These differences are explained in the following sections. 1.1 Compatibility DECwatchdog/Autopilot 2.1 is not compatible with previous versions, Earlier versions must be disinstalled from the system before installation of DECwatchdog/Autopilot 2.1. The configuration file and script files must be modified and renamed according to the mission name (see the examples in the DECwatchdog/Autopilot Installation Guide). 1.2 New Features 1.2.1 Stop and Start Commands o There are new Stop and Start commands, which with the IDLE state, provide "cold and warm start" capability of the mission and thus allow maintenance of the mission, o DECwatchdog/Autopilot software runs on distributed configura- tions running the following operating systems: o OSF/1, o ULTRIX/RISC, o OpenVMS VAX, o OpenVMS AXP and o Windows NT. Introduction 1-1 Introduction 1.2 New Features 1.2.2 User Interface Some commands have been renamed. 1.2.3 Configuration files Two configuration files are now used by the watchdog process: o the mission file, o the local file. These files are mandatory on all the nodes of the mission. The mission file must be the same on all the nodes of the mission, and contains all the necessary information for the messages exchange. The local file can be different from one system to another, and contains the name of the script files that are triggered by events. It also contains the triggering conditions for the EVENTSCRIPT. 1.2.4 Node priority In the mission file, a new parameter called "priority" is used by the lock protocol to allocate the MASTERTOKEN. The node with the highest priority is the prefered node to lock the MASTERTOKEN. 0 is the highest priority level. 1.2.5 Satellite license A license is now necessary for a satellite node. 1.2.6 Eventscript The eventscript triggering depends on the triggering condition that is enabled or disabled in the local file. 1.2.7 Network failure The localization of network failures has been improved when more than two nodes with two interfaces per node are used for a mission. 1-2 Introduction Introduction 1.3 Known Problems 1.3 Known Problems Before starting the watchdog process at boot time, the .dat files located in the watchdog directory must be deleted.
