Hi, We have a big table and it has one field with CLOB datatype. Doing an export on this table is very slow. I have tried with different buffer sizes of 2MB - 250MB. It is still slow. Any way to speed up export and other operations on the table like update,delete. Thanks for your help. --------------------------------- Ring'em or ping'em.
