Class Summary |
| BeginXact |
This operation indicates the beginning of a transaction. |
| ConcurrentTransactionMapFactory |
A helper class that enables use of ConcurrentHashMap instead of
Hashtable on platforms that support it. |
| ConcurrentXactFactory |
A TransactionFactory similar to XactFactory, only that it
provides overrides that give access to classes in the java.util.concurrent package, if supported by the runtime environment. |
| ContainerLocking2 |
A locking policy that implements container level locking with
isolation degree 2. |
| ContainerLocking3 |
A locking policy that implements container level locking with
isolation degree 3. |
| D_Xact |
The D_Xact class provides diagnostic information about the Xact class. |
| EndXact |
This operation indicates the End of a transaction. |
| EscalateContainerKey |
|
| GlobalXactId |
|
| InternalXact |
|
| LockCount |
|
| NoLocking |
A locking policy that implements no locking. |
| RowLocking1 |
A locking policy that implements row level locking with isolation degree 1. |
| RowLocking2 |
A locking policy that implements row level locking with isolation degree 2. |
| RowLocking2nohold |
A locking policy that implements row level locking with isolation degree 2,
never holding read locks after they are granted. |
| RowLocking3 |
A locking policy that implements row level locking with isolation degree 3. |
| RowLocking3Escalate |
A locking policy that implements row level locking with isolation degree 3. |
| RowLockingRR |
A locking policy that implements row level locking with repeatable read
isolation. |
| SavePoint |
|
| TransactionMapFactory |
Helper class for TransactionTable which allows it to plug in a
different java.util.Map implementation for the map that contains
all the TransactionTableEntry instances in the transaction table. |
| TransactionTable |
The transaction table is used by the transaction factory to keep track of
all transactions that are in the system. |
| TransactionTable.UpdateTransactionCounter |
Visitor class that counts update transactions. |
| TransactionTableEntry |
Transaction table entry is used to store all relevant information of a
transaction into the transaction table for the use of checkpoint, recovery,
Transaction management during Quiesce state, and for dumping transaction table. |
| Xact |
A transaction has five states
CLOSED - cannot be used
IDLE - no reads have been performed by the transaction. |
| XactContext |
The context associated with the transaction. |
| XactFactory |
|
| XactId |
Use this class for a short hand representation of the transaction. |
| XactXAResourceManager |
The XactXAResourceManager implements the Access XAResource interface, which
provides offline control over two phase commit transactions. |
