or collecting and passing on the results of a PL/SQL execution to next job step as a JobScheduler Order parameter.  The JobSchedulerPLSQLJob can be used to execute existing PL/SQL files just by referring them in the command parameter. 

...

It strongly recommend that a db_connection parameter file such as database_connection.parameter.xml is used to store all the database connection settings in a common location. This approach enables the user to manage settings at central location and which can then be reused by multiple jobs.

...

PL/SQL code can be defined directly inside the Job xml as value of a command  parameter value but is generally better stored on the file system. JITL jobs can be configured to read PL/SQL scripts from the file system by defining the script path as a value for the command  parameter i.e. 

In Following the following example the PL/SQL code is save at saved to the filesystem in C:\app\executables\plsql\get_order_date.sql and subsequently refereed by referenced using the command  parameter.

Passing

PL/SQL

...

results to subsequent job steps as parameters

JobScheduler jobs can create and update JobScheduler Order parameters. The JobSchedulerPLSQLJob  can also pass on the result of PL/SQL execution i.e. calculated dates, parameters calculated from tables, etc. By default the JobSchedulerPLSQL job defines a regular expression to parse dbms_output from the execution of PL/SQLs and sets order parameters for subsequent job steps. For example, the DBMS_OUTPUT.PUT_LINE('SET order_date IS '|| v_order_date) dbms ouput  displays the output on console; if  SET order_date is 20140915, it will be parsed by regular expression ^SETs+(\\s)\\s*ISs(.*)$ and return the order_date="20140915" order parameter All dbms_output statements matching the ^SETs+(\\s)\\s*ISs(.*)$ regular expression will be set as order_parameters.

Return parameters created by JobSchedulerPLSQLJob

Standalone PL/SQL Jobs

If PL/SQL code needs to be parameterized by a job parameter the syntax for parameter substitute is different compare to order jobs.

Since the syntax of suffixing an order parameter for SCHEDULER_PARAM is not required the parameter name can directly be substituted in the PL/SQL code.

See the following example for two variant for standalone PL/SQL code.
