Abstract
A first process in a data grid provides an initial version that corresponds to transaction data controlled by the first to a second process and a third process. The first process receives a request of the second process and changes the transaction data based on a first transaction. The first process provides a current version value of the transaction data to the second process and commit the change to the transaction data based on the first transaction if the current version value matches the initial version value provided to the second process and creates a new version value for the transaction data upon committing the change. The first process changes the transaction data based on the second transaction and rolls back the change made to the transaction data based on the second transaction if the new version value does not match the initial version value provided to the third process.
