There is a error while drop the tablespace
some tables on one tablespace , tablespace container was deleted ,its status is "off line"
i drop the tabalespace but occured the error code
SQL0282N Table space "TEST_DAT_TS" cannot be dropped because at least one of
the tables in it, "DB2INST2.TEST", has one or more of its parts in another
table space. SQLSTATE=55024

Some tables have indexes and/or LOBs stored in another tablespace. So, you have to drop all related tablespaces using a single "drop tablespaces" statement.
Example: db2 "drop tablespaces (x,y,z)"
