Custom Batch Subscription

Use this type of subscription to deliver data when you want to use a

Data Integration Hub

batch workflow that the developer created in the

Data Integration Hub

Operation Console. Batch workflows run according to a trigger and not continuously.

A custom mapping uses a PowerCenter workflow, a Data Engineering Integration mapping or workflow, or a Data Quality mapping or workflow to consume data. Workflows and mappings can perform complex transformations on the data.

When a custom mapping uses a PowerCenter workflow, the developer creates a workflow in PowerCenter Designer. When a custom mapping uses a Data Engineering Integration mapping or workflow or a Data Quality mapping or workflow, the developer creates a mapping in Informatica Developer. The developer then imports the workflow or the mapping to a

Data Integration Hub

workflow. You select the

Data Integration Hub

workflow when you create the custom subscription in

Data Integration Hub

The

Data Integration Hub

workflow includes information about the target data structure and the database connection.

To create a custom batch subscription, select a

Data Integration Hub

workflow that reads from topic tables and writes to the target. Workflow sources must include at least one of the topic tables, and must not include any source table that is not defined in the topic.

If a PowerCenter workflow, a Data Engineering Integration mapping or workflow, or a Data Quality mapping or workflow includes parameters, you can enter values for the parameters in the Subscription wizard. The developer imports the workflows and mappings to

Data Integration Hub

with the parameter definitions.

When you create a custom batch subscription, you can create a compound subscription, where the subscription consumes data sets from multiple topics of the same type. The subscription process starts after all publications from all mandatory topics publish data. You can specify the maximum time to wait for all publications to finish publishing, from the time the first publication is ready to consume.

The following pages appear in the subscription wizard for this type of subscription:

General. Define basic subscription properties.

Processing. Select the subscription mapping. If you use file transfer, select the connection to the target to which

Data Integration Hub

writes the files. If you want to run a post-process on the subscription, select a subscription post-processing workflow.

The content of this page depends on the PowerCenter workflow, Data Engineering Integration mapping or workflow, or Data Quality mapping or workflow parameters that the developer defines. The developer imports the workflow or the mapping to

Data Integration Hub

and determines the layout of the page. Post-processing parameters are optional. If required, set the values of the parameters.

Schedule. Define the method and the frequency of data consumption. You can select to consume the published data immediately after the data is ready, to run the subscription manually or by an external trigger, or to consume the data according to a schedule that you define.

Permissions. Assign categories that restrict access to the subscription. You can assign permission to a subscription only if the associated application has assigned categories. If you do not assign categories to the subscription, it inherits the categories from the associated application. If there are no categories assigned to the application, all

Data Integration Hub

users can access the subscription.

Summary. Review the subscription settings and save the subscription.
