DETAILS
Oracle ACFS Support on Exadata Database Machine
Starting with Oracle Grid Infrastructure 12
c
Release 12.1.0.2, Oracle Automatic Storage Management File System
(ACFS) supports all database files and general purpose files on Oracle Exadata Database Machine running Oracle Linux
on database servers. Please refer to the
Oracle Automatic Storage Management Administrator's Guide
for details on
how to configure and administer Oracle ACFS.
On Exadata Database Machine, Oracle ACFS supports the following database versions:
Database 11.2.0.4 and higher
Database 10.2.0.4 and 10.2.0.5 - see Document 1965897.1 for additional details
Review Document 888828.1 for specific Grid Infrastructure version and patch requirements.
The following list provides important information about using Oracle ACFS with Exadata:
Oracle ACFS supports all database file types, database software binaries (database ORACLE_HOME), and general
purpose files.
IMPORTANT: Mission-critical databases should not use ACFS for any of the following:
Database files (e.g. data files, control files, and redo log files)
Database home software/binaries (ORACLE_HOME)
Administrative files (e.g. diagnostic, trace, and audit directories - audit_file_dest,
background_dump_dest, core_dump_dest, diagnostic_dest, user_dump_dest)
Store database files in ASM. Use a local disk file system (e.g. /u01) to store database home software/binaries
and administrative files.
Oracle ACFS snapshots should only be used for test/development databases.
