What are the differences between CALL TRANSACTION and BATCH INPUT SESSION ?

- The most important aspects of the batch session interface are:
- Asynchronous processing
- Transfers data for multiple transactions
- Synchronous database update

During processing, no transaction is started until the previous transaction has been written to the database.
- A batch input processing log is generated for each session
- Sessions cannot be generated in parallel

The most important aspects of the CALL TRANSACTION USING interface are:
- Synchronous processing
- 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.
- No batch input processing log is generated
