What is the formula used by TimesTen to detect if a row should be aged? (Doc ID 1081250.1)

Last updated on JUNE 05, 2019

Applies to:

Oracle TimesTen In-Memory Database - Version and later
Information in this document applies to any platform.


TimesTen allows rows to be 'AGED' - either in a regular table, or within a cache group.

The aging policy you define can be usage based (LRU) or Time Based. This note will discuss Time Based aging.

Time-based aging removes data from tables / caches based on the user specified 'lifetime' and frequency (cycle) of the aging process. You can define both usage-based aging and time-based aging in the same data store, but you can define only one type of aging on a specific table.

This note seeks to answer what formula is used to determine if a row should be 'AGED' when time based aging (rather than LRU based aging) is in use.
