    Hi,
    Yesterday, I had a problem as
    'Unable to extend Index REI.USAGE_ACCOUNT_ID_IDX' by 65536 in tablespace REI_PROD_INDEX.

    So I added another datafile of 500M to rei_prod_index tablespace.
    But still I am getting the same problem.

    Should I extend the extents only to the REI.USAGE_ACCOUNT_ID_IDX only. Please help

    I checked up in my dba_indexes. For Usage_account_id_idx, (on the table REI_USAGE_HISTORY), the Initial extents is

    536870912 and Next is 536870912 and the max extents is 100.

    What to do next?

    according your storage parameters, you need 512MB not 500MB, thatīs the problem

    On the table REI_USAGE_HISTORY, I have an index 'USAGE_ACCOUNT_ID_IDX', for which the initial and next are
    536870912. As I got this error ORA-01654, I added another 500M only. Is this small for extending the next extent.

    As the error say 'Unable to extend index REI.Usage_account_id_idx' by 65536.

    What does it mean by saying '65536' while my next extent size is different (512M).

    There is possibility that index has object level storage definition and you are talking about tablespace level storage clause(512M).

    It says it needs 65536 *contiguous* db blocks in that tablespace to create next extent for your index. If you multiply this number of blocks with your block size (which obviously is 8K) you'll get exactly 512MB. So your datafile of 500MB can not be used for that extent, it is too small. Even adding another smaller datafile will not help, as the blocks in those two files will not be contiguous and an extent can not span across different datafiles.

    So you only have two options:
    a) enlarge your 500M datafile or create a new one of sufficient size OR
    b) modify the NEXT storage parameter of your index (make it smaller)
