Moving 12c database from NON-ASM to ASM
Download as DOCX, PDF0 likes973 views
The document describes the steps to move an Oracle 12c database from a non-ASM storage to ASM storage. It involves: 1. Checking the current database files and parameters. 2. Creating required directories in ASM for datafiles, controlfiles, online logs etc. 3. Configuring the fast recovery area. 4. Backing up the database files and control file, copying them to ASM, and switching to the copies. 5. Adding new online redo logs to ASM and dropping the old logs. 6. Adding a new tempfile to ASM and dropping the old tempfile. 7. Creating a new SPFILE in ASM.
