Home -> Community -> Mailing Lists -> Oracle-L -> FW: ORA-28604, Table too fragmented
> I received the following error when trying to create a bitmap index:
>
> 28604, 00000, "table too fragmented to build bitmap index (%s,%s,%s)"
> // *Cause: The table has one or more blocks that exceed the maximum
> number
> // of rows expected when creating a bitmap index. This is
> probably
> // due to deleted rows. The values in the message are:
> // (data block address, slot number found, maximum slot allowed)
> // *Action: Defragment the table or block(s). Use the values in the
> message
> // to determine the FIRST block affected. (There may be others).
>
> How do deleted rows mess up the slot count?
> What sql could I issue to find this out?
> What additional sql would indicate that a table should be reorged?
>
