Using Autonomous Transactions
The transaction is a sequence of SQL statements that does a logical unit of work. Frequently, one transaction starts the other. In several applications, a transaction should operate outside the scope of the transaction that executed it. This can happen, for e.g. If a transaction calls out to a data cartridge.
An autonomous transaction is an independent transaction started by the other transaction, the main transaction. The Autonomous transactions suspend the main transaction, to do the SQL operations, commit or roll back these operations, and then resume the major transaction.
