An arrangement is provided for generating an error chain in a call stack. A function is invoked to perform a functionality. If an error occurs during performing the first function, errors including the ones contained in an error chain, created based on at least one context specific error state and represented by an error tokan, and the error, occurred during said performing the functionality, are processed. The function then returns to another function that invokes it either with a new token error token representing a new error chain containing the error occurred and the errors contained in the error chain or with an error status. If the function does not error, it returns a normal status to the other function that invokes it.

Providing a chain of tokenized error and state information for a call stack

A distributed reader and writer's lock to synchronize object management systems is disclosed. The purpose of the lock is to control access to information that is shared by corresponding object management system components on multiple object management systems. An object management system is a computer-based system for storing, naming, and manipulating objects. One lock is created for each object management system component associated with a particular service within the system. The locks communicate over an interface definition language interface. The reader/writer's lock is created by a remote component synchronization module, which acts as an agent for the object management system component. The lock exposes functions to request or release a write lock and to request or release a read lock.
