Step 55 validating and copying link data
Thanks to the FAL_CLIENT and FAL_SERVER parameters, the managed-recovery process in the physical database will automatically check and resolve gaps at the time redo is applied.
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 description below provides an overview of the complete range of STM32F030x4/x6/x8/x C peripherals proposed.
These features make the STM32F030x4/x6/x8/x C microcontrollers suitable for a wide range of applications such as application control and user interfaces, handheld equipment, A/V receivers and digital TV, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms, and HVACs.
FAL_SERVER specifies the FAL (fetch archive log) server for a standby database.
The value is an Oracle Net service name, which is assumed to be configured properly on the standby database system to point to the desired FAL server.
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.
Prior to Oracle 11g, Redo Apply only worked with the standby database in the MOUNT state, preventing queries against the physical standby whilst media recovery was in progress. On Logical Standby, you can query it while simultaneously applying transactions from the primary.
This is ideal for business that requires a near real-time copy of your production DB for reporting.
Failover may or may not result in data loss depending on the protection mode in effect at the time of the failover.
