New Batch Job

This section describes the functions of the New Batch Job wizard.

Depending on the batch Job type (chunked, tasklet) and the batch Reader/Writer type (File, DB, etc.), it automatically generates batch bean, DBIO, and Job Config files.

There are two main types of batch Jobs.

Batch Job Type Description

Batch Job Type	Description
Tasklet	Used for simple DB CRUD operations or batches that must be committed/rolled back at once.
Chunked	Defines and uses an `ItemReader` that receives input one item at a time from a DB or file, an `ItemProcessor` that processes the business logic one item at a time, and an `ItemWriter` that outputs the result.

Tasklet

Used for simple DB CRUD operations or batches that must be committed/rolled back at once.

Chunked

Defines and uses an ItemReader that receives input one item at a time from a DB or file, an ItemProcessor that processes the business logic one item at a time, and an ItemWriter that outputs the result.

Run the New Batch Job wizard as shown in the figure below.

Click New → 'New Batch Job' in the Quick menu at the top left.

Select New Batch Job menu

1. Tasklet

Used for simple DB CRUD operations or batches that must be committed/rolled back at once.

Select the Tasklet type, enter the job ID, and click Next.

At this time, the step ID and shell name are auto-completed by a module defined by the framework administrator.

(1) Select Tasklet type
(2) Enter Job ID and Step ID
(3) Select whether to generate a shell script and enter the shell name
(4) Click Next
Enter the package, type, and logical name.

At this time, the package, type, and logical name are auto-completed by a module defined by the framework administrator.

(1) Enter the package, type, and logical name
(2) Click Next

2. Chunk

Select the Chunked type, enter the Job ID, and click Next.

At this time, the step ID and shell name are auto-completed by a module defined by the framework administrator.

(1) Select Chunked type
(2) Enter Job ID and Step ID
(3) Select whether to generate a shell script and enter the shell name
(4) Click Next

Select the type, input package, type, and logical name of the Reader; select whether to use the Processor; select whether to use the Writer, its type, output package, type, logical name, and data source; then click Next.

At this time, the package, type, and logical name are auto-completed by a module defined by the framework administrator.

(1) Select Reader type

Reader Type Description

Reader Type	Description
Database	Used when querying batch target data using DBIO.
Fixed	Used when reading a fixed-length file.
Delimited	Used when reading a file defined with delimiters.
MultiType Fixed	Used when reading a file with a Header/Body/Footer structure of fixed length.
MultiType Delimited	Used when reading a file with a Header/Body/Footer structure defined by delimiters.
Variable	Used when reading a file line by line in string format. (IO is not defined because it is passed to `ItemProcessor` as a `String`.)
File Read Source(Fixed)	Used when reading a fixed-length file implemented in source code.
File Read Source(Delimited)	Used when reading a file defined with delimiters implemented in source code.

(2) Enter input type package, type, and logical name
(3) Select whether to use Processor and its options
(4) Select whether to use Writer and its type

Writer Type	Description
Database	Used when inserting/updating/deleting result data using DBIO.
