Computer program, computer, and messaging system for returning a data item to a requestor

摘要

The invention relates to an apparatus and a system for returning a data item to a requestor. (The requestor may for example be a systems application.) A request is received to access a data item having data contents of uncertain state (i.e. because the data item is pending completion of a transaction.) The apparatus or system obtains the data item contents and an indication of the state (e.g. delete_on_commit) of the data item contents. This information is then returned to the requestor.
