In my last article<\/a>, I demonstrated that starting with Oracle Grid Infrastructure 12c (12.1), Oracle Cloud File system (ASM Cluster File System in cluster environment) supports database files (database version 11.2.0.4 and up) in addition to general purpose files, so that entire Oracle databases can be stored inside Oracle Cloud FS. In addition, for a database with its files stored on Oracle Cloud file system, Oracle ACFS Snapshots may serve as point-in-time backups of the database which can be used for online recovery of database files.<\/p>\n

In this article, I will demonstrate that ACFS snapshots can be integrated with RMAN and hence employed to perform complete recovery using RMAN RESTORE \/ RECOVER commands, thereby complementing RMAN functionality.<\/p>\n

Currently\u00a0I am working in an Oracle Database 12.1.0.2 cluster environment and have created a database named cfsdb, with all of its files stored on the cloud file system as shown below:<\/p>\n

Thus, we have been able to perform complete recovery by employing:<\/p>\n
    \n
  • OS commands to copy the datafile from the snapshot example_dbsnap taken while the database was in backup mode.<\/li>\n
  • RMAN RECOVER command to perform complete recovery using Archived logs stored in FRA (\/mnt\/acfs).<\/li>\n<\/ul>\n
    Now, let us explore if we can catalog the datafile copies stored in the snapshot with RMAN and hence employ RMAN for RESTORE as well as RECOVER.<\/p>\n
    Catalog all the files in the snapshot example_dbsnap in directory \u201c\/mnt\/acfs\/.ACFS\/snaps\/example_dbsnap\/oradata\/cfsdb\/\u201d<\/h3>\n

    It can be seen that all the datafile copies have been catalogued whereas SPfile and controlfile have not been registered with RMAN.<\/p>\n
    Now we will again simulate the loss of datafile for the EXAMPLE tablespace, and then we’ll attempt to employ RMAN for RESTORE as well RECOVER.<\/p>\n
