Freshness and update consistency: There are many possible ways of propagating updates from the data origins to intermediate nodes that have materialized views of this data. Some possible solutions would be invalidation messages pushed by the server or client-initiated validation messages; however, both of these incur overhead that limits scala- bility. Another approach is a timeout/expiration-based protocol, as employed by DNS and web caches. This approach has lower overhead, at the cost of providing much looser guarantees about freshness and consistency. Still, this is much stronger than what P2P currently gives us, which is no guarantee at all. It should not be surprising that the data. | Interested in learning more about securing Oracle SANS Institute Security Consensus Operational Readiness Evaluation This checklist is from the SCORE Checklist Project.

This checklist is just that a checklist and does not contain any specific SQL or shell commands because it is intended to be just a list rather than a how to document otherwise. It is also important that the Oracle database is not checked in isolation and the surrounding elements such as the operating system used the network configuration web access application servers and clients are considered. Whilst every effort has been made to ensure that this checklist is as complete and comprehensive as possible new issues and vulnerabilities are found every day therefore don t rely on it to be all encompassing. Regularly check for updates of this list. Elements to be considered prior to applying this checklist Host Operating System - Although this checklist includes items that specifically relate to the operating system hosting the Oracle installation they are included because they have a direct effect on Oracle. It is imperative that the host operating system is secured before any applications in this case Oracle . The same applies to network components and .
