  • Multi-level security profile refresh
    Patent number: 7136856
    Abstract: A request is received from a user associated with the client and a transaction aging value is copied to a security aging value associated with the cached user security profile if the transaction aging value is specified with the user request. A decay time is calculated utilizing a profile refresh time stamp associated with the cached user security profile and a system clock. The cached user security profile is then refreshed if a refresh event occurs.
    Type: Grant

  • Method, computer program product, and system for global refresh of cached user security profiles
    Patent number: 7107422
    Abstract: A master dynamic aging value associated with the client is calculated responsive to an operator command to perform the global refresh. When receiving a request from a user associated with the client, a sub-dynamic aging value associated with a cached user security profile for the user is compared to the master dynamic aging value. If the sub-dynamic aging value is not equal to the master dynamic aging value, then the cached user security profile is refreshed.
