    Partition Indexes ????

    I had some partitioned tables by range each month and I used local partition index for these tables. For monthly, I dropped some old partitions then some local index of these tables were failed (unusable), I must be rebuilded them. But the time to rebuild index was very long and application can't access these index at rebuilding time.
    Have any way to drop old partition and appropriate indexes is not failed? How about Global Partition Indexes? Can I create indexes on each partition (EX : seperate 12 indexes for 12 partitions of months)?

    Please help me.
    Thanks,
    Sinh

    Oracle is doing what it's supposed to do.

    Oracle version?
    Size of the target table?
    Number of indexes?
    Could you define "very long"?
    Have you read documentation about partitioned tables/indexes?

    If these truly were local indexes then dropping the table partitions should have dropped the associated index partitions.

    Sorry for delaying,

    Currently, My table is SETTLE_CDR, partitioned on CREATE_TM column and I had a uniqe index on 2 columns (FILE_ID, SEQ_NO). I want to change this index to local uniqe index on partitions. As I know, we must add CREATE_TM to local uniqe index then we can create local uniqe index. But if do that then logical bussiness is wrong, beacause uniqe index only on 2 columns (FILE_ID, SEQ_NO), not for 3 columns (FILE_ID, SEQ_NO, CREATE_TM).

    Have any way to create local uniqe index on only 2 columns (FILE_ID, SEQ_NO) ?
    I need your comments for my proplem.

    Thanks,
    Sinh
