Step 55 validating and copying link data

There are no restrictions on where the databases are located, provided that they can communicate with each other.

Enables and controls the automated transfer of redo data within a Data Guard configuration from the primary site to each of its standby sites.

The STM32F030x4/x6/x8/x C microcontrollers include devices in four different packages ranging from 20 pins to 64 pins.

Depending on the device chosen, different sets of peripherals are included.

Quick Steps for creating the Physical Standby from a Hot backup Logical Standby Implementation with RMAN (Recommended) Logical Standby Implementation Logical Standby Sanity Check Troubleshooting a Logical Standby Logical Standby Database Activation (Role Transition) - Switchover and Failover Oracle Data Guard is the management, monitoring, and automation software that works with a production database and one or more standby databases to protect data against failures, errors, and corruption that might otherwise destroy your database.

A physical or logical standby database is a database replica created from a backup of a primary database.

Oracle (or more exactly the log apply services) uses the primary database's redo log, transforms them into SQL statements and replays them on the logical standby database.

SQL Apply uses LOGMINER technology to reconstruct DML statements from the redo generated on the primary.

FAL_CLIENT and FAL_SERVER only need to be defined in the initialization parameter file for the standby database(s).

It is possible; however, to define these two parameters in the initialization parameter for the primary database server to ease the amount of work that would need to be performed if the primary database were required to transition its role.

FAL_CLIENT specifies the FAL (fetch archive log) client name that is used by the FAL service, configured through the FAL_SERVER parameter, to refer to the FAL client.
