Lee,

I think you should be able to do the following:

export the data from the partition
drop the partition (which will in turn drop the local index for that partition)
recreate the partition (which will create the local index)
reload the data

Have you considered moving the partition? Maybe that would clear up the fragmentation? I'm honestly not sure.

All,

I have a partition of a table which has become fragmented. The plan is to extract the data, drop the index and reload the data then close it off. This will free up a bit of disk for us.

My question is how feasible is this. Can the index partition be rebuilt purely for the partition we are unloading/reloading. I did an exp then an imp with indexfile to get out the sql and it says the index is LOCAL. From what I glean from the documentation, this means that it is possible to do what we originally planned.

I would appreciate any hints or gotchas from anyone who has experience of this type of situation or indeed from anyone who has a good background in Oracle 8 (which I don't - YET !!).

Regards

Lee Robertson
