Logical standby database A logical standby database Hp data protector disastor recovery the same logical information as the primary database, although the physical organization and structure of the data can be different.
Also, see Table for a summary of the attainable recovery times for all types of unplanned downtime for each Oracle high availability architecture. If such risks or uncertainties materialize or such assumptions prove incorrect, the results of HP and its consolidated subsidiaries could differ materially from those expressed or implied by such forward-looking statements and assumptions.
The benefit is that the time it takes to discover block corruptions is shortened. The key approach is block checking where the storage subsystem validates the Oracle block contents. Also, each vendor's implementation is unique and their control interfaces may have different features.
Note When you restore a database backup onto a different server instance, see Copy Databases with Backup and Restore. Assessing these symptoms can be complicated, error-prone and time-consuming. Failure Impact Assessment After a failure is diagnosed, you must understand its extent and assess its impact on applications before devising a repair strategy.
Using Oracle Streams, each unit of shared information is called a message, and you can share these messages in a stream. File system backup at the file, directory, file system or raw partition level with full, incremental and offsite backup scheduling.
Figure Oracle Data Validation Storage vendors may choose to implement some or all of the checks in their implementation.

To restore the database to the state is was in at 5: Data protection and fast repair against computer failures, human errors, data corruption, lost writes, and site failures. Scalable, low-cost licensing model reduces IT costs and operational considerations.
Restore the full database backup that was created Tuesday at midnight. With Oracle Flashback Database, current data files can be reverted to their contents at a past time. They cannot be backed up to disk. Although it is possible to configure a hub-and-spoke configuration for bidirectional replication, you may prefer to restrict updates to a single location, the hub, as shown in Figure It provides a fast, online solution for recovering a table or set of tables that has been modified by a human or application error.
You can also put user-defined messages into a stream, and Streams can propagate the information to other databases or applications automatically. Flashback technology provides fine-grained analysis and repair for localized damage such as deleting the wrong customer order.
Simplifying application design by removing the need to store certain types of temporal data. See also "Benefits of Snapshot Standby Databases". In addition, while you can use Data Recovery Advisor when managing a primary database in a Data Guard configuration, you cannot use Data Recovery Advisor to troubleshoot a physical standby database.
Auditing control to monitor and gather data about specific database activities, investigate suspicious activity, deter users or others from inappropriate activities, and detect problems with authorization or access control implementation.
If there are multiple failures present, you must also determine the best sequence of repair steps. A failure group is a set of disks sharing a common resource disk controller or an entire disk array whose failure can be tolerated. It leverages real-time operational analytics and defined business requirements to intelligently monitor, adapt and optimize how an organization manages its storage infrastructure, resources and data policies.
Oracle Database Reference for more information about these views and initialization parameters 2. However, Flashback Database skips the data file restoration and most of the application of redo data. Moreover, local updates to the snapshot standby database cause additional divergence.
Oracle Flashback Versions Query returns a row for each version of the row that existed in the specified time interval. The best way to prevent human errors is to restrict user access to only those data and services truly needed to perform business functions.
Undo data is persistent and survives a database malfunction or shutdown. Can have its data physically reorganized into a different storage type with different partitioning having many different indexes, and having on-demand refresh materialized views created and maintained.
Automatic or automated resynchronization of a failed primary database following a failover. LogMiner is a fully relational tool that allows redo log files to be read, analyzed, and interpreted using SQL. Because human errors can be quickly undone, it allows standby databases to use real-time apply to synchronize with the primary database.
Event management and notification by enqueuing messages or capturing events, propagating the messages and events through queues, and dequeuing and applying or acting upon the message or event as shown in Figure Supports heterogeneous platforms across databases in the configuration Allows character sets to differ between replicas Permits fine-grained control of data sharing Note: For example, rows that have been deleted or updated can be immediately repaired even after they have been committed.
