Cache Tables Managed by the Data Object Cache Manager
Cache Tables Managed by the Data Object Cache Manager
By default, the Data Object Cache Manager manages the cache tables in the data object cache database.
When the Data Object Cache Manager manages the cache tables, you can perform the following operations on the data object cache:
Refresh the cache
You can refresh the cache for a logical data object or virtual table according to a schedule or manually. To refresh data according to a schedule, set the cache refresh period for the logical data object or virtual table in the Administrator tool.
To refresh the cache manually, use the infacmd dis RefreshDataObjectCache command. When the Data Object Cache Manager refreshes the cache, it creates a new cache. If an end user runs a mapping or queries an SQL data service during a cache refresh, the Data Integration Service returns information from the existing cache.
Abort a refresh
To abort a cache refresh, use the infacmd dis CancelDataObjectCacheRefresh command. If you abort a cache refresh, the Data Object Cache Manager restores the existing cache.
Purge the cache
To purge the cache, use the infacmd dis PurgeDataObjectCache command. You must disable the application before you purge the cache.
