ACFSK-00096

Unaligned direct IO writes to compressed database rejected. The file has ACFS identifier %2 and is on the file system mounted at path %3 (device %4). Call %5 File Type %6

Cause

Attempted direct IO writes to a compressed database datafile were rejected because they were not aligned with the Compression Unit size of the file and would have caused corruption.


Action

If the configured database block size is not equal to the Compression Unit size then recreate the file with a block size supported by ACFS. If the database block size is equal to the Compression Unit size, contact Oracle Support Services.
