Abstract
A process group resource manager for managing protected resources during transaction processing is disclosed. The process group resource manager comprises a first process configured to provide access to a protected resource during one or more transactions, the first process being further configured to construct a transaction record for each respective transaction, wherein each transaction record includes each request message received by the first process and each response message sent by the first process during a particular transaction. The process group resource manager further comprises a second process configured to serially replay the transactions in which the first process participates, the second process being configured to cause a particular transaction to rollback if the replay of that transaction does not match the transaction record constructed by the first process for that transaction. The process group resource manager also comprises a third process configured to store a durable image of the third process for use in reconstructing either the first process or the second process.
