Oracle Database Error ACFS-03684: ACFS Compression Incompatibility
Description
This error indicates that a file on an ACFS filesystem, intended for use by Oracle Database, has been compressed using settings (specifically, a compression unit size) that are incompatible with the RDBMS. It typically occurs when ACFS compression is enabled on files that Oracle Database expects to manage directly with its own block size, rendering them unusable by the database instance.
Error Message
File string with internal block size string bytes is being compressed with compression unit size string bytes. It will not be usable by the RDBMS.
Known Causes
3 known causesIncompatible ACFS Compression
ACFS compression has been applied to files that Oracle Database requires to be uncompressed or compressed using database-native methods.
Compression Unit Size Mismatch
The ACFS compression unit size is not compatible with the internal block size expected by the Oracle RDBMS for the affected file.
Misconfigured ACFS Filesystem
