TRANSACTION_ROLLED_BACK_STATE_CWOBJ0066W=CWOBJ0066W: The {0} transaction has been marked rollback-only due to a state change of ObjectGrid {1} on shard {2} that forced transaction completion. This might be caused by an administrator changing the availability state of the ObjectGrid instance or termination of the ObjectGrid instance.
Explanation
eXtreme Scale automatically marks a transaction rollback-only when it does not end normally during some instances. When an administrator needs to quiesce activity to bring the data grid into the offline or preload state, if the transaction does not end normally in the allowed time, the transaction is marked rollback-only.
User response
The administrator must wait for a period of inactivity to change the state of the data grid. Alternatively, you can manually end or put client applications and their transactions into an inactive state before you change the state of the data grid.
