ABSTRACT:
A method and apparatus for asynchronously storing transaction information related to a transaction is provided. A client process executing on a client may initiate a transaction request with a server. The server processes the transaction, commits the transaction, and writes transaction information associated with the transaction to memory without durably storing the transaction information. Thereafter, the server processing the transaction returns a message to the client that the transaction has been committed. A server process, which performed the transaction, may be reassigned to commit new work. Additional information that may be useful for the client about the result of the transaction may be contained in the message. Next, transaction information stored in memory is durably stored. A log writer may be used to durably store the transaction information to a log file. The client is subsequently notified that the transaction information has been durably stored at a client listening process.
