WebCGS, rollback recovery, non blocking. INTRODUCTION Checkpointing with rollback recovery is a well-known method for achieving fault-tolerance in distributed systems. It gives fault tolerance without requiring additional efforts from the programmer. Traditional checkpointing and roll-back recovery algorithms work well in tightly coupled sys-tems. WebFor the rollback scheme developed for multiprocessor systems, closed form expressions for the mean and variance of a task execution time as well as approximate optimal value for the state-save interval are derived. For the rollback recovery schemes developed for distributed processing systems, an algorithm is presented to form numerical solutions.

But later on, T1 fails. So we have to rollback T1. Since T2 has read the value written by T1, it should also be rollbacked. As it has not committed, we can rollback T2 as well.

WebApr 27, 2024 · ROLLBACK is the explicit command (in most cases) of starting the UNDO process. You have a transaction that produces an error and your error handling code submits a ROLLBACK transaction to the DBMS. The DBMS receives the ROLLBACK command and UNDO-es the modifications. John K. N.
