What is the automatic commit mode in DB2?

In DB2, the automatic commit mode is a configuration option of the database management system that determines whether database operations are automatically committed when executed. When automatic commit mode is enabled, each SQL statement is automatically committed after execution, even if multiple SQL statements are executed within a single transaction, each operation will be committed separately instead of being batched in a single transaction.

Enabling automatic commit mode is beneficial for simplifying operations and reducing the likelihood of errors, but it can also potentially increase performance overhead as each operation has to be committed, potentially increasing the I/O operations on the database. Therefore, in practical application, it is necessary to choose whether to enable automatic commit mode based on specific circumstances.
