摘要: 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 sessions, are carried out by activating persistent session capability at one of units. Thus, can be suspended maintained while attempts recovery made. Recovery include restarting failed applica­tion or switching alternate instance unit (10). re-synchronized with ses­sion activity is resumed.
