Ultimately, the project manager allowed each team member to determine his or her own estimate within a phase. The only estimate he imposed on the team member was to complete the phase while adhering to the deadline for the entire project. For some projects the area of responsibility dictates not only tasks but responsibility for an entire phase.

  • Restoration and Datafile Media Recovery Using RMAN RMAN automates the procedure for restoring files. When you issue the RESTORE command, RMAN uses a server session to restore the correct backups and copies. The RMAN repository is used to select the best available backup set or image copies to use in the restoration. By default, RMAN does not restore a file if the file is already in the correct place and its header contains the correct information. In releases before Oracle9i, the files were always restored.

  • When a transaction ends with a ROLLBACK operation, a possible approach is to simply abort the transaction in all replicas without verifying if previously returned results were correct (e.g., this solution is adopted in [13]). In our system, this could be easily implemented by execut- ing a BFT operation that aborts the transaction in each replica. This approach does not lead to any inconsistency in the replicas as the database state is not modified.
