CreateEpochAtCommit

For TimesTen Scaleout, specifies if each commit generates an epoch.

Set this general connection attribute to 1 to make every commit from this connection an epoch. The default value is 0, which will make it so commits are not epochs unless the transaction included a call to the ttEpochCreate built-in procedure.

TimesTen Classic ignores this attribute.
