Technical enthusiasts, after reading this article, you can master the following skills, and you can also learn some other knowledge that you do not know, ~ O (∩ _ ∩) Olympiad:
Failover handover drill process of ① physical dg
Some sql managed and maintained by ② physical dg
③ uses duplicate to build physical dg

1.2.4 introduction to this article
Follow up the previous article [DATAGUARD] switchover handover of physical dg (5): http://blog.itpub.net/26736162/viewspace-1753111/, this chapter introduces the handover of failover.
1.3 Literacy of related knowledge points
1. Role
There are two roles in the Oracle database.
User roles: defines a set of permissions that can be assigned to users or to other roles.
Database role: what role the database plays in the repository, primary or standby.
V$database.DATABASE_ROLE identifies the running role of the database.
In a repository environment, there are two types of databases: phsical standby and logical standby.
2. Role management service
A database runs in the following mutually exclusive roles.
Primary role: if a database runs on primary role, log transport services passes the redo log to the standby database.
Standby role: if a database runs on standby role, then the log apply services application archives the logs to the standby database.
Role management service allows users to dynamically switch roles between primary and standby libraries.
Users can use the role management service to switch roles in the planned master and slave libraries, which is called switchover, or unplanned role switching, called failover.
3.Switchover&Failover
Switching is a role reversal between the primary database and its standby database to ensure that data is not lost. This is a typical operation for planned maintenance of the primary system. During the switch, the primary database is converted to the standby role, and the standby database is converted to the primary role. The conversion does not require any database reconstruction.
(1) Switchover
Scenarios used: planned role conversion or maintenance of the user's operating system and hardware, etc.
(2) Failover
Failover is performed when the primary database is not available. Failover is performed only in the case of a disaster failure of the primary database, and the failover causes the standby database to be switched to the primary role. Scenarios used: unplanned role switching, usually used in emergencies. Depending on the protection mode, there may be no or little data loss.
(3) role transformation decision tree
The ultimate goal of role switching (switchover&failover) is to make the main database online as soon as possible, while minimizing data loss or achieving no data loss. Try to choose the strategy with the shortest downtime and the least data loss. In short, before failing to switch, you should consider repairing the primary database or changing roles with numerous data losses.
Even if you use a standby solution with no data loss, it may be faster to repair the primary library than to switch to the standby library. If the main library is fixed, there is no need to modify the client connection. But if the repair results in any data loss, you may need to recreate all the standby databases.
In general, the standby database that is most suitable for switching is the standby database that has applied the most archive logs.
1.4 Experimental Section 1.4.1 Experimental objectives
Failover switching between ① main Library and physical dg
② is restored to its original state
1.4.2 Experimental process
Note: after failover switching, the original main library will not be available and must be rebuilt, so please choose this experiment carefully.
1.4.2.1 simulate unexpected database downtime on the main database side

At this point, all the experiments have been completed, and the database has been restored to its original state.
3. Conclusion
1.4.3 Summary of experiments
Failover is an important functional feature of Dataguard. After Failover, we think that the Primary site can no longer be a member of the HA architecture. There are three ways to rejoin Primary: one is to use RMAN backup to restore Primary to failover, and then perform log compensation and role switching; the second is to use Flashback Database strategy to restore the database to the point in time before failover; and the third is to delete the Primary database and re-use the new Primary to build standby.
1.5 Summary
Dataguard switchover and failover are very common operation and maintenance requirements. In the actual scenario, we try our best to choose a safe and complete strategy to operate. The SQL command is still a better choice, and we will be familiar with it after a few more operations.
