Oracle has developed system and protocols that offers solution to any data loss situation you and your company require. Data loss is fairly common especially with vulnerable systems and the only way to protect yourself and your system from any malicious and potentially unsafe data loss is to take on the Oracle data recovery advisor.
The chief purpose of oracle data recovery advisor is to provide a database tools that helps to diagnose data systems failure. This is sequentially followed by the recommendation of appropriate repairs and finally the execution of the repair as deemed necessary.
The whole process involve the;
Early detection and hence early warning of errors and corruption of database from the harm that could precede after. Assessing symptoms of the cause of data fails and farther describing the effects. Data recovery advisor then automatically determines the best repair approach for speedy and thorough action. Afterwards, checks are run to determine the success of the actions executed. The whole aspect and protocol of using oracle data recovery advisory is all rooted on the protection of database but other issues pertaining system problems may arise and they involve;
1.Data integrity checks
This involve the deployment of a health monitor to assess the health of your database and the entire system. It can be executed randomly by the oracle data recovery advisor or on the command of the user. It often involves checking the systems for the smallest of errors and failings that could progressively lead to bigger problems. The whole process then is recorded in the automatic diagnostic repository (ADR) which is a directory structure that stores all information outside the system itself.2.
2. Diagnosis and determination failings
Failings that are often encountered by the oracle data recovery advisor involves; data files that are corrupted, database access problems, I/O failings including OS fallings, hardware errors, and resources of the OS and hard dives is limited and so many more.
3. Failure status
This is often deemed open or close, open involve failing that have been acted on and closed often involves failing that have been acted on and repaired accordingly. The list failure is often involved in determination of closed and opened failure status.
Valued as critical, high or low and appraise action is taken as for example with critical immediate action is often involved.
Were all failings deemed to be characteristically similar are grouped together. Finer details are then provided to each failing. This helps to access how healthy a part of the system is, if it faces many failings then drastic steps could be taken.
Understanding Oracle data recovery advisor is complex and it helps if you have an expert to take you through. This is just the tip of the spa era as Oracle data recovery advisor has other more components such as automatic and manual repair protocols, oracle data guard, validating failings and others.
