Are these bitmap indexes? Bitmap indexes with lots of table updates would
cause something like this.

If not, then checking statspack report is warranted.

Dear All,



I have a table (partitioned - list) with approx. 500 million rows.

I have two indexes (partitioned - list) on this table in their own
separate tablespace.



Size of table is roughly 50GB and sizes of the two indexes currently are

17 GB each.



For the past 4 days, I have noticed that space is consumed in the index
tablespace at the rate of 1 GB per day.



This has never happened before and I have been racking my head as to the
reason why this is happening.



One thing I could think of was a 50: 50 block split when new values have
to be inserted in the index.



Is there any way I can check this or any other ideas why this could be
happening?



And is indexes rebuild necessary or warranted here?



Thanks,







G. Nizar A. Baig
