Abstract
Incorporation of a collateral process as a participant in a transaction is made possible by a method and system in accordance with the present invention. Typically, after the transaction is initiated, the collateral process is called and then is registered as a participant,in the transaction. A prepare signal is sent to each registered collateral process when end stage of the transaction is reached. Then, a ready signal is received from the collateral process if the collateral process is completed successfully; and an abort signal is received from the collateral process if the collateral process does not complete successfully or a violation is detected. If a ready signal is received, a commit record is written to a log, and a commit signal is sent to each registered collateral process. In response to the commit signal, a forgotten signal is received from each registered collateral process.
