POSIX.1h SRASS and POSIX.1m Checkpoint Restart
Helmut Roth <hroth@ nswc.navy.mil> reports on the April 1999 meeting in Charlotte, NC.
The POSIX.1h Services for Reliable, Available and Serviceable Systems, (SRASS) and POSIX1.m Checkpoint Restart working groups are in the process of developing a set of APIs for fault management and serviceability applications. The goal of the SRASS Working Group is to support fault-tolerant, serviceable, reliable, and available systems in a useful, portable way. Where feasible, POSIX.1h also needs to be useful for general applications such as distributed parallel database transaction systems and safety-related systems. The work of Checkpoint Restart overlaps this goal, and so the working groups have effectively merged while still producing two separate standards.
The most recent Checkpoint Restart ballot achieved 59 percent approval, and the Working Group is currently resolving ballot objections and revising the draft. It is hoped that the next draft will be out for recirculation soon.
The SRASS document contains several groups of interfaces:
The working group has yet to finalize the changes in the SRASS draft (draft 4.0). Additional meetings were planned for early June to finish ballot resolution on the previous draft and to get draft 4.0 completed.
