    Abstract: A system for managing a cluster of databases that process shared data, the system including a cluster of database nodes, each node including a memory, and a processor configured to, when it is determined that: (i) a lock on a resource is required by a particular node or process, and (ii) no other lock conflicts with this particular lock, send an asynchronous lock taken (ALT) message to a distributed lock manager (DLM); and without receiving a response or permission from the DLM, taking the lock for a resource for the particular node or process.

    Abstract: A method for encoding hierarchical data stored in an index, partitioned into blocks, over keys representing the data. For every key K representing a record R in the index, the key of the children records of record R are prefixed with K. The method includes traversing to a first R record represented in the index, traversing from the record R to the next sequential R such that the path in the index from the position representing R to the position representing the next sequential R does not include information relating to the children of R. Next, repeating the latter operation for 0 or more R records, and for any 0 or more particular R records, traversing from the particular R to its children. The index constitutes a balanced structure of blocks.
