Input 

Document

• Min: 1

• Mapper

• Copy

Requires the EDI data and internal ID as a JSON documentboth the Schema name and the Table name to process a specific number of input documents into a prepared insert query and execute all of the prepared input document values on that query as a batch.

The Snap outputs the number of documents successfully inserted into the target table in the output view document.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab:

• Stop Pipeline Execution: Stops the current pipeline execution if the Snap encounters an error.

• Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records.

• Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution. Learn more about Error handling in Pipelines.

Learn more about the behavior of the Oracle - Parallel Load Snap with open error views.

Label*

Default Value: Oracle  Oracle - Parallel Load
Example: Oracle  Oracle - Parallel Load

String

Specify the name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap Snaps in your pipeline.

Schema name

Default Value: N/A
Example: Sys

String/Expression

Specify the database schema name.

Table name*

Default Value: N/A
Example: people

String/Expression

Specify the table on which to execute the load operation.

Create table if not present

Default Value: Deselected

Checkbox

Select this checkbox to automatically create the target table if it does not exist.

• If a second input view is configured for the Snap and it contains a document with schema (metadata) from the source table, the Snap creates the new (target) table using the same schema (metadata). However, if the schema comes from a different database, the Snap might fail with the Unable to create table: "<table_name>" error due to error because of data type incompatibility.

• In the absence of Without a second input view, the Snap creates a table based on the data types of the columns generated from the first row of the input document (first input view).

Maximum thread count*

Default Value: N/A0
Example: people 20

Integer/Expression

Specify the maximum number of threads allowed to perform data insertions simultaneously. If the value is 0, the snap Snap automatically sets the number of threads equal to the number of available processors on the system.

Batch capacity*

Default Value:

1000
Example:

500

Integer/Expression

Specify the maximum number of records allowed in a single batch for an insertion task.

Snap memory usage: To gracefully handle failed record insertions, the Snap must retain some input document data in memory during the Snap execution. To calculate the memory usage follow this formula:
Max thread count * Batch capacity * 2 * typical record size
For example, with a Maximum thread count of 4, a Batch capacity of 10,000, and an average record size of 50 bytes, the input document data in Snap memory might peak at 4 million bytes.

Maximum error count*

Default Value: 50 
Example:10

Integer/Expression

Specify the maximum number of record insertion errors allowed before execution stops on the next error. For example, if you specify a value of 10, the pipeline execution continues as long as until the number of failed records is less than exceeds 10.

Truncate table before load

Default Value: Deselected

Checkbox/Expression

Select this checkbox to truncate the target table before loading data.

Snap Execution

Default Value: 
Example: Validate & Execute

Dropdown list

Select one of the following three modes in which the Snap executes:

• Validate & Execute: Performs limited execution of the Snap and generates a data preview during pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during pipeline runtime.

• Execute only: Performs full execution of the Snap during pipeline execution without generating preview data.

• Disabled: Disables the Snap and all Snaps that are downstream from it.

Pre-load truncation of the target table failed

Either the target table

might not exist

or a database access error

might have occurred when trying to execute the

TRUNCATE statement

.

Verify your database credentials and ensure the target table exists, then

retry.

Unable to determine target table

column names

The connection used to retrieve table metadata

displayed an exception

before closing.

Verify the target table column names and retry.

All insertions committed.

N/A

One document containing the
<insert_count> field with an integer value indicating the number of successfully inserted records.

All input records are successfully inserted into the target database.

Success

One error document for each record that failed to insert.

One document containing the
<insert_count> field with an integer value indicating the number of successfully inserted records.

Some input records individually fail to insert into the target database, but do not exceed maximum error count.

Success

Insertions made successfully
prior to the Maximum
error count being
exceeded may be
committed.

Multiple error documents, one for each record that failed to insert.
The total number of error documents should be
equal to at least the Maximum
error count plus one, but might be more because of concurrency of attempted insertions.

One document containing the
<insert_count> field with an integer value indicating the number of inserted records successfully
before exceeding maximum
error count.

Enough input records individually fail to insert to exceed the Maximum error count and cause the Snap to end execution early.

Success

Insertions made
successfully prior to the
Snap-failing error may be
committed.

One error document for
each record that individually
failed insertion (if any).

One document containing
<insert_count> field with an integer value indicating the number of inserted records successfully before the (Snap-failing) error.

An error occurs beyond the scope of any individual record.

Failure
