Customer's application was configured to run on 4 separate TimesTen data stores with an identical set of autorefreshed read-only cache groups on each data store. The base tables for all of the cache groups resided on a single Oracle database.

Customer reported that none of the cache groups on any of the 4 data stores were refreshing properly. Customer subsequently determined that any operation attempted by the cache agent hung.


-no changes were made on any of the TimesTen data stores.

-some invalid kernel parameter changes may have been enabled on the Oracle database.
