org.apache.derby.io.StorageRandomAccessFile.sync()
Force any changes out to the persistent store. If the database is to be transient, that is, if the database does not survive a restart, then the sync method implementation need not do anything. @param metaData If true then this method must force both changes to the file'scontents and metadata to be written to storage; if false, it need only force file content changes to be written. The implementation is allowed to ignore this parameter and always force out metadata changes. @exception SyncFailedException if a possibly recoverable error occurs. @exception IOException If an IO error occurs.
