A storage group named MED_SG was created as follows: CREATE STOGROUP med_sg ON ?db2fs1? ?db2fs2? '/db2fs3' Then, a table space named TS1 was created in the storage group and two tables (TAB_A and TAB_B) were created in the TS1 table space. Four months later, a DBA discovered that 90% of the space that had been allocated to the MED_SG storage group had been consumed. So, more space was added to the storage group by executing the following command: ALTER STOGROUP med_sg ADD ?db2fs4? ALTER STOGROUP med_sg ADD ?db2fs4 Shortly afterwards, queries against tables in the TS1 table space began to run slower. Which statement should be executed to correct the performance problem?
