The target standby host has all the required Oracle software installed and configured.have a minimum of 3 groups for each thread of a RAC database.are multiplexed on NORMAL redundancy disk groups (HIGH redundancy disk groups are not multiplexed).are sized so they do not switch more than 6 times per hour at peak redo generation (this can significantly impact redo apply in Data Guard).

The primary database is in archive log mode.

A primary database utilizing ASM for data file storage as well as Oracle Managed Files(OMF).

See note 2275154.1 for details on assessing the network.

The network between the primary and standby sites is reliable and has been assessed and determined to support the peak redo generation rate of the primary.

This paper assumes that the following conditions exist: This method is useful in synchronizing the primary and standby database. NOTE: This вЂFROM SERVICEвЂ method can be used to restore or recover an entire database, individual data files, control files, server parameter file, or tablespaces. Additionally, utilizing the SECTION SIZE clause with multiple RMAN channels improves the efficiency of parallelization of the restore, further improving instantiation times. This functionality can be used to instantiate a standby database in lieu of the RMAN DUPLICATE DATABASE command and is more intuitive and less error prone thus saving time. The RMAN вЂfrom serviceвЂ™ clause enables the restore and recover of primary database files to a standby database across the network. CPU resources and increased elapsed time) can be significant. using OLTP, HCC compression) or encrypted since the compression benefits is very small and the overall impact (e.g. It is not recommended to use compression on backups or data that has already been compressed (e.g. This improves the overall efficiency of parallelization across channels. The section size clause used with multiple RMAN channels enables parallelization of individual files by dividing large files into smaller pieces.

This document applies to Oracle Database Server versions 12.1 to 19c and higher.Provide a step-by-step guide for instantiating a standby database using the RMAN вЂњ from serviceвЂќ clause to copy directly from the primary database through an Oracle Net connection.
