What is JDBC Adapter Notification :
JDBC Adapter Notification in webMethods is like a smart messenger between the webMethods Integration Server and databases. It keeps an eye on the database for any changes and quickly tells the Integration Server about them. This helps keep everything in sync, making work smoother and more efficient.
Let’s use a real-life scenario: Think about when you sign up on a website using your email. Your info goes into the website’s storage. If there’s a special alert for new sign-ups, it can grab your info and send you a welcome email automatically, this can be achieved using the notification.
JDBC Adapter Notification Types :
- InsertNotification : It is an Adapter Notification template that focuses on capturing and responding to database insert events. It allows webMethods Integration Server to actively monitor a database table for any new record insertions. As soon as a new record is added to the specified table, the Insert Notification feature triggers predefined actions or notifications within the Integration Server. This capability is particularly useful for real-time data integration and event-driven communication, ensuring timely responses to database updates and facilitating seamless data synchronization between different systems.
- UpdateNotification : It is an template that enables real-time notifications for database table updates, allowing webMethods Integration Server to respond promptly and automate actions based on the updates.
- DeleteNotification : It is a template that sends real-time alerts to webMethods Integration Server when records are deleted from a database table. It helps keep the Integration Server updated and enables immediate actions in response to data deletions, ensuring smooth data management.
- BasicNotification : BasicNotification is a simple and straightforward mechanism for setting up event-driven communication, ensuring that Integration Server can respond quickly to changes in the external system, enabling efficient data synchronization and seamless integration between various applications and databases.
- StoredProcedureNotification : StoredProcedureNotification in webMethods adapter is a template that allows webMethods Integration Server to subscribe to changes in a database using stored procedures. It enables real-time communication between the Integration Server and the database, and when a predefined condition is met, the stored procedure is executed, triggering immediate actions or notifications
- OrderedNotification : OrderedNotification in webMethods Adapter is a template that maintains the proper sequence of database change notifications, even when multiple events occur simultaneously. It ensures data consistency and prevents conflicts by processing notifications in the order they were received.
- StoredProcedureNotificationWithSignature :The “StoredProcedureNotificationWithSignature” template allows you to invoke a stored procedure in the database and publish a notification based on its outcome, using the provided configuration signature.
Basic Notification Vs Other Notification(Insert/Update/Delete) :
| Basic Notifiction | Other Notifiction |
|---|---|
| It refers to a type of notification that triggers an action or event when any change (insert, update, or delete) occurs in a specified database table. It is a generic form of notification that captures all types of changes. | (Insert, Update, Delete) are more specific and granular. They trigger actions or events only when a particular type of change happens in the database table |
| Offers greater control to users and DBA, but they require additional effort as the setup involves creating an appropriate buffer table, trigger, and sequence manually.
| Automatically generates the required database objects such as buffer table, trigger, and sequence. |
| Suitable for scenarios where you need a global view of all changes in the table and where uniform handling of all changes is required. | Ideal when you need to perform specific actions for each type of change, tailored to the unique requirements of insert, update, or delete operations. |
Prerequisite :
- A database must be installed and configured appropriately.
- Ensure that you have completed the JDBC configuration in the integration server. Click here to access the article on how to perform the JDBC configuration.
- Prior knowledge of creating a JDBC adapter in webMethods is required for this task, for a comprehensive guide, you can click here to access the article.
- The user you’ve set up in the JDBC connection must possess the necessary privileges to create both the buffer table and triggers. This is important because our integration server will create these components automatically for the adapter notifications.
