What does coalescing a tablespace do?

Question Posted / guest


What does coalescing a tablespace do?..

Answer / guest

If we find that fragmentation of space in a tablespace is
high (contiguous space on our disk appears as
non-contiguous),we can coalesce any free space using the

ALTER TABLESPACE TABLESPACE_NAME COALESCE ; command

We must have the ALTER TABLESPACE system privilege to
coalesce tablespaces.
