Re: Index size growing abnormally .....Oracle bug ?

Just tested it.

The answer is yes.

As a side effect,

    update test_reuse set idx_col = idx_col + 0.5     where idx_col = 100;

can cause a block to split if the block is full and the update entry is supposed to stay in that block.

Then I found that things could be worse when the consequences of fast commit and
delayed logging block cleanout apply.

More details when I have investigated fully.
