ABSTRACT:
An apparatus, system, and method are provided for sharing a cached security profile in a database environment. The apparatus, system, and method include a cache module for caching a security profile accessible to primary tasks and secondary tasks. An identification module is provided that distinguishes between primary tasks authorized to refresh the security profile and secondary tasks. A refresh module cooperates with the cache module and identification module to selectively refresh the security profile in response to a refresh request and expiration of the security profile such that an old version of the security profile is retained for use by secondary tasks until an execution window closes.
