How to increase space in Bigfile Tablespace?


BIGFILE tablespace stores its data in a single datafile with a much larger capacity.

We can resize the size of the datafile in BIGFILE tablespace using ALTER DATABASE Command


ALTER DATABASE DATAFILE '/+DATA/df0101.dbf' RESIZE 180G;

Since BIGFILE Tablespace has only one datafile, there is no need to identify the datafile and increase its size.
We can use ALTER TABLESPACE command to resize at the tablespace level.

ALTER TABLESPACE BIG_TBSP1 RESIZE 180G;
