Determines whether the Teradata Intelligent Memory (TIM) cache preload task is enabled.
When enabled, the TIM preload task loads the most frequently accessed data into the TIM cache (a portion of FSG cache) during system startup, after the logons-enabled stage. This allows faster access to this data.
|TRUE||TIM preloading task is disabled.
Data is not preloaded into cache during Teradata system startup.
|FALSE||TIM preloading task is enabled.
TIM preloads the most frequently accessed data into FSG cache during system startup. This is the default.
Changes Take Effect
During the next Teradata system restart.
Frequency of data access is monitored by Vantage. Cylinders containing the most frequently accessed data are designated to have a data temperature of VERYHOT. These cylinders are loaded into the TIM cache during system startup.
