Recovery
Recovery from throttle mode is automatic, as soon as the background evictions have time to reduce the data set to within its limitations.
If the TSA enters restricted mode, operator events will be logged in the TMC, and user or programmatic intervention is necessary. In the TMC, you can initiate actions to manually reduce the data set. You can also anticipate operator events and use programmatic logic to respond appropriately.
The following actions are recommended for reducing the data set:
Clear caches (from the TMC or programmatically)
Remove entries from data sets programmatically
Note:
Because eviction in restricted mode is resource-driven, changing TTI/TTL or maximum capacity will not move the TSA out of restricted mode.
To clear caches from the TMC, click the Application Data tab and the Management sub-tab. Each cache will have a clickable option to Clear Cache. Note that caution should be used when considering whether to clear a pinned cache.
