Oracle database space
The sum of sm$ts_free.bytes
and sm$ts_used.bytes
is not equal to sm$ts_alloc.byte开发者_JAVA技巧s
.
What can be the reason behind it?
There is a discussion about these views in the OTN forum. It seems the difference between sm$ts_free.bytes + sm$ts_used.bytes
and sm$ts_alloc.bytes
is a constant overhead. It is probably used to store tablespace header information.
