Recovery is an important component of DBMS.This paper proposes a method of database recovery technique based on Redo log,Undo log and checkpoint.Moreover,we introduces its design and implementation in DM3 in detail.Finally,we write its recovery algorithm....

All logs are created and stored in stable storage when the deferred database method is used, and data is synced to the database when a transaction commits.Discuss this Question 9. Modifications to the database occur while a transaction is still active, using the ___ modification technique....
involved in SAP workload are replicated to the DR region using different techniques (Azure native services, native DB replication technology, custom scripts). Each technique provides different RPO, which must be accounted for when designing a DR strategy. On Azure, you can use some of the Azure...
In Figure 2-1, the central Recovery Appliance uses Oracle Secure Backup software to communicate with a tape device. Also, the Recovery Appliance furthest downstream in the replication scheme archives its backups to tape. This technique has the following benefits: To create redundancy, identical back...

Pointing Exchange to the location of the storage group copy may not be the best technique, because it involves modifying the Exchange configuration and potentially causes confusion if left like that for an extended period. However, it's possible to perform the recovery operation while keeping the ...
However, RMAN supports the following alternatives for controlling the location of auxiliary set datafiles, which are listed in order of precedence shown in Table 21-3. Table 21-3 Order of Precedence for Naming Files OrderTechniqueSection 1 SET NEWNAME "Using SET NEWNAME to Name Auxiliary Set ...
Results logging has low logging overhead in the usual e- commerce setting where the results are modest in size. At most one log flush by middleware servers is required for a transactional method execution. This low overhead yields excellent performance for our technique. Further, little or no ...
