Abstract
Apparatus and method for controlling concurrent process access of infrastructures comprising tree structures of complex object nodes of information. The apparatus and method respond to a request of a computer process by selectively applying a tree lock to a node to lock the node and child nodes located in a tree structure of the tree locked node. Subsequently, the process transports the applied tree lock from the node to selected child nodes located in the tree structure of the node thereby freeing the unlocked node and child nodes thereof for subsequent access by concurrently running ones of the processes.
