Install Oracle database 23 for engineered systems and create a physical standby database using DataGuard. Explore DataGuard usages for disaster recovery, high availability, read-only offload, and rolling upgrades.
Explore high availability strategies with Oracle Flashback and Active Data Guard, enabling real-time queries, offloaded backups, and block recovery between primary and physical standby databases.
Create a practice virtual machine to install Oracle Linux 9.4, configure the OS, install Oracle software, and set up Oracle Database 23 and a physical standby database.
Learn Oracle installation prerequisites by verifying memory and swap sizes, preparing directories, configuring environment files and bash profiles, and creating startup scripts with proper permissions.
Install Oracle database 23.5 for systems, perform GUI setup software only, create a single instance enterprise edition, and clone the machine to a standby database with hostname and IP updates.
Learn how to create a primary database using DBCA on a cloned environment, configuring a single instance with SID Database23AI, memory settings, and Exadata feature adjustments for non-engineered systems.
Enable archive log mode on the primary database, configure Data Guard parameters like db_unique_name and log_archive_config, set up standby redo logs, and prepare listener and tnsnames.ora for primary-to-standby communication.
Prepare the standby by creating directories, copying and renaming the password file to BW<standby_sid>, configuring DNS and listener, and restarting the listener to enable a physical standby.
Create the standby database from the primary using RMAN, after starting the listener and standby instance in no-mount, then run DuplicateTargetDatabaseForStandbyFromActiveDatabase with init parameter changes to initialize locations and destinations.
Verify the standby instance is running via sqlplus, locate the data file db23aistby, and confirm Data Guard status with zero differences between received and applied sequences.
