摘要： A server side connection pool provides pooling of server connections. Thus, client side processes do not create groups of dedicated resources. Clients are provided the capability to communicate to a server side connection broker process to GET a pooled server connection comprising connection state plus a thread of execution for doing some work, whereby requesting the work can bypass the connection broker process and go directly to the assigned pooled connection. Once the client issues a RELEASE to release the pooled connection back to the pool, a completely different client process on potentially a different client middle tier machine can reuse the same pooled connection. The server-side connection pool can be logically partitioned into sub-pools that correspond to connection classes that typically correspond to respective applications. A client process can request a pooled connection having a particular state, where a stored procedure can be executed to generate such state.

摘要： Enhanced access data available in a cache. In one embodiment, a cache maintaining copies of source data is formed as a volatile memory. On receiving a request directed to the cache for a copy of a data element, the requested copy maintained in the cache is sent as a response to the request. In another embodiment used in the context of applications accessing databases in a navigational model, a cache maintains rows of data accessed by different user applications on corresponding connections. Applications may send requests directed to the cache to retrieve copies of the rows, populated potentially by other applications, while the cache restricts access to rows populated by other applications when processing requests directed to the source database system. In another embodiment, an application may direct requests to retrieve data elements caused to be populated by activity on different connections established by the same application.

摘要： In transferring data from/to a database server, the size of a network buffer used by a network layer is dynamically adjusted according to the call type and expected size of data to be transferred for the call. Due to such use of appropriate buffer size, throughput performance of the transfer may be enhanced.

摘要： A net traffic optimization method provides for clients and servers to communicate with each other over a busy network. Each client process will make an Oracle database service request that is recognized by a listener process in the servers. As each database instance comes up, it generates a globally unique instance identifier (“UII”). Each UII remains valid as long as the database instance that generated it is running. The same UII identifier is given to every client needing a connection to that particular instance. Client processes can simultaneously or sequentially connect to database instances, and must never see the same UII being used to identify two different instances.

摘要： An aspect of the present invention simplifies the implementation of custom atomic transactions. A program logic (implementing a custom atomic transaction) may request a unique transaction identifier from a programming environment. The program logic may then specify a task procedure, corresponding roll-back procedures, and the transaction identifier using an interface provided by the programming environment. The programming environment keeps track of the specified roll-back procedures. The information maintained by the programming environment may be used to execute the roll-back procedures if the atomic transaction is to be aborted. As the programming environment keeps track of the roll-back procedures to be executed, the implementation of atomic transactions may be simplified.
