dear sir/ madam
this is mallikarjuna shastry, currently pursuing the
Ph.D in fault tolerance in distributed systems.
i am dealing with analysis of roll-back recovery
protocols such as checkpointing and message logging.
i have installed blcr-0.5.5 on my linux 9 system.
each time i switch off my system i have to reinstal
blcr and run the commands like cr_run,cr_checkpoint
and cr_restart otherwise they do not work.
what my be the problem with this? and how do i
overcome this?
plz advise me in this regard.
i have the folowing queries.
1. how do i take the periodic checkpoint on a process
?
2. hod do i restart a process on another node after
taking checkpoint and terminate it(process-migration)
3. does blcr support co-ordinated blocking checkpoint
protocol or non-blocking co-ordinated checkpoint ?
4. how do i implement the protocols like
a.unco-ordinated checkpoint ?
b.communication indeced checkpoint ?
c.message logging protocols such as pessimistic,
optimistic and causal protocols.?
kindly send the details regarding this and advise me
how do i proceed further.
regards
m.shastry
