System automatically updates a list of tables being cached both totally rely on data monitoring to maintain the cache information current.
Contextr name is P2K_CTX and is create by the DB_CEATE_CONTEXT script.
Data Cache - we cache everything from countries to people's current effective records - is loaded on first use and is threaded. For example, if I have 55,0000 assignment details and I request for a specific record, the system will start loaded the cache, but will also do a direct read on the data so as to minimize the apparent impact of the performance.
Business Object Cache this can be seen in VMBC - Concept - it is more than just raw data, but is an intelligent gathering of data (for example, LOVs - which groups data and other business objects together)
Is Monitored - is a derived column that starts from the IMTD toggle, but may be turned on if the data is in use by a user. As the system is used more and more, there are more tabes that will be turned on as being monitored, whether they are cached or not.
A table that is cached must also be monitored.
Performance - Logging - first thing to think about is logging.
