Abstract: Systems (100) and methods (200) for managing transactional processing. The methods involve executing a first transaction (120) which is blocked by an exclusive lock of at least one second transaction (110) from accessing at least one resource of a system. Thereafter, a determination is made as to whether a Service Level Agreement (“SLA”) associated with the first transaction is being met. If it is determined that the SLA is not being met, the resources needed by the first transaction are identified. Subsequently, all executing transactions, that are using the resources needed by the first transaction, are identified. At least one of the identified transactions is then dynamically slowed down or speed up. The transaction is slowed down or sped up by: adjusting how many records are to be processed in each sub-transaction of the transaction; and/or increasing or decreasing the time period between commit operations of the transaction.
