Abstract
A system uses a resource locking token to allow various processes to have exclusive access to a system resource. The process that receives the token then requests that a local database be updated/synchronized with a master database. The process continues checking the synchronization status every time it gets the token. When the process receives the token and the synchronization is complete, the local database is accessed and the data is used in accessing the system resource. The token is then returned to the system.
