The Java transaction API for use with global transaction can use a system using alias for the branch ID. The alias can allow multiple branch IDs for single resource.

Method and assignment of transaction branches by resource name aliasing

A connection pool can use a credential mapper to map credentials for an application server into a credential to use with the database management system. This can allow objects such as an Enterprise Java Bean to access the database with more specific credentials than the anonymous connection pool connection user name/password.

Credential mapping of WebLogic and database user ids

A Rowset can sort the order of rows of without requiring resorted data be obtained from the database.

Sorted rowset

A transaction context can be used to select a single database instance for global transaction to prevent lockout or other data problems from the database system with multiple data instances.

Use of transaction context to select single database instance for global transaction

Multiple Shared Rowsets, can access rows of data stored in a Cached Rowset independently. These Shared Rowsets can have their own cursor, sorted order, filtered rows, and pending changes.

Shared rowset

A dynamic generated wrapper object to intercept transmissions between a vendor object and an application program and performs server side tasks. To dynamically generate the wrapper at runtime in memory, the application server receives a vendor class, performs reflection on the vendor class, generates a wrapper class, and creates an instance of the wrapper class. In operation, the dynamically generated wrapper object receives a call placed to a method of the wrapped object, initiates pre-processing tasks to be performed, calls the method on the wrapped object, receives a result from the method invocation against the wrapped object, initiates post-processing tasks to be performed, and transmits the wrapped result back to the application program. The pre-processing tasks may include execution of a pre-invocation handler. The post-processing tasks may include execution of a post-invocation handler.

A retry period can be used in a system that uses a first and second database instance to ensure that the status information from the first database instances has been transferred and updated at the second databases instance.
