Question

Is there a way in DB2 to identify that a table is consuming how much of the total space allocated to the underlying table space.”

Thanks

Your question creates a false dichotomy because a tablespace may be created without allocating a limited amount of space to it. The limitation may rather be the drive or share that the tablespace is on. But if you know the space allocated to a tablespace or only need the percent of a tablespace’s current size that a table is using, then yes, there is a way to know.

SELECT * FROM SYScat.tables where tabname='mytable';

will tell you how many pages a table is using.

Then at the command line: LiST TABLESPACES SHOW DETAIL
will tell you how many total pages are in the tablespace and the size of a page in bytes.

Select * from sysibmadm.tbsp_utilization where tbsp_name='MyTblSpace' 

will give you the maximum size of the tablespace if it has one.
