Abstract: Techniques for migrating duration trees from a source database server (or instance) to a destination database server (or instance) are provided. A duration is a memory management construct that allows database components to group related areas of memory together. A source duration tree is captured at the source database server and combined with a destination duration tree at the destination database server. Any duration identifiers in the source duration tree that conflict with (i.e., are the same as) a duration identifier in the destination duration tree are mapped to new duration identifiers.

Abstract: A distributed code development environment includes baseline code that is logically divided into a plurality of labels, each including a plurality of transactions authored by respective developers. A computer-implemented method for identifying intermittent errors in the baseline and determining whether errors generated by a test of transactions are intermittent or consistent may include steps of providing the baseline code and providing the plurality of transactions, each of the plurality of transactions including code authored by a developer. A selected test may be carried out on a selected one of the plurality of transactions, the selected test generating an error that represents an unsuccessful completion of the selected test. The generated error may then be compared against errors generated by the selected test on other transactions or labels.

Abstract: Disclosed is a system and method for improving the performance of marshalling and un-marshalling operations. In one approach, the system and method can be used to improve the performance of marshalling and un-marshalling operations in databases that support opaque types. The system and method is configured to allow aggregated objects to share data within the contexts. The described approach can also be used for other types of processing of a hierarchy of objects not involving marshalling and un-marshalling.
