HI,

<b>What is the difference between Synchronous and Asynchronous updates</b> ?

- A program asks the system to perform a certain task, and then either waits or doesn't wait for the task to finish. In synchronous processing, the program waits: control returns to the program only when the task has been completed. In asynchronous processing, the program does not wait: the system returns control after merely logging the request for execution.

Reward points if this Helps.

In batch session interface: - Asynchronous processing means Transfers data for multiple transactions - Synchronous database update means during processing, no transaction is started until the previous transaction has been written to the database.

In CALL TRANSACTION: - Synchronous processing means Transfers data for a single transaction. Synchronous and asynchronous database updating both possible The program specifies which kind of updating is desired. Separate LUW for the transaction The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.

Suggest you to Search in SDN with key - Synchronous or asynchronous .

Will get few more useful related Posts.

hi BHASKAR RAO,

The difference is very easy.

Synchronous DB update means immanent, while asynchronous DB update means that it´s done somewhen later.

Somewhen means here: you will not know when, all you know is: "not now".
