12c database migration from ASM storage to NON-ASM storage
Download as DOCX, PDF0 likes546 views
1. The document describes the process of migrating a database from ASM to non-ASM storage. This involves taking backups, changing initialization parameters, creating new datafiles and redo logs in non-ASM locations, mounting and opening the database. 2. Key steps include taking an ASM backup, creating a pfile with new datafile and logfile locations, restoring the controlfile, copying datafiles to the new locations, renaming datafiles, and adding new redo logs. 3. After completing these steps, the database is successfully migrated from ASM to non-ASM storage, with the datafiles and redo logs now residing in normal filesystem locations instead of ASM.
