In accordance with an embodiment, described herein is a system and method for use of lock-less data structures and processes with a multidimensional database computing environment. Lock-less algorithms or processes can be implemented with specific hardware-level instructions so as to provide atomicity. A memory stores an index cache retaining a plurality of index pages of the multidimensional database. A hash table indexes index pages in the index cache, wherein the hash table is accessible by a plurality of threads in parallel through application of the lock-less process.

System and method for use of lock-less techniques with a multidimensional database

In accordance with an embodiment, described herein is a system and method for use with a multidimensional database computing environment. Particularly, a system and method are described for performing in-place data writes to a data storage medium associated with the multidimensional database computing environment. For example, when multiple data updates from calculation scripts are associated with a same set of blocks, the in-place data enable the system to reduce fragmentation of the data storage medium, and also to reduce contention due to index updates.

The present invention is related to a method for communicating features supported by a device to at least one other device. The method includes providing a bit stream by the device, where at least one bit in the bit stream represents a feature supported by the device. In a second aspect, a method for establishing a communication session between at least two devices includes initiating communication between a first device and a second device, exchanging a bit stream associated with the first device and a bit stream associated with the second device, and identifying mutually supported features.
