    Abstract: A system and method for transparent multi key-value weighted attributed connection using uni-tag connection pools. In accordance with an embodiment, a connection pool enables labeling of connections that software applications can use to access a database. A connection pool associated with a database enables tagging of connection pools at the database and allows applications to selectively obtain connections based on tags. A request is received from an application to query data from the database using a labeled connection or low-cost alternative. If a low-cost connection is found, but requires configuration, the system returns unmatched labels for use by the application in configuring its environment to use the connection. The system can also generate a tag for the connection. Upon subsequent release of the database session, the tag can be made available for subsequent use of the tag, or a tagged connection, by the same or by other applications.

    Abstract: In accordance with an embodiment, a system enables multidimensional search within a resource pool, to support complex borrow operations such as, for example, specifying ranges for particular connection properties. As threads access the pool, attempting to borrow connections having particular connection properties, one or more skipped pool elements can be represented as skip lists within a k-dimensional tree (KD-tree) or other data structure that enables searching across multiple dimensions. In response to receiving a request to borrow a connection having particular connection properties, a multidimensional search can be performed within the KD-tree to determine the availability of a connection having the requested properties.

    Abstract: In accordance with an embodiment, described herein is a system and method for row buffering in a database environment. A transparency engine can be provided between client applications and a database, and can operate as a proxy engine for the database and as a session abstraction layer for the client applications, to enable the client applications to utilize database features provided by the connection pool without code changes to the client applications. The transparency engine can maintain a plurality of local row buffers to store rows fetched from a database. The local buffers can be filled by rows pre-fetched from the database. When a client application requests rows from the database, the transparency engine can first check whether the rows exist in a local buffer. If the rows are present in the local buffer, the transparency engine sends the rows to the requesting client application, without going to the database.

    Abstract: Transactional and non-transactional data for maintaining session state is described. In a session, a server instance receives, from a client, a request to execute transactional commands and non-transactional commands. The server instance sends at least one first directive executable at the client to store, in a first set of information, one or more first items representing one or more particular transactional commands that are open but not yet committed. The first set of information is maintained separately from a second set of information including one or more second items representing one or more particular non-transactional commands that have been processed. Based on committing one or more particular transactional commands, the server instance sends at least one second directive executable at the client to purge, from the first set of information, the one or more first items without purging, from the second set of information, the one or more second items.
