Abstract: The method and apparatus for maintaining active sessions between communicating logical units (10, 40) in a computer network when an application system fails without having to re-establish the active sessions, are carried out by activating a persistent session capability at one of the logical units. Thus, the active sessions can be suspended and maintained while attempts at recovery are made. Recovery attempts include restarting the failed application or switching the suspended sessions to an alternate instance of the logical unit (10). The suspended sessions are re-synchronized with the application system and session activity is resumed.
