===== 7.8 Commit Capacity =====

Because platform resources are limited, the number of bytes of conditionally updated data that can be accumulated during a transaction is limited. The Java Card technology provides methods to determine how much**// commit capacity//** is available on the implementation. The commit capacity represents an upper bound on the number of conditional byte updates available. The actual number of conditional byte updates available may be lower due to management overhead. 

A **TransactionException** is thrown if the commit capacity is exceeded during a transaction.
