The following objects are imported to the mount host during a mount operation:
- Datafiles: The datafiles making up the database being mounted are included in the copy operation along with their respective one or more file systems, devices, volumes, or ASM diskgroups metadata. The datafiles include one or more corresponding UNDO tablespaces for each respective instance. However, the temp files and temporary tablespaces are not copied or backed up.
- Control files: The devices containing the current control files are included in the copy operation along with their respective one or more file systems, devices, volumes, or ASM diskgroups metadata. These objects are imported at the time of recovery and backup operations of the mount to be used.
- Online redo logs: The devices containing the online redo logs are included in the copy operation along with their respective one or more file systems, devices, volumes, or ASM diskgroups metadata. These objects are imported at the time of mount to be used for recovery and backup operations.
- Archive logs: If default hot-backup mode is used, the devices containing the archive logs are included in the copy operation along with their respective one or more file systems, devices, volumes, or ASM diskgroups metadata.
- Init file parameters: AppSync captures all initialization parameters that are associated with the database instance and copies them during mount in the form of an init file. This action is completed regardless of whether the production instance is using a spfile or pfile.
- Fast Recovery Area: If the Fast Recovery Area (FRA) is included in the copy, AppSync imports it during the mount operation. If you are including the FRA in the copy, the best option is to use hot backup mode with a mount read-write or read-only without database rename.
Note: Flashback commands are not integrated into AppSync and must be performed manually on the database. To perform a flashback command, shut down the instance, bring the database to a mounted state or startup mount, and run the flashback command manually. See Oracle documentation for more details.
