  • Process and system for obtaining and distributing a ticket identifying a task or event in a multi-node data processing system
    Patent number: 6018795
    Abstract: For the obtainment of a unique number identifier called a ticket indentifying a task or an event in a multi-node data processing system (SYS), a master node (Ny) for distributing the ticket in the system is designated, and it includes a ticket generator (TICKy:VALy, SESSy, COUNTy) whose address (TICK.sub.-- ID) is stored in a reference register (REF) of each node. When a node (Nx) requests a ticket, it reads the address (TICK.sub.-- ID) in this register and thus accesses the ticket generator of the master node (Ny). A backup or substitute node (Ns) can replace the master node (Ny) in case of a failure (TICK-MISS).
