A new table with 100 free blocks has inserts filling 70 blocks followed by deletes freeing 20 blocks. Where is the resulting high water mark at this point?
70 Blocks (INITRANS Index > INITRANS Table) The high water mark in a table is the last block ever used by the table. The high water mark is not reset when data is deleted. When a full table scan is performed, each block is read up to its high water mark. • You are creating an index for a table and are considering a value for INITRANS for this index. How should INITRANS be set for this index relative to the INITRANS value already set for the corresponding data table? Higher Because index entries are small, there are usually more entries per block so the INITRANS value should be higher than the table.
