Other SQL operations that might require disk sorting are: CREATE INDEX, ANALYZE, Select DISTINCT, ORDER BY, GROUP BY, UNION, INTERSECT, MINUS, Sort-Merge joins, etc.

You can use the AUTOEXTEND clause to override this default extensibility and the SIZE clause to override the default size. ASM applies attributes to the datafile, as specified in the system default template for a datafile as shown in the table in “Managing Disk Group Templates”. You can also create and specify your own template. Files in a tablespace might be in both ASM files and non-ASM...
