Setting up an Oracle-Only Backing Store : Oracle-Only Backing Store Runtime Behavior

Oracle-Only Backing Store Runtime Behavior
During regular operation, cache data is written to the backing store by the cache cluster.
With write-behind database writes management, only cache servers write to the backing store. Inference agents and query agents are not involved in writes to the database.
At system startup, the data is loaded into the cache from the backing store, using any one of the nodes (including nodes running inference agents and query agents).
Options to configure these behaviors are explained next.
Reading From the Backing Store at Startup
At system startup, after the minimum number of cache servers have started, the cache is loaded with backing store data. This occurs before the agents begin to process events or execute startup functions.
You can configure the system so that only certain objects are loaded into the cache from the backing store at startup. See Cluster Tab — Cache OM — Domain Objects Settings.
Reading From the Backing Store At Runtime
At runtime, if an object is not in working memory it is requested from the cache. If it is not in the cache, the cache server retrieves that object from the backing store.
At runtime, only the cache servers interact with the backing store.
Writing to the Backing Store
After an RTC, data is written to the cache, and then the cache writes the data to the backing store.
