  - flush
```
public void flush()
```
    This method flushes all dirty, new, and deleted instances to the datastore. It has no effect if a transaction is not active. If a datastore transaction is active, this method synchronizes the cache with the datastore and reports any exceptions. If an optimistic transaction is active, this method obtains a datastore connection and synchronizes the cache with the datastore using this connection. The connection obtained by this method is held until the end of the transaction.
    
    Specified by:
    
    flush in interface javax.jdo.PersistenceManager
  - checkConsistency
```
public void checkConsistency()
```
    This method validates the cache with the datastore. It has no effect if a transaction is not active. If a datastore transaction is active, this method verifies the consistency of instances in the cache against the datastore. An implementation might flush instances as if flush() were called, but it is not required to do so. If an optimistic transaction is active, this method obtains a datastore connection and verifies the consistency of the instances in the cache against the datastore. If any inconsistencies are detected, a JDOOptimisticVerificationException is thrown. This exception contains a nested JDOOptimisticVerificationException for each object that failed the consistency check. No datastore resources acquired during the execution of this method are held beyond the scope of this method.
    
    Specified by:
    
    checkConsistency in interface javax.jdo.PersistenceManager
  - getSequence
