What is the best way to truncate 1000 tables at a time ? Most of the table are of INITIAL size of 14M each. Also, some of the table contains CLOB column. We found that truncate all take more than 15 minutes. Any way to improve the speed ? We also tried the reuse storage, but the effect is not so obvious. Any advice ?

No way to speed up truncate which requires to checkpoint each object which is an expensive operation especially in RAC.
15 minutes is quite good for 1000 tables.
