we all know to build large indexes using many fast methods like parallel, nologging, etc.
how can i speed up dropping large local index partitions with sizes exceeding 400GB? it takes a couple of hours on a 64-CPU IBM p595 box. that's too much lost for me.
the mark index 'unsuable' trick doesn't help as my inserts/updates would fail.
since it is not an index supporting a PK, i was thinking of dropping only the index partition that i don't want (leaving the table partition intact). i could later on build the index partition after the data load.
is that the only "fast" method?
thanks in advance,
